[Problem] To provide a high-efficiency heat exchanger which can be applied to a high-purity fluid to be subjected to heat exchange. [Solution] A heat exchanger is provided with a flow passage through which fluid to be subjected to heat exchange flows and a heat transmission structure which is in contact with the fluid to be subjected to heat exchange flowing through the flow passage. The heat exchanger performs heat exchange by heat transfer effected through the contact surface where the fluid to be subjected to heat exchange and the heat transmission structure are in contact with each other. The heat exchanger is characterized in that: (1) the surface of the heat transmission structure, which is in contact with the fluid to be subjected to heat exchange, consists of a material stable against the fluid to be subjected to heat exchange; (2) the heat transmission structure is provided with a heat conduction body, and the heat conduction body consists of a material having a good coefficient of heat conductivity; and (3) the heat conduction body is mounted near the contact surface, which is in contact with the fluid to be subjected to heat exchange, at a position not in contact with the fluid. In the heat exchanger, the efficiency of heat conduction through the surface where the heat transmission structure and the fluid to be subjected to heat exchange are in contact with each other is high. |
