High Performance Insulation Aerogel Felt for Cold Chain Logistics And Refrigeration Facilities

Good Price Aerogel Felt Used In The Cold Chain

Material structure and characteristics

• Nanoporous structure: Just like ordinary aerogel felts, it has a nanoscale pore structure. These tiny pores can effectively inhibit the thermal convection of gas molecules. It's difficult for air to flow freely in the pores, thus reducing one of the main ways of heat transfer. This microscopic structure gives the aerogel felt an extremely low thermal conductivity, usually around 0.013 - 0.018 W/(m·K), which provides a good foundation for cold chain insulation.

• Fiber reinforcement components: To increase the mechanical strength of the material, the aerogel felt usually contains fiber reinforcement components, such as glass fiber. These fibers are intertwined in the aerogel matrix, enabling the material to withstand certain external forces while maintaining good thermal insulation performance and avoiding being easily damaged during installation or use.

• Surface properties: The aerogel felt used in the cold chain usually also has good surface properties. For example, a smooth surface can reduce heat exchange when in contact with the external environment. Moreover, some aerogel felts also have certain moisture-proof and antibacterial properties to meet the complex requirements of the cold chain environment.

Application in cold chain logistics

• Insulation of refrigerated vehicles: Using aerogel felts in the insulation layer of the compartment of a refrigerated vehicle can effectively prevent heat exchange between the inside and outside of the compartment. When the refrigerated vehicle is in transit, whether on a hot summer highway or in a cold winter environment, the aerogel felt can maintain the low-temperature environment inside the compartment. Compared with traditional insulation materials, it can achieve the same insulation effect with a thinner thickness, which can increase the effective volume of the compartment and improve transportation efficiency. For example, refrigerated vehicles insulated with aerogel felts can better maintain the low-temperature environment required for perishable foods such as meat, seafood, and vegetables during transportation, extending the shelf life of the foods.

• Insulation of insulated boxes: For small cold chain insulated boxes, aerogel felts are also an ideal insulation material. They can be wrapped between the inner and outer walls of the insulated box to provide a stable low-temperature environment inside the box. Such insulated boxes are very important when transporting some pharmaceuticals, biological samples, etc. that require precise temperature control. The high-efficiency thermal insulation performance of aerogel felts can reduce the impact of changes in the external environment temperature on the temperature inside the box, ensuring the quality and safety of the items during transportation.

Application in refrigeration facilities

• Insulation of cold storage: In the wall, roof, and floor insulation systems of cold storage, aerogel felts play a crucial role. They can prevent heat transfer between the inside and outside of the cold storage and maintain the low temperature inside. Since cold storage usually needs to operate for a long time, the long-term thermal insulation stability of aerogel felts can reduce the energy consumption of refrigeration equipment and save energy costs. Meanwhile, its good moisture-proof performance can avoid the condensation phenomenon caused by the large temperature difference between the inside and outside of the cold storage and prevent the insulation layer from being damaged by moisture, thus prolonging the service life of the insulation system.

• Insulation of refrigerated display cabinets: In refrigerated display cabinets in supermarkets, convenience stores, and other places, aerogel felts can be used for the insulation of the back and sides of the cabinets. This helps maintain the low-temperature environment inside the display cabinets, reduces the starting frequency of the refrigeration compressor, lowers noise and energy consumption. And the thin design of the aerogel felts will not take up too much space inside the display cabinets, enabling the display area to better display refrigerated goods.
