Fresh long-distance transportation, high and low external temperature environment, easy to lead to product deterioration. With the rapid change of external temperature, our company began to consider the design of thermal insulation cover, so as to realize the slow change of internal temperature of products and reduce the adverse impact caused by temperature difference.
The main principle of maintaining temperature balance and slow change of the insulation cover is the three elements of heat transfer: radiation, conduction and convection.
1. The aluminum film on the surface of the heat insulation cover can reflect off more than 92% of the solar radiation.
2. There is a certain gap between the heat shield and the product, which can reduce heat conduction.
3. Aluminum foil and thermal insulation material composite, has good thermal insulation performance.
4. Composite insulation material has good barrier performance, reduce the entry of dust and water vapor.
