  • Patent number: 6394076
    Abstract: An engine charge air cooler system including a charge air compressing system, a refrigerant cycling system, and a charge air cooling apparatus for transferring heat from the compressed charge air of the charge air compressing system to the refrigerant fluid of the refrigerant cycling system. The charge air cooling apparatus comprises a housing with a charge air passage for charge air moving through the housing. A plurality of fins are positioned in the charge air passage. A fluid tube is provided in the housing and passes through each of the fins in a plurality of locations. Preferably, the refrigerant compressor of the system is adapted to also compress a separate flow of refrigerant fluid for an air conditioning system of the vehicle in addition to the refrigerant fluid of the system of the invention. A heating element may be provided in the interior of the housing, and may be selectively heatable for preventing accumulated moisture from freezing in the interior of the housing in sub-freezing temperatures.
