Description

Server device and detachable expansion card assembly thereof

The present invention relates to a server device, in particular to a server device with a detachable expansion card assembly.

As network functions gradually increase, servers nowadays will add multiple sets of computing elements to meet cloud demands. These computing elements are, for example, GPU interface cards. In the conventional layout of server devices, GPU interface cards are usually fixedly installed on the inner wall of the chassis.

However, due to the limited internal space of server devices, the number of GPU interface cards that can be accommodated in the server device and the ease of installation will affect consumers' purchasing and usage intentions.

It can be seen that the above technology still has inconveniences and defects, and needs to be further improved. Therefore, how to effectively solve the above inconveniences and defects is one of the important research and development topics at present, and has also become a goal that needs to be improved urgently in the current related fields.

One purpose of the present invention is to provide a server device and a detachable expansion card assembly thereof to solve the difficulties mentioned in the above prior art.

According to one embodiment of the present invention, a detachable expansion card assembly includes a fixed frame, at least one circuit side plate and at least one expansion card module. The fixed frame includes a main frame module and at least one first card slot portion. One side of the main frame module has a storage slot. The first card slot portion is formed on the main frame module and connected to the top of the main frame module. The circuit side plate includes a wiring board and a card slot, the wiring board is fixed to the main frame module, and the card slot is arranged on the wiring board. The expansion card module has at least one clamping portion, the clamping portion is located at one end of the expansion card module, and the clamping portion can be removably moved in and out of the first card slot portion. Therefore, guided by the first card slot portion, the expansion card module can enter the storage slot along a first straight line direction from the top of the main frame module, and be inserted into the card slot along a second straight line direction, and the second straight line direction is orthogonal to the first straight line direction.

According to one or more embodiments of the present invention, in the above-mentioned detachable expansion card assembly, the first card slot portion includes a first channel and a second channel. The first channel is formed on the inner wall surface of the main frame module facing the storage slot, connected to the top of the main frame module, and parallel to the first straight line direction. The second channel is formed on the inner wall surface of the main frame module facing the storage slot, connected to the first channel, and parallel to the second straight line direction.

According to one or more embodiments of the present invention, in the above-mentioned detachable expansion card assembly, the expansion card module includes a first expansion card module and a second expansion card module.

The fourth channel is formed on the inner wall surface of the main frame module, connected to the third channel, and parallel to the second straight line direction. Therefore, when the engaging portion of the first expansion card module moves from the first channel through the third channel to the fourth channel, the first expansion card module moves to the card slot of the first circuit side plate at a first height. When the engaging portion of the second expansion card module moves from the first channel to the second channel, the second expansion card module moves toward the card slot of the second circuit side panel at a second height greater than the first height and overlaps with the first expansion card module.

According to one or more embodiments of the present invention, in the above-mentioned detachable expansion card assembly, the inner wall surface of the main frame module facing the storage slot further includes a protrusion. The expansion card module further includes at least one booster, and the booster includes a rotating disk and a pivoting portion. The pivoting portion is on the rotating disk, and the rotating disk is rotatably connected to the expansion card module. The outer edge of the rotating disk has a recessed portion, and the recessed portion accommodates the protrusion therein. Therefore, when the rotating disk is rotated, the inner wall of the recessed portion squeezes the protrusion, and the expansion card module is pushed by the protrusion to enter and exit the card slot.

According to one or more embodiments of the present invention, in the above-mentioned detachable expansion card assembly, the fixed frame further includes a blocking hole. The rotating plate has a through hole. The expansion card module further includes a lever-type plunger. The lever-type plunger can be retracted and positioned in the through hole. Therefore, when the through hole overlaps the blocking hole, the lever-type plunger can extend into the blocking hole and fix the expansion card module on the fixed frame.

According to one or more embodiments of the present invention, in the above-mentioned detachable expansion card assembly, the first card slot portion includes two first card slot portions, which are formed on the main frame module opposite to each other, and the engaging portion includes two engaging portions.

