Description

Technical Field

[0001] This utility model relates to the field of thermal insulation pad technology, and in particular to aluminum-plastic refrigerated truck thermal insulation pads. Background Technology

[0002] Refrigerated trucks, as the most common means of transportation in the cold chain transportation field, have become an indispensable product for cold chain logistics companies due to their real-time refrigeration and full-truckload transportation features. They play an irreplaceable role, especially for full-truckload refrigerated cargo transportation. As the demand for cold chain transportation increases, its form is also changing, from full-truckload transportation to less-than-truckload (LTL) small-volume transportation, facing the objective need for multi-temperature zoning in actual operation.

[0003] Traditional insulation panels have been used for logistics partitioning. However, due to the inherent structural characteristics of refrigerated trucks, such as the need for circulating cold air at the bottom of the compartment, iron channels are welded to the bottom of the compartment before the truck leaves the factory. Because these cold air channels vary in size, there is no good way to physically protect and isolate them, which causes cold air to leak from below, resulting in significant damage to goods in different temperature zones. Therefore, the design of aluminum-plastic refrigerated truck insulation pads is particularly important. Utility Model Content

[0004] The purpose of this utility model is to provide an aluminum-plastic refrigerated truck insulation pad to solve the problem mentioned in the background art that the cold air ducts have different specifications and therefore there is no good way to physically protect and isolate them, resulting in cold air leaking from below.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum-plastic refrigerated truck insulation pad, comprising an insulation pad body, the insulation pad body having edging cloth around its perimeter, pearl cotton on the surface of the insulation pad body, multiple cold air duct pendants on the surface of the pearl cotton, two Velcro straps on the surface of the pearl cotton, and a polyethylene foam board on the back of the insulation pad body.

[0006] As a preferred technical solution of this utility model, the interior of each of the multiple cold air channel pendants is filled with a rectangular strip of high-elastic cotton, and the two Velcro straps are bonded together.

[0007] As a preferred embodiment of this invention, the multiple cold air duct pendants are arranged at equal intervals.

[0008] As a preferred technical solution of this utility model, the edging fabric is sewn around the perimeter of the heat insulation pad body, and the bottom surfaces of the two Velcro fasteners are respectively bonded to the surface of the pearl cotton.

[0009] As a preferred embodiment of this utility model, the two Velcro straps are symmetrically distributed around the center of the heat insulation pad body.

[0010] As a preferred embodiment of this invention, multiple cold air duct pendants are respectively filled inside the cold air duct.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] This utility model relates to an aluminum-plastic refrigerated truck insulation pad. It incorporates a binding fabric, cold air duct pendants, pearl cotton, Velcro, polyethylene foam board, and high-elastic cotton rectangular inserts. The binding fabric, made of polyester fiber, provides good wear resistance and wrinkle resistance, is easy to clean, and extends the lifespan of the insulation pad. The high-elastic cotton rectangular inserts fill the interior of the cold air duct pendants, which in turn fill the interior of the cold air ducts, thereby improving… The air-insulating effect of aluminum-plastic refrigerated trucks reduces the cross-flow of cold air between different temperature zones, thus reducing cargo damage. The insulation pad itself can be rolled up, reducing storage space and facilitating transportation. Pearl cotton has heat-insulating, waterproof, and moisture-proof properties, effectively blocking temperature transfer from the metal structure of the cold air duct itself. Polyethylene foam board reduces the coefficient of friction on the back of the insulation pad, allowing pallets to slide smoothly when in contact with the surface, making it easy to drag and reducing damage to the insulation layer caused by the rough structure of the pallet surface, significantly extending its service life.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3This utility model provides a technical solution for aluminum-plastic refrigerated truck insulation pads:

