Description

Technical Field

[0001] The present invention relates to the technical field of servers, and in particular to a heat exchanger installation device and a hydraulic system. Background Art

[0002] Related technologies point out that the secondary-side CDU (Cooling Distribution Unit) of a liquid-cooled server heat dissipation system is a key component. A plate heat exchanger works with the CDU in the secondary-side circuit, transferring server heat to the coolant via the cold plate, where the heat exchanger ultimately completes the heat exchange. Plate heat exchangers weigh over 75 kg, with the heaviest currently weighing 150 kg. They also lack handles or other lifting aids, making manual installation into the CDU difficult. Existing gantry cranes are large, occupy a large area, and are inconvenient for operators to stand underneath. The lifting wires cannot be rigidly positioned. Mobile gantry cranes have poor stability and limited load capacity. Gantry crane ground rails are prone to potential hazards and require regular maintenance and corrosion protection, otherwise their lifespan is affected. Pneumatic balance cranes, due to the compressibility of air, have poor stability under varying loads and produce high exhaust noise. While they enable human-machine collaboration, they lack operational flexibility, low operating pressure, limited structural dimensions, low output power, and positioning accuracy compared to intelligent cranes. Their limited suspension height also makes the plate heat exchanger incompatible with cabinets and CDUs of varying heights. Summary of the Invention

To this end, the present invention provides a heat exchanger installation device that allows operators to position and install the heat exchanger without having to lift heavy objects. Furthermore, the operator can adjust the height of the heat exchanger according to the height of the cabinet, thereby reducing the installation difficulty for the operator and improving operational flexibility and safety.

[0008] In the above technical solution, the first locking portion and the second locking portion cooperate to realize the switching of the fixing assembly between the locked state and the unlocked state, thereby achieving stable support for the heat exchanger and flexible release of the mounting plate.

[0061] In the description of the embodiments of the present invention, the term "plurality" refers to more than two (including two).

[0062] Related technologies point out that the secondary-side CDU (Cooling Distribution Unit) of a liquid-cooled server heat dissipation system is a key component. A plate heat exchanger works with the CDU in the secondary-side circuit, transferring server heat to the coolant via the cold plate, where the heat exchanger ultimately completes the heat exchange. Plate heat exchangers weigh over 75 kg, with the heaviest currently weighing 150 kg. They also lack handles or other lifting aids, making manual installation into the CDU difficult. Existing gantry cranes are large, occupy a large area, and are inconvenient for operators to stand underneath. The lifting wires cannot be rigidly positioned. Mobile gantry cranes have poor stability and limited load capacity. Gantry crane ground rails are prone to potential hazards and require regular maintenance and corrosion protection, otherwise their lifespan is affected. Pneumatic balance cranes, due to the compressibility of air, have poor stability under varying loads and produce high exhaust noise. While they enable human-machine collaboration, they lack operational flexibility, low operating pressure, limited structural dimensions, low output power, and positioning accuracy compared to intelligent cranes. Their limited suspension height also makes the plate heat exchanger incompatible with cabinets and CDUs of varying heights. Therefore, how to transport and install plate heat exchangers more flexibly and efficiently has become an issue that needs to be solved urgently.

[0063] Based on the above considerations, in order to more flexibly and efficiently transport and install the plate heat exchanger, the inventor has designed a heat exchanger installation device after in-depth research. Figures 1-6 A heat exchanger mounting apparatus according to an embodiment of a first aspect of the present invention will be described.

[0064] like Figures 1-6 As shown, Figure 1 A schematic diagram of a heat exchanger installation device according to an embodiment of the present invention; Figure 2 A schematic diagram of a heat exchanger installation device according to an embodiment of the present invention; Figure 3 for Figure 2 A schematic diagram of the fixing assembly shown in ; Figure 4 for Figure 3 Schematic diagram of the mounting plate shown in ; Figure 5 is a schematic diagram of a hydraulic system according to an embodiment of the present invention; Figure 6 This is an electrical control principle diagram of an embodiment of the present invention.

