Description

Technical Field

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

[0002] It is pointed out in the related art that the secondary-side CDU (Cooling Distribution Unit) of the liquid-cooled server cooling system is a key component. The plate heat exchanger cooperates with the CDU in the secondary-side circulation, transfers the heat of the server to the coolant through the cold plate, and finally completes the heat exchange by the plate heat exchanger. The weight of the plate heat exchanger is more than 75 kg, and the heaviest one currently reaches 150 kg. Moreover, there is no auxiliary lifting structure such as a lifting handle on the surface, and it is difficult to install it manually on the CDU. The existing gantry crane on the market has large structural dimensions and a large floor area, and it is not convenient for people to stand below to operate. The hoisting wire cannot be rigidly positioned. The mobile gantry crane has poor stability and limited load-carrying capacity. The ground track of the gantry crane is prone to hidden dangers and requires regular maintenance and anti-corrosion treatment, otherwise it will affect the service life. The pneumatic balance crane has poor stability when the load changes due to the compressibility of air, and the exhaust noise is large. Although it can cooperate with people, its operation flexibility is not high, the working pressure is low, the structural dimensions are limited, the output power is small, the positioning accuracy is not as good as that of the intelligent crane, the suspension height is limited, and the compatibility with the plate heat exchanger for cabinets and CDUs of different heights is poor. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. For this reason, the present invention provides an installation device for a heat exchanger, which enables an operator to complete the positioning and installation of the heat exchanger without lifting heavy objects. At the same time, the operator can adjust the height position of the heat exchanger according to the height of the cabinet, reducing the difficulty of the operator in installing the heat exchanger and improving the flexibility and safety of the operation.

[0004] The present invention also provides a hydraulic system.

[0005] According to the installation device for a heat exchanger of the first aspect of the present invention, the installation device includes: a platform that is movable in the vertical direction; a fixing component provided on the platform, the fixing component including a mounting plate, the heat exchanger being adapted to be provided on the mounting plate, the fixing component being switchable between a locked state and an unlocked state. When the fixing component is in the locked state, the mounting plate is completely located above the platform. When the fixing component is in the unlocked state, the mounting plate can move towards the outside of the platform so that the heat exchanger is located outside the platform.

[0006] The installation device of the heat exchanger according to the present invention is provided with a liftable platform, enabling the operator to adjust the height position of the heat exchanger according to the height of the cabinet. The operator can complete the positioning and installation of the heat exchanger without lifting heavy objects. Thus, one person can complete the entire process of hoisting, positioning, and installation, reducing the difficulty of installing the heat exchanger for the operator, improving the flexibility and safety of the operation, reducing the risks that may be brought by manual handling for the operator, and enhancing the work efficiency and installation quality.

[0007] In some feasible embodiments of the present invention, the fixing component further includes: a bottom plate fixedly connected to the platform; a locking unit disposed between the bottom plate and the mounting plate. The locking unit is formed with a first locking portion and a second locking portion. The first locking portion is disposed on the bottom plate, and the second locking portion is disposed on the mounting plate. The mounting plate and the bottom plate are locked by the cooperation of the first locking portion and the second locking portion. When the fixing component is in the unlocked state, the first locking portion and the second locking portion are separated. When the fixing component is in the locked state, the first locking portion and the second locking portion are in contact.

[0008] In the above technical solution, the cooperation of the first locking portion and the second locking portion realizes the switching of the fixing component between the locked state and the unlocked state, thereby achieving the stable bearing of the heat exchanger and the flexible release of the mounting plate. In this way, when in the locked state, accidents and losses caused by the heat exchanger falling during the moving process can be avoided.

[0009] In some feasible embodiments of the present invention, the locking unit includes: a lock block and a lock hook. The lock block is disposed on the bottom plate, and the lock hook is disposed on the mounting plate. The lock block forms the first locking portion, and the lock hook forms the second locking portion. The lock block is located inside the lock hook, and the mounting plate and the bottom plate are locked by the cooperation of the lock block and the lock hook.

[0010] In the above technical solution, by providing a lock block and a lock hook, with the lock block disposed on the bottom plate and the lock hook disposed on the mounting plate, when the fixing component is in the locked state, the lock hook is buckled outside the lock block, realizing the locking between the mounting plate and the bottom plate. When the fixing component is unlocked, the lock block disengages from the lock hook, enabling the mounting plate to slide relative to the bottom plate. The lock hook and the lock block are fixed by mechanical structure engagement and are not easily loosened after locking. The fixing component is stable, reliable, and highly safe in the locked state.

