As a necessary energy source in life, electric energy is used in all aspects of life. In order to ensure the normal supply of electric energy, various power generation methods are generally used to generate electricity.

In related technologies, thermal power and other methods are generally used to generate electricity. However, thermal power generation consumes resources such as coal mines and also causes pollution to the environment.

Based on this, as shown in Figure 1, this application provides a power generation system 1 that utilizes waste heat from underwater servers, which includes a box 11, a heating component 12, a heating cabin 13, a Stirling engine 14, a rotating member 15 and Generator16. The box 11 is placed in the water, and the box 11 has an accommodation cavity 11A inside. The heating element 12 is disposed in the accommodation cavity 11A. The heating chamber 13 has a heating cavity 13B inside. The heating cavity 13B is used to accommodate liquid. For example, the liquid can be water. The heat generated by the heating element 12 can be conducted to the liquid in the heating cavity 13B. The hot end of the Stirling engine 14 extends into the heating chamber 13, and the cold end of the Stirling engine 14 is used to be in contact with water. The rotating member 15 is connected to a Stirling engine 14, and the Stirling engine 14 is used to drive the rotating member 15 to rotate. The rotating member 15 is drivingly connected to the input shaft of the generator 16 and is used to drive the input shaft of the generator 16 to rotate.

Through the above arrangement, since the heat generated by the heating element 12 can be conducted to the liquid in the heating chamber 13, the temperature of the liquid in the heating chamber 13 can be increased. Since the hot end of the Stirling engine 14 extends into the heating chamber 13 and the cold end of the Stirling engine 14 is located in the water, the Stirling engine 14 can use the temperature difference to drive the rotating member 15 to rotate. Since the rotating member 15 interacts with the power generation The generator 16 is connected in a transmission manner, so the rotating member 15 can drive the generator 16 to rotate, thereby generating electricity.

Since the generator 16 is driven by the Stirling engine 14, and the Stirling engine 14 uses the waste heat generated by the heating element 12 as a heat source and external water as a cold source to achieve rotation, it can save energy. while avoiding environmental pollution.

And since the heat generated by the heating component 12 is absorbed by the hot end of the Stirling engine 14, the heat dissipation of the heating component 12 can be achieved.

It can be understood that the above-mentioned box 11 can be installed in river water or sea water. In this way, natural cold sources can be used to cool the cold end of the Stirling engine 14 to save energy.

Among them, the heating cabin 13 may have a regular shape such as a rectangular parallelepiped shape or a cube shape, or the heating cabin 13 may also have an irregular shape.

In addition, the above-mentioned heating component 12 may be a server in a data center. Alternatively, it can also be any other suitable device capable of dissipating heat.

In some examples, in order to facilitate the transfer of heat in the liquid in the heating chamber 13 to the hot end of the Stirling engine 14 , the hot end of the Stirling engine 14 can be immersed in the liquid in the heating chamber 13 . In this way, the hot end of the Stirling engine 14 can directly absorb the heat in the liquid through contact with the liquid. This can ensure the heat absorption efficiency of the Stirling engine 14, thereby ensuring the power generation efficiency of the generator 16.

It can be understood that the above-mentioned Stirling engine 14 may be any one of alpha (α) type, beta (β) type, and gamma (γ) type.

In some examples, an α-type Stirling engine 14 is provided below. Specifically, as shown in FIG. 2 , the above-mentioned rotating member 15 includes a rotating part 151 , a first crankshaft part 152 and a second crankshaft part 153 . The first crankshaft part 152 and the second crankshaft part 153 are spaced apart along the rotation axis of the rotating part 151, and the first crankshaft part 152 and the second crankshaft part 153 are The crankshaft portions 153 are arranged at intervals around the rotation axis of the rotation portion 151 , and both the first crankshaft portion 152 and the second crankshaft portion 153 are arranged eccentrically to the rotation axis of the rotation portion 151 .

Please continue to refer to FIG. 2 . The above-mentioned Stirling engine 14 includes a first cylinder 141 , a first piston 142 , a second cylinder 143 , a second piston 144 , a connecting pipe 145 , a first connecting rod 146 and a second connecting rod 147 .

