Description

Technical Field

[0001] This utility model relates to the field of refrigerated truck technology, and in particular to a highly enclosed refrigerated truck. Background Technology

[0002] Refrigerated trucks are specialized containers used for transporting or storing goods requiring temperature control, widely used in temperature-sensitive fields such as food, pharmaceuticals, and chemicals. The airtightness of a refrigerated truck directly determines its insulation and energy-saving capabilities. High sealing performance reduces cooling flow, maintaining low temperatures for extended periods. High airtightness also allows for even lower refrigeration temperatures, ensuring ultra-low temperature requirements for special cargo containers. Existing refrigerated truck structures primarily achieve sealing through locking mechanisms. However, continuous door opening during loading and unloading causes significant cold air loss, leading to temperature increases. Subsequent warming processes consume substantial amounts of electricity, increasing operating costs. Furthermore, ordinary locking mechanisms cannot apply sustained pressure to the door, resulting in gaps and reduced sealing. Therefore, this invention addresses these issues by improving existing equipment. Utility Model Content

The cooling components include a dustproof plate 6, which is installed and fixed on one side of the rear end of the top surface of the top plate 4. A refrigeration unit 8 is installed and fixed below the dustproof plate 6 on the top surface of the partition 7. An air inlet pipe 9 is connected to one side of the refrigeration unit 8.

Through the cooperation of the refrigeration unit 8 and the exhaust fan 11, the air in the box can be quickly replaced for cooling, which improves the cooling efficiency.

[0020] In this utility model, in order to solve the problem of low sealing performance and easy heat loss in the closed structure of existing equipment, the following technical solution is adopted: The heat insulation component includes a shelf 12, which is installed and fixed on the top surface of the bottom plate 1. A heat insulation layer 13 is provided between the opposite surfaces of the side plate 2 and the back plate 3. A strength strip 14 is provided on the heat insulation layer 13. The installation component includes a roller shutter 15, which is installed and fixed on the front end of the bottom of the partition 7 by a pressure plate 22. The pressure plate 22 is fixed to both sides of the front end of the bottom of the partition 7 by fastening screws 23. The clamping assembly includes a rotating frame 16. One end of the rotating frame 16 is fixedly mounted on the upper and lower sides of the front end of the side plate 2.

[0021] Working principle: When using this utility model, first power is supplied to all electrical equipment, then the refrigeration unit 8 is started, which draws in and cools the air before it enters the box through the air inlet pipe 9. At the same time, the exhaust fan 11 continuously draws out air through the exhaust pipe 10 to ensure rapid cooling inside the box. Then the box door 5 is opened, allowing it to rotate around the rotating frame 16 while the hydraulic rod 20 extends. Then the goods are loaded. During loading, the roller shutter 15 can ensure that the cold air does not escape quickly to a certain extent, ensuring that the temperature inside the box is stable. After loading is completed, the box door 5 is closed, and then oil is supplied to the hydraulic rod 20, causing the hydraulic rod 20 to continuously contract, thereby continuously pressing the box door 5 to prevent gaps from forming due to vehicle movement, thus ensuring temperature stability. When the box needs to be cleaned, the roller shutter 15 can be removed by turning the fastening screw 23 to loosen the pressure plate 22. After cleaning, the above work is repeated to reinstall the roller shutter 15.
