Alternatively, the heat dissipation substrate 1 may also be a vapor chamber or the like.

In practice, the heat dissipation substrate 1 of the heat sink may be a part of the casing of the communication device, and correspondingly, the first surface of the heat dissipation substrate 1 is the outer surface of the casing. The shape of the heat dissipation substrate 1 may be cylindrical or square, and its shape and size mainly depend on the structure of the communication device. A plurality of heating components are installed inside the communication equipment, for example, a main board, a circuit board, a chip, etc., in order to accelerate the heat dissipation of these heating components, correspondingly, these heating components can be in contact with the second surface of the heat dissipation substrate 1 . For example, the heating components can be installed on the second surface of the heat dissipation substrate 1, or the heating components can be directly attached to the second surface of the heat dissipation substrate 1, or the heating components can be installed on the second surface of the heat dissipation substrate 1, or the heating components can be installed on the second surface of the heat dissipation substrate 1.

It can be seen that the oblique heat dissipation teeth array 2 includes a plurality of oblique heat dissipation teeth 22 and a plurality of ventilation slots twenty one. As shown in FIG. 1 , since the ventilation groove 21 is formed by two adjacent parallel oblique cooling teeth, the ventilation direction of the ventilation groove 21 is parallel to the oblique cooling teeth 22 .

For example, if the structure of the communication equipment is large, the internal heating components more, the heat generated is more, correspondingly, the width of the vertical ventilation channel 3 will be larger. The included angle between the ventilation groove 21 of each oblique cooling tooth array 2 and the vertical ventilation channel 3 is a preset angle, and the preset angle can be greater than zero degrees and less than ninety degrees, for example, can be It is 45 degrees, and the preset angle is related to the heat dissipation effect of the radiator, and technicians can determine it based on theoretical calculation and trial and error.

Both ends of the array 2 along the vertical air duct 3 are respectively provided with vertical cooling tooth arrays 4 , and in terms of positional relationship, at least two oblique cooling tooth arrays 2 are located between the two vertical cooling tooth arrays 4 . As shown in Figure 2, the ventilation groove 41 of the vertical cooling tooth array 4 is parallel to the vertical ventilation channel 3, because the included angle between the ventilation groove 21 of each oblique cooling tooth array 2 and the vertical ventilation channel 3 is The preset angle, so there is also an included angle of a preset angle between the vertical cooling teeth 42 and the oblique cooling teeth 22 .

Wherein, as shown in Figure 2, the vertical heat dissipation tooth array 4 is a heat dissipation tooth array composed of a plurality of vertical heat dissipation teeth 42, and there is also ventilation between two adjacent vertical heat dissipation teeth 42 in the vertical heat dissipation tooth array 4. The slot 41 , that is, the vertical cooling tooth array 4 also includes the vertical cooling tooth 42 and the ventilation slot 41 .

It can be seen that the heat sink with the above structure can improve its heat dissipation effect and accelerate heat dissipation for communication equipment.

Optionally, in order to accelerate the cooling air to bring heat to the environment, correspondingly, the ventilation directions of the ventilation grooves 21 of two adjacent oblique cooling tooth arrays 2 are different.

Optionally, in order to increase the number of ventilation slots to improve the heat dissipation effect of the radiator, correspondingly, diversion branches can be arranged on the sheet-shaped heat dissipation teeth, columnar heat dissipation teeth or tubular heat dissipation teeth. Branches are set at the end, on the one hand, it can increase the heat dissipation area, on the other hand, a ventilation groove is also formed between the main trunk of the heat dissipation teeth and the branches, which can divert the flowing air. In addition, it is also possible to bend the end parts of the sheet-shaped heat dissipation teeth, columnar heat dissipation teeth or tubular heat dissipation teeth to one side. Obviously, the length of the bend is longer, which in turn can increase the heat dissipation area of the heat dissipation teeth. Wherein, the heat dissipation teeth include the above-mentioned oblique heat dissipation teeth and vertical heat dissipation teeth.

Optionally, the above-mentioned oblique cooling teeth 22 and vertical cooling teeth 42 can be made of materials with relatively high thermal conductivity, for example, they can be made of metal materials, and the metal materials can be metal aluminum or metal copper or aluminum alloy or copper Alloys, etc.; for another example, it can also be made of non-metallic materials, and the non-metallic material can be graphite; for another example, it can also be heat pipes and so on.
