Since the air conditioner all-in-one machine is exposed to the external environment, especially in the season requiring refrigeration (or dehumidification), the temperature of the electric component in the unit is often in a high-temperature state due to the high-temperature exposure of the external environment and the operation of the air conditioner refrigeration (or dehumidification), which easily leads to the failure of the components due to the excessively high temperature, causing the air conditioner failure and customer complaints. Therefore, a corresponding heat dissipation structure needs to be designed.

[0003] The existing heat dissipation is composed of a bottom plate and a plurality of heat dissipation fins arranged on the bottom plate, and the electronic module is attached to the bottom plate. During operation, the heat generated by the electronic module is conducted on the bottom plate and diffused to the heat dissipation fins through the bottom plate. The use shows that the deficiencies of the prior art are: 1. The heat is only conducted from the bottom plate to the heat dissipation fins, the conduction mode is single, the heat diffusion effect is poor, the temperature difference between the high-temperature and low-temperature areas is obvious, and the heat distribution of the heat dissipation fins is uneven, resulting in uneven heat dissipation. 2. An all-aluminum heat sink is used, which requires a large heat dissipation area, consumes more materials, and has high cost. 3. Due to the weak heat dissipation effect, the working reliability and service life of the electronic module are affected. CONTENT OF THE UTILITY MODEL
