Heat dissipation device for control heat dissipation assembly and washing machin

Abstract

The invention provides a heat dissipation device, which controls a heat dissipation assembly and a washing machine. The heat dissipation device comprises a water-cooled heat sink (1) capable of receiving condensed water generated by an air-conditioning evaporator, and cooling and dissipating heat through the flow of the condensed water and an electric box (2). The invention effectively replaces the existing heat dissipation mode of using a heat dissipation fan to dissipate heat to the controller, the cooling efficiency of heat dissipation is high, As that radiator has the defect that the temperature of the radiator is high when the radiator is in high frequency operation and the heat dissipation effect is poor, the heat dissipation effect of the radiator is effectively overcome, effectively reducing the temperature of the radiator on the control board when the compressor is running at high frequency, The IPM module of the compressor and the motor is protected from burning out or high temperature protection due to excessive temperature, and the forced convection heat dissipation fan is not required to be added, the volume and weight of the heat dissipation fan are reduced, the structure of the electric box is simplified, the running noise of the whole machine is reduced, and the reliability of the circuit board is improved.

Description

technical field [0001] The invention belongs to the technical field of cooling, and in particular relates to a heat dissipation device, a heat dissipation control component and a washing machine. Background technique [0002] The controller of the existing washing machine and other electrical appliances is provided with a radiator. The main chip on the controller generates a large amount of heat during operation, and the radiator is close to the surface of the main chip, so that the heat of the chip is transferred to the radiator. The heat exchange generated by the outside world keeps the chip in a reasonable temperature range during operation without causing the chip to burn out due to excessive temperature. However, the existing radiators usually use a cooling fan to dissipate heat from the controller. Using a cooling fan as a radiator for cooling will take up a lot of space, be heavy, and will cause a significant increase in the operating noise of the whole machine, and h...
