Description

technical field [0001] The invention belongs to the technical field of heat transfer, and in particular relates to a convection cooling device. Background technique [0002] Fan cooling is a commonly used heat dissipation method at present. The disadvantages are noise, energy consumption, dust and air exchange are adversely affected by the environment. Convection heat dissipation is a fanless heat dissipation mode. At present, the commonly used convection heat dissipation method is to use thick metal parts to increase the contact area between the heat source and the air. This will increase the cost of heat dissipation. At the same time, the heat source and metal parts The distance is also limited by the heat transfer distance and efficiency of the heat pipe. More importantly, this heat dissipation method cannot be applied to high-power heat dissipation, and is limited by the structure of existing electronic products. Therefore, how to successfully apply convection heat diss...

Problems solved by technology

[0003] In heat dissipation technology, almost all the heat is dissipated into the air. Generally, in order to increase the surface area of ​​the part in contact with the air, a structure of multiple heat dissipation fins is often arranged side by side. Although this structure can increase the contact area with the air, However, it cannot be coordinated with the home environment, and it is difficult to directly use it as an appearance. It is often necessary to add a cover to the outside, which will inhibit the flow of air, and the designer has to introduce a fan.

In addition, the manufacturing process of the heat dissipation fins is complicated, the material cost is high, and the shape of the heat dissipation fins is severely limited by the space.

When dust adheres to the surface of the heat dissipation fins, the heat dissipation performance will be reduced, and these dusts are difficult to remove with a rag, and high-pressure airflow is often required, which greatly limits the frequency of dust removal and increases the cleaning cost
