[0054] like Figures 1 to 10 As shown in some embodiments of this application, a vehicle-mounted cooling compartment for supporting a refrigeration module 80 includes: a bottom support frame layer 10, a middle support frame layer 20, a top support frame layer 30, and an interlayer connection structure 40. The middle support frame layers 20 are spaced above the bottom support frame layer 10 and support the refrigeration module 80. The top support frame layers 30 are spaced above the middle support frame layers 20 and provide air outlet ducts for the refrigeration module 80. The interlayer connection structure 40 is fixedly connected to the bottom support frame layer 10, the middle support frame layer 20, and the top support frame layer 30.

[0055] The vehicle-mounted cooling compartment provided in this embodiment includes three support frame layers arranged sequentially from bottom to top: a bottom support frame layer 10, a middle support frame layer 20, and a top support frame layer 30. These three support frame layers are fixedly connected together by an interlayer connection structure. This arrangement of the three support frame layers and the interlayer connection structure improves the structural strength and rigidity of the vehicle-mounted cooling compartment, thereby enhancing its stability and durability and better meeting the performance requirements for withstanding vibration loads in multiple directions. Furthermore, the middle support frame layer 20 supports the cooling module 80, and other vehicle equipment can be arranged within the space between the middle support frame layer 20 and the bottom support frame layer 10. This improves the integration of the vehicle-mounted cooling compartment, fully utilizes its load-bearing capacity, and reduces the space occupied by the vehicle's own equipment.

[0056] In some embodiments, such as Figure 1 and Figure 2 As shown, at least one of the bottom support frame layer 10, the middle support frame layer 20 and the top support frame layer 30 is formed by welding profiles; and / or the interlayer connection structure 40 is fixedly connected to the bottom support frame layer 10, the middle support frame layer 20 and the top support frame layer 30 by welding.

[0057] The bottom support frame layer 10 and / or the intermediate support frame layer 20 and / or the top support frame layer 30 are formed by welding profiles, which improves the structural strength and stability of the respective support frame layers and the overall strength and stability of the vehicle-mounted cooling compartment, thus enhancing its vibration resistance. The interlayer connection structure 40, which welds and fixes the bottom support frame layer 10, intermediate support frame layer 20, and top support frame layer 30, further improves the overall structural strength and rigidity of the vehicle-mounted cooling compartment, thereby enhancing its stability and durability and better meeting the performance requirements of the vehicle-mounted cooling compartment in withstanding vibration loads from the first direction X, the second direction Y, and the third direction Z. Furthermore, compared to bolted connections, welding reduces the use of bolts, reducing the overall weight of the vehicle-mounted cooling compartment and preventing bolt loosening under vibration loads, thus ensuring stable operation of the vehicle-mounted cooling compartment under complex road conditions.

[0058] In some embodiments, such as Figure 1 and Figure 2 As shown, the bottom support frame layer 10, the middle support frame layer 20, the top support frame layer 30, and the interlayer connection structure 40 constitute a cuboid main structure with the surfaces containing the first direction X and the second direction Y perpendicular to the first direction X as the bottom surface and the third direction Z perpendicular to the bottom surface as the height direction. Specifically, the bottom support frame layer 10 includes a bottom square frame and a bottom inner support frame. The bottom square frame includes two transverse bottom main beams 11 extending along the first direction X and two longitudinal bottom main beams 12 extending along the second direction Y. The bottom inner support frame is fixedly connected within the bottom square frame. And / or the middle support frame layer 20 includes two transverse middle main beams 21 extending along the first direction X and spaced apart along the second direction Y, and a middle inner support frame fixedly connecting the two transverse middle main beams 21. And / or the top support frame layer 30 includes a top square frame and a top inner support frame. The top square frame includes two transverse top main beams 31 extending along the first direction X and two longitudinal top main beams 31 extending along the second direction Y. The main beam 32 is fixedly connected to the top inner support frame within the top square frame; and / or the interlayer connection structure 40 includes four main support columns 401 extending along the third direction Z perpendicular to the bottom support frame layer 10 and the top support frame layer 30, and multiple interlayer inner support frames located on different sides of the cuboid main structure. The four main support columns 401 are fixedly connected to the four corners of the bottom support frame layer 10 and the top support frame layer 30, respectively. Each interlayer inner support frame is fixedly connected to the area enclosed by the two main support columns 401, the bottom support frame layer 10, and the top support frame layer 30 on the same side. The intermediate support frame layer 20 is fixedly connected to at least some of the main support columns 401 and / or at least some of the interlayer inner support frames.

