TECHNICAL FIELD

[0001] The utility model relates to the field of electronic equipment liquid cooling, more particularly to a temperature exchange unit and device. BACKGROUND

[0002] Electronic equipment includes some high-power components and the like that generate a large amount of heat during operation. If this heat is not promptly and effectively dissipated, the equipment will overheat, affecting performance and even damaging hardware. Therefore, liquid cooling technology is needed to cool electronic equipment. The current mainstream liquid cooling technology route includes cold plate type, immersion type, and spraying type, and one or more of the liquid cooling technology is used in a liquid cooling cabinet to achieve cooling of electronic equipment. The current mainstream liquid cooling cabinet uses a liquid inlet pipe and a liquid return pipe to jointly transport and drain the temperature exchange medium. However, this approach has the following disadvantages: first, the cabinet installs multiple liquid cooling equipment nodes to cool multiple electronic devices, requiring a large number of connection liquid inlet and return pipes, complex pipelines, and large space occupation; second, the use of liquid cooling medium converges from numerous branch pipes to the main liquid pipe, resulting in a large pressure in the main liquid pipe, increased maintenance cost of the main liquid pipe, and reduced flow rate of the main liquid pipe. Therefore, the liquid cooling medium drainage scheme needs to be adjusted. SUMMARY

Detailed Implementation

[0054] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product; it is understandable to those skilled in the art that some well-known devices and their descriptions may be omitted in the drawings.

[0055] Example

[0056] This invention provides a temperature-switching unit. For example... Figure 1 The diagram shows a side view of a temperature exchange unit according to this invention. The temperature exchange unit includes a frame 4, a temperature exchange device node 11, and a temperature exchange medium circulation system. The temperature exchange device node 11 is installed inside the frame 4. The temperature exchange device node 11 is mounted via an installation structure provided inside the frame 4. Preferably, the installation structure can be a slot; it is understood that the slot of the frame 4 can be adapted to the specifications of the temperature exchange device node 11, including length, height, and width, for a smooth installation. The installation method can be a push-pull slot installation, a direct-load-bearing slot installation, etc., and no special requirements are placed on the installation method.

[0057] Specifically, the frame is provided with a front door 12 and a rear door 13, providing a passage for the installation of the temperature exchange equipment node 11 and facilitating its maintenance. The front door 12 and rear door 13 should be closed when the temperature exchange unit is operating. Understandably, when the front door 12 and rear door 13 are closed, the gaps between the door frames should be properly sealed to prevent leakage.

[0058] The frame 4 is also provided with a frame liquid inlet 3 and a frame lower end liquid return port 2. The frame liquid inlet 3 is a channel for the main liquid inlet pipe 7 to enter the frame 4, and the position of the frame liquid inlet 3 is not specially required. Preferably, the frame liquid inlet 3 can be designed near one side of the frame front door 12 or the frame rear door 13, which is convenient for connection with the main liquid return pipe; the frame lower end liquid return port 2 needs to be arranged at the bottom of the frame 4, so that the temperature exchange medium collected at the bottom of the frame can smoothly flow out of the frame and enter the liquid return pipe 15; preferably, the frame lower end liquid return port 2 can also be designed near one side of the frame front door 12 or the frame rear door 13, which is convenient for connection with the liquid return pipe.

[0059] Specifically, the temperature exchange medium circulation system includes a main liquid inlet pipe 7, a sub-liquid inlet pipe 8, a liquid return pipe 15, a medium driving device 6 and a liquid storage container 5, wherein one temperature exchange equipment node 11 corresponds to one or more sub-liquid inlet pipes 8. The node liquid inlet port 9 is connected to one end of the corresponding sub-liquid inlet pipe 8, and the other end of each sub-liquid inlet pipe 8 is connected to one end of the main liquid inlet pipe 7 through the frame liquid inlet 3.

[0060] Specifically, the temperature exchange equipment node 11 is provided with one or more node liquid inlet ports 9 and node liquid return ports 10. Understandably, the temperature exchange equipment node 11 can use different temperature exchange methods for temperature exchange, and the number and position of the node liquid inlet ports 9 and the node liquid return ports 10 required by different temperature exchange methods will change accordingly, so one temperature exchange equipment node 11 needs to correspond to one or more node liquid inlet ports 9 and node liquid return ports 10 according to different temperature exchange methods; it can be understood that, because one temperature exchange equipment node 11 corresponds to one or more node liquid inlet ports 9, the multi-way input of the temperature exchange medium is realized, so the number of sub-liquid inlet pipes 8 needs to correspond to the number of node liquid inlet ports 9, and the corresponding sub-liquid inlet pipes 8 and node liquid inlet ports 9 are connected one by one.

[0061] Understandably, the other end of each sub-liquid inlet pipe 8 is connected to one end of the main liquid inlet pipe 7 through the frame liquid inlet 3, so that the temperature exchange medium is divided into each sub-liquid inlet pipe 8 through the main liquid inlet pipe 7, thereby entering each temperature exchange equipment node 11.

