Abstract (en)
[origin: EP2998687A1] Provided is a heat exchanger having improved heat transfer performance. A heat exchanger (100) according to the present invention includes a heat transfer unit (102) configured to perform heat exchange by contact with gas (112), and a contact surface (102a) of the heat transfer unit (102) to be in contact with the gas (112) is provided with a fine structure body (102b) which has a height of 10 µm or less and a surface area of 10 times or more of a smooth surface. The gas (112) desirably has a Reynolds number of 30,000 or more, and the fine structure body (102b) is desirably formed of the same material as that of a base material forming the contact surface (102a). Moreover, the fine structure body (102b) desirably has heat conductivity equal to or larger than the base material forming the contact surface (102a).