[0065] The heat exchanger installation device 100 according to the first embodiment of the present invention includes: a platform 1 and a fixing assembly 2 .

[0066] Specifically, the platform 1 is movable in the up and down directions, the fixing component 2 is arranged on the platform 1, the fixing component 2 includes a mounting plate 21, the heat exchanger 300 is suitable for being arranged on the mounting plate 21, and the fixing component 2 can be switched between a locked state and an unlocked state. When the fixing component 2 is in the locked state, the mounting plate 21 is completely located above the platform 1. When the fixing component 2 is in the unlocked state, the mounting plate 21 can move toward the outside of the platform 1 so that the heat exchanger 300 is located outside the platform 1. Therefore, the platform 1 can be adjusted in the up and down directions, so that it can be adjusted to a suitable height according to actual needs, which is convenient for the operator to install the heat exchanger 300. When the fixing component 2 is in the locked state, the mounting plate 21 is completely located above the platform 1, ensuring that the heat exchanger 300 is stable and does not fall during transportation. When the fixing component 2 is switched to the unlocked state, the mounting plate 21 can be moved to the outside of the platform 1, so that the heat exchanger 300 can be close to and connected to the cabinet. The operator adjusts the position of the heat exchanger 300 according to the height of the cabinet, and the operator can complete the positioning and installation of the heat exchanger 300 without lifting heavy objects, which improves the flexibility and safety of the operation, reduces the risks that may be brought to the operator by manual handling, and improves work efficiency and installation quality.

[0067] It is understandable that if Figure 1 and Figure 2As shown, the platform 1 is the basic bearing structure for mounting the equipment 100 for carrying the heat exchanger 300. The platform 1 has an ascending and descending motion, that is, the platform 1 can be raised and lowered in the vertical direction, so that the operator can adjust the height position of the heat exchanger 300 according to the height of the cabinet. The fixing component 2 is fixed on the platform 1 for fixing the heat exchanger 300. The fixing component 2 includes a mounting plate 21. The mounting plate 21 is used to directly carry the heat exchanger 300. The mounting plate 21 can move outward relative to the platform 1 in the horizontal direction. When the fixing component 2 is in a locked state, the mounting plate 21 It is completely located above the platform 1. At this time, the heat exchanger 300 is also completely located above the platform 1. In this way, when the installation equipment 100 is moved, the heat exchanger 300 is prevented from falling from the platform 1 to the ground and causing damage to the heat exchanger 300. When the fixing component 2 is switched from the locked state to the unlocked state, the mounting plate 21 can move toward the outside of the platform 1. At this time, the heat exchanger 300 follows the mounting plate 21 and moves toward the outside of the platform 1. When the heat exchanger 300 is positioned with the cabinet, the heat exchanger 300 extends beyond the outer peripheral side of the platform 1 and is located outside the platform 1, which is convenient for the operator to assemble the heat exchanger 300 with the cabinet.

[0068] According to the heat exchanger installation device 100 of the embodiment of the present invention, by providing a liftable platform 1, the operator can adjust the height position of the heat exchanger 300 according to the height of the cabinet. The operator can complete the positioning and installation of the heat exchanger 300 without lifting heavy objects. In this way, one person can complete the entire process of hoisting, positioning and installation, which reduces the difficulty of installing the heat exchanger 300 for the operator, improves the flexibility and safety of the operation, reduces the risks that may be brought about by manual handling by the operator, and improves work efficiency and installation quality.

[0069] In any embodiment of the present invention, the fixing assembly 2 further includes: a base plate 22 and a locking unit 23. The base plate 22 is fixedly connected to the platform 1. The locking unit 23 is disposed between the base plate 22 and the mounting plate 21. The locking unit 23 includes a first locking portion and a second locking portion. The first locking portion is disposed on the base plate 22, and the second locking portion is disposed on the mounting plate 21. The mounting plate 21 and the base plate 22 are locked together by the first locking portion and the second locking portion. When the fixing assembly 2 is in an unlocked state, the first locking portion is separated from the second locking portion. When the fixing assembly 2 is in a locked state, the first locking portion and the second locking portion are in contact. Thus, the first locking portion and the second locking portion cooperate to enable the fixing assembly 2 to switch between a locked state and an unlocked state, thereby achieving stable support for the heat exchanger 300 and flexible release of the mounting plate 21. In this way, in the locked state, the heat exchanger 300 can be prevented from falling during movement, causing accidents and losses.

