Description
Technical Field
[0001] This application relates to the field of refrigerated truck compartments, and particularly to a wind guiding structure for refrigerated trucks. Background Art
[0002] A refrigerated truck is an enclosed van used to transport frozen or fresh goods. A refrigeration unit is installed inside the compartment, which can keep the temperature inside the compartment relatively low. By using a refrigerated truck to transport goods with high storage requirements such as food and medicine, the quality of the goods can be maintained in a better state.
[0003] A substrate is installed on the inner wall of the refrigerated truck compartment. The substrate is laid on the bottom and side walls of the compartment. The refrigeration unit is installed on the refrigerated truck and is used to fill the compartment with low-temperature gas to keep the temperature inside the compartment at a relatively low level.
[0004] The above-mentioned related technical solutions have the following defects: when the goods are placed against the inner side wall of the compartment, the bottom and side parts of the goods are in contact with the substrate, and it is difficult for the low-temperature air to contact the outer surface of the goods and conduct heat exchange, so that the goods are difficult to cool evenly, resulting in poor quality of the goods after refrigeration. Utility Model Content
[0005] In order to enable the goods to cool evenly in the compartment, this application provides a wind guiding structure for refrigerated trucks.
[0006] The wind guiding structure for refrigerated trucks provided by this application adopts the following technical solutions:
[0007] A wind guiding structure for refrigerated trucks includes a substrate and a plurality of wind guiding strips. The length directions of the wind guiding strips are parallel to each other. The wind guiding strips are fixedly installed on the substrate, and the plurality of wind guiding strips are arranged at intervals.
[0008] By adopting the above technical solution, by arranging a plurality of wind guiding strips on the substrate, when the goods are placed on the substrate, the wind guiding strips can support the goods, so that a gap is formed between the surface of the goods and the substrate. When the refrigeration unit of the compartment works, the low-temperature air can flow in the gaps between adjacent wind guiding strips, thereby increasing the contact area between the low-temperature air and the surface of the goods, enabling each surface of the goods to conduct heat exchange with the low-temperature air, and thus enabling the goods to cool evenly in the compartment.
[0009] Optionally, the length direction of the wind guiding strip points to the opening of the compartment.
[0010] By adopting the above technical solution, by making the length direction of the wind guiding strip point to the opening of the compartment, when condensate is generated in the compartment, the condensate can flow on the surface of the substrate and flow into the gaps between the wind guiding strips, thereby reducing the probability of the condensate contacting the bottom of the goods and reducing the probability of the condensate wetting the bottom of the goods. The user can conveniently and quickly remove the condensate from the gaps between the wind guiding strips out of the compartment, which is convenient for the user to clean.
[0011] Optionally, a groove is provided on the top surface of the air guide strip.
[0012] By adopting the above technical solution, by opening a groove on the air guide strip, when the bottom of the cargo abuts against the air guide strip, low-temperature air can circulate in the groove, further increasing the heat exchange area between the cargo compartment and the bottom of the cargo, and improving the cargo compartment's ability to keep the cargo fresh.
[0013] Optionally, a slope is provided at the end of the air guide strip, and the slope is located on a side of the air guide strip close to the cargo compartment opening.
[0014] By adopting the above technical solution, by providing a slope at the end of the air guide strip, and making the slope provided at the cargo compartment opening, when users are loading and unloading cargo, the probability of the corners of the air guide strip scratching the cargo surface can be reduced.
[0015] Optionally, a placement plate is provided on the air guide strip, the size of the placement plate is smaller than the size of the base plate, the placement plate cover is provided on the air guide strip, the placement plate is fixedly connected to the air guide strip, a plurality of through holes are opened on the placement plate, and the through holes are connected to the gaps between adjacent air guide strips.
[0016] By adopting the above technical solution, by arranging a placement board on the air guide strip, the user can stack the goods on the placement board, which is a flat plate and supports the goods. When the outer packaging of the goods uses materials such as cartons, long-term transportation can easily cause the air guide strip to press creases on the surface of the outer packaging. By using a placement board to support the goods, the chance of damage to the surface of the goods can be reduced, thereby improving the appearance of the goods.
