Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment, and more specifically, to an equipment cabinet, a server device including the equipment cabinet, and a cooling system including the equipment cabinet. Background Art

[0002] Currently, data center server equipment mainly uses the traditional method of cooling liquid directly input into the liquid cooling plate. High-power density chips are attached to the liquid cooling plate, and the heat is carried away by the cooling water circulating in the liquid cooling plate, thereby achieving the purpose of solving the high heat density.

[0003] In the process of realizing the present invention, the inventors discovered that the prior art has at least the following problems:

[0004] In the existing system, the cooling water interface of the liquid cooling plate is located in the core area of ​​computing power. If there are problems such as improper insertion or aging of the connector, the coolant is very likely to be sprayed into the core area of ​​computing power at the interface, directly damaging the server and causing an accident.

[0005] Therefore, how to effectively solve the problem of low safety in the equipment cavity is a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0006] In view of this, the first purpose of the present invention is to provide an equipment cabinet that can effectively solve the problem of low safety in the equipment cavity; the second purpose is to provide a server device including the above-mentioned equipment cabinet; and the third purpose is to provide a cooling system including the above-mentioned equipment cabinet.

[0007] In order to achieve the above first purpose, the present invention provides the following technical solutions:

[0011] A second heat exchanger is disposed in the heat exchange cavity, wherein the equipment cavity and the heat exchange cavity are separated by a partition to prevent liquid leaking from the second heat exchanger from entering the equipment cavity;

[0012] A heat conductor, wherein a first end of the heat conductor extends into the equipment cavity, and a second end extends into the heat exchange cavity and is in thermal contact with the second heat exchanger.

[0013] When in use, the high-heat-generating device in the equipment cavity is brought into thermal contact with the first end of the heat conductor, and the heat of the high-heat-generating device is transferred to the second heat exchanger through the heat conductor. At the same time, because the first heat exchanger and the second heat exchanger can pass through the cooling fluid, the first heat exchanger and the second heat exchanger can absorb heat and carry the heat out through the cooling fluid. At this time, the first heat exchanger dissipates heat for the entire cabinet cavity, and the second heat exchanger can dissipate heat for some of the heat-generating devices in the equipment cavity through the heat conductor. Moreover, since the equipment cavity and the heat exchange cavity are separated, the leakage generated at the second heat exchanger will be blocked by the partition and will not enter the equipment cavity, thereby achieving isolation and effectively protecting the equipment in the equipment cavity. When using the server, the computing core area of ​​the server can be placed in the equipment cavity to effectively increase the service life of the server. In summary, the equipment cabinet can effectively solve the problem of low safety in the equipment cavity.

[0018] In some technical solutions, it also includes an inlet, an outlet and a combination valve. In a first working state, the combination valve can enable the outlet of the first heat exchanger to bypass the second heat exchanger and connect to the inlet; in a second working state, the combination valve can enable the outlet of the first heat exchanger to connect to the inlet of the second heat exchanger.

[0019] In some technical solutions, the combination valve includes a two-way valve and a three-way valve; the outlet of the first heat exchanger is connected to the access port through the two-way valve; the inlet of the second heat exchanger is connected to the total outlet of the three-way valve; the outlet of the first heat exchanger is connected to the first inlet of the three-way valve, and the access port is connected to the second inlet of the three-way valve; the three-way valve has a first open state and a second open state; in the first open state, the first inlet and the total outlet of the three-way valve are closed, and the second inlet and the total outlet of the three-way valve are open; in the second open state, the first inlet and the second inlet are both open to the total outlet of the three-way valve.

[0020] In some technical solutions, when the two-way valve is closed and the three-way valve is in the second open state: the opening degree of the first inlet is 30%; and the opening degree of the second inlet is 70%.

[0021] In some technical solutions, the heat conductor is a flat-plate heat pipe; a plurality of the second heat exchangers are connected in parallel, and a switch valve is provided on the channel of each of the second heat exchangers.

