Description

Technical Field

[0001] The present application relates to the technical field of server cooling, and more specifically, to a cooling device and an immersion cooling device. Background Art

[0002] Liquid cooling technology is widely used in the server field due to its efficient heat dissipation capabilities. Immersion liquid cooling immerses the entire server body in a specific refrigerant, using the flow and phase change of the refrigerant to achieve rapid heat dissipation, significantly improving heat dissipation efficiency and reducing energy consumption.

[0003] However, during operation, the server body needs to use the indicator lights on the body (such as hard disk status light, fault light, network status light, etc.) to provide real-time feedback on the device status, and the immersion liquid cooling environment greatly reduces the visibility of such indicator lights. At present, cooling devices usually use a transparent observation window design, but the refraction effect of the refrigerant causes the light path to shift, making it impossible for operation and maintenance personnel to accurately identify the indicator light status through the observation window. In addition, if the cover is opened frequently for inspection, it may not only cause refrigerant contamination or gasification loss, but may also cause a decrease in the heat dissipation stability of the equipment, and even cause safety hazards due to refrigerant leakage. This problem is particularly prominent in computer room inspections, health checks, and fault location scenarios, which directly affects operation and maintenance efficiency and equipment reliability.

[0051] Below, embodiments of the present application will 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 the present application. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present application.

[0055] Figure 1 A schematic diagram showing a structure of a cooling device according to an embodiment of the present application in a front view direction; Figure 2 A schematic diagram showing a structure of a cooling device according to an embodiment of the present application when viewed from above; Figure 3 The diagram schematically shows the path of light on the indicating surface of the server body when a lens is provided according to an embodiment of the present application.

[0056] The embodiment of the present application provides a cooling device, such as Figures 1 to 3 As shown, it includes a box body 1 and a lens 3. The box body 1 defines a accommodating cavity 11, and the accommodating cavity 11 is configured with a server body 2 and a refrigerant 7 immersed in the server body 2, and the server body 2 has an upwardly arranged indicating surface 21; the lens 3 is arranged in the accommodating cavity 11, including a first surface 31 facing the server body 2 and a second surface 32 opposite to the first surface 31, and the second surface 32 is exposed above the liquid surface of the refrigerant 7; wherein the lens 3 has a first state in which the first surface 31 is in contact with the indicating surface 21, and a second state in which the first surface 31 is separated from the indicating surface 21.

[0057] According to the above-mentioned setting method, the switchable design of the lens 3 between the first state (abutting the indicating surface 21) and the second state (detaching from the indicating surface 21) effectively solves the observation problem of the indicator light of the server body 2 in the immersion liquid cooling environment due to the refraction / scattering of the refrigerant 7. In the first state, the lens 3 is in direct contact with the indicating surface 21, eliminating the interference of the refrigerant 7 on the light path, so that the light of the indicator light (such as blue and green short-wavelength light sources) passes directly through the liquid surface through the lens 3 to achieve distortion-free observation; in the second state, the lens 3 is separated from the indicating surface 21 to ensure that the flow space of the refrigerant 7 is not blocked and the heat dissipation efficiency is maintained. It takes into account the dual needs of efficient heat dissipation and status visualization, and the indicator light status can be accurately identified without opening the cover, avoiding the risk of refrigerant 7 contamination and thermal runaway, and significantly improving the operation and maintenance safety and equipment maintainability.

[0058] In an illustrative embodiment, Figure 1 and Figure 2 As shown, there is at least one server body 2 in the accommodating cavity 11; the cooling device also includes a first adjusting mechanism 5, the lens 3 is arranged on the first adjusting mechanism 5, and is configured to move along the height direction with the first adjusting mechanism 5, so that the lens 3 abuts against the indicating surface 21 along the height direction, or detaches from the indicating surface 21.

[0059] According to the above-mentioned setting method, 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 indication surface 21 of the server body 2, eliminating the refraction and scattering effects of the refrigerant 7 on the indicator light, ensuring high-fidelity transmission of short-wavelength signals, and allowing operation and 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 is separated from the indication surface 21, and the refrigerant 7 refills the gap, avoiding the increase of local thermal resistance caused by contact, and maintaining the overall heat dissipation performance of the liquid cooling system.

