Description

Technical Field

[0001] This invention relates to the field of heat exchange, and more specifically to a heat exchange device and a transport device. Background Technology

[0002] With the iterative upgrades of special transport equipment such as special vehicles, unmanned aerial vehicle platforms, deep-sea operation vessels, and high-speed patrol boats, the integration and power density of core electronic devices such as communication base stations and power control systems on these vehicles are continuously increasing. This leads to a significant increase in heat loss during equipment operation, placing higher demands on the heat dissipation efficiency, space adaptability, and operational stability of cooling systems.

[0035] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment shall be considered part of the specification.

[0036] The dimensions of the various parts shown in the accompanying drawings are not drawn to actual scale. Common structural elements or elements of the same kind are given the same reference numerals in the various drawings, and repeated descriptions of them are omitted where appropriate.

[0037] This invention provides a heat exchange device, including a support assembly 1, a variable frequency compressor 2, a first heat exchanger 3, and a second heat exchanger 4. The support assembly 1 includes a frame body 101, a base plate 102, and a reinforcing member 103; the frame body 101 is fixedly connected to the base plate 102, and the reinforcing member 103 is installed on the frame body 101. The variable frequency compressor 2 is installed inside the frame body 101. The first heat exchanger 3 communicates with the variable frequency compressor 2 and is located inside the frame body 101, and is fixedly connected to the frame body 101 and / or the base plate 102. The second heat exchanger 4 communicates with the variable frequency compressor 2 and is located inside the frame body 101, and is fixedly connected to the first heat exchanger 3 and / or the base plate 102.

[0038] The frame body 101 and the base plate 102 are fixedly connected to form the load-bearing base of the whole machine. The reinforcing member 103 is assembled to the frame body 101. The reinforcing member 103 strengthens the structure of the frame body 101 so that the frame body 101 can withstand the vibration load generated during the operation of the variable frequency compressor 2, the first heat exchanger 3, and the second heat exchanger 4.

[0039] See Figures 2 to 5 In some embodiments, the frame body 101 includes multiple uprights 1011 and multiple crossbeams 1012. Specifically, there are 4-6 uprights 1011 and 8-16 crossbeams 1012. Each upright 1011 includes a first plate 1011a and a second plate 1011b, which are fixedly connected at an angle or integrally, for example, vertically. A reinforcing member 103 is installed at the connection between the first plate 1011a and the second plate 1011b; the side of the first plate 1011a away from the second plate 1011b is bent, and the side of the second plate 1011b away from the first plate 1011a is also bent. Each crossbeam 1012 is disposed between two adjacent uprights 1011 and fixedly connected to the uprights 1011. The base plate 102 is fixedly connected to at least one upright 1011 and at least one crossbeam 1012.

[0040] The first plate 1011a and the second plate 1011b are joined together to form the main structure of the column 1011. The bending structure on both sides increases the cross-sectional strength of the column 1011. The reinforcing member 103 strengthens the structural stability at the connection between the two plates, reducing or even avoiding stress concentration at the corners of the column 1011. The crossbeam 1012 provides lateral connection and restraint for adjacent columns 1011, ensuring that the multiple columns 1011 maintain a regular spacing and verticality. The base plate 102 is fixed at multiple points by relying on the columns 1011 and the crossbeam 1012, further improving the overall assembly integrity and load-bearing stability of the overall support component 1.

[0041] In some embodiments, the heat exchange device is optimized for cost reduction and weight reduction. The frame body 101 is formed from 3mm thick hot-rolled steel plate. The first plate 1011a and the second plate 1011b are reinforced by triangular reinforcing members 103, without relying on increasing the thickness of the plates to improve structural performance. This solution can reduce material consumption and lighten the overall weight of the unit, while ensuring the overall vibration resistance of the unit, making it suitable for use in vehicles and ships with high vibration and impact.

[0042] During use, the equipment's own weight, vibration load, and external impact load will act simultaneously on the column 1011 and the crossbeam 1012. The bending structure on both sides of the column 1011 can disperse the vertical and lateral forces, the reinforcing member 103 stabilizes the weak corner of the column 1011, and the crossbeam 1012 can restrain the lateral deformation of the column 1011, making the overall support assembly 1 less prone to twisting and deformation, and continuously providing a stable installation foundation for various internal heat exchange components and electrical control components.