[0059] The bottom support frame layer 10 includes a bottom square frame and a bottom inner support frame, and / or the middle support frame layer 20 includes two transverse middle main beams 21 and a middle inner support frame, and / or the top support frame layer 30 includes a top square frame and a top inner support frame, which can improve the structural strength and stability of the corresponding support frame layer itself, and also benefit the overall strength and stability of the vehicle-mounted cooling compartment.

[0060] The interlayer connection structure 40 includes four main supporting columns 401 and multiple interlayer internal support frames located on different sides of the cuboid main structure. On the one hand, it enables the interlayer connection structure 40 to establish a stable cuboid main structure with the bottom support frame layer 10, the middle support frame layer 20 and the top support frame layer 30. On the other hand, the interlayer internal support frames and the main supporting columns 401 on both sides can enhance the structural strength and stiffness of the corresponding sides of the cuboid main structure, thereby enhancing the overall firmness and stability of the cuboid main structure, and thus improving the overall vibration resistance of the vehicle-mounted cooling compartment.

[0061] In some embodiments, such as Figures 1 to 8 As shown, the interlayer connection structure 40 also includes side reinforcement structures and / or corner reinforcement structures. The side reinforcement structures are configured to strengthen the side strength of the vehicle-mounted cooling compartment. The corner reinforcement structures are configured to strengthen the corner strength of the vehicle-mounted cooling compartment.

[0062] The addition of side reinforcement structures increases the structural strength and stiffness of the corresponding sides of the cuboid main structure containing the side reinforcement structures, thereby further improving the overall stability of the vehicle-mounted cooling compartment structure. Similarly, the addition of corner reinforcement structures increases the structural strength and stiffness of the corresponding corners of the cuboid main structure containing the corner reinforcement structures, thereby further improving the overall stability of the vehicle-mounted cooling compartment structure.

[0063] In some embodiments, such as Figures 1 to 8 As shown, at least one side reinforcement structure is fixedly connected between the supporting main column 401 and the bottom square frame; and / or as shown in the figure. Figures 1 to 7 As shown, at least one side reinforcement structure is fixedly connected between the supporting main column 401 and the top square frame; and / or as shown in the figure. Figures 1 to 4 and Figure 7 As shown, at least one side reinforcement structure is fixedly connected between the main supporting column 401 and the inter-story support frame; and / or as shown in the diagram. Figures 1 to 4 and Figure 7 As shown, at least one side reinforcement structure is fixedly connected between the interlayer support frame and the bottom square frame; and / or as shown in the diagram. Figures 5 to 7 As shown, at least one side reinforcement structure is fixedly connected between the interlayer support frame and the top square frame; and / or as shown in the diagram. Figures 1 to 8As shown, at least one corner reinforcement structure is a bottom corner reinforcement structure disposed at the bottom corner of the cuboid main structure; and / or as shown in the figure. Figures 1 to 7 As shown, at least one corner reinforcement structure is a corner reinforcement structure set at the top corner of the cuboid main structure.

[0064] Side reinforcement structures help improve the load-bearing capacity of connected components and reduce the deformation of the sides of the cuboid main structure where the side reinforcement structure is located. In addition, side reinforcement structures help suppress torsional deformation at the connection nodes of beams and columns forming the cuboid main structure caused by asymmetrical loads or uneven local stress, maintain geometric stability, and thus further improve the overall stability of the vehicle-mounted cooling compartment structure.

[0065] Vehicle-mounted cooling compartments are often subjected to loads in three directions during vehicle operation. The bottom and top corners of the rectangular main structure are prone to stress concentration points. Bottom and top corner reinforcement structures are respectively set at the bottom and top corners of the rectangular main structure to increase the structural strength and stiffness of the bottom and top corners of the rectangular main structure where the bottom and top corner reinforcement structures are located, thereby further improving the overall stability of the vehicle-mounted cooling compartment structure.

[0066] In some embodiments, such as Figures 1 to 7 As shown, at least one side reinforcement structure includes a side diagonal bracing rod 4071, and at least one supporting main column 401 and at least one of the bottom square frame, top square frame and inter-story support frame connected thereto are fixedly connected to the side diagonal bracing rod 4071; and / or as shown Figure 3 and Figure 4 As shown, at least one side reinforcement structure includes a side diagonal bracing rod 4071, and at least one inter-story support frame and at least one of the bottom square frame and top square frame connected thereto are fixedly connected to the side diagonal bracing rod 4071; and / or as shown in the figure. Figures 5 to 7 As shown, at least one interlayer support frame has a side diagonal bracing rod 4071 fixedly connected between different components; and / or as shown in the diagram. Figures 1 to 8 As shown, at least one side reinforcement structure includes a triangular plate 4072, and at least one supporting main column 401 and at least one of the bottom square frame, top square frame and inter-story support frame connected thereto are fixedly connected to the triangular plate 4072; and / or as shown in the figure. Figure 8 As shown, at least one bottom corner reinforcement structure includes a fixing corner piece 407a, which surrounds and fixes a support main column 401 to the connection point of its connected bottom support frame layer 10; and / or as shown in the figure. Figure 7As shown, at least one apex corner reinforcement structure includes a protective triangular structure 407b, which surrounds and is fixedly connected to a supporting main column 401 and the connection point of the component of the vehicle-mounted cooling compartment connected to the supporting main column 401 at the corresponding apex corner.

