Abstract

A heat exchanger for cooling a liquid has an inlet and an outlet for a liquid to be cooled. A bypass is provided that bypasses the heat exchanger. A valve controls flow of liquid into the heat exchanger or into the bypass. The valve has a valve seat, a valve cone, and at least one spring made of a shape memory material. The at least one spring counteracts a liquid pressure existing in the inlet.