[0043] The aforementioned technical solution provides the column 1011 with higher structural rigidity and deformation resistance, effectively improving the overall seismic and impact resistance of the frame body 101. The reinforcing member 103 specifically strengthens the corner connection positions of the column 1011, reducing or even preventing cracking and loosening under long-term vibration conditions. The combined support assembly 1 structure of the column 1011 and the crossbeam 1012, along with the multi-point base plate 102 for fixation, results in more uniform overall stress distribution, making it suitable for the complex operating environment of special vehicles and special vessels subjected to long-term turbulence and vibration, ensuring the long-term stable operation of the heat exchange device.

[0044] See Figure 6 In some embodiments, the heat exchange device further includes a compressor mounting assembly 11, which includes multiple support columns 1101 and multiple auxiliary legs 1102. Each support column 1101 is fixedly connected to one auxiliary leg 1102. The support columns 1101 are distributed circumferentially along the compressor. One end of each support column 1101 is fixedly connected to the housing of the variable frequency compressor 2, and the other end of each support column 1101 is fixedly connected to the base plate 102. The top end of each auxiliary leg 1102 is fixedly connected to the corresponding support column 1101, and the bottom end of each auxiliary leg 1102 is away from the bottom end of the support column 1101 and is fixedly connected to the base plate 102.

[0045] Three to six support columns 1101 and auxiliary legs 1102 are arranged around the circumference of the variable frequency compressor 2. For example, four sets are set to support and fix the variable frequency compressor 2 from four different angles. A rubber pad is placed between the compressor fixing component 11 and the variable frequency compressor 2 to reduce vibration.

[0046] Multiple support columns 1101 arranged circumferentially around the variable frequency compressor 2 provide point support for the compressor 2. The upper and lower ends of the support columns 1101 are respectively connected to the casing of the variable frequency compressor 2 and the base plate 102. The auxiliary legs 1102 and the support columns 1101 form an oblique support structure. The bottom ends of the auxiliary legs 1102 are extended outward and fastened to the surface of the base plate 102. Specifically, the support columns 1101 can be evenly arranged circumferentially around the casing of the variable frequency compressor 2, and the auxiliary legs 1102 are inclined outward to form a triangular support structure. The assembly load generated by the variable frequency compressor 2 is transferred to the base plate 102 through the support columns 1101 and the auxiliary legs 1102. The frame body 101, together with the reinforcing members 103, bears the lateral load of the entire machine.

[0047] The compressor mounting assembly 11 is equipped with support columns 1101 and outwardly inclined auxiliary legs 1102, which can form multi-point triangular support constraints for the variable frequency compressor 2, improving the structural rigidity of the installation position of the variable frequency compressor 2. The support columns 1101 and auxiliary legs 1102 jointly share the vibration impact generated by the compressor operation, reducing the possibility of the variable frequency compressor 2 shaking and shifting, and reducing the risk of loosening of pipeline interfaces caused by vibration. Multiple sets of support structures are distributed around the circumference of the compressor, which can evenly bear the vibration load in various directions, adapting to the bumpy and vibration environment during the operation of vehicle and ship equipment.

[0048] The variable frequency compressor 2 is placed inside the frame body 101. The variable frequency compressor 2, the first heat exchanger 3, and the second heat exchanger 4 form a refrigerant circulation loop to complete the refrigerant circulation. The variable frequency compressor 2 can adjust its output power in real time according to the heat load. When the heat source load fluctuates, it can match the corresponding cooling capacity. When the load is low, the power is reduced to reduce ineffective energy consumption and achieve energy-saving operation; when the load is high, the power is increased to ensure sufficient heat dissipation capacity and avoid local overheating of electronic equipment. Compared with the fixed frequency compressor, the variable frequency compressor 2 has higher temperature control accuracy and can adapt to the heat dissipation requirements of dynamic changes in heat sources under special vehicle and ship operating conditions, reducing energy consumption and energy waste.

