Embodiment Construction

[0024] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] like Figure 1-4 The electric heater shown includes two heaters 1 , and the heaters 1 include a heating core 11 , a heat-conducting aluminum tube 12 and a cooling fin 13 . The heating core 11 includes a first insulating sheet 111, a second insulating sheet 112 wound with a resistance wire 114, and a third insulating sheet 113. The second insulating sheet is between the first insulating sheet and the second insulating sheet. Between the three insulating sheets, the first insulating sheet, the second insulating sheet and the third insulating sheet are arranged in t...

Abstract

The invention relates to an electric heater which comprises at least one heater, the heater comprises a heating core, a heat conduction aluminum pipe and cooling fins. The electric heater is characterized in that the heating core comprises a first insulating sheet, a second insulating sheet wound with a resistance wire and a third insulating sheet; the second insulating sheet is positioned betweenthe first insulating sheet and the third insulating sheet; the first insulating sheet, the second insulating sheet and the third insulating sheet are arranged in an inner cavity of the heat conduction aluminum pipe, an inner wall of the heat conduction aluminum pipe tightly presses the first insulating sheet, the second insulating sheet and the third insulating sheet, two ends of the second insulating sheet are respectively provided with connection terminals, and the connection terminals are respectively exposed from ports of the heat conduction aluminum pipe. The electric heater is simple and reasonable in structure and environment-friendly.

Description

technical field [0001] The invention relates to a resistance wire heater, in particular to an electric heater replacing a PTC heater. Background technique [0002] Household air conditioners, heaters, electric fireplaces, clothes dryers and other electric heating appliances that need to blow hot air are often equipped with PTC heaters. However, the PTC electric heater has 2-2.5 times the inrush current, and the PTC heating sheet is not environmentally friendly. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an electric heater using resistance wire heating. [0004] The above-mentioned purpose is achieved through the following technical solutions: [0005] An electric heater, comprising at least one heater, the heater includes a heating core, a heat-conducting aluminum tube, and a heat sink, and is characterized in that: the heating core includes a first insulating sheet, a seco...