[0067] By setting the side diagonal support rod 4071, the connection stability between the connected structures can be improved, which is conducive to improving the load-bearing capacity of the connected components, reducing the deformation of the side of the cuboid main structure where the side support rod is located, and maintaining the geometric stability of the cuboid main structure, thereby further improving the overall stability of the vehicle cooling compartment structure.

[0068] Setting up the triangular plate 4072 allows for targeted reinforcement at specific locations, which helps improve the lateral stiffness of the cuboid main structure where the connected structure is located. This also helps improve the connection stability of the connected structure, thereby enhancing the load-bearing capacity of the connected components. It also reduces the deformation of the lateral side of the cuboid main structure where the triangular plate 4072 is located, helping to maintain the geometric stability of the cuboid main structure. Ultimately, this further improves the overall stability and vibration resistance of the vehicle-mounted cooling compartment structure.

[0069] By setting the fixed corner piece 407a, the connection stability between the main support column 401 and the bottom support frame layer 10 connected to it is improved, which is conducive to further improving the overall stability and vibration resistance of the vehicle-mounted cooling compartment structure.

[0070] By setting up a protective triangular structure 407b, which is a three-sided corner protector, and attaching it externally and fixing it to the connection point, the structural stability of the top corner of the cuboid main structure is enhanced, thereby improving the overall stability and vibration resistance of the vehicle-mounted cooling compartment.

[0071] For example, such as Figure 9 As shown, the protective triangular structure 407b is fixedly connected to the outside of the connection between the horizontal top main beam 31, the longitudinal top main beam 32, the supporting main column 401, and the trapezoidal frame 70.

[0072] In some embodiments, such as Figure 6 As shown, on the same side of the rectangular main structure, the distance between the ends of two adjacent diagonal bracing rods 4071 along the third direction Z that are far apart is T, and the distance S between the ends of two adjacent diagonal bracing rods 4071 that are close to each other along the third direction Z is 0≤S≤T / 2; and / or as shown Figure 3As shown, the angle B2a between the side diagonal support rod 4071, which is located on the side of the rectangular main structure extending along the first direction X, and the first direction X is 25°≤B2a≤75°; and / or as shown Figure 7 As shown, the angle B2b between the side diagonal support rod 4071, which is located on the side of the rectangular main structure extending along the second direction Y, and the second direction Y is 25°≤B2b≤75°.

[0073] By ensuring that S is within the range of 0 ≤ S ≤ T / 2, columns such as the main support column 401, the first reinforcing column 402a, or the second reinforcing column 402b, which are connected to two adjacent side diagonal bracing rods 4071 along the third direction Z, can be supported by the two adjacent side diagonal bracing rods 4071 over a large height range. This improves the connection stability between the corresponding columns and the beams of the bottom support frame layer 10, the middle support frame layer 20, the top support frame layer 30, and the interlayer connection structure 40 connected to the columns. This further enhances the overall structural strength and stiffness of the cuboid main structure and improves the stability and vibration resistance of the overall structure of the vehicle-mounted cooling compartment. By ensuring that 25° ≤ B2a ≤ 75° and / or 25° ≤ B2b ≤ 75°, the diagonal angle of the side diagonal bracing rods 4071 is within a reasonable range. This allows the side diagonal bracing rods 4071 to be subjected to axial force as much as possible, fully utilizing their load-bearing capacity.

[0074] In some embodiments, such as Figures 1 to 4 As shown, the bottom inner support frame includes a transverse bottom reinforcing beam 14 extending along a first direction X and a longitudinal bottom reinforcing beam 13 extending along a second direction Y. The longitudinal bottom reinforcing beam 13 is fixedly connected to two transverse bottom main beams 11, and the transverse bottom reinforcing beam 14 is fixedly connected to two adjacent longitudinal bottom reinforcing beams 13 or fixedly connected to adjacent longitudinal bottom reinforcing beams 13 and longitudinal bottom main beams 12; and / or as shown Figure 3 As shown, the intermediate inner support frame includes a transverse reinforcing beam 23 extending along a first direction X and a longitudinal reinforcing beam 25 extending along a second direction Y. The transverse reinforcing beam 23 is located between two transverse intermediate main beams 21. The longitudinal reinforcing beam 25 is fixedly connected to two adjacent transverse reinforcing beams 23 or fixedly connected to adjacent transverse reinforcing beams 23 and transverse main beams 21, or at least one transverse main beam 21 and / or at least one transverse reinforcing beam 23 and / or at least one longitudinal reinforcing beam 25 are fixedly connected to the interlayer connection structure 40; and / or as shown in the figure. Figure 2 and Figure 9 As shown, the top inner support frame includes multiple longitudinal top reinforcing beams 33 extending along the second direction Y, and the longitudinal top reinforcing beams 33 are fixedly connected to two transverse top main beams 31.

