The shell is internally provided with a heating element and a first temperature sensor used for detecting a temperature of the heating element. The shell is externally provided with a second temperature sensor which detects a heated object. The shell is also provided with a heat dissipation device. The heating element, the first temperature sensor, the heat dissipation device, and the second temperature sensor are in electrical connection. According to the counter flow temperature control heater of the utility model, temperatures of a heating object and the heated object can be controlled through the two temperature sensors, controllability is good, reliability is high, security performance is high, and a service life is long.
Description
Technical field
The utility model belongs to the heater technical field, particularly a kind of convection type Temperature controlled heater.
Background technology
In the prior art, heater of a great variety, for example the patent No. is CN201020602110.2; Notification number is 201937869U; Name is called a kind of utility model patent of Temperature controlled heater, and this Temperature controlled heater includes pedestal, and electrothermal tube, power line, the thermostat of pedestal inserted in the end; Thermostat is provided with temperature-sensitive head; The electric heating element of electrothermal tube, thermostat, power line are electrically connected in series successively, and pedestal is the sealed insulation structure of entity encapsulation, and the end of electrothermal tube, power line introducing portion, thermostat all are positioned at pedestal; The temperature-sensitive head of thermostat is positioned at electrothermal tube one side in the pedestal and stretches out to expose and protrude from pedestal, and the connecting portion that the electric heating element of electrothermal tube, thermostat, power line are electrically connected in series successively all is positioned at pedestal.This Temperature controlled heater is owing to the just thermostat that is used to detect the heating object temperature that adopts, and the Controllable Temperature property of heater is poor, and poor reliability.
The utility model content
The purpose of the utility model is the deficiency that overcomes prior art, and biconjugate streaming Temperature controlled heater is provided, and this heater can be controlled the temperature of calandria and heating object through temperature sensor, and controllability is good, and reliability is high, and security performance is high.
In order to overcome above-mentioned technical purpose, the utility model is realized by following technical scheme:
The described convection type Temperature controlled heater of the utility model; Comprise housing; Be provided with heating element in the said housing, be provided with first temperature sensor that is used to detect temp of heating element in the said housing, said housing is provided with second temperature sensor of a detection heating object outward; Also be provided with heat abstractor on the said housing, said heating element, first temperature sensor, heat abstractor, second temperature sensor are electrically connected.
As the further improvement of above-mentioned technology, said heating element is the PTC heating element.
In the utility model, said heat abstractor is a fan, and it is installed on housing one side end exit.
In the utility model, after being connected in series, the said heating element and first temperature sensor be connected in parallel with fan, link to each other with power supply again with after second temperature sensor is connected in series.
Compared with prior art, the beneficial effect of the utility model is:
The described Temperature controlled heater of the utility model is owing to be respectively equipped with a temperature sensor inside and outside its housing; It can control the temperature of heating element itself and heating object preferably, and controllability is good, and reliability is high; Fail safe is good, can delay the useful life of heater itself greatly.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is done detailed explanation:
Fig. 1 is the described convection type Temperature controlled heater of a utility model schematic perspective view,
Fig. 2 is the decomposing schematic representation of above-mentioned Fig. 1;
Fig. 3 is the described convection type Temperature controlled heater of a utility model cutaway view;
Fig. 4 is the utility model circuit theory diagrams.
Embodiment
Like Fig. 1-shown in Figure 3; The described convection type Temperature controlled heater of the utility model comprises housing 1, is provided with heating element 2 in the said housing 1; Also be provided with first temperature sensor 3 that is used to detect temp of heating element in the said housing 1; Said housing 1 outer second temperature sensor 4 that is provided with a detection heating object also is provided with heat abstractor 5 on the said housing 1, and wherein heating element 2 is the PTC heating element; Said heat abstractor 5 is a fan, and it is installed on a side end exit of housing 1, and this fan blows to the heat of PTC heating element on the heating object.Second temperature sensor 4 is the temperature that detect heating object, and in the temperature range that jobbie need heat, the PTC heating element is started working, and is the object heating; First temperature sensor 3 is the temperature that detect calandria itself, and under the malfunctioning situation of heat abstractor, first temperature sensor 3 starts, and the PTC heating element quits work, and prevents that PTC calandria self-temperature is too high.
As shown in Figure 4; Said heating element 2, first temperature sensor 3, heat abstractor 5, second temperature sensor 4 are electrically connected; Specifically be to be connected in parallel with fan after the said heating element 2 and first temperature sensor 3 are connected in series, link to each other with power supply again with after second temperature sensor 4 is connected in series.
The described convection type thermostat of the utility model operation principle is:
In temperature is in the temperature range that jobbie need heat (for example: 8～15 ℃), second temperature sensor 4 starts, and the PTC heating element is started working, and is the object heating; Under the situation of heat abstractor 5 malfunctioning (being stalled fan); When PTC heating element self-temperature reached a certain degree of danger (＞45 ℃), first temperature sensor 3 started, and the PTC heating element quits work; Prevent that PTC calandria self-temperature is too high; The overtemperature protection performance is good, and is safe and reliable, can greatly prolong the useful life of heater itself.
The utility model is not limited to above-mentioned execution mode; Every spirit and scope that the various changes or the modification of the utility model are not broken away from the utility model; If these are changed and modification belongs within the claim and equivalent technologies model of the utility model, then the utility model also means and comprises these changes and modification.
