Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of electronic equipment, and in particular to a cabinet door and electronic equipment. BACKGROUND

[0002] Electronic equipment is a device that installs multiple numbers and types of heat generating devices in the same cabinet, and these heat generating devices can be cooperatively operated to perform large computation projects. Among them, the heat generating devices in the cabinet include a mainboard and electronic components arranged on the mainboard. For the main heat source such as CPU (Central Processing Unit), the cooling plate arranged thereon is often used for cooling, and for the remaining heat source such as memory, network card, etc., air cooling is often used, which will cause at least part of the hot air to blow out from the air outlet of the heat generating device.

[0003] At present, with the vigorous development of the data industry, the number of electronic equipment deployed in the machine room gradually develops from low density to high density, which makes the heat in the machine room larger and larger. In order to reduce the temperature of the machine room, condensers, heat exchangers and other devices are often arranged in the cabinet to reduce the temperature of the air outlet of the heat generating device, thereby reducing the air temperature of the data center.

[0004] However, the outer wall surface of the pipe body of the heat exchanger often accumulates a large amount of water droplets, which will be blown out with the air and wet the nearby personnel. SUMMARY

[0005] Embodiments of the present application provide a cabinet door and electronic equipment to solve the problem that the outer wall surface of the pipe body of the condenser in the liquid cooling door often accumulates a large amount of water droplets, which will be blown out with the air and wet the nearby personnel.

[0006] To achieve the above object, the present application provides the following technical solutions:

[0007] One aspect of the embodiments of the present application provides a cabinet door, comprising: a door body provided with a first flow outlet, the first flow outlet penetrating through the door body along a first direction, the door body being provided with a first side and a second side oppositely arranged along the first direction; a heat exchanger arranged on the first side of the door body, the heat exchanger comprising at least two heat exchange modules; each of the heat exchange modules comprises a liquid inlet main pipe, a liquid outlet main pipe and at least one heat exchange pipe, the liquid inlet main pipe comprising a first end and a second end oppositely arranged, the liquid outlet main pipe comprising a third end and a fourth end oppositely arranged; in each of the heat exchange modules, the inlet end of each of the heat exchange pipes is in communication with the liquid inlet main pipe, the outlet end of each of the heat exchange pipes is in communication with the liquid outlet main pipe, the first end of the liquid inlet main pipe is located above the second end, the inlet end of at least one of the heat exchange pipes is located between the first end and the second end, the third end of the liquid outlet main pipe is located above the fourth end, the outlet end of at least one of the heat exchange pipes is located between the third end and the fourth end; a liquid blocking cover arranged on the second side of the door body, the liquid blocking cover covering the first flow outlet and forming a channel between the liquid blocking cover and the door body, the channel being used for guiding the fluid passing through the first flow outlet to flow out.

[0008] The cabinet door provided by the present application can reduce the maintenance cost of the cabinet door with the heat exchanger by arranging the door body, arranging the heat exchanger on the first side of the door body along the first direction, arranging the heat exchanger comprising a plurality of split heat exchange modules, arranging each heat exchange module of the heat exchanger to have a smaller size, and arranging the heat exchange pipe of each heat exchange module to have a shorter length. When a fault occurs in the heat exchange module of the heat exchanger, only the heat exchange module with the fault or only the heat exchange pipe of the heat exchange module with the fault can be replaced, thereby reducing the maintenance cost of the cabinet door with the heat exchanger. In addition, when a certain heat exchange module needs to be repaired due to a fault, the entire heat exchanger does not need to be disassembled on the door body, only the heat exchange module with the fault needs to be disassembled on the door body, which is relatively easy to disassemble and relatively easy to maintain the heat exchanger. In addition, the length of the heat exchange pipe is shortened, which can reduce the processing difficulty of the heat exchange pipe, reduce the manufacturing cost of the heat exchanger, and be conducive to reducing the maintenance cost of the heat exchanger. Furthermore, the gas in the heat exchange pipe, whose inlet end is located between the first end and the second end of the liquid inlet main pipe and whose outlet end is located between the third end and the fourth end of the liquid outlet main pipe, can be easily discharged from the first end of the liquid inlet main pipe and the third end of the liquid outlet main pipe, thereby reducing the risk of air stagnation at the upper part of the middle of the heat exchange pipe, which makes it difficult for the refrigerant to enter.

[0009] In addition, by arranging the liquid blocking cover on the second side of the door body, the liquid blocking cover can be arranged on the first flow outlet and a channel is formed between the liquid blocking cover and the door body. The fluid can flow through the heat exchanger and the first flow outlet in sequence and flow out of the channel. The liquid blocking cover can block at least part of the fluid from flowing in the first direction and guide the fluid to flow out of the channel, so as to change the flow direction of the fluid and avoid the fluid from directly blowing on the nearby personnel. In addition, since the gas part and the liquid part in the fluid blown out of the first flow outlet have different densities, when the fluid blows on the liquid blocking cover, the gas part in the fluid is bent, and the liquid part in the fluid hits the liquid blocking cover due to inertia. In this way, the liquid part and the gas part in the fluid are separated, and the water content in the fluid blown out of the second flow outlet is reduced.

[0010] In one possible implementation, in the second direction, a projection of the liquid blocking cover on the surface of the door body is longer than the first flow outlet; and the second direction is perpendicular to the first direction.

[0011] By the above scheme, the liquid blocking cover can cover the first flow outlet in the second direction, so as to block the fluid from flowing in the first direction by the liquid blocking cover and guide the fluid to flow out of the channel, so as to further avoid the fluid from directly blowing on the nearby personnel.

[0012] In one possible implementation, the liquid blocking cover has a top end and a bottom end arranged oppositely in the second direction, the top end of the liquid blocking cover is connected to the door body, and the bottom end of the liquid blocking cover is beyond the bottom end of the first flow outlet and forms the channel between the liquid blocking cover and the door body.

[0013] By the above scheme, part of the fluid flows out of the top of the first flow outlet, and the gas part and the liquid part in the part of the fluid are separated by the different densities.

[0014] In one possible implementation, the bottom end of the liquid blocking cover is provided with a third flow outlet penetrating through the liquid blocking cover, and a top end surface of the third flow outlet is lower than a bottom end surface of the first flow outlet.

[0015] By the above scheme, the outflow amount of the fluid is increased.

[0016] In one possible implementation, the bottom end surface of the third flow outlet is flush with the bottom end surface of the liquid blocking cover.

[0017] By the above scheme, the separated liquid part is guided out.

[0018] In one possible implementation, the third flow outlet is a plurality of third flow outlets, and the plurality of third flow outlets are arranged at intervals in a third direction, and the third direction is perpendicular to a plane in which the first direction and the second direction are located.

[0019] The above scheme is adopted to facilitate the uniform outflow of the fluid in the third direction.

[0020] In one possible implementation, the liquid-blocking cover has a top end and a bottom end arranged oppositely in the second direction, the bottom end of the liquid-blocking cover is connected to the door body, and the top end of the liquid-blocking cover is beyond the top end of the first flow outlet and forms the passage with the door body.

