Description

Technical Field

[0001] This application relates to the field of server cooling technology, and more specifically, to a cooling device and an immersion cooling device. Background Technology

[0002] Liquid cooling technology is widely used in the server field due to its high heat dissipation capability. Among them, immersion liquid cooling immerses the entire server body in a specific refrigerant and uses the flow and phase change of the refrigerant to achieve rapid heat dissipation, which significantly improves heat dissipation efficiency and reduces energy consumption.

[0003] However, during operation, servers require real-time status feedback via indicator lights (such as hard drive status lights, fault lights, and network status lights) on their chassis. The immersion liquid cooling environment significantly reduces the visibility of these indicator lights. Currently, cooling devices typically use transparent viewing windows, but the refraction effect of the refrigerant causes the light path to deviate, making it impossible for maintenance personnel to accurately identify the indicator light status through the viewing window. Furthermore, frequent opening of the cover for inspection can not only cause refrigerant contamination or vaporization loss but also lead to decreased equipment heat dissipation stability and even safety hazards due to refrigerant leaks. This problem is particularly prominent in data center inspections, health checks, and fault location scenarios, directly impacting maintenance efficiency and equipment reliability.

[0004] Therefore, how to achieve visual monitoring of the server's indicator lights while ensuring efficient heat dissipation through immersion liquid cooling has become a pressing technical challenge. Summary of the Invention

[0005] In view of this, this application provides a cooling device that, by setting a movable lens inside the enclosure containing the server body and the refrigerant, displaces the refrigerant at the top of the server body, allowing the indicator surface to be better observed through the lens, thereby reducing the negative impact on the visibility of the indicator surface in an immersion liquid cooling environment.

[0006] One aspect of this application provides a cooling device including a housing and a lens. The housing defines a receiving cavity in which a server body and a refrigerant immersing the server body are disposed, the server body having an upward-facing indicator surface; the lens, disposed in the receiving cavity, includes a first surface facing the server body and a second surface opposite to the first surface, the second surface being exposed above the liquid surface of the refrigerant; wherein the lens has a first state in which the first surface abuts against the indicator surface, and a second state in which the first surface is detached from the indicator surface.

[0007] According to an embodiment of this application, the aforementioned receiving cavity contains at least one of the aforementioned server bodies; the aforementioned cooling device further includes a first adjustment mechanism, the aforementioned lens is disposed on the aforementioned first adjustment mechanism and configured to move along the height direction with the aforementioned first adjustment mechanism, so that the aforementioned lens abuts against the aforementioned indicating surface along the height direction, or moves away from the aforementioned indicating surface.

[0008] According to an embodiment of this application, the aforementioned receiving cavity has at least two of the aforementioned server bodies, and the at least two of the aforementioned server bodies are arranged side by side within the aforementioned receiving cavity; the aforementioned cooling device further includes a second adjustment mechanism disposed on the aforementioned first adjustment mechanism, the aforementioned lens disposed on the aforementioned second adjustment mechanism, the aforementioned second adjustment mechanism being configured to move along the height direction with the aforementioned first adjustment mechanism, and the aforementioned lens being configured to move along the horizontal direction with the aforementioned second adjustment mechanism, so that the aforementioned lens is positioned above the aforementioned indicating surface of one of the aforementioned server bodies in the horizontal direction.

[0009] According to an embodiment of this application, the first adjustment mechanism includes: at least one guide rail and a first drive unit, wherein at least one guide rail is disposed in the receiving cavity and is configured to extend along the height direction, and the second adjustment mechanism is slidably disposed on the guide rail; the first drive unit is disposed in the receiving cavity and is configured to drive the second adjustment mechanism to move the lens along the guide rail, so as to change the relative position of the first surface of the lens with at least two of the server bodies along the height direction.

[0010] According to an embodiment of this application, the first driving unit includes at least one elastic part and at least one pressing part. The at least one elastic part is disposed between the guide rail and the second adjusting mechanism and is configured to apply an upward supporting force to the second adjusting mechanism; the at least one pressing part is connected to the second adjusting mechanism and is configured to apply a downward pressure to the second adjusting mechanism by an external force; wherein, by adjusting the pressure, the second adjusting mechanism drives the lens to move along the height direction.