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

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

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

[0063] In detail, the second adjustment mechanism 6 drives the lens 3 to move in the horizontal direction so that it covers the upper portion of the indication surface 21 of any target server body 2. Combined with the vertical lifting function of the first adjustment mechanism 5, the lens 3 can be quickly switched to abut against or disengage from the indication surface 21 of the target server body 2. This solves the observation problem caused by the dispersed positions 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 body 2, significantly improving the operation and maintenance efficiency of high-density data centers.

[0064] Figure 4 The enlarged view of the structure of the guide rail according to the embodiment of the present application is schematically shown.

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

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

[0067] According to an embodiment of the present application, the guide rail 51 rigidly extends in 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 as needed to the relative height with the indication surface 21 of the server body 2, thereby facilitating 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 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 an illustrative embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the first driving unit 52 includes at least one elastic portion 521 and at least one pressing portion 522; the elastic portion 521 is arranged between the guide rail 51 and the second adjusting mechanism 6, and is configured to apply an upward supporting force to the second adjusting mechanism 6; the pressing portion 522 is connected to the second adjusting mechanism 6, and is configured to apply downward pressure to the second adjusting mechanism 6 through an external force; wherein, by adjusting the pressure, the second adjusting mechanism 6 drives the lens 3 to move in the height direction.

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

[0071] According to the embodiments of the present application, Figure 6 As shown, the elastic part 521 provides an adaptive upward supporting force for the second adjustment mechanism 6, offsetting the gravity of the lens 3 assembly and maintaining position stability, while the downward pressing part 522 drives the lens 3 to move downward precisely by applying controllable external pressure. After the pressure is released, the elastic part 521 automatically rebounds to achieve upward reset.

[0072] In an illustrative embodiment, Figure 6 As shown, the elastic portion 521 is configured as a compression spring group, and multiple groups 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 to provide uniform upward linear support force.

[0073] In an alternative embodiment, the elastic portion 521 is in the form of an elastic gasket array, which is molded into a honeycomb gasket group using a highly elastic polymer (such as silicone or polyurethane) and filled 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 shocks, and regional adaptive adjustment of the supporting force is achieved through the gradient distribution of the gasket thickness.

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

[0075] In an illustrative embodiment, Figure 1 and Figure 2 As shown, the second adjustment mechanism 6 includes at least one second driving unit 61 and a transmission part 62; the second driving unit 61 is slidably arranged on the guide rail 51; the transmission part 62 is arranged on the second driving unit 61, and the lens 3 is installed on the transmission part 62, and is configured to move in the horizontal direction with the transmission part 62 under the drive of the second driving unit 61 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 arrangement, through the horizontal linkage design of the second driving unit 61 and the transmission part 62, the horizontal positioning of the lens 3 is achieved when multiple server bodies 2 are arranged side by side.

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

[0078] Figure 5 The structure of the second driving unit according to the embodiment of the present application is schematically shown.

[0079] In an illustrative embodiment, Figure 2 and Figure 5As shown, the second adjustment mechanism 6 is provided with two second driving units 61, and the two second driving units 61 are symmetrically arranged at the two ends of the transmission part 62 in the horizontal direction, and each second driving unit 61 includes a winding roller 611 and an operating handle 612; the winding roller 611 is rotatably arranged on the lifting mechanism; the operating handle 612 is fixed to one end of the winding roller 611, so that the user can manually drive the winding roller 611 to rotate; the transmission part 62 includes a flexible transmission belt 621, and the two ends of the flexible transmission belt 621 are respectively wound around the circumference of the two winding rollers 611, and the lens 3 is arranged in the straight area in the middle of the flexible transmission belt 621; wherein, when the two winding rollers 611 rotate in the same direction, the flexible transmission belt 621 is wound and released to drive the lens 3 to move in the horizontal direction.

