Description

Technical Field

[0001] The present invention relates to the technical field of heat pipes and heat exchangers, and in particular to a heat pipe air conditioner and a machine room having the same. Background Art

[0002] A heat pipe air-conditioner is a high-efficiency air-conditioner based on heat pipe technology. One end of the heat pipe is the evaporation end, and the other end is the condensation end. When the evaporation end is heated, the liquid in it quickly vaporizes into steam due to the increase in temperature. The steam flows to the condensation end under the action of pressure difference or gravity. The steam releases heat at the condensation end and condenses into liquid again. The liquid then flows back to the evaporation end along the porous material by capillary action. This cycle continues until the temperatures at both ends of the heat pipe are equal (at this time, the heat diffusion of the steam stops). This cycle is carried out quickly and heat can be conducted continuously.

[0003] In the relevant technology, in data centers and traditional communication rooms, there are many types of air conditioning terminal products based on heat pipe air conditioning technology (such as room-level heat pipe air conditioners, heat pipe row air conditioners, heat pipe backplane air conditioners, heat pipe cold (wind) walls, etc.). Heat pipes are divided into two categories according to the different working fluid drive forms: gravity heat pipes and power heat pipes. Gravity heat pipes do not require external power. The refrigerant liquid relies on its own gravity to return from the condensation section to the evaporation section, and the working fluid circulates by itself. Power heat pipes require a fluorine pump (liquid pump) to increase the circulation power.

[0004] However, the heat exchange efficiency of air-conditioning terminal products based on heat pipe air-conditioning technology in related technologies is not high in data centers and traditional communication rooms. Summary of the invention

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In the relevant technologies, from the perspective of improving heat exchange efficiency, the design and development idea of ​​the heat pipe air conditioner in the computer room in the relevant technologies is to get closer and closer to the heat source, such as from the room level, to the row level, to the cabinet level, and then to the chip level. Different types of heat pipe air conditioners are at different distances from the heat source, which greatly affects their heat exchange efficiency.

[0035] like Figures 1 to 5 As shown, an embodiment of the present invention provides a heat pipe air conditioner, which includes an indoor main unit 10 and a folding wing 20. The indoor main unit 10 has a heat exchange cavity 11 and a heat exchange inlet 12 and a heat exchange outlet 13 connected to the heat exchange cavity 11. One end of the folding wing 20 is connected to the indoor main unit 10, and the other end of the folding wing 20 can be connected to the rack 30. When the folding wing 20 is in an unfolded state, the folding wing 20, the indoor main unit 10 and the rack 30 together form a local hot air cavity 40. The heat exchange inlet 12 is arranged on the side wall of the indoor main unit 10 facing the inside of the local hot air cavity 40, and the heat exchange outlet 13 is arranged on the side wall of the indoor main unit 10 facing the outside of the local hot air cavity 40.

[0036] The heat pipe air conditioner provided in this embodiment is applied, and the racks 30 are arranged side by side in the machine room, and there is a rack walkway 31 between two adjacent racks 30. The heat pipe air conditioner includes an indoor host 10 and a folding wing 20. The heat pipe air conditioner is arranged in the rack walkway 31. When the heat pipe air conditioner is working, the folding wing 20 is switched to the unfolded state, so that the folding wing 20, the indoor host 10 and the rack 30 together form a local hot air cavity 40, and the folding wing 20 is used to block and guide the hot air flow generated by the rack 30 to flow to the heat exchange inlet 12, and the hot air flow enters the indoor host 10 through the heat exchange inlet 12, and then the indoor host 10 performs heat exchange with the hot air flow to cool the hot air flow, and the cooled air flow is discharged into the rack walkway 31 through the heat exchange outlet 13. Therefore, the present application uses the folding wing 20 in the unfolded state to guide and collect the hot air generated by the rack 30 in a large range, guide the hot air flow to the indoor host 10, and improve the heat exchange efficiency of the heat pipe air conditioner in the machine room.