[0011] According to an embodiment of this application, the second adjustment mechanism includes at least one second drive unit and a transmission part. The at least one second drive unit is slidably disposed on the guide rail; the transmission part is disposed on the second drive unit, the lens is mounted on the transmission part, and is configured to move horizontally along with the transmission part under the drive of the second drive unit, thereby changing the relative position of the lens with respect to at least two of the server bodies in the horizontal direction.

[0012] According to an embodiment of this application, the second adjustment mechanism is provided with two second drive units, which are symmetrically arranged at both ends of the transmission part along the horizontal direction. Each second drive unit includes: a winding roller rotatably disposed on the guide rail; and an operating handle fixed to one end of the winding roller, allowing the user to manually drive the winding roller to rotate. The transmission part includes a flexible transmission belt, with both ends of the flexible transmission belt wound around the circumference of the two winding rollers respectively. The lens is disposed in a straight area in the middle of the flexible transmission belt. When the two winding rollers rotate in the same direction, the lens is moved along the horizontal direction by winding and releasing the flexible transmission belt.

[0013] According to an embodiment of this application, the cooling device further includes a cover detachably disposed on the housing to close the receiving cavity when assembled with the housing; wherein the cover has a viewing window, allowing the user to observe the lens from outside the cover.

[0014] According to an embodiment of this application, the pressing part is configured to extend beyond the cover through a through hole, so that when the receiving cavity is closed, the user can use the pressing part to bring the lens against the indicator surface in the height direction and observe.

The server body has an indicator surface, which is provided with at least one of a hard disk status light, a hard disk fault light, a network port status light, a server body identification light, and a system fault light.

[0016] According to the embodiments of this application, the problem of indicator lights being invisible due to refrigerant refraction / scattering in immersion liquid cooling environments is solved by switching the contact or separation state of the first surface of the lens with the indicator surface of the server body. In the first state, the lens directly abuts the indicator surface, eliminating the interference of the refrigerant on the light path, allowing the light from the indicator light (such as an indicator light or fault light) to pass directly through the lens to the surface of the refrigerant, ensuring that maintenance personnel can clearly observe the light status through the second surface of the lens. In the second state, the lens separates from the indicator surface, avoiding structural interference or heat conduction effects that may be caused by long-term contact, while maintaining the flow space of the refrigerant and ensuring heat dissipation efficiency. This approach balances the high-efficiency heat dissipation requirements of immersion liquid cooling with the need for equipment status visualization, enabling distortion-free observation without opening the cover, reducing the risk of refrigerant contamination, and improving maintenance safety and convenience.

[0051] The embodiments of this application will now be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of this application. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the embodiments of this application for ease of explanation. However, it will be apparent that one or more embodiments may be implemented without these specific details. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concepts of this application.

[0052] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0053] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0054] When using expressions such as "at least one of A, B and C", they should generally be interpreted in accordance with the meaning that is commonly understood by those skilled in the art (e.g., "a system having at least one of A, B and C" should include, but is not limited to, a system having A alone, a system having B alone, a system having C alone, a system having A and B, a system having A and C, a system having B and C, and / or a system having A, B and C, etc.).

[0055] Figure 1 This schematically illustrates a structural view of a cooling device according to an embodiment of the present application, taken from the front view. Figure 2 The schematic diagram shows a top view of the cooling device according to an embodiment of this application; Figure 3 The diagram illustrates the path of light rays on the indicator surface of the server body when the lens is set according to an embodiment of this application.

[0056] Embodiments of this application provide a cooling device, such as... Figures 1 to 3 As shown, the device includes a housing 1 and a lens 3. The housing 1 defines a receiving cavity 11, in which a server body 2 and a refrigerant 7 immersed in the server body 2 are disposed. The server body 2 has an upwardly facing indicator surface 21. The lens 3 is disposed in the receiving cavity 11 and includes a first surface 31 facing the server body 2 and a second surface 32 opposite to the first surface 31. The second surface 32 is exposed above the liquid surface of the refrigerant 7. The lens 3 has a first state in which the first surface 31 abuts against the indicator surface 21 and a second state in which the first surface 31 is detached from the indicator surface 21.

