[0055] To address the problem in related technologies where rigidly connected media pipelines are prone to breakage or leakage due to vibration or deformation of the refrigeration unit, this application provides a refrigeration compartment. See also... Figures 1 to 5 The refrigerated compartment includes a compartment body 1, a refrigeration unit 2, and a media pipeline system 3.

[0056] The refrigeration unit 2 is installed inside the cabin 1. The media piping system 3 is connected to the cabin 1 and communicates with the refrigeration unit 2. The media piping system 3 is configured to transport the cooling medium to be cooled to the refrigeration unit 2 and to transport the cooled medium, after being cooled by the refrigeration unit 2, to the heat-generating equipment requiring cooling. The media piping system 3 includes a rigid pipe section 3a and a flexible pipe section 3b connected to and communicating with the rigid pipe section 3a. The flexible pipe section 3b can also be referred to as a flexible pipe section or a hose section.

[0057] In this embodiment, the media piping system 3 includes a rigid pipe section 3a and a flexible pipe section 3b connected and communicating with the rigid pipe section 3a. The flexible pipe section 3b can bend and deform to adapt to the vibration of the refrigerated vehicle or the deformation of the refrigeration compartment under external forces, so as to effectively absorb vibration or deformation. Therefore, it improves the problem of media piping breakage or leakage caused by the vibration or deformation of the refrigerated vehicle in related technologies. Even when the refrigerated vehicle is traveling under complex road conditions, the flexible pipe section 3b can effectively prevent vibration from being transmitted to the rigid pipe section 3a, so as to prevent media piping breakage or leakage.

[0058] The refrigeration compartment includes multiple refrigeration units 2 arranged along the first direction. The medium piping system 3 includes a main pipe 31 extending along the first direction and multiple branch pipes 32 that respectively connect the multiple refrigeration units 2 and the main pipe 31. The regular piping layout in the refrigeration compartment is conducive to improving the space utilization of the refrigeration compartment and also conducive to reducing the weight of the refrigeration compartment by simplifying the piping.

[0059] The rigid pipe segment 3a includes a first rigid pipe segment 31a that forms part of the main pipeline 31, and the flexible pipe segment 3b includes a first flexible pipe segment 31b that forms part of the main pipeline 31. The first rigid pipe segment 31a and the first flexible pipe segment 31b are connected and communicate with each other. That is, the main pipeline 31 includes the first rigid pipe segment 31a and the first flexible pipe segment 31b.

[0060] The rigid pipe segment 3a includes a second rigid pipe segment 32a that forms part of the branch pipe 32, and the flexible pipe segment 3b includes a second flexible pipe segment 32b that forms part of the branch pipe 32. The second rigid pipe segment 32a and the second flexible pipe segment 32b are connected and communicate with each other. That is, the branch pipe 32 includes a second rigid pipe segment 32a and a second flexible pipe segment 32b.

[0061] Each refrigeration unit is connected to and communicates with the main pipe 31 through a branch pipe 32. The main pipe 31 includes a first flexible pipe section 31b, and the branch pipe 32 includes a second flexible pipe section 32b. The first flexible pipe section 31b can adapt to the vibration or deformation of the refrigeration vehicle and deform accordingly along the radial direction of the first flexible pipe section 31b perpendicular to the first direction mentioned above to absorb vibration and deformation. The second flexible pipe section 32b can adapt to the vibration or deformation of the refrigeration vehicle and deform accordingly along the radial direction of the second flexible pipe section 32b to absorb vibration and deformation.

[0062] In some embodiments, the axial direction of the second flexible tube segment 32b intersects the axial direction of the first flexible tube segment 31b. The first flexible tube segment 31b can deform accordingly in the radial direction to absorb vibrations or deformations of the refrigerated vehicle. The second flexible tube segment 32b can also deform accordingly in the radial direction to absorb vibrations or deformations of the refrigerated vehicle. Since the axial directions of the first flexible tube segment 31b and the second flexible tube segment 32b intersect, the first flexible tube segment 31b and the second flexible tube segment 32b can cooperate to absorb vibrations in any direction and deform accordingly to absorb vibrations or deformations in any direction.