[0062] Specifically, the medium driving device 6 and the liquid storage container 5 are arranged outside the frame 4; one end of the liquid return pipe 15 is connected to the frame lower end liquid return port 2, the other end of the liquid return pipe 15 is connected to the liquid storage container 5, and the liquid storage container 5 is also connected to the main liquid inlet pipe 7. Understandably, the liquid storage container 5 is also connected to the liquid inlet pipe 7 (not shown in the figure), thereby forming a closed loop for the circulation of the temperature exchange medium outside the frame 4. After the temperature exchange medium is recovered in the liquid storage container 5, the temperature exchange medium is treated and then transported from the main liquid inlet pipe 7 to the temperature exchange equipment node 11 again.

[0063] It can be understood that the medium driving device 6 is arranged on the main liquid inlet pipe 7 or the liquid return pipe 15, so as to provide power for the temperature exchange medium and complete the circulation of the temperature exchange medium in the temperature exchange unit. It can be understood that the pipeline of the temperature exchange unit includes the main liquid inlet pipe 7 and the liquid return pipe 15, and the liquid port of the temperature exchange unit includes the frame body liquid inlet port 3, the frame body top liquid return port 1 and the frame body lower end liquid return port 2. Preferably, the pipeline and the liquid port of the temperature exchange unit can be arranged on one side of the frame body front door 12 or the frame body rear door 13. Correspondingly, the node liquid port of the temperature exchange device node includes the node liquid inlet port 9 and the node liquid return port 10, and the liquid port of the temperature exchange device node should also be designed on the side close to the frame body front door or the frame body rear door, so that each frame body liquid port, each temperature exchange device node liquid port and each frame body pipeline are conveniently connected, so that the layout is clear and maintenance is convenient.

[0064] Specifically, the temperature exchange medium flows from the liquid storage container 5 into the main liquid inlet pipe 7, is branched from the main liquid inlet pipe 7 into each of the branch liquid inlet pipes 8, and enters the corresponding temperature exchange device node 11 through each of the branch liquid inlet pipes 8 to perform temperature exchange. The temperature exchange medium that has completed the temperature exchange work flows out of the node liquid return port 10 of the temperature exchange device node 11 and is collected at the bottom of the frame body 4, and finally enters the liquid return pipe 15 through the frame body lower end liquid return port 2 and flows into the liquid storage container 5 through the liquid return pipe 15.

[0065] Compared with the pipeline scheme of the conventional temperature exchange medium circulation, the utility model reduces the use amount of the liquid return pipe 15, can save the cost of pipeline materials, and prevents the complex pipeline layout. Furthermore, the temperature exchange medium directly flows out of the node liquid return port 10 of the temperature exchange device node 11 and is collected at the bottom of the frame body 4, so that the temperature exchange medium is recovered, the pressure of the liquid return pipeline is reduced, the temperature exchange unit is prevented from being unable to work due to excessive pipe pressure of the liquid return pipe 15, and the efficiency of the temperature exchange work is improved.

[0066] Optionally, the temperature exchange device node 11 includes a node shell 51 and one or more temperature exchange devices arranged in the node shell 51, and the one or more temperature exchange devices realize one or more temperature exchange modes of spray temperature exchange, immersion temperature exchange and cold plate temperature exchange based on the temperature exchange medium input by the branch liquid inlet pipe 8.

[0067] Optionally, when the one or more temperature exchange devices realize the spray temperature exchange mode based on the temperature exchange medium input by the branch liquid inlet pipe 8, the node liquid return port 10 is arranged at the lower end of the node shell 51. Figure 2 A temperature exchange device node for realizing spray temperature exchange is provided.

[0068] Exemplarily, the temperature exchange devices include secondary temperature exchange devices 57 and primary temperature exchange devices 58; the PCB board 54 is a basic component for supporting and connecting the temperature exchange devices, which provides a mechanical base for the temperature exchange devices and realizes the electrical connection between the devices through a series of conductive paths (usually copper foil).

[0069] Specifically, Figure 2 The secondary temperature exchange devices 57 and the primary temperature exchange devices 58 exchange heat with the temperature exchange medium sprayed by the first spraying device 53 located at the top of the node shell 51. The temperature exchange medium enters the first spraying device 53 of the temperature exchange device node 11 through the node inlet 9 through the branch inlet pipe 8. It can be understood that the first spraying device 53 is provided with a spraying cavity, and the lower surface of the spraying cavity is provided with a plurality of spraying holes, so that the temperature exchange medium can be sprayed downward.

[0070] It can be understood that the diameter of the liquid inlet of the first spraying device 53 is much larger than the diameter of the spraying hole, so that the flow rate of the temperature exchange medium flowing into the first spraying device is much larger than the spraying speed of the temperature exchange medium, so that the temperature exchange medium can quickly fill the spraying cavity, and the temperature exchange medium sprayed downward is powered. The temperature exchange medium sprayed downward exchanges heat after contacting the secondary temperature exchange devices 57 and the primary temperature exchange devices 58, and then flows out at the node return liquid outlet 10.

[0071] The node return liquid outlet 10 is arranged at the lower end of the node shell 51, so that the temperature exchange medium collected at the bottom of the temperature exchange device node 11 can smoothly flow out from the node return liquid outlet 10.

[0072] Optionally, when one or more of the temperature exchange devices realize immersion temperature exchange based on the temperature exchange medium input by the branch inlet pipe 8, the node return liquid outlet 10 is arranged at the middle position of the node shell 51, and the middle position is higher than the upper surface of the temperature exchange device. For example, Figure 3 A schematic diagram of the temperature exchange device node for realizing immersion temperature exchange is provided.