[0011] In some feasible embodiments of the present invention, the fixing component further includes: a positioning unit, which is disposed between the bottom plate and the mounting plate. The positioning unit is formed with a first positioning portion and a second positioning portion. The first positioning portion is disposed on the bottom plate, and the second positioning portion is disposed on the mounting plate. The mounting plate and the bottom plate are positioned by the cooperation of the first positioning portion and the second positioning portion. When the fixing component is in the unlocked state, the first positioning portion is separated from the second positioning portion. When the fixing component is in the locked state, the first positioning portion is in contact with the second positioning portion to position the relative positions of the bottom plate and the mounting plate.

[0012] In the above technical solution, the relative positions between the mounting plate and the bottom plate are firmly locked through the cooperation of the first positioning portion and the second positioning portion, thereby achieving more stable support for the heat exchanger and precise positioning between the bottom plate and the mounting plate. In this way, the positioning unit and the locking unit cooperate with each other. In the locked state, it can effectively prevent the heat exchanger from falling during movement, causing accidents and losses.

[0013] In some feasible embodiments of the present invention, the positioning unit includes: a positioning block and a positioning pin. The positioning block is disposed on the bottom plate, and the positioning block is formed with a positioning hole, which forms the first positioning portion. The positioning pin is disposed on the mounting plate, and a through hole is formed on the mounting plate. The positioning pin is movably disposed in the through hole, and the positioning pin is formed with a positioning cylinder, which forms the second positioning portion. The positioning cylinder passes through the through hole and extends into the positioning hole. The mounting plate and the bottom plate are positioned by the cooperation of the positioning pin and the positioning block.

[0014] In the above technical solution, by providing a positioning block and a positioning pin, the first positioning portion is formed as a positioning hole, and the second positioning portion is formed as a positioning cylinder. The positioning cylinder extends into the positioning hole, realizing the positioning between the mounting plate and the bottom plate. When the fixing component is in the locked state, the positioning cylinder is located in the positioning hole, limiting the displacement of the mounting plate and the bottom plate in multiple directions, forming a rigid limit. When the fixing component is unlocked, the positioning cylinder disengages from the positioning hole, and at the same time, the lock block disengages from the lock hook, enabling the mounting plate to slide relative to the bottom plate. That is, through the cooperation between the positioning block and the positioning pin and the cooperation between the lock block and the lock hook, the displacement of the bottom plate and the mounting portion in multiple directions is restricted, effectively improving the stability and reliability of the fixing component in the locked state.

[0015] In some feasible embodiments of the present invention, the fixing component further includes: a sliding unit, which is disposed between the mounting plate and the bottom plate. The sliding unit is formed with a first sliding portion and a second sliding portion. The first sliding portion is disposed on the bottom plate, and the second sliding portion is disposed on the mounting plate. The mounting plate and the bottom plate are relatively slidably connected through the cooperation of the first positioning portion and the second positioning portion.

[0016] In the above technical solution, the smooth relative movement between the mounting plate and the bottom plate is realized through the cooperation of the first sliding portion and the second sliding portion. The first sliding portion and the second sliding portion reduce the friction between the mounting plate and the bottom plate. At the same time, the cooperation of the first sliding portion and the second sliding portion guides the relative movement of the mounting plate and the bottom plate, ensuring the balance and stability of the heat exchanger during the movement.

[0017] In some feasible embodiments of the present invention, the sliding unit includes: a guide rail and a slider. The guide rail is disposed on the bottom plate, and the first sliding portion is formed as the guide rail. The slider is disposed on the mounting plate, and the second sliding portion is formed as the slider. The slider is relatively slidably connected to the guide rail, and the mounting plate is relatively slidably connected to the bottom plate through the cooperation of the guide rail and the slider.

[0018] In some feasible embodiments of the present invention, the fixing component further includes: a guiding unit, which is disposed between the mounting plate and the bottom plate. The guiding unit is formed with a first guiding portion and a second guiding portion. The first guiding portion is disposed on the bottom plate, and the second guiding portion is disposed on the mounting plate. The mounting plate and the bottom plate are guided through the cooperation of the first guiding portion and the second guiding portion.

