How are the inlet and outlet of a heat exchanger determined?
The hot medium enters at the top and exits at the bottom, while the cold medium enters at the bottom and exits at the top.
The hot medium enters at the top and exits at the bottom, while the cold medium enters at the bottom and exits at the top. But our heat transfer oil follows a low-in, high-out principle.
The flow rate and velocity can be determined from the diameter size
Steam heating, high inlet low outlet； Liquid heating: low inlet, high outlet ； Cooling always involves low inlet and high outlet ； As for how to determine which mouths you’re talking about, just cover the two identical mouths and use the other two instead
Generally, there is counterflow between hot and cold fluids: the hot fluid enters at a higher level and exits at a lower level, while the cold fluid enters at a lower level and exits at a higher level. The fluid for the tube side and shell side is determined based on the properties of the medium; fluids that tend to form scale are used on the tube side
