Description
Technical field
The utility model relates to heater technical field more particularly to a kind of PTC heating units with radiator.
Background technique
There are two main classes for heater on the market at present, and one kind is the heater using alloy resistance wire as pyrotoxin, such as electricity
Heat pipe, MCH, heating film etc., such heater is due to constant power output, and dry combustion method temperature can continue to rise, and up to thousands of degree are deposited
In larger security risk；Another kind of is PTC heater, and PTC heater has the advantages of surface constant temperature, but since unit area generates heat
Power is small, can not apply in some space-constrained heating arts, and PTC heater is mostly adhesive structure, structural strength is poor.
Conventional heater has the disadvantage that:
1, alloy resistance wire class heater temperature is high, safety is poor
Golden resistance wire is the heater of pyrotoxin, such as electrothermal tube, MCH, heating film, such heater be defeated due to invariable power
Out, dry combustion method temperature can continue to rise, and up to thousands of degree, there are larger security risks；
2, traditional ptc heater unit area power is small
Traditional ptc heater unit area maximum heating power 20W/CM2 can not be applied to big in some space small-powers
Application in.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, it is big to provide a kind of per unit area heater power, peace
The high PTC heating unit with radiator of full property.
The technical solution of the utility model is as follows: a kind of PTC heating unit with radiator, including PTC heating matrix, institute
The two sides for stating PTC heating matrix are provided with metal electrode board, and the two sides of the metal electrode board are provided with metal and Ceramic Composite
One end of structured heat sink, the metal and ceramic composite structures radiator is equipped with grafting female end, the metal and Ceramic Composite
The other end of structured heat sink is equipped with the grafting male end to match with the grafting female end.
In the above technical solution, the metal and ceramic composite structures radiator include two metallic heat radiating plates and
Two insulating ceramicses, the area of the metal electrode board is equal with the lateralarea of the PTC heating matrix, described two insulation
Ceramics are separately positioned on the lateral surface of the metal electrode board, and surround the PTC heating matrix and metal electrode board, and described two
A metallic heat radiating plate is separately positioned on the lateral surface of the insulating ceramics, and the area of the metallic heat radiating plate and the insulation are made pottery
The lateralarea of porcelain is equal, and one end of described two insulating ceramicses is respectively equipped with a grafting female end, described two insulation potteries
The other end of porcelain is respectively equipped with a grafting male end.
In the above technical solution, the thickness of the metal electrode board is more than or equal to 8mil.
In the above technical solution, the unit area heating power of the PTC heating unit is 100W/CM2.
Compared with the existing technology, the utility model has the beneficial effects that:
(1) because being provided with metal and ceramic composite structures radiator in the two sides of PTC heating matrix, when so that being powered on
The central temperature of PTC heating matrix is lower, its central temperature lower than traditional ptc heater nearly 50 under identical operating condition
DEG C, without dash current, and the equally characteristic of holding tradition PTC self-constant temperature when radiating failure；
It (2) can be by grafting male end and the grafting parallel with one another of grafting female end, to realize high-power between PTC heating unit
Application；
(3) for its unit area heating power up to 100W/CM2, heating power is traditional ptc heater maximum power 20W/
5 times of CM2.