[0063] The main pipe 31 includes a branch pipe 311 and a manifold 312. The branch pipe 311 is connected to and communicates with multiple refrigeration units 2 through branch pipes 32, and is configured to deliver cooling medium to be cooled to the multiple refrigeration units 2. The manifold 312 is connected to and communicates with multiple refrigeration units 2 through branch pipes 32, and is configured to deliver the cooling medium cooled by the refrigeration units 2 to the heat-generating equipment.

[0064] The distribution pipe 311 includes a first rigid pipe section 31a and a first flexible pipe section 31b. The manifold 312 also includes a first rigid pipe section 31a and a first flexible pipe section 31b. Multiple refrigeration units 2 are connected to the distribution pipe 311 via branch pipes 32 to introduce cooling media to be cooled. The multiple refrigeration units 2 are also connected to the manifold 312 via branch pipes 32 to deliver the cooled cooling media to the manifold 312. The manifold 312 collects the cooled media from the multiple refrigeration units 2 and delivers it to the heat-generating equipment for cooling.

[0065] Both the branch pipe 311 and the manifold 312 extend along the first direction mentioned above. Multiple refrigeration units 2 are arranged along the first direction so that they can be connected to the branch pipe 32 and the branch pipe 311 and the manifold 312, which helps to simplify the piping in the refrigeration compartment and improve the space utilization of the refrigeration compartment.

[0066] See Figure 2 , 3 and Figure 5 The medium piping system 3 includes a pump 35 that supplies cooling medium to multiple refrigeration units 2, and an inlet pipe 33 connected to and communicating with the inlet of the pump 35 to supply the cooling medium to the pump 35. The outlet of the pump 35 is connected to a branch pipe 311.

[0067] The rigid pipe section 3a includes a third rigid pipe section 33a that forms part of the input pipe 33, and the flexible pipe section 3b includes a third flexible pipe section 33b that forms part of the input pipe 33. The third flexible pipe section 33b and the third rigid pipe section 33a are connected and communicate with each other. That is, the input pipe 33 includes the third rigid pipe section 33a and the third flexible pipe section 33b. A first control valve 33c is also provided in the input pipe 33. The third flexible pipe section 33b helps to reduce the transmission of vibrations generated by the pump 35 during operation, thereby reducing the probability of pipe breakage or leakage connected to the pump 35.

[0068] In some embodiments, the main pipe 31 further includes a return pipe 313 for introducing the cooling medium after cooling the heat-generating equipment. The return pipe 313 is connected and communicates with the input pipe 33. A third flexible pipe section 33b is connected between the return pipe 313 and the pump 35 to reduce the transmission of vibration generated by the pump 35 during operation to the return pipe 313, thereby reducing the probability of the return pipe 313 breaking or leaking.

[0069] The media piping system 3 also includes an output pipe 34 connected to and communicating with the outlet of the pump 35, and the output pipe 34 is connected to and communicating with the branch pipe 311.

[0070] The rigid pipe section 3a includes a fourth rigid pipe section 34a that forms part of the output pipe 34, and the flexible pipe section 3b includes a fourth flexible pipe section 34b that forms part of the output pipe 34. The fourth flexible pipe section 34b and the fourth rigid pipe section 34a are connected and communicate with each other. That is, the output pipe 34 includes the fourth flexible pipe section 34b and the fourth rigid pipe section 34a. A second control valve 34c and a one-way valve 34d are provided in the output pipe 34.

[0071] The inlet and outlet of pump 35 are connected to the rigid pipe section through the third flexible pipe section 33b and the fourth flexible pipe section 34b, respectively. This can reduce the transmission of pump 35 vibration to the rigid pipe section and also prevent the deformation of the refrigeration vehicle from causing the pump 35 to be fixed during installation.