[0057] Based on the above configuration, the switchable design of lens 3 between the first state (contacting the indicator surface 21) and the second state (detached from the indicator surface 21) effectively solves the observation problem of the server body 2 indicator lights caused by the refrigerant 7 refraction / scattering in the immersion liquid cooling environment. In the first state, lens 3 is in direct contact with the indicator surface 21, eliminating the interference of refrigerant 7 on the optical path, allowing the light from the indicator lights (such as blue and green short-wavelength light sources) to pass directly through lens 3 to the liquid surface, achieving distortion-free observation. In the second state, lens 3 is separated from the indicator surface 21, ensuring that the flow space of refrigerant 7 is unobstructed and maintaining heat dissipation efficiency. This design balances the dual requirements of efficient heat dissipation and status visualization, allowing for accurate identification of indicator light status without opening the cover, avoiding the risk of refrigerant 7 contamination and thermal runaway, and significantly improving operational safety and equipment maintainability.

[0058] In one illustrative embodiment, such as Figure 1 and Figure 2 As shown, the cavity 11 contains at least one server body 2; the cooling device also includes a first adjustment mechanism 5, a lens 3 disposed on the first adjustment mechanism 5 and configured to move along the height direction with the first adjustment mechanism 5 so that the lens 3 abuts against the indicator surface 21 or moves away from the indicator surface 21 along the height direction.

[0059] According to the above configuration, when the lens 3 is pressed down to the first state by the first adjustment mechanism 5, its first surface 31 is in direct contact with the indicator surface 21 of the server body 2, eliminating the refraction and scattering effect of the refrigerant 7 on the indicator light, ensuring high-fidelity transmission of short-wavelength signals, and enabling maintenance personnel to clearly identify the indicator light status through the second surface 32 of the lens 3 above the liquid surface; when the lens 3 rises to the second state, it separates from the indicator surface 21, and the refrigerant 7 refills the gap, avoiding the increase in local thermal resistance caused by contact, and maintaining the overall heat dissipation performance of the liquid cooling system.

[0060] In one illustrative embodiment, such as Figure 1 and Figure 2 As shown, the receiving cavity 11 has at least two server bodies 2, and the at least two server bodies 2 are arranged side by side in the receiving cavity 11; the cooling device also includes a second adjustment mechanism 6, which is disposed between the first adjustment mechanism 5 and the lens 3. The lens 3 is disposed on the second adjustment mechanism 6. The second adjustment mechanism 6 is configured to move with the first adjustment mechanism 5 in the height direction, and the lens 3 is configured to move with the second adjustment mechanism 6 in the horizontal direction, so that the lens 3 is positioned above the indicator surface 21 of one of the server bodies 2 in the horizontal direction.

[0061] In detail, the lens 3 is also configured to move horizontally along with the second adjustment mechanism 6 in the second state.

[0062] Based on the above setup, the precise positioning and dynamic adaptation of the lens 3 in a scenario where multiple server bodies 2 are arranged side by side are achieved through the coordinated action of the second adjustment mechanism 6 and the first adjustment mechanism 5.

[0063] In detail, the second adjustment mechanism 6 drives the lens 3 to move horizontally, so that it covers the indicator surface 21 of any target server body 2. Combined with the vertical lifting function of the first adjustment mechanism 5, the lens 3 can quickly switch to contact or detach from the indicator surface 21 of the target server body 2. This solves the observation problem caused by the dispersed position of indicator lights in a cluster of multiple server bodies 2. Users can complete the status inspection of all server bodies 2 through a single lens 3 without opening the cover or moving the server bodies 2, significantly improving the operation and maintenance efficiency of high-density data centers.

[0064] Figure 4 An enlarged view of the structure at the guide rail according to an embodiment of this application is shown schematically.

[0065] In one illustrative embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, the first adjustment mechanism 5 includes at least one guide rail 51 and a first drive unit 52; the guide rail 51 is disposed in the receiving cavity 11 and is configured to extend along the height direction, and the second adjustment mechanism 6 is slidably disposed on the guide rail 51; the first drive unit 52 is disposed in the receiving cavity 11 and is configured to drive the second adjustment mechanism 6 to move the lens 3 along the guide rail 51 to change the relative position of the lens 3 on at least two server bodies 2 along the height direction.

[0066] According to the above configuration, the first adjustment mechanism 5, through the cooperation of the guide rail 51 and the first drive unit 52, achieves precise and stable adjustment of the lens 3 in the height direction.

