Description
Technical field
The present invention relates to a kind of air-conditioning ptc heater housing with upper cover, especially a kind of air-conditioning ptc heater shell
Body.
Background technology
PTC (abbreviation of Positive Temperature Coefficient) refers to the quasiconductor that positive temperature coefficient is the biggest
Material, its main uses can be divided into switch and heating two big classes, utilizes heating class PTC stable performance, heats up rapidly, by power supply electricity
The features such as pressure influence of fluctuations is little, have the most been widely used for the auxiliary heating in winter, have been that existing air-conditioning must an obligato part.
PTC air-conditioning heater is to utilize this feature of PTC thermistor constant temp. warming to carry out the heater element related to, and has
Thermal resistance is little, the advantage that heat exchange efficiency is high, but owing to a lot of air-conditioning ptc heaters cannot be timely automated when air-conditioning draught fan stall
Quit work, potential safety hazard can be caused, in electric property, particularly there is potential safety hazard.Because PTC is thermostatical heating element, long
The dry combustion method of time can cause temperature in chassis higher, even can initiation fire, the installation of air-conditioning ptc heater is insecure too
Can easily send out security incident, existing shell structure cannot fix the movement time of protector and fuse-link.And this existing knot
Structure processing technology is loaded down with trivial details, and security reliability is poor, pretty troublesome time fixing, and cost is high, and production efficiency is low, and structure still needs to optimize.
Summary of the invention
It is an object of the invention to for above-mentioned present situation, it is desirable to provide a kind of life-span length, lightweight, stable and reliable operation, protect
Protect the stable action time of device and fuse-link, good waterproof performance, the PTC air-conditioning heater shell that the assembling with air-conditioner host fits together perfectly
Body.
The implementation of the object of the invention is, a kind of air-conditioning ptc heater housing, housing has upper cover, has above covered spiral shell
Nail one；The buckle of fixing thermal protector position is had on housing；The locating dowel by thermal protector root, fixing fusing is had in housing
The location tongue of body, the dividing plate of isolation ptc heater exit both positive and negative polarity, dividing plate has the screw hole matched with screw hole one
Two；Housing Base is fixed on air-conditioner host installing hole, cylinder locating dowel.
Using the present invention, ptc heater inserts in housing, and top is stuck with buckle.Thermal protector root is leaned against location
On post, fuse-link is fixed on tongue, and the both positive and negative polarity of ptc heater exit is separated by dividing plate, then is incited somebody to action by screw, screw hole
Upper cover is connected as a single entity with housing.
The present invention solves existing air-conditioning ptc heater protector and fuse-link is unstable for movement time, it is impossible to carry out water
Protection, fixes untight problem with mainframe box.
Compared with prior art, advantages of the present invention is as follows:
1, the thermal protector of assembling can be fixed by the projection at locating dowel and the upper cover back side, and thermal protector is heated evenly, dynamic
Make the time stable；
2, the tongue of thermal fuse-link position and the projection at the upper cover back side, specify that the rigging position of fuse-link, fuse-link with
Tongue fits together perfectly, and is heated evenly, and the error of movement time is little；
What 3, dividing plate avoided ptc heater exit positive and negative electrode mutually touches the sparking short circuit caused, simultaneously can be right
Ptc heater has assembled position-limiting action；
4, the screw hole of screwing does not results in stripped thread when can ensure that fixed screw, chip comes off caused short circuit,
The problems such as defective insulation；
5, the chamfering of upper cover surrounding does not haves gap, sealing after upper complete screw after having played screw with housing, can discharge water
Antitheft.
Present invention life-span length, lightweight, stable and reliable operation, protector and the stable action time of fuse-link, water proofing property
Good, the assembling with air-conditioner host fits together perfectly.

Detailed description of the invention
The present invention is described in detail in detail with reference to the accompanying drawings.
With reference to Fig. 1, housing 11 has upper cover 2, has above covered screw hole 1, dividing plate has and matches with screw hole 1
Screw hole 27.Upper cover 2 can be connected as a single entity with housing 11 by screw 1, screw hole one 3,27.Detachable upper cover unloads, it is simple to return
Work utilizes.
With reference to Fig. 1,4,5, upper cover and housing joint portion surrounding have chamfering 4, and upper cover is backed with the projection one withstanding fuse-link
13, the projection 2 14 of thermal protector is withstood.The chamfering of upper cover surrounding, after having played screw, makes not have between upper cover and housing seam
Gap, sealing again after upper complete screw, also discharge water theftproof performance.Protruding 1 withstand fuse-link does not rocks, and protruding 2 14 withstand heat
Protector does not rocks,
With reference to Fig. 1,2,3, by the buckle of fixing thermal protector position on housing, in housing, there is determining by thermal protector root
Position post 5, can fix thermal protector, make being heated evenly of protector, stable action time.Determining of fixing fuse-link is had in housing
Position tongue 6, specify that the rigging position of fuse-link, and fuse-link fits together perfectly with tongue, is heated evenly, the error of movement time
Little.The dividing plate 8 of isolation ptc heater exit both positive and negative polarity is had, it is to avoid ptc heater exit both positive and negative polarity mutual in housing
The sparking short circuit that touching is caused, can assemble position-limiting action to ptc heater simultaneously.
Housing Base is fixed on air-conditioner host installing hole 9, cylinder locating dowel 10, it is ensured that ptc heater is at air-conditioning
Fixing intensity in main frame.
Item 12 is stretched out in having of housing bottom, stretches out item and can not only fix ptc heater and can save material.
Using the present invention, ptc heater inserts in housing, and top is stuck with buckle.Thermal protector root is leaned against location
On post, fuse-link is fixed on tongue, and the both positive and negative polarity of ptc heater exit is separated by dividing plate, then is incited somebody to action by screw, screw hole
Upper cover is connected as a single entity with housing.
Present invention life-span length, lightweight, stable and reliable operation, protector and the stable action time of fuse-link, water proofing property
Good, the assembling with air-conditioner host fits together perfectly.