[0073] Exemplarily, Figure 3 The secondary temperature exchange devices 57 and the primary temperature exchange devices 58 exchange heat by immersion in the temperature exchange medium. The temperature exchange medium enters the temperature exchange device node through the node inlet 9 through the branch inlet pipe 8; the node return liquid outlet 10 is arranged at the middle position of the node shell 51, and the middle position is higher than the upper surface of the secondary temperature exchange devices 57 and the primary temperature exchange devices 58, so that the temperature exchange medium can be collected at the bottom of the temperature exchange device node before flowing out at the node return liquid outlet 10, and the liquid height of the temperature exchange medium is higher than that of the secondary temperature exchange devices 57 and the primary temperature exchange devices 58, so that the secondary temperature exchange devices 57 and the primary temperature exchange devices 58 are immersed in the temperature exchange medium.

[0074] Optionally, when one or more of the temperature exchange devices achieve cold plate temperature exchange mode based on the temperature exchange medium input by the distribution liquid pipe 8, the temperature exchange medium exchanges temperature with the temperature exchange devices through the distribution liquid pipe 8. The two schemes include the following two schemes.

[0075] One is that the distribution liquid pipe 8 is arranged in a disc return mode on the upper surface of the temperature exchange device, and the pipe wall of the disc return type distribution liquid pipe 8 is closely attached to the temperature exchange device, so that the contact area of the distribution liquid pipe 8 and the temperature exchange device is increased, thereby fully exchanging heat with the temperature exchange device; the other end of the distribution liquid pipe 8 is connected with the node return liquid port 10, and the temperature exchanged temperature exchange medium flows out of the node shell 51 from the node return liquid port 10 through the distribution liquid pipe 8;

[0076] Two is that the temperature exchange medium enters the cold plate through the distribution liquid pipe 8, the cold plate is internally provided with a cold plate cavity, and the cold plate cavity is provided with a cold plate liquid inlet and a cold plate liquid outlet; the temperature exchange medium enters the cold plate cavity through the cold plate liquid inlet, and after completing the temperature exchange work, the temperature exchange medium is discharged through the cold plate liquid outlet.

[0077] The temperature exchange medium is discharged in two ways: one is that the cold plate liquid outlet is externally connected with a return liquid pipe, and the temperature exchange medium flows out of the node shell 51 through the return liquid pipe; the other is that the cold plate liquid outlet is not connected with the return liquid pipe, and the temperature exchange medium directly flows into the node shell 51 and flows out of the node shell 51 through the return liquid port of the temperature exchange device node.

[0078] Optionally, when one or more of the temperature exchange devices achieve spray temperature exchange and immersion temperature exchange mode based on the temperature exchange medium input by the distribution liquid pipe, the node return liquid port 10 is arranged at a middle position of the node shell 51, and the middle position is higher than the upper surface of the temperature exchange device. Figure 4 , a temperature exchange device node schematic diagram for realizing spray and immersion temperature exchange is provided.

[0079] Specifically, Figure 4 The secondary heat exchange device 57 and the primary heat exchange device 58 can exchange heat with the temperature exchange medium sprayed by the first spray device 53 located at the top of the node shell 51, and can also exchange heat by being immersed in the temperature exchange medium. The first spray device 53 enters the first spray device 53 through the distribution liquid pipe 8; it can be understood that the first spray device 53 is provided with a spray cavity, and a plurality of spray holes are arranged on the lower surface of the spray cavity corresponding to the secondary heat exchange device 57 and the primary heat exchange device 58, so that the temperature exchange medium can be sprayed downward; the flow rate between the first spray device 53 is designed and the same as the above-mentioned introduction of realizing spray temperature exchange, and will not be repeated here. The temperature exchange medium sprayed downward exchanges heat with the temperature exchange device and is collected at the bottom of the temperature exchange device node 11;

[0080] The node return liquid port 10 is arranged at the middle position of the node shell 51, and the middle position is higher than the upper surfaces of the secondary heat exchange device 57 and the primary heat exchange device 58, so that the temperature exchange medium can accumulate to a liquid level higher than the secondary heat exchange device 57 and the primary heat exchange device 58 at the bottom of the node of the temperature exchange device before flowing out of the node return liquid port 10, and the secondary heat exchange device 57 and the primary heat exchange device 58 are immersed for temperature exchange.

[0081] Optionally, when one or more of the temperature exchange devices realize spray temperature exchange and cold plate temperature exchange based on the temperature exchange medium input by the distribution liquid pipe, the node return liquid port 10 is arranged at the lower end of the node shell 51; the temperature exchange medium exchanges temperature with the temperature exchange device through the distribution liquid pipe 8, and the other end of the distribution liquid pipe 8 is connected with the node return liquid port 10, and the temperature exchanged temperature exchange medium flows out of the node shell 51 from the node return liquid port 10 through the distribution liquid pipe 8; or the temperature exchange device comprises a cold plate attached to the temperature exchange device, the temperature exchange medium enters the cold plate through the distribution liquid pipe 8 to exchange temperature with the temperature exchange device, and the temperature exchanged temperature exchange medium flows out of the cold plate and then enters the node shell 51. Figure 5 , a temperature exchange device node schematic diagram for realizing spray and cold plate temperature exchange is provided.