[0037] It should be noted that the temperature distribution of the rack 30 during operation is uneven. The present application sets the indoor host 10 close to the high-temperature area of ​​the rack 30 so that the local hot air cavity 40 is set corresponding to the high-temperature area of ​​the rack 30, and utilizes the folding wings 20 in the unfolded state to guide and collect the hot air generated by the rack 30 over a large area, thereby preventing the hot air flow from flowing freely in the machine room and guiding the hot air flow to the indoor host 10, which can shorten the path of the hot air flow to the indoor host 10 and improve the heat exchange efficiency of the heat pipe air conditioner in the machine room.

[0038] In this embodiment, the heat pipe air conditioner is arranged in the rack aisle 31 and close to the back of the rack 30. The folding wings 20 are switched to the unfolded state, so that the folding wings 20, the indoor host 10 and the back of the rack 30 together form a local hot air cavity 40, wherein the back panel of the rack 30 is removed to facilitate the hot air flow of the rack 30 to enter the local hot air cavity 40, and when it is necessary to inspect and maintain the equipment in the rack, the end of the folding wing 20 and the rack 30 are separated, and the folding wing 20 is switched to the folded state, so that personnel can enter the local hot air cavity 40 to inspect and maintain the equipment in the rack.

[0039] like Figure 2As shown, the folding wing 20 is provided with a vent 21 connecting the inside and outside of the local hot air cavity 40, and a shutter 22 is swingably provided at the vent 21. The folding wing 20 has a screen state and a ventilation state. When the folding wing 20 is in the screen state, the shutter 22 closes the vent 21, and when the folding wing 20 is in the ventilation state, the shutter 22 opens the vent 21. When the folding wing 20 is in the screen state, the shutter 22 closes the vent 21, and at this time, the hot air in the local hot air cavity 40 flows to the heat exchange inlet 12 under the guiding effect of the shutter 22, and the hot air flow enters the indoor host 10 through the heat exchange inlet 12, and then the indoor host 10 performs heat exchange with the hot air flow to cool the hot air flow, and the cooled air flow is discharged into the rack aisle 31 through the heat exchange outlet 13. When the folding wings 20 are in the ventilation state, the shutters 22 open the vents 21. At this time, the hot air in the local hot air cavity 40 can flow out through the vents 21 to enhance the air flow inside the factory and achieve heat exchange between the local hot air cavity 40 and the rest of the space inside the factory.

[0040] like Figure 2 and Figure 5 As shown, the folding wing 20 includes at least two foldable wing plates 23, the wing plates 23 include two cross beams 231 and two vertical beams 232, the two cross beams 231 are arranged opposite to each other, the two vertical beams 232 are arranged opposite to each other, the two ends of the cross beam 231 are respectively connected to the two vertical beams 232, the two ends of the vertical beam 232 are respectively connected to the two cross beams 231, the cross beams 231 and the vertical beams 232 together form a vent 21, the shutter member 22 includes a driving member 221 and at least two wind guide shutters, and the at least two wind guide shutters are arranged opposite to each other. The louvers are arranged on the cross beam 231 along the extension direction of the cross beam 231, the air guide louvers are swingably arranged relative to the cross beam 231, the swing axis of the air guide louvers and the air guide louvers both extend along the extension direction of the vertical beam 232, when the folding wings 20 are in the screen state, at least two air guide louvers close the vents 21, and when the folding wings 20 are in the ventilation state, at least two air guide louvers open the vents 21, and the driving member 221 is arranged on the wing plate 23 and is drivingly connected to the at least two air guide louvers.

[0041] The driving member 221 is used to drive at least two wind guide louvers to swing, so as to open and close the vents 21, so that remote control operation can be achieved and the operation intensity of personnel can be reduced.

[0042] Specifically, the length of the horizontal beam 231 is 30 cm, the length of the vertical beam 232 is 2 m, the thickness of the wing plate 23 is 2 cm, and the wing plate 23 and the shutter 22 are both made of metal.

[0043] In this embodiment, the driving member 221 includes a 24V DC motor.

