Evaporator and application method of evaporator

Abstract

The invention provides an evaporator and an application method of the evaporator. The evaporator comprises an evaporating pipe, a fin group and a driving mechanism. The evaporating pipe comprises a plurality of parallely arranged straight pipes; the fin group comprises a first fin group and a second fin group; the first fin group comprises a plurality of parallely arranged first fins and the second fin group comprises a plurality of parallely arranged second fins, and the first and second fins are arranged in a spaced manner; the driving mechanism drives the first fin group or the second fin group to move along the straight pipes, so that the separation distances between the first fins and the adjacent second fins are adjusted conveniently. Compared with the prior art, the separation distances among the fins of the evaporator can be adjusted, so that the separation distances among the fins can be adjusted according to different working conditions, the frosting or freezing speed of theevaporator is reduced further, the wind resistance of recirculating air passing the fins is reduced, and therefore, the heat exchange efficiency of the evaporator is improved.

Description

technical field [0001] The invention relates to an evaporator and a method for using the evaporator. Background technique [0002] In the air duct circulation system of the air-cooled refrigerator, the circulating air circulates from the bottom of the evaporator from bottom to top and exchanges heat with the evaporator. When the high-temperature and high-humidity air passes through the evaporator, the water vapor in the high-temperature and high-humidity air will condense on the surface of the evaporator to form a frost layer or an ice layer. Since the circulating wind passes through the evaporator from bottom to top, the distribution of the frost layer or ice layer on the evaporator is also from bottom to top, and the thickness of the frost layer or ice layer gradually decreases from bottom to top. The existing evaporator with fixed fin spacing near the air outlet has a relatively fast rate of frost or ice formation, and the thickness of the frost layer or ice layer is rel...

AI Technical Summary

Problems solved by technology

The existing evaporator with fixed fin spacing near the air outlet has relatively fast frost or ice formation, and the thickness of the frost layer or ice layer is relatively large, which increases the wind resistance when the circulating air passes through the fins, which in turn affects the performance of the evaporator.
