[0002] Heat pump technology is a technology that uses a small amount of high-quality energy to drive the compressor to upgrade low-quality heat energy to high-quality heat energy to meet user needs. Among them, the heat pump unit is a common heat pump equipment, and its core part is the fin heat exchanger. Through the heat exchanger, heat is exchanged with the external environment to achieve efficient operation of the heat pump system. However, due to the high height of the fin heat exchanger, there is a difference in the air flow between the upper and lower parts, which will affect the heat exchange effect of the heat exchanger and may even cause uneven frosting.

[0003] In order to solve this problem, the existing technical solution is usually to set a conical air guide cover in the middle of the fin heat exchanger. The design concept of the air guide cover is to change the air flow so that the air flow in the upper and lower parts of the entire heat exchanger is close to uniform, thereby improving the heat exchange efficiency and avoiding uneven frosting.