[0049] The first heat exchanger 3 is installed and positioned by being fixedly connected to the frame body 101 or the base plate 102. Specifically, the first heat exchanger 3 can be fixed only to the frame body 101, only to the base plate 102, or simultaneously to both the frame body 101 and the base plate 102. In some embodiments, the first heat exchanger 3 is connected to both the frame body 101 and the base plate 102, thereby forming a multi-point assembly constraint structure.

[0050] A first vibration damping element, such as a rubber pad, can be installed between the first heat exchanger 3 and the frame body 101, and between the first heat exchanger 3 and the support assembly 1, to achieve vibration damping. The first vibration damping element is sandwiched between the first heat exchanger 3 and the support assembly 1. After assembly, the first vibration damping element abuts against the first heat exchanger 3 and the support assembly 1, and can abut against the frame body 101 or the base plate 102. When vibration occurs during equipment operation, the first vibration damping element can absorb some of the vibration energy, weakening the vibration transmitted from the support assembly 1 to the first heat exchanger 3.

[0051] In some embodiments, the first heat exchanger 3 is a finned heat exchanger configured in a U-shape.

[0052] The dustproof performance of the fins and the corrosion resistance of the sheet metal parts of the first heat exchanger 3 can be optimized. The first heat exchanger 3 is a condenser, and the condenser adopts a finned heat exchanger. This structure has a good dustproof effect and is also easy to clean and maintain later.

[0053] In some embodiments, the first heat exchanger 3 and the frame body 101 are shaped to match, with the first heat exchanger 3 attached to the inner wall of the frame body 101. That is, the finned heat exchanger and the frame body 101 are shaped to match each other, the finned heat exchanger is arranged against the inner wall of the frame body 101, and is fixedly connected to the column 1011 of the frame body 101 by bolts. The top perimeter of the finned heat exchanger is held in place by sheet metal brackets; and the base plate 102 is also provided with limiting slots for the finned heat exchanger. Through these fixing measures, the finned heat exchanger can be firmly fixed, greatly reducing the risk of pipe breakage due to vibration fatigue. Furthermore, the U-shaped bending profile adapts to the internal cavity space of the frame body 101, and pipe connection positions are reserved at both ends of the finned heat exchanger, with refrigeration pipes connecting the finned heat exchanger and the variable frequency compressor 2 respectively. After the U-shaped finned heat exchanger is attached to the inner wall of the frame body 101, the frame body 101 and the base plate 102 can jointly bear the vibration generated by the operation of the finned heat exchanger.

[0054] The first heat exchanger 3 is arranged against the frame body 101. After assembly, the first heat exchanger 3 is in contact with the inner wall of the frame body 101, either directly or through the first vibration damping element described herein. Specifically, the overall outer contour of the first heat exchanger 3 is set according to the inner wall contour of the frame body 101. For example, if the inner wall of the frame body 101 is a planar structure, the corresponding outer wall of the first heat exchanger 3 is also planar, thereby achieving a large-area fit between the two.

[0055] The above technical solution limits the first heat exchanger 3 by using the inner wall of the frame body 101, allowing the first heat exchanger 3 to be positioned against the inner wall of the frame body 101. During use, the vibration generated by the operation of the first heat exchanger 3 can be directly transmitted to the inner wall of the frame body 101. The frame body 101, together with the reinforcing member 103, jointly bears the vibration load, thus constraining the displacement of the first heat exchanger 3 during operation, reducing the risk of pipe joint loosening caused by vibration, reducing the alternating vibration load on the connecting pipe between the heat exchanger and the variable frequency compressor 2, and improving the operational reliability of the pipe connection position.

[0056] In addition, the first heat exchanger 3 is adapted to the shape of the inner wall of the frame body 101 and is arranged close to it, which can make full use of the existing space inside the frame body 101, reduce the installation gap reserved separately for the first heat exchanger 3, and further improve the utilization rate of the internal space of the frame body 101.

