How does a heat exchanger transfer heat?
Author:
Summary:
In a typical shell-and-tube heat exchanger, heat transfer mainly occurs through conduction and convection. The hot fluid first transfers heat to one side of the tube wall through convection, then the heat is conducted from one side of the tube wall to the other side, where the other side of the tube wall transfers heat to the cold fluid through convection, thus completing the heat transfer process of the heat exchanger.
How does a heat exchanger transfer heat?
In a typical wall-type heat exchanger, heat transfer mainly occurs through conduction and convection. The hot fluid first transfers heat to one side of the tube wall through convection, then the heat is conducted from one side of the tube wall to the other side, and the other side of the tube wall transfers heat to the cold fluid through convection, thus completing the heat transfer process of the heat exchanger.
The higher the flow rate of the medium in the heat exchanger, the greater its heat transfer coefficient. Therefore, increasing the flow rate of the medium in the heat exchanger can significantly improve the heat exchange effect, but the negative impact of increased flow rate is that it increases the pressure drop across the heat exchanger and increases the energy consumption of the pump, so there should be a suitable range.