[0082] Specifically, Figure 5 The secondary heat exchange device 57 exchanges heat with the temperature exchange medium sprayed by the first spray device 53 arranged at the top of the node shell 51, and the primary heat exchange device 58 exchanges heat by the cold plate temperature exchange mode. It can be understood that the cold plate temperature exchange of the primary heat exchange device 58 is the same as the introduction of the above two cold plate temperature exchange schemes, and will not be repeated here. In terms of spraying, the temperature exchange medium enters the first spray device 53 through the distribution liquid pipe 8; it can be understood that the first spray device 53 is provided with a spray cavity, and a plurality of spray holes are arranged on the lower surface of the spray cavity corresponding to the secondary heat exchange device 57, which can realize downward spraying of the temperature exchange medium; the flow rate design between the first spray device 53 is the same as the introduction of the above-mentioned spray temperature exchange mode, and will not be repeated here. The temperature exchange medium sprayed downward exchanges heat after contacting the secondary heat exchange device 57, and finally flows out of the node return liquid port 10 of the node of the temperature exchange device 11. The node return liquid port 10 is arranged at the lower end of the node shell 51, so that the temperature exchange medium collected at the bottom of the node of the temperature exchange device 11 can flow out of the node return liquid port 10 smoothly. In the specific implementation process, the secondary heat exchange device 57 can also exchange temperature by the cold plate temperature exchange mode, and the primary heat exchange device 58 can also exchange temperature by the spray temperature exchange mode, and the specific implementation mode will not be repeated.

[0083] Optionally, when one or more of the temperature exchange devices achieve immersion temperature exchange and cold plate temperature exchange based on the temperature exchange medium input by the distribution liquid pipe 8, the node return liquid port 10 is arranged at a middle position of the node shell 51, and the middle position is higher than the upper surface of the temperature exchange device; the temperature exchange medium exchanges temperature with the temperature exchange device through the distribution liquid pipe 8, and the other end of the distribution liquid pipe 8 is connected with the node return liquid port 10, and the temperature exchanged temperature exchange medium flows out of the node shell 51 from the node return liquid port 10 through the distribution liquid pipe 8; or it includes a cold plate attached to the temperature exchange device, the temperature exchange medium enters the cold plate through the distribution liquid pipe 8, exchanges temperature with the temperature exchange device, and after the temperature exchanged temperature exchange medium flows out of the cold plate, it enters the node shell 51. It can be understood that the cold plate temperature exchange adopted by the temperature exchange device is the same as the introduction of the above two schemes for realizing cold plate temperature exchange, and will not be repeated here. For example Figure 6 , a temperature exchange device node schematic diagram for realizing immersion and cold plate temperature exchange is provided.

[0084] Exemplarily, Figure 6 The main heat exchange device 58 and the lower surface of the cold plate 59 are in full contact for heat exchange, and the temperature exchange medium completing temperature exchange in the cold plate 59 flows out of the inside of the temperature exchange device node 11 through the cold plate return liquid port 63 and collects at the bottom thereof. When the temperature exchange medium collected at the bottom of the temperature exchange device node 11 is sufficient, the liquid level of the temperature exchange medium is higher than the height of the temperature exchange device, so that the secondary temperature exchange device 57 and the main heat exchange device 58 realize heat exchange in immersion, and finally flow out through the node return liquid port 10. It can be understood that the node return liquid port 10 is arranged at a middle position of the node shell 51, and the middle position is higher than the upper surface of the temperature exchange device, so as to ensure that the liquid level of the collected temperature exchange medium is higher than the height of the temperature exchange device, so as to achieve the immersion effect. In the specific implementation process, the secondary temperature exchange device 57 can also be temperature exchanged by the cold plate temperature exchange mode, and the specific implementation mode will not be repeated.

[0085] Optionally, when one or more of the temperature exchange devices achieve the spray temperature exchange, the immersion temperature exchange and the cold plate temperature exchange mode based on the temperature exchange medium input by the branch liquid inlet pipe 8, the node liquid return port 10 is arranged at the middle position of the node shell 51, and the middle position is higher than the upper surface of the temperature exchange device; the temperature exchange medium exchanges heat with the temperature exchange device through the branch liquid inlet pipe 8, and the other end of the branch liquid inlet pipe 8 is connected with the node liquid return port 10; the temperature exchanged temperature exchange medium flows out of the node shell 51 through the branch liquid inlet pipe 8 from the node liquid return port 10; or it includes a cold plate attached to the temperature exchange device, the temperature exchange medium enters the cold plate through the branch liquid inlet pipe 8, exchanges heat with the temperature exchange device, and the temperature exchanged temperature exchange medium flows out of the cold plate and enters the node shell 51. It can be understood that the two schemes for realizing the cold plate temperature exchange and the introduction of the two schemes for realizing the cold plate temperature exchange are the same, and will not be repeated here. As Figure 7 A temperature exchange device node schematic diagram for realizing spray temperature exchange, immersion temperature exchange and cold plate temperature exchange is provided.