[0044] like Figure 5As shown, the heat pipe air conditioner further includes a first temperature sensor 32 and a controller 33. The first temperature sensor 32 is arranged in the local hot air cavity 40. The controller 33 is respectively connected to the first temperature sensor 32 and the driving member 221 by signals, so as to control the driving member 221 to work according to the detection result of the first temperature sensor 32. When the first temperature sensor 32 detects that the temperature in the local hot air cavity 40 is lower than the dangerous threshold, the controller 33 controls the driving member 221 to drive at least two air guide louvers to close the vent 21. At this time, the hot air in the local hot air cavity 40 flows to the heat exchange inlet 12 under the guiding effect of the louver 22. The hot air flows into the indoor host 10 through the heat exchange inlet 12, and then the indoor host 10 performs heat exchange with the hot air flow to cool the hot air flow. The cooled air flow is discharged into the rack aisle 31 through the heat exchange outlet 13, thereby improving the heat exchange efficiency. When the first temperature sensor 32 detects that the temperature in the local hot air chamber 40 is greater than or equal to the danger threshold, the controller 33 controls the driving member 221 to drive at least two air guide louvers to open the vents 21. At this time, the hot air in the local hot air chamber 40 flows out through the vents 21 to enhance the air flow inside the factory, quickly balance the temperature distribution inside the factory, avoid excessive local temperature, and avoid high temperature damage to the components of the rack that are arranged close to the local hot air chamber 40.

[0045] like Figures 1 to 3 As shown, the folding wing 20 includes at least two wing panels 23 arranged along the extension direction of the rack walkway 31, and the two adjacent wing panels 23 of the folding wing 20 are hinged, and the wing panel 23 of the at least two wing panels 23 of the folding wing 20 that is arranged close to the indoor host 10 is hinged to the indoor host 10, and the wing panel 23 of the at least two wing panels 23 of the folding wing 20 that is arranged away from the indoor host 10 can be connected to the rack 30. The above-mentioned at least two wing panels 23 form a structure similar to a vertical screen, which is convenient for quickly folding and storing or unfolding the folding wing 20 for use.

[0046] In the relevant technologies, heat pipe air conditioners have a common feature (regional cooling, lack of flexibility, once installed and operated, the location is basically fixed, and the ability to adapt to the dynamic changes of the heat load of the later computer room is relatively poor). Take the heat pipe backplane air conditioner as an example:

[0047] (1) The heat pipe backplane air conditioner is part of the overall structure of the rack. If the equipment in the rack needs to be inspected and maintained, the backplane needs to be opened and closed. As time goes by, the number of times the backplane is opened and closed is proportional to the probability of hose leakage;

[0048] (2) In the event of a power outage or a logic freeze in the control system of the heat pipe backplane air conditioner, the cooling fans of the heat pipe backplane air conditioner will shut down due to a group failure. At this time, the backplane itself will become a heat dissipation barrier for the rack, causing the equipment in the rack to heat up sharply, and in severe cases, causing the equipment to shut down;

[0049] (3) The single back plate of the heat pipe back plate air conditioner can generally only serve a single rack (except for the mixed air cabin). The rack and the back plate provide cooling one-to-one, and the back plate cannot be moved. When the rack loading rate is not high in the early stage of production, it is easy to cause waste like a big horse pulling a small cart.

[0050] like Figure 3 As shown, the heat pipe air conditioner further includes a moving track 50 extending along the extension direction of the rack aisle 31, and the indoor host 10 has a moving state and a working state. When the indoor host 10 is in the moving state, the indoor host 10 is movably arranged on the moving track 50 along the extension direction of the moving track 50, and when the indoor host 10 is in the working state, the position of the indoor host 10 on the moving track 50 is fixed. By switching the indoor host 10 to the moving state, separating the end of the folding wing 20 and the rack 30, and moving the indoor host 10 along the extension direction of the moving track 50, it is convenient to adjust the position of the indoor host 10 in the rack aisle 31 according to the use requirements, and when the indoor host 10 moves into place, the indoor host 10 is switched to the working state, which is convenient to fix the position of the indoor host 10 in the rack aisle 31, thereby improving the deployment flexibility of the indoor host 10.

