It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions of the present invention, not its entire structure.

[0042] like Figure 1-4As shown, this embodiment provides a radiator, which includes a uniform temperature heat pipe 100 and a fixing plate 200. The fixing plate 200 is used to fix the heating element. The fixing plate 200 includes a plate body 210 and a reinforcing beam 220. The plate body 210 is provided with a first accommodating groove 211. The uniform temperature heat pipe 100 extends along a first direction, and multiple uniform temperature heat pipes 100 are arranged in parallel along a second direction. Thus, the uniform temperature heat pipe 100 directly absorbs heat from the heating element and conducts it, which is beneficial to improving the thermal conductivity of the radiator. There are at least two first accommodating grooves 211, and reinforcing beams 220 are set between adjacent first accommodating grooves 211. The two ends of the reinforcing beams 220 are connected to the plate body 210, thereby increasing the structural strength of the fixed plate 200, and avoiding the fixed plate 200 being easily deformed under the external force of the heating element and other loads due to the setting of the first accommodating grooves 211, which is beneficial to ensure the fit between the heating element and the fixed plate 200 and the uniform temperature heat pipe 100, so as to ensure the heat dissipation efficiency of the radiator, and is beneficial to be suitable for larger-sized heating elements.

[0043] Optionally, the cross-section of the uniform temperature heat pipe 100 is square, so that two adjacent uniform temperature heat pipes 100 can be in face-to-face contact, improving the thermal conductivity between the uniform temperature heat pipes 100 and thereby improving the temperature uniformity at different locations of the uniform temperature heat pipe 100. At the same time, the end surface of the uniform temperature heat pipe 100 close to the heating element can be in face-to-face contact with the heating element. Compared with a uniform temperature heat pipe 100 with a circular or elliptical cross-section, the square cross-section uniform temperature heat pipe 100 has a larger contact area with the heating element, which is conducive to improving thermal conductivity efficiency.

[0044] like Figure 2 As shown, further, when the heating area of ​​the heating element is large, the plate body 210 is deformed when the heating element is only fixed at the four corners of the plate body 210, resulting in poor contact between the heating element and the uniform temperature heat pipe 100, affecting the thermal conductivity efficiency. In order to solve the above problem, in this embodiment, a mounting hole 230 is provided on the plate body 210 and the reinforcing beam 220, and the heating element is fixed on the mounting hole 230 by a fixing member. The plate body 210 is used to fix the periphery of the heating element, and the reinforcing beam 220 is fixed in the middle position of the heating element, which prevents the fixing plate 200 from being deformed, and is conducive to ensuring the fit between the heating element and the plate body 210 and the uniform temperature heat pipe 100, thereby ensuring the thermal conductivity efficiency. For example, the heating element can be fastened in the mounting hole 230 by a dead angle screw.

[0045] When the heating element is large, the overall weight of the radiator will increase accordingly. In order to reduce the weight of the radiator, a plurality of weight-reducing grooves 212 are provided on the plate body 210 .

[0046] Please continue to see Figure 1-Figure 4Optionally, the radiator further includes a heat conduction module 300 and a heat dissipation module 400. The heat conduction module 300 partially contacts the end face of the uniform temperature heat pipe 100 facing away from the heating element. The heat conduction module 300 includes multiple groups of heat conduction pipes 310, which are spaced apart along a first direction. The heat dissipation module 400 includes multiple groups of heat dissipation components 410, which are spaced apart between two adjacent groups of heat conduction pipes 310 along the first direction, and the side faces of the heat conduction pipes 310 are in contact with the heat dissipation components 410. The radiator conducts heat from the fixing plate 200 and the uniform temperature heat pipe 100 to the heat dissipation components 410 through the heat conduction pipes 310, and uses the heat dissipation components 410 for heat dissipation.

