Description

Technical Field

[0001] This utility model belongs to the field of refrigerated trucks, specifically a refrigerated truck cold air circulation system and a refrigerated truck. Background Technology

[0002] Refrigerated trucks are enclosed vans used to transport frozen or fresh goods. They are specialized refrigerated transport vehicles equipped with refrigeration units and polyurethane insulated compartments. They are commonly used to transport frozen foods (frozen food trucks), dairy products (dairy trucks), fruits and vegetables (fresh produce trucks), vaccines and medicines (vaccine trucks), etc.

[0003] Application No.: CN202510892388.9 provides a refrigerated truck compartment that facilitates loading and unloading of raw meat, thereby improving loading and unloading efficiency.

[0004] Application No.: CN202510698653.X provides a refrigerated truck for cold chain transportation. This refrigerated truck uses movable seats and movable partitions to divide the refrigeration space and storage space inside the refrigerated compartment. The size of the partition area can be adjusted by an adjustment mechanism, so that the refrigeration components can centrally refrigerate the goods in the refrigeration space, prevent the cold air from spreading throughout the refrigerated compartment, and reduce energy consumption.

[0005] Application No. CN202510524020.7 discloses a method, device, and storage medium for controlling temperature and humidity in refrigerated transportation, which solves the problem that refrigerated trucks cannot adjust according to actual temperature and humidity changes during transportation, resulting in poor preservation effect and improves the accuracy of temperature and humidity control in refrigerated transportation.

[0006] The aforementioned patent documents specify the temperature control and zoning of refrigerated trucks.

[0007] Application number CN202411682280.9 relates to a long-distance cold chain logistics transport box with preservation function. It guides and diverts cold air through a diversion pipe, allowing some of the cold air to be discharged into the middle of the storage cavity through a third air outlet. This patent document achieves a central placement of stacked preserved products, enabling the preserved products in the storage cavity to absorb cold air more evenly and improving the preservation effect.

[0008] The loading of cargo into the carriage can cause the cargo to stick together at the bottom, middle, and top, as well as at the front, middle, and rear of the carriage, making unloading difficult. Utility Model Content

[0009] In order to solve the problem of refrigerated goods sticking together in refrigerated trucks and to achieve the function of preservation in all aspects, this utility model provides a refrigerated truck cold air circulation system and a refrigerated truck.

[0010] For this reason, the technical solution of the present utility model is a cold air circulation system for a refrigerated truck, including a refrigerated truck body. A cold air system is provided at the upper part of the front panel. It is characterized in that: a layer of guiding sailcloth is suspended under the inner top plate of the refrigerated truck body. The guiding sailcloth hangs down and is arranged parallel to the inner top plate. The guiding sailcloth and the inner top plate form a through ventilation duct, and the through ventilation duct is connected to the outlet of the cold air system and diverts the cold air.

[0011] The effect is that: the through ventilation duct can introduce or divert the cold air of the cold air system to the tail of the refrigerated truck body through the through ventilation duct, so that the whole refrigerated truck body can obtain uniform cold air and achieve the refrigeration effect in the whole refrigerated truck body.

[0012] At the same time, the guiding sailcloth is suspended on the inner top plate, with light weight, no space occupation, and good plasticity and air guiding effect.

[0013] A further improvement is that: a plurality of air guiding windows are provided in the middle of the guiding sailcloth, and the air guiding windows form cold air channels in the refrigerated truck body.

[0014] The effect is that: the setting of a plurality of air guiding windows can evenly disperse the cold air of the through ventilation duct connected to the cold air system to the middle of the refrigerated truck body, so that the whole refrigerated truck body can evenly receive cold air and achieve the refrigeration effect.

[0015] A further improvement is that: a plurality of front panel air guiding grooves are vertically provided on the front panel plane of the refrigerated truck body; a plurality of rear panel air guiding grooves are vertically provided on the rear panel plane; a plurality of bottom panel air guiding grooves are longitudinally provided on the bottom panel; the front panel air guiding grooves, the rear panel air guiding grooves correspond to the through ventilation duct, and the bottom panel air guiding grooves correspond to the front panel air guiding grooves and the rear panel air guiding grooves to form a circulation system.

[0016] The effect is that: this circulation system makes the front panel air guiding grooves, the rear panel air guiding grooves, the bottom panel air guiding grooves and the through ventilation duct correspond to each other. At this time, the cold air of the cold air system will circulate in the whole refrigerated truck body, so as to achieve the refrigeration effect.