The circuit side panel includes a wiring board and a card slot, the wiring board is fixed to the main frame module, and the card slot is arranged on the wiring board. The expansion card module includes at least one engaging portion. The engaging portion is located at one end of the expansion card module and can be removably moved in and out of the first card slot portion. Therefore, by the guidance of the first card slot portion, the expansion card module can enter the storage slot along a first straight line direction from the top of the main frame module, and be inserted into the card slot along a second straight line direction, and the second straight line direction is orthogonal to the first straight line direction.

According to one or more embodiments of the present invention, in the above-mentioned server device, the first card slot portion includes a first channel and a second channel. The first channel is formed on the inner wall surface of the main frame module facing the storage slot, connected to the top of the main frame module, and parallel to the first straight line direction. The second channel is formed on the inner wall surface of the main frame module facing the storage slot, connected to the first channel, and parallel to the second straight line direction.

The fourth channel is formed on the inner wall surface of the main frame module, connected to the third channel, and parallel to the second straight line direction. Therefore, when the engaging portion of the first expansion card module moves from the first channel to the fourth channel via the third channel, the first expansion card module moves to the card slot of the first circuit side plate at a first height. When the engaging portion of the second expansion card module moves from the first channel to the second channel, the second expansion card module moves toward the card slot of the second circuit side panel at a second height greater than the first height and overlaps with the first expansion card module.

According to one or more embodiments of the present invention, in the above-mentioned server device, the inner wall surface of the main frame module facing the storage slot further includes a protrusion. The expansion card module further includes at least one booster, and the booster includes a rotating disk and a pivoting portion. The pivoting portion is on the rotating disk, and the rotating disk is rotatably connected to the expansion card module. The outer edge of the rotating disk has a recessed portion, and the recessed portion accommodates the protrusion therein. Therefore, when the rotating disk is rotated, the inner wall of the recessed portion squeezes the protrusion, and the expansion card module is pushed by the protrusion to enter and exit the card slot.

According to one or more embodiments of the present invention, in the above-mentioned server device, the fixed frame further includes a stop hole. The rotating plate has a through hole. The expansion card module further includes a lever-type plunger. The lever-type plunger can be retracted and positioned in the through hole.

The following will disclose multiple embodiments of the present invention with drawings. For the purpose of clarity, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. In other words, in each embodiment of the present invention, the practical details are not necessary. In addition, in order to simplify the drawings, some commonly used structures and components will be depicted in a simple schematic manner in the drawings.

FIG. 1 is a three-dimensional diagram of a server device 10 of an embodiment of the present invention. FIG. 2 is an exploded diagram of two detachable expansion card assemblies 200 in FIG. 1. As shown in FIG. 1 and FIG. 2, the server device 10 includes a chassis 100 and two detachable expansion card assemblies 200. The chassis 100 has a bottom plate 101, two side walls 102, a front end plate 103 and a rear end plate 104. These side walls 102 are respectively located at two opposite sides of the bottom plate 101, and the front end plate 103 and the rear end plate 104 are located at two opposite ends of the bottom plate 101 relative to each other, so that the bottom plate 101, these side walls 102, the front end plate 103 and the rear end plate 104 jointly define a accommodating space 110. However, the front end plate 103 and the rear end plate 104 are non-essential components in the present invention.

The two detachable expansion card assemblies 200 are relatively located in the accommodation space 110. Each detachable expansion card assembly 200 includes a fixed frame 210, a plurality of (such as two) circuit side panels 300 and a plurality of (such as two) expansion card modules (hereinafter referred to as the first expansion card module 400 and the second expansion card module 500). The fixed frame 210 has a main frame module 220. The main frame module 220 is fixed in the accommodation space 110, for example, fixed on the bottom plate 101. The main frame module 220 is U-shaped and has a receiving slot 260 and two first card slot portions 280. The receiving slot 260 is provided on one side of the main frame module 220 facing the side wall 102. These first slots 280 are located opposite to each other in the receiving slot 260 and are located on two opposite sides of the main frame module 220 facing the receiving slot 260, and these first slots 280 are all connected to the top 212 of the main frame module 220. The top 212 is arranged opposite to the bottom plate 101 and is adjacent to the inner wall surface 211 of the main frame module 220 facing the receiving slot 260.

