Problems solved by technology
The corrugated heat sink and heat conduction sheet are the heat dissipation strips of the heater. The silicone rubber layer on the heat sink will affect the heat transfer effect and reduce the electrothermal conversion efficiency of the heater. At the same time, although silicone rubber has high temperature stability, it will , placed in the air for a long time, the silicone rubber will also age, which will affect the connection reliability and service life of the heater itself

Embodiment Construction
[0010] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.
[0011] like figure 1 As shown, a schematic structural diagram of a preferred embodiment of a corrugated heat dissipation strip for a heater according to the present invention. A corrugated heat dissipation strip for a heater, comprising a corrugated heat dissipation fin 2, a layer of thermal conductive fin 3 is attached to one side of the corrugated heat dissipation fin 2, the side of the corrugated heat dissipation fin 2 away from the thermal conductive fin 3, and the thermal conductive fin 3 and the corrugated heat dissipation fin 2. There is a layer of aluminum foil 1 in between.
[0012] The heat conducting sheet 3 is welded with the corrugated heat si...

The invention relates to a corrugated cooling strip for a heater. The corrugated cooling strip comprises a corrugated cooling fin. The corrugated cooling strip is characterized in that a layer of heat-conducting fin is stuck to one side of the corrugated cooling fin; aluminium foils are respectively arranged at the side, which is far away from the heat-conducting fin, of the corrugated cooling fin and between the heat-conducting fin and the corrugated cooling fin; and the heat-conducting fin and the corrugated cooling fin are welded together via the aluminium foil. The corrugated cooling strip has the following beneficial effects that: the aluminium foils are arranged at the side, which is far away from the heat-conducting fin, of the corrugated cooling fin and between the heat-conducting fin and the corrugated cooling fin, so that the cooling strip has the advantages of good heat transfer effect and reliability in connection; and the cooling strip dispenses with chemical adhesives and has a simple machining process, so that the production cost is effectively reduced and environmental protection is facilitated.
Description
technical field [0001] The invention relates to a heat dissipation device, in particular to a corrugated heat dissipation strip for a heater. Background technique [0002] Corrugated heaters are widely used, especially as fan heaters in household and similar electrical products and equipment. These heaters all have cooling strips. The existing corrugated heaters, such as Chinese Patent No. 200820159847.4, are corrugated heaters, which have a heating body and corrugated fins attached to both sides of the heating element. One side of the body is attached with a layer of heat-conducting sheet, and the two sides of the heat-dissipating sheet are respectively coated with silicone rubber. The corrugated heat sink and the heat conduction sheet are the heat dissipation strips of the heater. The silicone rubber layer on the heat sink will affect the heat transfer effect and reduce the electrothermal conversion efficiency of the heater. If placed in the air for a long time, the sili...
