Description
Technical field
The utility model relates to a kind of exothermic material, relates in particular to a kind of novel aluminium oxide ceramics heating plate with the high sensitivity temperature sensor.
Background technology
Prior art mainly comprises as the exothermic material of electric heating appliance: electrothermal tube and PTC positive temperature coefficient thermal sensitive ceramic material.
The PTC thermal sensitive ceramic material has a lot of excellent specific properties, and it has from characteristics such as temperature control, the safe flames of angers, has therefore replaced electrothermal tube in a large number, obtains extensive use.But there is following shortcoming in the PTC thermal sensitive ceramics in actual application:
1. contain Toxic matter-lead.For improving the power of PTC thermal sensitive ceramic material, generally add the Curie temperature that a large amount of lead improves material therein.In the manufacturing process of thermal sensitive ceramic material and discarded material, all can cause plumbous pollution, because lead is very harmful to the people's, according to the command request of forbidding noxious substance in instruction of WEEE waste electronic electric equipment and the ROHS electronic and electrical equipment, to the leaded electronic material that waits noxious substance of forbidding in 2006.
2. power aging.Because the characteristic of PTC ceramic material makes it the aging bigger of PTC ceramic heater, if under switching on stuffy situation in 1000 hours, the PTC ceramic resistor is aging generally to reach 30%, and power aging generally reaches about 10%.
3. power density is little.General Curie temperature is that 250 ℃ PTC thermal sensitive ceramics heater is being forced under the cooling condition, and maximum power density has only 40W/cm2.

At such situation, company of Kyocera has released the aluminium oxide ceramics heater, and domestic also have producer to begin small lot batch manufacture, and it has solved the shortcoming of PTC thermal sensitive ceramics, obtains a large amount of application rapidly in hair waving pin market.
But compare with the PTC thermal sensitive ceramics, the aluminium oxide ceramics heater comes with some shortcomings again, the aluminium oxide ceramics heater does not have the automatic controlled function of temperature, and temperature can raise until reaching hygral equilibrium always in use, therefore in use temperature control wiring board and temperature sensor must be installed.Yet traditional temperature sensor is to adopt NTC negative temperature coefficient temperature sensor, so the shortcoming of aluminium oxide ceramics heater below existing in actual application:
1. thermal coupling is poor, and response speed is slow.General N TC temperature sensor adopts glass packaging or epoxy resin enclosed, so the temperature sensor heat transfer is slow, does not catch up with the firing rate of aluminium oxide ceramics heater, makes it to cause easily temperature control.
2. temperature-measuring range is little.Because the highest probe temperature of NTC temperature sensor is less than 250 degree, therefore if probe temperature is spent greater than 250, the structure of NTC transducer will be damaged.
3. the non-uniform temperature of heating plate.Because the temperature height of aluminium oxide ceramics heater middle part, the temperature of edge is low, therefore causes the fracture of aluminium oxide ceramics easily.
4. install inconvenient.
