Abstract
The utility model relates to a switch power supply housing which can solve the contradiction between the heat radiation and the appearance under the mute and fan-less condition. The switch power supply housing is composed of a metal pedestal and a top cover. The lower part of the metal pedestal is provided with a U-shaped groove which places a PCB. An inner wall of the pedestal is provided with a metal heat radiation board which forms a through groove with the inner wall of the pedestal. The PCB slides into the pedestal along the U-shaped groove. A power device adheres to the metal heat radiation board. A high strength elastic clamp fixes the power device, and the heat is transmitted to the switch power supply housing via the metal heat radiation board.
Description
[technical field]
The utility model relates to a kind of Switching Power Supply shell.
[background technology]
At present, existing Switching Power Supply shell is mainly as containment vessel, the fixed, internal module, and function ratio is more single, and the heat that the internal power device produces rests near device surface or the small heat-dissipating sheet, can not well give out in the external environment condition.
[utility model content]
The utility model has overcome the deficiency of above-mentioned technology, the Switching Power Supply shell that provides a kind of inside to be shaped on heating panel.
For realizing above-mentioned purpose, the utility model has adopted following technical proposal:
The Switching Power Supply shell comprises metab 1 and top cover 2, and said metab is shaped on U type groove 4 respectively on 1 both sides; At least be provided with on metab 1 inwall one be used for fixing power device metallic heat radiating plate 5; So design, pcb board directly slips in the U type groove 4, and power device is near metallic heat radiating plate 5.
Described metallic heat radiating plate 5 comprises heatsink transverse plate 51 and vertical heating panel 52 down; Following heatsink transverse plate 51 is fixed on the base inner wall; Vertical heating panel 52 is connected heatsink transverse plate 51 ends; Surround one between described heatsink transverse plate 51 down, vertical heating panel 52 and metab 1 inwall and be convenient to the groove 54 that high strength elastic folder 7 injects, utilize the high strength elastic folder to be fixed on power device on the metallic heat radiating plate 5, power device is closely contacted with the Switching Power Supply shell; Thermal resistance is little, need not to design in addition fin.
Described metallic heat radiating plate 5 comprises heatsink transverse plate 51, vertical heating panel 52 and last heatsink transverse plate 53 down; Following heatsink transverse plate 51 is separately fixed on the base inner wall with last heatsink transverse plate; Vertical heating panel 52 is connected down between heatsink transverse plate 51 and last heatsink transverse plate 53 ends; Described following heatsink transverse plate 51, last heatsink transverse plate 53, vertical heating panel 52 surround groove 55 with metab 1 inwall; On vertical heating panel 52, have screw hole 9, be fixed on power device on the metallic heat radiating plate 5 with screw, its heat-sinking capability is still fine.
Described metab 1 is integrated with described metallic heat radiating plate 5.
The design is primarily aimed in power device such as rectifier bridge GBU encapsulation, the heat radiation of metal-oxide-semiconductor and bipolar transistor and Schottky tube TO-220 and TO-3P encapsulation etc.The element of this type encapsulation all has pin, and is usually used in high voltage end, and when therefore designing, discharge air-gap or creepage distance between power device pin pin and the metal shell are greater than 2.5mm.
As optimization, the metallic heat radiating plate side is stained with soft silica gel conducting strip, and high resilience can be filled the gap naturally, and heat-conducting effect is better.
As optimization, Switching Power Supply outer cover metal base outer surface is shaped on radiation tooth, so design, and the heat that is produced when making power work is distributed more easily.
The beneficial effect of the utility model is:
1, whole heat conduction and heat radiation is effective, heat well from the conducted inside of outer casing of power supply to external environment condition, guarantee the operate as normal of circuit.
2, whole design outline is attractive in appearance, installs simple and easyly, is easy to realize safety, need not design independently small heat-dissipating sheet.
