Problems solved by technology

[0003] There are many types of heat transfer oil. The heat transfer oil currently used is mainly processed from petroleum products. With the continuous rise of international oil prices, the cost of using traditional heat transfer oil is getting higher and higher.
Moreover, in recent years, the governments of various countries have paid more and more attention to the environment, and vigorously advocated the concepts of "green GDP" and "environmental sustainable development". The problem is becoming more and more prominent. The recycling of various "oil products" is one of the difficulties. The process is complex and requires a lot of financial and material resources, and the recycling cost is very high.

Embodiment 1

[0025] Oil heating heater is one of the mainstream household heating equipment in the market. It has the advantages of large heat dissipation, long heat preservation time after power failure, and no electrical operation noise. It is mainly composed of sealed electric heating elements, metal heat dissipation pipes or fins, temperature control elements, Composition of indicator lights, etc. This kind of heater is that the electric heating tube is installed under the cavity with many cooling fins, and heat conducting oil is injected around the electric heating tube in the cavity. After the power is turned on, the heat transfer oil is heated and rises to the upper part of the cavity, convectively circulates along the heat dissipation pipes or fins, and radiates heat through the wall surface of the cavity to heat the space environment. The heat transfer oil cooled by the air descends to the electric heating tube and is heated again to start a new cycle.

Abstract

The invention relates to a preparation method and application of aqueous environmentally-friendly type conduction oil in which glycerol is used as a main component, belonging to the field of heat conduction media. According to the invention, the conduction oil contains about 95% by mass of glycerol; the novel conduction oil is extremely environmentally-friendly, can be miscible with water in any proportion and does not contain any toxic and harmful substances, can be discharged without any special treatments, and has the advantages of wide material sources, low price and simple processing technology; and simultaneously, the conduction oil can operate for a long term at high temperature. The novel conduction oil is successfully used on an oil heater type warmer, and can also be popularized to other related industries at the same time.

Description

technical field [0001] The invention belongs to the field of heat conduction medium, in particular to a water-soluble environment-friendly heat conduction oil mainly composed of glycerin. Background technique [0002] Heat transfer oil, also known as heat transfer oil, is a heat transfer medium. Because of its uniform heating, accurate temperature control and temperature control, it can generate high temperature under low vapor pressure, good heat transfer effect, energy saving, convenient transportation and operation. The equipment has the characteristics of no corrosion, etc., and has been widely used in various occasions in recent years, and its use and consumption are increasing. [0003] There are many types of heat transfer oil. The heat transfer oil currently used is mainly processed from petroleum products. With the continuous rise of international oil prices, the cost of using traditional heat transfer oil is getting higher and higher. Moreover, in recent years, th...
