A heat exchanger is an energy-saving device that achieves heat transfer between materials between two or more fluids at different temperatures. It is to transfer heat from a fluid with a higher temperature to a fluid with a lower temperature, so that the temperature of the fluid reaches the index specified in the process to meet the needs of process conditions, and it is also one of the main equipment to improve energy utilization. The heat exchanger industry involves more than 30 industries including HVAC, pressure vessels, reclaimed water treatment equipment, chemicals, and petroleum.
The heating of the oil in the heat exchanger generally uses steam or electric heating. Oil cooling is generally just forced air-cooled or water-cooled. The cooler used more in the heat exchanger hydraulic system is a forced convection multi-tube cooler. The oil flows in from the oil inlet and flows out from the oil outlet; the cooling water flows in from the water inlet, heat exchanges with the oil through multiple water pipes, and then flows out from the water outlet. The role of the heat exchanger separator is to make the oil flow longer outside the water pipe, so that the heat exchange effect is better. The finned tube cooler is 8 to 10 times larger than the smooth tube with many radial fins nested on the outside of the round or oval tube. The heat dissipation effect of the elliptical tube of the heat exchanger is generally better than that of the round tube.