[0075] The bottom inner support frame and / or the middle inner support frame and / or the top inner support frame include corresponding crossbeams and longitudinal beams. By reasonably setting the number, structure (e.g., whether the profile is channel steel or angle steel), size, position and connection relationship of the crossbeams and longitudinal beams of each inner support frame, the overall structural strength of the corresponding support frame layer and the structural strength of each internal part can be reasonably set so as to match the equipment (e.g., refrigeration module) or structure supported by each support frame layer (e.g., the middle inner support frame is formed by the bottom inner support frame supporting the middle inner support frame to form the structure supported by the bottom inner support frame) and the required support performance of the equipment and / or structure supported by each support frame layer.

[0076] In some embodiments, such as Figures 1 to 3 As shown, the multiple inter-layer support frames include a first inter-layer support frame located on the side of the cuboid main structure extending along the first direction X. The first inter-layer support frame includes multiple first reinforcing columns 402a extending along the third direction Z and spaced apart along the first direction X. The multiple first reinforcing columns 402a are arranged between two supporting main columns 401 on the same side and are fixedly connected to the transverse bottom main beam 11 and transverse top main beam 31 on the same side.

[0077] By using multiple first reinforcing columns 402a, the load on the supporting main column 401 can be reduced, and the bending degree of the transverse top main beam 31 and transverse middle main beam 21 connected to the interlayer support frame where the multiple first reinforcing columns 402a are located can be reduced when subjected to downward load. This helps to reduce the bending moment of the multiple first reinforcing columns 402a themselves and the two supporting main columns 401 on both sides of the interlayer support frame along the first direction X. This helps to avoid damage to the connection structure at the root of the corresponding supporting main column 401 and first reinforcing column 402a due to excessive bending moment. It also increases the overall stiffness of the side of the cuboid main structure where the first interlayer support frame is located and the connection strength between it and the bottom support frame layer 10, the middle support frame layer 20, and the top support frame layer 30. This helps to improve the stability and vibration resistance of the overall structure of the vehicle-mounted cooling compartment.

[0078] In some embodiments, such as Figure 3 As shown, the relationship between the length L of the transverse top main beam 31 along the first direction X and the spacing d between the multiple first reinforcing columns 402a along the first direction X satisfies L / 6≤d≤L / 4.

[0079] By ensuring that L / 6 ≤ d ≤ L / 4, it is beneficial to rationally set the spacing of multiple first reinforcing columns 402a, enabling the multiple first reinforcing columns 402a to distribute the load borne by the supporting main column 401 more evenly. This helps to reduce the bending degree of the transverse top main beam 31 and transverse middle main beam 21 connecting the interlayer support frame where the multiple first reinforcing columns 402a are located when subjected to downward loads. This, in turn, helps to reduce the bending moment of the multiple first reinforcing columns 402a themselves and the two supporting main columns 401 on both sides of the interlayer support frame along the first direction X. This helps to avoid damage to the connection structure at the root of the corresponding supporting main column 401 and first reinforcing column 402a due to excessive bending moment, thereby improving the overall stability and vibration resistance of the vehicle-mounted cooling compartment structure.

