[0027] The first heat dissipation teeth 10 are fixed to two opposite first side surfaces 30 of the housing, and the second heat dissipation teeth 20 are fixed to a second side surface 40 of the housing adjacent to the first side surface 30. The second heat dissipation teeth 20 are provided on at least one side of the first heat dissipation teeth 10 along the first direction D1, and the extension direction of the first heat dissipation teeth 10 intersects with the extension direction of the second heat dissipation teeth 20.

[0028] The first direction D1 intersects with the second direction D2.

[0029] For more details, please see Figure 1 The heat dissipation device provided in this embodiment is applied to a multi-channel digital chassis equipped with a radar. Usually, there are many boards and modules inside the chassis, and the heat consumption of the boards and modules is relatively large. They are all heat sources that generate heat, such as Figure 1 As shown, a heat source 1 is provided on a first side surface 30 of the shell, a heat source 2 is provided on another first side surface 30 of the shell, and a heat source 3 is provided on the heat source 2. Since the chassis requires sealing and the volume of the chassis needs to be controlled, the internal space of the chassis is limited, and the heat generated by these heat sources is not easy to dissipate. Therefore, it is necessary to solve the heat dissipation problem within the limited space. The heat dissipation device provided in this embodiment is provided with first heat dissipation teeth 10 arranged along the first direction D1 and second heat dissipation teeth 20 arranged along the second direction D2. The first heat dissipation teeth 10 are fixed to two opposite first side surfaces 30 of the shell, and the second heat dissipation teeth 20 are fixed to the second side surface 40 of the shell adjacent to the first side surface 30. On the one hand, the heat source provided on the first side surface 30 can be directly dissipated by the first heat dissipation teeth 10. On the other hand, the heat source provided on the first side surface 30 can be conducted to the second heat dissipation teeth 20 for indirect heat dissipation, thereby improving the heat dissipation capacity and achieving efficient heat dissipation. In addition, the extension directions of the first heat dissipation teeth 10 and the second heat dissipation teeth 20 intersect, which can achieve balanced heat dissipation.

[0030] The first direction D1 intersects with the second direction D2. Optionally, the first direction D1 is perpendicular to the second direction D2.

[0031] It should be noted that the first heat dissipation teeth 10 and the second heat dissipation teeth 20 are formed by processing and welding aluminum or copper plates.

[0032] It should be noted that Figure 1 The illustrated embodiment only schematically shows the positional relationship between the first heat dissipation teeth 10 and the second heat dissipation teeth 20 and does not represent the actual size. The heat source 1 , the heat source 2 and the heat source 3 are all integrated heat sources.

[0033] In an optional embodiment of the present invention, the extending direction of the first heat dissipating teeth 10 is perpendicular to the extending direction of the second heat dissipating teeth 20 .

[0034] For more details, please see Figure 1In this embodiment, the extension direction of the first heat dissipation teeth 10 is perpendicular to the extension direction of the second heat dissipation teeth 20, which can simplify the manufacturing process and achieve optimal balanced heat dissipation.

[0035] In an optional embodiment of the present invention, see Figure 2 , Figure 2 This is another structural diagram of the heat dissipation device provided by an embodiment of the present utility model.

This increases the heat dissipation area and achieves more efficient heat dissipation. Furthermore, when the second heat dissipation teeth 20 are provided on both sides of the first heat dissipation teeth 10 along the first direction D1, the heat pipe 50 can transfer more heat generated by the heat source located on the first side 30 to the second side 40, where it is dissipated by the second heat dissipation teeth 20, achieving more efficient heat dissipation.
