Description

A kind of New PTC heater

Technical field

The utility model relates to a kind of New PTC heater.

Background technology

China Patent No.: 201520034632.X discloses a kind of ptc heater, comprise the heat conduction support being placed in metal outer pipe inside, heat conduction support is provided with multiple axial containing cavity, each containing cavity is built with PTC fever tablet, PTC fever tablet Surface coating insulating case, PTC fever tablet has close to one end of terminal box the lead-in wire electrode stretching out insulating case, lead-in wire electrode with stretch into the power line that wiring closes and be electrically connected.Utilize the constant temp. warming characteristic of PTC fever tablet, PTC fever tablet powers up rear self-heating and heats up, resistance enters transition district, can the change of environmentally temperature the thermal power of self be regulated to export, PTC fever tablet surface temperature is made to keep steady state value, can by the power consumption optimal control of heater minimum, the thermistor material of high heating efficiency also significantly improves the utilization ratio of electric energy simultaneously, and in the situations such as heater dry combustion method and thermostat exception, also heat-generating pipe is there will not be to burn the phenomenons such as red, pipe punctures, can prevent fire from occurring, and improve the life-span of heater.But this ptc heater structurally also exists a little deficiency, its parts are more, and production, assembling comparatively bother, and because problems such as build-up tolerances, often easily occur that parts loosen.

Utility model content

Therefore, for above-mentioned problem, the New PTC heater that the utility model proposes that a kind of structure is simple, easy accessibility, production and processing are simple, can save production cost.

For achieving the above object, the utility model have employed following technical scheme: a kind of New PTC heater, comprise metal outer pipe, aluminium section bar, PTC fever tablet, positioning aluminium leads to, described PTC fever tablet is coated with an insulating case, described aluminium section bar is provided with the containing cavity of a plurality of accommodating PTC fever tablet, described positioning aluminium leads to the location lug being provided with holding PTC fever tablet, heat conduction copper sheet is provided with between described insulating case and location lug, the two ends described aluminium section bar being positioned at the opening part of containing cavity are respectively equipped with elasticity clip piece, described elasticity clip piece forms linear contact lay near curved itself and the heat conduction copper sheet of making of one side of heat conduction copper sheet.

Further, the position of madial wall relative positioning tenon that described positioning aluminium leads to offers a plurality of radiating groove.

Further, the two ends, left and right being positioned at PTC fever tablet in described containing cavity are respectively equipped with elasticity holding head, and there is gap between described elasticity holding head and insulating case, gap is less than 0.5mm.

Further, the free end of described elasticity holding head is provided with a circular jacking block.

Further, higher than location lug surface 0.1 ~ 0.5mm when described elasticity clip piece is in initial condition.

By adopting preceding solution, the beneficial effects of the utility model are: this New PTC heater, by arranging elasticity clip piece, thus ptc heater can be stable in containing cavity, and PTC heating plate that production tolerance the brings bad problem such as built on the sand can be got rid of, and eliminate aluminium patch, namely cost-saving, also one-shot forming when extruding can be utilized to reduce production craft step, make whole production, assembling more simple, dismantle also more simple; Further, by arranging radiating groove, the better effects if of dispelling the heat can be made, also reduce the use amount of material simultaneously, cost-saving; Further, by arranging elasticity holding head, further can reduce the fixing of PTC heating plate, thus making contact better, namely radiating effect is better, and is provided with gap, and is less than 0.5mm, difficulty can not be brought to assembling, also can realize holding, and not destroy the outer surface of insulating case; Further, by arranging circular jacking block, location better can must be realized; Further, higher than location lug surface 0.1 ~ 0.5mm when elasticity clip piece is in initial condition, when PTC heating plate and copper sheet can be made to install, can first contact resilient clip piece, thus utilizing elasticity clip piece as main holding position, the Main Function of location lug is then heat trnasfer heat radiation.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

Now with embodiment, the utility model is further illustrated by reference to the accompanying drawings.

With reference to figure 1, the present embodiment provides a kind of New PTC heater, comprise metal outer pipe 1, aluminium section bar 2, PTC fever tablet 3, positioning aluminium logical 4, described PTC fever tablet 3 is coated with an insulating case 5, described aluminium section bar 2 is provided with the containing cavity 21 of six accommodating PTC fever tablets 3, described positioning aluminium leads to the location lug 41 that 4 are provided with holding PTC fever tablet 3, heat conduction copper sheet 6 is provided with between described insulating case 5 and location lug 41, the two ends described aluminium section bar 2 being positioned at the opening part of containing cavity 21 are respectively equipped with elasticity clip piece 22, described elasticity clip piece 22 forms linear contact lay near curved itself and the heat conduction copper sheet 6 of making of one side of heat conduction copper sheet 6.The position that described positioning aluminium leads to the madial wall relative positioning tenon 41 of 4 offers a plurality of radiating groove 42.The two ends, left and right being positioned at PTC fever tablet 3 in described containing cavity 21 are respectively equipped with elasticity holding 23, and described elasticity holding exists gap between 23 and insulating case 5, and gap is less than 0.5mm.The free end of described elasticity holding 23 is provided with a circular jacking block 231.Higher than location lug surface 0.5mm when described elasticity clip piece 22 is in initial condition.