Each circuit side panel 300 includes a wiring board 310 and at least one card slot 320. The wiring board 310 is fixed to the main frame module 220, and the card slot 320 is located on one side of the wiring board 310 facing the storage slot 260. The two opposite ends of each expansion card module (such as the first expansion card module 400) are respectively configured with a clamping portion 410, and each clamping portion 410 can be removably moved in and out of the corresponding first card slot portion 280. Therefore, when a user wants to install the first expansion card module 400, the user moves each clamping portion 410 of the first expansion card module 400 into the corresponding first card slot portion 280. It should be understood that FIG. 2 only shows the engaging portion 410 at one end of the first expansion card module 400, and FIG. 4 shows the engaging portions 410 respectively arranged at both ends of the first expansion card module 400.

Thus, as shown in FIG. 3A, guided by the first card slot portion 280, the first expansion card module 400 moves downward from the top 212 of the main frame module 220 along a first linear direction (such as the Z axis) into the storage slot 260; then, the first expansion card module 400 moves along a second linear direction (such as the Y axis) orthogonal to the first linear direction (such as the Z axis) to and is inserted into the corresponding card slot 320 of the circuit side panel 300. At this time, one main surface 401 of the first expansion card module 400 faces the bottom panel 101 (FIG. 1). On the contrary, by the reverse guidance of the first card slot portion 280, the user pulls the first expansion card module 400 out of the card slot 320 of the circuit side panel 300 and moves upward out of the storage slot 260, so that the top 212 of the main frame module 220 is completely separated from the chassis 100.

More specifically, as shown in FIG. 2 , the main frame module 220 includes a main side frame 230, a front side frame 240 and a connecting side frame 250. The main side frame 230 and the front side frame 240 are fixed to the bottom plate 101, respectively, and the two ends of the connecting side frame 250 are respectively locked to the main side frame 230 and the front side frame 240, so that the main side frame 230, the front side frame 240 and the connecting side frame 250 together surround the receiving slot 260. More specifically, in this embodiment, the long axis direction (such as the Y axis) of the main side frame 230 is parallel to the long axis direction (such as the Y axis) of the front side frame 240, and is orthogonal to the long axis direction (such as the X axis) of the bottom plate 101. The long axis direction (such as the X axis) of the connecting side frame 250 is parallel to the long axis direction (such as the X axis) of the bottom plate 101. The circuit side plate 300 is locked on one side of the connecting side frame 250 facing the storage slot 260, and these first card slots 280 are respectively formed on the inner wall surfaces 211 of the main frame module 220 (such as the main side frame 230 and the front side frame 240) facing each other. The main side frames 230 of these main frame modules 220 of these detachable expansion card assemblies 200 are directly connected to each other, or are integrated into one. However, the present invention is not limited to the above features.

FIG. 3A is a partial front view of the main side frame 230 of FIG. 2 and a continuous motion diagram of its engaging portion 410. FIG. 3B is a front view of the front side frame 240 of FIG. 2 and a continuous motion diagram of its engaging portion 410. FIG. 4 is an exploded view of the first expansion card module 400 of FIG. 2. As shown in FIG. 3A and FIG. 3B, the first expansion card module 400 can be understood to be installed in the main frame module 220 (such as the main side frame 230 and the front side frame 240) through the moving track of the engaging portion 410 on the first slot portion 280 in FIG. 3A and FIG. 3B, and the second expansion card module 500 can be understood to be installed in the main frame module 220 (such as the main side frame 230 and the front side frame 240) from the moving track of the engaging portion 410 on the second slot portion 290 in FIG. 3A and FIG. 3B.