[0057] Furthermore, the first heat exchanger 3 is configured as a U-shaped finned heat exchanger, which has a large heat exchange area and can effectively improve the heat exchange capacity. The U-shaped structure can adapt to the internal cavity contour of the frame body 101, making full use of the corner space of the frame body 101, improving the space utilization rate inside the support component 1, and facilitating the miniaturized integrated layout of the whole machine. The U-shaped overall structure has higher rigidity, and under equipment vibration conditions, the finned heat exchanger's own deformation resistance is improved, reducing the probability of fin deformation and detachment failure.

[0058] In addition, the first heat exchanger 3 adopts a U-shaped condenser structure, and one side of the unit is reserved as a maintenance surface for the heat exchange device, for installing the maintenance plate P. The electrical control box 7, which will be described later, is independently set as a detachable module. The electrical control box 7 is located at the opening of the first heat exchanger 3, that is, near the location of the maintenance plate P.

[0059] This structural layout ensures high-efficiency heat exchange performance while overcoming the drawbacks of inconvenient maintenance of key electrical components in traditional heat exchange modules. Currently, by opening the unit's inspection panel and the control box 7 panel, some key internal electrical components can be maintained, repaired, or replaced, greatly improving maintenance convenience, simplifying the maintenance process, and reducing maintenance costs during the warranty period of the heat exchange device, while simultaneously balancing the equipment's heat dissipation efficiency and ease of maintenance.

[0060] In some embodiments, the first heat exchanger 3 includes a first branch and a second branch connected in parallel, and the first branch or the second branch is provided with a regulating valve 301.

[0061] The internal flow path of the first heat exchanger 3 is configured as two layers, connected by a manifold. The manifold, similar to a three-way valve, divides the refrigerant flowing into the first heat exchanger 3 into two paths, one leading to the first branch and the other to the second branch. A regulating valve 301 is installed on the upper refrigerant flow path of the first heat exchanger 3, i.e., the first branch. When the regulating valve 301 is closed, the heat dissipation equipment operates in the lowest energy consumption mode, allowing refrigerant flow only through the second branch. When the regulating valve 301 is open, the equipment operates at its highest power for cooling efficiency. The regulating valve 301 has a pulse start-stop function, allowing for customized start-stop times based on different operating conditions and user needs, such as opening for 10 seconds and then closing for 1 second, or opening for 20 seconds and then closing for 2 seconds.

[0062] In addition, the control unit can be set to output commands to control the regulating valve 301. The amount of refrigerant in the first heat exchanger 3 can be adjusted by the pulse on / off of the regulating valve 301, thereby adjusting the cooling capacity output by the heat exchange device. This allows the heat exchange device to operate efficiently and energy-savingly under different operating conditions, achieving a more energy-saving and precise temperature control effect.

[0063] The second heat exchanger 4 is installed and positioned by a fixed connection with the first heat exchanger 3 or the base plate 102. The second heat exchanger 4 can be fixed only to the first heat exchanger 3, only to the base plate 102, or simultaneously to both the first heat exchanger 3 and the base plate 102. In some embodiments, the second heat exchanger 4 is connected to both the first heat exchanger 3 and the base plate 102, thereby forming a multi-point assembly constraint structure.

[0064] A second vibration damping element, such as a rubber pad, can be installed between the second heat exchanger 4 and the support assembly 1 to achieve vibration reduction. The second vibration damping element is clamped in the gap between the outer periphery of the second heat exchanger 4 and the support assembly 1. In the assembled state, the second vibration damping element abuts against the outer wall of the second heat exchanger 4 and the support assembly 1, and can abut against the frame body 101 or the base plate 102. When the equipment is subjected to bumps and disturbances, the second vibration damping element can buffer the contact impact between the two and block some of the vibration transmitted from the frame body 101 to the second heat exchanger 4.

[0065] See Figure 7 In some embodiments, the heat exchange device further includes a heat exchanger fixing assembly 12, which is fixedly installed inside the frame body 101 and encloses at least a portion of the outer periphery of the second heat exchanger 4.

