19858 results about "Heat conducting" patented technology

Heat conduction. Heat conduction, or thermal conduction, is the spontaneous transfer of thermal energy through matter, from a region at higher temperature to a region at lower temperature. It thus acts to equalize temperature differences. It is also described as heat energy transferred from one material to another by direct contact.

Heat Dissipating LED Signal Lamp Source Structure

A heat dissipating LED signal lamp emitting structure includes an isothermal board, a light emitting unit on the isothermal board, a heat conducting cylinder connected to the bottom of the isothermal board, a heat dissipating body around the periphery of the heat conducting cylinder and comprised of heat sinks, a circular cover body above the isothermal board for covering the isothermal board, a reflecting groove at the center of the cover body for passing through the light emitting unit, and a transparent lid on the cover body for covering the light emitting unit. With the heat dissipating effect of the heat dissipating body, the operating heat produced by the light emitting unit can be dissipated to the outside. The invention not only uses a single light emitting unit as a signal lamp emitting source, but also enhances the light emitting efficiency and the life expectancy of the light emitting unit.

High efficiency heat removal system for rack mounted computer equipment

An efficient method of heat removal from rack mounted computer equipment, network gear and other electronic equipment, consisting of solid heat conducting components in direct contact with the heat generating sources. In particular, this invention is primarily focused on the ability to efficiently and effectively cool computer equipment in standard computer rack cabinets.This invention utilizes a design that retains the general existing form factor of the rack mounted computer equipment, but uses direct contact heat transfer to a metal heat transfer conduit (Copper, Aluminum or other metal or efficient heat conducting material) contained within the computer equipment chassis. Furthermore, it is thermally coupled to an external rack mounted solid-to-fluid heat exchanger as an efficient method of heat transfer and removal. This is much more efficient than air as heat transfer medium which it the common method of heat removal from existing standardized rack mounted computer equipment.This invention covers the design of the heat transfer components within the chassis of rack mounted computer server and the heat transfer system components external to the server within rack enclosure, as well as the external cooling system components necessary to connect to existing fluid based heat transfer and removal systems and processes.
