Abstract
Circular heat exchangers have been used to increase the efficiency of engines by absorbing heat from the exhaust gases and transferring a portion of the exhaust heat to the intake air. The present heat exchanger is built to better seal the cooler recipient fluid from the heated recipient fluid and the donor fluid within the operation of the heat exchanger. The circular heat exchanger is also easily removable from the engine should repair or servicing be required. The manifold is interwoven between the inlet ports and the outlet ports and sealingly separates the cool recipient fluid from the heated recipient fluid. The tongue and groove compensates for the expansion and contraction of the core due to the thermal variations imputed by exhaust from the engine and compensate for such thermal variations.