[0066] The heat exchanger fixing assembly 12 is securely connected to the frame body 101. The heat exchanger fixing assembly 12 covers a portion of the outer periphery of the second heat exchanger 4 from the outside, providing lateral restraint to the second heat exchanger 4. By enclosing at least part of the outer periphery of the second heat exchanger 4, the heat exchanger fixing assembly 12 provides lateral protection, reducing the probability of displacement of the second heat exchanger 4 under turbulent operating conditions. The heat exchanger fixing assembly 12 shares the vibration load borne by the second heat exchanger 4, reducing the stress on the connection points between the second heat exchanger 4 and other components, and improving the operational reliability of pipe joints. The heat exchanger fixing assembly 12 is installed inside the frame body 101, eliminating the need for additional external space occupied by the support assembly 1, allowing the entire unit to maintain a compact integrated layout.

[0067] Specifically, the second heat exchanger 4 is a plate evaporator. The plate heat exchanger is surrounded and fixed by heat exchanger fixing components 12. Rubber pads are attached to the contact surfaces of the heat exchanger fixing components 12 and the plate evaporator, and the two are tightly fitted together to reduce vibration.

[0068] The first heat exchanger 3, the second heat exchanger 4, and the variable frequency compressor 2 are all housed within the internal space enclosed by the frame body 101. The core working components of the heat exchange device are all located inside the frame body 101, reducing the space occupied by individual component placement and facilitating the overall miniaturization and integration of the heat exchange device, making it suitable for the limited installation space of special equipment. The frame body 101 provides physical protection for the internal variable frequency compressor 2, the first heat exchanger 3, and the second heat exchanger 4, buffering external impacts and confining the vibrations generated by the operation of the components within the support assembly 1, reducing the outward transmission of vibrations and meeting the high-vibration and confined installation space requirements of special vehicles and vessels.

[0069] During operation, when the heat exchange device is started, the variable frequency compressor 2 drives the refrigerant to circulate within the circuit. The refrigerant flows through the first heat exchanger 3 and the second heat exchanger 4, allowing the first heat exchanger 3 and the second heat exchanger 4 to complete heat exchange respectively. The frame body 101, the base plate 102, and the reinforcing member 103 together provide installation support for the variable frequency compressor 2, the first heat exchanger 3, and the second heat exchanger 4, and can buffer the vibration generated by the operation of the equipment, reducing the transmission of vibration to external equipment.

[0070] The heat exchange device provided by the above technical solution can be directly applied to special vehicles or special ships to achieve heat dissipation. This heat exchange device integrates the variable frequency compressor 2, the first heat exchanger 3, and the second heat exchanger 4 within the frame body 101. Each component is integrated and installed using the frame body 101 and the base plate 102, reducing the external installation space occupied by each component and achieving integrated layout of the entire machine structure. The heat exchange device strengthens the frame body 101 with reinforcing members 103, making it less prone to deformation when subjected to vibrations and impacts from the compressor's operation, thus improving the structural stability of the entire machine. The heat exchangers within the device offer multiple optional fixed assembly methods, allowing for flexible selection of connection points based on site installation space and vibration conditions, broadening the device's practical assembly adaptability. By employing the variable frequency compressor 2, heat exchange can be achieved on demand, reducing energy consumption.

[0071] See also Figures 2 to 5 In some embodiments, the variable frequency compressor 2 is installed in the middle of the frame body 101, and the second heat exchanger 4 is located between the variable frequency compressor 2 and the first heat exchanger 3.

[0072] During the assembly process, the positions of each component are arranged in the internal space of the frame body 101, so that the variable frequency compressor 2 is located in the middle of the frame body 101, the second heat exchanger 4 is sandwiched between the variable frequency compressor 2 and the first heat exchanger 3, and the assembly gap between each component is reserved for the laying of heat exchange pipelines. After each component completes the corresponding fixing operation, the variable frequency compressor 2, the first heat exchanger 3, and the second heat exchanger 4 can be supported by the support component 1 and the base plate 102 respectively.

[0073] During use, the vibration load generated by the variable frequency compressor 2, which is located in the middle, can be transmitted to the base plate 102 and then to the main body of the support assembly 1, thereby dispersing the vibration generated by the operation of the variable frequency compressor 2. In addition, since the variable frequency compressor 2 is centrally located, pipelines can be connected to the second heat exchanger 4 and other pipeline interfaces from both sides of the variable frequency compressor 2, which facilitates the neat arrangement of pipelines.

