Problems solved by technology

The heat exchange tube of this heat exchanger has a large diameter and thick fins, resulting in a large amount of copper and aluminum and high cost.
In order to solve the above problems, some heat exchangers use heat exchange tubes with a diameter of 5 mm. The cooling capacity of such small-diameter heat exchangers can reach that of large-diameter heat exchangers, but the heating capacity is reduced.

Abstract

The invention discloses a heat exchanger and a wall-mounted air conditioner with the same. The heat exchanger comprises a first heat exchanger set, a second heat exchanger set and a third exchanger set. The first heat exchanger set is provided with a heat exhaust and exchange pipe, and the second heat exchanger set and the third heat exchanger set are provided with outer heat exhaust and exchange pipes and inner heat exhaust and exchange pipes; a first pipeline comprises at least one outer heat exhaust and exchange pipe of the second heat exchanger set and at least one outer heat exhaust and exchange pipe of the third heat exchanger set, a second pipeline comprises at least one heat exhaust and exchange pipe of the first heat exchanger set and at least one outer heat exhaust and exchange pipe of the second heat exchanger set, and a third pipeline comprises at least one heat exhaust and exchange pipe of the first heat exchanger set and at least one outer heat exhaust and exchange pipe of the second heat exchanger set. The pipeline of the heat exchanger is optimized in design according to air quantity distribution and temperature gradient changes of windward side and leeward side, so that heat transfer coefficient of the refrigerating fluid in the air-conditioner and the heat exchange pipe when the air conditioner starts heating is increased, and heating capacity of the air conditioner in operation is increased.

Description

technical field [0001] The invention relates to an air conditioning system, in particular to a heat exchanger of the air conditioning system and a wall-mounted air conditioner using the heat exchanger. Background technique [0002] The heat exchanger of the indoor unit of the existing wall-mounted air conditioner is as figure 1 As shown, the heat exchanger 10 includes a first folded heat exchanger group 101, a second folded heat exchanger group 102 and a third folded heat exchanger group 103 spliced ​​in sequence, and each folded heat exchanger group includes fins and interspersed There are two rows of U-shaped heat exchange tubes in the fins, and the diameter of the heat exchange tubes is 7mm. The heat exchange tubes of this type of heat exchanger have large tube diameters and thick fins, resulting in a large amount of copper and aluminum and high cost. In order to solve the above problems, some heat exchangers use heat exchange tubes with a diameter of 5 mm. The cooling ...