[0021] The above scheme is adopted to make a part of the fluid flow out from below the first flow outlet and separate the gas part and the liquid part in the part of the fluid by the difference in density.

[0022] In one possible implementation, the bottom end of the liquid-blocking cover is provided with a fifth flow outlet penetrating through the liquid-blocking cover, and the top end surface of the fifth flow outlet is lower than the bottom end surface of the first flow outlet.

[0023] The above scheme is adopted to facilitate the increase of the outflow amount of the fluid.

[0024] In one possible implementation, the liquid-blocking cover has a top end and a bottom end arranged oppositely in the second direction, the bottom end of the liquid-blocking cover is beyond the bottom end of the first flow outlet and forms the passage with the door body, and the top end of the liquid-blocking cover is beyond the top end of the first flow outlet and forms the passage with the door body.

[0025] The above scheme is adopted to make a part of the fluid flow out from above the first flow outlet, separate the gas part and the liquid part in the part of the fluid by the difference in density, make another part of the fluid flow out from below the first flow outlet, and separate the gas part and the liquid part in the part of the fluid by the difference in density. The above scheme also facilitates the increase of the outflow amount of the fluid.

[0026] In one possible implementation, the liquid-blocking cover is connected to the door body at both ends in the second direction, and the surface of the liquid-blocking cover facing the door body forms the passage with the door body, the liquid-blocking cover is provided with a second flow outlet penetrating through the liquid-blocking cover, the second flow outlet is located on one side of the first flow outlet in the second direction, and the second flow outlet is in communication with the first flow outlet through the passage.

[0027] The above scheme is adopted to make the fluid flow out through the first flow outlet, the passage, and the second flow outlet. In the process of the fluid flowing from the first flow outlet to the second flow outlet, the gas part and the liquid part of the fluid are separated by the difference in density.

[0028] In one possible implementation, at least part of the liquid-blocking cover opposite to the first flow outlet has an inner arc wall, and the inner arc wall has an arc center facing the first flow outlet.

[0029] By the above scheme, the fluid is guided to flow out of the liquid baffle along the inner-arc wall, and the fluid flowing out of the liquid baffle can flow towards the outer surface of the door body.

[0030] In one possible implementation, the bottom end of the door body is provided with a water collecting tray, and the water collecting tray has an inner cavity and an opening, the opening is in communication with the inner cavity of the water collecting tray and faces the top end of the door body.

[0031] By the above scheme, the liquid part of the fluid flowing out of the liquid baffle is received.

[0032] One aspect of the embodiments of the present application provides an electronic device, which includes a heat generating device, a cabinet body, and a cabinet door as described above, the cabinet door and the cabinet body jointly define a containing space, the heat generating device is located in the containing space, and an air outlet of the heat generating device is in communication with the first flow outlet of the cabinet door, the heat exchanger of the cabinet door is arranged on a side of the door body of the cabinet door facing the heat generating device, and the liquid baffle of the cabinet door is arranged on a side of the door body of the cabinet door away from the heat generating device.

These drawings and written descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0069] The terms used in the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application, and the embodiments of the present application will be described in detail hereinafter with reference to the drawings.

[0070] Internet service providers, enterprise platforms, research institutions, etc. have a large amount of computing demand, and the job platform carrying storage, computing and network demand is called data center.

[0071] Figure 1 A schematic diagram of a data center is provided in an embodiment of the present application.

[0072] As shown in Figure 1 , the data center provided in an embodiment of the present application can include a machine room 100 and at least one electronic device 200 arranged in the machine room 100. It should be noted that the machine room 100 can be a closed room, or a room open on one side or multiple sides; can be a temporary room built, such as a tent room, a board room, etc., or a permanent room built.

[0073] It can be understood that the machine room 100 can only be provided with one electronic device 200, or can be provided with multiple electronic devices 200. When multiple electronic devices 200 are arranged in the machine room 100, each electronic device 200 can be the same, partially the same, or all different.

[0074] In an embodiment of the present application, the electronic device 200 can include but is not limited to a server, a storage, a communication cabinet, a power supply cabinet, etc. The electronic device 200 in the present embodiment is taken as a server for example.

[0075] Figure 2 A schematic diagram of an electronic device is provided in an embodiment of the present application.

[0076] As shown in Figure 2 , in an embodiment of the present application, the electronic device 200 can include a cabinet 300 and at least one heat generating device 400 mounted in the cabinet 300.

[0077] It can be understood that the cabinet 300 can only be mounted with one heat generating device 400, or can be mounted with multiple heat generating devices 400. When multiple heat generating devices 400 are mounted in the cabinet 300, each heat generating device 400 can be the same, partially the same, or all different.

[0078] In an embodiment of the present application, the heat generating device 400 can include but is not limited to a computing node, a storage node, a communication node, a power distribution node, etc., and the heat generating device 400 will generate heat in the cabinet 300 when working.

[0079] In an embodiment of the present application, the cabinet 300 can include a cabinet body 310, and the cabinet body 310 has a device mounting cavity 311. It can be understood that the heat generating device 400 of the electronic device 200 can be mounted in the device mounting cavity 311 of the cabinet body 310.

[0080] In an embodiment of the present application, a mounting structure for mounting the heat generating device 400 can be arranged on the cavity wall of the device mounting cavity 311, and the heat generating device 400 can be mounted in the device mounting cavity 311 through the mounting structure. For example, the mounting structure can be a buckle structure, a bolt, etc.

[0081] It can be understood that the heat generating device 400 in the device mounting cavity 311 can be horizontally arranged, vertically arranged or obliquely arranged.

[0082] It can be understood by those skilled in the art that the horizontal in the present application can not be an absolute horizontal, and a small deviation is allowed, for example, the included angle between the horizontal and the horizontal plane can be 1°, 3°, 5°, etc. The vertical in the present application can also not be an absolute vertical, and a small deviation is allowed, for example, the included angle between the vertical and the horizontal plane can be 85°, 87°, 89°, etc.

[0083] In the embodiment of the present application, at least one side of the cabinet 310 is provided with a taking and placing opening 312 communicated with the device mounting cavity 311, and a cabinet door 320 is arranged at the taking and placing opening 312. The cabinet door 320 is hingedly arranged on the cabinet 310 and can be used to cover the taking and placing opening 312 at the position thereof.

[0084] It can be understood that the cabinet 310 can be horizontally arranged, and the cabinet door 320 arranged on the cabinet 310 can be vertically arranged. The height direction of the cabinet door 320 can be a vertical direction, and the width direction and the thickness direction of the cabinet door 320 can be two horizontal directions respectively.

[0085] For example, one side edge of the cabinet door 320 can be hingedly connected with the cabinet 310, and the other side edge of the cabinet door 320 can be provided with a lock catch structure. When the cabinet door 320 is covered on the cabinet 310, the lock catch structure is locked with the corresponding matching structure on the cabinet 310, so that the cabinet door 320 is fixed on the cabinet 310 and can be opened and closed.