[0030] The embodiment of the utility model discloses an equipment cabinet, which effectively solves the problem of low safety in the equipment cavity.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 2 , Figure 1 A schematic diagram of the structure of a server device provided in an embodiment of the present utility model; Figure 2 This is a schematic diagram of the connection of a heat exchanger in an equipment cabinet provided in an embodiment of the present utility model.

[0033] In some embodiments, an equipment cabinet is provided for storing electronic equipment, such as a server 9, a data storage device, and the like.

[0034] In some embodiments, the equipment cabinet mainly includes a cabinet body 1 , a first heat exchanger 2 , a second heat exchanger 3 and a heat conductor 4 .

[0035] Cabinet 1 has a cabinet chamber 1-3, which includes a device chamber 1-1 and a heat exchange chamber 1-2, separated by a partition. The partition prevents leaked cooling fluid from heat exchange chamber 1-2 from entering device chamber 1-1. Air can flow from heat exchange chamber 1-2 into device chamber 1-1 through partition 18, though air can also be blocked by partition 18.

[0036] In some specific applications, the first heat exchanger 2 is used to dissipate heat for the entire cabinet cavity 1-3, so the first heat exchanger 2 can be called a cabinet-level heat exchanger or a cabinet-level cooler; the second heat exchanger 3 is used to dissipate heat for electrical components with higher heating power, so the second heat exchanger 3 can be called a device-level heat exchanger or a device-level cooler.

[0037] In some embodiments, the first heat exchanger 2 is arranged at the air duct 1-4 of the cabinet cavity 1-3, that is, to dissipate heat from the cabinet cavity 1-3. The air duct 1-4 can be an air inlet or an air outlet. For example, in one heat dissipation method, if the first heat exchanger 2 is arranged at the air inlet of the cabinet cavity 1-3, when the external wind enters the cabinet cavity 1-3 from the air inlet, the heat of the external wind will be absorbed by the cooling fluid in the first heat exchanger 2 to reduce the temperature. The cooled wind enters the cabinet cavity 1-3 to absorb heat from the internal heating part to achieve cooling. Of course, when the cabinet 1 is in a larger chamber, at this time, the first heat exchanger 2 can be arranged at the air outlet of the cabinet cavity 1-3. After the wind outside the chamber enters the cabinet cavity 1-3, it absorbs heat and heats up, and then is discharged from the air outlet. When it is discharged from the air outlet, it is cooled again, and then enters the external chamber, and then can return to the air inlet again from the external chamber. This method can effectively prevent the cabinet cavity 1-3 from being too low in temperature. In order to facilitate the accelerated flow of air, a fan 16 is generally provided at the air inlet or the air outlet of the first heat exchanger 2 to accelerate the flow of air at the first heat exchanger 2 .

[0038] In some embodiments, the second heat exchanger 3 is disposed within the heat exchange chamber 1-2, with the equipment chamber 1-1 and heat exchange chamber 1-2 separated by a partition 18 to prevent liquid leaking from the second heat exchanger 3 from entering the equipment chamber 1-1, with or without preventing air flow. The partition may be a louver structure, or other barrier device that blocks splashing water while still allowing ventilation. During use, placing important electronic components within the equipment chamber 1-1 can prevent liquid from splashing into the equipment chamber 1-1 in the event of a leak from the second heat exchanger 3.

[0039] The first end of the heat conductor 4 extends into the equipment cavity 1-1, and the second end extends into the heat exchange cavity 1-2 and is in thermal contact with the second heat exchanger 3. The heat conductor 4 is capable of conducting heat between the first end and the second end. The heat conductor 4 can be a phase-change heat conducting element or a heat conducting entity with a relatively high thermal conductivity. When in use, the high-heat-generating device 17 is in thermal contact with the first end of the heat conductor 4, so that the heat conductor 4 absorbs heat from the high-heat-generating device 17 and then transfers it to the second end. At the second end, it is in thermal contact with the second heat exchanger 3, and then the heat is transferred to the second heat exchanger 3, and the second heat exchanger 3 carries the heat away. Through the heat conduction of the heat conductor 4, it is possible to avoid the second heat exchanger 3 being set in the equipment cavity 1-1, but the heat dissipation target in the equipment cavity 1-1, that is, the high-heat-generating component, can be cooled.