[0070] It can be understood that a first locking portion is provided on the base plate 22, and a second locking portion is provided on the mounting plate 21. The first locking portion cooperates with the second locking portion so that the fixing assembly 2 switches between a locked state and an unlocked state. The mounting plate 21 and the base plate 22 move relative to each other, and the first locking portion and the second locking portion are separated from each other, so that the fixing assembly 2 switches from a locked state to an unlocked state. Alternatively, the mounting plate 21 and the base plate 22 move relative to each other, and the first locking portion and the second locking portion are separated from each other and contacted with each other, so that the fixing assembly 2 switches from an unlocked state to a locked state. The locking unit 23 is modularly designed for easy replacement and maintenance. The locking unit 23 ensures the safety of the heat exchanger 300 during movement and avoids damage to the heat exchanger 300.

[0071] Furthermore, the locking unit 23 includes: a locking block 231 and a locking hook 232. The locking block 231 is arranged on the base plate 22, and the locking hook 232 is arranged on the mounting plate 21. The locking block 231 is formed as a first locking part, and the locking hook 232 is formed as a second locking part. The locking block 231 is located in the locking hook 232, and the mounting plate 21 and the base plate 22 are locked by the locking block 231 and the locking hook 232. Therefore, by setting the locking block 231 and the locking hook 232, the locking block 231 is arranged on the base plate 22 and the locking hook 232 is arranged on the mounting plate 21. When the fixing component 2 is in the locked state, the locking hook 232 is engaged with the outside of the locking block 231, thereby realizing the locking between the mounting plate 21 and the base plate 22. When the fixing component 2 is unlocked, the locking block 231 is disengaged from the locking hook 232, so that the mounting plate 21 can slide relative to the base plate 22. The locking hook 232 and the locking block 231 are fixed by a mechanical structure and are not easy to loosen after locking. The fixing component 2 is stable, reliable and highly safe in the locked state.

[0072] Reference Figure 3 As shown, it can be understood that the locking block 231 is fixed to the base plate 22, and the locking hook 232 is provided on the mounting plate 21. When the fixing assembly 2 is in the unlocked state, the locking hook 232 separates from the locking block 231, allowing the mounting plate 21 to slide or move outward relative to the base plate 22. The locking unit 23 has a simple structure, low production cost, and is stable and reliable. In addition, when the fixing assembly 2 is in the locked state, the locking block 231 is enclosed by the locking hook 232, forming a stable connection. At this time, the mounting plate 21 is completely above the base plate 22 and cannot move horizontally, effectively preventing the heat exchanger 300 from shifting or falling.

[0073] Furthermore, a first guide surface is formed on the locking block 231 , and a second guide surface is formed on the locking hook 232 . The first guide surface cooperates with the second guide surface for guidance. The locking hook 232 is provided with an elastic member, which has a force that connects the locking hook 232 to the locking block 231 . The second guide surface is formed on the locking block 231, and the second guide surface is formed on the locking hook 232. During the sliding of the mounting plate 21, the first guide surface of the locking block 231 contacts the second guide surface on the locking hook 232, and the guiding locking block 231 is wrapped by the locking hook 232 to complete the locking action. In this way, the operator can complete the locking without precise alignment, the operation difficulty is low, and the assembly efficiency of the operator is improved; the elastic member provides a force to keep the locking hook 232 in contact with the locking block 231 at all times, which can prevent accidental unlocking caused by vibration or slight displacement, reduce the risk of accidental unlocking due to external interference, and enhance the locking stability of the fixing component 2.

[0074] In some feasible embodiments, a proximity switch or a pressure sensor may be provided on the locking hook 232 or the locking block 231 to detect in real time whether the locking hook 232 and the locking block 231 are locked in place, thereby improving the reliability of the locking unit 23 .

