Abstract
A multiple-cavity PTC heater comprises a radiator main body made of an aluminium profile. the radiator main body is an elongated pipe provided with cavities, several ceramic heat-generating bodies and electrodes thereof are arranged in each cavity, the ceramic heat-generating bodies and the electrodes thereof are wrapped with an insulating layer, the end portion of each cavity is provided with a seal cover, the electrodes are led out from the seal cover to the exterior of the cavity, the interior of the radiator main body is provided with two or more than two side-by-side cavities, several ceramic heat-generating bodies and electrodes thereof are arranged in each cavity, the end portion of each cavity is provided with a seal cover, and the electrodes are led out from the seal cover to the exterior of the cavity. Compared to the prior art, the multiple-cavity PTC heater is advantaged in that by improving the profile of the radiator, the radiator is provided with a plurality of side-by-side cavities in order to overcome the problem that when the PTC heater works, the cavity is deformed due to tension forces, and the close-fitting effect is affected, and the using functions of the PTC heater are fulfilled and the service life of the PTC heater is prolonged.
Description
Technical field
The utility model relates to a kind of electric calorifie installation, especially the ptc heater of Multicarity.
Background technology
Instantly the application of ptc heater in various heating electrical appliances is more and more extensive, its structure conventionally as shown in Figure 1, comprise the radiator body that an aluminium section bar is made, radiator body is square pipe, there is a hollow cavity, the upper and lower surface of radiator body or wherein one side are provided with fin, and some ceramic heating elements are set in cavity, and its electrode is drawn from cavity end.Heating after ceramic heating element energising, heat is by the fin conductive on radiator body, for various heating electrical appliances.Such as warm-air drier, air-conditioning or water heater, refrigerant body is blown into from the gap of fin, and through fin, heat exchange can form hot media discharge.
Adopt said structure, ptc heater is in the time of work, due to the principle of expanding with heat and contract with cold, in cavity, can produce the close-fitting effect of tension set reduction internal components, once close-fitting is bad, will cause heat conduction efficiency to reduce, can directly affect use function and the life-span of ptc heater.
Utility model content
The purpose of this utility model is to break through the limitation of above-mentioned prior art, a kind of ptc heater of Multicarity is provided, by the improvement to its shaped material of radiator, make it have multiple cavitys side by side, while overcoming ptc heater work with this, the tension set of cavity internal cause affects the defect of close-fitting.
The technical solution of the utility model is as follows:
The ptc heater of Multicarity, comprise the radiator body that an aluminium section bar is made, radiator body is microscler tubing, there is cavity, some ceramic heating elements and electrode thereof are set in cavity, ceramic heating element and electrode thereof are wrapped up by insulating barrier, cavity end is provided with seal cover, electrode leads to cavity outside in seal cover, in radiator body, there is two or more cavitys side by side, in each cavity, be equipped with some ceramic heating elements and electrode thereof, cavity end is provided with seal cover, and electrode leads to cavity outside in seal cover.
After adopting said structure, ceramic heating element is dispersed and is distributed in multiple cavitys, and the ceramic heating element in each cavity can be combined closely with tube wall, the distortion that when the counteracting ptc heater that can try one's best is worked, cavity internal cause tension force produces.
Compared with prior art, the beneficial effects of the utility model are: by the improvement to its shaped material of radiator, make it have multiple cavitys side by side, while overcoming ptc heater work with this, the tension set of cavity internal cause affects the defect of close-fitting, has promoted use function and the life-span of ptc heater.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
Brief description of the drawings
Fig. 1 is the structural representation of prior art.
Fig. 2 is the structural representation of radiator body of the present utility model.
Embodiment
As shown in Figure 2, the ptc heater of Multicarity, comprise the radiator body 1 that an aluminium section bar is made, radiator body is microscler tubing, in radiator body 1, there is two or more cavitys 12 side by side, interior some ceramic heating elements and the electrode (scheming not shown) thereof of all arranging of each cavity 12, ceramic heating element and electrode thereof are by insulating barrier parcel (scheming not shown), cavity 12 ends are provided with seal cover (scheming not shown), and electrode leads to cavity 12 outsides in seal cover.
For a person skilled in the art, the structure that can disclose according to the utility model and principle obtain other various corresponding changes and distortion, and these all changes and distortion all belong to protection category of the present utility model.
