Description
The present invention relates to a kind of heat-conduction medium, particularly a kind of heat-conducting oil for electric heating device.
Existing thermal oil mostly is the thermal oil that uses under the high temperature, as heat-transfer medium, is widely used in heat recuperation such as reactor, process furnace, device.Thermal oil generally has following type: semi-synthetic oil, alcohol ether, organic silicone oil and the mineral wet goods of synthetic aromatic hydrocarbons, synthetic aromatic hydrocarbons and mineral oil.Select for use above-mentioned thermal oil generally only to consider following performance: (1) heat-resistant quality and oxidation stability; (2) heat conductivity; (3) low-temperature fluidity and flash-point; (4) toxicity and biological degradability, and when not considering electric simulation strength and heated sealed because of oil product and pressure that when gases are heated, they expand produces.Above-mentioned (1), (2), (3) performance of having thermal oil now are all better, but most of thermal oil all has some toxicity.The deficiency of its maximum is that electric simulation strength is lower, the pressure height that produces during heated sealed, thereby not to be suitable for the electricity be the plant and instrument of thermal source and the non-pressure vessel equipment that pressure is lower than 0.1MPa.In addition, existing thermal oil is synthetic oil mostly, and raw material sources are difficulty, and production technique is also complicated.
The oil-filling type electric heating warmer is the household electrical appliance that a kind of developed recently gets up, and is used for the severe cold area warming.This oil-filling type electric heating warmer profile is similar to the radiator of steam for heating, but it is heat source with the electricity, is heat-transfer medium with special-purpose thermal oil.The electric heating device volume is little, and is in light weight, can arbitrarily move.During use, behind the connection power supply, because the effect of thermal siphon, the thermal oil nature flows along conduit is upper and lower, and the moving phase of oil product makes whole electric heating actuator temperature even together in flow principles and the transformer, and heat is sent out.
Heat-conducting oil for electric heating device is compared with industrial thermal oil, except that good heat-conducting, detergent-dispersant performance energy and antioxygen, corrosion resistance will be arranged, also requires the pressure have when airtight heating low, the electric simulation strength height, and the flash-point height, carbon yield is low.
The purpose of this invention is to provide a kind of when airtight heating the low heat-conducting oil for electric heating device of pressure.
Another object of the present invention provides the high heat-conducting oil for electric heating device of a kind of electric simulation strength.
A further object of the present invention provides a kind of flash-point height, heat-conducting oil for electric heating device that carbon yield is low.