[0086] For example, the opposite side edges of the cabinet door 320 can be detachably connected with the cabinet 310 by means of fasteners, buckle structures or the like.

[0087] It can be understood that the cabinet 310 can be provided with the taking and placing opening 312 only on one side. For example, the taking and placing opening 312 is arranged on the front side of the cabinet 310, and the cabinet door 320 is arranged at the taking and placing opening 312 on the front side of the cabinet 310. The cabinet 310 can be provided with the taking and placing opening 312 on opposite sides, for example, the taking and placing openings 312 are arranged on the front side and the rear side of the cabinet 310, and the cabinet doors 320 are arranged at the taking and placing openings 312 on the front side and the rear side of the cabinet 310.

[0088] In the embodiment of the present application, at least one cabinet door 320 is integrated with a heat exchanger 322. Specifically, the cabinet door 320 integrated with the heat exchanger 322 can include a door body 321 and the heat exchanger 322. The heat exchanger 322 is assembled on the side of the door body 321 facing the heat generating device 400, and the heat exchanger 322 is fastened to the door body 321. The heat exchanger 322 can be used to absorb heat in the air, so that the refrigerant flowing in the heat exchanger 322 can take away the heat in the cabinet body 310.

[0089] It can be understood that when the cabinet door 320 is vertically arranged, the door body 321 is vertically arranged.

[0090] The height of the cabinet door 320 can be greater than the width of the cabinet door 320, and the height of the corresponding door body 321 can be greater than the width of the door body 321.

[0091] When the cabinet door 320 includes the door body 321 and the heat exchanger 322, the door body 321 can be installed on the cabinet body 310 in an openable and closable manner. For example, one side edge of the door body 321 can be hinged to the cabinet body 310, and the other side edge of the door body 321 can be locked and fixed to the cabinet body 310 through a lock catch structure and a corresponding matching structure. Alternatively, the opposite two side edges of the door body 321 can be detachably connected to the cabinet body 310.

[0092] When the cabinet body 310 is provided with access openings 312 on opposite sides, and cabinet doors 320 are arranged at the access openings 312 on the opposite sides, the cabinet door 320 at the access opening 312 on one side of the cabinet body 310 can be integrated with a heat exchanger 322, or the cabinet doors 320 at the access openings 312 on the opposite sides of the cabinet body 310 can be integrated with heat exchangers 322.

[0093] In the related art, the heat exchanger integrated on the cabinet door is of a whole structure, and the heat exchanger and the heat exchange pipes of the heat exchanger extend from the lower end of the door body to the upper end of the door body. The length of the heat exchange pipes is relatively long, and the heat exchange pipes are usually vertically arranged. When a fault occurs, the whole heat exchanger or the whole heat exchange pipes with a relatively long length need to be replaced, and the maintenance cost of the cabinet door integrated with the heat exchanger is relatively high. In addition, when the heat exchanger needs to be repaired, the whole heat exchanger needs to be disassembled on the door body, and the disassembly is difficult, so the repair of the heat exchanger is difficult. In addition, the processing difficulty of the slender heat exchange pipes is relatively high due to the small diameter of the heat exchange pipes, which increases the manufacturing cost of the heat exchanger and further increases the cost of replacing the heat exchange pipes or the heat exchanger. Furthermore, the middle part of the vertically arranged heat exchange pipes can have multiple high points, and the middle part of the heat exchange pipes can easily retain gas, which makes it difficult for the refrigerant to enter.

[0094] For example, Figure 2As shown, based on this, the embodiment of the present application provides a cabinet door 320, which comprises a door body 321 and a heat exchanger 322. The heat exchanger 322 comprises at least two heat exchange modules 3221. Each heat exchange module 3221 is fastened to the door body 321. Each heat exchange module 3221 can be used to absorb heat in the air.

[0095] In this way, the heat exchanger 322 comprises a plurality of split heat exchange modules 3221. The size of each heat exchange module 3221 of the heat exchanger 322 is small. The length of the heat exchange pipe 600 (as shown below) of each heat exchange module 3221 is short. When a heat exchange module 3221 of the heat exchanger 322 fails, only the failed heat exchange module 3221 or only the heat exchange pipe 600 of the failed heat exchange module 3221 needs to be replaced, which can reduce the maintenance cost of the cabinet door 320 with the heat exchanger 322. In addition, when a certain heat exchange module 3221 fails and needs to be repaired, the entire heat exchanger 322 does not need to be disassembled on the door body 321. Only the failed heat exchange module 3221 needs to be disassembled on the door body 321. The disassembly is relatively easy, and the maintenance of the heat exchanger 322 is relatively easy. In addition, the length of the heat exchange pipe 600 is shortened, which can reduce the processing difficulty of the heat exchange pipe 600. The manufacturing cost of the heat exchanger 322 is relatively low, which is conducive to reducing the maintenance cost of the heat exchanger 322. Figure 5 It can be understood that the heat exchanger 322 can comprise two, three, four or more split heat exchange modules 3221. In other words, two, three, four or more heat exchange modules 3221 can be fastened in the door body 321 of the cabinet door 320.

[0096] It can be understood that the arrangement of the plurality of heat exchange modules 3221 fastened in the door body 321 can not be limited. For example, the plurality of heat exchange modules 3221 fastened in the door body 321 can be distributed in sequence along the vertical direction or the width direction of the cabinet door 320. For another example, the plurality of heat exchange modules 3221 fastened in the door body 321 can also be distributed in a matrix or a ring array.

[0097] It can be understood that the door body 321 can comprise a frame (not shown). The door body 321 can only have one mounting opening surrounded by the frame. All the heat exchange modules 3221 are assembled in the same mounting opening.

[0098] It can be understood that the door body 321 can comprise a frame (not shown). The door body 321 can only have one mounting opening surrounded by the frame. All the heat exchange modules 3221 are assembled in the same mounting opening.

[0099] Alternatively, the door body 321 can include a frame and a frame strip (not shown), the frame strip being fixedly connected with the frame, and the frame and the frame strip can separate a plurality of installation openings. The number of the installation openings can be the same as the number of the heat exchange modules 3221, and the installation openings correspond to the heat exchange modules 3221 one by one, and each heat exchange module 3221 is assembled in a corresponding installation opening. The number of the installation openings can also be less than the number of the heat exchange modules 3221, and at least one heat exchange module 3221 is assembled in each installation opening, and one or more installation openings are provided with a plurality of heat exchange modules 3221.

[0100] In some embodiments of the present application, at least two adjacent heat exchange modules 3221 can be arranged at intervals, and a wind blocking structure 327 is arranged between the two adjacent heat exchange modules 3221 arranged at intervals, and the wind blocking structure 327 is used to block the air flowing through the gap between the heat exchange modules 3221 on both sides of the cabinet door 320.

