Technical Field

[0001] The utility model relates to the field of evaporators, in particular to an evaporator. Background Art

[0002] An evaporator is an object or device that converts liquid substances into gaseous state, especially playing an important role in refrigeration systems. Its working principle is that low-temperature condensed liquid vaporizes and absorbs heat through heat exchange with the outside air, thereby achieving a refrigeration effect.

[0003] After searching, the Chinese patent with announcement number CN213421522U discloses that the utility model discloses an evaporator for refrigeration equipment with excellent dissipation effect, including a base plate, and vertical plates are fixedly connected on both sides of the top of the base plate. The utility model discloses an evaporator for refrigeration equipment with excellent dissipation effect, which removes condensed frost on the evaporation tube through the combined action of a temperature sensor, a microprocessor and a defrosting device.

[0004] However, the announcement number CN213421522U uses a low-temperature baking lamp for defrosting. The long-term operation of the baking lamp will cause the internal temperature of the evaporator to rise. While defrosting, it also reduces the refrigeration effect of the evaporator, greatly reducing the function of the evaporator. Utility Model Content