[0067] According to an embodiment of this application, the guide rail 51 extends rigidly along the height direction to provide a low-friction sliding guide for the second adjustment mechanism 6; the first drive unit 52 drives the second adjustment mechanism 6 to rise and fall as a whole, so that the first surface 31 of the lens 3 can be quickly adjusted to adjust the relative height with the indicator surface 21 of the server body 2 as needed, which facilitates the adjustment of the horizontal position.

[0068] Furthermore, the height adjustment of the first adjustment mechanism 5 and the horizontal adjustment of the second adjustment mechanism 6 form an orthogonal synergy, jointly realizing the omnidirectional positioning of the lens 3 in three-dimensional space, significantly reducing the complexity of operation and maintenance and improving the response speed and reliability of equipment inspection.

[0069] In one illustrative embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the first driving unit 52 includes at least one elastic part 521 and at least one pressing part 522; the elastic part 521 is disposed between the guide rail 51 and the second adjustment mechanism 6 and is configured to apply an upward supporting force to the second adjustment mechanism 6; the pressing part 522 is connected to the second adjustment mechanism 6 and is configured to apply a downward pressure to the second adjustment mechanism 6 by an external force; wherein, by adjusting the pressure, the second adjustment mechanism 6 drives the lens 3 to move along the height direction.

[0070] According to the above configuration, the first drive unit 52 achieves stepless, low-power adjustment of the lens 3 in the height direction by utilizing the dynamic balance between elastic potential energy and external pressure through the mechanical collaborative design of the elastic part 521 and the pressing part 522.

[0071] According to embodiments of this application, such as Figure 6 As shown, the elastic part 521 provides an adaptive upward support force for the second adjustment mechanism 6, which counteracts the gravity of the lens 3 assembly and maintains positional stability. The pressing part 522 drives the lens 3 to move down precisely by applying controllable external pressure. After the pressure is released, the elastic part 521 automatically rebounds to achieve upward reset.

[0072] In one illustrative embodiment, such as Figure 6 As shown, the elastic part 521 is configured as a compression spring assembly. Multiple sets of helical compression springs are symmetrically arranged between the bottom of the second adjustment mechanism 6 and the guide rail 51. The spring stiffness is selected according to the weight matching of the lens 3 and the second adjustment mechanism 6, providing a uniform upward linear support force.

[0073] In an alternative embodiment, the elastic part 521 is in the form of an elastic pad array. The honeycomb pad group is formed by molding a highly elastic polymer (such as silicone or polyurethane) and filling it between the contact surface of the guide rail and the second adjustment mechanism 6. The nonlinear deformation characteristics of the material are used to absorb vibration and shock, and the regional adaptive adjustment of the support force is achieved by the gradient distribution of the pad thickness.

[0074] In another alternative embodiment, a sealed air chamber is integrated inside the guide rail 51, and the top of the chamber is connected to the second adjustment mechanism 6 via a piston; the air chamber is pre-filled with compressed gas to form an air cushion effect, providing support for the second adjustment mechanism 6.

[0075] In one illustrative embodiment, such as Figure 1 and Figure 2 As shown, the second adjustment mechanism 6 includes at least one second drive unit 61 and a transmission part 62; the second drive unit 61 is slidably disposed on the guide rail 51; the transmission part 62 is disposed on the second drive unit 61, the lens 3 is mounted on the transmission part 62, and is configured to move horizontally along the drive of the second drive unit 61 with the transmission part 62, so as to change the relative position of the lens 3 and at least two server bodies 2 in the horizontal direction.

[0076] According to the above configuration, the horizontal linkage design between the second drive unit 61 and the transmission unit 62 enables the horizontal positioning of the lens 3 when multiple server bodies 2 are arranged side by side.

[0077] In detail, the second drive unit 61 drives the transmission unit 62 to move the lens 3 in the horizontal direction, so that its first surface 31 can be accurately aligned with the indicator surface 21 of any target server body 2. Combined with the vertical adjustment function, the lens 3 can not only come into contact with the designated server body 2 to eliminate the refraction interference of the refrigerant 7, but also quickly switch the observation target.

[0078] Figure 5 A schematic diagram of the structure of the second drive unit according to an embodiment of this application is shown.