[0101] In this way, when the two adjacent heat exchange modules 3221 are arranged at intervals, more air flowing through the cabinet door 320 with the heat exchanger 322 can enter the heat exchange modules 3221 to exchange heat, which is beneficial to improve the heat dissipation efficiency of the electronic device 200.

[0102] It can be understood that the wind blocking structure 327 can be a wind blocking plate or foam arranged between the two adjacent heat exchange modules 3221. The wind blocking structure 327 can also be a frame strip on the door body 321 for separating the two adjacent installation openings.

[0135] In the embodiment of the present application, at least one heat exchange pipe 600 is arranged horizontally.

[0136] In this way, the heat exchange pipe 600 arranged horizontally occupies less vertical space of the heat exchange module 3221, which is beneficial to increase the arrangement area of the heat exchange pipe 600. In addition, the gas in the heat exchange pipe 600 arranged horizontally is easier to exhaust.

[0141] In the embodiment of the present application, the liquid inlet main pipe 710 of each heat exchange module 3221 is arranged vertically.

[0142] In this way, the liquid inlet main pipe 710 can occupy less space in the horizontal direction of the heat exchange module 3221, which is beneficial to increase the arrangement area of the heat exchange pipe 600.

[0143] In the embodiment of the present application, the liquid outlet main pipe 720 of each heat exchange module 3221 is arranged vertically.

[0144] In this way, the liquid outlet main pipe 720 can occupy less space in the horizontal direction of the heat exchange module 3221, which is beneficial to increase the arrangement area of the heat exchange pipe 600.

[0145] In the embodiment of the present application, the liquid inlet main pipes 710 of at least two heat exchange modules 3221 are connected in series, and the liquid outlet main pipes 720 of at least two heat exchange modules 3221 are connected in series. The first end 711 of the liquid inlet main pipe 710 and the third end 721 of the liquid outlet main pipe 720 of the uppermost heat exchange module 3221 of the at least two heat exchange modules 3221 are both provided with an exhaust valve 800. Specifically, at least two heat exchange modules 3221 distributed in sequence along the vertical direction are fastened in the door body 321, the first end 711 is communicated with the second end 712 adjacent to it above, so that the liquid inlet main pipes 710 of the at least two heat exchange modules 3221 distributed in sequence along the vertical direction in the door body 321 are connected in series, the third end 721 is communicated with the fourth end 722 adjacent to it above, so that the liquid outlet main pipes 720 of the at least two heat exchange modules 3221 distributed in sequence along the vertical direction in the door body 321 are connected in series, and the first end 711 and the third end 721 of the topmost heat exchange module 3221 among the at least two heat exchange modules 3221 distributed in sequence along the vertical direction in the door body 321 are both provided with an exhaust valve 800.

[0146] In this way, the gas in the heat exchange tubes 600 of at least two heat exchange modules 3221 connected in series with the liquid inlet main pipe 710 and the liquid outlet main pipe 720 can be discharged through the exhaust valve 800 set at the first end 711 and the fourth end 722 of the top heat exchange module 3221, and the number of exhaust valves 800 required to be set for exhaust is relatively small.

[0147] In the embodiment of the present application, the second end 712 of the bottommost heat exchange module 3221 of the at least two heat exchange modules 3221 connected in series with the liquid inlet main pipe 710 and the liquid outlet main pipe 720 is connected to the output end of the refrigerant cooling system 500, and the fourth end 722 is connected to the input end of the refrigerant cooling system 500.

[0148] It can be understood that the second end 712 of the heat exchange module 3221 located at the bottom in the door body 321 can serve as the refrigerant inlet end of the heat exchange module 3221, and the fourth end 722 of the heat exchange module 3221 located at the bottom in the door body 321 can serve as the refrigerant outlet end of the heat exchange module 3221.

[0149] In the embodiment where the refrigerant cooling system 500 comprises the cold energy distribution unit 510, the second end 712 of the lowermost heat exchange module 3221 in the door body 321 is in communication with the output end of the cold energy distribution unit 510, and the fourth end 722 of the lowermost heat exchange module 3221 in the door body 321 is in communication with the input end of the cold energy distribution unit 510.

[0150] In the embodiment, the at least two heat exchange modules 3221 comprise a first heat exchange module and a second heat exchange module, the first heat exchange module and the second heat exchange module are adjacently arranged, and the second heat exchange module is arranged above the first heat exchange module.

[0151] For example, the first end 711 of the first heat exchange module and the second end 712 of the second heat exchange module can be welded and fixed to communicate the first end 711 of the first heat exchange module and the second end 712 of the second heat exchange module.

[0152] The third end 721 of the first heat exchange module and the fourth end 722 of the second heat exchange module can be welded and fixed to communicate the third end 721 of the first heat exchange module and the fourth end 722 of the second heat exchange module.

[0153] For example, the first end 711 of the first heat exchange module and the second end 712 of the second heat exchange module can be communicated through the first connecting pipe 730, and the third end 721 of the first heat exchange module and the fourth end 722 of the second heat exchange module can be communicated through the second connecting pipe 740.

[0154] It can be understood that the first connecting pipe 730 can be a rigid pipe or a flexible pipe. The second connecting pipe 740 can be a rigid pipe or a flexible pipe.

[0155] In the embodiment where the wind blocking structure 327 is arranged between the two adjacent heat exchange modules 3221, the wind blocking structure 327 arranged between the two adjacent heat exchange modules 3221 is provided with a first through hole (not shown) for the first connecting pipe 730 to pass through and a second through hole (not shown) for the second connecting pipe 740 to pass through, the first connecting pipe 730 is arranged in the first through hole, and the second connecting pipe 740 is arranged in the second through hole.

[0157] In the embodiment, the first connecting pipe 730 is a flexible pipe.

[0158] In this way, the first end 711 of the first heat exchange module and the second end 712 of the second heat exchange module are easily connected.

[0159] In the embodiment of the present application, the second connecting tube 740 is a flexible tube.

[0160] In this way, the connection between the third end 721 of the first heat exchange module and the fourth end 722 of the second heat exchange module is easier.

[0161] Figure 6 A schematic diagram of the connection of multiple heat exchange modules of another electronic device provided in an embodiment of the present application.

[0162] like Figure 6 As shown, in the embodiment of the present application, the first end 711 of the liquid inlet main pipe 710 of the first heat exchange module and the second end 712 of the liquid inlet main pipe 710 of the second heat exchange module are staggered in the horizontal direction.

[0163] In this way, the interval between the first end 711 of the first heat exchange module and the second end 712 of the second heat exchange module is larger, and the first end 711 of the first heat exchange module and the second end 712 of the second heat exchange module are connected more easily.

[0164] It can be understood that when the first end 711 of the first heat exchange module and the second end 712 of the second heat exchange module are staggered in the horizontal direction, the projection of the first end 711 of the first heat exchange module along the vertical direction is staggered with the projection of the second end 712 of the second heat exchange module along the vertical direction.

