The electric heating elements and the current limiting device all adopt semiconductor function ceramic thermistors. The electric heating elements are formed by a parallel connection of flake PTC positive temperature coefficient thermistors, and are embedded into the radiation plate. The current limiting device is formed by a series connection of NTC negative temperature coefficient thermistors and electric heating elements. The utility model can provide different powers according to different environments and adapt to the environment automatically, and greatly improves radiation ability of the medium temperature radiator.
Description
Affiliated technical field
The utility model relates to a kind of radiant type electric heating appliance that is used for indoor heating, especially can provide warm radiator in the self adaptation of different capacity according to the varying environment temperature.
Background technology
At present, middle temperature radiator is the heater-type radiator that is made of as heating nichrome.Warm radiator in the heater-type is used for indoor heating and is difficult to accomplish power match because the influence that is subjected to the heating material behavior can only provide constant power, and the power young pathbreaker does not reach heating effect, and power greatly then wastes energy, and does not have an economy; The conduction of warm radiant type electric heater and convection current heat waste are bigger in the heater-type in addition, and radianting capacity is little, only can be used as the additional device of low temperature radiation heating, use the radiant heating effect relatively poor separately.
The PTC semistor is aspect heating class device high-power applications, connectivity problem by PTC and radiator is perplexed always, usually use the blower fan heat radiation, application as the auxiliary heating of air-heater and air-conditioning, all be to use its dynamic power, because such heater members is hidden installation, radiator can be charged, to guarantee temperature and to reduce thermal inertia, should insulate for exposed electric heater, the requirement that guarantees certain temperature again and reduce thermal inertia then is difficult to accomplish, is confined to the low-temp radiating device below 80 ℃ at present.
Summary of the invention
Can only provide the deficiency of constant power and radiation effect difference in order to overcome warm radiator in the heater-type, and the connectivity problem of High-Power PTC application facet and radiator, the utility model provides a kind of can provide different power according to different environment, environment there is self-reacting ability, and has improved middle temperature radiator radianting capacity greatly.
The technical scheme that its technical problem that solves the utility model adopts is:
Warm radiator in a kind of self adaptation, radiant panel is that the structural plane by aluminium alloy plate directly embeds heating and constitutes, be connected with metal shell by heat insulation support, heating and current limiting element all adopt semiconductor function ceramics thermistor, heating is made of the parallel connection of sheet PTC semistor, embed equably in the radiant panel, current limiting element is that the NTC negative tempperature coefficient thermistor is connected with heating.
The beneficial effects of the utility model are: the radiating surface surface temperature is constant, can provide power according to environment temperature, PTC element and NTC element are all the semiconductor function ceramics, belong to the directly-heated type heater element, owing to only use the static power of PTC element, not only there is not power attenuation, also increased the service life of device, become the semi-permanent mould device, overall structure is simple.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a cross-sectional view of the present utility model.
Fig. 2 is an electrical equipment connection layout of the present utility model.
Among Fig. 1,1, the aluminium alloy radiant panel; 2, metal shell; 3, heating; 4, connect support; 5, attachment screw.
Among Fig. 2,6, the NTC negative tempperature coefficient thermistor; 7, heating; 8, PTC semistor.
The specific embodiment
In Fig. 1, aluminium alloy radiant panel 1 outside is a radiating surface, and the inboard is a structural plane; In the structural plane side equally distributed T type pawl is arranged, be used to embed heating 3 and be connected support 4 formation structures connections.Heating 3 is by several PTC semistor parallel connections, and is made of C level or more high-grade insulating materials insulation.Metal shell 2 by attachment screw 5 be connected support 4 and be connected to become integral body.The space at metal shell 2 and aluminium alloy radiant panel 1 inboard disconnected support place is by filled thermal insulation materials.
In Fig. 2, NTC negative tempperature coefficient thermistor 6 constitutes series circuit with heating 7; Heating 7 is to be made of several PTC semistor 8 parallel connections; The quantity of PTC semistor 8 is that the K value by static general power that requires and PTC semistor 8 is determined.
Radiant panel is to embed heating by the structural plane of aluminium alloy plate to constitute, and is connected with metal shell by heat insulation support, leaks to prevent heat, and reduction is conducted and the convection current heat waste, thereby has improved radianting capacity; Heating adopts and is made of several PTC semistor parallel connections, utilize the static volt ampere of PTC, be that the PTC element resistance is along with ambient temperature changes and the characteristic of variation, make it that different power can be provided according to different environment, and the NTC negative tempperature coefficient thermistor of connecting on circuit is as current limiting element, to eliminate the big defective of PTC element dash current.Utilize the resistance-temperature characterisitic of PTC element, select the PTC element of suitable curie point, the radiating surface temperature is controlled at below 300 ℃, make its become in warm radiator, not only be applicable to the indoor heating system, can also use as the radiant heating device separately.
Providing the function of different capacity according to different environment temperatures, is that the material behavior by the PTC element is determined; The PTC semistor is in operating temperature range, and the power relation that changes with variation of ambient temperature is: δ-dissipation factor in δ=Δ P/ Δ T formula; Δ P-power changes; Δ T-variation of ambient temperature can provide the power of 2000W 12 ℃ the time as environment temperature, and environment temperature then only provides the power of 800W in the time of 18 ℃, thereby reaches the specific purposes that conform automatically.
The static power of warm radiator in the self adaptation should be adjusted the resistance of heating on request, because heating is to be made of several PTC semistor parallel connections, therefore presses R=1/ (1/R when design
1+ 1/R
2+ ... 1/R
