Description

Technical Field

[0002] Cold storage is a warehouse that uses cooling facilities to create suitable humidity and low temperature conditions. It is also called a cold storage. It is a place for processing and storing products. It can get rid of the influence of climate and extend the storage period of various products to regulate market supply. It is mainly used as a constant temperature storage cooling equipment for food, dairy products, meat, aquatic products, etc. Cold storage is actually a low-temperature cold storage and also a kind of refrigeration equipment. Compared with refrigerators, its refrigeration area is much larger, but they have the same refrigeration principle. Air coolers are divided into industrial refrigeration air coolers and household air coolers. Industrial air coolers are generally used in cold storage and cold chain logistics refrigeration environments.

[0003] For example, a cold air blower for cold storage with publication number CN208653042U includes a shell and a blower and a heat exchange coil installed on the shell. The heat exchange coil is provided with more than two layers from the outside to the inside along the air flow direction, and heat exchange fins are arranged in parallel on each layer of the heat exchange coil. The spacing between the heat exchange fins on the outermost heat exchange coil is greater than the spacing between the heat exchange fins on the inner heat exchange coils. The utility model increases the spacing between the heat exchange fins on the outermost heat exchange coil according to the characteristic that the outer fins of conventional heat exchange coils are more likely to frost. On the one hand, it can effectively prolong the time for the heat exchanger surface to frost and reduce the impact of the fin surface frost on the equipment. On the other hand, it can reduce the impact of the outer fin surface frost on the air flow, thereby achieving the purpose of reducing the energy consumption of the equipment. It has a simple structure, is easy to install and use, and effectively reduces the impact of the frost on the heat exchange coil on the heat exchange efficiency of the equipment.