[0074] The second heat exchanger 4 is positioned between the variable frequency compressor 2 and the first heat exchanger 3, enabling a compact arrangement of all components within the frame body 101, rationally allocating the internal space of the frame body 101, and reducing the overall volume occupied by the machine. The second heat exchanger 4's location between the variable frequency compressor 2 and the first heat exchanger 3 facilitates shortening the actual length of the connecting pipes between the three components, reducing resistance losses in the flow of the medium within the pipes, and also facilitates a neat arrangement of the pipes, reducing the probability of pipe entanglement and interference.

[0075] In some embodiments, the heat exchange device further includes an oil separator 5 and a gas-liquid separator 6. The oil separator 5 is installed inside the frame body 101. The gas-liquid separator 6 is installed inside the frame body 101. The oil separator 5, the gas-liquid separator 6, and the second heat exchanger 4 are arranged side-by-side.

[0076] Oil separator 5 and gas-liquid separator 6 are connected to the refrigerant circulation loop through refrigeration pipes. Oil separator 5, gas-liquid separator 6 and second heat exchanger 4 are fixed and constrained by the base plate 102 or the frame body 101, and are all installed in the internal space enclosed by the frame body 101.

[0077] The oil separator 5, gas-liquid separator 6, and second heat exchanger 4 are arranged side by side in the same direction, with clearances reserved between adjacent components for pipeline assembly and maintenance. After the positioning and fixing of each component are completed, pipeline connection work is carried out. The assembly stress and operating vibration generated by each component can be transmitted to the base plate 102 and the frame body 101.

[0078] The oil separator 5, gas-liquid separator 6, and second heat exchanger 4 are arranged side by side, making full use of the remaining space inside the frame body 101, resulting in a high degree of integration and a small size of the heat exchange device. The oil separator 5 and gas-liquid separator 6 are located close to the second heat exchanger 4, shortening the length of the connecting pipes and reducing pressure loss of the refrigerant within the pipes. The oil separator 5 separates the lubricating oil carried by the circulating medium, reducing the adverse effects of lubricating oil entering the heat exchanger and affecting heat exchange efficiency. The gas-liquid separator 6 prevents liquid medium from entering the variable frequency compressor 2, protecting the compressor. This side-by-side arrangement also simplifies later maintenance and repair procedures, reducing the difficulty of disassembly and assembly.

[0079] See Figure 1 During operation, when the heat exchange device starts running, the refrigerant discharged from the variable frequency compressor 2 flows through the oil separator 5, which separates the lubricating oil mixed inside the refrigerant. After processing, the refrigerant continues to flow along the loop, completing heat exchange in the first heat exchanger 3 before flowing into the second heat exchanger 4, and then into the gas-liquid separator 6. The gas-liquid separator 6 completes the gas-liquid two-phase separation of the refrigerant, allowing the gaseous medium to flow back to the variable frequency compressor 2 to participate in the cycle.

[0080] See Figure 8In some embodiments, the heat exchange device further includes an axial fan assembly 13, a fan mounting plate 14, and a fan fixing assembly 15. The axial fan assembly 13 is mounted on the top of the frame body 101. The fan mounting plate 14 is fixedly mounted on the top of the frame body 101. The fan mounting plate 14 includes mounting holes, in which at least a portion of the axial fan assembly 13 is located. The fan fixing assembly 15 includes multiple fixing rods, which are distributed dispersedly; one end of each fixing rod is fixedly connected to the fan mounting plate 14, and the other end of each fixing rod is fixedly connected to the axial fan assembly 13.

[0081] The axial fan assembly 13 is positioned through the mounting holes of the fan mounting plate 14, and then secured at multiple points by multiple distributed fixing rods. Specifically, the vibration load generated by the fan operation can be distributed and transmitted to the fan mounting plate 14 and the frame body 101 through multiple fixing rods. The heat exchange device has three-sided air inlet, and the airflow is discharged from the top of the unit after heat exchange through the condenser.

[0082] Specifically, the fan is fixed to the 8mm thick fan mounting plate 14 by four 5mm thick fixing rods, and the motor part, which is the heaviest part of the fan, is locked and fixed from four directions using bolts. At the same time, the fan mounting plate 14 is fastened to the top of the frame body 101 by bolts.