[0040] In some embodiments, during use, the high-heat-generating device 17 in the equipment cavity 1-1 is brought into thermal contact with the first end of the heat conductor 4. Heat from the high-heat-generating device 17 is transferred to the second heat exchanger 3 via the heat conductor 4. Simultaneously, because the first and second heat exchangers 2 and 3 can flow with cooling fluid, they can absorb heat and carry it away via the cooling fluid. In this case, the first heat exchanger 2 dissipates heat for the entire cabinet cavity 1-3, while the second heat exchanger 3, through the heat conductor 4, can dissipate heat specifically for certain heat-generating devices in the equipment cavity 1-1. Furthermore, because the equipment cavity 1-1 and the heat exchange cavity 1-2 are separated, leakage from the second heat exchanger 3 is blocked by the partition 18 and prevented from entering the equipment cavity 1-1. This achieves isolation and effectively protects the equipment in the equipment cavity 1-1. When using a server 9, the computing core of the server 9 can be placed in the equipment cavity 1-1, effectively extending the service life of the server 9. In summary, this equipment cabinet can effectively address the issue of low security in the equipment cavity 1-1.

[0041] In some embodiments, the first heat exchanger 2 can be a liquid-cooled backplane, and the second heat exchanger 3 can be a liquid-cooled cold plate. For example, for the liquid-cooled backplane, a relatively large air duct 1-4 can be formed on one side of the cabinet cavity 1-3 to serve as an air outlet or air inlet, with the first heat exchanger 2 placed flat on the air duct 1-4.

[0042] For example, for cabinet 1, an air outlet is formed on the rear side, facing the rear side, and has a large extension in the left-right and up-down directions. The corresponding liquid cooling back plate thickness direction is the front-to-back direction, and the corresponding liquid cooling back plate is matched with the air outlet so that all air outlets pass through the liquid cooling back plate. To facilitate the acceleration of air flow, multiple fans 16 can be arranged in the up-down direction. For example, two rows of fans 16 can be arranged in the left-right direction. Each row of fans 16 includes multiple fans 16 arranged in sequence along the up-down direction. The left and right rows of fans 16 can be aligned or staggered.

[0043] In some embodiments, the first heat exchanger 2, the heat exchange chamber 1-2, and the equipment chamber 1-1 are arranged horizontally in sequence. Compared to an up-and-down arrangement, this allows for greater utilization of space and facilitates uniform heat dissipation from the cabinet 1 in the vertical direction. This arrangement is particularly suitable for current server 9 equipment. Of course, other equipment cabinets can also be arranged in a vertical arrangement, as long as the height dimension is significantly greater than the front-to-back dimension.

[0044] In some embodiments, the first heat exchanger 2 is preferably located at the air outlet, that is, the equipment chamber 1-1, the heat exchange chamber 1-2, and the first heat exchanger 2 are arranged in sequence along the air outlet direction, and an exhaust fan 16 is provided at the heat exchanger. External air first enters the equipment chamber 1-1 to cool the entire chamber 1-1. The high-heating equipment in the equipment chamber 1-1 transfers heat to the second heat exchanger 3 through the heat conductor 4. After the air exits the equipment chamber 1-1, if the temperature is too high, it can first be absorbed by the second heat exchanger 3. If the temperature is too low, it can be cooled by the second heat exchanger 3 to better balance the air entering the first heat exchanger 2. After passing through the first heat exchanger 2, the higher-temperature air is cooled by the first heat exchanger 2 and then discharged into the enclosed room where the equipment cabinet is located. After the temperature of the enclosed room is controlled, it is prompted by the exhaust fan 16 to re-enter the equipment chamber 1-1 to continue cooling the equipment chamber 1-1.