[0086] Specifically, Figure 7 The secondary temperature exchange device 57 can exchange heat with the temperature exchange medium sprayed by the first spray device 53 located at the top of the shell, and can also exchange heat by immersion in the temperature exchange medium; the main temperature exchange device 58 can exchange heat with the upper surface of the cold plate 55 and can also exchange heat by immersion in the temperature exchange medium. In the specific implementation process, the secondary temperature exchange device 57 can also simultaneously exchange heat by the cold plate temperature exchange mode, and the main temperature exchange device 58 can also simultaneously exchange heat by the spray temperature exchange mode, and the specific implementation mode will not be repeated here.

[0087] The spray temperature exchange is the same as the implementation mode described above, and will not be repeated here;

[0088] The immersion temperature exchange is the same as the implementation mode described above, and will not be repeated here;

[0089] The cold plate temperature exchange is the same as the implementation mode described above, and will not be repeated here.

[0090] Specifically, the spray temperature exchange mode is realized by the first spray device and / or the second spray device arranged inside the temperature exchange device node;

[0091] The implementation mode of the spray temperature exchange mode is:

[0092] The first spray device sprays all the temperature exchange devices in the temperature exchange device node in a one-to-many manner, and the first spray device is located at the top inside the temperature exchange device node; or,

[0093] The second spraying device is used to spray each of the temperature exchange devices in the temperature exchange equipment node on a one-to-one basis; or...

[0094] Simultaneously, the first spray device and the second spray device are used to spray the temperature exchange equipment. The first spray device is used to spray all the temperature exchange equipment in the temperature exchange equipment node in a one-to-many manner. The first spray device is located at the top inside the temperature exchange equipment node. The second spray device is used to spray one or more of the temperature exchange equipment in the temperature exchange equipment node in a one-to-one manner.

[0095] Preferably, the cross-section of the second spray device is a U-shaped structure, and the second spray device is provided with a medium chamber one and a medium chamber two. The medium chamber one and the medium chamber two are isolated by a card plate with a jet hole. The bottom of the second spray device is in contact with the surface of the temperature exchange equipment. The lower end of the second spray device is provided with a medium chamber two return port that communicates with the inside of the node of the temperature exchange equipment.

[0096] like Figure 10 The diagram shows the structure of a second spray device. This second spray device includes a first media chamber 64 and a second media chamber 65, which are separated by a retaining plate with a jet hole 61. The first media chamber 64 has a first media chamber inlet 62, which is connected to the branch inlet pipe 8. The second media chamber 65 has a second media chamber return port 63. Because the second spray device has a U-shaped structure, the second media chamber is an open structure without a bottom, allowing the sprayed temperature-changing medium to directly contact the temperature-changing equipment. After entering the first media chamber 64, the temperature-changing medium enters the second media chamber 65 through the jet hole 61 and then flows out through the second media chamber return port 63. Understandably, the diameter of the inlet 62 of the first medium chamber 64 is much larger than the diameter of the jet orifice 61, allowing the heat exchange medium to quickly fill the first medium chamber 64, applying pressure and providing power for the downward jetting heat exchange medium. Understandably, the pressure of the heat exchange medium can be controlled by the inlet speed of the heat exchange medium. The downward jetting heat exchange medium is directly sprayed onto the heat exchange device 58 through the second medium chamber 65, fully exchanging heat with the heat exchange device 58. Understandably, the vertical distance between the card plate and the heat exchange device 58 conforms to a preset height. Preferably, to improve the spraying effect, in this example, the preset height is set to 0.5-5mm.

[0097] It is understood that there are no special requirements on the number of the return ports 63 of the second medium cavity, and the positions of the return ports 63 of the second medium cavity can be set on the left and right lower ends of the second medium cavity 65.

[0098] It can be understood that the second spraying device can use the pressure of the temperature exchange medium to spray the temperature exchange equipment at a close distance, and the structure of the medium cavity two can make the temperature exchange medium concentrate on one temperature exchange equipment for temperature exchange, so as to achieve the effect of accurate temperature exchange of one temperature exchange equipment.

[0099] It can be understood that the first spraying device and the second spraying device can be used together to achieve the temperature exchange effect of the temperature exchange equipment.

[0100] As shown in the drawings, Figure 8 On the basis of the temperature exchange unit realized in the application, the utility model also provides a temperature exchange device, which comprises two or more temperature exchange units and a cabinet body for mounting the temperature exchange units, and the cabinet body is provided with cabinet through holes through which the main liquid inlet pipe and the liquid return pipe pass.

[0101] The temperature exchange units are provided with frame top liquid return ports 1, and the two or more temperature exchange units are connected from top to bottom in the cabinet body, and the temperature exchange medium returns in series.

[0102] The main liquid inlet pipe 7 enters the cabinet body through the cabinet through hole and then enters the frame 4 of each temperature exchange unit through the frame liquid inlet port 3 of each temperature exchange unit; the temperature exchange medium flows into the branch liquid inlet pipe 8 of each temperature exchange unit through the main liquid inlet pipe 7, so as to enter the inside of the temperature exchange equipment node 11 for temperature exchange.

