Abstract
To provide a heat exchanger that can control temperatures of fluids to be heat-exchanged. A heat exchangerincludes a honeycomb structure, a second fluid flow through portionlocated at an outer periphery side of the honeycomb structureserving as a flow passage for a second fluid, and a third fluid flow through portionlocated at an outer periphery side of the second fluid flow through portionserving as a flow passage for a third fluid. Cellsof the honeycomb structureserve as a first fluid flow through portionthrough which the first fluid passes. With the heat exchanger, the first fluid, the second fluid, and the third fluid can be heat-exchanged without being mixed with one another. Constituting the fluid flow passage with three flow passages allows controlling temperatures of two fluids to be heat-exchanged by the residual fluid.
