A heat exchange device for vehicles (in particular an oil cooler arrangement in which the oil is cooled by water drawn from the vehicle engine cooling system) includes a first oil cooling heat exchanger 11, and an auxiliary oil cooling heat exchanger 15 connected in parallel thereto. A portion of the oil supplied at 17 to the exchanger 11 can be diverted via a by-pass passage 16 selectively closeable by means not shown, through a connection 18 into the auxiliary heat exchanger 15. When the by-pass passage 16 is open the flow of oil is divided, substantially equally, between the two heat exchangers 11, 15. The arrangement can include an oil filter 38 and the inlet 41 thereto from the heat exchanger 15 is closed when the by-pass 16 is closed. <IMAGE> |