[0080] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the multiple inter-layer support frames include a second inter-layer support frame extending along a first direction X. The second inter-layer support frame includes a second reinforcing column 402b extending along a third direction Z. The second reinforcing column 402b is fixedly connected to the transverse bottom main beam 11 and the transverse top main beam 31 on the same side. The second inter-layer support frame also includes an open frame beam 405 extending along the first direction X. The open frame beam 405 extends along the third direction Z above the intermediate support frame layer 20 and is fixedly connected to adjacent supporting main columns 401 and second reinforcing columns 402b, or fixedly connected to two adjacent second reinforcing columns 402b, forming an opening 40A below the open frame beam 405 on the side where the second inter-layer support frame is located. The intermediate support frame layer 20 has a notch opposite to the opening 40A; and / or, as Figure 4As shown, the second-layer internal support frame also includes a transverse reinforcing beam 404 extending along the first direction X and a third reinforcing column 406 extending along the third direction Z. The transverse reinforcing beam 404 is fixedly connected to adjacent main support columns 401 and second reinforcing columns 402b, or fixedly connected to two adjacent second reinforcing columns 402b. The third reinforcing column 406 is fixedly connected to the transverse top main beam 31 and the transverse reinforcing beam 404 on the same side. Similar to the first reinforcing column 402a, the second reinforcing column 402b can reduce the load on the supporting main column 401 and reduce the bending degree of the transverse top main beam 31 and transverse middle main beam 21 connected to the interlayer support frame where the second reinforcing column 402b is located when subjected to downward load. This helps to reduce the bending moment of the second reinforcing column 402b itself and the two supporting main columns 401 on both sides of the interlayer support frame along the first direction X, thereby helping to avoid damage to the connection structure at the root of the corresponding supporting main column 401 and the second reinforcing column 402b due to excessive bending moment. It also increases the overall stiffness of the side of the cuboid main structure where the second interlayer support frame is located and the connection strength between it and the bottom support frame layer 10, the middle support frame layer 20 and the top support frame layer 30, thereby improving the stability and vibration resistance of the overall structure of the vehicle-mounted cooling compartment.

[0081] The gap in the intermediate support frame layer 20 connects the spaces on both sides of the gap to form a relatively large space between the bottom support frame layer 10 and the top support frame layer 30. This space can be used to house equipment requiring higher space, other than the refrigeration module 80, such as a power control box. The opening 40A allows for access to equipment or tools during installation and maintenance of equipment in the higher space, or facilitates equipment installation, maintenance, or operation.

[0082] The transverse reinforcing beam 404 and the third reinforcing column 406 are provided to increase the overall rigidity of the side of the cuboid main structure where the second interlayer support frame is located and the connection strength between it and the bottom support frame layer 10, the middle support frame layer 20 and the top support frame layer 30. At the same time, the bottom of the transverse reinforcing beam 404 forms an opening to provide an access passage for the space between the bottom support frame layer 10 and the middle support frame layer 20 installed inside the opening. This facilitates the entry and exit of equipment or tools when installing and maintaining equipment in the space, or facilitates the installation, maintenance or operation of equipment.

[0083] In some embodiments, such as Figure 1 , Figure 2 and Figure 5As shown, the multiple inter-layer support frames include a third inter-layer support frame located on the side of the cuboid main structure extending along the second direction Y. The third inter-layer support frame includes a first longitudinal intermediate reinforcing beam 413 extending along the second direction Y and a fourth reinforcing column 411 extending along the third direction Z. The fourth reinforcing column 411 is fixedly connected to the longitudinal bottom main beam 12 and the longitudinal top main beam 32. The first longitudinal intermediate reinforcing beam 413 is fixedly connected to the supporting main column 401 and the fourth reinforcing column 411 on the same side.

[0084] The fourth reinforcing column 411 and the first longitudinal intermediate reinforcing beam 413 of the inner support frame of the third layer, together with the main supporting columns 401 on both sides along the second direction Y, the longitudinal bottom main beam 12 at the bottom, and the longitudinal top main beam 32 at the top, form a grid-shaped structure. This structure is beneficial to improving the strength of the side of the cuboid main structure where the inner support frame of the third layer is located, and is beneficial to bearing the forces in the first direction X, the second direction Y, and the third direction Z, thereby improving the stability and vibration resistance of the overall structure of the vehicle-mounted cooling compartment.

[0085] In some embodiments, such as Figure 1 , Figure 2 and Figure 6 As shown, the multiple inter-layer support frames include a fourth inter-layer support frame extending along the second direction Y on the side of the cuboid main structure. The fourth inter-layer support frame includes a second longitudinal intermediate reinforcing beam 414 extending along the second direction Y and a fifth reinforcing column 412 extending along the third direction Z. The second longitudinal intermediate reinforcing beam 414 is fixedly connected to two main supporting columns 401 on one side. The fifth reinforcing column 412 is fixedly connected to the second longitudinal intermediate reinforcing beam 414 and a longitudinal top main beam 32 on one side.

[0086] The second longitudinal intermediate reinforcing beam 414 and the fifth reinforcing column 412 are provided to increase the overall rigidity of the sides of the cuboid main structure where the fourth interlayer support frame is located, as well as the connection strength with the bottom support frame layer 10, the intermediate support frame layer 20, and the top support frame layer 30. Simultaneously, an opening is formed at the bottom of the second longitudinal intermediate reinforcing beam 414 to provide an access passage for the space between the bottom support frame layer 10 and the intermediate support frame layer 20, which are installed inside the opening. This facilitates the entry and exit of equipment or tools during installation and maintenance of equipment within the space, or facilitates equipment installation, maintenance, or operation.

