Prism Enterprise supplies Heat Sinks for Enhancing Heat Dissipation. Prism Enterprise is an ISO 9001:2000 accredited company. Prism Enterprise is the manufacturer of Electrical and Engineering products like heat sinks, extruded heat sinks etc. The Heat Sinks enhance heat dissipation from a hot surface, such as a device generating heat to a cooler ambient, usually air. The primary purpose of a heat sink is to maintain the device temperature below the maximum allowable temperature specified by the device manufactures. The Heat Sinks for Enhancing Heat Dissipation have fins and/or ridges which are used to increase the surface area. The extra surface area allows more metal to come into contact with the air, which allows the heat to be dissipated more quickly. A heat sink is used when environmental/design controls fail to bring the junction temperature within reasonable limits. Higher thermal energy transfer efficiency of heat sinks is due to the low thermal resistance between heat sink and air.