[0051] Specifically, the temperature distribution of the rack 30 changes with time during operation. The indoor host 10 is moved along the extension direction of the movable track 50. The position of the indoor host 10 in the rack aisle 31 can be adjusted according to the temperature distribution change of the rack 30, so that the indoor host 10 can move with the high temperature area of ​​the rack 30 and dynamically adapt to the heat dissipation requirements of the back of a whole row of racks 30.

[0052] like Figure 3 As shown, the movable track 50 includes a hanging rail 51 and a hanging pulley 52, the hanging rail 51 is arranged above the indoor host 10, the hanging rail 51 extends along the extension direction of the rack walkway 31, the hanging pulley 52 includes a hanging member 521 and a pulley member 522, the lower end of the hanging member 521 is connected to the indoor host 10, the pulley member 522 is rotatably arranged on the hanging member 521, and the pulley member 522 is slidably arranged on the hanging rail 51 along the extension direction of the hanging rail 51. The movable track 50 (similar to the hanging sliding door of home decoration) with the above structure can reduce the movement resistance of the indoor host 10 and the folding wing 20 by rolling the pulley member 522.

[0053] The hanging member 521 includes a hanging rod, both ends of which are respectively connected to the pulley member 522 and the indoor host 10 . When the indoor host 10 is in a moving state, the hanging rod is used to bear the weight of the indoor host 10 and the folding wing 20 .

[0054] In this embodiment, the hanging rail 51 includes a slide cross bar and a lifting vertical bar. The two ends of the slide cross bar are hard-connected and fixed to the roof through two hard lifting vertical bars. The slide cross bar is made of metal cold-rolled profile. The upper surface of the slide cross bar is provided with a slide groove extending along its length direction. The pulley member 522 is slidably arranged in the slide groove along the extension direction of the slide groove.

[0055] Specifically, the distance between the slide groove cross bar and the back side of the rack 30 is 30 cm, and the height difference between the slide groove cross bar and the ground is greater than or equal to 2.6 m.

[0056] like Figure 2 and Figure 3 As shown, the heat pipe air conditioner further includes a movable leg 60, which is arranged at the lower end of the indoor main unit 10 and / or the lower end of the folding wing 20. When the indoor main unit 10 is in a moving state, the movable leg 60 is retracted upward relative to the indoor main unit 10, and when the indoor main unit 10 is in a working state, the movable leg 60 is extended downward relative to the indoor main unit 10. By adjusting the movable leg 60, the movable leg 60 is raised and lowered relative to the indoor main unit 10, so as to realize the switching of the indoor main unit 10 between the moving state and the working state.

[0057] In this embodiment, the movable leg 60 includes a leg member and a nut member. The nut member is rotatably arranged at the lower end of the indoor main unit 10 and / or the lower end of the folding wing 20. The leg member is inserted into the nut member and is threadedly engaged with the nut member. The leg member is anti-rotatably engaged with the indoor main unit 10 or the folding wing 20. When the nut member rotates, the leg member can be raised and lowered relative to the indoor main unit 10 or the folding wing 20. When the indoor main unit 10 is in a moving state, the lower end of the leg member is separated from the ground. When the indoor main unit 10 is in a working state, the lower end of the leg member is in contact with the ground to bear the weight of the indoor main unit 10 and the folding wing 20, thereby enhancing the placement stability of the heat pipe air conditioner.

[0058] Specifically, when the nut member is rotated, the adjustment stroke of the leg member is 0 cm to 2 cm.

[0059] In this embodiment, four movable legs 60 are disposed at the lower end of the indoor host 10 , and two movable legs 60 are disposed at the lower end of each wing plate 23 .

