3. The utility model has short start-up time, convenient control, can directly heat the air, rapidly heats up the room, and has good load adaptability.

4. The cooling element is composed of upper and lower sets of copper-aluminum composite rectangular double-tube finned tubes. The upper and lower cooling copper tubes are respectively welded with the front and rear connecting tubes to form a circulating water flow channel. The manufacturing process is simple and easy to produce.

5. The width of the rectangular aluminum fins is equal to the thickness of the steel cover, and they are arranged in the cover to eliminate the gap between the fins and the cover. All the cold air blown by the cross-flow fan flows through the cooling element to enhance heat exchange.

6. The steel outer cover is a complete and tight rectangular air guide cover, with air outlets and air inlets on the upper and lower parts of the front cover, and the flanging and deep drawing process is used to not only look beautiful, but also improve the permeability.