[0019] In the above technical solution, the moving direction of the mounting plate is guided through the cooperation of the first guiding portion and the second guiding portion, avoiding the occurrence of deviation or jamming, and improving the stability and safety during the movement of the mounting plate relative to the bottom plate. The guiding unit cooperates with the sliding unit to reduce the friction between the mounting plate and the bottom plate during the relative movement of the mounting plate and the bottom plate, and prevent lateral deviation or inclination during the relative movement of the mounting plate and the bottom plate, further ensuring the balance and stability of the heat exchanger during the movement.

[0020] In some feasible embodiments of the present invention, the guiding unit includes: a guiding shaft, a guiding block, and a buffer member. The guiding block is formed with a guiding hole, and the guiding shaft passes through the guiding hole. The guiding block is movable along the axial direction of the guiding shaft. The guiding shaft is formed as the first guiding portion, and the guiding hole is formed as the second guiding portion. The mounting plate and the bottom plate are guided through the cooperation of the guiding shaft and the guiding block, and the buffer member is sleeved at both ends of the guiding shaft.

[0021] In some feasible embodiments of the present invention, the mounting plate includes: a base plate, a fixing plate, and a supporting plate. The fixing plate is arranged perpendicular to the base plate, the fixing plate is connected to the base plate, the supporting plate is connected between the base plate and the fixing plate, and a plurality of mounting holes are formed in the fixing plate. At least part of the plurality of mounting holes are formed as elongated holes.

Moreover, a plurality of mounting holes are formed in the fixing plate, and the mounting holes are formed as elongated holes, providing a lateral or longitudinal adjustment space for the heat exchanger, facilitating the adaptation of the installation positions of different models of heat exchangers.

[0023] In some feasible embodiments of the present invention, the installation device of the heat exchanger further includes: a lifting mechanism and a base. The lifting mechanism is arranged between the base and the platform. The lifting mechanism includes: a transmission assembly and a driving assembly. The driving assembly is connected to the platform through the transmission assembly and is used to drive the platform to move in the up and down directions.

[0024] In the above technical solution, the movement of the platform in the up and down directions is realized by providing the lifting mechanism. The lifting mechanism includes a transmission assembly and a driving assembly. The transmission assembly is connected between the platform and the base. The upper end of the transmission assembly is connected to the platform, and the lower end of the transmission assembly is connected to the base. The driving assembly is in transmission connection with the transmission assembly, and the driving assembly can drive the transmission assembly to drive the platform to move upward or downward.

[0025] In some feasible embodiments of the present invention, 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 to each other. One end of the first linkage rod is respectively connected to one end of the second linkage rod of an adjacent linkage group, and one end of the second linkage rod is respectively connected to one end of the first linkage rod of an adjacent linkage group.

[0026] In the above technical solution, the plurality of linkage groups form a scissor structure with a plurality of hinge points for evenly distributing the load, so that the pressure borne by a single hinge point is small, enhancing the overall load-bearing capacity, providing multi-point support, and increasing the stability of the platform. When not in use, the scissor structure can be completely folded, occupying extremely small space, facilitating placement and transportation.

[0029] In the above technical solution, by setting the starting capacitor, the starting characteristics of the driving pump are improved, so that the driving pump can obtain sufficient torque at a lower starting current to overcome the resistance in the static state, with low failure rate, easy to maintain, low production cost, and strong adaptability.

[0030] According to the hydraulic system of the second aspect of the present invention, it is applied to the installation device of the heat exchanger according to the first aspect of the present invention.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above accompanying drawing descriptions are intended to cover non-exclusive inclusion.

[0039] In the description of the embodiments of the present invention, technical terms such as "first" and "second" are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity, specific order, or primary-secondary relationship of the indicated technical features. In the description of the embodiments of the present invention, the meaning of "a plurality" is more than two, unless otherwise specifically defined.

[0040] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The phrase appears in various places in the specification and is not necessarily referring to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this text generally represents an "or" relationship between the associated objects before and after.

[0042] In the description of the embodiments of the present invention, the term "a plurality" refers to more than two (including two).