[0060] like Figures 2 to 4As shown, the indoor host 10 includes a cabinet 14 and a heat exchanger 15 and a DC fan 16 arranged in the cabinet 14. The cabinet 14 is provided with a liquid pipe interface 141 and an air pipe interface 142 connected to the heat exchanger 15. The heat exchange cavity 11, the heat exchange inlet 12 and the heat exchange outlet 13 are all arranged on the cabinet 14. One end of the folding wing 20 is connected to the cabinet 14. The heat pipe air conditioner also includes a circulation pipeline 70. The circulation pipeline 70 includes a main air pipe 71, a main liquid pipe 72, a flexible air pipe 73 and a flexible liquid pipe 74. The main air pipe 71 has at least two reserved air inlets 711 arranged at intervals along the extension direction of the rack aisle 31. The reserved air inlet 711 is provided with a first One-way valve, the main liquid pipe 72 has at least two reserved liquid receiving ports 721 arranged at intervals along the extension direction of the rack aisle 31, and the at least two reserved liquid receiving ports 721 are arranged in a one-to-one correspondence with the at least two reserved air receiving ports 711. A second one-way valve is arranged at the reserved liquid receiving port 721, one end of the flexible air pipe 73 is connected to the air pipe interface 142, and the other end of the flexible air pipe 73 can be selectively connected to one of the at least two reserved air receiving ports 711, one end of the flexible liquid pipe 74 is connected to the liquid pipe interface 141, and the other end of the flexible liquid pipe 74 can be selectively connected to one of the at least two reserved liquid receiving ports 721.

[0061] Among them, since the other end of the flexible air pipe 73 can be selectively connected to one of the at least two reserved air ports 711, and the other end of the flexible liquid pipe 74 can be selectively connected to one of the at least two reserved liquid ports 721, when adjusting the position of the indoor host 10 in the rack aisle 31 according to the use requirements, it is convenient to select the reserved air port 711 and the reserved liquid port 721 nearby to connect the heat exchanger 15 and the main air pipe 71, and connect the heat exchanger 15 and the main liquid pipe 72. When the reserved air port 711 and the reserved liquid port 721 are not connected for use, the reserved air port 711 and the reserved liquid port 721 can be closed by using the first one-way valve and the second one-way valve.

[0062] Furthermore, by providing at least two reserved liquid receiving ports 721 and at least two reserved air receiving ports 711, rapid expansion of multiple indoor hosts 10 can be achieved, dynamically adapting to the heat dissipation requirements of the back of a whole row of racks.

[0063] In this embodiment, the spacing between two adjacent reserved air ports 711 is 3 meters, the spacing between two adjacent reserved liquid ports 721 is 3 meters, both ends of the flexible air pipe 73 and both ends of the flexible liquid pipe 74 are provided with quick connectors, the length of the flexible air pipe 73 is greater than or equal to 2 meters, the length of the flexible liquid pipe 74 is greater than or equal to 2 meters, the main air pipe 71 and the main liquid pipe 72 are both arranged above the indoor host 10, and the main air pipe 71 and the main liquid pipe 72 are both arranged parallel to the extension direction of the rack aisle 31, the main air pipe 71 and the main liquid pipe 72 are both made of high-quality copper pipes brazed and welded, the pressure bearing capacity of the main air pipe 71 and the main liquid pipe 72 is greater than 2.5MPa, and the installation and acceptance standards of the circulation pipeline 70 refer to relevant national requirements and enterprise standards.

[0064] like Figure 4 As shown, the heat pipe air conditioner also includes an outdoor unit 90. The outdoor unit 90 is similar to the outdoor unit of a traditional air conditioner. The outdoor unit 90 mainly includes a condenser and an outdoor fan. The main air pipe 71 and the main liquid pipe 72 are extended to the outdoors and connected to the condenser. The indoor heat load absorbed by the heat exchanger 15 is transferred to the outdoors through the condenser. The heat pipe working fluid in the circulation pipeline 70 completes the refrigeration cycle through gravity or a pump. If the heat pipe working fluid in the circulation pipeline 70 completes the refrigeration cycle through gravity, the installation height of the outdoor unit 90 needs to be greater than the installation height of the indoor host 10.

