Aluminum Tube And Aluminum Fin Heat Exchanger in Heat Pump Type Equipment (hot Water / Heating)

Aluminum tube and aluminum fin heat exchanger in heat pump type equipment (hot water / heating)

The “evaporator” (absorbing heat from the air) of heat pump equipment (e.g., air-source heat pump water heaters, heat pump heating machines) is an important application scenario for aluminum tube and aluminum fin heat exchanger, especially suitable for regions with mild climate and non-high humidity and high salt.

Air source heat pump water heater (domestic / commercial): the evaporator on the outside of the room needs to exchange heat with the air, the lightweight characteristics of the aluminum tube and aluminum fin can reduce the transportation and installation costs of the heat pump outside the machine, and the surface of the aluminum is easy to form a dense oxidized film (Al₂O₃), which is able to resist slight rust in a dry or mildly humid environment (you need to avoid the “electrochemical corrosion” caused by long-term high humidity and condensation) ", so high humidity coastal areas may require additional anti-corrosion treatment, such as plastic spraying).

Low-temperature heat pump heating machine (low-end and middle-end models): under mild low-temperature working conditions above - 5℃, the aluminum tube and aluminumfin evaporator can be designed with “fins open window” and “hydrophilic coating” (to reduce frost adherence), to enhance the heat exchange efficiency while controlling the cost, suitable for northern It is suitable for domestic heating or small and medium-sized commercial heating (e.g. stores, office buildings) in non-extremely cold areas.
