Abstract: An intercooler for a turbocharged internal combustion engine having a housing with opposite V-shaped side walls and a heat exchanger core inside the housing with straight pipes carrying heat conducting fins. The pipes pass a coolant lengthwise through the housing. Triangular spaces between the heat exchanger core and the respective V-shaped side walls of the housing cause a substantial equalization of the air flow across all of the fins, producing a more efficient heat transfer from the air to the coolant in the pipes.