[0045] In some embodiments, multiple shelves 1-5 may be arranged vertically in parallel within the equipment chamber 1-1. The vertical direction herein may be understood as the up-down direction or the height direction, i.e., the multiple shelves 1-5 are arranged vertically. Specifically, the equipment chamber 1-1 may also be provided with multiple second heat exchangers 3 arranged vertically in parallel, wherein the second heat exchangers 3 are arranged in a one-to-one correspondence with the shelves 1-5 to cool the equipment on the corresponding shelves 1-5.

[0046] When the equipment cabinet is used as a server, each shelf 1-5 will be installed with a corresponding small server 9, which can also be called a single server. Each small server 9 has high-power components with relatively high heat density, and each corresponding second heat exchanger 3 is used to centrally dissipate heat from these high-power components.

[0047] In some embodiments, the heat conductor 4 is preferably placed against the upper side of the corresponding second heat exchanger 3 to prevent the cooling fluid exposed on the second heat exchanger 3 from falling directly onto the heat conductor 4, thereby effectively preventing the cooling fluid from entering the equipment cavity 1-1 along the heat conductor 4.

[0048] When in use, the electronic device that is close to the heat conductor 4, that is, the cooling object of the heat conductor 4, can be set on the upper side of the electronic device, so that even if there is water column remaining on the heat conductor 4, it can be prevented from flowing to the corresponding electronic device.

[0049] In some embodiments, a water baffle may be provided on the lower side of the heat conductor 4, and the water baffle is located in the heat exchange chamber 1-2, or at the partition 18. The water baffle is used to prevent the liquid column suspended on the heat conductor 4 from flowing along the heat conductor 4 to the equipment chamber 1-1. When the liquid droplets flow along the heat conductor 4 to the equipment chamber 1-1, they are blocked by the downwardly extending water baffle when passing through the water baffle, so that they can only flow downward along the water baffle. When they flow to the water baffle, they cannot overcome gravity to flow upward and can only stay at the lower end of the water baffle. As the liquid droplets gather, the tension can no longer overcome gravity, causing the liquid droplets to fall. Since the water baffle is not located in the equipment chamber 1-1, the liquid droplets will not fall into the equipment chamber 1-1.

[0050] To better prevent the cooling fluid from flowing along the heat conductor 4 into the equipment chamber 1-1, a water baffle is preferably provided around the heat conductor 4. Of course, the water baffle is preferably provided in the heat exchange chamber 1-2. By providing the water baffle around the heat conductor 4, the liquid droplets can be prevented in both the vertical and horizontal directions.

[0051] In some embodiments, as with the first and second heat exchangers 2 and 3 described above, an external condenser is also required to introduce a low-temperature cooling fluid to dissipate heat. For this purpose, an inlet 5 and an outlet 6 are typically provided, allowing the first and second heat exchangers 2 and 3 to be arranged in series or in parallel between the inlet 5 and the outlet 6.

