Abstract

The invention provides a heat exchanger and an air conditioner. The heat exchanger comprises a heat exchanger body and fins arranged on the heat exchanger body, and the fins located on the lower portion of the heat exchanger body are drag reduction fins. According to the technical scheme, the fins located on the lower portion of the heat exchanger body are arranged to be the drag reduction fins, the heat exchanger can reduce drag of inlet air on the lower portion, the flow speed of the inlet air on the lower portion of the heat exchanger is increased, the air inlet amount is increased, and therefore the uniformity degree of the overall air speed of the heat exchanger is improved, the overall air speed distribution of the heat exchanger is close to the optimal state, and the heat exchange efficiency of the heat exchanger is greatly improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heat exchanger and an air conditioner. Background technique [0002] With the development of refrigeration technology, the energy efficiency of air conditioners has been significantly improved. The ideal wind speed distribution of the heat exchanger is that the wind speeds at the upper and lower parts reach the optimal state, making the heat exchange effect the best. [0003] However, at present, most of the outdoor unit heat exchangers have too high air flow velocity in the upper part and low air flow velocity in the lower part due to the blockage of components, resulting in the wind speed distribution of the heat exchanger being: the upper part is too high and the lower part is too low, resulting in the overall heat exchange efficiency. lower. Contents of the invention [0004] Embodiments of the present invention provide a heat exchanger and an air conditioner to...
