[0037] Example 1

[0038] Combined with Figure 1-5 , this embodiment provides an inductor heat sink, including:

[0039] Liquid cooling plate 1;

[0040] A heat-conducting housing 2 connected to the liquid cooling plate 1, the heat-conducting housing 2 is used to accommodate the inductor body 3;

[0041] A heat-conducting insulating layer 5, one end of the heat-conducting insulating layer 5 is in contact with the inner wall of the heat-conducting housing 2, and the other end of the heat-conducting insulating layer 5 is used to contact with the inductor body 3;

[0042] The heat-conducting insulating layer 5 can preferably fill the entire gap between the inductor body 3 and the inner wall of the heat-conducting housing 2 .

[0043] Specifically, when dissipating heat, the heat generated by the inductor body 3 is transferred in sequence through the heat-conducting insulating layer 5, the heat-conducting housing 2 and the liquid cooling plate 1; the liquid cooling plate 1 is used to flow the cooling liquid, so as to facilitate the inductor body 3 to achieve liquid cooling and heat dissipation, and a PCB board 4 can also be installed on the side of the liquid cooling plate 1 away from the heat-conducting housing 2, the PCB board 4 and the inductor body 3 are electrically connected, the PCB board 4 plays a control role on the inductor body 3, and the liquid cooling plate 1 plays a heat dissipation role on the PCB board 4; the heat-conducting housing 2 is used to accommodate the inductor body 3, and specifically can be in the heat-conducting housing 2. A receiving cavity is provided in the housing, and the inductor body 3 is placed in the receiving cavity. The material of the heat-conducting housing 2 can be aluminum, copper or other materials with good thermal conductivity, preferably aluminum. The heat-conducting insulating layer 5 is used for heat conduction and insulation. The material of the heat-conducting insulating layer 5 can be soft materials such as thermally conductive silica gel and thermally conductive silicone grease. The soft material makes it easy for the heat-conducting insulating layer 5 and the outer surface of the inductor body 3 to have good contact tightness, which is equivalent to making the heat at various positions on the outer surface of the inductor body 3 effectively and evenly transferred through the heat-conducting insulating layer 5, thereby making the heat dissipation performance of the inductor body 3 good.

[0044] Further, such as Figure 3 , the heat-conducting housing 2 comprises:

[0045] The shell body 21 is used to accommodate the inductor body 3;

[0046] A base 22 connected to the shell body 21, the base 22 is connected to the liquid cooling plate 1;

[0047] One end of the heat-conducting insulating layer 5 contacts the inner wall of the shell body 21 .

[0048] Specifically, the base 22 is in direct physical contact with the liquid cooling plate 1 , and the physical contact area between the two is increased as much as possible to achieve a good heat conduction effect, for example, the base 22 completely covers the liquid cooling plate 1 .

[0049] The connection between the shell body 21 and the base 22 is preferably an integrally formed connection to ensure good integrity of the heat-conducting shell 2 .

[0050] Further, such as Figure 1 and 3 The heat-conducting housing 2 includes a plurality of connecting pieces 23 spaced apart from each other, and the plurality of connecting pieces 23 are connected between the housing body 21 and the base 22. The connecting pieces 23 are configured in the shape of fins, the fins are arranged vertically, and further have a heat dissipation hole 24 running through the entire fin array, and the heat dissipation hole 24 is convenient for further achieving a good heat dissipation effect and for reducing weight.

[0051] Specifically, the plurality of connecting pieces 23 are used to increase the heat transfer area between the shell body 21 and the base 22 , thereby facilitating an increase in the heat transfer rate, and further improving the heat dissipation performance of the inductor body 3 .

[0052] Further, such as Figure 3 The top of the shell body 21 is used to connect with the inductor body 3 , and one end of the thermally conductive insulating layer 5 is in contact with the inner wall of the side of the shell body 21 .

[0053] Specifically, the top of the shell body 21 is used to connect with the inductor body 3, so as to fix the inductor body 3 inside the shell body 21; one end of the thermally conductive insulating layer 5 is in contact with the side inner wall of the shell body 21, which is equivalent to having a gap between the side inner wall of the shell body 21 and the inductor body 3, and the thermally conductive insulating layer 5 is filled in the gap, and the width of the gap ranges from 1 to 2 mm.

[0054] Further, such as Figure 1 , the spacings between the plurality of connecting pieces 23 are equal.

[0055] Specifically, the equal spacing facilitates good distribution uniformity of heat transfer of the plurality of connecting pieces 23 .

[0056] Further, such as Figure 1 The liquid cooling plate 1 and the base 22 are detachably connected via fasteners.

[0057] Specifically, the detachable connection facilitates timely replacement or maintenance of the heat-conducting housing 2, and the fasteners may be screws, bolts, and the like.

[0058] Further, such as Figure 4 , the liquid cooling plate 1 comprises:

[0059] A plate body 11, wherein a cooling channel 12 is provided in the plate body 11;

[0060] A liquid inlet nozzle 13 and a liquid outlet nozzle 14 both communicated with the cooling channel 12;

[0061] The heat-conducting housing 2 and the plate body 11 are connected.

[0062] Specifically, the plate body 11 is used to carry the heat-conducting housing 2 ; the cooling channel 12 is used to allow the coolant to pass through, and to circulate the coolant through the liquid inlet nozzle 13 and the liquid outlet nozzle 14 .

[0063] The plate body 11 is a rectangular ring-shaped body. The plate body 11 is ring-shaped in appearance and has a rectangular cross section, so that the cross section of the cooling channel 12 provided in the plate body 11 is also substantially rectangular.

[0064] The plate body 11 can be bent along the width direction of the entire tube body through a bending forming process, so that the entire tube body is bent into a rectangular ring body, so that the liquid inlet nozzle 13 and the liquid outlet nozzle 14 are connected end to end. It should be noted that the liquid inlet nozzle 13 and the liquid outlet nozzle 14 are not directly connected, and there is a metal spacer between the liquid inlet nozzle 13 and the liquid outlet nozzle 14.

[0065] The plate body 11 is a rectangular annular body. Except for the liquid inlet nozzle 13 and the liquid outlet nozzle 14 located at the fourth corner portion 114, the first corner portion 111, the second corner portion 112, and the third corner portion 113 are all arc-shaped, which is an inevitable result of the bending forming process of the pipe body. At the same time, the arc-shaped first corner portion 111, the second corner portion 112, and the third corner portion 113 can make the flow of the coolant in the cooling channel 12 smoother.

[0066] Further, such as Figure 4 The liquid cooling plate 1 further includes a concave-convex portion 15 disposed in the plate body 11 , and the concave-convex portion 15 is located in the cooling channel 12 .

[0067] Specifically, the concave-convex portion 15 is used to increase the contact area between the coolant and the cooling channel 12 , thereby increasing the heat exchange area, further improving the heat dissipation performance of the inductor body 3 .

[0068] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
