Description

Technical Field

[0001] This utility model relates to the field of liquid-cooled cabinet testing technology, specifically to a liquid-cooled dummy load testing device and a liquid-cooled cabinet. Background Technology

[0002] Before being put into use, liquid-cooled cabinets need to undergo operational testing. Operational monitoring mainly includes heat dissipation performance testing, server load testing, and system compatibility stress testing to obtain various boundary data. This data is used to verify and evaluate the heat dissipation effect, performance stability, energy efficiency, compatibility, and safety of the liquid cooling system, while ensuring that the system can maintain a high-efficiency and reliable operating state under various load and environmental conditions.

[0003] During testing, in order to make the test results close to the limit boundary value and the reality, there are situations where the server runs under high load for a long time. During long-term testing, the server is often under high load, and the processor and other hardware components generate a lot of heat.

[0004] The existing testing equipment contains a fixed number of heat-generating components, making it difficult to adjust the heat generation efficiency and simulate the heat dissipation efficiency under different conditions. Utility Model Content

[0005] This invention aims to address one of the technical problems in related technologies to a certain extent. To this end, this invention provides a liquid-cooled dummy load testing device and a liquid-cooled cabinet, which has the advantages of adjustable heating power and meeting different application requirements.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A liquid-cooled dummy load testing device includes a frame and a heating unit. The frame includes a top plate, a bottom plate, and opposing side plates, which surround and form a receiving space for accommodating the heating unit. The liquid-cooled dummy load testing device further includes a fixing unit and a control unit. The fixing unit includes at least one set of fixing brackets, which are fixedly connected to the frame and used to fix the heating unit to the inner wall of the frame. The heating unit includes multiple heating elements, and multiple heating element fixing holes are formed on the fixing unit. The heating elements are detachably mounted on the fixing unit through the heating element fixing holes and are clamped to the inner side of the fixing unit. The control unit is disposed on the outer wall of the frame and includes a control component that passes through the frame and is electrically connected to the heating elements, and is used to control the power of the heating elements. By using heating elements installed within the dummy load as a substitute for the real server during testing, damage to the real server is avoided, and testing costs are reduced. In the dummy load, multiple heating elements are fixed to the heating element mounting holes of the fixed unit. The heating power of the dummy load can be changed by adjusting the number of heating elements installed to meet the heating requirements of different usage environments and achieve a wider range of applicability.

[0008] Optionally, the number of fixing brackets is multiple sets, and each set of fixing brackets includes at least two fixing plates. The two ends of each fixing plate are respectively fixed to the inner wall of the side plate. A set of fixing brackets is symmetrically arranged on both sides of the frame along a first direction, which is perpendicular to the side plate. The fixing plates are used to fix the heating element, and two symmetrically arranged fixing plates are distributed.

[0009] Optionally, the top plate is fixedly connected to the two side plates at both ends along the first direction, and the extension direction of the fixing plate is parallel to the top plate of the frame. The parallel extension direction of the fixing plate to the top plate ensures that the heating elements are neatly arranged, saving space and allowing more heating elements to be installed within the frame, thereby increasing the simulation range.

[0010] Optionally, the heating element fixing holes are located on the fixing plate, and are evenly distributed along the length of the fixing plate, penetrating the fixing plate. The even distribution of the heating element fixing holes along the fixing plate ensures equal spacing between the heating elements mounted on the fixing plate, thereby improving their heat dissipation performance.

[0011] Optionally, the heating element is provided with a heating element mounting hole and a heating element mounting member. The heating element mounting hole penetrates the heating element in the direction toward the fixing plate, and the heating element mounting member passes through the heating element mounting hole and the heating element fixing hole to fix the heating element to the fixing plate. The heating element mounting hole and the heating element mounting member on the heating element are used to mate with the heating element fixing hole on the fixing plate to install the heating element on the fixing plate. This method of installing the heating element has the advantages of stable installation and convenient disassembly and assembly. It allows the heating element to be disassembled and assembled to adjust the number of heating elements when needed, thereby adjusting the simulation performance, and has the advantages of flexibility.

[0012] Optionally, the side plate is provided with multiple fixing bracket holes, which are evenly distributed along the extension direction of the side plate. The two ends of the fixing plate are provided with fixing plate mounting holes and fixing plate mounting components. The fixing plate mounting holes penetrate the fixing plate along a second direction, which is perpendicular to the first direction. The fixing plate mounting components penetrate the fixing plate mounting holes and the fixing bracket mounting holes, and install the fixing plate on the side plate. Both ends of the fixing plate are fixed to the side plate through the fixing bracket holes. The multiple fixing bracket holes on the side plate are used to cooperate with the fixing plate mounting holes and fixing plate mounting components on the fixing plate to fix both ends of the fixing plate at the same horizontal position on the side plate, ensuring stable installation and fixation of the fixing plate, and keeping the heating elements fixed to the fixing plate neatly arranged.

