Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

(embodiment 1)

See Fig. 1 to Fig. 3, the shell of the present embodiment participates in the Switching Power Supply of heat radiation, and it is mainly made up of shell 1, circuit arrangement and heat radiation fixation kit 3.

Shell 1 is mainly made up of upper cover 11 and base 12. Upper cover 11 is provided with one group of heat radiation slotted eye 11-1. Base 12 is made up of base plate 12-1 and 2 side plate 12-2 one, and 2 side plate 12-2 are each respectively in the upper end, the left and right sides of base plate 12-1 arranges 1; On base plate 12-1, be also provided with heat radiation slotted eye. While installing, upper cover 11 is fastened on the upper end of base 12 and is screwed connection. The material of shell 1 is the aluminium easily dispelling the heat.

Circuit arrangement comprises 2 output rectifying tubes, 2 components and parts such as grade. The circuit arrangement of Switching Power Supply is existing mature technology, does not describe in detail. One of main power heater members that output rectifying tube 2 is Switching Power Supply.

Heat radiation fixation kit 3 is mainly made up of radiating connection plate 31, heat radiation fixture 32, insulating heat-conductive pad 33 and hold-down screw 34.

Radiating connection plate 31 is rectangular plate body part, preferably adopts aluminium in material the present embodiment of radiating connection plate 31; Radiating connection plate 31 is provided with the screw hole that connects use.

Referring to Fig. 4 and Fig. 5, heat radiation fixture 32 is made up of pressing plate 32-1, upper plate 32-2, upper ear plate 32-3, lower plate 32-4 and lower ear plate 32-5 one. Pressing plate 32-1 is provided with the screw hole 32-1-1 that connects use; On the lower surface of the upper surface of upper plate 32-2 and lower plate 32-4, be respectively equipped with fine and closely woven lug, nib; Heat radiation fixture 32 adopts the object of this kind of structural design, considers on the one hand installing space finiteness problem, considers to increase on the other hand the area of dissipation of heat radiation fixture 32.

When installation, 1 side plate 12-2 that radiating connection plate 31 is close to the base 12 of shell 1 goes up and is screwed connection; Heat radiation fixture 32 is pressed in 2 output rectifying tubes 2 on radiating connection plate 31 through insulation heat conductive pad 33 by its pressing plate 32-1, hold-down screw 34 matches and is fixedly connected with the screw hole 32-1-1 on the pressing plate 32-1 of heat radiation fixture 32 after through the screw hole on radiating connection plate 31, insulating heat-conductive pad 33, thereby just 2 output rectifying tubes 2 are clamped in radiating connection plate 31 and dispel the heat between fixture 32.
