Box
The box of a box-type refrigerated semi-trailer is generally made of steel, aluminum alloy, or fiberglass, and is corrosion-resistant, waterproof, and fire-resistant. The interior space of the box is used to store cargo, so it must have a certain load-bearing capacity and space utilization. Furthermore, the box must have good thermal insulation and sealing properties to ensure the quality and safety of the cargo during transportation.
Chassis
The chassis of a box-type refrigerated semi-trailer is the main structure supporting the entire vehicle and is generally made of steel. The chassis design must take into account the stability and load-bearing capacity of the entire vehicle to ensure safety during operation. Furthermore, the chassis must have certain rust and corrosion resistance properties to extend the vehicle's service life.
Refrigeration Equipment
Box-type refrigerated semi-trailers require refrigeration equipment to ensure the temperature of the cargo during transportation. There are many types of refrigeration equipment, including mechanical, compression, and absorption. The selection of these types of equipment should be based on the specific cargo requirements and transportation environment. Refrigeration equipment must also be energy-efficient to reduce operating costs.
Insulation Materials
The insulation materials of box-type refrigerated semi-trailers are primarily used to protect cargo from external temperature influences. Numerous types of insulation materials are available, including polyurethane foam, rock wool, and glass wool. The selection of these materials should be based on specific temperature requirements and insulation performance. Insulation materials also need to possess certain moisture-proof, mildew-proof, and fire-resistant properties.
In summary, the main components of a box-type refrigerated semi-trailer include the box, chassis, refrigeration equipment, and insulation materials. The design and selection of these components must take into account the specific characteristics of the cargo and the requirements of the transportation environment to ensure the quality and safety of the cargo during transportation.