[0103] The frame top liquid return port 1 of the temperature exchange unit located at the top of the cabinet body is in a closed state, the frame lower end liquid return port 2 of the temperature exchange unit located at the bottom of the cabinet body is connected to the liquid storage container 5 through the liquid return pipe 15, and the frame lower end liquid return port 2 of the other temperature exchange units in the cabinet body is connected to the top liquid return port 1 of the temperature exchange unit located below and adjacent to the other temperature exchange unit through the liquid return pipe 15, except for the frame top liquid return port 1 of the temperature exchange unit located at the top of the cabinet body and the frame lower end liquid return port 2 of the temperature exchange unit located at the bottom of the cabinet body.

[0104] For example, Figure 8 The cabinet body of the temperature exchange device is provided with a mounting structure for mounting the temperature exchange units, the mounting structure can be realized by a clamping groove, and the clamping groove of the cabinet body needs to be one-to-one corresponding to the attribute specifications of the temperature exchange units in design, so that the temperature exchange units can be fitted and mounted in the cabinet body. A plurality of temperature exchange units are mounted in the cabinet body, which can realize the use of a plurality of temperature exchange units in one temperature exchange device, improve the temperature exchange efficiency and the flexibility of the temperature exchange scheme.

[0105] Specifically, the cabinet body is provided with front and rear cabinet doors for facilitating installation of devices; the top of the cabinet body is provided with cable holes which are passages for cables of the temperature exchange units; the top and bottom of the cabinet body are provided with through holes which are pipeline passages for inlet and outlet liquid pipes; the cabinet body can be provided with an accessory installation area in the middle region between the two temperature exchange units for installation of other devices required for operation of the temperature exchange units, such as a control switch, a PBU power supply system and a wire arrangement rack, so as to ensure normal operation of the temperature exchange units. Other specifications of the cabinet body are not specially required.

[0106] Specifically, the bottom of the main inlet liquid pipe 7 is connected to the liquid storage container 5 and enters the cabinet body through the through hole of the cabinet body; the main inlet liquid pipe 7 enters the frame 4 of each temperature exchange unit through the inlet liquid port 3 of the frame of each temperature exchange unit and is connected to each branch inlet liquid pipe 8 which is connected to the inlet liquid port 3 of the frame of the temperature exchange device node 11 of the temperature exchange unit; the temperature exchange medium flows into each branch inlet liquid pipe 8 of each temperature exchange unit through the main inlet liquid pipe 7, thereby entering the inside of the temperature exchange device node 11 for temperature exchange (not shown in the figure);

[0107] Preferably, each temperature exchange unit is provided with two frame inlet liquid ports, so that the main inlet liquid pipe penetrates through the temperature exchange unit, that is, the main inlet liquid pipe 7 enters the inside of the temperature exchange unit located at the bottom of the frame from the frame inlet liquid port located at the bottom of the frame, extends out from the other frame inlet liquid port of the temperature exchange unit located at the bottom of the frame, continues to enter the inside of the temperature exchange unit located at the middle of the frame from the frame inlet liquid port located at the middle of the frame, extends out from the other frame inlet liquid port of the temperature exchange unit located at the middle of the frame, finally enters the inside of the temperature exchange unit located at the top of the frame from the frame inlet liquid port located at the top of the frame, and extends out from the other frame inlet liquid port of the temperature exchange unit located at the top of the frame to the top of the cabinet body, wherein the top of the main inlet liquid pipe 7 is sealed. The above-mentioned inlet liquid pipe connection scheme can shorten the distance between each branch inlet liquid pipe 8 and the main inlet liquid pipe 7, thereby reducing the length of each branch inlet liquid pipe 8; without the need for multiple main inlet liquid pipes 7 to input temperature exchange medium into each temperature exchange unit one by one, the use length of the main inlet liquid pipe 7 is also reduced, thereby achieving the purpose of reducing the use of pipelines.

[0108] In terms of backflow, Figure 8 The first temperature exchange unit is located at the top of the cabinet body, the second temperature exchange unit is located at the middle of the cabinet body, and the third temperature exchange unit is located at the bottom of the cabinet body;

[0109] The top backflow port 1 of the first temperature exchange unit is in a sealed state; the lower end backflow port 2 of the frame of the first temperature exchange unit is connected to the top backflow port 1 of the second temperature exchange unit through the backflow pipe 15, wherein the second temperature exchange unit is located below and adjacent to the first temperature exchange unit;

[0110] The top liquid return port 1 of the second temperature exchange unit is connected with the first temperature exchange unit through the liquid return pipe 15 of the first temperature exchange unit, and the lower end liquid return port 2 of the frame body of the first temperature exchange unit is connected with the top liquid return port 1 of the third temperature exchange unit through the liquid return pipe 15 of the first temperature exchange unit, wherein the first temperature exchange unit is located above and adjacent to the second temperature exchange unit, and the third temperature exchange unit is located below and adjacent to the second temperature exchange unit.

[0111] The lower end liquid return port 2 of the frame body of the third temperature exchange unit is connected with the liquid storage container 5 through the liquid return pipe 15, and the top liquid return port 1 of the third temperature exchange unit is connected with the lower end liquid return port 2 of the frame body of the second temperature exchange unit through the liquid return pipe 15 of the second temperature exchange unit, wherein the second temperature exchange unit is located above and adjacent to the third temperature exchange unit.

