Abstract
Apparatus (,) controlling the temperature within a sealed enclosure (,) housing electronic components (E) whose operation produces heat, and whose operation should occur within a desired temperature range. A heat sink (,) extending through an enclosure endwall (,) conducts heat from within the enclosure to the atmosphere. Other heat sinks (,) mounted within the enclosure are in a thermal transfer relationship with the components for heat generated by the components to be drawn to the heat sinks away from the components. A heat pipe (,) extending between the respective heat sinks conducts the heat to the first said heat sink for heat to be expelled from inside the enclosure to the atmosphere. A heater (,) within the enclosure generates heat to heat the components, and a thermostat (,) senses when the temperature within the enclosure falls below a predetermined temperature to energize the heater. Heater is sized to cause a “dry out”, condition in the heat pipe when the thermostat energizes the heater. As a result, the temperature in the enclosure is maintained within the desired range by appropriately removing heat, from or generating heat within, the enclosure and controlling the heat transfer path.
