Abstract
The utility model discloses a high -power PTC heater of closed assembly. It include mutual parallel arrangement a plurality of PTC pottery heat -generating body, with the thermal insulation membranes and the metal tubes of encapsulation the thermal insulation membrane outside of two electrodes of PTC pottery heat -generating body contact, two outer parcels of electrode, two electrodes include respectively that a central electrode and parallel is arranged and electrically conduct the fin in the multi -disc of central electrode one side, two the mutual staggered arrangement of electrically conductive fin of electrode makes every PTC pottery heat -generating body be located respectively between two adjacent electrically conductive fins. After adopting foretell structure, because the electrode that has an electrically conductive fin that sets up, the electrically conductive mutual staggered arrangement of fin makes every PTC pottery heat -generating body be located respectively between two adjacent electrically conductive fins, puts the in -process of high -power heater into production from this, has increased power density under the condition that does not increase the volume, has adapted to to have less installation space and need powerful electrical heating operating mode.
Description
Technical field
The utility model relates to a kind of ptc heater, specifically a kind of closed assembly High-Power PTC heater.
Background technology
Conventional P TC heater power density is less, and it is also larger to produce powerful heater respective volume, little and inapplicable under needing powerful electric heating operating mode for installing space.
Summary of the invention
The technical problems to be solved in the utility model is to provide the large and closed assembly High-Power PTC heater that volume is little of a kind of power.
In order to solve the problems of the technologies described above, closed assembly High-Power PTC heater of the present utility model, comprise multiple PTC ceramic heating elements arranged in parallel, the insulating heat-conductive film of two electrodes contacted with PTC ceramic heating element, two electrode outer wrapping and the Can that is encapsulated in outside insulating heat-conductive film, two electrodes comprise a main electrode and the more sheets of conductive fin of parallel arrangement in main electrode side respectively, and the interlaced layout of conduction fin of two described electrodes also makes each PTC ceramic heating element lay respectively between adjacent two panels conduction fin.
The lateral length of each described PTC ceramic heating element is greater than the length of every sheet conduction fin.
The upper end of described Can is fixedly installed insulated end cover, and the lower end of described Can is fixedly installed lower insulated end cover.
Between described upper insulated end cover inner face and the top one plate electrode fin, a Compress Spring is set.
The inner face of described upper insulated end cover is also provided with locating shoulder, and described Compress Spring settles location by locating shoulder.
The outer surface of described insulating heat-conductive film and two electrodes and the gap location between insulating heat-conductive film and the inner surface of Can fill thermal plastic insulation.
Outside described Can, radiating fin is set.
After adopting above-mentioned structure, due to the electrode with conduction fin arranged, the conduction interlaced layout of fin also makes each PTC ceramic heating element lay respectively between adjacent two panels conduction fin, thus in the process of producing high-power heater, increasing power density when not increasing volume, having adapted to there is less installing space and having needed powerful electric heating operating mode.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model closed assembly High-Power PTC heater.
Embodiment
Below in conjunction with the drawings and specific embodiments, closed assembly High-Power PTC heater of the present utility model is described in further detail.
As shown in the figure, closed assembly High-Power PTC heater of the present utility model, comprise multiple PTC ceramic heating elements 1 arranged in parallel, two electrodes 2 contacted with PTC ceramic heating element 1, the insulating heat-conductive film 3 of two electrode 2 outer wrapping and the Can 4 be encapsulated in outside insulating heat-conductive film, radiating fin 11 is set outside Can 4, the upper end of Can 4 is fixedly installed insulated end cover 7, the lower end of Can 4 is fixedly installed lower insulated end cover 8, two electrodes 2 comprise a main electrode 5 and the more sheets of conductive fin 6 of parallel arrangement in main electrode side respectively, the interlaced layout of conduction fin 6 of two electrodes also makes each PTC ceramic heating element 1 lay respectively between adjacent two panels conduction fin 6.
Pass through said structure, after installing, the side of each PTC ceramic heating element 1 contacts with each main electrode simultaneously, the upper and lower end face of each PTC ceramic heating element 1 and adjacent two panels conduct electricity fin contacts, simultaneously, the lateral length of each PTC ceramic heating element is greater than the length of every sheet conduction fin, the fin end portion of two fin electrodes can be avoided thus mutually to touch and cause short circuit.
Further, the inner face of said upper insulated end cover 7 is also provided with locating shoulder, between upper insulated end cover 7 inner face and the top one plate electrode fin, a Compress Spring 9 is set, Compress Spring 9 settles location by locating shoulder, like this when tightening insulated end cover screw, can be given between the PTC ceramic heating element of all closed assemblies and conduction fin electrode by Compress Spring and apply a pretightning force, contact resistance and thermal resistance between conduction fin electrode and PTC ceramic heating element are diminished.
Again further, the gap location between said insulating heat-conductive film 3 and the outer surface of two electrodes 2 and the inner surface of insulating heat-conductive film 3 and Can 4 fills thermal plastic insulation 10.