For example, as shown in Figures 2, 3A and 3B, each first slot portion 280 includes a first channel 281 and a second channel 282. The first channel 281 is formed on the inner wall surface 211 of the main frame module 220 (such as the main side frame 230 and the front side frame 240) facing the storage groove 260, and the long axis direction (such as the Z axis) of the first channel 281 is parallel to the first straight line direction (such as the Z axis), and is orthogonal to the long axis direction (such as the Y axis) of the second channel 282. The first channel 281 is connected to the second channel 282 and the top 212 of the main frame module 220 respectively. The second channel 282 is formed on the inner wall surface 211 of the main frame module 220 (such as the main side frame 230 and the front side frame 240).

The main frame module 220 further has two second slots 290. These second slots 290 are located on the inner wall surface 211 of the main frame module 220 (such as the main side frame 230 and the front side frame 240) relative to each other, and each second slot 290 is located below one of the first slots 280, that is, the first slot 280 is closer to the top 212 of the main frame module 220 than the second slot 290. For example, the second slot 290 includes a third channel 291 and a fourth channel 292. The third channel 291 is formed on the inner wall surface 211 of the main frame module 220 (such as the main side frame 230 and the front side frame 240) facing the storage groove 260, and the fourth channel 292 is formed on the inner wall surface 211 of the main frame module 220 (such as the main side frame 230 and the front side frame 240) facing the storage groove 260. The third channel 291 is aligned with and connected to the first channel 281, and the third channel 291 is connected to the fourth channel 292, and the long axis direction (such as the Z axis) of the third channel 291 is parallel to the long axis direction (such as the Z axis) of the first channel 281, and is orthogonal to the long axis direction (such as the Y axis) of the fourth channel 292.

Since the second expansion card module 500 is substantially the same as the first expansion card module 400, the form of the engaging portions 410 on both sides of the first expansion card module 400 shown in FIG. 4 can be used to deduce the form of the engaging portions 510 on both sides of the second expansion card module 500.

Thus, as shown in FIG. 2, FIG. 3A and FIG. 3B, when the engaging portions 510 on both sides of the second expansion card module 500 enter the first channels 281 of the main side frame 230 and the front side frame 240 respectively, the second expansion card module 500 first moves downward from the top 212 of the main frame module 220 into the storage slot 260; then, the engaging portion 510 moves from the first channel 281 to the third channel 291 and the fourth channel 292 in sequence, so that the second expansion card module 500 can move horizontally along the second straight line direction (such as the Y axis) at a first height H1 to the card slot 320 corresponding to the circuit side board 300 below (FIG. 2).

Afterwards, as shown in FIG. 2, FIG. 3A and FIG. 3B, when the engaging portions 410 on both sides of the first expansion card module 400 enter the first channels 281 of the main side frame 230 and the front side frame 240 respectively, the first expansion card module 400 first moves downward from the top 212 of the main frame module 220 into the storage slot 260; then, the engaging portion 410 moves from the first channel 281 to the second channel 282, so that the first expansion card module 400 can move horizontally along the second straight line direction (such as the Y axis) at a second height H2 greater than the first height H1 to the card slot 320 corresponding to the upper circuit side board 300 (FIG. 2). At this time, the second expansion card module 500 and the first expansion card module 400 overlap each other.

FIG. 5 is an exploded view of the first expansion card module 400 in FIG. 2 from another viewing angle. As shown in FIG. 4 and FIG. 5, the first expansion card module 400 includes a first support frame 420, a second support frame 430, and an expansion card component 440. The expansion card component 440 is located between the first support frame 420 and the second support frame 430, and is fixedly connected to the first support frame 420 and the second support frame 430 respectively. The first support frame 420 is connected to a corresponding snap-fit portion 410 (e.g., a slide post), that is, the snap-fit portion 410 is fixed to a side of the first support frame 420 that is opposite to the expansion card component 440. The second support frame 430 is connected to another snap-fit portion 410 (e.g., a slide pin), that is, the snap-fit portion 410 is fixed to a side of the second support frame 430 that is opposite to the expansion card component 440.

In addition, the expansion card component 440 includes an expansion card body 441 (such as a GPU card or a PCIe card) and a bracket 443. The expansion card body 441 has a connection interface 442 (such as a gold finger) on one side, and the connection interface 442 is used to insert the card slot 320 of the circuit side panel 300. The bracket 443 is fixed to one end of the expansion card body 441 and is directly locked to the first support frame 420 through a screw 444, and the second support frame 430 is located at one end of the expansion card body 441 opposite to the bracket 443.

