[0024] In order to make those skilled in the art more clearly understand the purpose, technical scheme and advantages of the present application, the following will be further described in conjunction with the drawings and examples.

[0025] In the description of the present application, it should be understood that the orientation or position relationship indicated by the terms "up", "down", "left", "right", "in", "out", "horizontal", "vertical" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application, and does not indicate or imply that the device or element referred to must have a particular orientation, therefore it cannot be understood as a limitation on the present application.

[0026] The present application will be described in detail below in conjunction with the drawings: as Figures 1-3 ​​As shown, a multi-level high-heat-dissipation PTC heating element is disclosed. The heating element consists of at least two heat dissipation strips 1 and a PTC heating block 2. At least one PTC heating block 2 is sandwiched between the two heating strips 1. Each heat dissipation strip 1 consists of a flat plate 3, a curved plate 4, and a heat dissipation corrugated strip 5. The flat plate 3 has a heat dissipation corrugated strip 5 welded to at least one side, and the curved plate 4 is welded to the side of the heat dissipation corrugated strip 5 away from the flat plate 3. The curved plate 4 has curved edges 6 on both sides, which wrap around the heat dissipation corrugated strip 5 and leave a certain heat dissipation gap 7 between it and the flat plate 3 below. The flat plates 3 of two adjacent heat dissipation strips 1 are welded together to form a heat dissipation edge. A terminal interface 8 is installed at one end of the heat dissipation edge. One side of the curved plate 4 is welded and fixed to the PTC heating block 2. The terminal interface 8 is connected to a neutral wire or at least one live wire. Heat is generated by turning on the neutral wire and at least one live wire.

[0027] This invention, through the heat dissipation gap between the curved edge and the flat plate below, can also improve the heat dissipation performance of the heating component during operation to a certain extent, thereby greatly improving the overall service life and stability during operation.

[0028] The heat dissipation strip 1 has at least three strips. The middle heat dissipation strip flat plate 3 has heat dissipation corrugated strips 5 and curved plates 4 installed on both sides. The two outermost heat dissipation strips 1 have heat dissipation corrugated strips 5 and curved plates 4 installed on opposite sides. At least three heat dissipation edges are formed by welding the flat plates 3 to each other and the curved plates 4 to the PTC heating block 2. Each heat dissipation edge is equipped with a terminal interface 8, one of which is connected to the neutral wire, and the remaining terminals are connected to the live wire. Multiple heating levels can be achieved by activating one neutral wire and one live wire, or one live wire. The heat dissipation corrugated strip 5 has a wave-shaped structure. The upper part is welded to the curved plate 4 via a top welding cap 9, and the lower part is welded to the flat plate 3 via a bottom welding cap 10. The welding cap 9 and welding cap 10 are composed of one or more of the following structures: U-shaped, triangular, V-shaped, and concave. Multiple heat dissipation windows 11 are also provided on the heat dissipation corrugated strip 5.

[0029] The multi-stage high heat dissipation PTC heating element designed in this utility model has a wave-shaped structure in the heat dissipation corrugations of each heat dissipation strip. The upper part is fixed to the curved plate by top welding, and the lower part is fixed to the flat plate by bottom welding. This can effectively ensure that each heat dissipation strip has good pressure resistance after installation.

[0030] like Figure 4 As shown, multiple heat dissipation windows 11 are provided and are evenly opened on the side of the heat dissipation corrugated strip 5. An air guide edge 12 is installed outside the heat dissipation window 11, and an arc-shaped lateral air guide 13 is opened on the air guide edge 12.

[0031] There are a total of 6 heat dissipation windows 11, with 3 on each side. Each heat dissipation window 11 is equipped with an air guide edge 12, and the arc-shaped air guide ports 13 on the air guide edges 12 on both sides are arranged in the same direction.

[0032] The PTC heating element designed in this utility model has heat dissipation windows on each PCT heat sink strip, and air-guiding edges with air inlets are set on the heat dissipation windows, which can increase the overall heat dissipation efficiency, thereby improving the overall service life and playing a role in air guiding, thus improving the heat dissipation effect. In addition, since graphene needs to be sprayed between the flat plate, curved plate and heat dissipation corrugated strip, the setting of heat dissipation windows can greatly improve its adhesion, thereby ensuring the overall stability after installation.

[0033] like Figures 5-6 As shown, a multi-stage annular heating coil is formed by bending the aforementioned multi-stage high-heat-dissipation PTC heating element, with its ends facing each other. A polygonal heating coil is also shown, formed by bending the aforementioned multi-stage high-heat-dissipation PTC heating element in multiple segments, with its ends facing each other. Of course, the multi-stage high-heat-dissipation PTC heating element of this invention can also be applied to other heaters without any limitation.

[0034] The specific embodiments described herein are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
