Description

Evaporator assembly and refrigeration equipment Technical Field The utility model relates to the technical field of refrigeration, in particular to an evaporator assembly and refrigeration equipment. Background The refrigeration principle of a refrigeration device mainly depends on the change of state of the refrigerant and the cyclic operation of the compressor. The refrigerant changes from a liquid state to a gas state in the evaporator, and absorbs heat in the refrigeration equipment, thereby reducing the temperature in the refrigeration equipment. The gaseous refrigerant is sucked by the compressor and compressed into a high-temperature and high-pressure gas, and then releases heat through the condenser to gradually condense into a liquid. After the high-pressure liquid is throttled and depressurized by a capillary tube, the high-pressure liquid enters the evaporator again, and continues to vaporize and absorb heat, so that a circulating refrigeration process is formed. In the refrigerating process of the evaporator, the temperature of the evaporator is far lower than that of surrounding air, water vapor in the air is easy to condense at the evaporator, and the evaporator is easy to frost under the condition of long-term working of the refrigerating equipment, so that the normal working of the refrigerating equipment is influenced. Therefore, the evaporator in the current refrigeration equipment is usually additionally provided with a heating assembly to assist defrosting. The air outlet in the refrigeration equipment is usually towards one side of the evaporator, and because the air flow of the air outlet is relatively concentrated, larger frost amount is easy to generate at the relative position of the evaporator and the air outlet, but the emissivity and the heat conduction efficiency of the heating component are low, so that the defrosting time is long and the defrosting effect is poor.
