There are significant differences between thermal oil and thermal adhesive film in multiple aspects. The following is a detailed comparison of the two:
1、 Definition and purpose
1. Thermal oil
Definition: Thermal oil is a type of specialized oil with good thermal stability used for indirect heat transfer, characterized by high heat transfer, high temperature resistance, high pressure resistance, and non-toxic and non corrosive properties.
Usage: Widely used in metallurgy, chemical fertilizer industry, metal heat treatment, textile printing and dyeing industry, food industry, wood processing industry and other fields, as fuel for heating furnaces or for transferring heat sources.
2. Thermal conductive adhesive film
Definition: Thermal conductive adhesive film is a material with efficient heat dissipation performance, usually used to conduct the heat generated by electronic components to the heat sink or radiator.
Usage: Mainly used in the electronics industry, lighting industry, automotive industry and other fields, such as CPU, chip, graphics card and other computer hardware, mobile phones, flat screen TVs, monitoring equipment and other electronic products for heat dissipation.
2、 Physical form and properties
1. Thermal oil
Physical form: Liquid, usually transferred by circulating heat through pipes.
Property: It has the characteristics of high thermal stability, low volatility, and low freezing point, and can work stably under high temperature and high pressure.
2. Thermal conductive adhesive film
Physical form: Solid state, usually in the form of a thin film, with a certain degree of flexibility and viscosity.
Property: It has excellent thermal conductivity, insulation performance, and aging resistance, and can efficiently conduct heat from electronic components to heat sinks.
3、 Heat transfer mechanism and efficiency
1. Thermal oil
Heat transfer mechanism: Heat is transferred through convection and conduction of liquids, usually forming a closed loop system with heating and cooling devices.
Efficiency: High heat transfer efficiency, suitable for large-scale and high-efficiency heat dissipation needs.
2. Thermal conductive adhesive film
Heat transfer mechanism: Heat is transferred through the thermal conduction of solid materials, usually directly attached between electronic components and heat sinks.
Efficiency: The heat transfer efficiency varies depending on factors such as material thickness and thermal conductivity, but it can usually meet the heat dissipation needs of small and precision electronic components.
4、 Application scenarios and limitations
1. Thermal oil
Application scenario: Suitable for industrial equipment that requires large-scale and high-efficiency heat dissipation, such as metallurgical furnaces, chemical reactors, heat treatment equipment, etc.
Limitations: A comprehensive circulation system needs to be established, and attention should be paid to preventing leakage and contamination during use.
2. Thermal conductive adhesive film
Application scenario: Suitable for heat dissipation of small and precision electronic components, such as CPUs, chips, graphics cards, etc.
Limitations: Due to material thickness and thermal conductivity, it may not be possible to meet large-scale, high-efficiency heat dissipation requirements.
In summary, there are significant differences between thermal oil and thermal adhesive film in terms of definition and application, physical form and properties, heat transfer mechanism and efficiency, as well as application scenarios and limitations. In practical applications, suitable heat dissipation materials should be selected according to specific needs and conditions.