[0087] In some embodiments, such as Figures 1 to 4 and Figure 7 As shown, the interlayer connection structure 40 also includes an internal support structure, which is located inside the cuboid main structure and is fixedly connected to at least two of the bottom inner support frame, the intermediate support frame layer 20 and the interlayer connection structure 40 so that the bottom support frame layer 10 supports the intermediate support frame layer 20 through the internal support structure.

[0088] The internal support structure can reduce the load on the main support column 401 and the interlayer support frame, and can provide sufficient support for the parts of the intermediate support frame layer 20 that are far from the main support column.

[0089] In some embodiments, such as Figures 1 to 4 As shown, the interlayer connection structure also includes an internal reinforcement structure. The internal reinforcement structure is fixedly connected to at least one of the internal support structure, the bottom internal support frame, the intermediate support frame layer 20, and the interlayer internal support frame.

[0090] The internal reinforcement structure strengthens the connection between the internal support structure and the bottom inner support frame, intermediate support frame layer 20, or interlayer inner support frame, reducing the load at the connection points and stress concentration. Furthermore, the internal reinforcement structure can suppress torsional deformation caused by asymmetrical loads or uneven local stress at the connection points, thereby improving the stability and vibration resistance of the vehicle-mounted cooling compartment.

[0091] In some embodiments, such as Figure 3 and Figure 4 As shown, the internal support structure includes: a sixth reinforcing column 4091, extending in the third direction Z, and fixedly connecting the intermediate support frame layer 20 and the bottom inner support frame; and / or as shown in the figure. Figure 3 As shown, the X-shaped connection structure 408 includes two inclined beams that are cross-fixed and connected in an X-shape, inclined at different angles relative to the plane containing the first direction X and the second direction Y. The plane containing the X-shaped connection structure 408 is perpendicular to the first direction X. The X-shaped connection structure 408 is fixedly connected to the bottom inner support frame of the bottom support frame layer 10 and the middle support frame layer 20; and / or as shown in the figure. Figure 4 As shown, the inclined connecting rod 410 is fixedly connected to the bottom inner support frame and the interlayer inner support frame.

[0092] Setting up the sixth reinforcing column 4091 helps to improve the structural strength of the internal support structure along the third direction Z through a simple structure, thereby improving the support capacity for the intermediate support frame layer 20.

[0093] The X-type connection structure 408 also helps to improve the structural strength of the internal support structure along the third direction Z, improve the support capacity of the intermediate support frame layer 20, and at the same time improve the ability to resist deformation along the second direction Y between the bottom support frame layer 10 and the intermediate support frame layer 20.

[0094] The diagonal connecting rod 410 can provide support to the second reinforcing column 402b along the second direction Y and the third direction Z, which helps to improve the stability of the support frame in the second layer.

[0095] In some embodiments, such as Figure 3 or Figure 4 As shown, the interlayer connection structure also includes an internal reinforcement structure. The internal reinforcement structure is fixedly connected to at least one of the internal support structure, the bottom inner support frame, the intermediate support frame layer 20, and the interlayer inner support frame. The internal reinforcement structure includes an internal diagonal bracing rod 4092 disposed between the sixth reinforcing column 4091 and the bottom inner support frame and / or includes an internal diagonal bracing rod 4092 disposed between the sixth reinforcing column 4091 and the intermediate support frame layer 20.

[0096] The internal diagonal bracing rod 4092 can increase the connection between the sixth reinforcing column 4091 and the bottom inner support frame, the middle support frame layer 20, or the interlayer inner support frame, thereby further increasing the strength and rigidity of the vehicle-mounted cooling compartment, and thus improving the stability and vibration resistance of the vehicle-mounted cooling compartment.

[0097] In some embodiments, such as Figure 4 As shown, the internal support structure includes a plurality of sixth reinforcing columns 4091 arranged at intervals along the first direction X; and / or in some embodiments, such as Figure 4 As shown, the internal support structure includes a plurality of sixth reinforcing columns 4091 arranged at intervals along the second direction Y; and / or two internal diagonal support rods 4092 are simultaneously provided on both sides of at least one end of at least one of the sixth reinforcing columns 4091 along the third direction Z along the first direction X, the two internal diagonal support rods 4092 and the sixth reinforcing columns 4091 forming a ψ-shaped connection structure 409.

