Efficient anti-chassis icing fin heat exchanger and working method thereof

Abstract

The invention provides an efficient anti-chassis icing fin heat exchanger and a working method thereof. The efficient anti-chassis icing fin heat exchanger comprises a fin, a variable resistance heating belt, an anti-freezing working medium pipe and a cold and hot transfer heat pipe, wherein the inner bottom of the fin traverses the anti-freezing working medium pipe, one side of the bottom of thefin is provided with the variable resistance heating belt, and the other side of the bottom of the fin is provided with the cold and hot transfer heat pipe. According to the efficient anti-chassis icing fin heat exchanger, icing and frosting phenomena of the bottom of the fin are completely eradicated, and furthermore, the heat generating performance and energy efficiency of a unit can be improved. By means of the linkage operation among the four-weight modes, the unit can stably and efficiently continuously produce heat, and the negative influence caused by frequent defrosting of the unit isavoided.

Description

technical field [0001] The invention belongs to the field of heat exchange equipment, and in particular relates to a high-efficiency anti-icing chassis fin heat exchanger and a working method thereof. Background technique [0002] When the outdoor ambient temperature is low and the humidity is high, the outdoor heat exchanger of the air source heat pump may frost or even freeze. If defrosting is not effective, it will affect the continuous and efficient operation of the heat pump unit, and eventually cause an alarm to shut down. Air source heat pumps need regular defrosting at low temperatures to solve the problem of fin frosting, but frequent start-stop defrosting will inevitably have a serious impact on the heating of the system, and each reversing defrosting will cause customer The water temperature drops a little. There will inevitably be a time difference between restarting after defrosting and entering stable operation, and these are unfavorable factors that affect t...

AI Technical Summary

Problems solved by technology

[0003] During the transition of winter or autumn and winter, due to the low ambient temperature and high humidity, there is a risk of frost or icing at the bottom of the fin heat exchanger. If the defrosting is not clean, it will cause frost accumulation at the bottom of the fin and eventually freeze. The performance of the air source heat pump unit will be greatly affected, and there may even be a possibility of shutdown protection. In view of the above problems, the present invention provides a high-efficiency anti-icing chassis fin heat exchanger and its working method
