So what are the special features of refrigerated trucks compared to ordinary trucks? Refrigerated car manufacturers to give you a simple introduction.
In terms of structure, refrigerated trucks can usually be divided into three parts: automotive chassis, insulation cabin and refrigeration unit.
Car chassis:
To drive on the road, the car chassis is a natural part. In general, refrigerated trucks mainly have two forms of bicycles and trailers, mainly depending on the tonnage and demand choices of the goods to be loaded.
Generally, there are fewer goods loaded in short-distance distribution in urban areas or between counties and counties. There are more medium- and light-duty trucks, and the general transportation volume for long-distance transportation is also relatively large. The medium and heavy trucks are used, or refrigerated trucks in the form of semi-trailers are used. .
What should you watch out for when choosing a car chassis?
When selecting the automobile chassis, the user must consider the chassis's structure and carrying capacity, fuel economy, and emission standards according to the tonnage and road conditions of the cargo.
Compared with the choice of ordinary truck chassis, refrigerated trucks also need to focus on the stability of the chassis, refrigerated trucks transport goods are usually not long-term preservation of the goods, although there is refrigeration equipment, still need to reach the destination faster. At the same time, refrigerated goods have higher requirements for the transport environment. If there is a failure on the road, the goods will deteriorate and the loss will be very high.
â— Choice of refrigerator body:
The body of a refrigerated truck is different from an ordinary van, and it needs good sealing performance and heat insulation effect, so as to ensure that the refrigerated cargo is in a stable temperature environment.
The design of refrigerated compartments is mainly airtight and thermal insulation. Generally, the structure of refrigerated trucks adopts a three-layer structure. The inner and outer skins are made of composite materials, such as glass steel plates and aluminum alloys. The inner plate material should be made of different materials for transporting different goods. The most expensive inner material plate should be a stainless steel plate. The middle sandwich is a heat-insulating material, and polyurethane foam is mainly used. On the four sides, the glass plate and the polyurethane foam are bonded together with a high-strength adhesive to form a closed plate.
Thickness of refrigerated compartment:
In addition to materials, the thickness of the cargo compartment also determines the effectiveness of the insulation. The thicker the insulation layer of the cargo compartment, the better the insulation effect. However, the space inside the cargo compartment will be reduced, and the load of the cargo will be reduced. Users need to follow their own actual conditions. Need to choose the appropriate thickness.
Special requirements for refrigerated compartments:
In addition, different goods have different requirements for the car body. For example, refrigerated trucks that carry fresh meat need to be custom-made hooks on the car body; refrigerated trucks that distribute fresh food for the stores have small batches, many varieties, and require multi-temperature refrigerated trucks; the temperature needs are different, and frequent loading and unloading require more refrigerated trucks. All of these, the user can customize the car body according to specific needs.