[0043] In the related art, it is pointed out that the secondary-side CDU (Cooling Distribution Unit) of the liquid-cooled server cooling system is a key component. The plate heat exchanger cooperates with the CDU in the secondary-side circulation, transfers the heat of the server to the coolant through the cold plate, and finally completes the heat exchange by the plate heat exchanger. The weight of the plate heat exchanger is more than 75 kilograms, and the heaviest currently reaches 150 kilograms. Moreover, there is no auxiliary handling structure such as a lifting handle on the surface, making it difficult to install manually on the CDU. The existing gantry cranes on the market have large structural dimensions, large floor areas, and are inconvenient for people to operate below. The lifting wire cannot be rigidly positioned. The mobile gantry crane has poor stability and limited load-carrying capacity. The ground track of the gantry crane is prone to hidden dangers and requires regular maintenance and anti-corrosion treatment, otherwise it will affect the service life. The pneumatic balance crane has poor stability when the load changes due to the compressibility of air, and the exhaust noise is large. Although it can be used for human-machine cooperation, its operation flexibility is not high, the working pressure is low, the structural dimensions are limited, the output power is small, and the positioning accuracy is not as good as that of the intelligent crane. The suspension height is limited, and the compatibility with the plate heat exchanger for cabinets and CDUs of different heights is poor. Therefore, how to handle and install the plate heat exchanger more flexibly and efficiently has become an urgent problem to be solved.

[0044] Based on the above considerations, in order to handle and install the plate heat exchanger more flexibly and efficiently, the inventor has conducted in-depth research and designed an installation device for the heat exchanger. The following refers to Figures 1-6Describe the installation device of the heat exchanger according to the embodiments of the first aspect of the present invention.

[0045] As Figures 1-6 shown, Figure 1 is a schematic diagram of the use of an installation device for a heat exchanger provided by an embodiment of the present invention; Figure 2 is a schematic diagram of the installation device of the heat exchanger according to the embodiment of the present invention; Figure 3 is Figure 2 a schematic diagram of the fixing component shown in Figure 4 is Figure 3 a 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 is a schematic diagram of an electrical control principle according to an embodiment of the present invention.

[0046] The installation device 100 of the heat exchanger according to the embodiments of the first aspect of the present invention includes: a platform 1 and a fixing component 2.

[0047] Specifically, the platform 1 is movable in the up and down direction. The fixing component 2 is arranged on the platform 1. The fixing component 2 includes a mounting plate 21. The heat exchanger 300 is adapted to be arranged on the mounting plate 21. 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 towards the outside of the platform 1 so that the heat exchanger 300 is located outside the platform 1. Thus, the platform 1 can be adjusted in the up and down direction, 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 does not fall stably during transportation. When the fixing component 2 is switched to the unlocked state, the mounting plate 21 can move towards 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 cabinet height, and the operator can complete the positioning and installation of the heat exchanger 300 without lifting heavy objects, improving the flexibility and safety of the operation, reducing the risk that the operator may bring due to manual handling, and improving the work efficiency and installation quality.

[0048] It can be understood that, as Figure 1 and Figure 2As shown in the figure, the platform 1 is a basic bearing structure for installing the device 100 to carry the heat exchanger 300. The platform 1 has an ascending motion and a descending motion, that is, the platform 1 can be adjusted vertically up and down, facilitating the operator to adjust the height position of the heat exchanger 300 according to the height of the cabinet. The fixing component 2 is fixedly arranged on the platform 1 and is used to fix the heat exchanger 300. The fixing component 2 includes a mounting plate 21, and 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 the locked state, the mounting plate 21 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 device 100 moves, it avoids the damage of the heat exchanger 300 caused by falling from the platform 1 to the ground. When the fixing component 2 is switched from the locked state to the unlocked state, the mounting plate 21 can move to the outside of the platform 1. At this time, the heat exchanger 300 moves towards the outside of the platform 1 following the mounting plate 21. 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, facilitating the operator to assemble the heat exchanger 300 with the cabinet.

[0049] For the heat exchanger installation device 100 according to the embodiment of the present invention, by setting the 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, reducing the difficulty of the operator in installing the heat exchanger 300, improving the flexibility and safety of the operation, reducing the risks that may be brought by manual handling by the operator, and improving the work efficiency and installation quality.

[0050] In any embodiment of the present invention, the fixing component 2 further includes: a bottom plate 22 and a locking unit 23. The bottom plate 22 is fixedly connected to the platform 1, and the locking unit 23 is arranged between the bottom plate 22 and the mounting plate 21. The locking unit 23 is formed with a first locking portion and a second locking portion. The first locking portion is arranged on the bottom plate 22, and the second locking portion is arranged on the mounting plate 21. The mounting plate 21 and the bottom plate 22 are locked by the cooperation of the first locking portion and the second locking portion. When the fixing component 2 is in the unlocked state, the first locking portion and the second locking portion are separated. When the fixing component 2 is in the locked state, the first locking portion and the second locking portion are in contact. Thus, through the cooperation of the first locking portion and the second locking portion, the fixing component 2 is switched between the locked state and the unlocked state, thereby realizing the stable bearing of the heat exchanger 300 and the flexible release of the mounting plate 21. In this way, in the locked state, it can avoid accidents and losses caused by the heat exchanger 300 falling during the movement process.

