The air outlets are arranged around the connecting sheet 531 at intervals; the air outlet 533 extends from the middle part to the edge; when the filling block 211 moves downwards to extrude the cold air, the adjusting plate 135 is embedded and closed in the gap 134, the elastic membrane 53 expands, the plurality of air outlets 533 are opened to release the cold air to the periphery to impact on the component 11, and the released cold air can just impact on the surfaces of the component and the electrical appliance part to dissipate heat; when the filling block 211 retracts, the adjusting plate 135 is separated from the gap 134, the elastic membrane 53 is contracted and attached to the stable frame 51, and the air outlet 533 is closed; cold air enters the air inlet chamber and the fixed cavity through the gap; the exhaust holes are sealed through the elastic membrane, the filling block can prevent the higher temperature gas in the cabinet body from flowing into the fixed cavity in the upward movement process, and the influence on the heat dissipation effect is avoided.

The bottom of the fixed cavity 13 is provided with an exhaust hole 132; an electric appliance part 17 is arranged at the bottom of the cabinet body 1; the electric appliance part 17 is arranged at a distance from the fixed cavity 13; the electrical component 17 is arranged on the stabilizing structure 6; the stabilizing structure 6 comprises a support bar 61; the plurality of support rods 61 are arranged and fixed at the bottom of the cabinet body 1 in an array manner; sliding plates 62 are fixedly supported on the plurality of supporting rods 61; the electrical component 17 is correspondingly arranged on the sliding plate 62; the electric appliance components can be independently placed on the sliding plate by opening the cabinet door at the bottom of the cabinet body, so that the electric appliance components can be conveniently taken and placed;

the sliding plate 62 is provided with a tabling hole 621 corresponding to the supporting rod 61; the bottom of the electrical component 17 is fixedly provided with an embedded column 171; the insertion posts 171 are inserted into the insertion holes 621; a lifting rod 622 is arranged in the embedding hole 621; a bearing block 623 is fixedly arranged on the lifting rod 622; the bearing block 623 is correspondingly supported on the embedding column 171 and drives the electrical component 17 to move up and down to enter and exit the embedding hole 621. And when electrical components slide in place, through embedding post embedding gomphosis downthehole, just can carry out spacingly to electrical components, guarantee electrical components's stability to embedding post and carrier block are magnetic structure, can be better spacing.

The first step is as follows: the outside air is firstly introduced into the ventilation chamber 161, cooled by the cooling area 32 and then introduced into the air inlet chamber 15 and the fixed chamber 13; then the filling block 211 moves downwards to press the cold air in the fixing cavity 13 to impact the assembly 11 and the surface of the electrical component 17 through the air exhaust hole 132 for heat dissipation; and normal operation of the assembly and the electrical parts is guaranteed.

The second step is that: when the air outlet hole 132 is exhausted, the adjusting plate 135 is closed in the air inlet chamber 15; when the air inlet chamber 15 is filled with air, the elastic membrane 53 is closed on the exhaust hole 132; air inlet and exhaust in order like this can guarantee that air conditioning gets into fixed intracavity, avoids the higher gaseous reverse flow of temperature to fixed intracavity, influences radiating effect.

The third step: the electrical component 17 can be taken and placed through a cabinet door at the bottom of the cabinet body 1; the electrical component 17 slides on the slide plate 62 by the action of external force and is inserted into the fitting hole 621; when the embedded column 171 is supported by the bearing block 623, it can slide out of the electrical component 17 by an external force.

In view of the foregoing disclosure, it will be seen that the present invention is not limited by the particular embodiments disclosed, but is capable of modifications and variations within the spirit and scope of the invention as defined by the appended claims.
