Patent ID: 7017656

Claim:
A heat exchanger comprising: a. a core having a heat exchange portion; b. a fluid-permeable metal tube including a motion limiter attached thereto and extending radially therefrom in a channel wherein the motion limiter limits upward or downward axial motion of the tube, wherein clearance exists in the channel to allow substantially unrestricted sideways movement of the tube due to thermal expansion of the tube wherein at least a portion of the tube extends into the core and is capable of being in contact with the core to transfer loads between the tube and the core, to provide support to the core and to increase the stiffness of the core, and wherein the tube is positioned at least adjacent to the heat exchange portion of the core; c. a load bearing member positioned adjacent the core; and d. a first mount positioned between the tube and the load bearing member, so that the load bearing member can receive loads from the tube via the motion limiter.
