Controlled Temperature Trailer for Safe and Secure Transport of Chilled and Frozen Goods

The refrigerated semi-trailer is a type of semi-trailer used for transporting temperature-sensitive goods. Its structure mainly consists of the following parts:

1. Chassis: The chassis of the refrigerated semi-trailer is usually made of steel or aluminum, which has sturdy construction and strong load-bearing capacity.

2. Thermal insulation layer: To ensure the stable temperature inside the trailer, the thermal insulation layer of the refrigerated semi-trailer uses high-density insulation materials, such as polyurethane foam and sandwich panels.

3. Cooling equipment: Refrigerated semi-trailers are typically equipped with refrigeration units or cooling equipment to adjust the temperature inside the trailer according to the needs of different cargo.

4. Doors and windows: The doors and windows of the refrigerated semi-trailer are usually made of double-layered glass or plastic materials to ensure insulation and comfort.

5. Cargo fixing devices: To prevent cargo from sliding or tilting during transportation, refrigerated semi-trailers are typically equipped with special cargo fixing devices, such as airline tracks and straps.

6. Lighting and electrical systems: The lighting and electrical systems of refrigerated semi-trailers include interior lighting, brake lights, turn signals, temperature control systems, etc.

In summary, the structural design of refrigerated semi-trailers aims to provide temperature and humidity control for cargo, ensuring its quality and safety during transportation.