[0165] The first end 711 of the first heat exchange module and the second end 712 of the second heat exchange module can be staggered in the thickness direction of the cabinet door 320. The first end 711 of the first heat exchange module and the second end 712 of the second heat exchange module can be staggered in the width direction of the cabinet door 320. The first end 711 of the first heat exchange module and the second end 712 of the second heat exchange module can also be staggered in both the thickness and width directions of the cabinet door 320.

[0166] The first end 711 of the liquid inlet main pipe 710 of the first heat exchange module and the second end 712 of the liquid inlet main pipe 710 of the second heat exchange module may be connected via a first connecting pipe 730 .

[0167] In the embodiment of the present application, the third end 721 of the liquid outlet main pipe 720 of the first heat exchange module and the fourth end 722 of the liquid outlet main pipe 720 of the second heat exchange module are staggered in the horizontal direction.

[0168] In this way, the distance between the third end 721 of the first heat exchange module and the fourth end 722 of the second heat exchange module is larger, and the third end 721 of the first heat exchange module and the fourth end 722 of the second heat exchange module are connected more easily.

[0169] It can be understood that when the third end 721 of the first heat exchange module and the fourth end 722 of the second heat exchange module are staggered in the horizontal direction, the projection of the third end 721 of the first heat exchange module along the vertical direction is staggered with the projection of the fourth end 722 of the second heat exchange module along the vertical direction.

[0170] The third end 721 of the first heat exchange module and the fourth end 722 of the second heat exchange module can be staggered in the thickness direction of the cabinet door 320. The third end 721 of the first heat exchange module and the fourth end 722 of the second heat exchange module can be staggered in the width direction of the cabinet door 320. The third end 721 of the first heat exchange module and the fourth end 722 of the second heat exchange module can also be staggered in both the thickness and width directions of the cabinet door 320.

[0171] The third end 721 of the liquid outlet main pipe 720 of the first heat exchange module and the fourth end 722 of the liquid outlet main pipe 720 of the second heat exchange module may be connected via a second connecting pipe 740 .

[0172] Figure 7 This is a schematic diagram of the connection of multiple heat exchange modules of another electronic device provided in an embodiment of the present application. Figure 8 A schematic diagram of the connection between the liquid inlet pipe and the liquid outlet pipe of two adjacent heat exchange modules of another electronic device provided in an embodiment of the present application.

[0173] like Figure 7 、 Figure 8 As shown, in an embodiment of the present application, the first end 711 of the liquid inlet main pipe 710 of the first heat exchange module is connected to the second end 712 of the liquid inlet main pipe 710 of the second heat exchange module through a first connecting pipe 730, and the third end 721 of the liquid outlet main pipe 720 of the first heat exchange module is connected to the fourth end 722 of the liquid outlet main pipe 720 of the second heat exchange module through a second connecting pipe 740, and the first connecting pipe 730 and the second connecting pipe 740 are arranged crosswise.

[0174] In this way, the liquid inlet main pipe 710 and the liquid outlet main pipe 720 of the first heat exchange module and the second heat exchange module can occupy less space in the horizontal direction of the cabinet door 320, which is conducive to increasing the layout area of ​​the heat exchange tube 600.

[0175] For example, the first end 711 of the first heat exchange module and the fourth end 722 of the second heat exchange module may be vertically opposite each other, and the third end 721 of the first heat exchange module and the second end 712 of the second heat exchange module may be vertically opposite each other.

[0176] In this way, the horizontal space occupied by the liquid inlet main pipe 710 and the liquid outlet main pipe 720 of the first heat exchange module and the second heat exchange module in the cabinet door 320 can be further reduced, which is conducive to increasing the layout area of ​​the heat exchange tube 600.

[0177] It can be understood that when the first end 711 of the first heat exchange module and the fourth end 722 of the second heat exchange module are vertically opposite, the center of the projection of the first end 711 of the first heat exchange module in the vertical direction coincides with the center of the projection of the fourth end 722 of the second heat exchange module in the vertical direction.

[0178] When the third end 721 of the first heat exchange module and the second end 712 of the second heat exchange module are vertically opposite, the center of the projection of the third end 721 of the first heat exchange module in the vertical direction coincides with the center of the projection of the second end 712 of the second heat exchange module in the vertical direction.

[0179] As shown in the embodiment of the present application, the outer wall of the at least one heat exchange pipe 600 is provided with fins 630. Figure 5-7

[0180] In this way, the heat exchange efficiency of the heat exchange pipe 600 provided with fins 630 is high, which is beneficial to improve the heat dissipation performance of the electronic device 200.

[0181] It can be understood that in each heat exchange module 3221, the outer wall of each heat exchange pipe 600 can be provided with fins 630, or the outer wall of part of the heat exchange pipes 600 can be provided with fins 630, and the outer wall of part of the heat exchange pipes 600 can not be provided with fins 630.

[0182] In the embodiment in which the heat exchange pipe 600 is horizontally arranged, the fins 630 on the surface of the heat exchange pipe 600 can be vertically arranged.

[0183] In the embodiment of the present application, a plurality of fins 630 can be arranged at intervals in the extension direction of the heat exchange pipe 600, which is beneficial to improve the heat exchange efficiency of the heat exchange module 3221.

[0184] In some embodiments in which the heat exchange module 3221 includes a plurality of heat exchange pipes 600, each fin 630 can be connected to only one heat exchange pipe 600, and the fins 630 on the outer walls of adjacent two heat exchange pipes 600 can be arranged at intervals.

[0185] In this way, each heat exchange pipe 600 of the heat exchange module 3221 can be individually disassembled, and the heat exchange pipes 600 of the heat exchange module 3221 can be individually replaced.

[0186] Figure 9 Another connection diagram of a plurality of heat exchange modules of an electronic device is provided in the embodiment of the present application.

[0187] As shown in the embodiment of the present application, the outer wall of the at least one heat exchange pipe 600 is provided with fins 630. Figure 9 In some embodiments in which the heat exchange module 3221 includes a plurality of heat exchange pipes 600, at least one fin 630 in each heat exchange module 3221 is connected to at least two heat exchange pipes 600.

[0188] ​In this way, the heat exchange area of ​​the fin 630 connected to multiple heat exchange tubes 600 is larger, the heat exchange efficiency is high, and the temperature of each heat exchange tube 600 connected through the fin 630 is more balanced, which can make the heat exchange at each heat exchange tube 600 connected through the fin 630 more balanced, and the heat exchange performance of the heat exchange module 3221 is better.

[0189] It can be understood that, in each heat exchange module 3221 , each fin can be connected to at least two heat exchange tubes 600 .

[0190] In each heat exchange module 3221 , at least one fin 630 may be connected to all the heat exchange tubes 600 .

[0191] In the embodiment where the heat exchange module 3221 includes a plurality of heat exchange tubes 600 , all the heat exchange tubes 600 of the heat exchange module 3221 are arranged opposite each other. In each heat exchange module 3221 , each fin 630 is connected to all the heat exchange tubes 600 .