[0013] Optionally, the flow guiding unit includes a first flow guiding port and a second flow guiding port. The flow guiding unit connects the receiving space and the outside of the frame. The first flow guiding port is located at a first end of the frame and is used to receive coolant flowing into the cooling space. The second flow guiding port is located at a second end of the frame and is used to receive coolant flowing out of the cooling space. The receiving space is filled with coolant. The coolant flows into the receiving space through the first coolant, flows past the heat-generating component, and then leaves the receiving space through the second flow guiding port. Immersion liquid cooling can achieve better heat dissipation, extend the service life of the heat-generating component, and reduce operating costs.

[0014] Optionally, the top of the side plate is provided with a lifting lug, and a lifting hole is formed on the lifting lug, the lifting hole penetrating the lifting lug. The lifting lug and the lifting hole on the lifting lug are used to facilitate the lifting of the liquid-cooled dummy load testing device during transportation or installation, making the liquid-cooled dummy load testing device easier to handle or install.

[0015] Optionally, the control unit further includes a switch, and the switch and the control unit are disposed on the top plate. The top plate has a control unit mounting hole. The control unit includes a control end and a connecting end fixedly connected. The control end passes through the control unit mounting hole and protrudes from the top plate. The control end is rotatable within the control unit mounting hole. The connecting end is located within the receiving space and is electrically connected to the heating element. By rotating the control end of the control unit, the heating power of the heating element can be changed, allowing for convenient and quick modification of the heating simulation parameters during testing, thus facilitating testing.

[0016] Furthermore, this utility model also provides a liquid-cooled server rack for accommodating servers, including the liquid-cooled dummy load testing device described in any of the preceding claims. The server rack forms a server space that matches the volume of the server and is used to accommodate it. The liquid-cooled dummy load testing device is the same size as the server. The reasoning process for the beneficial effects of the liquid-cooled server rack provided by this utility model and the aforementioned liquid-cooled dummy load testing device is similar and will not be repeated here.

The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0025] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0026] Example:

[0027] like Figure 1As shown, a liquid-cooled dummy load testing device includes a frame 1 and a heating unit 2. The frame 1 includes a top plate 11, a bottom plate 12, and opposing side plates 13. The bottom plate 12, top plate 11, and side plates 13 surround and form a receiving space 14 for accommodating the heating unit 2. The liquid-cooled dummy load testing device also includes a fixing unit 3 and a control unit 4. The fixing unit 3 includes at least one set of fixing brackets 31. The fixing unit 3 is fixedly connected to the frame 1 and is used to fix the heating unit 2 to the inner wall of the frame 1. The heating unit 2 includes multiple heating elements 21. Multiple heating element fixing holes 312 are formed on the fixing unit 3. The heating elements 21 are detachably mounted on the fixing unit 3 through the heating element fixing holes 312 and are clamped inside the fixing unit 3. The control unit 4 is disposed on the outer wall of the frame 1. The control unit 4 includes a control element 41. The control element 41 passes through the frame 1 and is electrically connected to the heating elements 21, and is used to control the power of the heating elements 21. By using the heating element 21 set in the accommodating space 14 as a substitute for the real server for testing, damage to the real server is avoided and testing costs are reduced. In the dummy load, multiple heating elements 21 are fixed on the heating element fixing holes 312 of the fixing unit 3. The heating power of the dummy load can be changed by adjusting the number of heating elements 21 installed to meet the heating requirements of different usage environments and obtain a wider range of applications.

[0028] The number of fixing brackets 31 is multiple sets, and each set of fixing brackets 31 includes at least two fixing plates 311. The two ends of the fixing plates 311 are respectively fixed to the inner wall of the side plate 13. A set of fixing brackets 31 is symmetrically arranged on both sides of the frame 1 along a first direction X, which is perpendicular to the side plate 13. The fixing plates 311 are used to fix the heating element 21, and two symmetrically arranged fixing plates 311 are distributed.

[0029] The top plate 11 is fixedly connected to the two side plates 13 at both ends along the first direction X, and the extension direction of the fixing plate 311 is parallel to the top plate 11 of the frame 1. The extension direction of the fixing plate 311 is parallel to the top plate 11, so that the heating elements 21 are fixedly and neatly arranged, saving space and allowing more heating elements 21 to be installed in the frame 1, thereby increasing the simulation range.

[0030] The heating element fixing holes 312 are located on the fixing plate 311 and are evenly arranged along the length of the fixing plate 311, penetrating the fixing plate 311. The even arrangement of the heating element fixing holes 312 along the fixing plate 311 ensures that the spacing between the heating elements 21 installed on the fixing plate 311 is equal, thereby improving their heat dissipation performance.

