Each of the heating zones includes a heating chamber and a heater. The heating chamber is respectively provided with an oil inlet and an oil outlet. The heating chambers of each heating zone are connected in series in sequence.

Each of the heating chambers and the buffer tank is provided with an insulation layer. Each of the heaters and temperature sensors is electrically connected to the control unit. The thermal oil furnace has the beneficial effects of accurate heating, energy saving, and being able to increase the service life of the thermal oil.

[0004] Although the above-mentioned thermal oil furnace can heat accurately, the heating efficiency is low, and the uneven heating of the thermal oil leads to poor heat conduction effect. Utility Model Content