[0017] A further improvement is that: the front panel air guiding grooves and the rear panel air guiding grooves are in a "U" - shaped structure and are respectively fixed on the front panel plane and the rear panel plane.

[0018] The effect is that: the "U" - shaped structure forms a natural protrusion, which not only separates the refrigerated goods from the front panel plane and the rear panel plane without adhesion, but also can naturally form a ventilation channel. At this time, the inner channel formed by the interval between the "U" - shaped structure and the front panel plane and the rear panel plane forms a circulation, and the protrusion of the "U" - shaped structure and the goods paper form an outer channel, and the cold air from the outer channel takes into account the frozen goods.

[0019] A further improvement is that: the bottom panel air guiding grooves are in a corrugated structure, forming multiple channels.

[0020] It should be noted that in the translation of "几”状结构, it is translated as "U" - shaped structure here. If there is a more accurate specific shape name in the context, it can be adjusted accordingly.The effect is that the corrugated structure of the bottom plate air guide channel forms multiple channels that naturally protrude, which not only separates the refrigerated goods from the bottom plate to prevent them from sticking, but also naturally forms ventilation channels. At this time, the multiple channels forming natural protrusions and the inner channels formed by the bottom plate form a circulation, and the cold air from the outer channel also serves the frozen goods. Beneficial effects

[0021] This utility model has a simple structure and is economical and practical. It can achieve all-round refrigeration and transportation of goods inside the refrigerated compartment, preventing goods from sticking to the interior of the compartment and ensuring good preservation. Loading and unloading are also convenient and reliable. The system allows for efficient and even circulation of cold air throughout the compartment, and effectively guides and prevents cold air from escaping when the compartment doors are open, reducing power consumption.

Under the inner top panel 103, a layer of guiding sailcloth 3 is suspended. The guiding sailcloth 3 hangs down and is arranged relatively parallel to the inner top panel 103. The guiding sailcloth 2 and the inner top panel 103 form a through ventilation duct 301, and the through ventilation duct 301 is connected to the outlet of the cold air system 2 and divides the flow.

[0025] As Figure 2-4 shown.

[0026] A plurality of air guiding windows 4 are formed in the middle of the guiding sailcloth 3, and the air guiding windows 4 form cold air channels inside the refrigerated truck body 1.

[0027] As Figure 1 , 2 , 5, 6, 7 shown.

[0028] On the plane of the front panel 101 of the refrigerated truck body 1, a plurality of front panel air guiding grooves 6 are vertically provided; on the plane of the rear panel 102, a plurality of rear panel air guiding grooves 5 are vertically provided; on the bottom panel 104, a plurality of bottom panel air guiding grooves 7 are longitudinally provided; the front panel air guiding grooves 6, the rear panel air guiding grooves 5 correspond to the through ventilation duct 301, and the bottom panel air guiding grooves 7 correspond to the front panel air guiding grooves 6 and the rear panel air guiding grooves 5 to form a circulation system.

[0029] As Figure 6 , 7 shown.

[0030] The front panel air guiding grooves 6 and the rear panel air guiding grooves 5 are in a "U" - shaped structure and are respectively fixed on the plane of the front panel 101 and the plane of the rear panel 102.

[0031] As Figure 5 shown.

[0033] Working principle:

[0034] Among them Figure 1-2 The direction indicated by the arrow is the flow direction of the cold air.

[0035] The outlet of the cold air system 2 forms a through ventilation duct 301 with the guiding sailcloth 2 and the inner top panel 103 and divides the flow. At this time, the cold air also sends the cold air to the middle of the refrigerated truck body 1 through the multiple air guiding windows 4 of the guiding sailcloth 2. The cold air divided by the through ventilation duct 301 to the rear panel 102 flows downward through the rear panel air guiding grooves 5 and then is led to the bottom panel air guiding grooves 7, and the bottom panel air guiding grooves 7 lead it to the front panel air guiding grooves 6. At this time, a relative circulation system is formed; the excess cold air after the multiple air guiding windows 4 send the cold air to the middle of the refrigerated truck body 1 will also flow along the bottom panel air guiding grooves 7 and then be led to the external channels of the front panel air guiding grooves 6. At this time, a complete circulation system is formed.