[0079] In one illustrative embodiment, such as Figure 2 and Figure 5As shown, the second adjustment mechanism 6 is provided with two second drive units 61, which are symmetrically arranged at both ends of the transmission part 62 in the horizontal direction. Each second drive unit 61 includes a winding roller 611 and an operating handle 612. The winding roller 611 is rotatably arranged in the lifting mechanism. The operating handle 612 is fixed to one end of the winding roller 611, allowing the user to manually drive the winding roller 611 to rotate. The transmission part 62 includes a flexible transmission belt 621, with both ends of the flexible transmission belt 621 wound around the circumference of the two winding rollers 611. The lens 3 is arranged in the straight area in the middle of the flexible transmission belt 621. When the two winding rollers 611 rotate in the same direction, the lens 3 is moved in the horizontal direction by winding and releasing the flexible transmission belt 621.

[0080] According to the above configuration, the user can manually rotate the operating handle 612 at the end to synchronously drive the winding roller 611 to rotate in the same direction. During the winding and unwinding process, the flexible transmission belt 621 drives the lens 3 to move smoothly in the horizontal direction, accurately covering the indicator surface 21 of any target server body 2. The symmetrical layout of the winding roller 611 eliminates the risk of off-center load due to single-sided drive, ensuring balanced tension of the transmission belt and no deviation in the movement trajectory of the lens 3. At the same time, the manual operation mode does not require a power supply and is suitable for explosion-proof or high electromagnetic interference environments.

[0081] In one illustrative embodiment, such as Figure 2 As shown, the operating handle 612 is located on the rotating shaft 613, and the rotating shaft is configured to extend to the outside of the housing, so that the user can manually operate the operating handle 612 located on the outside of the housing to adjust the position of the lens 3 in the horizontal direction when the housing 11 is in a closed state.

[0082] According to an embodiment of this application, the flexible transmission belt 621 includes a stainless steel belt with a polytetrafluoroethylene coating.

[0083] According to embodiments of this application, such as Figure 5 As shown, at least one end of the winding roller 611 is coaxially provided with a rotating shaft 613, and the winding roller 611 is rotatably mounted on the first adjusting mechanism 5 or located in the shaft mounting part of the first adjusting mechanism 5 via the rotating shaft 613.

[0084] According to an embodiment of this application, the end of the flexible transmission belt 621 can be fixed to the winding roller 611 by means of a groove provided in the circumference of the winding roller 611, or by means of bonding, fasteners or other methods.

[0085] In an alternative embodiment, the second adjustment mechanism 6 includes two symmetrically arranged stepper motors and a horizontal rack. The stepper motors are fixed on both sides of the first adjustment mechanism 5, and the rack meshes with the gear at the output end of the motor. The rack is driven by a synchronous controller to move the lens 3 along the horizontal guide rail, thereby achieving high-precision positioning and automated inspection, which is suitable for scenarios requiring remote control.

[0086] In another alternative embodiment, the second adjustment mechanism 6 adopts a combination of a manual handle and a horizontal lead screw. The handle drives the lead screw to rotate, and the nut assembly drives the lens 3 to move along the guide rail. Its self-locking characteristic ensures stable position, requires no additional energy, and is suitable for explosion-proof or low-power environments.

[0087] In another alternative embodiment, the second adjustment mechanism 6 drives the piston rod to extend and retract via a bidirectional pneumatic cylinder or hydraulic cylinder, thereby moving the lens 3 horizontally and controlling the valve group to adjust the pressure to achieve a rapid response. Its anti-electromagnetic interference characteristics make it suitable for high radiation or strong electromagnetic conditions.

[0088] Figure 6 The schematic diagram illustrates the structure of the box and cover according to an embodiment of this application.

[0089] In one illustrative embodiment, such as Figure 6 As shown, the cooling device also includes a cover 4, which is detachably disposed on the housing 1 to close the receiving cavity 11 when assembled on the housing 1; wherein the cover 4 has a viewing window 41, allowing the user to observe the lens 3 from outside the cover 4.

[0090] Based on the above configuration, by adding a removable cover 4 with a viewing window 41 to the top of the enclosure 1, closed-loop visual maintenance of the cooling device is achieved. The viewing window 41 of the cover 4 is directly aligned with the second surface 32 of the lens 3, allowing users to clearly observe the status of the indicator lights (such as blue / green lights) transmitted through the lens 3 without opening the cover 4. This avoids the risks of refrigerant 7 evaporation, contamination, and system heat dissipation imbalance caused by opening the cover in traditional solutions.