[0051] It is understandable that a first locking portion is provided on the bottom 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 can be switched between a locked state and an unlocked state. When the mounting plate 21 and the bottom plate 22 move relative to each other, the first locking portion and the second locking portion change from being in contact with each other to being separated from each other, and thus the fixing assembly 2 is switched from the locked state to the unlocked state. Or, when the mounting plate 21 and the bottom plate 22 move relative to each other, the first locking portion and the second locking portion change from being separated from each other to being in contact with each other, and thus the fixing assembly 2 is switched from the unlocked state to the locked state. The locking unit 23 is modularly designed, which is convenient for replacement and maintenance. The locking unit 23 ensures the safety of the heat exchanger 300 during the movement process and avoids damage to the heat exchanger 300.

[0052] Further, the locking unit 23 includes a locking block 231 and a locking hook 232. The locking block 231 is provided on the bottom plate 22, and the locking hook 232 is provided on the mounting plate 21. The locking block 231 forms the first locking portion, and the locking hook 232 forms the second locking portion. The locking block 231 is located within the locking hook 232, and the mounting plate 21 and the bottom plate 22 are locked by the cooperation of the locking block 231 and the locking hook 232. Thus, by providing the locking block 231 and the locking hook 232, with the locking block 231 provided on the bottom plate 22 and the locking hook 232 provided on the mounting plate 21, when the fixing assembly 2 is in the locked state, the locking hook 232 is buckled outside the locking block 231, realizing the locking between the mounting plate 21 and the bottom plate 22. When the fixing assembly 2 is unlocked, the locking block 231 disengages from the locking hook 232, enabling the mounting plate 21 to slide relative to the bottom plate 22. The locking hook 232 and the locking block 231 are fixed by mechanical structure occlusion and are not easily loosened after locking. The fixing assembly 2 is stable, reliable and highly safe in the locked state.

[0053] Referring to Figure 3 As shown, it is understandable that the locking block 231 is fixedly provided on the bottom 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 is separated from the locking block 231, enabling the mounting plate 21 to slide or move outward relative to the bottom plate 22. The structure of the locking unit 23 is simple, with 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 wrapped by the locking hook 232 to form a firm connection. At this time, the mounting plate 21 is completely located above the bottom plate 22 and cannot move horizontally, effectively preventing the heat exchanger 300 from shifting or falling.

[0054] Furthermore, a first guiding surface is formed on the locking block 231, and a second guiding surface is formed on the locking hook 232. The first guiding surface cooperates with the second guiding surface for guiding. The locking hook 232 is provided with an elastic member, and the elastic member has a force that connects the locking hook 232 to the locking block 231. It can be understood that the locking block 231 and the locking hook 232 cooperate through the first guiding surface and the second guiding surface to achieve the guiding and locking between the locking hook 232 and the locking block 231. The first guiding surface is formed on the locking block 231, and the second guiding surface is formed on the locking hook 232. During the sliding of the mounting plate 21, the first guiding surface of the locking block 231 contacts the second guiding surface on the locking hook 232, guiding the locking block 231 to be wrapped by the locking hook 232 to complete the locking action. In this way, the operator can complete the locking without precise alignment, with low operation difficulty and improved assembly efficiency of the operator; the elastic member provides a force that keeps the locking hook 232 and the locking block 231 in contact all the time, which can prevent accidental unlocking caused by vibration or small displacement, reduce the risk of accidental unlocking caused by external interference, and enhance the locking stability of the fixing component 2.

[0055] In some feasible embodiments, a proximity switch or a pressure sensor may also be provided on the locking hook 232 or the locking block 231 to be used for detecting in real time whether the locking hook 232 and the locking block 231 are locked in place, improving the reliability of the locking unit 23.

