Abstract
Disclosed in the utility model is an internal tightly-extruding PTC heater comprising a PTC heater metal body. One or more PTC heating units are installed in the PTC heater metal body and are electrically connected with an external power supply by power lines; and the PTC heating units are installed inside the PTC heater metal body. Each PTC heating unit in the PTC heater is tightly extruded inside the PTC heater metal body by two or more than two pointed plugging sheets with opposite directions, wherein the pointed plugging sheets are arranged inside the PTC heater metal body. With the PTC heater, the emitted heat is transmitted to the internal surface or the external surface of the metal body to carry out heating on gas, liquid or a solid matter. The heating performance is excellent; the heat transfer power is high; and the PTC heating structure is suitable for various complex metal bodies.
Description
Technical field
The utility model relates to a kind of inner jam-packed formula ptc heater, more particularly, is that a kind of heat transfer is good, and conducted power is large, electric heating PTC heating element applied widely.
Background technology
Metal shell PTC heating element is in the past to adopt the in-built one or more PTC heating units of metal shell, and the periphery of extrusion metal shell, can be adjacent to PTC heating unit and metal shell.PTC heating unit is connected with external power supply by power line.In the time of need to using, PTC heating element is put into gas, the liquid or solid material that will heat, switched on power and heat.There is following defect in the PTC heating element of this structure: applicable metal body is insufficient, has a lot of metal bodies by this compression mode, can not meet the requirement of the metal body heating of labyrinth.
Metal shell PTC heating element in the past, also has the in-built one or more PTC heating units of the metal shell of employing, and PTC heating unit and metal shell not extruding are adjacent to, and between PTC heating unit and metal shell, have gap.PTC heating unit is connected with external power supply by power line.In the time of need to using, PTC heating element is put into gas, the liquid or solid material that will heat, switched on power and heat.There is following defect in the PTC heating element of this structure: heat conducting effect is poor, and the power ratio of conduction is lower, the requirement of the more high-power heating of can not satisfying the demand.
Utility model content
The purpose of this utility model is to overcome above-mentioned defect of the prior art, provides a kind of scope of application wider, and conducted power is high, the inside jam-packed formula ptc heater of the requirement of the more high-power heating of satisfying the demand.
For achieving the above object, the technical scheme that the utility model provides is as follows: a kind of inner jam-packed formula ptc heater is provided, comprise ptc heater metal body, in described ptc heater metal body, be equiped with one or several PTC heating units, this PTC heating unit is electrically connected to external power supply by power line, and described PTC heating unit is arranged on the inside of ptc heater metal body; Each PTC heating unit in described ptc heater is inner at ptc heater metal body by being installed in the pointed patch jam-packed of two of ptc heater metal body inside or two above opposite directions.
The beneficial effect of inner jam-packed formula ptc heater described in the utility model is: the pointed patch by two or two above opposite directions is inner at ptc heater metal body by PTC heating unit jam-packed, between PTC heating unit and heater metal body, there is no gap, strengthened heat-transfer effect.After the energising of PTC heating unit, the heat of generation, through ptc heater metal body, is transmitted to inner surface or the outer surface of ptc heater metal body, reaches the object of heated air, liquid or solid matter.Can be applicable to the ptc heater of complicated metal body, applied widely; Heat conduction, than very fast, can obtain larger conducted power.
Below in conjunction with drawings and Examples, inner jam-packed formula ptc heater described in the utility model is described further.
Accompanying drawing explanation
Fig. 1 is the longitudinal sectional view of inner jam-packed formula ptc heater described in the utility model;
Fig. 2 is the transverse views of inner jam-packed formula ptc heater described in the utility model.
Embodiment
Therefore the example of inner jam-packed formula ptc heater described in the utility model, do not limit protection range of the present utility model below.
With reference to Fig. 1, Fig. 2, a kind of inner jam-packed formula ptc heater is provided, comprise ptc heater metal body 1, in described ptc heater metal body 1, be equiped with one or several PTC heating units 2, this PTC heating unit 2 is electrically connected to external power supply by power line 6, and pointed patch 3 jam-packeds of each the PTC heating unit 2 in described ptc heater by being installed in two of ptc heater metal body 1 inside or two above opposite directions are in ptc heater metal body 1 inside.
Described PTC heating unit 2 is arranged on the inside of ptc heater metal body 1; Pointed patch 3 by the above opposite directions of two or two by PTC heating unit 2 jam-packeds in ptc heater metal body 1 inside, very close to each other between PTC heating unit 2 and ptc heater metal body 1.After 2 energisings of PTC heating unit, the heat of generation is transmitted to ptc heater metal body 1 inner surface 4 or outer surface 5 through ptc heater metal body 1, reaches heated air, liquid or solid matter.
Above-described embodiment is preferably execution mode of the utility model; 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 Essence of the present utility model and principle, substitutes, multilayer, simplification; all should be equivalent substitute mode, within being included in protection range of the present utility model.