[0065] In this embodiment, the effective heat dissipation area of ​​the outdoor unit 90 is greater than or equal to 1.2 times the effective heat dissipation area of ​​the indoor host 10 .

[0066] like Figures 1 to 3 As shown, the heat pipe air conditioner includes two folding wings 20, which are respectively arranged on both sides of the indoor host 10 along the extension direction of the rack aisle 31. In this embodiment, the two folding wings 20 and the indoor host 10 can enclose a local hot air chamber 40 behind the five adjacent rack units.

[0067] In this embodiment, each folding wing 20 includes five wing panels 23 arranged along the extension direction of the rack aisle 31 .

[0068] like Figures 2 to 5As shown, the indoor host 10 includes a cabinet 14, a heat exchanger 15 and a DC fan 16 arranged in the cabinet 14, the heat exchange cavity 11, the heat exchange inlet 12 and the heat exchange outlet 13 are all arranged on the cabinet 14, one end of the folding wing 20 is connected to the cabinet 14, and the heat pipe air conditioner also includes a second temperature sensor and a controller 33. The second temperature sensor is arranged on the heat exchanger 15, and the controller 33 is respectively connected to the second temperature sensor and the DC fan 16 signal to control the DC fan 16 to work according to the detection result of the second temperature sensor. The heat exchanger is the heat exchange main body of the heat pipe air conditioner. The hot air flow enters the indoor host 10 through the heat exchange inlet 12, and the hot air flow exchanges heat with the heat exchanger 15 to cool the hot air flow. The cooled air flow is driven by the DC fan 16 and discharged into the rack aisle 31 through the heat exchange outlet 13. Among them, the controller 33 controls the start and stop and the speed of the DC fan 16 according to the detection result of the second temperature sensor.

[0069] Specifically, when the second temperature sensor detects that the temperature at the heat exchanger 15 is greater than or equal to the heat exchange threshold, the controller 33 controls the DC fan 16 to turn on or speed up, so that the hot air in the local hot air cavity 40 is quickly discharged through the heat exchange inlet 12 and the heat exchange outlet 13, to achieve forced exhaust and heat dissipation, to strengthen the air flow inside the plant, to quickly balance the temperature distribution inside the plant, to avoid excessive local temperature, and to avoid high temperature damage to the components of the racks arranged near the local hot air cavity 40. When the second temperature sensor detects that the temperature at the heat exchanger 15 is lower than the heat exchange threshold, the controller 33 controls the DC fan 16 to turn off or slow down.

[0070] Specifically, the cabinet body 14 is made of metal, the width of the cabinet body 14 is 60 cm, the length of the cabinet body 14 is 30 cm, and the height of the cabinet body 14 is 2 m.

[0071] In this embodiment, the indoor host 10 includes eight DC fans 16 .

[0072] like Figure 2 As shown, the indoor host 10 includes a cabinet 14, a heat exchanger 15 and a DC fan 16 arranged in the cabinet 14, the heat exchange cavity 11, the heat exchange inlet 12 and the heat exchange outlet 13 are all arranged on the cabinet 14, one end of the folding wing 20 is connected to the cabinet 14, and the indoor host 10 also includes a water collecting tank arranged in the cabinet 14, the water collecting tank is located below the heat exchanger 15, and a drain port 143 connected to the water collecting tank is also arranged on the cabinet 14. The condensed water generated by the heat exchange of the heat exchanger is collected by the water collecting tank, and the condensed water is uniformly discharged through the drain port 143 to improve the cleanliness of the environment.

[0073] like Figures 1 to 4As shown, the cabinet 14 has a front, a back and two side surfaces, wherein the front and the two side surfaces are arranged toward the inside of the local hot air cavity 40, and the back surface is arranged toward the outside of the local hot air cavity, a heat exchange inlet is arranged on the front and the two side surfaces, and a heat exchange outlet is arranged on the back surface.

