Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation, in particular to a hollow one-outlet multi-channel structure. Background Art

[0002] In the prior art, a water-cooled heat dissipation cold plate is arranged at the position of the heating element, and a circulation channel for the circulation of heat exchange medium is also arranged at the position where the heat dissipation cold plate is arranged at the position where the heating element is arranged. When in use, the heat exchange medium in the circulation channel is used to take away the heat to achieve the heat dissipation of the heating element. Since the water source inlet is located on one side of the heat dissipation cold plate, in order to achieve a faster heat dissipation effect and ensure uniform heat dissipation at various positions of the heating element, a branch channel structure is adopted in the prior art, including a direct flow channel and multiple water outlets arranged along the extension direction of the direct flow channel, and all the water outlets are connected to the circulation channel.

[0003] The applicant has found that the prior art has at least the following technical problems:

[0004] One end of the direct flow channel in the existing branch channel structure is connected to the water source. After the heat exchange medium enters through one end of the direct flow channel, it flows out through the water outlet in sequence and enters the circulating flow channel. This structure makes the process of the heat exchange medium entering the circulating flow channel longer and the flow rate is slow. Moreover, it cannot be quickly transported to different positions of the heating element, and can only slowly exchange heat from one side of the heating element to the other side, resulting in uneven heat exchange and affecting the heat dissipation effect. Utility Model Content

[0005] The utility model aims to provide a hollow multi-channel structure to solve the technical problems of slow flow diversion, slow flow rate, uneven heat dissipation and poor heat dissipation effect in the diversion channel structure in the prior art.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] As a further improvement of the utility model, the branch channel is in a curved structure, including a large-mouth confluence section, a transfer section and a small-mouth acceleration section which are arranged in sequence.

[0009] As a further improvement of the utility model, the large-mouth confluence section is in a trumpet shape, the large end of the large-mouth confluence section is connected to the water inlet channel, and the small end of the large-mouth confluence section is connected to the transfer section.

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0021] like Figure 1 As shown, the utility model provides a hollow one-outlet multi-channel structure, which is arranged in the heat sink and is used to connect the water source and the circulation channel. It should be noted here that the circulation channel is located on the side where the heat sink and the heating element are in contact. The hollow one-outlet multi-channel structure not only realizes the connection between the water source and the circulation channel and the medium diversion, but also enables the heat exchange medium to quickly reach the circulation channel position in contact with the heating element, which can be closer to the heating element, so that the heat dissipation effect is better and the heat dissipation is more uniform.

[0022] Specifically, in this embodiment, the hollow one-outlet multi-channel structure is a one-inlet multi-outlet structure, including a water inlet channel 1 and a plurality of branch channels 2; all the branch channels 2 are symmetrically arranged with the central axis of the water inlet channel 1 as the center.

[0023] It should be noted here that the number of branch channels 2 can be set according to the number of heating elements or the area of ​​the heating elements. In short, the branch channels 2 are provided to quickly transport the heat exchange medium to the heating element position.

[0024] As a further improvement of the utility model, the branch channel 2 has a curved structure, which can lead the heat exchange medium in the water inlet channel 1 at the center obliquely outward and finally input it vertically into the circulation channel. Furthermore, the branch channel 2 includes a large-mouth confluence section 21, a transfer section 22 and a small-mouth acceleration section 23 arranged in sequence.

[0025] The large-mouth confluence section 21 is used to divert and converge the heat exchange medium. The function of diversion is to transport the heat exchange medium to different areas of the heating element, and the purpose of convergence is to increase the flow rate of the heat exchange medium to improve the heat exchange effect; the transfer section 22 is used to change the diversion direction from outward to downward; the small-mouth acceleration section 23 is the final medium acceleration to form a rapid transportation effect, which not only increases the circulation speed and the heat exchange effect, but also utilizes the rapid flow of the medium to cause certain medium fluctuations, thereby improving the heat exchange effect between the media.

[0026] like Figure 1As shown, the large-mouth confluence section 21 is in a trumpet shape, the large end of the large-mouth confluence section 21 is connected to the water inlet channel 1, and the small end of the large-mouth confluence section 21 is connected to the transfer section 22; the transfer section 22 is a trumpet-shaped curved arc structure, the large end of the transfer section 22 is connected to the large-mouth confluence section 21, and the small end of the transfer section 22 is connected to the small-mouth acceleration section 23, and the small-mouth acceleration section 23 is a cylindrical structure of equal diameter.

[0027] Taking into account the area size of the heating element and the distance relationship between different heating elements, the bending angle of the transfer section 22 is 90°-180°, which can be selected and set according to actual conditions.

[0028] In an optional embodiment of the present invention, the number of branch channels 2 is nine, which are arranged in three rows, with three branch channels 2 in each row; the central axis of the branch channel 2 in the middle row and the central axis of the water inlet channel 1 are located in the same plane.

[0029] Furthermore, the central axis of a branch channel 2 located in the middle of the middle row coincides with the central axis of the water inlet channel 1 .

[0030] Furthermore, the joints between the water inlet channel 1 and all the branch channels 2, as well as the turning points of the branch channels 2, are all blunt-angle arc transition structures. This structural setting is adopted to further reduce the pipeline resistance when the medium flows.

[0031] It should be noted here that Figure 1 Only the structure of one embodiment is illustrated. Considering the actual needs, the number of branch channels 2 may not be 9, for example, 2 to 8, or 10 or more may be provided. There is no specific limitation on the number of settings here.

[0032] The hollow one-outlet multi-channel structure provided by the utility model has a one-inlet and multiple-outlet structure, and multiple branch channels 2 are symmetrically arranged with the water inlet channel 1 as the center. Through this structural arrangement, the heat exchange medium entering through the water inlet channel 1 can be quickly diverted to different areas of the circulation channel, so that different areas of the heating element can be quickly dissipated. In addition, this structural arrangement can also reduce the flow channel resistance, increase the flow rate, make the heat dissipation of the heating element more uniform, and improve the heat dissipation effect.
