Description
Technical field
The utility model relates to heating element, is specifically related to the not charged type PTC heater in a kind of surface.
Background technology
The heater that utilizes of air-conditioning, warmer etc. generates heat, then by fan, the heat of heater generation is blown in air, makes ambient air heating, reaches the object warming.Traditional heater is to consist of heating wire, quartz ampoule etc., and its heater members, owing to there being the rubescent appearance fire hazardous of high temperature etc., exists potential safety hazard, existing gradually by the gesture of PTC heater replacement.Existing PTC heater is divided into two kinds, the not charged type of surface charging type and surface, and along with country keeps the safety in production and advocates household appliances, surperficial uncharged heater structure sealing, have moistureproof dustproof effect, and whole device surface is not charged, improves fail safe.
Surface not charging PTC heater is powerful blowing and the uncharged PTC heater of radiator of needing of a class, the advantage such as have safe and reliable, power stability, noise is little, the life-span is long, mechanical strength is good.Because security performance is good, be mainly used on the high-power family expenses heater members such as cooling and heating air conditioner, warm-air drier, disinfection cabinet, drier.At present, the surface not structure of charging PTC heater is to be mainly arranged in aluminum pipe after PTC heater element is superscribed to insulating paper, the both sides of aluminum pipe are solidified and are pasted fin or fin by silica gel heating, make with PTC heater element and electrode strip, heat radiation place bonding curing after then processing by tube press machine pressure pipe.This structure installation procedure is many, and inconvenient operation because need first PTC heater element to be superscribed after insulating paper, then penetrates in aluminum pipe operation inconvenience; In addition, also need aluminum pipe to carry out pressure pipe processing, and will between fin and aluminum pipe, apply silica gel, fin is heating and curing.
Utility model content
The utility model will solve above-mentioned deficiency exactly, provides the simple surface of a kind of installation procedure not charged type PTC heater.
In order to reach above-mentioned effect, the utility model provides a kind of surface not charged type PTC heater, comprise PTC heater element, heat sink strip, and be welded on the electrode strip on PTC heater element, in the fixing hole that the centre that described PTC heater element embedding is located at fixture is offered, the both sides of described fixture are provided with U-shaped draw-in groove; Described electrode strip sticks on the both sides of PTC heater element, and described heat sink strip, by being connected with fixture in described U-shaped draw-in groove, is established insulating barrier between described electrode strip and heat sink strip.
The both sides, bottom surface of described heat sink strip are provided with the extension edge matching with the U-shaped draw-in groove of described fixture, and described heat sink strip is affixed by extension edge and fixture.
Described fixture comprises base plate, and described fixing hole is located at the centre of base plate, and the bilateral symmetry of base plate is provided with end plate, between the upper and lower surface of described end plate and base plate, forms U-shaped draw-in groove, and the thickness of described base plate is not more than the thickness of PTC heater element.
Surface of the present utility model not charged type PTC heater assembling mode is: first PTC heater element is embedded in the fixing hole on fixture base plate, and then respectively paste an electrode strip in the above and below of PTC heater element, in the outside of electrode strip, establish again the insulating barrier that an insulating material forms, finally successively the extension edge of heat sink strip is penetrated from the beginning to the end in the U-shaped draw-in groove of fixture both sides, through equipment, clamp fastening formation PTC heater part.
The utility model has adopted the fixture of special construction to fix PTC heater element, heat sink strip etc., by the connected mode such as embedding, buckle simply, all original papers is combined into one.Because not using aluminum pipe, can save PTC heater element poling, pressure pipe and heat sink strip energising and solidify three operations.And heat sink strip one side is without applying silica gel again, also can save coating process and the silica gel of heat sink strip, has saved cost.
PTC heater element of the present utility model adopts PTC thermal sensitive ceramics element, have that thermal resistance is little, heat exchange efficiency is high, the remarkable advantage of constant temperature, low-temperature heat, its power improves with the reduction of ambient temperature, ultralow temperature starts 40 degrees below zero and can as usual start, heat rapidly, can accomplish that dehumidifying do not lower the temperature, obtain three times of dehumidifier effects, continuous dehumidifying, frequent start-stop, energy saving.When meeting fan trouble stall, because can not get abundant heat radiation, power can sharply decline automatically, now the surface temperature of heater maintains and is limited to Curie temperature left and right (being generally 220 ℃), thereby " rubescent " phenomenon of unlikely generation electric heating tubing heater surfaces, has got rid of the hidden danger having an accident.Thermostat and fuse are housed on heating element, play double protection functions.
