摘要:
An apparatus comprises a thermal block (116) coupled to an electronic device (352), a thermal strap (102) coupled to the thermal block (116), and retention hardware (230) coupled to the thermal strap (102) and configured to retain the thermal block (116) within the thermal strap (102) when the apparatus is exposed to at least one variable environmental condition.
摘要:
An electronics chassis, 12, for containing and supporting electronic components having different operating temperatures includes a plurality of thermally conductive walls forming an enclosure. There is a first heat dissipator, 30, in at least one of the walls having a external heat dissipator and a second heat dissipator, 32, in at least one of the walls having a external heat dissipator. There is a thermal isolator, 34, positioned in at least one of the walls to provide thermal isolation between the heat dissipators, and the thermal isolator includes a thermally insulating material.
摘要:
A motor controller for use in an environment at a high maximum environmental temperature comprises an insulated chassis, a high-temperature capable electronic component, a low-temperature capable electronic component, and a heat pump. The high-temperature capable electronic component is rated for a temperature higher than the environmental temperature, whereas the low-temperature capable electronic component is rated for a temperature lower than the maximum environmental temperature. The insulated chassis has a finned surface to which the high-temperature capable electronic component is mounted, either directly or via thermally conductive posts. The low-temperature capable electronic component is attached to or integrated into a printed wiring board supported inside the insulated chassis by the thermally conductive posts. The heat pump is configured to draw heat from the low-temperature capable electronic component through the thermally conductive posts and a thermal spreader abutting the heat pump, and to expel heat into the finned surface of the insulating chassis.
