油加热器工作原理
Working principle of oil heater
对于油加热器，热量是由浸入导热油的电加热元件产生和传输的，以导热油为介质，利用循环泵，强制导热油进行液相循环，将热量传递给用一个或多种用热设备，经用热设备卸载后，重新通过循环泵，回到加热器，再吸收热量，传递给用热设备，如此周而复始，实现热量的连续传递，使被加热物体温度升高，达到加热的工艺要求。
For the oil heater, the heat is generated and transmitted by the electric heating element immersed in the heat-transfer oil. With the heat-transfer oil as the medium, the circulating pump is used to force the heat-transfer oil to circulate in the liquid phase and transfer the heat to one or more heat using equipment. After unloading the heat using equipment, the heat is returned to the heater through the circulating pump, and then absorbed and transferred to the heat using equipment, so on. The continuous heat transfer is realized, the temperature of the heated object is increased, and the heating process requirements are met.
