[0002] Heat exchanger is a device that transfers part of the heat of hot fluid to cold fluid. It is also called heat exchanger. Heat exchanger plays an important role in chemical, petroleum, power, food and many other industrial production. In chemical production, heat exchanger can be used as heater, cooler, condenser, evaporator and reboiler, etc., and is widely used.

[0003] However, in actual applications, when most existing air exchangers cool the external air, the moisture in the air will condense into frost due to the low temperature and form adhesion, which will lead to a decrease in the heat exchange efficiency over time, making its use very limited and not conducive to its promotion and use.

[0004] Therefore, those skilled in the art provide a cold and hot air exchanger to solve the problems raised in the above background technology. Utility Model Content

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. By setting a brush plate, the output shaft of the motor cooperates with the sprocket and the chain to drive the heat exchange tube to rotate, which can improve the heat exchange efficiency. At the same time, when the heat exchange tube rotates, it drives the mounting plate to rotate, and the mounting plate drives the reciprocating screw to rotate, and the reciprocating screw drives the gear to rotate. When the gear rotates, it is limited by the gear ring to form self-rotation, and the self-rotation of the gear drives the reciprocating screw to rotate, and the reciprocating screw drives the brush plate to move back and forth left and right, so that the surface of the heat exchange tube can be cleaned to avoid frost coverage, thereby ensuring the heat exchange efficiency while reducing the limitations of use.

At the same time, when the heat exchange tube 2 rotates, it drives the mounting plate 3 to rotate, and the mounting plate 3 drives the reciprocating screw rod 4 to rotate, and the reciprocating screw rod 4 drives the gear 7 to rotate. When the gear 7 rotates, it is limited by the gear ring 6 to form self-rotation. The self-rotation of the gear 7 drives the reciprocating screw rod 4 to rotate, and the reciprocating screw rod 4 drives the brush plate 5 to move back and forth left and right, so that the surface of the heat exchange tube 2 can be cleaned to avoid frost coverage, thereby ensuring the heat exchange efficiency while reducing the limitations of use.
