Problems solved by technology
However, for small-diameter heat exchangers, as the dryness in the heat exchange tube increases, the heat transfer coefficient of the heat exchanger will first increase and then decrease, which will affect the heat transfer performance of the heat exchanger.

Embodiment Construction
[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0020] Figure 1 to Figure 3 It is a preferred embodiment of an air conditioner heat exchanger provided by the present invention. Such as Figure 1 to Figure 3 As shown, the air conditioner heat exchanger includes a first heat exchanger group 10, a second heat exchanger group 20 and a third heat exchanger group 30, the three are arranged in a "U" shape, and the second heat exchanger The group 20 is located between the first heat exchanger group 10 and the third heat exchanger group 30, and the first heat exchanger group 10 is close to the side of the wall where the air conditioner is installed. The second heat exchanger group 20 is movably connected with the first heat exchanger group 10 and the third heat exchanger group 30, and the angle α between the second heat exchanger group and the first heat exchanger group is 95°~120°, The angle β between the second heat ...

The invention provides a heat exchanger for an air conditioner. The heat exchanger comprises a first heat exchanger unit, a second heat exchanger unit and a third heat exchanger unit. The two ends of the second heat exchanger unit are movably connected with the first heat exchanger unit and the third heat exchanger unit correspondingly, and the three heat exchanger units are arranged in a U shape. Each heat exchanger unit comprises a heat exchange tube and a fin unit connected to the heat exchange tube in a sleeving mode. The diameter of the inlet end and the diameter of the outlet end of the heat exchange tube of each heat exchanger unit are smaller than the diameter of the middle section of the heat exchange tube, and the diameter of the middle section of the heat exchange tube of the second heat exchanger unit is smaller than the diameter of the middle section of the heat exchange tube of the first heat exchanger unit and the diameter of the middle section of the heat exchange tube of the third heat exchanger unit. Compared with the prior art, the diameters of the heat exchange tubes in the three heat exchanger units are changed, the distance of fins in the windward fin units is larger than the distance of fins in the leeward fin units, and therefore the heat exchange coefficient of the whole heat exchanger is high, and heat exchange performance is good; energy is saved, the environment is protected, adoption of copper and aluminum in the air conditioner is reduced, and the manufacturing cost of the air conditioner is lowered.
Description
technical field [0001] The invention relates to the field of air conditioning, in particular to a heat exchanger for air conditioning. Background technique [0002] Air conditioning is air conditioning, which refers to the process of adjusting and controlling the temperature, humidity, air cleanliness, speed and other parameters of the ambient air in the building / structure by manual means. Air conditioners generally include cold source / heat source equipment, cold and hot medium transmission and distribution system and terminal devices, and other auxiliary equipment, while heat exchangers are an important part of the cold and hot medium transmission and distribution system. Heat exchangers in air conditioners are usually made of copper heat exchange tubes and aluminum fins, so the air conditioner industry consumes a lot of copper and aluminum resources. [0003] In order to improve heat exchange efficiency, very high-purity copper-aluminum is usually used in heat exchangers....
