Abstract
The utility model provides a kind of high temperature INTELLIGENT PTC electric heater, comprises housing and inner chamber, and case top and bottom are engraved structure, and remainder is hermetically-sealed construction; Enclosure interior is connected with safe thermal insulation board; Inner chamber comprises PTC thermistor, insulation board and heat sink.Described PTC thermistor is oxide ceramic material.The beneficial effects of the utility model are, the thermistor adopting high-curie temperature is Heating body, and based on convection heat transfer' heat-transfer by convection, radiant heat transfer is that auxiliary mode is dispelled the heat, and have the feature of environmentally variations in temperature adjustment heating power, serve energy-conservation advantage.The scald that the safe thermal insulation board arranged can avoid child's false touch to cause, serves safe effect.
Description
Technical field
The invention belongs to electric heater field, especially relates to a kind of high temperature INTELLIGENT PTC electric heater.
Background technology
Existing electric heater adopts oils as heat-conducting medium mostly, using wire or resistance wire as calandria.Slowly, heat-conducting effect is low, wastes energy in this electric heater heating-up temperature change.The mode of the heat blowout heat radiation that some electric heaters adopt fan to be produced by calandria, noise is large, and power consumption is high simultaneously.Existing electric heater does not all have the safety prevention measure for the shorter child of height or handicapped people design simultaneously, although people can not scald by electrically heated temperature at short notice, but for the child born a pretty, delicate skin or handicapped people, probably cause low temperature to scald.
Summary of the invention
The problem that the invention will solve is, provides a kind of high temperature INTELLIGENT PTC electric heater, and be especially applicable to solving the heat-conducting effect existed in prior art poor, energy-saving effect is poor, and noise is large, the problem that safety coefficient is low.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is:
There is provided a kind of high temperature INTELLIGENT PTC electric heater, comprise housing and inner chamber, case top and bottom are engraved structure, and remainder is hermetically-sealed construction; Enclosure interior is connected with safe thermal insulation board; Inner chamber comprises PTC thermistor, insulation board and heat sink.
Further, described PTC thermistor is oxide ceramic material.
The advantage that the invention has and good effect are: the thermistor adopting high-curie temperature is Heating body, based on convection heat transfer' heat-transfer by convection, radiant heat transfer is that auxiliary mode is dispelled the heat, and has the feature of environmentally variations in temperature adjustment heating power, serves energy-conservation advantage.The scald that the safe thermal insulation board arranged can avoid child's false touch to cause, serves safe effect.

Detailed description of the invention
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the invention.
The invention adopts the PTC ceramic thermal resistance of high-curie temperature (280 DEG C-360 DEG C) to be calandria, heat sink is not directly connected with power supply with housing, radiating mode is convection heat transfer' heat-transfer by convection is main, heat loss through radiation is auxiliary, air directly enters in cavity and contacts with PTC thermistor, do not have heat transfer medium, directly spread out of after air is heated, thermal transition efficiency is high.In heating process, time PTC thermistor temperature is higher than Curie temperature, its resistance value sharply increases 102-108 doubly left and right, only balances with weak current maintaining heat.Give full play to the characteristic that PTC thermistor varies with temperature adjustment heating power automatically in heating process, reach energy-conservation object.The engraved structure at housing bottom and top is that the flowing of air provides passage.Safe thermal insulation board can by switch control rule, and when Environmental security, safe thermal insulation board is closed, and the both sides of housing also participate in heat radiation, reach the object of heating fast, when needs safety is heat insulation, open safe thermal insulation board, now housing both sides do not participate in heat radiation, and the temperature remains within the normal range, avoids false touch to cause low temperature to scald.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
