UNINTERRUPTIBLE POWER SUPPLY HAVING CLAMP OF HEAT SPREADER FUNCTION

摘要

An uninterruptible power supply having a clamp of a heat dissipating function is provided to prevent a damage of a semiconductor product caused by thermal deterioration of a power converting device or damage of the clamp. An uninterruptible power supply having a clamp of a heat dissipating function includes a power converting device(102) used in a rectifying unit(100) of the uninterruptible power supply. A bus bar(104) is connected to the power converting device(102), and is placed on a top of the power converting device(102). An upper heat sink(106) is placed on the bus bar(104) to be contacted to the bus bar(104). A lower heat sink(108) is placed under the power converting device(102). A clamp(110,112) tightens the upper heat sink(106) and the lower heat sink(108) to fix the bus bar(104) and a power supply device. The clamp(110,112) includes a heat dissipation device(120) dissipating heat generated from the power supply device.
