Frost removal institute calorific requirement has engine to provide, but new-energy automobile does not have engine, it is therefore desirable to increase heater to mention
Heating load；The security feature that ptc heater has surface temperature constant, it has also become the mainstream of new-energy automobile heater.
Existing ptc heater is there are many problems, and first, most of product does not have waterproofing design, installs in practical application
The place of heater can paddle, and be easy to cause heater electric leakage, even short circuit.The product that nominally waterproof IP67 is designed on a small quantity,
The mode waterproof of connecting part encapsulating is used, encapsulating cannot be guaranteed absolutely not gap first, in addition repeatedly hot in heater
After swollen shrinkage, glue and aluminum pipe will appear cracking water inlet, so the practical waterproof effect of encapsulating mode is very poor, especially use one section
After time, the waterproofing grade of IP67 cannot be reached at all.
Second, traditional ptc heater is protected without puncture short, and PTC heater element works under normal voltage low probability
The breakdown of meeting quilt, causes short circuit.Since traditional ptc heater itself does not have any short-circuit protection, when puncture short, is easy to cause
It is on fire；
Third, traditional ptc heater are mostly withheld using copper with heat-generating pipe doubling and are connect, sent out on new-energy automobile using heater
Thermal power is larger, and generally 4 to 8KW, so a ptc heater is generally made of 5 to 8 PTC heating tubes, traditional PTC adds
Hot device is to save space, more PTC heating tube conducting wires by copper withhold the mode of connecing and at 1 main line, since core is excessive, and only
It is not tight etc. bad that core damage, crimping can be led to be easy to appear at doubling by holding operation.

PTC heat-generating pipe 1 mutually assembly after volume screw hole corresponding with 331 position of extension through-hole, by screw through extension through-hole 331 with
The screw hole is threadedly coupled, and realizes fixation between the two.
Integrated formed structure can be used between the extension 33 and the first support base 3, it can also be using in extension 33
It is equipped with the screw rod being arranged towards 3 direction of the first support base, correspondingly, through-hole is arranged in the corresponding position on the first support base 3,
It is threadedly coupled after screw rod is inserted into through-hole by nut, makes the fixation between extension 33 and the first support base 3.
Temperature controlling box 332 is also provided in extension 33.
As shown in Figure 1, being respectively equipped with the first company on both ends of first support base 3 far from a side surface of PTC heat-generating pipe 1
Fishplate bar 9, first connecting plate 9 are equipped with the first connecting hole 91；In a side surface of second support base 4 far from PTC heat-generating pipe 1
Both ends on be respectively equipped with the second connecting plate 92, on the second connecting plate 92 be equipped with the second connecting hole 93.
In the present invention, the first sealing ring 5, the second sealing ring 7 and third sealing ring 81 are all made of silica gel material and are made.
Beneficial effects of the present invention：The present invention uses silica gel part for primary sealing member, since silica gel has elasticity, heating
The thermal expansion coefficient of device each component during heating is inconsistent, and the elasticity of silica gel can just make up process of expansion and contraction, respectively
The gap generated between component (especially aluminum pipe and support base).So waterproof described in this product, being can be in room temperature and fever
Process can accomplish waterproof effect.
The present invention is provided with overcurrent protective device and/or temperature controller, is equivalent to included overcurrent protection and overheating protection；And mistake
The type selecting of stream safety device and/or temperature controller more matches the characteristic of ptc heater, and further overcurrent insurance is designed at every PTC
On heat-generating pipe, most rapid protection is played, risk control to minimum.
On the first sealing ring, product can play certain PTC heat-generating pipe weight bearing of the invention when vehicle is run
Antihunt action, product can be reduced to a certain extent and loosened, or deformation the case where.
5% or more the sealing means loss of weight of Seal Design intersection encapsulating of the invention, such design meet automotive-type portion
The main trend of part loss of weight.