The first cylinder 141 has a first cavity 141A inside. The position of the first cavity 141A on the first cylinder 141 constitutes the hot end of the Stirling engine 14. The first cylinder 141 is provided with a cavity connected to the first cavity. 141A communicates with the first through hole 141B, the first cylinder 141 partially extends into the heating chamber 13, and the first cavity 141A is located in the heating chamber 13, so that the heat in the liquid in the heating chamber 13 is conducted to the first cavity 141A, thereby heating the gas in the first cavity 141A. The first piston 142 at least partially extends into the first cavity 141A through the first through hole 141B, and the first piston 142 is sealed with the inner wall of the first through hole 141B.

The second cylinder 143 has a second cavity 143A inside. The position of the second cavity 143A on the second cylinder 143 forms the cold end of the Stirling engine 14. The second cylinder 143 is provided with a second cavity 143A. The second through hole 143B communicates with the second through hole 143A, and the second cylinder 143 is partially extended into the water to use water to cool down the gas in the second cavity 143A. The second piston 144 at least partially extends into the second cavity 143A through the second through hole 143B, and the second piston 144 is sealed with the inner wall of the second through hole 143B. One end of the connecting tube 145 is connected to the first cavity 141A, and the other end is connected to the second cavity 143A. The first end of the first connecting rod 146 is hingedly connected to the first piston 142 through the first through hole 141B. The first end of the second connecting rod 147 is hingedly connected to the second piston 144 through the second through hole 143B. The second end of the first connecting rod 146 is hinged to the first crankshaft portion 152 at a first point, and the second end of the second connecting rod 147 is hinged to the second crankshaft portion 153 at a second point.

For example, the first crankshaft part 152 and the second crankshaft part 153 are arranged at intervals of 90° around the rotation axis of the rotation part 151 .

It should be explained that in order to ensure the smooth start of the above-mentioned Stirling engine 14, the power generation system 1 using waste heat of underwater servers provided by this application also includes a motor, and the motor is drivingly connected to the rotating member 15. The motor is used to give the rotating member 15 an initial amount of rotation, so that the rotating member 15 starts to rotate. Then the motor stops rotating, and then the Stirling engine 14 runs by itself to drive the rotating member 15 to rotate.

Through the above settings, as shown in FIGS. 3 to 6 , the Stirling engine 14 will go through four processes to drive the rotating part 151 to rotate.

As shown in Figure 3, the Stirling engine 14 is in the first state (initial state). At this time, a force in the Y direction is applied to the rotating part 151, causing the rotating part 151 to rotate in the Y direction, thus driving the second piston 144 to Move downward to compress the low-temperature gas in the second cavity 143A into the first cavity 141A through the connecting pipe 145, so that the first piston 142 moves upward until it moves to the state shown in Figure 4 (the rotating part 151 movement first quarter).

Second state: Since the first cylinder 141 extends into the heating chamber 13B, under the heating of the liquid in the heating chamber 13B, the gas in the first chamber 141A is heated and expands, so that the first chamber 141A and the second The air pressure in the cavity 143A increases to drive both the first piston 142 and the second piston 144 to move upward. Until it moves to the state shown in Figure 5 (the rotating part 151 moves for the second quarter).

Third state: Since the rotating part 151 has inertia, the rotating part 151 will rotate in the Y direction again under the action of the inertia of the rotating part 151 . And drive the first piston 142 to move downward, and the second piston 144 to move upward. At this time, the gas in the first cavity 141A enters the second cavity 143A through the connecting pipe 145 until it moves to the state shown in Figure 6 (The rotating part 151 moves the third quarter).

Fourth state: Since the second cylinder 143 extends into the water, under the cooling effect of the water, the gas in the second cavity 143A shrinks when cooled, thereby increasing the air pressure in the first cavity 141A and the second cavity 143A. Descend to drive both the first piston 142 and the second piston 144 to move downward until they move to the state shown in Figure 3 (the rotating part 151 moves the fourth quarter).

At this point, the Stirling engine 14 drives the rotating part 151 to complete one circle of motion through the above process. And the above action is repeated to drive the rotating part 151 to keep moving. As a result, the rotating part 151 is continuously driven to rotate, and the generator 16 is further driven to rotate to achieve power generation.

