<p>There is disclosed herein a heat exchanger construction of the finned fluid conduit type which includes an integral pressure actuated by-pass fluid assembly adapted to enable fluid being circulated through the heat exchanger to by-pass the core portion thereof when header pressure exceeds a predetermined pressure. The heat exchanger of the present invention comprises an inlet header, outlet header, and interconnecting heat exchanger core assembly and a continuous by-pass fluid conduit member extending therebetween in which is disposed a pressure responsive valve adapted to control fluid flow between the inlet and outlet headers. The continuous fluid by-pass conduit is designed to have a pressure relief valve removably positioned internally thereof and preferably will have one end extending completely through one of the headers which end may be provided with a suitable removable closure member to facilitate installation and/or replacement of the pressure relief valve.</p> |