[0031] The heating element 21 is provided with a heating element mounting hole 211 and a heating element mounting member 212. The heating element mounting hole 211 penetrates the heating element 21 in the direction toward the fixing plate 311. The heating element mounting member 212 passes through the heating element mounting hole 211 and the heating element fixing hole 312 to fix the heating element 21 onto the fixing plate 311. The heating element mounting hole 211 and the heating element mounting member 212 on the heating element 21 are used to cooperate with the heating element fixing hole 312 on the fixing plate 311 to install the heating element 21 onto the fixing plate 311. This method of installing the heating element 21 has the advantages of stable installation and convenient disassembly and assembly. It allows the heating element 21 to be disassembled and assembled as needed to adjust the number of heating elements 21, thereby adjusting the simulation performance, which has the advantages of flexibility.

[0032] like Figure 3 As shown, in another embodiment of this application, the heating element mounting hole 211 can also penetrate the heating element 21 in the direction toward the side plate 13. The opening direction of the heating element fixing hole 312 is the same as that of the heating element mounting hole 211. The heating element mounting member 212 passes through the heating element mounting hole 211 and the heating element fixing hole 312 to fix the heating element 21 onto the fixing plate 311 (not shown in the figure). The heating element fixing hole 312 is located on a protrusion protruding from the fixing plate 311 toward the receiving space 14.

[0033] The side plate 13 is provided with a plurality of fixing bracket holes 131, which are evenly distributed along the extension direction of the side plate 13. The two ends of the fixing plate 311 are provided with fixing plate 311 mounting holes and fixing plate mounting members 313. The fixing plate 311 mounting holes penetrate the fixing plate 311 along a second direction Y, which is perpendicular to the first direction X. The fixing plate mounting members 313 penetrate the fixing plate 311 mounting holes and the fixing bracket 31 mounting holes, and install the fixing plate 311 onto the side plate 13. The two ends of the fixing plate 311 are fixed to the side plate 13 through the fixing bracket holes 131. The plurality of fixing bracket holes 131 on the side plate 13 are used to cooperate with the fixing plate 311 mounting holes and fixing plate mounting members 313 to fix the two ends of the fixing plate 311 at the same horizontal position on the side plate 13, so that the fixing plate 311 can be stably installed and fixed, and the heating element 21 fixed on the fixing plate 311 can also remain neat.

[0034] like Figure 2As shown, the flow guiding unit 5 includes a first flow guiding port 51 and a second flow guiding port 52. The flow guiding unit 5 connects the accommodating space 14 and the outside of the frame 1. The first flow guiding port 51 is located at the first end of the frame 1 and is used to accommodate coolant flowing into the cooling space. The second flow guiding port 52 is located at the second end of the frame 1 and is used to accommodate coolant flowing out of the cooling space. The accommodating space 14 is filled with coolant. The coolant flows into the accommodating space 14 through the first coolant, flows past the heat-generating element 21, and then leaves the accommodating space 14 through the second flow guiding port 52. Immersion liquid cooling can achieve better heat dissipation, extend the service life of the heat-generating element 21, and reduce operating costs.

[0035] The top of the side plate 13 is provided with a lifting lug 132, and a lifting hole 1321 is formed on the lifting lug 132, which penetrates through the lifting lug 132. The lifting lug 132 and the lifting hole 1321 provided on the lifting lug 132 are used to facilitate the lifting of the liquid-cooled dummy load testing device during transportation or installation, so that the liquid-cooled dummy load testing device can be handled or installed more conveniently.

[0036] like Figure 3 As shown, in another embodiment of this application, the lifting lug 132 does not have the lifting hole 1321, but the lifting lug 132 and the top plate 11 surround to form a lifting space, and the liquid-cooled dummy load test device is lifted through the lifting space during lifting.

[0037] The control unit 4 further includes a switch 42. The switch 42 and the control unit 41 are disposed on the top plate 11. The top plate 11 has a mounting hole for the control unit 41. The control unit 41 includes a control end 411 and a connecting end 412 fixedly connected. The control end 411 passes through the mounting hole and protrudes from the top plate 11. The control end 411 is rotatable within the mounting hole. The connecting end 412 is located within the receiving space 14 and is electrically connected to the heating element 21. By rotating the control end 411 of the control unit 41, the heating power of the heating element 21 can be changed, allowing for convenient and quick modification of the heating simulation parameters during testing, thus facilitating testing.

[0038] Furthermore, this utility model also provides a liquid-cooled server rack for accommodating servers, including the liquid-cooled dummy load testing device described in any of the preceding claims. The server rack forms a server space that matches the volume of the server and is used to accommodate it. The liquid-cooled dummy load testing device is the same size as the server. The reasoning process for the beneficial effects of the liquid-cooled server rack provided by this utility model and the aforementioned liquid-cooled dummy load testing device is similar and will not be repeated here.
