Description

Technical Field

[0001] This utility model belongs to the field of evaporator duct technology, and specifically relates to an evaporator duct assembly. Background Technology

[0002] An evaporator is a heat exchange device, along with a compressor, condenser, and expansion valve, collectively known as the four major components of refrigeration. Its working principle is that when liquid refrigerant vaporizes within it, it absorbs heat from the object being cooled, thus lowering the object's temperature and achieving refrigeration. The evaporator duct transports the cold air generated by the evaporator to the space requiring cooling. Because the evaporator duct's endpoint is the space requiring refrigeration, after prolonged use, dust accumulated inside the duct will be introduced into the refrigerated space along with the cold air, resulting in poor air quality. Furthermore, the internal space of the duct cannot be easily cleaned manually, leading to long cleaning intervals.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content