[0072] See Figure 2 and Figure 3 The media piping system 3 also includes a wound tube assembly 37 and a connecting tube 36. See also Figure 8 The winding tube assembly 37 includes a bracket 371, a reel 372 rotatably mounted on the bracket 371, a hose 373 wound on the reel 372, and an interface component 374 mounted on the bracket 371, the interface component 374 being connected and communicating with the hose 373.

[0073] See Figure 3 One end of the connecting pipe 36 is connected to and communicates with the main pipe 31, and is configured to transport the cooling medium to be cooled to the refrigeration unit 2 or to transport the cooling medium cooled by the refrigeration unit 2 to the heat-generating equipment that needs to be cooled. The rigid pipe section 3a includes a fifth rigid pipe section 36a that forms part of the connecting pipe 36, and the flexible pipe section 3b includes a fifth flexible pipe section 36b that forms part of the connecting pipe 36. The fifth flexible pipe section 36b and the fifth rigid pipe section 3a are connected and communicate with each other. The fifth flexible pipe section 36b helps to reduce the transmission of vibrations from outside the refrigeration chamber to the inside of the refrigeration chamber through the return pipe 313, thereby protecting the medium pipeline inside the refrigeration chamber.

[0074] The winding tube assembly 37 also includes a drive 376 for rotating the reel 372 to wind or unwind the hose 373 on the reel 372 and a quick-connect fitting 375 connected to the hose 373.

[0075] The medium piping system 3 of this embodiment includes two wound tube assemblies 37. The hose 373 of one wound tube assembly 37 is connected to the manifold 312 through the interface component 374 and the connecting pipe 36 to transport the cooling medium after being cooled by the refrigeration unit 2 to the heat-generating equipment. The hose 373 of the other wound tube assembly 37 is connected to the return pipe 313 through the interface component 374 and the connecting pipe 36 to transport the cooling medium after being cooled by the heat-generating equipment to multiple refrigeration units 2 through the pump 35 and the branch pipe 311.

[0076] After the refrigeration vehicle arrives at the heat-generating equipment, it releases the hose of the coiled tube assembly 37 connected to the manifold 312 and connects the hose 373 to the cooling medium inlet of the heat-generating equipment via a quick-connect fitting 375; it also releases the hose 373 of the coiled tube assembly 37 connected to the return pipe 313 and connects the hose 373 to the cooling medium outlet of the heat-generating equipment via a quick-connect fitting 375. After the refrigeration compartment is started, the pump 35 pumps the high-temperature cooling medium returning from the heat-generating equipment out of the return pipe 313 and distributes it evenly to each refrigeration unit 2 via the branch pipe 311 and each branch pipe 32. The high-temperature cooling medium is cooled within the refrigeration unit 2 and then output through the manifold 312, returning to the heat-generating equipment via the coiled tube assembly 37 to complete the circulation of the cooling medium.

[0077] To meet the different cooling needs of the heat-generating equipment, the refrigeration unit 2 is configured to provide two cooling media at different temperatures. Specifically, the refrigeration unit 2 includes a compressor that compresses the refrigerant, a condenser connected to the compressor, a throttling valve connected to the condenser, an evaporator connected to the throttling valve, and a fan that provides cooling air to the condenser.

[0078] The refrigeration unit also includes a first radiator that exchanges heat with the evaporator, a second radiator configured to exchange heat with a fan, a first inlet connected to the first radiator, a second inlet connected to the second radiator, a first outlet connected to the first radiator, and a second outlet connected to the second radiator.

[0079] When the cooling medium flows through the first inlet, the first radiator, and the first outlet, it exchanges heat with the refrigerant in the evaporator. When the cooling medium flows through the second inlet, the second radiator, and the second outlet, it exchanges heat with the air supplied by the fan.