[0080] According to the above-mentioned setting method, the user manually rotates the operating handle 612 at the end to synchronously drive the winding roller 611 to rotate in the same direction. The flexible transmission belt 621 drives the lens 3 to move smoothly in the horizontal direction during the winding and releasing process, accurately covering the upper part of the indication surface 21 of any target server body 2; the symmetrical layout of the winding roller 611 design eliminates the risk of overloading of one-sided drive, ensures the balanced tension of the transmission belt and the non-deviation of the moving trajectory of the lens 3, and the manual operation mode does not require power supply, which is suitable for explosion-proof or high electromagnetic interference environment.

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

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

[0083] According to the embodiments of the present application, Figure 5 As shown, at least one axial 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 adjustment mechanism 5 or located in the shaft mounting portion of the first adjustment mechanism 5 via the rotating shaft 613 .

[0085] In a replaceable embodiment, the second adjustment mechanism 6 includes two symmetrically arranged stepper motors and horizontal racks.

The racks are driven by a synchronous controller to drive the lens 3 to move along the horizontal guide rail, thereby achieving high-precision positioning and automated inspection, which is suitable for scenarios requiring remote control.

[0086] In another replaceable embodiment, the second adjustment mechanism 6 adopts a combination of a manual handle and a horizontal screw. The handle drives the screw to rotate, and the nut assembly drives the lens 3 to translate along the guide rail. Its self-locking feature ensures a stable position, does not require additional energy, and is suitable for explosion-proof or low-power consumption environments.

[0087] In another alternative embodiment, the second adjustment mechanism 6 drives the piston rod to extend and retract through a bidirectional pneumatic cylinder or hydraulic cylinder, thereby driving the lens 3 to move horizontally. The control valve group adjusts the pressure to achieve rapid response, and its anti-electromagnetic interference properties make it suitable for high radiation or strong electromagnetic working conditions.

[0090] According to the above-mentioned setting mode, by adding a detachable cover 4 with a window 41 on the top of the box body 1, closed visual operation and maintenance of the cooling device is realized. The window 41 of the cover body 4 is directly aligned with the second surface 32 of the lens 3, and the user can clearly observe the state of the indicator light (such as blue / green light) transmitted by the lens 3 through the window 41 without opening the cover body 4, avoiding the risk of volatilization and contamination of the refrigerant 7 and imbalance of system heat dissipation caused by opening the cover in the traditional solution.

[0091] In detail, the window 41 is made of a highly light-transmitting material, including one of tempered glass, polycarbonate, quartz glass and cycloolefin polymer.

[0092] In an illustrative embodiment, the surface of the window 41 is also coated with a functional coating, including a liquid-repellent coating (such as a fluorocarbon nano-coating) that can 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 suddenly, thereby maintaining light clarity.

[0093] In an illustrative embodiment, Figure 1 and Figure 2As shown, the pressing portion 522 is configured to extend outside the cover body 4 through the through hole on the cover body 4, so that the user can make the lens 3 abut against the indicating surface 21 along the height direction through the pressing portion 522 when the accommodating cavity 11 is in a closed state and observe.

[0094] According to the embodiment of the present application, the pressing portion 522 realizes the integrated operation of contactless adjustment of the height of the lens 3 and real-time observation when the accommodating cavity 11 is fully closed through the extension design of the through hole of the cover body 4 .

[0095] In detail, the user can apply controllable pressure by extending to the external downward pressure portion 522 without opening the cavity, driving the lens 3 to move in the height direction so that the first surface 31 abuts against the indication 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 body 4 or the integrated observation window.

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

[0098] Figure 7 The structure diagram of the pressing part according to the embodiment of the present application is schematically shown; Figure 8 The structure diagram of the pressing portion assembled on the winding roller according to the embodiment of the present application is schematically shown.

[0099] In an illustrative embodiment, Figure 7 and Figure 8 As shown, the downward pressing portion 522 includes a connecting portion 5221 sleeved on the winding roller 611 and a holding portion 5222 extending from the connecting portion 5221 through the through hole on the cover body 4 to the outside of the cover body 4; wherein, the user can apply downward pressure to the winding roller 611 through the holding portion 5222 when the box body 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.