It can be understood that the gas contained in the first cavity 141A and the second cavity 143A may be hydrogen, helium and other gases with small specific heat capacities. Of course, it can also contain air.

On this basis, since the heating cabin 13 is located in the water, in order to facilitate the installation of the Stirling engine 14, the generator 16, the rotating member 15, etc., as shown in Figure 7, the above-mentioned power generation system 1 using the waste heat of the underwater server also includes The sealed cabin 17 is arranged in the water. The generator 16 and the rotating member 15 are both arranged in the sealed cabin 17. The Stirling engine 14 is partially located in the sealed cabin 17, and the hot end of the Stirling engine 14 passes through the seal. The side wall of the cabin 17 extends into the heating cabin 13, and the cold end of the Stirling engine 14 extends through the side wall of the sealed cabin 17 into the water outside the sealed cabin 17.

It can be understood that the sealed cabin 17 is a closed space that can prevent external water from entering.

In this way, the sealed cabin 17 provides a sealed space for the Stirling engine 14, the generator 16 and the rotating parts 15, which can avoid the influence of water on the Stirling engine 14, the generator 16 and the rotating parts 15, thereby ensuring Normal power generation.

In addition, since the sealed cabin 17 and the heating cabin 13 are both arranged in the water, the position of the sealed cabin 17 in the water can be adjusted so that the hot end of the Stirling engine 14 in the sealed cabin 17 extends into the heating cabin 13. This facilitates the layout setting of the Stirling engine 14 and the heating cabin 13 .

In some embodiments, as shown in FIG. 8 , the power generation system 1 using waste heat of underwater servers provided by this application also includes an above-water platform 18 , and the above-water platform 18 is disposed on the water.

By setting up the above-water platform 18, it is convenient for the operator to monitor the underwater heating components 12, Stirling engine 14 and other equipment, thereby ensuring the normal operation of the underwater equipment.

Among them, in order to enable the above-water platform 18 to be on the water surface, multiple support columns may be provided at the bottom of the above-water platform 18 so that one end of the support columns is connected to the bottom of the above-water platform 18 and the other end of the support columns is connected to the bottom of the water. This allows the water platform 18 to float above the water.

Alternatively, in order to enable the above-water platform 18 to be located on the water surface, the above-water platform 18 may also be provided with a suspended material, so that the above-water platform 18 is directly suspended on the water surface.

In some examples, as shown in Figure 8, the power generation system 1 for utilizing underwater server waste heat provided by this application also includes a cable 19. One end of the cable 19 is electrically connected to the electrical equipment or power storage equipment, and the other end of the cable 19 is electrically connected to the electrical equipment or power storage equipment. The generator 16 is electrically connected.

By arranging the cable 19, the electric energy generated by the generator 16 is transmitted to the electric equipment or electric storage equipment using the cable 19, so as to realize the transmission and utilization of electric energy.

Among them, the above-mentioned electric equipment and electric storage equipment can be installed on the water platform 18, or can also be installed on land.

In some embodiments, in order to enable the heat generated by the heating element 12 to be conducted to the heating cabin 13, as shown in FIG. 9, the above-mentioned box 11 includes a first heat-conducting wall plate 111. The heating cabin 13 includes a second heat conductive wall plate 131. The first heat conductive wall plate 111 is in contact with the second heat conductive wall plate 131. The heat generated by the heating component 12 can be conducted to the second heat conductive wall plate 131 through the first heat conductive wall plate 111. .

Through the above arrangement, the first heat-conducting wall plate 111 and the second heat-conducting wall plate 131 can be used as heat-conducting media. When the heating component 12 dissipates heat, the heat will be dissipated into the air in the accommodation cavity 11A, and then conducted to the first heat-conducting wall. on the plate 111 , and then transmitted to the second heat conductive wall plate 131 through the first heat conductive wall plate 111 , and then enters the heating chamber 13 to heat the liquid in the heating chamber 13 .

For example, the materials of the first thermally conductive wall plate 111 and the second thermally conductive wall plate 131 may include copper, aluminum, etc. Copper and aluminum have better thermal conductivity and are cheaper.