[0074] In this embodiment, the heat exchanger 15 includes a microchannel heat exchanger. Among them, the microchannel heat exchanger (microchannel heat exchanger), as a type of plate heat exchanger, is a common high-efficiency heat exchanger in the refrigeration field. The working principle is to use the coupling effect between the fluid friction resistance, mixed heat and conduction heat in the microchannel to achieve heat exchange. Compared with the traditional plate heat exchanger, the use of a microchannel heat exchanger can make the fluid and heat transfer faster, thereby improving the heat exchange efficiency.

[0075] like Figure 2 , Figure 4 as well as Figure 5 As shown, the heat pipe air conditioner further includes a touch screen 80, which is arranged on the side wall of the indoor host 10 outside the local hot air cavity 40. The touch screen 80 is connected to the controller 33 by signal, and the user can input a control signal to the controller 33 by operating the touch screen 80 to realize manual control operation of the heat pipe air conditioner.

[0076] In the related art, various air-conditioning terminal products based on heat pipe air-conditioning technology have the following characteristics:

[0077] (1) Room-level heat pipe air conditioners require a dedicated air conditioning room, which results in low utilization of the computer room. Room-level heat pipe air conditioners are far away from the heat source, which results in low average energy efficiency of the system. Room-level heat pipe air conditioners are immobile and use diffuse air supply, which results in low cooling flexibility. The operating space of room-level heat pipe air conditioners is generally not restricted, and the operation and maintenance difficulty is low.

[0078] (2) Heat pipe inter-row air conditioners occupy cabinet space, resulting in low utilization of the computer room. Heat pipe inter-row air conditioners are close to the cabinets for cooling, resulting in average system energy efficiency. Heat pipe inter-row air conditioners are embedded in the cabinets and cannot be moved (usually with cold / hot aisle closure), resulting in low cooling flexibility. Heat pipe inter-row air conditioners are embedded in the cabinets, with a compact internal structure, making maintenance and replacement difficult.

[0079] (3) Heat pipe backplane air conditioners do not occupy computer room space, which improves computer room utilization. Heat pipe backplane air conditioners directly absorb cabinet exhaust heat, greatly improving cooling efficiency and system average energy efficiency. Heat pipe backplane air conditioners are highly coupled with cabinets and cannot be moved (racks and backplanes are cooled one-to-one), which makes cooling flexibility low. Heat pipe backplane air conditioners have many maintenance points, making maintenance difficult and risky.

[0080] (4) The heat pipe air mixing cabin occupies part of the maintenance and repair passage, resulting in a medium utilization rate of the computer room. The average energy efficiency of the system with a short heat pipe air mixing cabin is lower than that of the heat pipe backplane air conditioner. The heat pipe air mixing cabin cannot be moved (multiple cabinet backplanes are shared, which improves safety). The heat pipe air mixing cabin is difficult to repair and has a medium risk.

[0081] (5) The heat pipe cold (wind) wall is installed against the wall or overhead, which improves the utilization rate of the computer room. The heat pipe cold (wind) wall is far away from the heat source, which makes the average energy efficiency of the system low. The heat pipe cold (wind) wall cannot be moved, which makes the cooling flexibility low. The operation and maintenance of the heat pipe cold (wind) wall are not restricted and the difficulty is low.

[0082] The heat pipe air conditioner provided by this embodiment has the following beneficial effects:

[0083] (1) The indoor host 10 is arranged close to the high temperature area of ​​the rack 30, so that the local hot air cavity 40 is arranged corresponding to the high temperature area of ​​the rack 30, so that the heat pipe air conditioner is arranged close to the heat source, and the folding wings 20 are switched to the unfolded state, so that the folding wings 20, the indoor host 10 and the rack 30 together form a relatively closed local hot air cavity 40, and the folding wings 20 collect the hot air generated by the rack 30 in a large range. At the same time, the DC fan 16 is turned on, and the hot air flow enters the indoor host 10 through the heat exchange inlet 12, and the hot air flow exchanges heat with the heat exchanger 15 to cool the hot air flow. The cooled air flow is driven by the DC fan 16 and discharged into the rack aisle 31 through the heat exchange outlet 13, and forced convection exhaust is performed to improve the heat exchange efficiency of the heat pipe air conditioner in the machine room.

