Description

Technical Field

[0001] The utility model relates to the technical field related to heat pump hot air blowers, and in particular to a heat interaction device for an air source heat pump hot air blower. Background Art

[0002] Hot air blower is the preferred product for upgrading and replacing modern industrial heat sources. Electromechanical equipment is the best hot air source configuration for automated machinery such as hot air conveying furnaces, drying furnaces, ovens, and packaging machines. Hot air blower is a commonly used drying equipment in industry and can be used for rapid heating and drying of workpieces. Hot air blower consists of three major parts: blower, heater, and control circuit. After the hot air blower is powered on, the blower blows air into the heater. The heat generated by the heating wire after being powered on exchanges heat with the cold air passing through. However, during the heat exchange air circulation process, dust and impurities will be contained in the air. After a long period of operation, a large amount of dust and impurities may adhere to and accumulate on the outside of the heater, thereby reducing the heat exchange efficiency of the heater, thereby affecting the overall heating efficiency of the device.

[0003] To this end, we propose a thermal interaction device of an air source heat pump hot air blower to solve the above problems. Utility Model Content