[0080] The media piping system 3 includes two parallel branch pipes 311. The first inlet and second inlet of the refrigeration unit 2 are respectively connected to the two branch pipes 311. The first outlet and second outlet of the refrigeration unit 2 are both connected to the manifold 312. A third control valve 314 is installed in each of the two branch pipes 311. When the cooling medium is selected to achieve cooling through heat exchange with the evaporator, the third control valve 314 in the branch pipe 311 connected to the second inlet of the refrigeration unit 2 is closed. When the cooling medium is selected to achieve cooling through heat exchange with air provided by a fan, the third control valve in the branch pipe 311 connected to the first inlet of the refrigeration unit 2 is closed.

[0081] See Figure 1 and 4The cabin 1 is equipped with two rows of refrigeration units 2. Each row of refrigeration units 2 includes multiple refrigeration units 2 arranged along the first direction. A maintenance passage is formed between the two rows of refrigeration units 2. This is to ensure that a certain number of refrigeration units 2 are installed, so as to set up a maintenance passage that is convenient for the maintenance of each refrigeration unit 2, thereby improving the space utilization of the refrigeration cabin.

[0082] The main pipe 3 is set between the two rows of refrigeration units 2 so that it can be connected to the refrigeration units 2 located on both sides of it through the branch pipe 32, which helps to simplify the piping and improve space utilization.

[0083] The diversion pipe 311 is located at the bottom of the compartment 1; the return pipe 313 is located at the top of the compartment 1. A maintenance passage can be formed between the diversion pipe 311 and the return pipe 313 to improve the utilization rate of the space inside the compartment and facilitate the maintenance of the equipment inside the compartment 1.

[0084] See Figure 6 The cabin 1 includes a frame structure and an outer shell covering the frame structure. A first rigid pipe section 31a is fixedly connected to the frame structure, and a first flexible pipe section 31b is connected to the first rigid pipe section 31a. The first rigid pipe section 31a is connected to the cabin 1 through a first connector 6.

[0085] See Figure 7 The second rigid pipe section 32a is fixedly connected to the frame structure, and the second flexible pipe section 32b is connected to the second rigid pipe section 32a. The rigid pipe section is connected to the frame structure of the cabin 1, and the flexible pipe section 3b absorbs the vibration and deformation transmitted from the cabin 1 to the rigid pipe section, which helps to reduce the probability of the branch pipe 32 and the main pipe connected to it breaking or leaking due to vibration.

[0086] See Figure 7 The two ends of the second rigid tube section 32a are respectively connected to the second flexible tube sections 32b. The vibration and deformation transmitted from the cabin 1 to the second rigid tube section 32a can be effectively absorbed by the second flexible tube sections 32b at both ends of the rigid tube section.

[0087] A second flexible pipe section 32b is provided at each end of the vertical branch pipe 32 between the refrigeration unit 2 and the main pipe 31, and a second rigid pipe section 32a is located between the two second flexible pipe sections 32b. The branch pipe 32 also includes a first flange 322 and a second flange 323, which are respectively connected to the ends of the two second flexible pipe sections 32b away from the second rigid pipe section 32a. One of the first flange 322 and the second flange 323 is connected to the refrigeration unit 2, and the other is connected to the main pipe 31. The second rigid pipe section 32a is installed inside the cabin 1 through a second connector 5.

[0088] In some embodiments, the cabin 1 is provided with two rows of refrigeration units 2, each row of refrigeration units 2 including a plurality of refrigeration units 2 arranged along a first direction, and a maintenance passage is formed between the two rows of refrigeration units 2.

[0089] The first direction mentioned above is the length direction of the refrigerated vehicle, which is perpendicular to the width direction. The two rows of refrigeration units 2 are located at both ends of the compartment 1 along the width direction of the refrigerated vehicle.