[0091] In detail, window 41 is made of a high-transmittance material, including tempered glass, polycarbonate, quartz glass and cyclic olefin polymer.

[0092] In one illustrative embodiment, the surface of the window 41 is also coated with a functional coating, including a hydrophobic coating (such as a fluorocarbon nanocoating) to reduce the adhesion of refrigerant 7 droplets and reduce visual interference; or an anti-fog coating to prevent fogging on the surface of the window 41 when the temperature changes abruptly and to maintain light transmission clarity.

[0093] In one illustrative embodiment, such as Figure 1 and Figure 2As shown, the pressing part 522 is configured to extend beyond the cover 4 through a through hole, so that the user can use the pressing part 522 to bring the lens 3 against the indicator surface 21 in the height direction and observe while the receiving cavity 11 is closed.

[0094] According to an embodiment of this application, the pressing part 522, through the extension design of the through hole in the cover body 4, realizes the integrated operation of non-contact adjustment and real-time observation of the lens 3 in the fully enclosed state of the receiving cavity 11.

[0095] In detail, the user can apply controllable pressure through the extended external pressure part 522 without opening the cavity, driving the lens 3 to move along the height direction, so that the first surface 31 abuts against the indicator surface 21 of the server body 2, and at the same time directly monitor the alignment status of the lens 3 through the transparent area of ​​the cover 4 or the integrated observation window.

[0096] In one illustrative embodiment, such as Figure 1 As shown, guide rails 51 are symmetrically arranged at both ends of the two winding rollers 611. The two ends of the winding rollers 611 are rotatably arranged in the guide grooves of the guide rails 51, either directly or indirectly through the rotating shafts 613 located at both ends, and can move along the extension direction of the guide rails 51. The elastic part 521 is arranged between the guide rails 51 and the periphery of the ends of the winding rollers 611 or the periphery of the rotating shafts 613.

[0097] Furthermore, a sliding block can be slidably provided inside the guide rail 51. The sliding block is rotatably connected to the winding roller 611 or the rotating shaft 613 through a bearing. Alternatively, the winding roller 611 or the rotating shaft 613 can be directly rotatably mounted on the through hole of the sliding block. The elastic part 521 is connected between the end of the guide rail 51 and the sliding block.

[0098] Figure 7 A schematic diagram of the structure of the pressing part according to an embodiment of this application is shown; Figure 8 The diagram schematically illustrates a structure in which the pressure portion is assembled onto the winding roller according to an embodiment of this application.

[0099] In one illustrative embodiment, such as Figure 7 and Figure 8 As shown, the pressing part 522 includes a connecting part 5221 sleeved on the winding roller 611 and a gripping part 5222 extending from the connecting part 5221 through a through hole on the cover 4 to the outside of the cover 4; wherein, the user can apply downward pressure to the winding roller 611 by gripping part 5222 when the box 1 is closed, so that the first surface 31 of the lens 3 abuts against the indicating surface 21 of the server body 2 for observation.

[0100] According to embodiments of this application, such as Figure 7 and Figure 8As shown, there are two connecting parts 5221, which are configured to be spaced apart along the axial direction of the winding roller 611 to form a guide channel that adapts to the width of the flexible transmission belt 621; the flexible transmission belt 621 can wrap around the winding roller 611 through the guide channel; the gripping part 5222 is configured to connect the two connecting parts 5221; wherein, the through hole on the cover 4 plays a guiding and limiting role for the gripping part 5222, preventing the pressing handle from rotating with the winding roller 611.

[0101] An embodiment of this application also provides an immersion server, including the above-mentioned cooling device and a server body 2. The server body 2 is disposed inside the housing 1 of the cooling device. The server body has an indicator surface 21, which is provided with at least one of the following: hard disk status light, hard disk fault light, network port status light, server identification light, and system fault light.

[0102] In detail, multiple types of status indicator lights are integrated on the indicator surface 21. Through the lens 3, which is adjusted in height for close observation, multi-dimensional visual diagnosis of the server body 2's hardware status and network connectivity can be achieved. Maintenance personnel can directly read key information such as hard drive operating status (e.g., read / write flashing / fault indicator light) and network connectivity (port signal synchronization) through the lens 3 without disassembling the equipment or connecting external testing tools.
