Abstract:
A heat exchanger which performs heat exchange between a high temperature fluid and a low temperature fluid, comprising:a heat exchanging portion comprising a first fluid passage allowing flow of a first low temperature fluid, a second fluid passage partitioned from the first fluid passage and allowing flow of a second low temperature fluid, and a high temperature fluid passage allowing flow of the high temperature fluid, the high temperature fluid passage being in contact with the first fluid passage to heat the first low temperature fluid and being in contact with the second fluid passage to heat the second low temperature fluid; a first supply mechanism which supplies the first low temperature fluid to the first fluid passage; and a second supply mechanism which supplies the second low temperature fluid to the second fluid passage, wherein a flow direction of the first fluid passage and a flow direction of the second fluid passage are each set to intersect a flow direction of the high temperature fluid passage, and the second fluid passage is disposed upstream of the first fluid passage with respect to the flow direction of the high temperature fluid.