[0075] In any embodiment of the present invention, the fixing assembly 2 further includes a positioning unit 24, which is disposed between the base plate 22 and the mounting plate 21. The positioning unit 24 includes a first positioning portion and a second positioning portion. The first positioning portion is disposed on the base plate 22, and the second positioning portion is disposed on the mounting plate 21. The mounting plate 21 and the base plate 22 are positioned by the first positioning portion and the second positioning portion. When the fixing assembly 2 is in an unlocked state, the first positioning portion is separated from the second positioning portion. When the fixing assembly 2 is in a locked state, the first positioning portion and the second positioning portion contact each other to position the base plate 22 relative to the mounting plate 21. Thus, the first positioning portion and the second positioning portion cooperate to securely lock the relative position between the mounting plate 21 and the base plate 22, thereby achieving more stable support for the heat exchanger 300 and precise positioning between the base plate 22 and the mounting plate 21. Thus, the positioning unit 24 cooperates with the locking unit 23. In the locked state, the heat exchanger 300 can be effectively prevented from falling during movement, causing accidents and losses.

[0076] It can be understood that a first positioning portion is provided on the bottom plate 22, and a second positioning portion is provided on the mounting plate 21. The first positioning portion cooperates with the second positioning portion so that when the fixing assembly 2 is in the locked state, the mounting plate 21 and the bottom plate 22 will not be displaced relative to each other, and the relative position between the mounting plate 21 and the bottom plate 22 is more stable. The mounting plate 21 and the bottom plate 22 move relative to each other, and the first positioning portion and the second positioning portion contact each other and separate from each other. At the same time, the first locking portion and the second locking portion contact each other and separate from each other, so that the fixing assembly 2 switches from the locked state to the unlocked state, or the mounting plate 21 and the bottom plate 22 move relative to each other. The plate 22 moves relative to each other, the first positioning portion and the second positioning portion are separated from each other and then contacted with each other, and the first locking portion and the second locking portion are separated from each other and then contacted with each other, so that the fixing assembly 2 switches from the unlocked state to the locked state, and the fixing unit and the locking unit 23 cooperate with each other. After the locking block 231 is located in the locking hook 232, the first positioning portion contacts the second positioning portion, which improves the precise positioning between the mounting plate 21 and the base plate 22, limits the displacement between the base plate 22 and the mounting portion in multiple directions, reduces the wear of the locking unit 23, and prevents damage to the locking hook 232 or the locking block 231 caused by misalignment.

[0077] Furthermore, the positioning unit 24 includes: a positioning block 241 and a positioning pin 242. The positioning block 241 is arranged on the base plate 22. The positioning block 241 is formed with a positioning hole, which is formed as a first positioning portion. The positioning pin 242 is arranged on the mounting plate 21. The mounting plate 21 is formed with a through hole. The positioning pin 242 can be movably arranged in the through hole. The positioning pin 242 is formed with a positioning column, which is formed as a second positioning portion. The positioning column passes through the through hole and extends into the positioning hole. The mounting plate 21 and the base plate 22 are positioned by the positioning pin 242 and the positioning block 241. Therefore, by setting the positioning block 241 and the positioning pin 242, the first positioning portion is formed as a positioning hole, and the second positioning portion is formed as a positioning column, which extends into the positioning hole to realize the positioning between the mounting plate 21 and the base plate 22. When the fixing assembly 2 is in the locked state, the positioning column is located in the positioning hole, limiting the displacement of the mounting plate 21 and the base plate 22 in multiple directions, forming a rigid limit. When the fixing assembly 2 is unlocked, the positioning column disengages from the positioning hole, and at the same time, the locking block 231 disengages from the locking hook 232, so that the mounting plate 21 can slide relative to the base plate 22. That is, through the cooperation between the positioning block 241 and the positioning pin 242 and the cooperation between the locking block 231 and the locking hook 232, the displacement between the base plate 22 and the mounting portion in multiple directions is limited, effectively improving the stability and reliability of the fixing assembly 2 in the locked state.

