Description

Temperature equalizing device with heat pipe

This invention relates to a heat transfer element, in particular to a temperature equalizing device with a heat pipe that connects a heat pipe with a temperature equalizing plate.

At present, when a heat exchanger such as a heat spreader and a heat pipe is used for heat dissipation or temperature equalization, the purpose of rapid heat conduction is achieved by connecting the heat spreader and the heat pipe internally and then performing a vapor-liquid phase change of the sealed working fluid inside. During the process of the vapor-liquid phase change and its circulation of the working fluid, when the working fluid is cooled and changes from the vapor phase back to the liquid phase, the working fluid that has returned to the liquid state needs to circulate through structures such as capillary tissues, so as to achieve the aforementioned circulation effect.

However, in the existing heat exchangers that integrate the above-mentioned temperature evaporating plate and heat pipe, in order to maintain the setting of the heat pipe, the tube body is usually pressed against the shell or capillary structure in the temperature evaporating plate after being inserted into the temperature evaporating plate. Therefore, the contact area between the capillary structure inside the heat pipe and the capillary structure inside the temperature evaporating plate is extremely small, making it difficult to provide a better reflux effect.

In view of this, the author of this invention has devoted himself to research and applied theory in order to improve and solve the above-mentioned deficiencies, and finally proposed a creation that is reasonably designed and effectively improves the above-mentioned deficiencies.

The main purpose of this invention is to provide a temperature equalizing device with a heat pipe, which can increase the contact area between the temperature equalizing plate and the capillaries inside the heat pipe, and maintain the connection between the temperature equalizing plate and the inside of the heat pipe to ensure that the liquid working fluid can have a good reflux effect.

In order to achieve the above-mentioned purpose, the invention provides a temperature equalizing device with a heat pipe, including a temperature equalizing plate and at least one heat pipe; the temperature equalizing plate includes a lower plate and an upper plate which are overlapped and covered with each other, and a hollow is formed between the lower plate and the upper plate, a capillary layer is provided in the lower plate, and at least one through hole is provided on the upper plate; the heat pipe includes a tube body passing through the through hole, and a capillary structure provided on the tube body, and one end of the tube body The heat pipe has a closed end outside the temperature equalizing plate and an open end inside the temperature equalizing plate at the other end, and the capillary structure has an extension portion and an expansion portion, the extension portion is attached to the inside of the tube body, and the expansion portion is radially expanded outward from the open end of the tube body; wherein the open end of the tube body of the heat pipe is in contact with the capillary layer inside the temperature equalizing plate by the expansion portion of the capillary structure, so that the expansion portion is between the open end of the tube body and the capillary layer.

In order to further reveal the features and technical content of this creation, please refer to the following detailed description and drawings of this creation. However, the attached drawings are only provided for reference and explanation, and are not used to limit this creation.

Please refer to Figures 1 and 2, which are respectively a three-dimensional appearance schematic diagram and a three-dimensional exploded schematic diagram of the present invention. The present invention provides a temperature equalization device with a heat pipe, comprising a temperature equalization plate 1, and at least one heat pipe 2 vertically arranged on the temperature equalization plate 1; wherein:

The temperature-averaging plate 1 comprises a lower plate 10 and an upper plate 11 which are overlapped and covered in an upper and lower manner, and a hollow shape is formed between the lower plate 10 and the upper plate 11. Specifically, as shown in FIG. 4 or FIG. 5, as long as one of the lower plate 10 and the upper plate 11 forms a concave shape, the inner part of the covered plate 10 can form the hollow shape; for example, in the invention, the lower plate 10 forms the concave shape, and the upper plate 11 is flat, but of course, the opposite arrangement can also be made, or the lower plate 10 and the upper plate 11 both form the concave shape and cover each other. In addition, as shown in FIG. 4 or FIG. 5 , the temperature-averaging plate 1 is provided with a capillary layer 100 at least in the lower plate 10 , and the capillary layer 100 may be formed by a metal mesh, powder sintering or a groove.

