[0034] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0035] In order to solve the above technical problems, the present application embodiment provides a radiator housing 100, such as Figures 1 to 3 As shown, the radiator housing 100 includes a heat sink 1, a cover 2, an end plate 3 and a fixing member 4. The cover 2 is removably covered on one side of the heat sink 1, and the end plate 3 is arranged on the side of the heat sink 1 facing the cover 2. A receiving cavity is formed between the cover 2, the end plate 3 and the heat sink 1, and the receiving cavity is used to install the electronic component 200. The electronic component 200 may include a power control chip, an automobile power control chip, etc. The fixing member 4 is arranged on the cover 2, and the fixing member 4 is used to fix the cover 2 to an external facility, such as a vehicle body, a power cabinet, etc. In the present application, since the receiving cavity is formed between the cover 2 and the heat sink 1, there is no need to assemble the shell first, and it is only necessary to assemble the cover 2 and the heat sink 1 together, which can not only simplify the structure of the radiator housing 100, but also simplify the assembly steps and improve the assembly efficiency.

[0036] For the above heat sink 1, Figure 2 and Figure 3As shown, the heat sink 1 may be in the shape of a rectangular plate, and the heat sink 1 includes a first mounting surface 11 and a second mounting surface 12 which are arranged opposite to each other along a first direction X, the first mounting surface 11 is provided with a first limiting rib 111, and the second mounting surface 12 is provided with a second limiting rib 121, and the first limiting rib 111 and the second limiting rib 121 both extend along a second direction Y. The first direction X and the second direction Y are perpendicular to each other, and the first direction X and the second direction Y are both parallel to the plate surface of the heat sink 1; the third direction Z is perpendicular to the plate surface of the heat sink 1, that is, parallel to the thickness direction of the heat sink 1. In some other embodiments, the heat sink 1 may also be in the shape of a circular plate, a triangular plate, or a pentagonal plate.

[0037] like Figure 2 and Figure 3 As shown, the first mounting surface 11 and the second mounting surface 12 are both end surfaces of the heat sink 1, the first mounting surface 11 and the second mounting surface 12 are parallel to each other, and the first mounting surface 11 and the second mounting surface 12 are used to connect with the cover 2. Since the first mounting surface 11 and the second mounting surface 12 are both end surfaces of the heat sink 1, when the cover 2 is fixed to the heat sink 1, it is not necessary to turn over the radiator housing 100, which simplifies the assembly steps and improves the assembly efficiency.

[0038] When assembling the radiator housing 100, the first limiting rib 111 and the second limiting rib 121 are used for the cover 2 to abut against each other to position the cover 2 relative to the heat sink 1 along the third direction Z, thereby facilitating the alignment of the cover 2 and the heat sink 1 to improve assembly efficiency. Alignment refers to adjusting the relative position of the two to a preset position during assembly.

[0039] Furthermore, if Figure 2 and Figure 3 As shown, the heat sink 1 further includes a third mounting surface 13, which is located on one side of the heat sink 1 along the second direction Y. The third mounting surface 13 is an end surface of the heat sink 1, and the third mounting surface 13 is connected to the first mounting surface 11 and the second mounting surface 12, and the third mounting surface 13 is perpendicular to the first mounting surface 11 and the second mounting surface 12, and the third mounting surface 13 is used to connect to the housing 2.

[0040] When assembling the radiator housing 100 , the cover 2 can abut against the third mounting surface 13 to position the cover 2 relative to the heat sink 1 along the second direction Y, further facilitating alignment between the cover 2 and the heat sink 1 and improving assembly efficiency.

[0041] like Figure 2 and Figure 3 As shown, a heat sink 14 is disposed on the side of the heat sink 1 away from the accommodating cavity. The heat sink 14 may be a heat sink fin to enhance the heat dissipation effect of the heat sink 1 .

[0042] The heat sink 1 can be made of metal to improve the heat conduction effect and thus improve the heat dissipation efficiency.

[0043] For the above-mentioned housing 2, if Figure 2 and Figure 3 As shown, the housing 2 includes a top wall 21, a first side wall 22, a second side wall 23 and a third side wall 24. The top wall 21, the first side wall 22, the second side wall 23 and the third side wall 24 can be in the shape of a rectangular sheet, the first side wall 22, the second side wall 23 and the third side wall 24 are respectively connected to the three sides of the top wall 21, and the first side wall 22, the second side wall 23 and the third side wall 24 are perpendicular to the top wall 21, so the housing 2 is roughly rectangular. Among them, the first side wall 22 and the second side wall 23 are arranged at intervals along the first direction X, and the third side wall 24 is located between the first side wall 22 and the second side wall 23. In some other embodiments, the housing 2 can also be in other shapes, such as cylindrical, prismatic, etc., as long as it can be covered on the heat sink 1.

