Case Sharing of Thermal Pad and Thermal Gels Applied in the Medical Industry

With the rapid development of medical technology and electronic technology, advanced digital electronic equipment combined with analog circuits to provide medical functions, including diagnostic equipment. The number of electronic devices used in medical equipment has increased significantly. During the use of the equipment, the heating of the equipment has become one of the main factors that endanger its stability and reliability. However, the heating of the equipment in use is inevitable, because the energy When converted into target energy, part of the energy will loss, and a large part of this part of the energy will be lost in the form of heat. If the heat dissipation is not done in time, the surface temperature of the heat source will be too high and it will be lost, thus affecting the product. performance and use.

Thermal Pad

The 5G era means an increase in power consumption, and it also represents a test for heat dissipation. Normally, a heat sink installed above the heat source to guide heat into the heat sink, and the direct contact between the heat sink and the heat source is It is impossible to effectively dissipate heat, because there is a gap between the radiator and the heat source, and there is air in the gap. The air is a poor conductor of heat, and the heat transfer efficiency from the surface of the radiator to the radiator reduced, resulting in poor heat dissipation. Unable to achieve the expected effect.

Medical Industry

The 5G era means an increase in power consumption, and it also represents a test for heat dissipation. In order to effectively solve the problem of poor heat dissipation, thermal interface material have also emerged. Thermally conductive materials are a general term for many thermal gap filler materials, including thermal pad, thermal insulation film, thermal insulating sheets, thermal conductive gel, thermal paste / thermal grease, and silicon-free thermal conductivity. Sheets, thermal pads, thermal phase change materials, etc., and each thermal interface material has its own advantages and areas of expertise. But here Zhaoke recommends materials for heat dissipation in medical equipment: thermal silicone pad and thermal gel, which are mainly used between the radiator and the heat source to fill the gap between the interfaces, remove the air between the interfaces, and reduce the contact Thermal resistance, improve the heat transfer efficiency, thereby improving the heat dissipation effect.

thermal pad

Thermal conductive sheet fill the air gap between the heating element and the heat sink or metal base, and their flexible, elastic properties allow them to use to cover very uneven surfaces. The heat conducted from the separate device or the entire PCB to the metal casing or diffuser plate, thereby improving the efficiency and service life of the heat-generating electronic components.

Thermal pad product features:

  • Good thermal conductivity;
  • Self-adhesive without additional surface adhesive;
  • High compressibility, softness and elasticity, suitable for low pressure applications;
  • Various thickness options are available.
Thermal Gel

Thermal conductive gel has good thermal stability and electrical insulation, flexibility, elasticity and other properties, which makes it suitable for covering very uneven surfaces, and does not produce small molecules after curing, can reduce temperature and external pressure, and is provided in liquid form Various thicknesses. The automatic dispensing system can save time and worry, and greatly reduce the stress on the components during the assembly process. Some irregular heating elements may be helpless, but thermal gel can solve this problem very well. Condition.

Thermal Gel Product Features:

  • Good thermal conductivity;
  • Soft and almost no pressure between the device and the device;
  • Low thermal impedance;
  • It can be easily used for automatic operation of dispensing system;
  • Long-term reliability;
  • In line with UL94V0 fire rating.
