Abstract

The application provides an evaporator and an air conditioning unit. According to the evaporator, a first heat exchange tube set and a second heat exchange tube set are arranged in a casing; the second heat exchange tube set is located below a liquid distributor; a first liquid uniformizing tube set is arranged in the casing and is located between the first heat exchange tube set and the second heat exchange tube set; the tube diameter of heat exchange tubes of the first liquid uniformizing tube set is smaller than that of heat exchange tubes of the first heat exchange tube set; and the distribution density of the heat exchange tubes of the first liquid uniformizing tube set is larger than that of the heat exchange tubes of the first heat exchange tube set. By applying the technical scheme, after a refrigerant flows through the first heat exchange tube set, the refrigerant will fall on the first liquid uniformizing tube set. When the refrigerant flows through the first liquid uniformizing tube set, the refrigerant is randomly distributed uniformly through the heat exchange tubes of the first liquid uniformizing tube set, thus, the refrigerant can be re-uniformized again, and the refrigerant can uniformly fall on the second heat exchange tube set. In this way, heat exchange uniformity is of the evaporator is improved, and the overall heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an evaporator and an air conditioner unit. Background technique [0002] In air conditioning and refrigeration systems, pressure vessels are the main components, such as evaporators, condensers, oil separators, flashers, etc. With the continuous development of the technical level, products with higher heat exchange capacity have more advantages and are more competitive when the price and cost are not much different. Through the research on the heat exchange capacity, it is found that the evaporator has undergone great changes in technology. At present, there are dry evaporators, flooded evaporators, and falling film evaporators for shell and tube heat exchangers. From the perspective of prospects, The development of falling film evaporator is considerable, and the development in the industry is also very rapid. [0003] However, there are still many technical bo...
