AI Technical Summary

Technical Problem

In existing refrigeration equipment, the amount of frost at the bottom of the evaporator is large, which affects the refrigeration effect and is difficult to solve effectively.

Method used

An evaporator assembly is designed, including first and second evaporators, with a frost-collecting notch at the bottom and equipped with a heating device. The frost-collecting notch area is heated by the heating device to defrost, thereby reducing the contact area between the frost layer and the fins and improving the defrosting efficiency.

Benefits of technology

It effectively reduces the amount of frost at the bottom of the evaporator, improves defrosting efficiency, avoids disorderly accumulation of frost that blocks the air duct, reduces thermal resistance, and achieves rapid defrosting at low temperatures.

Abstract

The utility model discloses an evaporator assembly and refrigeration equipment, evaporator assembly is used for installing in refrigeration equipment, and evaporator assembly includes including first evaporator, second evaporator and heating device, and first evaporator includes first evaporation pipeline and first fin, and second evaporator includes second evaporation pipeline and second fin, and the downside of evaporator assembly has the frost -bearing gap, and heating device is used to heat defrosting for first evaporator and second evaporator. The frost -bearing gap of evaporator assembly downside can play the role of guiding frost layer, and frost layer can directional extension to the gap. Heating device heats evaporator assembly to defrost evaporator assembly surface, and the frost -bearing gap of evaporator assembly bottom cooperates heating device, can make evaporator assembly bottom more efficient realization defrosting.