[0017] Optionally, a placement rack is clamped on the air guide strip, the placement rack includes a base frame, a support rod and a top frame, one end of the support rod is fixed on the base frame, and the other end is fixed on the top frame, the air guide strip is provided with a mounting groove, and the base frame is clamped on the mounting groove.
[0018] By adopting the above technical solution, a placement rack is arranged on the air guide strip so that the bottom frame can be stuck in the installation groove of the air guide strip. When the refrigerated truck is driving, the length direction of the bottom frame is perpendicular to the forward direction of the vehicle, so that the bottom frame can be stably connected to the air guide strip, which is convenient for users to install and remove the placement rack on the air guide strip. The top frame can use a wire mesh structure with multiple through holes. When the top frame supports the goods, the bottom surface of the goods can exchange heat with the low-temperature air in the cargo compartment.
[0019] Optionally, the top frame is configured as a flat plate structure, and a plurality of through holes are provided on the flat plate.
[0020] By adopting the above technical solution and setting the top frame as a flat plate structure, the supporting capacity of the top frame for goods is further improved, which is suitable for supporting goods with higher density.
[0021] Optionally, a plurality of water passing grooves are formed in the chassis. The water passing grooves are formed in the lower bottom of the chassis. When the chassis is clamped in the installation groove, the gap between the water passing grooves and the adjacent air guiding strips is communicated.
[0022] By adopting the above technical solution, by forming water passing grooves in the chassis, when the chassis is clamped on the air guiding strips, the condensed water between the adjacent air guiding strips can flow through the water passing grooves, thereby reducing the probability of condensed water accumulating in the frame-shaped space formed by the air guiding strips and the chassis, and reducing the probability of the condensed water soaking the goods.
[0023] To sum up, the beneficial technical effects of the present application are as follows:
[0024] 1. By arranging a plurality of air guiding strips on the substrate, when the goods are placed on the substrate, the air guiding strips can support the goods, so that a gap is formed between the surface of the goods and the substrate. When the refrigeration unit of the cargo compartment works, the low-temperature air can flow in the gap between the adjacent air guiding strips, thereby increasing the contact area between the low-temperature air and the surface of the goods, enabling each surface of the goods to perform heat exchange with the low-temperature air, and thus enabling the goods to be evenly cooled in the cargo compartment;
[0025] 2. By making the length direction of the air guiding strips point to the opening of the cargo compartment, when condensed water is generated in the cargo compartment, the condensed water can flow on the surface of the substrate and flow into the gap between the air guiding strips, thereby reducing the probability of the condensed water contacting the bottom of the goods and reducing the probability of the condensed water soaking the bottom of the goods. The user can conveniently and quickly remove the condensed water from the gap between the air guiding strips outside the cargo compartment, which is convenient for the user to clean;
[0026] 3. By arranging a placing plate on the air guiding strip, the user can stack the goods on the placing plate. The placing plate is a flat plate and supports the goods. When the outer packaging of the goods uses materials such as cardboard boxes, long-term transportation is likely to cause the air guiding strip to press out creases on the surface of the outer packaging. By using the placing plate to support the goods, the probability of damage to the surface of the goods can be reduced, and the aesthetics of the goods can be improved. Description of the Drawings

[0033] The following further describes the present application in detail with reference to the drawings.
[0034] An embodiment of the present application discloses an air guiding structure for a refrigerated truck. Referring to Figure 1 and Figure 2 , it includes a substrate 1 and a plurality of air guide strips 2. The substrate 1 is fixed on the inner wall of the refrigerated truck compartment. The substrate 1 and the air guide strips 2 are made of metal plates. The air guide strips 2 are parallel to each other and arranged and welded on the substrate 1. The length direction of the air guide strips 2 faces the direction of the cargo compartment exit. The air guide strips 2 are perpendicular to the substrate 1. When the user places the goods in the substrate 1, the air guide strips 2 support the goods, forming a gap between the surface of the goods and the substrate 1. When the temperature in the cargo compartment decreases, the low-temperature air can flow into the gap between the air guide strips 2, so that the contact area between the low-temperature air and each surface of the goods is relatively large, and the goods can be evenly cooled in the cargo compartment, optimizing the problem that the temperature at the bottom of the goods is relatively high and difficult to cool. When condensate is generated in the cargo compartment due to low temperature, the condensate can accumulate in the gap between the air guide strips 2, thereby reducing the probability of the condensate wetting the goods and keeping the outer surface of the goods relatively dry.