[0078] Reference Figure 3As shown, the positioning block 241 is arranged on the base plate 22, the positioning hole is formed on the positioning block 241, the positioning pin 242 is arranged on the mounting plate 21, and a through hole is formed on the mounting plate 21. The positioning pin 242 is movably arranged in the through hole, and the positioning pin 242 is formed with a positioning column. The first positioning portion is formed as a positioning hole, and the second positioning portion is formed as a positioning column. When the fixing component 2 is in a locked state, the locking hook 232 is engaged with the outside of the locking block 231, and the positioning column passes through the through hole and extends into the positioning hole. No relative displacement can be generated between the mounting plate 21 and the base plate 22. When the fixing component 2 is unlocked, the locking block 231 disengages from the locking hook 232, and the positioning column disengages from the positioning hole, so that the mounting plate 21 can slide relative to the base plate 22.

[0079] In any embodiment of the present invention, the fixing assembly 2 further includes a sliding unit 25, which is disposed between the mounting plate 21 and the base plate 22. The sliding unit 25 includes a first sliding portion and a second sliding portion. The first sliding portion is disposed on the base plate 22, and the second sliding portion is disposed on the mounting plate 21. The mounting plate 21 and the base plate 22 are slidably connected relative to each other via the first positioning portion and the second positioning portion. Thus, the first and second sliding portions cooperate to achieve smooth relative movement between the mounting plate 21 and the base plate 22. The first and second sliding portions reduce friction between the mounting plate 21 and the base plate 22. Furthermore, the first and second sliding portions cooperate to guide the relative movement of the mounting plate 21 and the base plate 22, ensuring the balance and stability of the heat exchanger 300 during movement.

[0080] Further, refer to Figure 3 As shown, the sliding unit 25 includes: a guide rail 251 and a slider 252. The guide rail 251 is arranged on the base plate 22. The first sliding part is formed as the guide rail 251. The slider 252 is arranged on the mounting plate 21. The second sliding part is formed as the slider 252. The slider 252 and the guide rail 251 are slidable relative to each other. The mounting plate 21 is connected to the base plate 22 for relative sliding through the guide rail 251 and the slider 252. When the fixing component 2 switches from the unlocked state to the locked state, the mounting plate 21 moves toward the inner side of the platform 1, and the mounting plate 21 and the base plate 22 slide relative to each other. The slider 252 slides along the length direction of the guide rail 251, which not only provides a guide for the sliding of the mounting plate 21, but also reduces the friction generated when the mounting plate 21 and the base plate 22 slide relative to each other.

[0081] Furthermore, it can be understood that a sliding groove can be formed on the side of the slider 252 facing the guide rail 251, and the sliding groove wraps the circumference of the guide rail 251, thereby avoiding separation between the slider 252 and the guide rail 251, ensuring that the sliding unit 25 can work stably, and further improving the stability and reliability of the fixed component 2.

[0082] In any embodiment of the present invention, the fixing assembly 2 further includes a guide unit 26, which is disposed between the mounting plate 21 and the base plate 22. The guide unit 26 includes a first guide portion and a second guide portion, wherein the first guide portion is disposed on the base plate 22, and the second guide portion is disposed on the mounting plate 21. The mounting plate 21 and the base plate 22 are guided by the cooperation of the first guide portion and the second guide portion. Thus, the first guide portion and the second guide portion cooperate to guide the movement direction of the mounting plate 21, thereby preventing deviation or jamming, and improving the stability and safety of the mounting plate 21 during movement relative to the base plate 22. The guide unit 26 cooperates with the sliding unit 25 to reduce friction between the mounting plate 21 and the base plate 22 during relative movement, while preventing lateral deviation or tilting of the mounting plate 21 and the base plate 22 during relative movement, further ensuring the balance and stability of the heat exchanger 300 during movement.

