Technical Field

[0001] This utility model belongs to the field of refrigeration application technology, specifically relating to an easy-to-maintain refrigeration unit for refrigerated trucks. Background Technology

[0002] With the rapid development of the economy and society and the continuous improvement of people's living standards, the demand for cold chain logistics is becoming increasingly strong, and the market size for the transportation of chilled, refrigerated, and frozen foods is constantly expanding. Driven by market demand, the cold chain logistics industry has achieved rapid development.

[0003] Refrigerated trucks are enclosed vans used to transport frozen or fresh goods. They are refrigerated transport vehicles equipped with refrigeration units and polyurethane insulated compartments. They are commonly used to transport frozen foods (refrigerated trucks), dairy products (dairy trucks), fruits and vegetables (fresh goods trucks), vaccines and medicines (vaccine trucks), etc.

[0004] The refrigeration unit of a refrigerated truck mainly consists of a compressor, condenser, evaporator, and expansion valve. The working principle of the refrigeration unit is that it relies on external power to drive the compressor, causing the refrigerant to circulate continuously within the system. When the refrigerant flows through the evaporator, it absorbs heat from the compartment through evaporation, and then releases the heat through the condenser outside the compartment. This continuous cycle achieves a continuous cooling effect.

[0005] The refrigeration unit of the refrigerated truck is installed on the refrigerated box to regulate and control the temperature inside the refrigerated box. The current refrigeration units are usually installed close to the refrigerated box, which has the following problems: (1) It is inconvenient to install the refrigeration unit and the refrigeration box, thus prolonging the assembly time. In addition, the close-fitting installation (mounting) is insufficient in terms of heat dissipation, which affects its service life; (2) It is inconvenient to perform maintenance operations during later use.

[0006] Therefore, based on the above problems, this utility model provides an easy-to-maintain refrigeration unit for refrigerated trucks. Utility Model Content

[0020] Example 1 like Figure 1 , Figure 2 and 3 The refrigeration unit shown includes an easy-to-maintain refrigerated truck frame 100, a refrigerated box 200, and a refrigeration unit 300. A fixing plate 10 is welded to the upper outer wall of one end of the refrigerated box 200. A first horizontal connecting plate 11 is vertically arranged on one side of the fixing plate 10. A plurality of first horizontal connecting plate through slots 12 are respectively provided in the end face of one end of the first horizontal connecting plate 11. A second horizontal connecting plate 15 is vertically fixed on the refrigeration unit 300. A plurality of second horizontal connecting plate through slots 16 are respectively provided in the end face of one end of the second horizontal connecting plate 15. The first horizontal connecting plate 11 and the second horizontal connecting plate 15 are fixed together by bolts 13 and nuts 14 through the through grooves 12 and 16 of the first horizontal connecting plate.

[0021] The working principle or structural principle is as follows: First, the fixing plate 10 is welded to the upper outer wall of one end of the refrigerated box 200 (the height is based on not interfering with the connection between the vehicle towing head and the frame 100); then, the second horizontal connecting plate 15 is fixed (welded) to the refrigeration unit 300; finally, the second horizontal connecting plate 15 is pushed horizontally to the surface of the first horizontal connecting plate 11, and the first horizontal connecting plate through groove 12 and the second horizontal connecting plate through groove 16 are aligned. At this time, the first horizontal connecting plate 11 and the second horizontal connecting plate 15 are fixed by bolts 13 and nuts 14 through the first horizontal connecting plate through groove 12 and the second horizontal connecting plate through groove 16.

[0022] The above-mentioned assembly process is convenient, and the maintenance of the refrigeration unit 300 is also convenient (the suspended design provides a large operating space). The refrigeration unit 300 is also easy to disassemble; simply unscrew bolt 13 and nut 14.

[0023] In addition, the first horizontal connecting plate 11 and the second horizontal connecting plate 15 are preferably set as L-shaped structures of the same size; wherein, after assembly, the L-shaped surfaces of the first horizontal connecting plate 11 and the second horizontal connecting plate 15 are opposite each other, thus forming a mutual interlocking structure, which facilitates assembly and has a large load-bearing capacity.

[0024] Example 2 Based on Embodiment 1, the easy-to-maintain refrigeration unit for refrigerated trucks also includes a limiting groove 17 and a limiting protrusion 18 disposed on opposite sides of the first horizontal connecting plate 11 and the second horizontal connecting plate 15, with the limiting protrusion 18 embedded in the limiting groove 17; wherein the limiting groove 17 and the limiting protrusion 18 are configured as matching circular structures.

[0025] In the above, the limiting groove 17 and the limiting protrusion 18 play a positioning role during assembly, which facilitates the quick locking and fixing of bolts 13 and nuts 14; after assembly, they also play a certain role in reducing horizontal swaying during use.

[0026] In addition, the first horizontal connecting plate through groove 12 and the second horizontal connecting plate through groove 16 are preferably set as circular structures, which are used to match the bolts 13 and nuts 14 to complete rapid assembly.

[0027] Furthermore, preferably, the fixing plate 10, the first horizontal connecting plate 11, the plurality of first horizontal connecting plate through grooves 12 and the limiting groove 17 are integrally formed alloy steel; wherein, the thickness of the first horizontal connecting plate 11 is 4-10mm. The integrally formed alloy steel mentioned above has strong load-bearing capacity (able to withstand large loads), and at the same time has excellent chemical properties and is durable (high hardness and wear resistance), ensuring the stability of the refrigerated box 200 and the refrigeration unit 300 after assembly.

[0028] In addition, preferably the second horizontal connecting plate 15, several second horizontal connecting plate through slots 16 and limiting protrusions 18 are integrally formed alloy steel; wherein, the thickness of the second horizontal connecting plate (15) is 4-10mm; the integrally formed alloy steel has strong load-bearing capacity (bears large loads), and at the same time has excellent chemical properties and is durable (high hardness and wear-resistant), ensuring the stability of the refrigerated box 200 and the refrigeration unit 300 after assembly.

[0029] Furthermore, preferably as follows Figure 4The first horizontal connecting plate through groove 12 and the second horizontal connecting plate through groove 16 shown are respectively set as waist-shaped structures. In this way, during the assembly process, the distance between the fixing plate 10 and the refrigeration unit 300 can be adjusted by controlling the horizontal relative position of the first horizontal connecting plate 11 and the second horizontal connecting plate 15, so as to achieve the function of horizontal fine adjustment during assembly (this design structure has no limit groove 17 and limit protrusion 18).

[0030] The refrigeration unit of this easy-to-maintain refrigerated truck, including the frame 100, refrigerated box 200, and refrigeration unit 300, consists of conventional components, devices, or equipment. These are readily apparent to those skilled in the art without any inventive effort, and therefore the applicant will not elaborate further.
