Description
Technical field:
The utility model relates to a kind of high leakproofness ptc heaters.
Background technique:
What ptc heater typically worked in the case where environment is relatively more severe, such as air is heated, and in air
Often contain moisture, sometimes moisture content is quite high, and this requires ptc heater sealing performances must satisfy under above-mentioned condition
It uses.Gap of the ptc heater sealing of traditional structure only between PTC fire-bar and positioning end seat simply applies daub
Water, this sealing structure reliability is excessively poor, because sealing is only sealed for surface layer, seal failure phenomenon often occurs, causes
The generation of electric leakage.
Summary of the invention:
The shortcomings that the purpose of this utility model is to overcome the above-mentioned prior arts provides a kind of sealed reliable, safety
High ptc heater can satisfy IP67 class requirement in automobile water protection standards.
The goal of the invention of the utility model can be realized by technical solution below: a kind of high leakproofness PTC heating
Device includes a plurality of parallel aluminum pipe, PTC heating strip and ripple bar, and aluminum pipe is hollow structure, and PTC heating strip is placed in aluminum pipe,
Ripple bar is arranged between adjacent two aluminum pipe, and the both ends of aluminum pipe are provided with positioning end seat, positions and forms in end seat and aluminum pipe
The location hole that shape matches, aluminum pipe end pass through location hole, position and form storage glue groove on the outside of end seat, fill in storage glue groove
The opening of sealant, storage glue groove is equipped with end cap, wherein being equipped with isolating bar in the storage glue groove of a positioning end seat, the two sides of isolating bar are set
There is an electrode strip, corresponding aluminum pipe end is equipped with connecting terminal, and connecting terminal and electrode strip are at being electrically connected.
There is positioning to pick up the ears toward elongation moulding in the middle part of aluminum pipe in the two sides of positioning end seat.
After the technical program, compared with prior art, the technical program is had the advantage that by positioning end seat
Inside setting storage glue groove, is poured glue in storage glue groove, is sealed processing from the inside to the outside, and triple waterproofs are arranged in the present invention and come
Guarantee that PTC heater is impermeable.To greatly improve the overall sealing performance of product, sealing effect is very reliable.
Detailed description of the invention:
Fig. 1 is the three-dimensional structure diagram of the utility model high leakproofness ptc heater；
Fig. 2 is the dimensional decomposition structure figure of the utility model high leakproofness ptc heater；
Fig. 3 is the sectional structure chart of the utility model high leakproofness ptc heater.
Specific embodiment:
This technology is described further with reference to the accompanying drawing.
The high leakproofness ptc heater of the present embodiment includes a plurality of parallel aluminum pipe 1 and PTC heating strip 2, during aluminum pipe 1 is
Hollow structure, PTC heating strip 2 are placed in aluminum pipe 1, and the both ends of aluminum pipe 1 are provided with positioning end seat 3, positions and forms in end seat 3
The location hole 4 to match with 1 shape of aluminum pipe, aluminum pipe end pass through location hole 4, and the outside of positioning end seat 3 forms storage glue groove 5,
Sealant is filled in storage glue groove 5, the opening of storage glue groove 5 is equipped with end cap 6, wherein being equipped with isolation in the storage glue groove 5 of a positioning end seat
The two sides of item 7, isolating bar 7 are equipped with electrode strip, are anode electrode item 81 and negative electrode item 82 respectively, corresponding aluminum pipe end is set
There are two connecting terminals, is positive terminal 91 and negative terminal 92 respectively, injects storage glue in 1 end of PTC heating strip
After in slot 5, the connecting terminal in storage glue groove 5, at being electrically connected, glue is perfused in storage glue groove 5, then covers with electrode strip
End cap 6, after glue curing, sealed nature is formed, and ripple bar 10 is arranged between adjacent two aluminum pipe 1.In positioning end seat 3
Two sides there is positioning to pick up the ears 11 toward 1 middle part elongation moulding of aluminum pipe, pick up the ears 11 presence of positioning can be played entire ptc heater is determined
Position wraps up, and improves intensity and packaging efficiency.
3 interior design of positioning end seat of this technology storage glue groove 5, it is past after the end of PTC heating strip 1 is injected in storage glue groove 5
Glue is injected in storage glue groove 5, glue gets up the entire end part seal of PTC heating strip 1 being located in storage glue groove 5, and sealing performance is not
It says and explains, obtain the leakproofness of superelevation.The experiment proved that product is put into impregnated 48 hours in one meter of deep water after take, it is ensured that produce
Product will not lead to electric leakage because of infiltration.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation.Anyone skilled in the art, it is all available in the case where not departing from technical solutions of the utility model ambit
The methods and technical content of the disclosure above makes many possible changes and modifications to technical solutions of the utility model, or is revised as
The equivalent embodiment of equivalent variations.Therefore all contents without departing from technical solutions of the utility model, the shape according to the utility model
Equivalence changes made by shape, construction and principle should all be covered by the protection scope of the utility model.