The first expansion card module 400 further includes a first connecting post 451 and a plurality of (e.g., two) second connecting posts 452. One end of the first connecting post 451 is fixedly connected to the second supporting frame 430, and the other end thereof is fixedly connected to the end surface of the expansion card component 440. The lengths of the first connecting post 451 and the second connecting post 452 are the same. The second supporting frame 430 includes a frame 431, a receiving groove 432, and a long opening 433. The frame 431 is connected to another engaging portion 410 (e.g., a sliding nail) on one side of the expansion card component 440. The receiving groove 432 is located on the frame 431. The long opening 433 is formed on one side of the frame 431 facing the expansion card element 440, connected to the receiving groove 432, and accommodates these second connecting posts 452. In other words, these second connecting posts 452 can be movably limited in the long opening 433. In this way, by replacing the first connecting posts 451 and the second connecting posts 452 of different lengths to fill the gap between the second supporting frame 430 and the expansion card element 440, the expansion card body 441 of different lengths can be matched.

However, the present invention is not limited to the number and shape of the connecting pillars. In other embodiments, there may be only one connecting pillar.

As shown in FIG. 3A and FIG. 4, the inner wall surface 211 of the main frame module 220 (such as the main side frame 230 and the front side frame 240) has one or more protrusions 213. The first expansion card module 400 further includes two boosters 460. These boosters 460 are respectively located on the first supporting frame 420 and the second supporting frame 430.

More specifically, each booster 460 includes a rotating disk 461, a pivoting portion 462, and a handle portion 466. The pivoting portion 462 is located on the rotating disk 461, and allows the rotating disk 461 to be rotatably connected to the first supporting frame 420 or the second supporting frame 430 of the first expansion card module 400. The outer edge 467 of the rotating disk 461 has a recessed portion 463, and the recessed portion 463 accommodates the protrusion 213. The handle portion 466 is located on the outer edge 467 of the rotating disk 461 for the user to grasp.

In addition, as shown in Figures 4 and 5, the first expansion card module 400 further includes a plurality of (e.g., two) lever-type plungers 470. These lever-type plungers 470 are respectively located on the first supporting frame 420 and the second supporting frame 430 of the first expansion card module 400, and each lever-type plunger 470 is retractably located in the through-hole 464 of the corresponding rotating disk 461.

FIG. 6A and FIG. 6B are respectively operation diagrams of the detachable expansion card assembly 200 of FIG. 1. As shown in FIG. 2 and FIG. 6A, for example, the lever plunger 470 includes a collar 471, a handle 472 and a boss 473. The collar 471 is located on the first support frame 420 (or the second support frame 430) and overlaps with the through-port 464. The boss 473 is retractably located in the collar 471. One end of the boss 473 is connected to the handle 472 outside the collar 471, and the other end can extend from the collar 471 through the through-port 464 into the stop hole 214 of the main frame module 220 (FIG. 3A and FIG. 3B). Therefore, when the handle 472 is rotated to be coaxial with the boss 473, the boss 473 moves with the handle 472 and retracts into the ring 471 (refer to area M in Figure 2). Conversely, when the handle 472 is rotated to be orthogonal to the boss 473, the boss 473 moves with the handle 472 and extends out of the ring 471 (refer to Figure 4).

Thus, when the user rotates the rotating plate 461 so that the through opening 464 overlaps the blocking hole 214, the user can extend the boss 473 of the lever-type plunger 470 into the blocking hole 214, thereby fixing the first expansion card module 400 on the main frame module 220. Conversely, when the user pushes the boss 473 of the lever-type plunger 470 out of the blocking hole 214, the rotating plate 461 can rotate relative to the main frame module 220, thereby allowing the first expansion card module 400 to move horizontally on the main frame module 220. Similarly, since the second expansion card module 500 is substantially the same as the first expansion card module 400, the second expansion card module 500 also has the aforementioned lever-type plunger 470, and therefore, the operation of the lever-type plunger 470 of the second expansion card module 500 will not be described in detail.