[0090] Pump 35 is located at one end of the compartment 1 along the first direction, and winding tube assembly 37 is located at the other end of the compartment 1 along the first direction. Manifold 312, return pipe 313, and branch pipe 311 are located between the two rows of refrigeration units. Branch pipe 311 is located at the bottom of compartment 1, and manifold 312 and return pipe 313 are located at the top of compartment 1.

[0091] In some embodiments, the flexible section 3b includes a braided hose.

[0092] Since Y = 2R(1-cosθ), the length L of the flexible pipe segment 3b is L = πRθ / 90 + KD. Therefore, the length L of the flexible pipe segment 3b is L = πRθ / 90 + KD, where θ = arccos(1-Y / (2R)).

[0093] π is the mathematical constant pi.

[0094] R is the minimum bending radius of the flexible tube segment 3b;

[0095] K is a constant, and is greater than or equal to 1 and less than or equal to 1.5;

[0096] Y represents the radial offset required for flexible pipe segment 3b.

[0097] According to another aspect of this application, a refrigerated vehicle is also provided, which includes the aforementioned refrigerated compartment and a frame that carries the refrigerated compartment. The frame can be a semi-trailer frame.

[0098] Specifically, in the technical solution of this application, by optimizing the internal structural layout of the cabin 1 and adding a flexible pipe section 3b to the rigid pipe section 3a, the overall vibration resistance of the refrigeration cabin is significantly improved. The refrigeration cabin of this embodiment not only effectively enhances the operational reliability of the refrigeration vehicle under different vehicle operating conditions, but also helps to improve the stability and durability of the refrigeration vehicle in complex environments, thereby meeting the performance requirements of the refrigeration cabin in the diverse application needs under complex road conditions.

[0099] The medium pipeline system 3 in this embodiment can meet the requirements of withstanding vibration loads and deformations in three directions (length direction, width direction and vertical direction of the refrigeration vehicle), which is conducive to ensuring the reliability of the refrigeration unit 2 and the medium pipeline system 3 inside the cabin 1, and balances the strength of the pipeline structure with the ability to absorb deformation and vibration.

[0100] Flexible pipe sections 3b are provided at both the inlet and outlet of pump 35, which reduces the vibration transmission between pump 35 and rigid pipe section 3a, prevents the components on the medium pipeline from failing due to vibration, and improves the reliability and stability of the refrigeration chamber.

[0101] This ensures that the internal structure of the cabin 1 has a high capacity to absorb vibration and deformation at both ends of the vertical direction, thereby improving the structural stability and airtightness of the flange connection in the medium pipeline and avoiding cracking and leakage caused by the pipeline being subjected to three-way vibration loads.

[0102] The refrigeration units 2 inside the refrigeration compartment are arranged on both sides of the compartment 1, with a maintenance passage reserved in the middle. The top of the passage is equipped with a return pipe 313 and a manifold pipe 312, and the bottom is equipped with a branch pipe 311. The branch pipes 32 of the refrigeration units are laid along both sides of the refrigeration units 2. The pipes are laid horizontally and vertically to ensure that there is maintenance space in the middle of the semi-trailer.

[0103] The technical solution of this embodiment achieves the following technical effects:

[0104] 1. Significantly improved vibration resistance of the refrigeration compartment, enhancing the reliability of its operation. By optimizing the internal structural layout of compartment 1 and adding flexible pipe sections to the rigid pipe sections, the problem of pipe pulling caused by vibration of the refrigerated truck under complex road conditions was effectively alleviated. This solved the problem of pipe cracking and leakage that is prone to occur in traditional rigid connection medium pipes, significantly improving the vibration resistance and operational reliability of the medium pipes in the refrigeration compartment.

[0105] 2. Balancing space utilization and lightweight structure to enhance overall durability and adaptability: This design achieves high-strength and high-durability vibration reduction and noise reduction while ensuring the internal space occupancy and weight requirements of the refrigeration chamber. This enables the refrigeration chamber to have better stability and long-term performance in complex environments and diverse application scenarios.

[0106] The above are merely exemplary embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