[0098] Multiple sixth reinforcing columns 4091 can evenly distribute the pressure exerted by the intermediate support frame layer 20 and the equipment supported on it, which helps to avoid excessive bending moments borne by a single sixth reinforcing column 4091. The formation of a ψ-shaped connection structure 409 improves the support capacity and rigidity of the vehicle-mounted cooling compartment in the plane of the ψ-shaped connection structure 409, thereby ensuring the support rigidity of the intermediate support frame layer 20 below the cooling module 80, and also improving the overall stability and vibration resistance of the vehicle-mounted cooling compartment.

[0099] In some embodiments, such as Figure 4 As shown, the included angle F6 between the sixth reinforcing column 4091 and the internal diagonal bracing rod 4092 connected to the sixth reinforcing column 4091 is 30°≤F6≤60°.

[0100] By setting the angle between the internal diagonal bracing rod 4092 and the sixth reinforcing column 4091 to be 30°≤F6≤60°, the internal diagonal bracing rod 4092 is reasonably set. This allows the internal diagonal bracing rod 4092 to be subjected to axial force as much as possible, making full use of the load-bearing capacity of the internal diagonal bracing rod and improving the support effect of the ψ-shaped connection structure 409.

[0101] In some embodiments, such as Figure 7 As shown, the included angle D4 between the two inclined beams and the bottom inner support frame is 90°≤D4≤150°.

[0102] Ensuring that 90°≤D4≤150° not only guarantees the support stiffness of the X-type connection structure 408 in the third direction Z, but also effectively improves the stiffness of the X-type connection structure 408 in the second direction Y, thereby achieving a better balance between the structural stability and stiffness performance of the bottom support frame layer 10 and the intermediate support frame layer 20. The included angle D4 between the two inclined beams can be appropriately adjusted based on the vertical spacing between the bottom support frame layer 10 and the intermediate support frame layer 20. Setting the included angle D4 is to improve the support stiffness of the refrigeration module.

[0103] In some embodiments, such as Figure 7 As shown, a side diagonal bracing rod 4071 is provided between the main support column extending along the second direction Y on the side of the cuboid main structure and the longitudinal bottom main beam connected thereto. The included angle C3 between the side diagonal bracing rod 4071 and the diagonal beam of the X-shaped connection structure 408 that intersects with the side diagonal bracing rod 4071 when viewed from the first direction X, relative to the intermediate support frame layer 20, satisfies C3 < D4.

[0104] Making C3 < D4 helps ensure the support stiffness of the side diagonal support rod 4071 in the second direction Y at its bottom corner and also helps improve the support stiffness of the main support column 401 to which it is connected.

[0105] In some embodiments, such as Figure 7 As shown, the angle E5 between the inclined connecting rod 410 and the second direction Y is 40°≤E5≤70°.

[0106] By ensuring that 40°≤E5≤70°, the support stiffness of the inclined connecting rod 410 to the second reinforcing column 402b connected to it is improved, thereby enhancing the stability and vibration resistance of the vehicle-mounted cooling compartment.

[0107] In some embodiments, such as Figure 9 As shown, the vehicle-mounted cooling compartment also includes a trapezoidal frame 70, which is fixedly connected to the top support frame layer 30.

[0108] The trapezoidal frame 70 helps to improve the structural strength and rigidity of the top of the cuboid main structure, improve the overall stability and vibration resistance of the vehicle-mounted cooling compartment, and also facilitates the installation of air ducts in the refrigeration module 80 and protects the equipment or structure inside the air duct, such as the fan 82.

[0109] In some embodiments, such as Figure 9As shown, the vehicle-mounted cooling compartment also includes a ventilation frame 90, which is installed between the top support frame layer 30 and the trapezoidal frame 70 and is configured to enclose the mounting space of the fan 82 of the cooling module 80.

[0110] The ventilation frame 90 can force the waste heat generated by the cooling module upwards, preventing hot air from circulating and accumulating inside the equipment, and also avoiding the disorderly discharge of hot air from affecting the environmental comfort of surrounding equipment or personnel.

[0111] In some embodiments, such as Figure 9 As shown, the trapezoidal frame 70 includes a main frame beam 71 and two trapezoidal main beams 72. The main frame beam 71 extends along a first direction X, and both ends of the main frame beam 71 are fixedly connected to the two trapezoidal main beams 72. The two trapezoidal main beams 72 are correspondingly arranged with two longitudinal top main beams 32. The two ends of the two trapezoidal main beams 72 are respectively fixedly connected to the corners of the cuboid main structure at both ends of the corresponding longitudinal top main beams 32.

[0112] The trapezoidal main structure of the trapezoidal frame 70 is realized by combining the frame main beam 71 and the trapezoidal main beam 72. The structural form of the trapezoidal main structure is conducive to further improving the structural strength and stiffness of the top of the cuboid main structure.