As shown in Figures 2 and 6B, when the user wants to remove the first expansion card module 400 in Figure 6A from the card slot 320, the user first withdraws the protrusion 473 of the lever-type plunger 470 in Figure 6A from the stop hole 214 (Figure 2); then, the user rotates the rotating plate 461 in Figure 6B in a counterclockwise direction C, so that the inner wall 465 of the recessed portion 463 squeezes the protrusion 213 of the main frame module 220, and the first expansion card module 400 can be pushed by the protrusion 213 and pulled out of the corresponding card slot 320 along a withdrawal direction (see arrow A). Conversely, the user can also let the booster 460 push the first expansion card module 400 into the card slot 320 in the opposite direction by the same principle, so it will not be repeated here.

In addition, as shown in FIG. 1, the server device 10 further includes a fan assembly 700, a motherboard module 190, a power module 120, and a heat source module 130. The fan assembly 700 is located in the accommodation space 110 and fixed to the side walls 102. Since the long axis direction (such as the Y axis) of the fan assembly 700 and the long axis direction (such as the X axis) of the bottom plate 101 are orthogonal to each other, the fan assembly 700 divides the accommodation space 110 into a front area 111 and a rear area 112. The front area 111 is located between the front end plate 103 and the fan assembly 700, and the rear area 112 is located between the rear end plate 104 and the fan assembly 700.

Thus, the detachable expansion card assembly 200 is located in the front area 111, the power module 120 is located between the rear end plate 104 and the fan assembly 700 (i.e., the rear area 112), and the motherboard module 190 is located in the rear area 112, electrically connected to the power module 120, and electrically connected to the first expansion card module 400 through the corresponding circuit side plate 300. The heat source module 130 is, for example, at least one central processing unit on the motherboard module 190. However, as long as the heat source module 130 is located in the rear area 112, the present invention is not limited to the type and position of the heat source module 130.

More specifically, in this embodiment, the fan assembly 700 is locked to the bottom plate 101 and the side walls 102. The fan assembly 700 includes a fan frame 710 and a plurality of fans 720 (for example, 6 fans). The fans 720 are sequentially arranged side by side in the fan frame 710 to send the heat energy of the expansion card modules (such as the first expansion card module 400 and the second expansion card module 500) to the rear end area 112, and send the heat energy of the motherboard module 190, the power module 120 and the heat source module 130 out of the chassis 100 from the rear end area 112.

Furthermore, the server device 10 further includes at least one interface card module 140. The interface card module 140 includes a riser card 141 (raiser card) and an interface card component 142 (such as a GPU card or a PCIe card). The riser card 141 is inserted into the motherboard module 190. The interface card component 142 is inserted into the riser card 141. In this way, in addition to the detachable expansion card assembly 200 in the front area 111, an additional number of expansion cards can be installed in the rear area 112.

In addition, the fixed frame 210 of the detachable expansion card assembly 200 is symmetrically arranged in the chassis 100. More specifically, the storage slots 260 of the fixed frames 210 of the detachable expansion card assemblies 200 are opposite to each other, so that a partition channel 270 is separated between the fixed frames 210 of the detachable expansion card assemblies 200. The partition channel 270 is directly connected to the fan assembly 700, and overlaps and connects a part of the number (such as 2 to 3) of fans (hereinafter referred to as channel fans 721) to provide heat dissipation air flow to the channel fans 721 and accommodate the wires of these expansion card modules (not shown in the figure).

The server device 10 further includes a first storage module 150 and a plurality of second storage modules 160. The first storage module 150 is located in the partition channel 270, and the first storage module 150 is connected to the front end plate 103 of the chassis 100 in the front area 111. These second storage modules 160 are respectively located in the front area 111, and are connected to the front end plate 103 of the chassis 100 and one of the side walls 102. The first storage module 150 and the second storage module 160 are electrically connected to the expansion card bodies 441 of these detachable expansion card assemblies 200 through the motherboard module 190, so as to provide the storage space required for the expansion card bodies 441 of these detachable expansion card assemblies 200 to operate.

