Enclosure for electronic equipment generating heat losses - contains cooling ducts acting as heat exchanger and filled with evaporable medium

摘要

The application is to electronic equipment employing power circuits which produce heat losses and therefore require cooling. The housing (1) comprises a lid with a vertical section (3) and a horizontal section (2). Embedded in these sections are continuous, closed heat pipes (4) forming a spaced out cooling system. The main heat generating elements (6), for example power transistors, are mounted on a strip (5) at the base of the vertical section (3). The heat pipes are filled with a liquid which vaporises by the heat from the circuit elements (6) and condenses again in the horizontal part of the cover. In this way the thermal losses are dissipated in a system acting as a heat exchanger. The space requirements are less than for a direct air cooled system employing convection.