[0192] In this way, the heat exchange performance of the heat exchange module 3221 is better.

[0193] Figure 10 A schematic top view of a heat exchange module provided with an exhaust valve of another electronic device provided in an embodiment of the present application.

[0194] like Figure 10 As shown, in an embodiment of the present application, each heat exchange tube 600 includes multiple straight tube sections 610 and at least one elbow section 620 that connects the multiple straight tube sections 610 in series in sequence. The inlet end of the straight tube section 610 of the first section of the heat exchange tube 600 serves as the inlet end of the heat exchange tube 600, which is used to be connected to the output end of the refrigerant cooling system 500, and the outlet end of the straight tube section 610 of the tail section of the heat exchange tube 600 serves as the outlet end of the heat exchange tube 600, which is used to be connected to the input end of the refrigerant cooling system 500.

[0195] In this way, the extension length of each heat exchange tube 600 is longer, which is conducive to extending the flow time of the refrigerant in the heat exchange tube 600, and helping the refrigerant flowing in the heat exchange tube 600 absorb more heat, and the heat exchange efficiency of the heat exchange module 3221 is higher.

[0196] It can be understood that each of the adjacent straight pipe sections 610 at both ends is connected in series via an elbow section 620 , and the number of the elbow sections 620 is one less than the number of the straight pipe sections 610 .

[0197] The straight pipe section 610 and the elbow section 620 can be connected by welding or flange structures.

[0198] It can be understood that all the straight sections 610 of the heat exchange tube 600 can be parallel to each other, and the heat exchange tube 600 including the straight sections 610 and the elbow sections 620 can extend in a serpentine shape.

[0199] All straight pipe sections 610 of the heat exchange pipe 600 can be parallel to the thickness direction of the cabinet door 320 and arranged in sequence along the width direction of the cabinet door 320. All straight pipe sections 610 of the heat exchange pipe 600 can also be parallel to the width direction of the cabinet door 320 and arranged in sequence along the thickness direction of the cabinet door 320.

[0200] The straight pipe sections 610 and the elbow sections 620 of the horizontally arranged heat exchange pipe 600 are all horizontal.

[0201] When the heat exchange module 3221 includes the liquid inlet main pipe 710 and the liquid outlet main pipe 720, in each heat exchange module 3221, the inlet end of the first straight pipe section 610 of the heat exchange pipe 600 is in communication with the liquid inlet main pipe 710, and the outlet end of the last straight pipe section 610 of the heat exchange pipe 600 is in communication with the liquid outlet main pipe 720.

[0202] For example, the heat exchange pipe 600 includes 6 straight pipe sections 610 and 5 elbow sections 620, the 6 straight pipe sections 610 are parallel to each other, and the 6 straight pipe sections 610 are respectively a first straight pipe section, a second straight pipe section, a third straight pipe section, a fourth straight pipe section, a fifth straight pipe section, and a sixth straight pipe section, the 5 elbow sections are respectively a first elbow section, a second elbow section, a third elbow section, a fourth elbow section, and a fifth elbow section, the first straight pipe section is the first straight pipe section 610 of the heat exchange pipe 600, the inlet end of the first straight pipe section is the inlet end of the heat exchange pipe 600, and is used to communicate with the output end of the refrigerant cooling system 500, the sixth straight pipe section is the last straight pipe section 610 of the heat exchange pipe 600, and the outlet end of the sixth straight pipe section is the outlet end of the heat exchange pipe 600, and is used to communicate with the input end of the refrigerant cooling system 500, the two ends of the first elbow section are respectively in communication with the outlet end of the first straight pipe section and the inlet end of the second straight pipe section, the two ends of the second elbow section are respectively in communication with the outlet end of the second straight pipe section and the inlet end of the third straight pipe section, the two ends of the third elbow section are respectively in communication with the outlet end of the third straight pipe section and the inlet end of the fourth straight pipe section, the two ends of the fourth elbow section are respectively in communication with the outlet end of the fourth straight pipe section and the inlet end of the fifth straight pipe section, and the two ends of the fifth elbow section are respectively in communication with the outlet end of the fifth straight pipe section and the inlet end of the sixth straight pipe section.

[0203] In the embodiment in which the fins 630 are arranged on the outer wall of the heat exchange pipe 600, the fins 630 can be arranged only on the outer wall of the straight pipe section 610, or the fins 630 can be arranged on the outer wall of both the straight pipe section 610 and the elbow section 620.

[0204] In some examples in which the heat exchange pipe 600 includes multiple straight pipe sections 610, the fins arranged on the straight pipe section 610 can be connected only to one straight pipe section 610, and the fins 630 on the outer walls of adjacent two straight pipe sections 610 can be arranged at intervals.

[0205] Figure 11A schematic top view of a heat exchange module provided with an exhaust valve of another electronic device provided in an embodiment of the present application.

[0206] like Figure 11 As shown, in some examples where the heat exchange tube 600 includes multiple straight tube sections 610, at least one fin 630 is provided on the outer wall of the straight tube section 610, and in each heat exchange tube 600, at least one fin 630 on the outer wall of the straight tube section 610 is connected to at least two straight tube sections 610.

[0207] In this way, the heat exchange area of ​​the fins 630 connecting the multiple straight pipe sections 610 of the heat exchange tube 600 is larger, the heat exchange efficiency is higher, and the temperature of the straight pipe sections 610 connected by the fins 630 is more balanced, which can make the heat exchange at the straight pipe sections 610 connected by the fins 630 more balanced, and the heat exchange performance of the heat exchange tube 600 is better.

[0208] It is understandable that a plurality of fins 630 may be provided on the outer wall of the straight pipe section 610 at intervals along its extending direction.

[0209] In each heat exchange tube 600 , each fin on the outer wall of the straight tube section 610 may be connected to at least two straight tube sections 610 .

[0210] In each heat exchange tube 600 , at least one fin 630 on the outer wall of the straight tube section 610 may connect all the straight tube sections 610 .

[0211] In the embodiment of the present application, all the straight tube sections 610 of the heat exchange tube 600 are arranged opposite each other. In each heat exchange tube 600 , each fin 630 on the outer wall of the straight tube section 610 is connected to all the straight tube sections 610 .

[0212] In this way, the heat exchange performance of the heat exchange tube 600 is better.

[0213] refer to Figure 12-18 The door body 321 may be provided with a first outlet 3211 extending through the door body 321. The air outlet of the heating device 400 mentioned above may be in communication with the first outlet 3211 of the door body 321. The heat exchanger 322 may be disposed between the air outlet of the heating device 400 and the first outlet 3211 of the cabinet door 320 to reduce the air temperature in the computer room 100 where the electronic equipment 200 is located.

[0214] It's worth noting that the temperature of the liquid in heat exchanger 322 is lower than the air temperature in the equipment room 100, causing a large number of water droplets to form on the outer wall of heat exchanger 322. Under the airflow from the internal duct of cabinet 300, these water droplets can fly out of first outlet 3211 of cabinet door 320, wetting nearby personnel. To address this issue, the cabinet door 320 provided in this embodiment of the application is provided with a liquid shield 323 to prevent the water droplets from flying out.