It should be understood that since these expansion card modules (i.e., the first expansion card module 400 and the second expansion card module 500) of these detachable expansion card assemblies 200 generate higher heat energy than the first storage module 150 when in operation, the temperature of the airflow flowing in the partition channel 270 will be relatively lower than the temperature on both sides thereof. Therefore, the relatively low-temperature airflow in the partition channel 270 can be transported to the rear end area 112 by the channel fan 721, thereby providing a heat dissipation means for the objects in the rear end area 112.

FIG. 7A is a top view of a server device 11 of an embodiment of the present invention and a perspective view of an air guide cover 170 thereof. FIG. 7B is a partial schematic view of the air guide cover 170 viewed from direction D of FIG. 7A. As shown in FIG. 7A and FIG. 7B, the server device 11 of the present embodiment is substantially the same as the above-mentioned embodiment, and the difference is that in the present embodiment, the server device 11 further includes an air guide cover 170. The air guide cover 170 includes a cover body 171 and at least one guiding slope 173. The cover body 171 is located in the rear end area 112 and fixedly covers the heat source module 130 and a portion of the motherboard module 190, so that the heat source module 130 is accommodated therein. The guiding slope 173 is located in the air guide cover 170, and can effectively guide the relatively low-temperature airflow to the heat source module 130, thereby improving the heat dissipation efficiency of the heat source module 130. More specifically, one end of the cover body 171 is enlarged and directly shields and connects to the channel fan 721, and the other end faces or connects to the rear end plate 104 of the chassis 100. In this way, the air guide cover 170 can receive the relatively low-temperature airflow brought by the channel fan 721 and guide it to the heat source module 130, thereby sending the heat energy of the heat source module 130 out of the chassis 100 from the rear end plate 104.

In addition, a plurality of memory blocks 180 are configured on the motherboard module 190. The heat source module 130 is located between two of the memory blocks 180. Each memory block 180 includes a plurality of memories 181 arranged parallel to each other. One side of the cover 171 has an opening 172, so that one of the memory blocks 180 passes through the opening 172, so that the cover 171 does not limit the design appearance of the air guide cover 170 due to the existing configuration of the motherboard module 190.

FIG. 8 is a cross-sectional schematic diagram of a server device 12 of an embodiment of the present invention. As shown in FIG. 8, the server device 12 of the present embodiment is substantially the same as the above embodiment, except that the expansion card modules 600A of the detachable expansion card assemblies 200 are arranged in a staggered manner. More specifically, the expansion card modules 600A on the upper side of the detachable expansion card assemblies 200 are not arranged at the same height, but are located on different planes P1 and P2, and the expansion card modules 600B on the lower side are not arranged at the same height, but are located on different planes P3 and P4, respectively. In this way, since the expansion card modules 600A and 600B of these detachable expansion card assemblies 200 are arranged in an alternating manner, it is helpful to distinguish the wires of the expansion card modules 600A and 600B on different sides, so that they will not be entangled in the partition channel 270.

FIG. 9 is a partial schematic diagram of a server device 13 of an embodiment of the present invention. As shown in FIG. 9, the server device 13 of the present embodiment is substantially the same as the above-mentioned embodiment, except that the storage slots 260 of the fixing frame 210 of the detachable expansion card assemblies 200 face each other, so that the expansion card components 440 in the storage slots 260 face each other. In addition, the first storage modules 150 and the second storage modules 160 are located between the detachable expansion card assemblies 200, and the first storage modules 150 and the second storage modules 160 are parallel to each other in the front area 111. In this way, configuration specifications for different requirements can be provided.

Through the above-mentioned structures of each embodiment, the server device and its detachable expansion card assembly of the present invention can not only optimize the number of expansion cards that can be accommodated in the server device, but also enhance the installation convenience of these expansion cards, thereby increasing consumers' willingness to purchase and use.