In this case, the wall panels of the heating chamber 13 except the second heat conductive wall panel 131 are set as insulation wall panels. This can avoid the heat loss in the water in the heating chamber 13 and allow more heat to pass through the first heat conductive wall panel. The wall plate 111 and the second heat-conducting wall plate 131 enter the heating chamber 13B, and are then absorbed by the hot end of the Stirling engine 14, thereby improving the utilization rate of heat.

In some examples, in order to ensure that the first heat conductive wall plate 111 and the second heat conductive wall plate 131 have sufficient contact area, the first heat conductive wall plate 111 and the second heat conductive wall plate 131 can be made to face each other, so that the first heat conductive wall plate 111 and the second heat conductive wall plate 131 can be directly opposite each other. The contact area between the wall plate 111 and the second heat conductive wall plate 131 is the largest, thereby improving the heat conduction efficiency between the first heat conductive wall plate 111 and the second heat conductive wall plate 131 .

Of course, the first heat conductive wall plate 111 and the second heat conductive wall plate 131 may not be in complete contact.

For example, the first heat conductive wall plate 111 may be a flat plate as a whole, which can facilitate the processing of the first heat conductive wall plate 111 . Alternatively, the first thermally conductive wall plate 111 may also be a curved plate.

Similarly, the second heat conductive wall plate 131 can also be a straight plate, which can facilitate the processing of the second heat conductive wall plate 131 . Alternatively, the second heat conductive wall plate 131 may also be a curved plate.

In some embodiments, as shown in FIG. 9 , the second thermally conductive wall plate 131 is located above the first thermally conductive wall plate 111 . Since the hot air will rise, the heat generated by the heating component 12 will flow to the location of the first thermally conductive wall plate 111, which allows the first thermally conductive wall plate 111 to better absorb the heat generated by the heating component 12. Therefore, the heat on the first heat conductive wall plate 111 is better conducted to the second heat conductive wall plate 131 , which is more conducive to heating the water in the heating chamber 13 .

In some embodiments, as shown in Figure 10, the power generation system 1 utilizing underwater server waste heat provided by this application also includes a water inlet pipe 20 and a first pump body 21. The water inlet end of the water inlet pipe 20 is used to communicate with the water source. The water outlet end of the water inlet pipe 20 is connected with the heating chamber 13B. The first pump body 21 is used to drive the liquid in the water inlet pipe 20 into the heating chamber 13B.

In this way, when the temperature of the water in the heating chamber 13B is too high, the first pump body 21 is started to allow the external cold water to enter the heating chamber 13B to reduce the temperature of the water in the heating chamber 13B, so that the water in the heating chamber 13B is There is an appropriate temperature difference between the temperature of the water and the temperature in the accommodating cavity 11A to ensure that the heat in the accommodating cavity 11A can be smoothly transmitted to the second thermally conductive wall plate 131 through the first thermally conductive wall plate 111 and then to the heating cavity 13B. in the water inside. Thus, the heat dissipation efficiency of the heating component 12 is ensured.

For example, the water inlet end of the water inlet pipe 20 can be directly connected to the river water or sea water outside the box 11 , so that water can be obtained nearby and the installation of the water inlet pipe 20 can be facilitated.

In some examples, as shown in FIG. 10 , the power generation system 1 using waste heat of underwater servers provided by this application also includes a drainage pipe 22 and a valve 23 . The water inlet end of the drainage pipe 22 is connected with the heating chamber 13B, and the valve 23 is provided on the drainage pipe 22 for controlling the opening and closing of the water inlet pipe 20 .

Through the above arrangement, while the low-temperature water outside the heating chamber 13B is discharged into the heating chamber 13B, the valve 23 is controlled to be opened, so that the high-temperature water in the heating chamber 13B can be discharged through the drain pipe 22 to ensure that the heating chamber 13B has a limited amount of water. The water temperature inside can be adjusted infinitely within the space.

In order to prevent debris in seawater and river water from entering the heating chamber 13B, as shown in Figure 10, the power generation system 1 that utilizes the waste heat of underwater servers provided by this application also includes a first filter 24. The first filter 24 is disposed in the inlet. The water pipe 20 is used to filter the water entering the heating chamber 13B.