[0215] Figure 12 For Figure 2 Another schematic view of the electronic device is shown. Referring to Figure 12 , the first flow outlet can be multiple, and the multiple first flow outlets can be spaced apart along the second direction Y. The liquid blocking cover 323 can be multiple, and the multiple liquid blocking covers 323 can correspond to the multiple first flow outlets one by one. And Figure 12 Each first flow outlet can be shielded by a corresponding liquid blocking cover 323.

[0216] Optionally, at least part of the number of first flow outlets can be a group, and the first flow outlets in the group can correspond to one heat exchange module 3221. Figure 12 In the case where the multiple first flow outlets are divided into three groups, the three groups of first flow outlets correspond to the three heat exchange modules 3221 one by one.

[0217] Optionally, the door body 321 can include a metal layer and a plastic layer connected together, as Figure 12 As shown in the dashed box, the area corresponding to the heat exchange module 3221 is the plastic layer, and the rest is the metal layer. The wind shield 323 can be made of plastic material, and the wind shield 323 and the injection molding layer can be made into an integral piece by using an integral molding process such as injection molding. Alternatively, the door body 321 and the wind shield 323 can be made of metal material, and the door body 321 and the wind shield 323 can be made into an integral piece by using an integral molding process.

[0218] Figure 13 A first cross-sectional view of part of the door body 321 and the liquid blocking cover 323 of the cabinet door 320 provided by the embodiment of the present application is provided. Referring to Figure 13 The door body 321 can be provided with a first flow outlet 3211, and the first flow outlet 3211 can penetrate the door body 321 along the first direction X. That is, the axis of the first flow outlet 3211 is along the first direction X, and the fluid in the accommodation space can be blown out from the first flow outlet 3211 along the first direction X. In other words, the fluid leaving the first flow outlet 3211 flows along the first direction X.

[0219] In addition, the door body 321 is generally plate-shaped, and the first direction X can be the thickness direction of the door body 321. In addition, the second direction Y is perpendicular to the first direction X, and when the electronic device is placed on a support surface (such as the ground, etc.), one end of the door body 321 in the second direction Y can be towards the support surface, and the other end of the door body 321 in the second direction Y can be away from the support surface. The end of the door body 321 towards the support surface can be referred to as the bottom end of the door body 321, and the end of the door body 321 away from the support surface can be referred to as the top end of the door body 321.

[0220] Continuing to refer to Figure 13, the liquid-blocking cover 323 can be arranged on the side of the door body 321 away from the heating device 400. Moreover, the liquid-blocking cover 323 can be arranged to cover the first outflow port 3211. That is to say, the projection of the first outflow port 3211 on the inner wall surface of the liquid-blocking cover 323 along the first direction X can be located within the inner wall surface of the liquid-blocking cover 323. In other words, in the second direction Y, the orthographic projection of the liquid-blocking cover 323 on the surface of the door body 321 is longer than or equal to the first outflow port 3211. Furthermore, in the second direction Y, the orthographic projection of the liquid-blocking cover 323 on the surface of the door body 321 is longer than the first outflow port 3211. In addition, the liquid-blocking cover 323 can be made of plastic material.

[0221] In this way, the fluid flowing out of the first outlet 3211 along the first direction X can be blocked by the inner wall surface of the liquid blocking cover 323. In addition, since the density of the gas portion and the liquid portion in the fluid blown out of the first outlet 3211 are different, when the fluid is blown from the first outlet 3211 along the first direction X toward the liquid blocking cover 323, the gas portion in the fluid will bend and flow along the inner wall surface of the liquid blocking cover 323 (such as Figure 13 The liquid portion of the fluid will hit the liquid shield 323 due to inertia and then flow along the inner wall of the liquid shield 323. In this way, the gas portion of the fluid is separated from the liquid portion, reducing the water content of the fluid blown out of the cabinet door 320.

[0222] In addition, a channel 324 may be formed between the liquid shield 323 and the door body 321. The fluid that has passed through the heat exchanger 322 and exchanged heat with the heat exchanger 322 may enter the channel 324 through the first outlet 3211 and flow out of the channel 324. The channel 324 may be formed in the following ways:

[0223] In one possible implementation of channel 324, reference Figure 13 and Figure 14 One end of the liquid blocking cover 323 along the second direction Y is connected to the door body 321, and the other end of the liquid blocking cover 323 along the second direction Y exceeds the first flow outlet 3211 and forms a channel 324 between the door body 321, and the channel 324 can be connected to the first flow outlet 3211.

[0224] For example, refer to Figure 13 The liquid shield 323 may have a top and a bottom that are oppositely disposed along the second direction. The top of the liquid shield 323 may be connected to the door body 321 , and the bottom of the liquid shield 323 may exceed the bottom of the first outflow port 3211 and form a channel 324 with the door body 321 .

[0225] Specifically, the separated liquid and gas parts mentioned above can both flow out through the channel 324 (as shown by the dotted line ①). In addition, since the bottom end of the liquid shield 323 exceeds the bottom end of the first flow outlet 3211, the gas part of the fluid flowing out through the bottom end of the first flow outlet 3211 can be as shown in FIG. Figure 13 The middle dotted line ② shows a bend. However, the liquid portion of the fluid flowing out of the bottom end of the first outlet 3211 will continue to move in the first direction X due to inertia. This is to further separate the gas and liquid portions of the fluid and reduce the water content of the fluid blown out of the cabinet door 320.

[0226] Optionally, a third outlet 3233 may be provided at the bottom of the liquid shield 323. The third outlet 3233 may penetrate the liquid shield 323 so that part of the fluid can flow out. Figure 13 As shown by the dotted line ③ in the figure, the liquid flows out from the third outlet 3233 to increase the air flow rate of the liquid shield 323. The top surface of the third outlet 3233 can be lower than the bottom surface of the first outlet 3211 to prevent the fluid from being blown out from the third outlet 3233 along the first direction.

[0227] Figure 14 for Figure 13 The front view of the liquid shield 323 of the electronic device 200 is shown. Figure 13 and Figure 14 The bottom end surface of the third flow outlet 3233 can be flush with the bottom end surface of the liquid blocking cover 323, so as to further increase the air outlet of the liquid blocking cover 323 and facilitate the liquid part of the fluid to flow out from the bottom end of the third flow outlet 3233.

[0228] In addition, there may be multiple third outlets 3233 , and the multiple third outlets 3233 may be spaced apart along a third direction perpendicular to the plane where the first direction and the second direction are located, so that the fluid flows out evenly along the third direction.

[0229] Figure 15 This is a cross-sectional view of a portion of the door body 321 and the liquid shield 323 of the second cabinet door 320 provided in an embodiment of the present application. Figure 15 In another exemplary embodiment, the bottom end of the liquid blocking cover 323 may be connected to the door body 321 , and the top end of the liquid blocking cover 323 may exceed the top end of the first flow outlet 3211 and form a channel 324 between the liquid blocking cover 323 and the door body 321 .

