Abstract
The utility model discloses a PTC (Positive Temperature Coefficient) constant-temperature heating element comprising a heating resistor body, two split metal conducting layers (namely, a first metal conducting layer and a third metal conducting layer) adhered to one surface of the heating resistor body, and a second metal conducting layer adhered to the other surface of the heating resistor body, wherein the first metal conducting layer, the heating resistor body and the second metal conducting layer form a constant-temperature heating unit; the third metal conducting layer, the heating resistor body and the second metal conducting layer form another constant-temperature heating unit; the two constant-temperature heating units are connected in series to form a combination constant-temperature heating element; a power supply conducting wire is led out from the same surface of the first metal conducting layer and the third metal conducting layer; and the second metal conducting layer is connected with a heat conductor for transmitting heat outside. The PTC constant-temperature heating element greatly improves both the heat conduction efficiency and the heat usage rate, and saves the energy.
Description
Technical field
The utility model relates to a kind of architecture advances of PTC heated at constant temperature element.
Background technology
Traditional heated at constant temperature element is a kind of heating element commonly used, be by heating resistor, with constitute attached to two metal conducting layers of heating resistor the surface, power lead is drawn from two metal conducting layers to the surface respectively, and the outbound course of electric wire has two kinds: a kind of is to contact two metal conducting layers to the surface respectively with two sheet metals; Another kind be with two wire bonds (or bonding) at two metal conducting layers to the surface, the first method complex structure, volume is big, wiring is also inconvenient; Second method makes metal conducting layer all out-of-flatnesses of two surfaces up and down, thereby metal conducting layer can not fully closely be contacted with heat carrier, causes heat transfer efficiency low, is unfavorable for energy savings.
The utility model content
The purpose of this utility model is to overcome above-mentioned defective of the prior art, and a kind of energy savings, the convenient heated at constant temperature element of installing are provided.
For achieving the above object, the technical scheme that the utility model provides is as follows: a kind of PTC heated at constant temperature element is provided, comprise that attached to heating resistor one lip-deep first metal conducting layer, the 3rd metal conducting layer, attached to another lip-deep second metal conducting layer, first metal conducting layer, heating resistor and second metal conducting layer form a heated at constant temperature unit; The 3rd metal conducting layer, heating resistor and second metal conducting layer form another heated at constant temperature unit; These two heated at constant temperature units in series connect, and form the heated at constant temperature element of a combination, and two power leads are drawn from same surface.
The beneficial effect of PTC heated at constant temperature element described in the utility model is: by with described power lead, draw from first metal conducting layer the 3rd metal conducting layer respectively, because power lead is to draw from same surface, make another surface closely to contact with heat carrier fully, improved the heat transfer efficiency of heat carrier greatly, the convenient installation.
Lower surface is described further PTC heated at constant temperature element described in the utility model in conjunction with the accompanying drawings and embodiments.
Description of drawings

Fig. 2 is the vertical view of PTC heated at constant temperature element cutaway view described in the utility model.
Embodiment
Below be the preferred example of PTC heated at constant temperature element described in the utility model, therefore do not limit protection range of the present utility model.
With reference to Fig. 1, a kind of PTC heated at constant temperature element is provided, comprise attached to heating resistor 2 one lip-deep first metal conducting layers 1, the 3rd metal conducting layer 4, form a heated at constant temperature unit attached to another lip-deep second metal conducting layer, 3, the first metal conducting layers 1, heating resistor 2 and second metal conducting layer 3; The 3rd metal conducting layer 4, heating resistor 2 and second metal conducting layer 3 form another heated at constant temperature unit; These two heated at constant temperature units in series connect, form the heated at constant temperature element of a combination, power lead is drawn from same table surface, making heating resistor 2 to form surface of good with heat conduction body surface surface contacts, improved the heat transfer efficiency of heat carrier greatly, the heat utilization efficiency height helps energy savings.Simultaneously simple in structure, install easily.
The foregoing description is the utility model preferred implementation; but execution mode of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under spirit of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection range of the present utility model.
