The density of thermal oil varies depending on the type, usually ranging from 800 to 1000 kg/m ³.

1、 What is thermal oil?

Thermal oil is a special liquid, usually an organic compound or mineral oil. Its main function is to transfer heat energy at high temperatures, commonly used in industrial production processes such as heating, cooling, and drying. It can be used in the temperature range of -20 ℃ to 350 ℃, with high thermal conductivity and good stability.

2、 Density data of thermal oil

The density of different types of thermal oil may vary, generally ranging from 800 to 1000 kg/m ³. The specific data is as follows:

1. High temperature synthetic thermal oil: with a density of about 900 kg/m ³, it is mainly composed of polycyclic aromatic hydrocarbons, hydrogenated cracking products, and aliphatic synthetic oils, and is commonly used for heat transfer under high temperature conditions.

2. Polymer thermal oil: with a density of about 1000 kg/m ³, mainly composed of polymer and a small amount of high boiling point solvent. It has high thermal conductivity and low toxicity, suitable for heat transfer under high temperature, high pressure, and low temperature conditions.

3. Mineral oil heat transfer oil: with a density of about 850 kg/m ³, it is mainly composed of refined mineral oil from petroleum distillation, distilled paraffin, etc. It is suitable for heating, cooling, drying and other operations in industrial production processes.

3、 The influence of thermal oil density

The density of thermal oil will affect its fluidity and heat transfer efficiency during the heat transfer process. Heat transfer oils with higher density have heavier weight, higher viscosity, and lower heat transfer efficiency, but they have higher stability in transferring heat energy; On the contrary, heat transfer oils with lower density have lighter weight, lower viscosity, and higher heat transfer efficiency, but their stability in transferring heat energy is poor. Therefore, when selecting heat transfer oil, it is necessary to comprehensively consider different factors and choose according to specific situations.

This article mainly introduces the definition, use, and density of thermal oil, and compares the density data of different types of thermal oil. In practical applications, it is necessary to choose the appropriate heat transfer oil according to the specific situation to ensure its stability and heat transfer efficiency.
