Problems solved by technology

[0002] At present, the cylindrical cabinet air conditioners on the market have larger air outlets, and the height of the air outlets in the vertical direction is larger. When the air conditioner is running in the heating mode, the refrigerant in the heating cycle of the indoor heat exchanger flows from bottom to top. Yes, due to the inertia of the refrigerant, most of the refrigerant will concentrate on the upper part of the heat exchanger, resulting in high air temperature at the upper part of the heat exchanger and low air temperature at the lower part of the heat exchanger. The deviation is large, the temperature of the air outlet is uneven, and the uneven hot air blows on the body of the consumer, which reduces the comfort of the consumer and causes consumer complaints

Embodiment Construction

[0020] Such as figure 1 , the heat exchanger proposed in the embodiment of the present invention can be applied in an air conditioner indoor unit, especially in a cylindrical cabinet type air conditioner indoor unit. The heat exchanger includes a heat exchanger main body 10 and a refrigerant inlet pipe assembly. The refrigerant inlet pipe assembly includes a main refrigerant inlet pipe 21 and several refrigerant inlet pipes 22. One end of each refrigerant inlet pipe 22 is connected to the main refrigerant inlet pipe 21. The other end of each refrigerant inlet pipe 22 communicates with the heat exchange pipe in the main body of the heat exchanger 10 . Several refrigerant inlet pipes 22 are arranged along the height direction of the heat exchanger body 10 , and the pipe diameters of the several refrigerant inlet pipes 22 are different. In this embodiment, it is preferable that the diameter of the refrigerant inlet pipe 22 located at the upper part of the heat exchanger body 10 ...

Abstract

The invention discloses a heat exchanger and an indoor unit of the air conditioner. The heat exchanger comprises a heat exchanger main body and a plurality of refrigerant sub inlet tubes, wherein eachrefrigerant sub inlet tube communicates with a heat exchange tube in the heat exchanger main body; the refrigerant sub inlet tubes are arranged in the height direction of the heat exchanger main body; and tube diameters of the refrigerant sub inlet tubes are different. According to the heat exchanger disclosed by the invention, flow of a refrigerant on the upper part of the heat exchanger is reduced, and flow of the refrigerant on the lower part of the heat exchanger is increased, so that uneven refrigerant distribution as a result of too great flow on the upper part of the heat exchanger dueto the inertia effect of the refrigerant can be neutralized, and therefore, refrigerant flow of each runner is more uniform, temperature uniformity of outlet air of the air hole of the air conditioner is improved, and comfort is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, and more specifically relates to a heat exchanger and an air conditioner indoor unit. Background technique [0002] At present, the cylindrical cabinet air conditioners on the market have larger air outlets, and the height of the air outlets in the vertical direction is larger. When the air conditioner is running in the heating mode, the refrigerant in the heating cycle of the indoor heat exchanger flows from bottom to top. Yes, due to the inertia of the refrigerant, most of the refrigerant will concentrate on the upper part of the heat exchanger, resulting in high air temperature at the upper part of the heat exchanger and low air temperature at the lower part of the heat exchanger. The deviation is large, the temperature of the air outlet is uneven, and the uneven hot air blows on the body of the consumer, which reduces the comfort of the consumer and causes consumer complaints.
