Abstract
The invention discloses a stacked high-power PTC heater. The stacked high-power PTC heater comprises a plurality of PTC ceramic heating bodies which are arranged in parallel to one another, two electrodes in contact with the PTC ceramic heating bodies, an insulating heat conduction film wrapping the two electrodes, and a metal pipe shell packaging the insulating heat conduction film, wherein each electrode comprises a main electrode body and a plurality of conductive fins which are arranged on one side of the main electrode body in parallel, conductive fins of the two electrodes are arranged in a mutually staggered manner, so that each PTC ceramic heating body is positioned between the two adjacent conductive fins. By adopting the structure, since the electrodes with the conductive fins are provided, the conductive fins are arranged in a mutually staggered manner and each PTC ceramic heating body is positioned between the two adjacent conductive fins, the power density is increased without enlarging the size during production process of high-power heaters, and the stacked high-power PTC heater is adapt to electric heating working condition with small installation space and high power requirements.
Description
Technical field
The present invention relates to a kind of ptc heater, specifically a kind of closed assembly High-Power PTC heater.
Background technology
Traditional ptc heater power density is less, will produce powerful heater respective volume also than larger, for peace
Dress space is little and needs not applying under powerful electrical heating operating mode.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of power greatly and the closed assembly High-Power PTC heater of small volume.
In order to solve above-mentioned technical problem, the closed assembly High-Power PTC heater of the present invention, including arranged in parallel more
Two electrodes that individual PTC-ceramic heater is contacted with PTC-ceramic heater, the insulating heat-conductive film of two electrode outer wrappings and
The Can being encapsulated in outside insulating heat-conductive film, two electrodes include a main electrode and parallel arrangement in main electrode one respectively
The more sheets of conductive fin of side, the interlaced arrangement of conductive fin of two electrodes simultaneously cause each PTC-ceramic heater point
Between two panels conduction fin that Wei Yu be not adjacent.
The length of the lateral length of each PTC-ceramic heater conductive fin more than per piece.
The upper end of the Can is fixedly installed insulated end cover, and the lower end of the Can is fixedly installed down
Insulated end cover.
The upper insulated end cover inner face and topmost one compression spring of setting between a plate electrode fin.
The inner face of the upper insulated end cover is additionally provided with locating shoulder, and the compression spring is fixed by locating shoulder placement
Position.
Between the insulating heat-conductive film and the outer surface and insulating heat-conductive film and the inner surface of Can of two electrodes
Gap location filling thermal plastic insulation.
Outside the Can, radiating fin is set.
After using above-mentioned structure, due to the electrode with conductive fin for arranging, conductive fin is interlaced to be arranged simultaneously
So that each PTC-ceramic heater is located at respectively between adjacent two panels conduction fin, thus in production high-power heater
During, power density is increased in the case where volume is not increased, adapted to less installing space and needed powerful
Electrical heating operating mode.
Description of the drawings
Fig. 1 is the structural representation of closed assembly High-Power PTC heater of the present invention.
Specific embodiment
With reference to the accompanying drawings and detailed description, the closed assembly High-Power PTC heater of the present invention is made further in detail
Explanation.
As illustrated, the closed assembly High-Power PTC heater of the present invention, sends out including multiple PTC-ceramics arranged in parallel
Hot body 1, the insulating heat-conductive film 3 of two electrodes, 2, two 2 outer wrappings of electrode contacted with PTC-ceramic heater 1 and it is encapsulated in
Can 4 outside insulating heat-conductive film, Can 4 is outer to arrange radiating fin 11, and the upper end of Can 4 is fixedly installed
Insulated end cover 7, the lower end of Can 4 are fixedly installed lower insulated end cover 8, two electrodes 2 include a main electrode 5 respectively with
And parallel arrangement, in the more sheets of conductive fin 6 of main electrode side, the interlaced arrangement of conductive fin 6 of two electrodes is simultaneously caused every
Individual PTC-ceramic heater 1 is located between adjacent two panels conduction fin 6 respectively.
By said structure, after installation, the side of each PTC-ceramic heater 1 is contacted with each main electrode simultaneously, each
The upper and lower end face of PTC-ceramic heater 1 and adjacent two panels conduction fin contacts, meanwhile, each PTC-ceramic heater it is horizontal
The length of length conductive fin more than per piece, the fin end portion thus, it is possible to avoid two fin electrodes are mutually touched and cause short circuit.
Further, the inner face of described upper insulated end cover 7 is additionally provided with locating shoulder, 7 inner face of upper insulated end cover
One compression spring 9 is set between one plate electrode fin of the top, and compression spring 9 is positioned by locating shoulder placement, so
When insulated end cover screw is tightened, can be by compression spring to the PTC-ceramic heater of all closed assemblies and conductive fin electrode
Between apply a pretightning force, make contact resistance and thermal resistance between conductive fin electrode and PTC-ceramic heater diminish.
Yet further, the outer surface and insulating heat-conductive film 3 and metal of described insulating heat-conductive film 3 and two electrodes 2
Gap location filling thermal plastic insulation 10 between the inner surface of shell 4.