[0230] Specifically, a portion of the gas in the fluid flowing out of the first outlet 3211 along the first direction can be as follows: Figure 15 The dotted line ① in the middle shows a bend and is separated from the liquid portion of the fluid, and then flows out through the channel 324.

[0231] Continue to refer Figure 15Optionally, a fifth outlet 3236 may be provided at the bottom of the liquid shield 323. The fifth outlet 3236 may penetrate the liquid shield 323 so that part of the fluid can flow out. Figure 15 As shown by the dotted line ② in FIG, the liquid flows out from the fifth outlet 3236 to increase the air flow rate of the liquid shield 323. The top surface of the fifth outlet 3236 can be lower than the bottom surface of the first outlet 3211 to prevent the fluid from being blown out from the fifth outlet 3236 along the first direction.

[0232] Figure 16 This is a cross-sectional view of a portion of the door body 321 and the liquid shield 323 of the third cabinet door 320 provided in an embodiment of the present application. Figure 16 In another possible implementation of the channel 324, the bottom end of the liquid-blocking cover 323 may extend beyond the bottom end of the first outflow port 3211, and a channel 324 may be formed between the bottom end of the liquid-blocking cover 323 and the door body 321. The top end of the liquid-blocking cover 323 may extend beyond the top end of the first outflow port 3211, and a channel 324 may be formed between the top end of the liquid-blocking cover 323 and the door body 321.

[0233] Specifically, a portion of the fluid flowing out of the first outlet 3211 of the door body 321 may flow out of the channel 324 at the top (refer to FIG. Figure 16 The other part flows out from the channel 324 at the bottom (as shown by the dotted line ①). Figure 16 In this way, the cabinet 310 has a large air outlet area and has the advantage of high heat dissipation efficiency.

[0234] In order to connect the liquid shield 323 and the door body 321, the liquid shield 323 and the door body 321 can be connected through a bracket 325. The bracket 325 can be as follows Figure 16 As shown, the first outlet 3211 is arranged on both sides of the second direction Y and / or the third direction Z.

[0235] certainly, Figure 16 The liquid blocking cover 323 may also be provided with an outflow port that penetrates the liquid blocking cover 323 to increase the air outlet area of ​​the cabinet door 320. The top surface of the outflow port may be lower than the bottom surface of the first outflow port 3211 to prevent the fluid from being blown out from the outflow port along the first direction.

[0236] Figure 17 This is a cross-sectional view of a portion of the door body 321 and the liquid shield 323 of the fourth cabinet door 320 provided in an embodiment of the present application. Figure 17 In another possible implementation of the channel 324, the liquid-blocking cover 323 and the door body 321 may be combined to form an accommodation space. The liquid-blocking cover 323 may be provided with a second flow outlet 3234. The second flow outlet 3234 may be located to one side of the first flow outlet 3211 in the second direction, and the second flow outlet 3234 and the first flow outlet 3211 may be connected through the accommodation space.

[0237] Specifically, since the bottom end of the liquid barrier 323 is beyond the bottom end of the first flow outlet 3211, the gas portion in the fluid flowing out of the bottom end of the first flow outlet 3211 can be bent as shown by the dashed line① in the middle. And the liquid portion in the fluid flowing out of the bottom end of the first flow outlet 3211 will continue to move in the first direction due to inertia. So as to further separate the gas portion and the liquid portion in the fluid, and reduce the water content of the fluid blowing out of the cabinet door 320. Figure 17

[0238] Wherein, the second flow outlet 3234 can be lower than the first flow outlet 3211 as shown in the middle, or the second flow outlet 3234 is at least two, at least one second flow outlet 3234 is lower than the first flow outlet 3211, and at least one second flow outlet 3234 is higher than the first flow outlet 3211. Figure 17

[0239] Exemplarily, the liquid barrier 323 can include a side wall 3231 and a bottom wall 3232. Wherein, the side wall 3231 can be arranged at one side of the first flow outlet 3211 in the first direction, and the bottom wall 3232 can be arranged at one side or both sides of the first flow outlet 3211 in the second direction. And the bottom wall 3232 can be connected between the bottom end of the side wall 3231 (and / or the top end of the side wall 3231) and the door body 321, and can be provided with the second flow outlet 3234. Figure 17 Exemplarily, the bottom wall 3232 is connected between the bottom end of the side wall 3231 and the door body 321 is exemplified in the middle. In addition, in order to improve the separation of the gas portion and the liquid portion in the fluid, the bottom wall 3232 and the end face of the first flow outlet 3211 in the second direction can have a certain spacing. In addition, the connection mode between the bottom wall 3232 and the door body 321 can be welding, bonding, made by an integral molding process, etc.

[0240] Optionally, the axis of the second flow outlet 3234 can intersect the axis of the first flow outlet 3211, so as to separate the gas portion and the liquid portion in the fluid. Further, the axis of the second flow outlet 3234 can be perpendicular to the axis of the first flow outlet 3211, so as to further separate the liquid portion and the gas portion in the fluid.

[0241] Optionally, in order to further improve the air volume of the door body 321, the side wall 3231 of the liquid barrier 323 can be provided with a fourth flow outlet 3235 penetrating through the side wall 3231 of the liquid barrier 323. At least part of the fluid flowing out of the first flow outlet 3211 can flow out of the fourth flow outlet 3235 as shown by the dashed line② in the middle. Wherein, the fourth flow outlet 3235 can be lower than the bottom end of the first flow outlet 3211, so as to reduce the content of the liquid portion in the fluid flowing out. Figure 17

[0242] Reference​​​Figure 13-17 Optionally, the at least partial liquid baffle 323 can be opposite to the first flow outlet 3211 and can have an inner arc wall, which can have an arc center towards the first flow outlet 3211. In this way, the fluid flowing out of the channel 324 can flow towards the door body 321, so as to further avoid the fluid directly blowing on the user. It should be noted that the above-mentioned several possible implementations of the liquid baffle 323 can all have an inner arc wall.

[0243] Optionally, the width of the first flow outlet 3211 can be along the second direction, and the length of the first flow outlet 3211 can be along the third direction. The length of the first flow outlet 3211 can be longer than the width of the first flow outlet 3211. The cross-sectional shape of the first flow outlet 3211 in the YZ plane can be rectangular or elliptical. When the first flow outlet 3211 is elliptical, the width of the first flow outlet 3211 can decrease from the middle to both ends, so that the fluid is concentrated from the middle. In addition, the liquid baffle 323 needs to cover the first flow outlet 3211, and the shape of the liquid baffle 323 can be set according to the shape of the first flow outlet 3211. When the first flow outlet 3211 is elliptical, the liquid baffle 323 can also be elliptical. Exemplarily, Figure 15 Optionally, the width of the liquid baffle 323 can decrease from the middle to both ends.