[0083] Reference Figure 3 As shown, in a feasible embodiment, the guide unit 26 includes: a guide shaft 261, a guide block 262 and a buffer 263. The guide block 262 is formed with a guide hole. The guide shaft 261 is inserted into the guide hole. The guide block 262 is movable along the axial direction of the guide shaft 261. The guide shaft 261 is formed as a first guide portion, and the guide hole is formed as a second guide portion. The mounting plate 21 and the base plate 22 are guided by the guide shaft 261 and the guide block 262. The buffer 263 is sleeved on both ends of the guide shaft 261. When the fixing assembly 2 switches from the unlocked state to the locked state, the mounting plate 21 moves toward the inner side of the platform 1, and the mounting plate 21 and the base plate 22 are connected. The plates 22 slide relative to each other, the slider 252 slides along the length direction of the guide rail 251, and the guide block 262 slides along the axial direction of the guide shaft 261, guiding the mounting plate 21 during the sliding process of the mounting plate 21. The guide rail 251 cooperates with the slider 252 and the guide shaft 261 cooperates with the guide block 262 to guide the mounting plate 21 while it slides relative to the base plate 22, and buffer parts 263 are provided at both ends of the guide shaft 261 to absorb impact energy when the mounting plate 21 slides to the extreme positions at both ends of the guide shaft 261, prevent hard collisions, avoid structural damage, and extend the service life of the mounting device 100.

[0084] In any embodiment of the present invention, Figure 4As shown, the mounting plate 21 includes a base plate 211, a fixing plate 212, and a support plate 213. The fixing plate 212 and the base plate 211 are arranged perpendicular to each other and connected to each other. The support plate 213 is connected between the base plate 211 and the fixing plate 212. The fixing plate 212 is formed with a plurality of mounting holes 214, at least some of which are formed as elongated holes. Thus, the provision of the support plate 213 strengthens the overall structural rigidity of the mounting plate 21, improving the bending resistance and stability of the mounting plate 21 when subjected to heavy loads. Furthermore, the formation of the plurality of mounting holes 214 on the fixing plate 212, formed as elongated holes, provides horizontal or vertical adjustment space for the heat exchanger 300, facilitating adaptation to the installation position of different models of heat exchangers 300.

[0085] Reference Figure 4 As shown, there are eight mounting holes 214, and the eight mounting holes 214 are all formed as long strip holes, and the size of at least two mounting holes 214 of the eight mounting holes 214 is different from the size of the other mounting holes 214. In this way, the installation of various types of heat exchangers 300 can be achieved, which improves the applicability of the installation equipment 100. A wear-resistant part 5 is provided under the mounting plate 21, and the wear-resistant part 5 is connected to the bottom plate 22. The wear-resistant part 5 protects the appearance of the heat exchanger 300 product and avoids damage to the appearance of the heat exchanger 300. A pulling handle 27 is provided on the mounting plate 21, which is convenient for pushing and pulling the mounting plate 21.

[0086] In any embodiment of the present invention, the heat exchanger installation device 100 further includes: a lifting mechanism 3 and a base 4. The lifting mechanism 3 is provided between the base 4 and the platform 1. The lifting mechanism 3 includes: a transmission assembly and a drive assembly. The drive assembly is connected to the platform 1 via the transmission assembly and is used to drive the platform 1 to move in the up and down directions. It can be understood that the base 4 is the basic supporting structure of the entire device. The vertical movement of the platform 1 is achieved by providing the lifting mechanism 3. The lifting mechanism 3 includes a transmission assembly and a drive assembly. The transmission assembly is connected between the platform 1 and the base 4. The upper end of the transmission assembly is connected to the platform 1, and the lower end of the transmission assembly is connected to the base 4. The drive assembly is in transmission connection with the transmission assembly. The drive assembly can drive the transmission assembly to drive the platform 1 to move upward or downward.

[0087] In some embodiments, the transmission assembly includes a plurality of linkage groups, each linkage group includes a first linkage rod and a second linkage rod, the first linkage rod and the second linkage rod are rotatably connected relative to each other, the two ends of the first linkage rod are respectively connected to one end of the second linkage rod of an adjacent linkage group, and the two ends of the second linkage rod are respectively connected to one end of the first linkage rod of an adjacent linkage group. Figure 1 and Figure 2As shown, multiple linkage groups are formed into a scissor-fork structure with multiple hinge points for evenly distributing the load, so that a single hinge point bears less pressure, thereby enhancing the overall load-bearing capacity, providing multi-point support, and increasing the stability of the platform 1. When not in use, the scissor-fork structure can be completely folded, taking up very little space, and is easy to place and transport.