[0083] The aforementioned technical solution employs a multi-directional, high-strength, layered fixing method to reinforce the core heavy-load components of the fan at multiple points, significantly improving the installation rigidity and connection reliability of the axial flow fan. This enables the fan to exhibit excellent vibration resistance under conditions of overall machine vibration and bumps, effectively preventing fan loosening, displacement, abnormal noise, and structural failure. Furthermore, the axial flow fan assembly 13 is integrated into the top of the frame body 101, without occupying the installation space inside the support assembly 1. The multi-point fixing rods can evenly bear the vibration of the fan operation, reducing the risk of fan displacement and connection loosening, and improving the installation reliability of the fan assembly.

[0084] See Figure 9 and Figure 10In some embodiments, the heat exchange device further includes an electrical control box 7, a first corrugated pipe 8, a second corrugated pipe 9, and a third corrugated pipe 10. The electrical control box 7 is located inside the frame body 101 and at least partially contacts the inner wall of the frame body 101; the electrical control box 7 includes a heat dissipation assembly 701 and a housing 702, with the heat dissipation assembly 701 installed inside the housing 702. The heat dissipation assembly 701 includes a first heat dissipation plate 7011 and a second heat dissipation plate 7012 connected in series via the first corrugated pipe 8; the first heat dissipation plate 7011 is used to dissipate heat for the first circuit board a, and the second heat dissipation plate 7012 is used to dissipate heat for the second circuit board b. The housing 702 is provided with a first opening 7021 and a second opening 7022. One end of the first corrugated pipe 8 is connected to the outlet of the first heat dissipation plate 7011, and the other end of the first corrugated pipe 8 is connected to the inlet of the second heat dissipation plate 7012. The inlet of the second corrugated pipe 9 is connected to the cooling fluid outlet of the second heat exchanger 4, and the outlet of the second corrugated pipe 9 is connected to the inlet of the first heat dissipation plate 7011. The inlet of the third corrugated pipe 10 is connected to the outlet of the second heat sink 7012, and the outlet of the third corrugated pipe 10 is connected to the cooling fluid inlet of the second heat exchanger 4. The cooling fluid of the second heat exchanger 4 is the fluid that exchanges heat with the refrigerant inside the second heat exchanger 4. The second heat exchanger 4 acts as an evaporator, and the cooling fluid of the second heat exchanger 4 is cooled down by the refrigerant inside the second heat exchanger 4. After being cooled down, the cooling fluid of the second heat exchanger 4 enters the heat dissipation assembly 701 to cool the electronic components inside the electrical control box 7.

[0085] In addition, the flow rate of the cooling fluid in the second heat exchanger 4 may be greater than the flow rate required by the heat dissipation assembly 701. The cooling fluid in the second heat exchanger 4 can also be provided with an outflow branch 41 to discharge the portion of cooling fluid not needed by the heat dissipation assembly 701. Furthermore, the cooling fluid in the second heat exchanger 4 can also be provided with an inflow branch 42 to ensure that the flow rate of the cooling fluid in the second heat exchanger 4 meets the heat exchange requirements of the refrigerant circulation branch where the variable frequency compressor 2 is located.

[0086] The first corrugated pipe 8, the second corrugated pipe 9, and the third corrugated pipe 10 can absorb the vibration displacement generated by the equipment operation, reduce the alternating stress on the pipe interface, and improve the sealing reliability of the pipe connection. In addition, since the corrugated pipe has deformation compensation capability, it can adapt to the slight deviation of the assembly position. The vibration generated by the electrical control box 7 and the heat dissipation component 701 can be transmitted to the frame body 101, and the reinforcing member 103 continuously provides structural reinforcement to the frame body 101.

[0087] Compared to existing technologies, each flexible corrugated pipe is installed on the back of the electrical control box 7 and connected to the heat dissipation assembly 701 inside the electrical control box 7. Compared to the clamp-type heat dissipation assembly 701 cold plate used in traditional electrical control boxes 7, this invention arranges the cold plate of the heat dissipation assembly 701 inside the electrical control box 7, and no longer uses the copper pipe clamp installation method, which can avoid the risk of copper pipe breakage at the cold plate of the heat dissipation assembly 701 under high vibration conditions, thereby causing equipment failure.