[0019] like Figure 1-3 As shown, the aluminum-plastic refrigerated truck insulation pad includes an insulation pad body 1, with edging fabric 5 around the perimeter of the insulation pad body 1, pearl cotton 11 on the surface of the insulation pad body 1, multiple cold air duct pendants 10 on the surface of the pearl cotton 11, and two Velcro straps 12 on the surface of the pearl cotton 11. A polyethylene foam board 13 is located on the back of the insulation pad body 1. The edging fabric 5 is sewn around the perimeter of the insulation pad body 1. The bottom surfaces of the two Velcro straps 12 are respectively adhered to the surfaces of the pearl cotton 11. The two Velcro straps 12 are symmetrically distributed around the center of the insulation pad body 1. The multiple cold air duct pendants 10 are filled inside the cold air ducts. The air duct pendants 10 are filled inside the cold air ducts to improve the air insulation effect of the aluminum-plastic refrigerated truck, reduce the occurrence of cold air cross-flow between different temperature zones, and reduce the resulting cargo damage. The insulation pad body 1 can be rolled up as a whole, reducing storage space and facilitating transportation and carrying. The pearl cotton 11 has the characteristics of heat preservation, waterproofing and moisture resistance, which can effectively block the temperature transfer from the metal structure of the cold air duct itself. The polyethylene foam board 13 can reduce the coefficient of friction on the back of the insulation pad body 1, so that the cargo pallet can slide smoothly when in contact with the surface, making it easy to drag, reducing the damage to the insulation layer caused by the rough structure of the pallet surface, and greatly improving the service life.

[0020] Working Principle: Refrigerated trucks, as the most common transport vehicle in the cold chain transportation field, rely on their real-time refrigeration combined with full-truckload transportation characteristics, making them an indispensable product for cold chain logistics companies. They play an irreplaceable role, especially in full-truckload refrigerated cargo transportation. With the increasing demand for cold chain transportation, its form is also changing, from full-truckload transportation to less-than-truckload (LTL) small-volume transportation. In actual operation, facing the objective need for multi-temperature zoning, traditional insulated areas have been used for logistics zoning. However, the internal structural characteristics of refrigerated trucks, such as the need for cold air circulation at the bottom of the compartment, present challenges. In refrigerated trucks, metal ducts are welded to the interior floor of the cargo compartment before the vehicle leaves the factory. Because these ducts vary in size, there's no effective way to physically protect and isolate them, causing cold air to leak from below, resulting in significant damage to goods in different temperature zones. Therefore, designing an aluminum-plastic refrigerated truck insulation pad is crucial. Using sewing equipment, edging fabric 5 is sewn around the perimeter of the insulation pad body 1, effectively binding the edges. The edging fabric 5 is made of polyester fiber, which has good wear resistance and wrinkle resistance, and is easy to clean, extending the service life of the insulation pad body 1. High-elastic cotton rectangular... The plug strips 14 are respectively filled inside the cold air duct pendants 10, thereby improving the air insulation effect of the aluminum-plastic refrigerated truck, reducing the occurrence of cold air cross-flow between different temperature zones, and reducing the resulting cargo damage. The insulation pad body 1 can be rolled up as a whole, reducing storage space and facilitating transportation and carrying. The pearl cotton 11 has heat insulation, waterproof and moisture-proof properties, which can effectively block the temperature transfer from the metal structure of the cold air duct itself. The polyethylene foam board 13 can reduce the coefficient of friction on the back of the insulation pad body 1, so that the cargo pallet can withstand the friction when in contact with the surface. Smooth and easy to drag, reducing damage to the insulation layer caused by the rough surface structure of the tray, significantly extending service life. The surface aluminum-coated composite material has insulation properties, reducing heat loss. The insulation pad adopts a pendant structure, with high-elastic cotton rectangular plugs 14 inserted into each air duct pendant 10. This structure can match the air ducts of different car models, thereby providing insulation capabilities and reducing the loss rate to 0.2%. Environmentally friendly aluminum-plastic composite material is used for structural sewing, and high-elastic cotton rectangular plugs 14 are inserted into each air duct pendant 10. The sealing is further processed by adhesive sewing.
