Matters needing attention in using tube heat exchanger

The structure of the tube heat exchanger is simple, but the protection in operation is very important. This is something that needs to be considered when adding the tube heat exchanger.


If the temperature difference between the cold and heat medium is large when the tube heat exchanger is operating, if the structure of the tube heat exchanger is a rigid structure, the fluid with a large heat transfer coefficient will pass through the tube heat exchanger during convection operation.

If the flow rate of the fluid applied to the tube heat exchanger is small and the viscosity is high, these fluids are directly passed through the shell side of the tube heat exchanger.


If the temperature of the hot fluid inlet and outlet meets the relevant requirements of the tube heat exchanger, the outlet temperature and flow rate of the cooling medium can be controlled. Need to make detailed selection based on the actual situation. 



For example, if the outlet temperature is relatively high, then we need to choose a small tube heat exchanger, but the flow rate of the cooling medium needs to be increased accordingly; secondly, if the outlet temperature is relatively low, then we need to choose a large tube heat exchanger. The tube heat exchanger and the flow of the cooling medium are correspondingly reduced. Therefore, at the time of selection, it is necessary to measure the detailed cooling medium according to the outlet temperature.


The tube type heat exchanger is more prone to problems. The medium flushes the pipe and the corrosion causes the pipe aging. Therefore, the heat exchanger is often checked and the medium needs to be filtered.