As shown in FIG. 3 , each of the heat pipes 2 includes a tube body 20 and a capillary structure 21 disposed in the tube body 20. The capillary structure 21 may also be formed of a metal mesh, powder sintering, or a combination of the aforementioned materials. One end of the tube body 20 has a closed end 200 located outside the temperature equalizing plate 1, and the other end is an open end 201 located inside the temperature equalizing plate 1. The capillary structure 21 has at least one extension portion 210 and an expansion portion 211 that are in contact with each other and connected, or are integrally formed. The extension portion 210 is attached to the tube body 20, and the expansion portion 211 is radially expanded from the open end 201 of the tube body 20 to the outside. When the extension portion 210 and the expansion portion 211 are made of the same capillary material, the extension portion 210 and the expansion portion 211 can be integrally formed (as shown in FIG. 5 or FIG. 6 ); and when they are made of different (i.e. “different”) capillary materials, the extension portion 210 and the expansion portion 211 can be connected to each other by contacting each other (i.e. as shown in FIG. 7 ).

Please refer to FIG. 2 , the upper plate 11 of the temperature equalizing plate 1 is provided with at least one through hole 110, and the through hole 110 is used for the heat pipe 2 to be inserted and fixed therein, and is provided depending on the number of heat pipes 2 to be configured, or the number of positions (i.e., the number of opening ends 201) at which the heat pipes 2 penetrate into the temperature equalizing plate 1; for example, in the embodiment of the present invention, the number of heat pipes 2 configured on the temperature equalizing plate 1 is "three", so the number of the through holes 110 also corresponds to "three".

As shown in FIG. 4 and FIG. 5 , the tube body 20 of each heat pipe 2 extends into the interior of the temperature averaging plate 1 through the corresponding through hole 110 with its open end 201, so that the expansion portion 211 of the capillary structure 21 abuts against the capillary layer 100 in the temperature averaging plate 1, so that the expansion portion 211 can be between the open end 201 of the tube body 20 and the capillary layer 100, and the extension portion 210 of the capillary structure 21 can overlap and contact the capillary layer 100 through the expansion portion 211, especially each heat pipe 2 The expanded portion 211 of the capillary structure 21 can be pressed onto the capillary layer 100 through the open end 201 of the tube body 20, so that the radially expanded expanded portion 211 can contact the capillary layer 100 with a larger contact area. In this way, the capillary layer 100 and the capillary structure 21 can be stably connected and uninterrupted in capillary transmission to ensure a good reflux effect of the liquid working fluid, and each heat pipe 2 can be vertically arranged on the temperature equalizing plate 1 to ensure stability.

Furthermore, the tube body 20 of each heat pipe is provided with a first through hole portion 202 near its open end 201, and a second through hole portion 212 corresponding to the first through hole portion 202 is provided on the capillary structure 21, so that the interior of the tube body 20 and the interior of the temperature equalizing plate 1 can be connected to each other through the first through hole portion 202 and the second through hole portion 212. As shown in FIG5, in one embodiment of the present invention, the first through hole portion 202 can be a notch formed by a partial depression of the open end 201, and the second through hole portion 212 is also a corresponding notch; and as shown in FIG6, in another embodiment of the present invention, the first through hole portion 202 is a broken hole near the open end 201, and the second through hole portion 212 is also a corresponding broken hole. Thereby, the interior of the temperature equalizing plate 1 and the interior of each heat pipe 2 can be kept in communication through the first through-hole portion 202 and the second through-hole portion 212 . As shown in Figures 8 and 9, in another embodiment of the present invention, the lower edge 201a of the open end 201 of the tube body 20 can also be connected to the expansion portion 211 of the capillary tissue 21, so that the expansion portion 211 can extend from the lower edge 201a of the open end 201, and the second through hole portion 212 is provided on the expansion portion 211 to connect the open end 201. In this way, the open end 201 of the tube body 20 does not need to be provided with the aforementioned first through hole portion 202, and at the same time, the expansion portion 211 of the capillary tissue 21 can still be located between the open end 201 of the tube body 20 and the capillary layer 100.

Therefore, through the above-mentioned structural composition, the temperature-averaging device with heat pipe of the present invention can be obtained.