[0112] It can be understood that if the temperature exchange device needs to install more temperature exchange units, each temperature exchange unit can be installed according to the corresponding installation mode according to the position of the cabinet body, including the top, middle and top of the cabinet body.

[0113] It can be understood that the temperature exchange medium in the liquid storage container 5 enters each temperature exchange unit through the main liquid distribution pipe 7, and then enters the temperature exchange device node 11 through each liquid distribution pipe 8 to exchange the temperature of the temperature exchange device. The temperature exchange medium that has completed temperature exchange in the first temperature exchange unit flows out through the node liquid return port 10, and is collected at the bottom of the first temperature exchange unit due to gravity, and is drained into the second temperature exchange unit through the liquid return pipe 15 thereof, and is collected at the bottom of the second temperature exchange unit due to gravity. Similarly, the temperature exchange medium that has completed temperature exchange in the second temperature exchange unit flows out through the node liquid return port 10, and is collected at the bottom of the second temperature exchange unit due to gravity together with the temperature exchange medium flowing down from the first temperature exchange unit. In this way, when all the temperature exchange media are collected in the temperature exchange unit at the bottom of the frame body, they are returned to the liquid storage container 5 through the liquid return pipe 15 thereof, and the temperature exchange medium is recovered.

[0114] Exemplarily, the utility model also provides another installation mode of the temperature exchange unit in the temperature exchange device, that is, the installation mode of the two or more temperature exchange units in the cabinet body is from top to bottom or from left to right connection, and the temperature exchange medium returns in parallel:

[0115] It can be understood that the temperature exchange medium enters each temperature exchange device node 11 in the same way as described above, and the main liquid inlet pipe installation mode is the same as described above, which will not be repeated here.

[0116] The lower end liquid return port 2 of the frame body of each temperature exchange unit is connected with the liquid storage container 5 through the liquid return pipe 15, and the temperature exchange medium is recovered.

[0117] As Figure 9As shown, on the basis that the temperature exchange unit is installed in the temperature exchange device in the application, the temperature exchange unit and the temperature exchange device node 11 are also provided in the mixed installation mode of the temperature exchange device, that is, the cabinet of the temperature exchange device can be directly installed with the temperature exchange device node 11 in addition to the temperature exchange unit. It can be understood that the cabinet is internally provided with an installation structure, and the installation structure can be realized by a clamping groove; it can be understood that the clamping groove specifications for installing the temperature exchange device node 11 and the temperature exchange unit are different, because the temperature exchange unit can be internally installed with the temperature exchange device node 11, so the volume of the temperature exchange unit is larger than that of the temperature exchange device node 11. In order to flexibly design the installation positions of the temperature exchange device node 11 and the temperature exchange unit in the cabinet, related accessories should be provided to assemble with the clamping groove of the temperature exchange unit, so as to realize the conversion from the temperature exchange unit to the temperature exchange device node 11, so that each clamping groove of the cabinet can be installed with the temperature exchange device node 11 or the temperature exchange unit; it can be understood that because the space specifications of the cabinet are limited, the number of clamping grooves provided in the cabinet is limited, and the number of installed temperature exchange device nodes or the number of installed temperature exchange units is also limited.

[0118] Exemplarily, as Figure 9 A schematic diagram of mixed connection and installation of multiple temperature exchange units and temperature exchange device nodes in a temperature exchange device is provided in the application;

[0119] Specifically, the installation mode of the mixed installation of the multiple temperature exchange units and the multiple temperature exchange device nodes is from top to bottom connection, and the temperature exchange medium is returned in a series connection mode:

[0120] In terms of liquid inlet, the bottom of the main liquid inlet pipe 7 is connected with the liquid storage container 5, and enters the cabinet through the cabinet through hole; the main liquid inlet pipe 7 enters the frame 4 of each temperature exchange unit through the liquid inlet port 3 of each temperature exchange unit, is connected with each branch liquid inlet pipe 8, the branch liquid inlet pipe 8 is connected with the node liquid inlet port 9 of the temperature exchange device node installed in the temperature exchange unit; or, is directly connected with the branch liquid inlet pipe 8, and the branch liquid inlet pipe 8 is directly connected with the node liquid inlet port 9 of the temperature exchange device node 11 installed in the cabinet;

[0121] The temperature exchange medium flows into each branch liquid inlet pipe 8 of each temperature exchange unit through the main liquid inlet pipe 7, or flows into the branch liquid inlet pipe 8 (not shown in the figure) of each temperature exchange device node 11 installed in the cabinet;

[0122] The preferred liquid inlet scheme only needs to be adjusted on the installation of each temperature exchange unit, and the adjustment scheme is the same as the main liquid inlet pipe connection mode described above in the temperature exchange unit, which will not be described here.

[0123] In terms of liquid return, the scheme also includes a branch liquid return pipe 16 connected with the node liquid return port of each temperature exchange device node;

[0124] Specifically, if one or more temperature exchange device nodes 11 are installed at the top of the cabinet, a temperature exchange device node cluster is formed. The node inlet 9 of each temperature exchange device node 11 is connected to the branch inlet pipe 8, and the node outlet 10 of each temperature exchange device node is connected to the branch outlet pipe 16, the other end of each branch outlet pipe 16 being connected to the outlet pipe 15. The temperature exchange medium that has completed the temperature exchange work is collected in the outlet pipe 15 through the branch outlet pipes 16.

