1) screw fixation method, easily loosening in the environment for use of vibration, device is comparatively heavy;
2) reinforcement is connected and fixed mode, and installation dimension control difficulty is installed difficulty;
3) housing fixed form, material and die cost are high, and heat resistance is bad.
Utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of air conditioning for automobiles ptc heater, is intended to solve existing ptc heater the technical problem inconvenient, cost is higher is installed.
The utility model is to realize like this, a kind of air conditioning for automobiles ptc heater, comprise bottom base and be arranged on the heating core body between described upper bottom base, described heating core body one end is provided with T-shaped fin, described bottom base is provided with the installation foot of hollow, and described T-shaped fin is through described installation foot, and described heater also comprises snap close, described snap close front end offers flat recess, and described T-shaped fin is arranged in described flat recess.
Further, on described dress pin, also cover has silicon rubber cup.
Further, described snap close outer surface is also provided with projection, also offers the opening matching with described projection on described installation foot.
Further, the described heating core body other end is provided with convex, and described top base correspondence position is provided with groove, and described heating core body plug button is bonded to described top base.
Further, described snap close tail end also offers hexagonal hole.
The beneficial effects of the utility model are: in the utility model, heating core body one end is set to T-shaped fin structure, general aluminium material, in the time that bottom base is installed, the flat recess of snap close is inserted into described T-shaped fin, then rotates described snap close certain angle, T-shaped fin generation deformation, can tightly block bottom base, can easily heating core body and bottom base be fixed together.The utility model assembling is simple and convenient, materials are few, cost-saving.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
For technical scheme described in the utility model is described, describe below by specific embodiment.
Fig. 1 shows the blast structure of the air conditioning for automobiles ptc heater that the utility model embodiment provides, and only shows for convenience of explanation the part relevant to the utility model embodiment.
As shown in Figure 1, the air conditioning for automobiles ptc heater that the present embodiment provides comprises bottom base 1,3, and be arranged on the heating core body 2 between described upper bottom base, as shown in Figure 2, described heating core body one end is provided with T-shaped fin, described bottom base 3 is provided with the installation foot 6 of hollow, described T-shaped fin is through described installation foot, and described heater also comprises snap close 4, as shown in Figure 3, described snap close 4 front ends offer flat recess, and described T-shaped fin is arranged in described flat recess.
In the present embodiment, described T-shaped fin is aluminium material, in the time that bottom base 3 is installed, first heating core body is inserted in bottom base with one end of T-shaped fin, now T-shaped fin is through installation foot 6, then snap close 4 is inserted in described T-shaped fin, twists described snap close 4 certain angles, such as 90 °, now T-shaped fin generation deformation, the T-shaped fin of distortion can firmly block bottom base, quickly and easily heating core body and bottom base is installed as to one, and structure is more firm.Preferably, after snap close installs, on described installation foot 6, silicon rubber cup 5 is installed, described silicon rubber cup 5 does not contact with the external world for the protection of snap close, prevents that snap close is loosening, opens in addition and can play collision prevention function.
For the convenient snap close that rotates, as a kind of preferred implementation, described snap close tail end also offers hexagonal hole, and six square spanner instruments are inserted after described hexagonal hole, can rotate easily snap close to expecting angle.In addition, loosening, further preferred in order to prevent snap close, described snap close 4 outer surfaces are also provided with projection 41, on described installation foot 6, also offer the opening 61 matching with described projection 41, twist snap close described projection 41 is just in time stuck in described opening 61, prevent that snap close is loosening.
For installing pedestal 1, as the concrete mounting means of one, described heating core body 2 plug buttons are bonded to described top base 1, concrete, with reference to Fig. 4, one end that described heating core body differs from T-shaped fin is provided with convex 21, described top base 1 correspondence position is provided with groove 11, heating core body is inserted into after top base, and described convex 21 is just in time stuck in described groove, and heating core body and top base are fixed as one.So far completed ptc heater installation, Fig. 5 is the schematic diagram after whole ptc heater installation.
To sum up, originally be that utility model embodiment provides a kind of new ptc heater mounting means, by T-shaped fin and snap close are set, T-shaped fin reversed to certain angle and make its distortion, the T-shaped fin that produces deformation can well block bottom base, and heating core body and bottom base are firmly fixed as one.This mounting means is simple, and materials are few, and sound construction can be widely used in air conditioning for automobiles ptc heater industry.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
