Assembly for liquid cooling electronics by direct submersion into circulated engine coolant.

摘要

An assembly (10) for liquid cooling electronics by direct submersion into circulated engine coolant that includes an epoxy material (48) dispensed around leads (42,44) of electronics devices (combination of 34, 36, 38) in a manner effective to mechanically secure the electronics devices to the assembly (10) and prevent engine coolant leakage around the leads, and a Parylene™ coating layer (50) deposited in a manner effective to protect the electronic device (34) from electrically conductive engine coolant such as ethylene glycol. Such an assembly (10) is useful in hybrid electric vehicles that have engine coolant available from the vehicle's internal combustion engine.