[0125] If another temperature exchange device node 11 is installed at the lower adjacent position of the last temperature exchange device node 11 of the temperature exchange device node cluster, the installation scheme is the node-node scheme, which is that the branch outlet pipe 16 of the lower temperature exchange device node 11 is continuously connected to the outlet pipe 15 in the same way as the temperature exchange device node cluster installed above, which will not be described here again.

[0126] If a temperature exchange unit is installed at the lower adjacent position of the last temperature exchange device node 11 of the temperature exchange device node cluster instead of another temperature exchange device node 11, the installation scheme is the node-unit scheme, which is that the outlet pipe 15 is connected to the top outlet port 1 of the temperature exchange unit, so that the temperature exchange medium collected in the outlet pipe 15 flows into the temperature exchange unit through the top outlet port 1 of the temperature exchange unit.

[0127] If one or more temperature exchange device nodes 11 are installed at the middle of the cabinet, a temperature exchange device node cluster is formed. The connection mode is the same as that of the temperature exchange device node cluster installed above, which will not be described here again.

[0128] If another temperature exchange device node 11 is installed at the upper adjacent position of the first temperature exchange device node of the temperature exchange device node cluster or at the lower adjacent position of the last temperature exchange device node of the temperature exchange device node cluster, the node-node scheme can be used for connection.

[0129] If a temperature exchange unit is installed at the upper adjacent position of the first temperature exchange device node 11 of the temperature exchange device node cluster, the installation scheme is the unit-node scheme, which is that the outlet pipe 15 is connected to the lower end outlet port 2 of the frame of the temperature exchange unit, so that the temperature exchange medium collected at the bottom of the temperature exchange unit flows into the outlet pipe 15 as the intermediate channel for returning to the storage container 5.

[0130] If a temperature exchange unit is installed at the lower adjacent position of the last temperature exchange device node 11 of the temperature exchange device node cluster, the node-unit scheme can be used for connection.

[0131] If one or more temperature exchange device nodes 11 are installed at the bottom of the cabinet, a temperature exchange device node cluster is formed. The connection mode is the same as the above-mentioned installation of the temperature exchange device node cluster, which will not be described here; and if no other temperature exchange unit or temperature exchange device node 11 is installed adjacent to the lower part of the last temperature exchange device node 11 of the temperature exchange device cluster, the liquid return pipe 15 is connected to the liquid storage container 5 to complete the recovery of the temperature exchange medium;

[0132] If a temperature exchange unit is installed adjacent to the upper part of the first temperature exchange device node 11 of the temperature exchange device node cluster, the unit-node scheme can be used for connection;

[0133] If a temperature exchange device node is installed adjacent to the upper part of the first temperature exchange device node 11 of the temperature exchange device node cluster, the node-node scheme can be used for connection.

[0134] Exemplarily, the utility model also provides another mixed installation mode of temperature exchange unit and temperature exchange device node in the temperature exchange device, that is, a plurality of temperature exchange units and a plurality of temperature exchange device nodes 11 are connected from top to bottom or from left to right, and the temperature exchange medium returns in parallel:

[0135] It can be understood that the temperature exchange medium enters each temperature exchange device node 11 or temperature exchange unit in the same way as the above-mentioned installation of the main liquid inlet pipe, which will not be described here;

[0136] Specifically, the liquid return port 2 at the lower end of the frame of each temperature exchange unit is connected to the liquid storage container 5 through the liquid return pipe 15, and the node liquid return port 10 of each temperature exchange device node 11 is connected to the liquid storage container 5 through the liquid return pipe 15, to complete the recovery of the temperature exchange medium.

[0137] Exemplarily, the utility model also provides a temperature exchange device node for realizing air cooling and cold plate temperature exchange, such as Figure 11 The temperature exchange device node for realizing air cooling and cold plate temperature exchange of the utility model is shown in the figure.

[0138] Specifically, the temperature exchange device node for realizing this temperature exchange mode can only be directly installed in the cabinet. It can be understood that the front door of the cabinet, the rear door of the cabinet, and the front door of the cabinet corresponding to the temperature exchange device node and the rear door of the cabinet should be provided with ventilation holes on both sides, and the ventilation holes can be adaptively opened and closed to meet the installation scene of the air cooling temperature exchange mode; when realizing air cooling temperature exchange, the ventilation holes of the cabinet front door and the cabinet rear door need to be opened to form ventilation.

[0139] Figure 11The middle secondary temperature exchange device 57 exchanges heat with air in the wind, and the main temperature exchange device 58 can exchange heat with the cold plate and air in the wind; it can be understood that the cold plate temperature exchange scheme is the same as the above-mentioned cold plate temperature exchange, which will not be repeated here. When the air-cooled temperature exchange mode is implemented, one side of the cabinet body is set as an air inlet area, and the other side of the cabinet body is set as an air outlet area; for example, Figure 11 The front door of the cabinet body is set as an air inlet area, and the other side of the rear door of the cabinet body is set as an air outlet area; air is blown at the front door of the cabinet body, so that air enters the temperature exchange device node, and is discharged from the rear door of the cabinet body after exchanging heat with the secondary temperature exchange device 57 and the main temperature exchange device 58.
