Description

Technical Field

[0001] The utility model belongs to the technical field of electric heaters, and in particular relates to a large auxiliary air duct electric heater. Background Art

[0002] Duct-type auxiliary electric heaters mainly use tubular electric heating element assemblies (devices) with wound heat dissipation fins or other electric heating element assemblies (devices) with high efficiency and energy saving effects, such as exposed heating wire structures or ceramic PTC aluminum heat sink type electric heating element assemblies. Electric heating tubes with wound heat dissipation fins are made by spirally winding stainless steel heat dissipation belts (commonly known as "fins") on the electric heating tubes using a special process with technical know-how. This greatly improves the heat dissipation efficiency of tubular electric heating elements under wind speed conditions. Exposed heating wire electric heating elements eliminate unnecessary heat conduction links, and the heating wire directly dissipates heat in the flowing air medium, reducing heat conduction heat loss. It is a high efficiency and energy saving heating element. Due to its structural characteristics and excellent performance, this type of product has been recognized and adopted by more and more customers and has become a new growth-oriented product. At present, electric heaters mainly have the following common defects:

[0003] During the use of traditional duct air electric heaters, due to the large internal space of the duct, traditional electric heaters cannot adjust the direction of the heated air according to the required heating position and heating conditions, thereby reducing the uniformity of the auxiliary heating inside the entire duct during use.