[0056] In any embodiment of the present invention, the fixing component 2 further includes: a positioning unit 24. The positioning unit 24 is disposed between the bottom plate 22 and the mounting plate 21. The positioning unit 24 is formed with a first positioning portion and a second positioning portion. The first positioning portion is disposed on the bottom plate 22, and the second positioning portion is disposed on the mounting plate 21. The mounting plate 21 and the bottom plate 22 are positioned by the cooperation of the first positioning portion and the second positioning portion. When the fixing component 2 is in the unlocked state, the first positioning portion and the second positioning portion are separated. When the fixing component 2 is in the locked state, the first positioning portion and the second positioning portion are in contact to position the relative positions of the bottom plate 22 and the mounting plate 21. Thus, the relative positions between the mounting plate 21 and the bottom plate 22 are firmly locked through the cooperation of the first positioning portion and the second positioning portion, thereby achieving more stable loading of the heat exchanger 300 and precise positioning between the bottom plate 22 and the mounting plate 21. In this way, the positioning unit 24 and the locking unit 23 cooperate with each other. In the locked state, it can effectively avoid accidents and losses caused by the heat exchanger 300 falling during the moving process.

[0057] 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 have relative displacement, the relative position between the mounting plate 21 and the bottom plate 22 is more stable. When the mounting plate 21 and the bottom plate 22 move relative to each other, the first positioning portion and the second positioning portion are separated from being in contact with each other, and at the same time, the first locking portion and the second locking portion are separated from being in contact with each other. In this way, the fixing assembly 2 is switched from the locked state to the unlocked state. Or, when the mounting plate 21 and the bottom plate 22 move relative to each other, the first positioning portion and the second positioning portion change from being separated to being in contact with each other, and the first locking portion and the second locking portion change from being separated to being in contact with each other. In this way, the fixing assembly 2 is switched from the unlocked state to the locked state. The fixing unit and the locking unit 23 cooperate with each other. After the locking block 231 is located within the locking hook 232, the first positioning portion and the second positioning portion come into contact, improving the precise positioning between the mounting plate 21 and the bottom plate 22, restricting the displacement between the bottom plate 22 and the mounting portion in multiple directions, reducing the wear of the locking unit 23, and preventing damage to the locking hook 232 or the locking block 231 caused by misalignment.

[0058] Further, the positioning unit 24 includes: a positioning block 241 and a positioning pin 242. The positioning block 241 is provided on the bottom plate 22. The positioning block 241 is formed with a positioning hole, and the positioning hole forms the first positioning portion. The positioning pin 242 is provided on the mounting plate 21. A through hole is formed on the mounting plate 21. The positioning pin 242 is movably disposed within the through hole. The positioning pin 242 is formed with a positioning cylinder, and the positioning cylinder forms the second positioning portion. The positioning cylinder passes through the through hole and extends into the positioning hole. The mounting plate 21 and the bottom plate 22 are positioned by the cooperation of the positioning pin 242 and the positioning block 241. Thus, by providing the positioning block 241 and the positioning pin 242, the first positioning portion is formed as the positioning hole, the second positioning portion is formed as the positioning cylinder, and the positioning cylinder extends into the positioning hole, realizing the positioning between the mounting plate 21 and the bottom plate 22. When the fixing assembly 2 is in the locked state, the positioning cylinder is located within the positioning hole, restricting the displacement of the mounting plate 21 and the bottom plate 22 in multiple directions and forming a rigid limit. When the fixing assembly 2 is unlocked, the positioning cylinder disengages from the positioning hole, and at the same time, the locking block 231 disengages from the locking hook 232, enabling the mounting plate 21 to slide relative to the bottom 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 bottom plate 22 and the mounting portion in multiple directions is restricted, effectively improving the stability and reliability of the fixing assembly 2 in the locked state.

[0059] Refer to Figure 3As shown, the positioning block 241 is provided on the bottom plate 22, the positioning hole is formed on the positioning block 241, the positioning pin 242 is provided on the mounting plate 21, a through hole is formed on the mounting plate 21, the positioning pin 242 is movably provided in the through hole, the positioning pin 242 is formed with a positioning cylinder, the first positioning portion is formed as the positioning hole, the second positioning portion is formed as the positioning cylinder. When the fixing component 2 is in the locked state, the locking hook 232 is buckled outside the locking block 231, the positioning cylinder passes through the through hole and extends into the positioning hole, and no relative displacement can occur between the mounting plate 21 and the bottom plate 22. When the fixing component 2 is unlocked, the locking block 231 disengages from the locking hook 232, and the positioning cylinder disengages from the positioning hole, so that the mounting plate 21 can slide relative to the bottom plate 22.