[0035] Referring to Figure 3 , a groove 22 is formed in the air guide strip 2. The groove 22 is formed at the top of the air guide strip 2 and is a semi-circular groove. When the goods are placed on the air guide strip 2, the groove 22 is located at the bottom of the goods, so that the low-temperature air can flow to the bottom of the goods through the groove 22, further increasing the contact area between the goods and the low-temperature air.
[0036] Referring to Figure 3 , an inclined surface 23 is formed at the end of the air guide strip 2. The inclined surface 23 is formed on the side of the air guide strip 2 close to the opening of the cargo compartment. When the user transports the goods, the probability of the sharp corners of the air guide strip 2 scratching the outer packaging of the goods can be reduced.
[0037] Referring to Figure 2 , in other embodiments, a placing plate 4 is welded to the air guide strip 2. The placing plate 4 horizontally covers the air guide strip 2, and the size of the placing plate 4 is smaller than that of the substrate 1. A plurality of through holes are formed in the placing plate 4, and the through holes communicate with the gap between the air guide strips 2. The user can place the goods on the placing plate 4. When the texture of the outer packaging of the goods is relatively soft, using the placing plate 4 to support the goods can reduce the probability of the outer packaging being deformed and bent during the transportation of the goods.
[0038] Referring toFigure 3 and Figure 4 In other embodiments, a plurality of placement racks 3 are provided on the air guide strip 2. An installation groove 21 is formed in the air guide strip 2, and the length direction of the installation groove 21 is perpendicular to the length direction of the air guide strip 2. The placement rack 3 is snap-fitted into the installation groove 21. The placement rack 3 includes a plurality of bottom frames 31, a plurality of support rods 32 and a top frame 33. One end of the support rod 32 is fixed to the bottom frame 31, and the other end is fixed to the top frame 33. The bottom frame 31 is a plate-like structure, and the bottom frame 31 is inserted into the installation groove 21 of the air guide strip 2, so that the placement rack 3 can be fixed on the substrate 1. By placing the goods on the top frame 33, the goods are suspended above the substrate 1, which can reduce the probability of the air guide strip 2 pressing scratches on the surface of the goods during long-distance transportation.
[0039] Refer to Figure 4 , the top frame 33 can be made of wire mesh. In other embodiments, the top frame 33 can be set as an iron plate, and a plurality of through holes are formed in the iron plate. The low-temperature air exchanges heat with the bottom of the goods through the through holes.
[0040] Refer to Figure 5 , a plurality of water passing grooves 311 are formed in the bottom frame 31. The water passing grooves 311 are formed on the lower bottom side of the bottom frame 31. When the bottom frame 31 is snap-fitted on the air guide strip 2, the water passing grooves 311 communicate with the gaps between two adjacent air guide strips 2. When the placement rack 3 is arranged on the air guide strip 2, the condensed water between the air guide strips 2 can pass through the water passing grooves 311 and flow out, thereby reducing the accumulation degree of the condensed water in the cargo compartment.
[0041] The implementation principle of the embodiment of the present application is as follows: By installing the air guide strip 2 on the substrate 1, the low-temperature air in the cargo compartment can flow to the bottom of the goods through the gaps between the air guide strips 2, so that the low-temperature air can uniformly contact the outer surface of the goods and exchange heat, enabling the goods to be uniformly cooled and refrigerated. When condensed water is generated on the surface of the substrate 1, the condensed water can fall into the gaps between the air guide strips 2, thereby reducing the probability of the condensed water soaking the bottom of the goods and keeping the surface of the goods dry.
[0042] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
