Product Description

The most important performance of refrigerated trucks is thermal insulation. The insulation performance depends largely on the insulation performance of Freezer Sandwich Panels. There are mainly two types of panels widely used in refrigerated trucks in the market: metal skin and glass fiber reinforced plastic(FRP) skin. The refrigerated trucks with FRP skin, with its excellent heat insulation capacity, smooth and easy-to-placing appearance, and excellent mechanical strength, make it occupy a very large market share in the refrigerated truck wall panels.

The core materials of Freezer Sandwich Panels used in refrigerated trucks are mainly as follows: EPS, XPS and PU. Each core material has different characteristics. PU has the most excellent thermal insulation function, which is mainly used in refrigerated trucks with very high thermal insulation requirements, but its cost is relatively high. XPS also has excellent thermal insulation properties, and its cost is more economical than PU. At the same time, due to its excellent mechanical properties, it has the widest application range in refrigerated trucks. Although EPS has excellent thermal insulation properties and relatively cheap raw materials, but because its mechanical properties are not very good, so relatively few used in refrigerated truck applications.

When we buy Freezer Sandwich Panels, we need to pay attention to the following points

1. Whether the FRP board and the core material are bonded firmly, there is no cracking in the bonding area and the board is not obviously bulging;

2. Whether the surface of the FRP board is smooth and flat;

3. When purchasing a sheet with XPS as the core material, make sure that the core material has sufficient strength and XPS cannot be easily compressed.

In the design of refrigerated trucks, we need to pay attention to the control of the cold bridge. The cold bridge has a destructive effect on the insulation of refrigerated trucks. It will increase the cold consumption of refrigerated trucks and increase the fuel consumption of refrigerated trucks.

Since a large amount of the cold energy felt by the surface of the structure near the cold bridge is concentrated in the cold bridge part, the cold energy loss caused by the cold bridge greatly exceeds the value calculated simply by its cross-sectional area. The existence of cold bridge not only causes heat loss in refrigerated trucks, but also the part of the cold bridge becomes a weak link of the insulation structure, causing condensation, frost, icing, and moisture failure of the insulation structure on the higher temperature side of the insulation structure. , In severe cases, the structural layer is damaged by freezing.
