Abstract
The utility model relates to an electric heating plate, particularly a device used for family heating. A film resistance sheet is adopted by the electric heating plate to be served as the heating element, and a polyimide film is served as an insulating layer. Moreover, the electric heating plate is composed of a thin aluminium plate, a wave-shaped aluminum thin plate and slot aluminium, wherein, the surface of the slot aluminium is provided with small holes arranged uniformly and heat loss through convection holes composed of the wave-shaped aluminium thin plate to play the heat emission function. The electric heating plate has simple structure, low cost, and light weight, and is an auxiliary device for the family heating in the winter.
Description
The utility model relates to a kind of electric hot plate that is used for family's heating.
In existing family heating installation, mainly contain following several device, a kind of free convection formula electric heater that cries, it is equipped with one or more air inlet and outlet usually, and hot-air comes out with the free convection form by outlet, improve environment temperature, but shortcoming is to need oil to do intermediate medium when work, and dangerous, weight is big, complex structure needs to be equipped with attemperating unit in addition.Second kind is forced convertion formula fan heater, and this heater is to add electric fan in the heating back, forces cold air to be heated to form warm braw by heating, makes the air in room obtain heating up.Another is the hot body pharoid, this heater is the radiation that utilizes heater heat energy, reflection waits the device of effect distribute heat, last a kind of visible radiation heater that cries, it has one or more heater elements, after these elements reached stable state, surface temperature reached 650 ℃, by the radiation distribute heat.In the prior art, all there is a common drawback in these three kinds of heaters of back, are exactly the surface thermal load height, and the heat dissipation element life-span is short, also all needs temperature control device, complex structure in addition.
The purpose of this utility model provides a kind of simple in structure, and is with low cost, and safe in utilization, electric hot plate easily.
The utility model does not need intermediate medium (as oil) according to Natural Heat Convection formula principle, adopts the film resistor sheet to make heater element, makes insulator with Kapton, with thin aluminum sheet it is encapsulated then, clamps with two waveform aluminum thin plates at last.
Describe structure of the present utility model in detail below in conjunction with Fig. 1, Fig. 2.The utility model adopts film resistor sheet 1 to make heater element, making insulating barrier with Kapton 2 wraps up resistor disc 1, use thin aluminum sheet 3 with its encapsulation then, form chip, the two sides respectively clamps chip with one deck waveform aluminum thin plate 4 and 5 before and after chip then, with groove aluminium 6 its four frames encapsulation is fixed at last.There is aperture arranged in a uniform on groove aluminium 6 upper and lower surfaces, as the heat loss through convection hole.
The utility model is simple in structure, with low cost, and is in light weight, and can it be hung on the wall according to family's needs.The utility model is particularly suitable for north cold area, as a kind of auxiliary equipment of family's warming, brings great convenience to people's lives.
Fig. 1 is the utility model front view.
Fig. 2 is the utility model vertical view.
Fig. 3 is the partial enlarged drawing of Fig. 2.
Embodiment:
With the metal film of 0.05 millimeters thick, as the resistor disc heater element, adopt Kapton to make insulating barrier then, with 0.3 millimeters thick aluminium sheet it is encapsulated at last, form chip, make radiator in the chip outside with striking out corrugated aluminium sheet at last.Last electric hot plate is of a size of 785 millimeters * 340 millimeters * 18 millimeters (long * wide * thick), connects the 220V AC supply voltage, and power output is 800W.
Claims (2)
1, a kind of electric hot plate, it is characterized in that: film resistor sheet [1] is a heater element, with Kapton [2] film resistor sheet [1] is wrapped up, and then with thin aluminum sheet [3] with its encapsulation, form chip, the two sides respectively clamps chip with one deck waveform aluminum thin plate [4] [5] before and after chip, uses groove aluminium [6] that its four frames encapsulation is fixing at last.
2, electric hot plate according to claim 1 is characterized in that: there is aperture arranged in a uniform on the upper and lower surface of groove aluminium ［ 6 ］.