[0052] In some embodiments, a combination valve can be provided that can switch multiple connection states, with at least two operating states, which are referred to as a first operating state and a second operating state for ease of description. As shown in the accompanying drawings, in the first operating state, the combination valve can enable the outlet of the first heat exchanger 2 to bypass the second heat exchanger 3 and connect to the inlet 6, so that the first heat exchanger 2 and the second heat exchanger 3 are in a parallel state, so that the fluid flowing out of the outlet of the first heat exchanger 2 does not pass through the second heat exchanger 3 but flows directly to the inlet 6, thereby bypassing the second heat exchanger 3 but connecting to the inlet 6. In this case, generally, all of the cooling fluid flowing out of the outlet of the first heat exchanger 2 bypasses the second heat exchanger 3 and connects to the inlet 6. In the second operating state of the combination valve 7, the outlet of the first heat exchanger 2 is connected to the inlet of the second heat exchanger 3, so that the two are connected in series. At this time, part or all of the cooling fluid flowing out of the outlet of the first heat exchanger 2 flows to the second heat exchanger 3, and then flows to the inlet 6 after passing through the second heat exchanger 3. It should be noted that, in the second working state, of the cooling fluid flowing out of the outlet of the first heat exchanger 2, a part flows to the second heat exchanger 3, and the other part can bypass the second heat exchanger 3 through the above-mentioned combination valve to flow to the outlet 6. It should be noted that the combination valve can include two valve bodies, such as two switch valves. It can also include one valve body, such as a three-way valve 8 or a reversing valve, so as to meet the requirement that the cooling fluid flowing out of the first heat exchanger 2 can choose between passing through the second heat exchanger 3 and bypassing the second heat exchanger 3. At least for the proportion of the cooling fluid flowing out of the first cooler that flows to the second heat exchanger 3, the combination valve will be in the second working state than in the first working state, and the former proportion will be greater, that is, more cooling fluid will flow to the second heat exchanger 3.

[0053] When the temperature of the equipment cavity 1-1 is high, the first working state is selected for operation. When the temperature of the equipment cavity 1-1 is low, the second working state is selected for operation so that the cooling fluid flowing out of the outlet of the first heat exchanger 2 can enter the second heat exchanger 3 to cool down the higher-heating equipment in the second heat exchanger 3. Considering that the temperature difference between the ambient temperature of the equipment cavity 1-1 and the higher-heating equipment is not constant, and sometimes the difference is relatively large, at this time the temperature of the cooling fluid flowing out of the outlet of the first heat exchanger 2 will not be too high, at least equivalent to the higher-heating equipment, and cooling can be achieved. Then, the cooling fluid flowing out of the outlet of the first heat exchanger 2 is supplied to the second heat exchanger 3, which can effectively avoid the temperature of the cooling fluid at the inlet 6 being too low, and can achieve sufficient heat absorption and improve work efficiency. In summary, the internal unit of the cooling system can effectively solve the problem of poor working efficiency of the cooling system caused by changes in ambient temperature.

[0054] In some embodiments, the combined valve may include a two-way valve 7 and a three-way valve 8 , wherein the three-way valve 8 can be fully opened. Both the two-way valve 7 and the three-way valve 8 are electric valves to facilitate control by a controller.

[0055] The outlet of the first heat exchanger 2 is connected to the inlet 6 via a two-way valve 7. This establishes a parallel connection between the two-way valve 7 and the second heat exchanger 3. This means that the cooling fluid entering the two-way valve 7 at the outlet of the first heat exchanger 2 bypasses the second heat exchanger 3 and flows directly to the inlet 6.

[0056] The inlet of the second heat exchanger 3 is connected to the main outlet of the three-way valve 8; the outlet of the first heat exchanger 2 is connected to the first inlet of the three-way valve 8, and the access port 5 is connected to the second inlet of the three-way valve 8. The three-way valve 8 has a first open state and a second open state. In the first open state, the connection between the first inlet and the main outlet of the three-way valve 8 is closed, while the connection between the second inlet and the main outlet of the three-way valve 8 is open, preventing the cooling fluid flowing out of the outlet of the first heat exchanger 2 from flowing to the second heat exchanger 3. In the first open state, the corresponding two-way valve 7 is open, and the combination valve is in the first operating state, allowing the cooling fluid flowing out of the outlet of the first heat exchanger 2 to bypass the second heat exchanger 3 and flow to the access port 6. In the second open state, the connection between the first inlet and the second inlet and the main outlet of the three-way valve 8 is open, allowing the cooling fluid flowing out of the outlet of the first heat exchanger 2 to flow to the second heat exchanger 3, and allowing some of the cooling fluid flowing into the access port 5 to flow directly through the three-way valve 8 to the second heat exchanger 3. The three-way valve 8 is in the second open state, and the corresponding two-way valve 7 is closed. At this time, the combination valve is in the second working state, and the cooling fluid flowing out of the outlet of the first heat exchanger 2 all enters the second heat exchanger 3 through the first inlet.