[0047] Specifically, the heat pipe 310 includes a first heat conducting portion, which extends along the second direction and contacts the uniform temperature heat pipe 100 and the fixing plate 200 to absorb heat from the uniform temperature heat pipe 100 and the fixing plate 200. The heat pipe 310 also includes a second heat conducting portion, which is connected to at least one end of the first heat conducting portion and extends along the third direction. The third heat conducting portion contacts the heat dissipation assembly 410 to transfer heat from the first heat conducting portion to the heat dissipation assembly 410 for dissipation. To increase the contact area between the heat pipe 310 and adjacent structures and improve the heat conduction effect, the cross-sectional shape of the first and second heat conducting portions is square.

[0048] Furthermore, the heat dissipation assembly 410 is provided with a second receiving groove 411 for accommodating the heat pipe 310. The outer peripheral surface of the heat pipe 310 contacts the inner wall of the second receiving groove 411, thereby increasing the contact area between the heat pipe 310 and the heat dissipation assembly 410, thereby improving heat conduction efficiency. Specifically, the second heat conduction portion of the heat pipe 310 is located in the second receiving groove 411. This second heat conduction portion increases the heat dissipation range of the heat sink in the third direction, thereby reducing the surface area of ​​the heat sink and the heating element, that is, reducing the area occupied by the heat sink and the heating element.

[0049] Optionally, the cross-section of the first heat-conducting portion is square, thereby increasing the contact area between the first heat-conducting portion and the uniform temperature heat pipe 100 and the fixing plate 200, thereby improving the heat conduction effect. Optionally, the cross-section of the second heat-conducting portion is square, which is conducive to increasing the contact area between the second heat-conducting portion and the heat dissipation component 410, thereby improving the heat conduction effect.

[0050] The heat dissipation assembly 410 includes a plurality of heat dissipation members 412, which are stacked along a third direction. The side surfaces of the heat pipe 310 are in contact with the heat dissipation members 412, and along the third direction, one end of the heat pipe 310 away from the fixed plate 200 protrudes from the other end of the heat dissipation member 412 away from the fixed plate 200, so that the ineffective portion of the heat pipe 310 that is reserved during processing and cannot conduct heat protrudes from the heat dissipation assembly 410, so as to avoid the increase in cost caused by setting the heat dissipation member 412 in the ineffective portion of the heat pipe 310, which is conducive to reducing costs.

[0051] As an optional solution, heat sink assembly 410 can be continuously stamped, which facilitates a thin-walled structure and reduces the weight of the radiator. The wall thickness of heat sink 412 is 0.2mm-0.5mm. Optionally, heat sink assembly 410 formed by stacking multiple heat sinks 412 includes heat sink fins arranged parallel and spaced along the third direction to ensure effective heat dissipation.

[0052] The heat dissipation assembly 410 also includes a splicing portion 413, which is arranged at one end of the multiple heat dissipation elements 412 away from the fixed plate 200, and the portion of the heat pipe 310 protruding from the heat dissipation element 412 contacts the splicing portion 413 to fill the gap formed by the protruding portion of the heat pipe 310. The splicing portion 413 has a simple structure, which is conducive to reducing costs.

[0053] The radiator includes a heat dissipation module 400 and a mounting frame 500 connected to an end of the heat dissipation module 400 away from the heating element. The mounting frame 500 is configured to mount and fix the heat dissipation module 400. Specifically, the mounting frame 500 is fixed on the splicing portion 413.

[0054] Optionally, the mounting bracket 500 includes a main body 510 and two wings 520. The main body 510 is connected to the end of the heat dissipation module 400 facing away from the heating element. The connection here can be fixed by welding or connected by screws, etc. The two wings 520 are connected to both sides of the main body 510, and the wings 520 are provided with fixing holes to facilitate fixing the radiator as a whole to other structures. For example, the mounting bracket 500 as a whole can be formed by bending aluminum sheets, and the main body 510 is welded to the end face of the heat pipe 310. The main body 510 can also be welded to the end face of the splicing part 413 to achieve the fixation of the main body 510 to the heat dissipation module 400 and the heat conduction module 300.