[0088] In some embodiments, the driving assembly includes a cylinder and a piston. The piston is movably disposed in the cylinder. Hydraulic oil enters the cylinder to adjust the stroke of the piston.

[0089] In any embodiment of the present invention, the heat exchanger installation device 100 further includes a lifting electrical control system, which includes a drive module and a control module. The drive module is used to drive the lifting mechanism 3 upward and downward. The control module is connected to the drive module and is used to receive operating instructions to control the operating state of the drive module, including operating speed and direction. This enables precise adjustment of the lifting direction and speed, improves control flexibility, and thus enhances the intelligence of the installation device 100.

[0090] Furthermore, the drive module includes a drive pump 205 and a starting capacitor. The first phase of the drive pump 205 is connected to the neutral line, the second phase of the drive pump 205 is connected to the power input line, one end of the starting capacitor is connected to the third phase of the drive pump 205, and the other end of the starting capacitor is connected to the second phase of the drive pump 205. Thus, the provision of the starting capacitor improves the starting characteristics of the drive pump 205, enabling the drive pump 205 to obtain sufficient torque to overcome resistance in a static state at a relatively low starting current. This results in a low failure rate, ease of maintenance, low production costs, and strong adaptability.

[0091] In some embodiments, the heat exchanger installation device 100 also includes: a pushing handle 6, a moving component and a foot switch 9. The pushing handle 6 is connected to the base 4. The moving component includes two fixed wheels 7 and two universal wheels 8, which are convenient for moving the installation device 100 or moving the heat exchanger 300 to the cabinet. The foot switch 9 can be divided into an up switch and a down switch, which respectively control the up and down of the platform 1.

[0092] like Figure 6As shown, the lifting electrical control system includes a control circuit, which includes: a main circuit and a control circuit.

[0098] In other embodiments, the platform 1 can be raised to the approximate height of the connection pipe interface of the liquid cooling server cabinet, the lock hook 232 and the positioning pin 242 can be released, and the mounting plate 21 and the heat exchanger 300 can be pushed out. When the heat exchanger 300 is pushed out, the state of the installation device 100 is as follows: Figure 1 As shown. At this point, push the handle 6 to adjust the horizontal position via the universal wheel 8, and use the remote control to adjust the vertical position, ultimately completing precise positioning in three directions. During fine adjustment in the Z direction, if a person stands between the installation device 100 and the server cabinet and cannot operate the foot switch 9, the remote control can be used to raise and lower the platform 1.

[0099] According to the hydraulic system 200 of the second embodiment of the present invention, it is applied to the installation equipment 100 of the heat exchanger according to the first embodiment of the present invention. The hydraulic system 200 includes: a main passage 201, a reflux passage 202 and an overflow passage 203. The main passage 201 has a main oil inlet end and a main oil outlet end. The main oil inlet end is connected to the oil tank 204, and the main oil outlet end is connected to the drive component of the installation equipment 100. A drive pump 205 and a one-way valve 206 are connected in series on the main passage 201. A filter 209 is provided downstream of the oil tank 204. The reflux passage 202 has a reflux oil inlet end and a reflux oil outlet end. The reflux oil inlet end is connected between the main oil outlet end and the one-way valve 206, and the reflux oil outlet end is connected to the main oil inlet end. The overflow passage 203 has an overflow oil inlet end and an overflow oil outlet end. The overflow oil inlet end is connected between the drive pump 205 and the one-way valve 206, and the overflow oil outlet end is connected to the main oil inlet end.

