ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to an improved power supply device for computer system, wherein each terminal edge of computer case is bent inwardly to form a fix-to-joint portion for fixedly jointing with a computer system in order to expand space available in the computer system.
In consideration of product circulation, design convenience, and component availability, most electronic and mechanical products are made in unified specifications.
Take a PS/2 type back-up power supply device for example, a conventional power supply device shown in
FIG. 1
has one set of power supply units disposed in a computer case, wherein the inner wall of the case is cut and bent to form a plurality of compartments; a power-input port is arranged in one open end of the case for connecting with the power supply units; a power-control panel is sealed in the other closed end of the case; each terminal edge of the open end of the case is extended outwardly and bent to form a fix-to-joint strip for connecting to the computer system with fixing pieces to thereby build a back-up power supply device. However, such a build is imperfect in the following points:
1. The case of PS/2 type becomes larger owing to the outwardly bent fix-to-joint strip, which is liable to be deformed by impact and affect disposing space of relative components.
2. The heat dissipation efficiency is degraded in the closed case that may shorten lifetime of the power-control panel and the power supply units, and besides, the cut and bent case does not provide effective guideways for inserting the power supply units in the case properly, and the power-control panel is not protected against touch by people's hands or foreign goods.
3. As only one power-input port is available, therefore, in case of power failure or breakdown, the back-up type power supply device can not operate normally.
SUMMARY OF THE INVENTION
The primary object of this invention is to bend each terminal edge of an open end of a case inwardly to form a fix-to-joint portion respectively and form a plurality of joint portions in the fix-to-joint portion so that a power supply device can be fixed in a computer system with fixing pieces and the available space in the computer system can be expanded.
Another object of this invention is to provide one set of heat dissipation fans and a power-input port to each power supply unit so that an impaired component can be replaced independently.
A further object of this invention is to provide one set of correspondent guideways and slide tracks on the case and the power supply unit respectively for guiding the latter to slide in the former smoothly, and a power-control panel disposed between an air frame with vent openings and a shield board with heat dissipation holes that cooperate with a plurality of heat dissipation holes in the power supply units to thereby lower temperature in the case and protect the power-control panel against touch of people's hands or foreign goods.
