Technical Field
The present disclosure relates to the field of air conditioners, and more particularly, to a heat exchanger for an indoor unit of an air conditioner and a unit thereof.
Background
The air conditioner is the necessary equipment for adjusting indoor temperature and humidity. The heat exchanger of the wall-mounted air conditioner indoor unit is in a multi-fold round pipe form, and fins are additionally arranged on the round pipe to improve the heat exchange efficiency. The diameter of the round tube is 4-10 mm. The larger pipe diameter enables the heat exchange efficiency of the heat exchanger to be at a lower level, and then the size of the whole heat exchanger is required to be larger, so that the size of the indoor unit of the air conditioner cannot be obviously reduced.
As the demands of residents on the beauty of home decoration are continuously increased and higher demands are also made on the appearance and size design of the indoor unit of the air conditioner, the miniaturized indoor unit will be more popular. Miniaturized indoor units necessarily require more compact, more efficient heat exchangers.
With the development of the micro-scale heat transfer technology, the ultra-compact heat exchanger begins to appear in the fields of electronic component cooling, aerospace heat transfer and the like, has the advantages of high heat exchange efficiency, small structural size and material conservation, but has processing difficulty and processing cost obviously higher than those of the conventional heat exchanger, and provides higher requirements for the flow channel design, the structural design and the process design of the heat exchanger if the ultra-compact heat exchanger is used in the field of air conditioners. Accordingly, the present disclosure has been made.
