Abstract

The invention discloses a novel heat exchanger, an indoor unit of an air conditioner, and the air conditioner. The novel heat exchanger comprises a plurality of fins and a plurality of refrigerant tubes which penetrate through the fins, wherein the refrigerant tubes are arranged in a spaced mode in the length direction of each fin, and are arranged in single row in an air guide direction; the tubediameters of the refrigerant tubes are 6.8mm-7.5mm, spacing between every two adjacent refrigerant tubes is 15.7mm-24.4mm, and width of the fins is 18mm-27.4mm. According to the technical scheme adopted by the invention, integral energy efficiency of the heat exchanger is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a novel heat exchanger, an air conditioner indoor unit and an air conditioner. Background technique [0002] At present, double-row heat exchangers are generally used in air-conditioning indoor units to increase the heat exchange area of ​​the refrigerant and enhance the heat exchange capacity of the heat exchanger; however, during the application of the double-row heat exchanger, the airflow passes through the heat exchanger, After sufficient heat exchange with the front row fins, the speed of the airflow decreases. At this time, the heat exchange is performed with the rear row fins, and the heat exchange effect is poor, that is, the capacity of the rear row heat exchangers cannot be fully utilized. Actual relevant test data shows that for a double-row heat exchanger, the front row can contribute 70% of the heat exchange, while the rear row can only contribute 30% of th...