In this way, debris can be prevented from entering the heating chamber 13B through the water inlet pipe 20, thereby ensuring that the water in the heating chamber 13B remains clean, thereby preventing debris and the like from causing hardness to the heat absorption of the hot end of the Stirling engine 14, so that The heat in the liquid in the heating chamber 13B can be smoothly conducted to the hot end of the Stirling engine 14, thereby ensuring the heat absorption efficiency of the Stirling engine 14 and thereby ensuring the power generation efficiency of the generator 16.

On this basis, as shown in Figure 10, the above-mentioned power generation system 1 using waste heat of underwater servers also includes a first temperature sensor 25. The first temperature sensor 25 is used to detect the first actual temperature value in the heating cabin 13. The pump body 21 is turned on or off according to the first actual temperature value.

By setting the first temperature sensor 25, the temperature of the water in the heating chamber 13B can be monitored more accurately, so that the first pump body 21 can be started at the appropriate time to discharge the external low-temperature water into the heating chamber 13, so as to be more accurate. to regulate the water temperature in the heating chamber 13B. This ensures that the water temperature in the heating chamber 13B is within a suitable range to ensure the power generation efficiency of the Stirling engine 14 .

It can be understood that the opening and closing of the first pump body 21 can be controlled by the controller. Specifically, the first pump body 21 is electrically connected to the controller, and the first temperature sensor 25 is electrically connected to the controller, so that the controller controls the first pump according to the first actual temperature value detected by the first temperature sensor 25 body 21 starts or shuts down.

Alternatively, the first actual temperature value can also be read manually, and then the opening or closing of the first pump body 21 can be manually controlled.

In some examples, when the first actual temperature value is greater than or equal to the first preset temperature value, the first pump body 21 is started, and when the first actual temperature value is less than the first preset temperature value, the first pump body 21 is started. The pump body 21 is closed.

This can prevent the water temperature in the heating chamber 13B from being too low or too high to ensure that the first actual temperature value can not only meet the operation of the Stirling engine 14 but also meet the basic heat dissipation requirements of the heating element 12 .

For example, the first preset temperature may be between 50°C and 70°C, such as 50°C, 55°C, 60°C or 70°C. Of course, the first preset temperature can also be any other suitable value.

For example, the first temperature sensor 25 can be disposed in the heating chamber 13B to detect the temperature in the heating chamber 13B. Alternatively, the first temperature sensor 25 may be disposed outside the heating chamber 13B to detect the temperature outside the heating chamber 13B.

In some examples, when the application includes a drain pipe 22 and a valve 23, the valve 23 is electrically connected to the controller. When the controller controls the first pump body 21 to open, it also controls the valve 23 to open. When the controller controls the first pump body 21 to close, it also controls the valve 23 to close. In this way, the temperature of the water in the heating chamber 13B can be adjusted more intelligently.

In other examples, when the first pump body 21 is manually closed or started, the valve 23 can also be manually closed or opened.

Of course, the first pump body 21 can also be started after a preset time to adjust the temperature of the water in the heating chamber 13B through time setting.

For example, the preset time can be 1 day, 2 days, 5 days or 10 days, etc.

For example, the material of the first heat pipe 26 may include copper, aluminum, etc. Copper and aluminum have good thermal conductivity and are cheap.

In this case, the wall panel of the heating chamber 13 is set as an insulating wall panel, which can avoid the heat loss in the water in the heating chamber 13, thereby allowing more heat to be absorbed by the hot end of the Stirling engine 14 to improve the efficiency of the heating chamber.

At the same time, since the second heat conduction pipe 28 is made of a heat conductive material, the water flowing through the second heat conduction pipe 28 can dissipate heat through the wall of the second heat conduction pipe 28 , so that the water flowing back into the second heat conduction pipe 28 can The temperature is lowered to better dissipate heat from the heating component 12 .

For example, the material of the second heat pipe 28 may include copper, aluminum, etc. Copper and aluminum have good thermal conductivity and are cheap.

By arranging the second temperature sensor 29, the temperature of the water in the heating chamber 13B can be more accurately monitored, so that the second pump 27 can be started or closed at the appropriate time to regulate the water temperature in the heating chamber 13B. This ensures that the water temperature in the heating chamber 13B is within a suitable range to ensure the power generation efficiency of the Stirling engine 14 .
