Abstract
The utility model discloses an electric heater, which comprises a box body, and an electric heating pipe, a heat radiation plate and a heat screening plate which are arranged inside the box body, wherein, the front surface or the side surface of the box body is provided with a temperature adjuster and a power-supply switch; an indication lamp is arranged inside the power-supply switch, and the electric heating pipe is fixed on the heat radiation plate and is contacted with the heat radiation plate in a thermal way, and the heat radiation plate adopts a concave-convex structure and is provided with a heat radiation fin and a reinforcing rib, and the heat radiation plate is fixed on the heat screening plate, and the heat screening plate is fixed on the box body through a heat screening washer. The electric heating pipe and the heat radiation plate are separated from the inner wall of the box body, so that the body can be prevented from being overheated; the heat radiation plate and the heat radiation fin increase the heat radiation area of the electric heating pipe, so that the hat of the electric heating pipe can be rapidly transferred to the exterior; the reinforcing rib not only can improve the strength of the heat radiation plate and can save the material of the heat radiation plate, but also can further improve the heat radiation effect.
Description
Technical field
The utility model relates to a kind of heater, relates in particular to a kind of electric heater.
Background technology
The electric heater of Shi Yonging in the market comprises casing and is fixed on the electric heating tube of cabinet wall that be provided with heat-insulation layer between electric heating tube and the cabinet wall, its electric heating tube is a light pipe.Such electric heater, owing to little its radiating effect that causes of surface area of electric heating tube is poor, the heat-insulation layer that is provided with between electric heating tube and the cabinet wall is for the heat that prevents electric heating tube is delivered on the box body wall, thereby more is unfavorable for the electric heating tube heat radiation.
The utility model content
The technical problems to be solved in the utility model provides a kind of electric heater of perfect heat-dissipating.
For addressing the above problem, electric heater of the present utility model comprises casing and is installed in the interior electric heating tube of casing that casing front or side are provided with thermoregulator and power switch, be provided with heat sink in the casing, electric heating tube is fixed on the heat sink and with heat sink and forms thermo-contact.
Heat sink is provided with radiating fin.Heat sink is provided with reinforcement.Heat sink can be concaveconvex structure.Can also be provided with thermal insulation board in the casing, heat sink is fixed on the thermal insulation board, and thermal insulation board is fixed on the casing by mounting bracket and heat insulating washer.Electric heating tube and heat sink can be provided with more than one group or two groups.Be provided with indicator lamp in the power switch.
After having adopted above structure, heat sink can outwards transmit the heat of electric heating tube rapidly, because the surface area of heat sink is far longer than the surface area of electric heating tube, has improved the radiating effect of electric heater.Fin heat radiation on the heat sink can further strengthen area of dissipation, improves radiating effect; Reinforcement not only can improve the intensity of heat sink, makes heat sink can adopt thinner material to make, thus economical with materials, and also reinforcement self has certain area, also can further improve radiating effect; Heat sink adopts concaveconvex structure can increase the intensity of heat sink, makes its not frangibility; Thermal insulation board can make electric heating tube and heat sink and cabinet wall thereof isolate mutually, avoids box body wall boiling hot excessively.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
