The edge of described ceramic gasket and the inward flange of described limitting casing fit tightly.
On the installed surface of described radiator, have locating hole, described limiting bracket has location leg, and described location leg is plugged in described locating hole.
Described limitting casing has at least one and its frame inner region is partitioned into the medial support bar of a plurality of subregions.
The thickness of described limitting casing is greater than the thickness of described ceramic gasket.
The utility model has also proposed a kind of air-conditioner, comprises controller of air conditioner, and described air-conditioner controller has the assembly structure of above-mentioned air-conditioner controller power device.
Compared with prior art, the utlity model has following advantage and good effect:
1, by limiting bracket, to ceramic gasket, carry out spacing, make ceramic gasket can not move along with the movement of the control panel of air-conditioner controller, avoid the locating hole dislocation on radiator and ceramic gasket, be convenient to screw fastening, improve assembling and production efficiency, improved the reliability of product simultaneously;
2, when power device is while being a plurality of, limitting casing inner region is partitioned into the subregion of respective numbers by medial support bar correspondence, thereby can reduce the contact area of ceramic gasket and radiator, greatly reduce the impact of radiator flatness on ceramic gasket, reduced the possibility that ceramic gasket crushes due to radiator out-of-flatness;
3, simple in structure, easy for installation, cost is low.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in more detail.
With reference to Fig. 3 to Fig. 7, the assembly structure of the present embodiment air-conditioner controller power device, comprise radiator 1, power device 2 and the ceramic gasket 3 between radiator 1 and power device 2, power device 2 passes through pin welded and installed on control panel 4, be power device 2, ceramic gasket and limiting bracket 5 between radiator 1 and control panel 4, after above-mentioned each parts assembling as shown in Figure 5.As shown in Fig. 3, Fig. 4 and Fig. 6, radiator 1 comprises installed surface 1.1 and has the radiating surface 1.2 of radiating fin, ceramic gasket 3 fits with the installed surface 1.1 of radiator 1, radiator 1, power device 2 and ceramic gasket 3 threes are fixed as one by screw fastening, on the installed surface 1.1 of radiator 1, be installed with the limiting bracket 5 of insulation, limiting bracket 5 has limitting casing 5.1, and ceramic gasket 3 is positioned at limitting casing 5.1.
The assembling process of the assembly structure of the present embodiment air-conditioner controller power device is: limiting bracket 5 is installed on the installed surface 1.1 of radiator 1, then ceramic gasket 3 is put in the limitting casing 5.1 of limiting bracket 5, by limitting casing 5.1, undertaken spacing, the screw hole of ceramic gasket 3 is the screw hole of centering radiator 1 just in time, how the control panel 4 no matter being placed on ceramic gasket 3 moves, spacing due to limitting casing 5.1, ceramic gasket 3 can not move dislocation, power device on control panel 42 is spread after silicone grease, be assembled on electric fitting box, power device 2 aligns ceramic gasket 3, urgent in power device 2 with screw, ceramic gasket 3 is fixed on radiator 1, assembled.
Why limiting bracket 5 is insulation material, because ceramic gasket 3 will contact with the power device 2 on control panel 4, limiting bracket 5 also can inevitably contact with power device 2, and limiting bracket 5 is installed on radiator 1, because power device 2 is nonisulated material, for preventing conduction, limiting bracket 5 is made by insulating materials such as plastics or quartz or high strength glass materials.
For further strengthening the position-limiting action of 5 pairs of ceramic gaskets 3 of limiting bracket, the inward flange of the edge of ceramic gasket 3 and limitting casing 5.1 fits tightly.