[0088] The electrical control box 7 is integrated inside the frame body 101, eliminating the need for additional external installation space and allowing the entire machine to maintain a compact and integrated structure. The heat dissipation component 701 effectively dissipates heat from the internal components of the electrical control box 7, reducing or even preventing heat accumulation inside the box.

[0089] In the above embodiments, the support component 1 is made of high-strength hot-rolled steel plate with an anti-corrosion coating. The internal vibration-damping supports, such as the compressor fixing component 11, the heat exchanger fixing component 12, the fan fixing component 15, and the electrical control box 7, are all made of SUS316 steel plate and are also treated with an anti-corrosion coating.

[0090] By combining the above materials and coatings, the heat exchange device can achieve waterproof protection in complex working conditions such as high humidity, high salinity, and dust, and has excellent corrosion resistance, which improves the service life of the whole machine in harsh environments and avoids the problems of easy rusting and failure of traditional systems.

[0091] The assembly process of the heat exchanger is as follows: First, the core components, such as the finned condenser, plate evaporator, variable frequency compressor 2, gas-liquid separator 6, and oil separator 5, are sequentially assembled and placed on the base plate 102. Then, the components are connected by welding copper pipes to complete the construction of the overall cooling flow path. After the cooling flow path is welded, the support assembly 1 is fitted onto the outside of the base plate 102 from top to bottom. The base plate 102 has sixteen pre-reserved mounting bolt positions. After the support assembly 1 is in place, the corresponding nuts are tightened to achieve the fixed assembly of the frame body 101 and the base plate 102. Finally, the axial flow fan is fixedly installed on the top of the support assembly 1 with bolts, so that all components cooperate to form an integrated structure, thereby completing the overall assembly of the liquid-cooled heat exchanger.

[0092] The control process of the aforementioned heat exchange device is as follows: High-pressure sensor 16, low-pressure sensor 17, suction temperature sensor 18, and exhaust temperature sensor 19 can collect system pressure and ambient temperature data in real time. The main control AI chip accurately calculates the heat dissipation load based on the real-time ambient temperature and outputs frequency conversion adjustment commands to the variable frequency compressor 2 and the axial flow fan, respectively. At the same time, the main control chip outputs control commands to adjust the regulating valve 301 set on the first branch of the finned condenser to accurately control the refrigerant flow. Through the coordinated control of multiple components, the heat exchange device maintains a highly efficient and energy-saving operating state under various complex working conditions and has high-precision temperature control capabilities.

[0093] The aforementioned technical solution involves a rational layout of core components such as the variable frequency compressor 2 and the plate evaporator, and a meticulously planned and designed internal piping system according to manufacturing limits. All components and parts of the unit adopt a modular design, allowing for independent disassembly and replacement of each functional unit, significantly improving the convenience of equipment inspection and maintenance. Simultaneously, this structural design fully utilizes the limited internal space of the unit, effectively reducing the overall volume and meeting the stringent design requirements for miniaturization and lightweight liquid-cooled heat exchangers. The overall dimensions are only 970×970×1500mm. Under ambient temperature conditions of 45℃, the measured cooling capacity of the heat exchanger can reach 80KW, achieving both compactness and lightweight design while also providing excellent high-power heat dissipation and cooling performance.

[0094] This invention also provides a transport device, including the heat exchange device provided by any of the technical solutions of this invention. The transport device may be, for example, a special vehicle, an unmanned aerial vehicle platform, a deep-sea work vessel, or a high-speed patrol boat.

[0095] The heat exchanger, through its vibration-resistant structure, corrosion protection, and variable-condition heat exchange adjustment capabilities, can adapt to complex operating conditions such as bumps, vibrations, high humidity, and high salt spray during the operation of the transport equipment, providing stable heat dissipation for the internal heat-generating components of the transport equipment. The heat exchanger is energy-saving, robust, vibration-resistant, easy to maintain, compact in structure, and occupies little installation space.