[0084] (2) If the indoor host 10 fails, the temperature in the local hot air cavity 40 is detected by the first temperature sensor 32. If the temperature in the local hot air cavity 40 is greater than or equal to the danger threshold, the controller 33 controls the driving member 221 to drive at least two air guide shutters to open the vent 21. At this time, the hot air in the local hot air cavity 40 flows out through the vent 21 to strengthen the air flow inside the factory building, quickly balance the temperature distribution inside the factory building, avoid excessive local temperature, and avoid high temperature damage to the components of the rack arranged near the local hot air cavity 40;

[0085] (3) By adjusting the movable legs 60, the indoor host 10 can be switched between the mobile state and the working state, so that the position of the indoor host 10 in the rack aisle 31 can be adjusted according to the use requirements. By setting at least two reserved liquid receiving ports 721 and at least two reserved air receiving ports 711, it is convenient to select the reserved air receiving ports 711 and the reserved liquid receiving ports 721 nearby, and the rapid expansion of multiple indoor hosts 10 can be achieved. When a single indoor host 10 fails, it is convenient to quickly leave the system for local repair.

[0086] (4) In traditional integrated communication rooms, wireless base stations, etc., most racks are front-to-back air outlets. However, the power consumption of each rack in different areas of the same room is different. The power consumption of the same rack also changes dynamically as the equipment is put on and taken off the rack, which easily generates local hot spots. The present application can adjust the position of the indoor host 10 in the rack aisle 31 according to the temperature distribution change of the rack 30, so that the indoor host 10 can move with the high temperature area of ​​the rack 30, dynamically adapt to the heat dissipation requirements of the back of a whole row of racks 30, and suppress local hot spots;

[0087] (5) When it is necessary to inspect and maintain the equipment in the rack, the ends of the folding wings 20 and the rack 30 are separated, and the folding wings 20 are switched to a folded state, so that personnel can enter the local hot air chamber 40 to inspect and maintain the equipment in the rack. The indoor host 10 and the rack 30 are arranged at intervals, so that a walking gap of 50 cm to 90 cm is left between the indoor host 10 and the rack 30, which is convenient for daily maintenance and overhaul;

[0088] (6) The heat pipe air conditioner provided in this embodiment makes full use of the space of the rack aisle 31, improves the overall space utilization of the computer room, and saves the construction cost of the computer room. At the same time, in the process of updating old air conditioners, it can replace room-level air conditioners, heat pipe backplane air conditioners and other products.

[0089] like Figure 1 As shown, another embodiment of the present invention provides a machine room, which includes the heat pipe air conditioner provided above. In the machine room provided by this embodiment, racks 30 are arranged side by side in the machine room, and a rack walkway 31 is provided between two adjacent racks 30. The heat pipe air conditioner includes an indoor host 10 and a folding wing 20. The heat pipe air conditioner is arranged in the rack walkway 31. When the heat pipe air conditioner is working, the folding wing 20 is switched to the unfolded state, so that the folding wing 20, the indoor host 10 and the rack 30 together form a local hot air cavity 40. The folding wing 20 is used to block and guide the hot air flow generated by the operation of the rack 30 to flow to the heat exchange inlet 12. The hot air flow enters the indoor host 10 through the heat exchange inlet 12, and then the indoor host 10 performs heat exchange with the hot air flow to cool the hot air flow. The cooled air flow is discharged into the rack walkway 31 through the heat exchange outlet 13. Therefore, the present application utilizes the folding wings 20 in the unfolded state to collect the hot air generated by the rack 30 over a large area, guides the hot air flow to the indoor host 10, and improves the heat exchange efficiency of the heat pipe air conditioner in the machine room.