[0100] When the hydraulic system 200 is working, hydraulic oil is first sucked in from the oil tank 204, purified by the filter 209, and then enters the drive pump 205 for pressurization. The pressurized hydraulic oil enters the main passage 201 through the one-way valve 206 and flows to the drive component (such as the hydraulic cylinder), pushing the platform 1 to rise or perform an action. After the drive component completes the action, the hydraulic oil returns to the main passage 201 through the reflux passage 202. A throttle valve can be set in the reflux path to adjust the speed, or a reversing valve can be used to change the direction of movement. When the system pressure exceeds the set value, the overflow valve 208 opens, and the excess hydraulic oil returns to the main oil inlet end through the overflow passage 203 to avoid damage to the system due to overpressure.

[0101] According to the hydraulic system 200 of the embodiment of the present invention, multiple protections are provided by setting up the overflow valve 208, the one-way valve 206 and the filter 209 to ensure stable operation of the system. The division of labor of each path is clear, which facilitates system design and maintenance. The reflux path 202 reduces energy loss and improves overall efficiency.

[0102] The following will refer to Figures 1-6 A heat exchanger mounting apparatus 100 according to a specific embodiment of the present invention is described.

[0103] like Figure 1-Figure 4As shown, the radiator installation device 100 includes: a platform 1, a fixing component 2, a lifting mechanism 3, a base 4 and a lifting electrical control system, and the fixing component 2 includes: a mounting plate 21, a base plate 22, a locking unit 23, a positioning unit 24, a sliding unit 25, a guide unit 26, a pushing handle 6, a directional wheel 7, a universal wheel 8, an up switch, a down switch and a hydraulic system 200.

[0104] Specifically, the platform 1 is the basic bearing structure of the installation equipment 100 for carrying the heat exchanger 300. The platform 1 has an ascending and descending motion, that is, the platform 1 can be raised and lowered in the vertical direction, which is convenient for the operator to adjust the height position of the heat exchanger 300 according to the height of the cabinet; the fixing component 2 is fixed on the platform 1 for fixing the heat exchanger 300. The fixing component 2 includes a mounting plate 21. The mounting plate 21 is used to directly carry the heat exchanger 300. The mounting plate 21 can move outward relative to the platform 1 in the horizontal direction. When the fixing component 2 is in a locked state, the mounting plate 2 1 is completely above the platform 1, and the heat exchanger 300 is also completely above the platform 1. This prevents the heat exchanger 300 from falling from the platform 1 to the ground and causing damage to the heat exchanger 300 when the installation device 100 is moved. When the fixing assembly 2 switches from the locked state to the unlocked state, the mounting plate 21 can move outward from the platform 1. At this time, the heat exchanger 300 follows the mounting plate 21 toward the outside of the platform 1. After the heat exchanger 300 is positioned with the cabinet, the heat exchanger 300 extends beyond the outer periphery of the platform 1 and is located outside the platform 1, making it easier for operators to assemble the heat exchanger 300 with the cabinet. The lifting mechanism 3 is located between the base 4 and the platform 1. The lifting mechanism 3 enables the vertical movement of the platform 1. The multiple linkage groups form a scissor-fork structure with multiple hinge points for evenly distributing the load. This reduces the pressure on each hinge point, enhances the overall load-bearing capacity, provides multi-point support, and increases the stability of the platform 1. When not in use, the scissor-fork structure can be completely folded, occupying a very small space, making it easy to store and transport.

[0105] The locking unit 23 comprises a locking block 231 and a locking hook 232. The locking block 231 is fixed to the base plate 22, and the locking hook 232 is mounted on the mounting plate 21. When the fixing assembly 2 is unlocked, the locking hook 232 separates from the locking block 231, allowing the mounting plate 21 to slide or move outward relative to the base plate 22. The locking unit 23 has a simple structure, low production cost, and is stable and reliable. Furthermore, when the fixing assembly 2 is locked, the locking block 231 is enclosed by the locking hook 232, forming a secure connection. At this point, the mounting plate 21 is completely above the base plate 22 and cannot move horizontally, effectively preventing the heat exchanger 300 from shifting or falling.

[0106] The positioning unit 24 includes: a positioning block 241 and a positioning pin 242. The positioning block 241 is provided on the base plate 22.
