[0002] At present, when using a heat exchanger such as a heat spreader and a heat pipe for integrated heat dissipation or temperature equalization, the purpose of rapid heat conduction is achieved mainly by connecting the heat spreader and the heat pipe internally to each other and 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 changes from the vapor phase to the liquid phase due to cooling, the working fluid that has returned to the liquid state needs to flow back through structures such as capillary tissues, so as to achieve the aforementioned circulation effect.

[0042] In order to further disclose the features and technical contents of the present application, please refer to the following detailed description and drawings of the present application. However, the attached drawings are only provided for reference and illustration and are not intended to limit the present application.
[0043] See also Figure 1 and Figure 2 , are respectively a three-dimensional appearance schematic diagram and a three-dimensional exploded schematic diagram of the present application. The present application 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:
[0044] The temperature plate 1 comprises a lower plate 10 and an upper plate 11 which are overlapped in an upper and lower manner, and a hollow shape is formed between the lower plate 10 and the upper plate 11. Figure 4 or Figure 5 As shown, as long as one of the lower plate 10 and the upper plate 11 is formed into a concave shape, the interior of the plate 10 and the upper plate 11 can be formed into the hollow shape after the plate 10 and the upper plate 11 are covered. For example, in the present application, the lower plate 10 is formed into the concave shape, and the upper plate 11 is flat. Of course, the opposite arrangement can also be made, or the lower plate 10 and the upper plate 11 are both formed into the concave shape and covered with each other. In addition, Figure 4 or Figure 5 As shown, the temperature homogenizing plate 1 is provided with a capillary layer 100 at least in the lower plate 10 , and the capillary layer 100 can be formed by a metal mesh, powder sintering or grooves.
[0045] like Figure 3 As shown, 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 above 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 outward from the open end 201 of the tube body 20. 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 may be integrally formed (i.e., Figure 5 or Figure 6 When the capillary materials are different (ie, "different"), the extension portion 210 and the expansion portion 211 may be connected to each other in contact (ie, as shown); Figure 7 shown).
[0046] Please see again Figure 2 As shown, at least one through hole 110 is provided on the upper plate 11 of the above-mentioned temperature equalizing plate 1, and the through hole 110 is used for the above-mentioned heat pipe 2 to be inserted and fixed, and is set according to the number of heat pipes 2 to be configured, or according to the number of positions where the heat pipes 2 penetrate the temperature equalizing plate 1 (i.e., the number of opening ends 201); for example, in the embodiment given in the present application, 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".
[0047] like Figure 4 and Figure 5As shown, 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 with the capillary layer 100 through the expansion portion 211. In particular, each heat pipe 2 can be The expansion portion 211 of the capillary structure 21 is pressed onto the capillary layer 100 by the open end 201 of the tube body 20, so that the radially expanded expansion portion 211 can contact the capillary layer 100 with a larger contact area. In this way, the capillary transmission between the capillary layer 100 and the capillary structure 21 can be stably maintained and uninterrupted to ensure a good reflux effect of the liquid working fluid, and each heat pipe 2 is vertically arranged on the temperature equalizing plate 1.
[0048] 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. Figure 5 As shown, in one embodiment of the present application, the first through hole portion 202 can be a notch formed by a partial depression of the opening end 201, and the second through hole portion 212 is also a corresponding notch; and as shown in FIG. Figure 6 As shown, in another embodiment of the present application, the first through hole portion 202 is a broken hole near the opening end 201, and the second through hole portion 212 is also a corresponding broken hole. In this way, the interior of the temperature vapor chamber 1 and the interior of each heat pipe 2 can be maintained in a connected state through the first through hole portion 202 and the second through hole portion 212. Figure 8 and Fig. 9 As shown, in another embodiment of the present application, the lower edge 201a of the open end 201 of the tube body 20 can also be in contact with 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 with 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 provided between the open end 201 of the tube body 20 and the capillary layer 100.
[0049] Therefore, by means of the above-mentioned structural composition, the temperature-averaging device with heat pipe of the present application can be obtained.
[0050] However, the above description is only a preferred feasible embodiment of the present application, and does not limit the patent scope of the present application. Therefore, all equivalent structural changes made using the contents of the present application specification and drawings are also included in the scope of the present application and are hereby stated.
