(1) Partition-type heat exchanger. Two fluids at different temperatures are allowed to flow in a space separated by a wall, and heat exchange between them occurs through heat conduction through the wall and convection of the fluids at the wall surface. (2) Regenerative heat exchanger. With the help of a heat storage material made of a solid, heat is transferred from a high-temperature fluid to a low-temperature fluid. The heat storage material comes into contact with the high-temperature fluid for a certain period of time, absorbing and storing a certain amount of heat, and then comes into contact with the low-temperature fluid for a certain period of time, releasing that heat to the low-temperature fluid. (3) Fluid-connected indirect heat exchanger. A heat exchanger that connects two surface-type heat exchangers through a heat carrier circulating within them. (4) Direct contact heat exchanger. It is a device in which two fluids come into direct contact for heat exchange. 4.
