Description

Technical Field

[0001] The utility model relates to a heating system, in particular to an expansion tank of a heat-conducting oil furnace. Background Art

[0002] The thermal oil furnace directly inserts the electric heater into the organic carrier (thermal oil) for direct heating, and transports the heated thermal oil to the heat-using equipment through the liquid phase circulation of the high-temperature oil pump, and then returns to the electric heating oil furnace from the oil outlet of the heat-using equipment for heating, forming a complete circulation heating system. The electric heating thermal oil furnace uses a digital temperature controller to control the temperature, and has over-temperature alarm, low oil level alarm, and over-pressure alarm functions. However, the current thermal oil furnace system lacks the necessary expansion structure, which is not conducive to accommodating the thermal expansion of the heat transfer fluid. In addition, the excess expansion of the heat transfer fluid when heated poses a large safety hazard and urgently needs to be improved. Utility Model Content

[0003] In order to solve the above problems, the utility model aims to provide an expansion tank for a thermal oil furnace.