[0044] The housing 2 is detachably connected to the first mounting surface 11, the second mounting surface 12, and the third mounting surface 13 through the first side wall 22, the second side wall 23, and the third side wall 24, respectively, so as to connect the housing 2 to the heat sink 1. Optionally, the first mounting surface 11, the second mounting surface 12, and the third mounting surface 13 are detachably connected to the housing 2 through fasteners, such as detachably connected through screws or bolts, that is, the housing 2 is detachably connected to the heat sink 1 through fasteners.

[0045] Furthermore, if Figure 2 and Figure 3 As shown, the first side wall 22, the third side wall 24 and the second side wall 23 are connected in sequence to enhance the overall strength of the housing 2 and enhance the sealing performance of the housing 2 to the accommodating cavity.

[0046] When assembling the radiator shell 100, the first side wall 22 abuts against the first limiting rib 111, and the second side wall 23 abuts against the second limiting rib 121 to position the cover shell 2 relative to the heat sink 1 along the third direction Z; the third side wall 24 abuts against the third mounting surface 13 to position the cover shell 2 relative to the heat sink 1 along the second direction Y, which facilitates the alignment of the cover shell 2 and the heat sink 1 and improves assembly efficiency.

[0047] The cover 2 may be made of metal to improve the heat conduction effect and thus improve the heat dissipation efficiency.

[0048] For the above end plate 3, if Figure 2 and Figure 3As shown, the end plate 3 is disposed at one end of the heat sink 1 in the opposite direction of the second direction Y; when the cover 2 is disposed on one side of the heat sink 1, the end plate 3 is located between the first side wall 22 and the second side wall 23, and the end plate 3, the heat sink 1 and the cover 2 jointly define a receiving cavity. In other embodiments, the end plate 3, the first side wall 22, the second side wall 23 and the third side wall 24 are respectively disposed on the four sides of the top wall 21, that is, the end plate 3 is a part of the cover 2.

[0049] like Figures 1 to 3 As shown, when the housing 2 is mounted on the heat sink 1, the top wall 21 is parallel to the heat sink 1, the first side wall 22, the second side wall 23 and the third side wall 24 are all perpendicular to the heat sink 1, and the end plate 3 is parallel to the third side wall 24, then the accommodating cavity is in a rectangular parallelepiped shape. It can be understood that when viewed along the second direction Y, the housing 2 and the third side wall 24 have the same shape and size.

[0050] like Figure 2 As shown, an electrical connector 31 is provided on the side of the end plate 3 facing away from the accommodating cavity, and the electrical connector 31 is used to electrically connect to the electronic component 200 in the accommodating cavity, thereby facilitating electrical connection between the electronic component 200 in the accommodating cavity and external facilities.

[0051] The end plate 3 can be fixed to the heat sink 1 by welding or bonding, or can be detachably connected to the heat sink 1 by fasteners, such as by screws or bolts. Further, the end plate 3 is detachably connected to the housing 2 by fasteners, such as by screws or bolts, to enhance the stability of the connection between the housing 2 and the heat sink 1.

[0052] For the above-mentioned fixing member 4, Figure 2 and Figure 3 As shown, the fixing member 4 is disposed on the housing 2, and the fixing member 4 is provided with a fixing hole 41. The fixing hole 41 is used to connect with external facilities to fix the radiator housing 100 to the external facilities. There are two fixing members 4, and the two fixing members 4 are respectively disposed on opposite sides of the housing 2 along the first direction X. In the embodiment of the present application, the two fixing members 4 are respectively disposed on the first side wall 22 and the second side wall 23. Optionally, the fixing member 4 is detachably connected to the housing 2 by a fastener, such as a detachably connected by a screw or a bolt.

[0053] like Figure 2 and Figure 3 As shown, the fixing member 4 may be in the shape of an angle steel, that is, the fixing member 4 includes a first wall 42 and a second wall 43 perpendicular to each other, the first wall 42 is connected to the housing 2, and the second wall 43 is provided with a fixing hole 41. The fixing hole 41 may be a gourd hole, so that the radiator housing 100 can be quickly installed or removed from an external facility.

[0054] The fixing member 4 may be made of metal and can transfer the heat of the housing 2 to external facilities.

[0055] In the radiator housing 100 of the embodiment of the present application, a receiving cavity is formed between the cover shell 2 and the heat sink 1, so there is no need to assemble the shell first, and the cover shell 2 and the heat sink 1 only need to be assembled together, which can simplify the structure of the radiator housing 100 and simplify the assembly steps. The cover shell 2 is connected to the first mounting surface 11 and the second mounting surface 12, that is, the cover shell 2 is connected to the side wall of the heat sink 1, and there is no need to flip the radiator housing 100 during assembly, and the heat sink 1 is provided with a limiting rib, which can assist in aligning the position between the cover shell 2 and the heat sink 1, thereby simplifying the assembly steps and improving the assembly efficiency. The third side wall 24 of the cover shell 2 can abut against the third mounting surface 13 of the heat sink 1 to position the cover shell 2 relative to the heat sink 1 along the third direction Z, further improving the assembly efficiency.