[0060] In any embodiment of the present invention, the fixing component 2 further includes: a sliding unit 25, the sliding unit 25 is provided between the mounting plate 21 and the bottom plate 22, the sliding unit 25 is formed with a first sliding portion and a second sliding portion, the first sliding portion is provided on the bottom plate 22, the second sliding portion is provided on the mounting plate 21, and the mounting plate 21 and the bottom plate 22 are relatively slidably connected through the cooperation of the first positioning portion and the second positioning portion. Thus, the smooth and stable relative movement between the mounting plate 21 and the bottom plate 22 is realized through the cooperation of the first sliding portion and the second sliding portion. The first sliding portion and the second sliding portion reduce the friction between the mounting plate 21 and the bottom plate 22. At the same time, the cooperation of the first sliding portion and the second sliding portion guides the relative movement of the mounting plate 21 and the bottom plate 22, ensuring the balance and stability of the heat exchanger 300 during the movement.

[0061] Furthermore, referring to Figure 3 As shown, the sliding unit 25 includes: a guide rail 251 and a slider 252. The guide rail 251 is provided on the bottom plate 22, the first sliding portion is formed as the guide rail 251, the slider 252 is provided on the mounting plate 21, the second sliding portion is formed as the slider 252, the slider 252 is relatively slidable with the guide rail 251, and the mounting plate 21 is relatively slidably connected with the bottom plate 22 through the cooperation of 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, the mounting plate 21 and the bottom plate 22 slide relatively, and the slider 252 slides along the length direction of the guide rail 251, which not only provides a guiding function for the sliding of the mounting plate 21, but also reduces the friction generated when the mounting plate 21 and the bottom plate 22 slide relatively.

[0062] Even further, 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 around the circumference of the guide rail 251, which avoids the separation between the slider 252 and the guide rail 251, ensures the stable operation of the sliding unit 25, and further improves the stability and reliability of the fixing component 2.

[0063] In any embodiment of the present invention, the fixing component 2 further includes: a guiding unit 26, the guiding unit 26 is disposed between the mounting plate 21 and the bottom plate 22, the guiding unit 26 is formed with a first guiding portion and a second guiding portion, the first guiding portion is disposed on the bottom plate 22, the second guiding portion is disposed on the mounting plate 21, and the mounting plate 21 and the bottom plate 22 are guided by the cooperation of the first guiding portion and the second guiding portion. Thus, by the cooperation of the first guiding portion and the second guiding portion to guide the moving direction of the mounting plate 21, the situation of deviation or jamming is avoided, and the stability and safety during the movement of the mounting plate 21 relative to the bottom plate 22 are improved. The guiding unit 26 cooperates with the sliding unit 25. During the relative movement of the mounting plate 21 and the bottom plate 22, while reducing the friction between the mounting plate 21 and the bottom plate 22, it prevents lateral deviation or inclination during the relative movement of the mounting plate 21 and the bottom plate 22, and further ensures the balance and stability of the heat exchanger 300 during the movement.

[0064] Referring to Figure 3 As shown, in a feasible embodiment, the guiding unit 26 includes: a guiding shaft 261, a guiding block 262 and a buffer member 263.

The buffer member 263 is sleeved at both ends of the guiding shaft 261. When the fixing component 2 switches from the unlocked state to the locked state, the mounting plate 21 moves towards the inner side of the platform 1, and there is relative sliding between the mounting plate 21 and the bottom plate 22. While the slider 252 slides along the length direction of the guide rail 251, the guiding block 262 slides along the axial direction of the guiding shaft 261 to guide the mounting plate 21 during the sliding of the mounting plate 21. The cooperation of the guide rail 251 and the slider 252 and the cooperation of the guiding shaft 261 and the guiding block 262 guide the mounting plate 21 while sliding relative to the bottom plate 22, and buffer members 263 are provided at both ends of the guiding shaft 261 to absorb impact energy when the mounting plate 21 slides to the extreme positions at both ends of the guiding shaft 261, prevent hard collisions, avoid the situation of structural damage, and extend the service life of the installation device 100.

