Problems solved by technology

[0003] For clothes dryers with micro-channel evaporators, due to the high fin density of the micro-channel evaporators, the heat exchange efficiency of the micro-channel evaporators is high, but during the use of the clothes dryer, the dust on the clothes Substances such as lint and lint will accumulate on the micro-channel evaporator with the flow of air, making it very difficult to clean and manufacture the micro-channel evaporator. In addition, condensed water will be generated on the surface of the micro-channel evaporator, and water, dust, lint, etc. will easily Solidification on the surface of the fins of the micro-channel evaporator increases the heat transfer resistance between the fins and the air, reduces the heat transfer coefficient of the micro-channel evaporator, and also increases the wind resistance of the air duct of the clothes dryer, reducing the circulation The air volume is not conducive to the improvement of the working efficiency of the dryer
