Low wind resistance type thin evaporator and indoor unit of air conditioner

Abstract

The invention provides a low wind resistance type thin evaporator and an indoor unit of an air conditioner and can be used for solving the problems in the prior art that the heat exchange efficiency and the energy-efficiency ratio can not be improved and the cost simultaneously can not be reduced, and the minimization is not beneficial. According to the technical scheme, the evaporator is in a two-folding three-section structure, and is divided into an evaporator A, an evaporator B and an evaporator C; the evaporator A and the evaporator B are respectively in a double-row structure; the evaporator C is in a single-row structure; the evaporator A is connected with the evaporator B; the evaporator C is connected with the evaporator B; and the evaporator C is located at the lower part of the evaporator B. The evaporator provided by the invention adopts a single-row and double-row combined manner, so that that the ultrathin design can be realized; the entire wind resistance of the evaporator can be reduced; the requirement on small space size can be met; and the structure is relatively compact.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration engineering, and in particular relates to a thin evaporator with low wind resistance and high-efficiency heat exchange. Background technique [0002] The space type, wind field distribution, fin type, and tube layout design of the heat exchanger on the air conditioner are very important, which will directly affect the efficiency of convective heat transfer, thereby affecting the level of heat transfer. The space type is closely related to the wind field distribution and depends on the size of the air conditioner. There are various forms of air-conditioning heat exchanger fins, from the initial flat fins and corrugated fins to the later development of louver fins and slotted fins. The arrangement of tube rows is adjusted based on the distribution of the box wind field in order to obtain higher heat exchange efficiency. [0003] In recent years, due to fierce market comp...