[0057] In some embodiments, the three-way valve 8 can be configured to have at least one open state: the opening of the first inlet is smaller than the opening of the second inlet, as specifically described in the second open state. This ensures that, in the second open state, the cooling fluid at the inlet 5 is partially forced to flow to the first heat exchanger 2, rather than all of it flowing directly to the first heat exchanger 2. In this case, the three-way valve 8 also acts as a diverter. Specifically, this can be achieved by reducing the diameter of the second inlet. The smaller the diameter of the second inlet, the greater the resistance, thereby forcing more cooling fluid to enter the first heat exchanger 2 and then flow to the second heat exchanger 3.

[0058] When the combination valve is in the second working state, the two-way valve 7 is closed, and the corresponding three-way valve 8 is in the second open state, the opening degree of the first inlet can be made about 30%, such as between 20% and 40%, so that the cooling fluid entering the second heat exchanger 3 comes more directly from the inlet 5 and less from the first heat exchanger 2, so as to ensure heat dissipation for higher heat generation equipment.

[0059] In some embodiments, when the two-way valve 7 is closed and the three-way valve 8 is in the second open state, the first inlet can be opened at 30% and the second inlet can be opened at 70%, so that 30% of the cooling fluid entering the second heat exchanger 3 comes from the first heat exchanger 2, and the remaining 70% comes directly from the inlet 5. In some cases, 30% of the cooling fluid flowing out of the inlet 5 can flow through the first heat exchanger 2 to the second heat exchanger 3, while the remaining 70% bypasses the first heat exchanger 2 and flows directly to the second heat exchanger 3.

[0060] In some embodiments, the heat conductor 4 can be a flat heat pipe, and the second heat exchanger 3 can be a liquid-cooled cold plate. The liquid-cooled cold plate and the flat heat pipe are arranged in a one-to-one correspondence and transfer heat. The liquid-cooled cold plate includes a plate body and a cooling fluid channel opened in the plate body to connect between the three-way valve 8 and the inlet 6. The flat heat pipe exchanges heat between the plate body and the cooling fluid channel. The flat heat pipe can be a micro-nano heat pipe, and its specific structure can refer to the existing technology. When in use, the flat heat pipe and the corresponding heating device (electronic chip, etc.) are in thermal contact to absorb heat. Then, at the second heat exchanger 3, the flat heat pipe and the liquid-cooled cold plate are in direct thermal contact, so that the heat absorbed by the flat heat pipe from the heating device is transferred to the liquid-cooled cold plate, and then transferred out by the liquid-cooled cold plate. The flat heat pipe is generally a phase change heat exchanger.

[0061] In some embodiments, multiple second heat exchangers 3 can be connected in parallel. In this case, a switch valve is provided on the channel of each second heat exchanger 3. Specifically, a switch valve can be provided at the outlet of the second heat exchanger 3.

[0062] In some embodiments, a first three-way structure 10 is further included, the inlet of the first three-way structure 10 is connected to the access port 5, and a first exhaust valve 12 is arranged between them, and one outlet of the first three-way structure 10 is connected to the second inlet of the above-mentioned three-way valve 8, and a first temperature sensor 13 is arranged between them.

[0063] In some embodiments, a second three-way structure 11 is further included. One inlet of the second three-way structure 11 is connected to the outlet of the second heat exchanger 3. Preferably, the outlets of the second heat exchangers 3 are combined to form a confluence. The confluence is connected to one inlet of the second three-way structure 11, with a second temperature sensor 15 and a second exhaust valve 14 disposed therebetween. The other inlet of the second three-way structure 11 is connected to the two-way valve 7, while the total outlet is connected to the inlet 6. Generally, both the inlet 5 and the outlet 6 are equipped with on / off valves.