[0113] In some embodiments, such as Figure 9 As shown, the bending angle A1 of the trapezoidal main beam 72 is within 120°≤A1≤180°.

[0114] Making 120°≤A1≤180° helps to improve the rigidity and stability of the trapezoidal frame 70 itself, thereby further improving the structural strength and rigidity of the top of the cuboid main structure, ensuring the air outlet area and air outlet distance during module operation, and facilitating the elimination of water accumulation on the top during rain and snow.

[0115] In some embodiments, such as Figure 9 As shown, the trapezoidal frame 70 also includes trapezoidal frame columns 73 extending in the third direction Z, which are fixedly connected to the main frame beam 71 and the top inner support frame of the top support frame layer 30; and / or as shown Figure 9 As shown, the trapezoidal frame 70 also includes an angular reinforcing beam 74, a fixedly connected frame main beam 71, and a transverse top main beam 31.

[0116] The trapezoidal frame column 73 provides support for the main frame beam 71 of the trapezoidal frame 70 along the third direction Z and enhances the stability of the trapezoidal frame 70. The angled reinforcing beam 74 provides support for the main frame beam 71 of the trapezoidal frame 70 along the second direction Y and the third direction Z and enhances the stability of the trapezoidal frame 70.

[0117] In some embodiments, such as Figure 9As shown, the trapezoidal frame 70 also includes an angled plate frame 75, which is fixedly connected to the inner edge of the frame formed between the transverse top main beam 31, the frame main beam 71, and the angled reinforcing beam 74, and / or the angled plate frame 75 is fixedly connected to the inner edge of the frame formed between the transverse top main beam 31, the frame main beam 71, the trapezoidal main beam 72, and the angled reinforcing beam 74.

[0118] The angular plate frame 75 is fixedly connected to the transverse top main beam 31, the frame main beam 71, and the angular reinforcing beam 74, or is fixedly connected to the transverse top main beam 31, the frame main beam 71, the trapezoidal main beam 72, and the angular reinforcing beam 74, thereby strengthening the structural strength and rigidity of the trapezoidal frame 70, and thus strengthening the structural strength and rigidity of the top and the whole of the vehicle-mounted cooling compartment.

[0119] In some embodiments, such as Figure 1 and Figure 10 As shown, the vehicle-mounted cooling equipment includes at least one refrigeration module 80, a vehicle-mounted cooling compartment as described in the previous embodiment, and a module connection structure 60. The refrigeration module 80 includes a refrigeration unit 81. The module connection structure 60 includes a first connector 61. The refrigeration unit 81 is supported on the intermediate support frame layer 20 and fixedly connected to the vehicle-mounted cooling compartment via the first connector 61.

[0120] The vehicle-mounted cooling device of this application embodiment has the advantages of the vehicle-mounted cooling compartment of this application embodiment. By fixing the refrigeration module 80 to the vehicle-mounted cooling compartment through the first connector 61, the refrigeration module 80 can be stably supported on the intermediate support frame layer 20 of the vehicle-mounted cooling compartment.

[0121] In some embodiments, such as Figure 1 and Figure 10 As shown, the vehicle-mounted cooling equipment includes multiple cooling modules 80, and the module connection structure 60 further includes a second connector 62, which is fixedly connected to the cooling host 81 of two adjacent cooling modules 80 arranged along the first direction X; and / or, as shown Figure 10 As shown, the module connection structure 60 also includes a third connector 63, which is fixedly connected to the refrigeration host 81 of two adjacent refrigeration modules 80 arranged along the second direction Y.

[0122] Multiple refrigeration modules 80 can be connected together by the second connector 62 and / or the third connector 63, thereby ensuring a stable connection between the multiple refrigeration modules 80 and the vehicle-mounted cooling compartment, which helps to improve the overall stability and vibration resistance of the vehicle-mounted cooling equipment.

[0123] The following is a combination of appendices Figures 1 to 10 The structure of the vehicle-mounted cooling compartment and vehicle-mounted cooling equipment according to some embodiments of this application will be described in more detail.

[0124] like Figures 1 to 10 As shown, the vehicle-mounted cooling device in this embodiment includes multiple cooling modules 80, a vehicle-mounted cooling chamber, and a module connection structure 60.

[0125] The vehicle-mounted cooling compartment includes a bottom support frame layer 10, a middle support frame layer 20, a top support frame layer 30, an interlayer connection structure 40, a trapezoidal frame 70, and a ventilation frame 90.

[0126] The bottom support frame layer 10, the middle support frame layer 20, the top support frame layer 30, and the trapezoidal frame 70 are each welded together using profiles. The interlayer connection structure 40 is welded to the bottom support frame layer 10, the middle support frame layer 20, and the top support frame layer 30 to form a rectangular main structure.