[0065] In any embodiment of the present invention, as 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 is arranged perpendicular to the base plate 211 and connected to the base plate 211. The support plate 213 is connected between the base plate 211 and the fixing plate 212. Multiple mounting holes 214 are formed on the fixing plate 212, and at least part of the multiple mounting holes 214 are formed as elongated holes. Thus, by providing the support plate 213, the overall structural rigidity of the mounting plate 21 is enhanced, the bending resistance and stability of the mounting plate 21 when bearing heavy loads are improved, and multiple mounting holes 214 are formed on the fixing plate 212. The mounting holes 214 are formed as elongated holes, providing lateral or longitudinal adjustment space for the heat exchanger 300, facilitating the adaptation to the installation positions of different models of the heat exchanger 300.

A wear-resistant member 5 is provided below the mounting plate 21, and the wear-resistant member 5 is connected to the bottom plate 22. The wear-resistant member 5 protects the appearance of the heat exchanger 300 product and avoids damage to the appearance of the heat exchanger 300.

It can be understood that the base 4 is the basic support structure of the entire device.

One end of the first linkage rod is respectively connected to one end of the second linkage rod of an adjacent linkage group, and one end of the second linkage rod is respectively connected to one end of the first linkage rod of an adjacent linkage group. Referring to Figure 1 and Figure 2As shown, multiple linkage groups are formed into a scissor structure, which has multiple hinge points for evenly distributing the load, so that the pressure on a single hinge point is small, enhancing the overall load-bearing capacity, providing multi-point support, and increasing the stability of the platform 1. When not in use, the scissor structure can be completely folded, occupying extremely small space, facilitating placement and transportation.

[0075] In some other embodiments, the platform 1 can also be raised to approximately the height of the connection pipe interface of the liquid-cooled server cabinet, the locking hook 232 and the positioning pin 242 are loosened, and the mounting plate 21 and the heat exchanger 300 are pushed out.

[0076] The hydraulic system 200 according to the embodiment of the second aspect of the present invention is applied to the installation device 100 of the heat exchanger according to the embodiment of the first aspect of the present invention. The hydraulic system 200 includes: a main passage 201, a return 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 assembly of the installation device 100. A drive pump 205 and a check valve 206 are connected in series on the main passage 201. A filter 209 is provided downstream of the oil tank 204. The return passage 202 has a return oil inlet end and a return oil outlet end. The return oil inlet end is connected between the main oil outlet end and the check valve 206, and the return 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 check valve 206, and the overflow oil outlet end is connected to the main oil inlet end.

[0077] When the hydraulic system 200 is working, first, hydraulic oil is sucked 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 check valve 206 and flows to the drive assembly (such as a hydraulic cylinder) to push the platform 1 to rise or perform an action. After the drive assembly completes the action, the hydraulic oil returns to the main passage 201 through the return passage 202. A throttle valve can be set in the return path to adjust the speed, or a directional valve can be used to change the movement direction. 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.

[0078] The hydraulic system 200 according to the embodiment of the present invention ensures the stable operation of the system through multiple protections of the overflow valve 208, the check valve 206, and the filter 209. Each passage has a clear division of labor, which is convenient for system design and maintenance. The return passage 202 reduces energy consumption loss and improves the overall efficiency.

[0079] Next, reference will be made to Figures 1-6 Describe the installation device 100 of the heat exchanger according to a specific embodiment of the present invention.

[0080] As Figures 1-4As shown, the installation device 100 of the radiator includes: a platform 1, a fixing component 2, a lifting mechanism 3, a base 4, and a lifting electrical control system. The fixing component 2 includes: a mounting plate 21, a bottom plate 22, a locking unit 23, a positioning unit 24, a sliding unit 25, a guiding unit 26, a pushing handle 6, a directional wheel 7, a universal wheel 8, a rising switch, a descending switch, and a hydraulic system 200.

[0081] Specifically, the platform 1 is the basic load-bearing structure of the installation device 100 for carrying the heat exchanger 300. The platform 1 has upward and downward movements, that is, the platform 1 can be adjusted in the vertical direction, facilitating the operator to adjust the height position of the heat exchanger 300 according to the height of the cabinet. The fixing component 2 is fixedly arranged on the platform 1 and is used to fix the heat exchanger 300. The fixing component 2 includes a mounting plate 21, and 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 the locked state, the mounting plate 21 is completely above the platform 1. At this time, the heat exchanger 300 is also completely above the platform 1. In this way, when the installation device 100 moves, it avoids the damage of the heat exchanger 300 caused by falling from the platform 1 to the ground. When the fixing component 2 is switched from the locked state to the unlocked state, the mounting plate 21 can move outward 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.
