Circuit heat dissipation device of cooling fan

Abstract

The utility model discloses a circuit heat dissipation device of a cooling fan, which comprises a plastic top shell, a main control circuit board, a function control circuit board, a rechargeable battery, a front surface cover, a rear water tank cover and a metal heat dissipation plate, the front part of the metal heat dissipation plate is tightly fixed on the surface of the circuit board mounting platform; a main control circuit board and a rechargeable battery are fixed at the top of the metal heat dissipation plate tightly fixed on the circuit board mounting platform section; the middle rear part of the metal heat dissipation plate extends and is inserted into the bottom of the wet curtain water diversion water tank; the circuit board installation platform is provided with the metal heat dissipation plate which extends to the wet curtain water diversion water tank, when the main control circuit board and the rechargeable battery generate heat, heat generated by heating can be directly transmitted to the metal heat dissipation plate and then transmitted to the rear portion of the metal heat dissipation plate to make contact with water, the heat is taken away by the water in the continuous flowing process of the water, and the heat dissipation effect is good. Therefore, cooling and heat dissipation of the metal heat dissipation plate can be realized quickly, and indirect heat dissipation of the main control circuit board and the rechargeable battery can be realized.
