1. The "eddy current hot film heat exchanger" is extended into the bottom of the oil tank along the radial direction of the tank. The heat medium (steam) flows through the tube side. The oil flows from the tube to tube in the shell side. The oil suction port of the shell is directly connected with the medium in the tank.
2. A temperature control valve is set at the steam inlet of the heat exchanger to control the steam inlet of the heat exchanger through the detection of the oil outlet temperature by the temperature sensing probe, so as to ensure the constant oil temperature.
3. The heat exchanger adopts high-efficiency heat exchange element eddy current hot film tubes to keep the oil flowing reasonably between the tubes. The thermal efficiency is 3-5 times that of ordinary heat exchangers. Its enhanced heat transfer mechanism is: when the oil fluid flows on the internal and external surfaces, it is designed to be turbulent flow, producing strong shock and scouring effects, and the flow direction is constantly changing. The high-temperature oil fluid close to the surface of the tube wall is constantly replaced, and the insulation layer is thinner and even damaged, The heat transfer on the metal surface is accelerated, and the micro eddy current of the fluid is strengthened, so that the internal heat diffusion of the oil fluid is strengthened. The fluid close to the pipe wall surface will not cause local high temperature overheating, so the oil can be properly and fully heated without coking and decomposition. It has good heat transfer without great resistance.
