Thermal radiation sheet | Practical accessory to assist equipment in low-temperature operation

Introduction

In many fields such as precision electronics, LED lighting, automotive electronics, etc., efficient heat dissipation of equipment is the core challenge to ensure its stable performance and long lifespan. Traditional active heat dissipation (such as fans) or conductive heat dissipation (such as metal heat sinks) are effective, but they are inadequate in scenarios where space is limited, silence is required, or passive heat dissipation is required.Advanced Institute (Shenzhen) Technology Co., LtdThe thermal radiation plate, as a passive thermal management material, provides a clever and efficient solution for stable operation of equipment in low-temperature environments by enhancing its surface thermal radiation capability.

1、 Working principle of thermal radiation film

Advanced Institute of TechnologyThermal radiation filmIt is usually non-conductive, insulating, and soft, lightweight, and filled with ceramic particles or other functional fillers with high emissivity (usually up to 0.9 or higher) inside. When attached to the surface of a heating element, it is not a conventional "thermal conductive" material, but plays the role of an "energy converter": it efficiently converts the heat conducted from the inside of the element to the surface into far-infrared radiation energy, which is emitted into a wider surrounding space environment, thereby greatly improving the final heat dissipation efficiency.

2、 Core functional features

1. Improve radiation heat dissipation efficiency: Its fundamental function is to convert the low emissivity of the object surface into a high emissivity, doubling the amount of radiation heat dissipation, especially in closed environments with weak convection, where the effect is significant.

2. Achieving temperature balance: By promoting the radiation exchange of heat, it helps to reduce local hotspots inside the equipment, make the temperature distribution more uniform, and avoid overheating of a single component.

3. Passive operation: No external energy drive required, no noise generated, extremely high reliability, truly achieving "zero" energy consumption for heat dissipation.

4. Easy and flexible installation: It usually comes with adhesive backing, which can be directly attached to the surface of the heat source shell or radiator like a sticker, suitable for various shapes and irregular surfaces, with almost no additional volume and weight added.

3、 Typical application scenarios

1. Enclosed electronic equipment chassis: In enclosed enclosures such as communication base stations, industrial control computers, servers, etc., air convection is limited, and thermal radiation fins can effectively enhance the outward radiation heat dissipation of the enclosure and reduce the internal environmental temperature.

2. In the field of LED lighting: high-power LED fixtures, especially enclosed structures such as bulb lights and projection lights, can accelerate heat radiation outward by attaching heat radiation sheets on the inside of the lamp cup, significantly delaying light decay and extending service life.

3. Automotive electronics: Applied to heating units such as automotive LED light controllers (ECU) and battery management systems (BMS), helping them maintain lower operating temperatures in high-temperature environments such as engine compartments.

4. Consumer electronics products, such as routers, network switches, smart speakers, etc., are used to assist in heat dissipation and improve device stability in the pursuit of lightweight and silent design.

4、 Advantages

1. Lightweight and Silent: It takes up almost no space, has no moving parts, and is absolutely silent.

2. Safe and reliable: insulation, high temperature resistance, corrosion resistance, no risk of failure.

3. Energy saving and environmental protection: It works completely passively without additional energy consumption.

4. High cost-effectiveness: Effectively improving the product's heat dissipation redundancy and reliability at a lower cost.

Summary

Advanced Institute (Shenzhen) Technology Co., LtdHigh emissivity infrared materialsNot by directly conducting heat to cool down, but by improving the surface heat radiation efficiency, it has opened up a new heat dissipation path for the device. It plays an irreplaceable role in specific heat dissipation bottleneck scenarios due to its unique value of being passive, silent, lightweight, and reliable. As an efficient and economical auxiliary heat dissipation method, heat radiation fins have become an important member of the modern electronic device thermal design toolbox, effectively assisting various devices in stable and efficient operation at low temperatures.
