Shell and Tube Heat Exchanger

Shell And Tube Heat Exchangers are devices that transfer part of the heat from
the hot fluid to the cold fluid, allowing hot water to flow through the pipe
due to the temperature difference between the hot water in the pipe and the
cold water in the container.
Wall heat exchanger
Two fluids with different temperatures flow in the space separated by the wall,
and heat is exchanged between the two fluids through the heat conduction of the
wall and the convection of the fluid on the wall surface.
Regenerative heat exchanger
Heat is transferred from high temperature fluid to low temperature fluid
through the heat accumulator composed of solid material, so as to achieve the
purpose of heat transfer.
