Abrégé

The invention relates to a heat exchanger (10), particularly an oil cooler for an internal combustion engine, comprising: a main inlet channel, a main outlet channel, a main outlet channel for a coolant circuit, and; a main inlet channel (16) and a main outlet channel (18) for a circuit for a medium to be cooled. The respective main inlet channel (16) is connected to the associated main outlet channel (18) via flow channels (22, 24), which have inflows and outflows and are provided for the actual heat exchange. The flow channels of one circuit are passed through by the inflows and outflows of the other circuit. The invention is characterized in that, in the area of the inflows (26) of at least one circuit for bypassing the flow channels (22), which are situated downstream from these inflows (26), a bypass channel (36) is provided with a pressure relief valve (46), and the bypass channel (36) leads into the associated outflows (32) or into the associated main outlet channel (18).
