Abstract
A heat exchanger, has: a heat exchanger core having an inlet, an outlet, at least one first conduit connecting the inlet to the outlet, and at least one second conduit in heat exchange relationship with the at least one first conduit; a bypass conduit connecting the inlet to the outlet while bypassing the at least one first conduit; and a valve in communication with the bypass conduit and having: a valve member movable between a closed position in which fluid communication through the valve and via the bypass conduit is blocked and an open position in which fluid communication through the bypass conduit and through the valve is permitted, the valve member defining an auxiliary passage, and a thermal fuse overlapping the auxiliary passage and blocking fluid communication through the valve member via the auxiliary passage, the thermal fuse having a melting temperature above a predetermined temperature of the fluid.
