Abstract

The invention discloses a heat conduction oil heater which comprises a heater body, an oil sealing device and a sealing portion. The heater body comprises an oil groove, heat conduction oil is contained in the oil groove, the oil groove is provided with at least one air outlet, the oil sealing device is arranged to correspond to the air outlet and comprises a vent pipe which is used for exhaustingexpansion gas in the oil groove when the heater body works, and the sealing portion is used for sealing a channel which enables the vent pipe to communicate with the air outlet. When the heater bodydoes not work, the air pressure in the oil groove is small, and the sealing portion seals the air outlet. When the heater body works, the air pressure in the oil groove is increased, expansion gas ejects out a sealing body of the sealing portion, the vent pipe communicates with the air outlet, and expansion gas is exhausted through the vent pipe. The heat conduction oil heater avoids defects of anopening type system and has the advantages of the opening type system of being simple in structure and easy to operate and saving the maintenance and operation cost.

Description

technical field [0001] The invention relates to the field of fluid heating, in particular to a heat conduction oil heater. Background technique [0002] The heat conduction oil heater uses heat conduction oil as the heat carrier, and uses a circulating pump to circulate the heat conduction oil in the oil tank to receive heat evenly, and then the heat conduction oil transfers heat energy to the equipment or medium that needs to be heated. [0003] Traditionally, there are mainly two types of heat transfer systems for heat transfer oil heaters, which are open systems and closed systems. In the open system, an exhaust pipe is arranged on the oil tank. When the heat transfer oil heats up and expands, the gas can be discharged through the exhaust pipe, which saves equipment maintenance and operation costs, and the operation is relatively simple. Now nearly 90% of domestic heat transfer oil heaters use this heat transfer system. Closed systems usually use an inert gas to isolate...
