Heat exchanger inlet and outlet pipes
Thread Content
When there is a significant difference in the density of the materials at the inlet and outlet of the heat exchanger, should the pipe diameters be calculated separately? ? Can inlet and outlet pipes of different diameters be used? ?
There is a phase change during the condensation process, so the diameters of the inlet and outlet pipes must be different； The calculation is also relatively simple
The pipe diameter is related to the flow rate and velocity; since the densities differ significantly, the appropriate flow velocities will also vary, so the pipe diameter needs to be calculated separately
The diameter of the pipes affects the flow velocity at the inlet and outlet, which in turn influences the pressure drop in the heat exchanger. Some heat exchangers have 2 inlets and 1 outlet; moreover, when condensation occurs with phase change, the densities will definitely differ significantly
They can definitely have different sizes, and even a different number of inlets and outlets; it mainly depends on the fluid flowing in and out and the operating conditions
