Heat dissipation assembly and water heater

Abstract

The heat dissipation assembly is used for heat dissipation of an electric control board of the water heater and comprises an installation part and a pushing part, the electric control board is installed in the installation part, and in the thickness direction of the water heater, the electric control board corresponds to the position where an air inlet of a draught fan is located; under the temperature influence of the electric control board, the pushing part applies acting force to the electric control board in the direction close to the draught fan and / or applies acting force to the electric control board in the direction away from the draught fan. According to the scheme, the electric control board is installed through the installation part and is opposite to the air inlet of the fan, and heat of the electric control board can be taken away through air convection. Moreover, acting force can be applied to the electric control board through the pushing part, so that the electric control board moves relative to the fan and the distance between the electric control board and the fan is changed, and therefore, when the electric control board is close to the fan, the electric control board can fully convect and exchange heat, and the cooling effect is improved; when the electric control board is far away from the fan, condensate water can be prevented from dripping into the electric control board to cause short circuit of the electric control board.
