MAIN ENGINE OUTER CASING STRUCTURE OF AIR COOLED HEAT PUMP UNIT

摘要

Disclosed is a main engine outer casing structure of an air cooled heat pump unit, which belongs to the technical field of heat pumps. The main engine outer casing structure comprises a finned heat exchanger containing chamber (14) and a main engine containing chamber (15). A finned heat exchanger (7) is fixed in the finned heat exchanger containing chamber (14). The periphery of the finned heat exchanger containing chamber (14) is provided with a main air deflector (3) fixed on the air inlet side of the finned heat exchanger (7) and side air blocking mechanisms fixed at two ends of the finned heat exchanger (7). The lower part of the main air deflector (3) is provided with an air deflecting mechanism. An air vent is further arranged below the finned heat exchanger containing chamber (14). Exterior air passes through the air vent and the air deflecting mechanism, and then flows upwards and reaches the finned heat exchanger (7). By the air deflecting mechanism, the air input amount of the finned heat exchanger (7) can be guaranteed and at the same time, the air deflecting mechanism deflects air, reducing frosting of the finned heat exchanger (7), and improving the defrosting speed.
