Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, and in particular to an integrated heat dissipation and noise reduction cabinet for UPS power supplies in computer rooms. Background Technology

[0002] Uninterruptible power supply (UPS) systems serve as the core of power protection for critical equipment, and their reliability directly affects the stable operation of environments such as data centers and server rooms. UPS cabinets are the key physical infrastructure housing the UPS main unit, battery banks, and supporting power distribution and management systems. Since the UPS main unit generates a large amount of heat during power conversion, and the battery banks are extremely sensitive to operating temperature, the heat dissipation performance of the UPS cabinet directly determines the system's efficiency, component lifespan, and overall reliability. Existing UPS cabinets generally adopt an integrated airflow design, using cooling fans installed inside or outside the cabinet to provide unified or simple zoned forced air cooling for the UPS main unit and battery banks. This design approach places the entire focus on active cooling, which can meet basic cooling requirements under high loads, but its system architecture has inherent limitations, failing to achieve an optimal balance between cooling efficiency, energy consumption, and noise control.

[0003] Furthermore, traditional forced air cooling designs often focus on cooling the main heat source (i.e., the UPS host) while neglecting the cooling required for the battery pack. This results in the cooling systems of the two areas being independent of each other, increasing structural complexity. In addition, the high-temperature airflow generated by the UPS host under high load conditions can easily cause thermal shock to the adjacent battery pack, thereby affecting the chemical performance and lifespan of the battery.

[0004] Therefore, it is necessary to invent an integrated heat dissipation and noise reduction cabinet for UPS power supplies in computer rooms to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated heat dissipation and noise reduction cabinet for UPS power supplies in computer rooms, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated heat dissipation and noise reduction cabinet for a computer room UPS power supply, comprising:

[0007] The main body of the cabinet has a partition inside. The cabinet body also houses a battery pack and a UPS main unit. The battery pack is located above the UPS main unit, and both the battery pack and the UPS main unit are located on one side of the partition.

The bottom end of the heat dissipation air duct is fixedly provided with an air inlet pipe, and the air inlet pipe is located on one side of the UPS main unit group. The top end of the heat dissipation air duct is fixedly provided with an air exhaust pipe, and the top end of the air exhaust pipe is fixedly provided with an adjustable-speed fan. Multiple through slots are opened in the middle of the outer side wall of the heat dissipation air duct, and the multiple through slots are all located outside the battery pack. The bottom end of the heat dissipation air duct is fixedly provided with a heat-conducting copper pipe. One end of the heat-conducting copper pipe is fixedly provided with a heat-conducting copper plate, and the lower surface of the heat-conducting copper plate is fitted with the upper surface of the UPS main unit group. The other end of the heat-conducting copper pipe is fixedly provided with heat dissipation fins, and the heat dissipation fins are located inside the heat dissipation air duct;

[0009] An air inlet cover is fixedly provided at the bottom end of the outer side wall of the cabinet main body and is communicated with the inside of the cabinet main body;

[0010] Multiple rotatable air guiding plates are provided and are sequentially arranged from bottom to top inside the air inlet cover.

[0011] Preferably, an air guiding block is fixedly provided at the bottom end of the rotatable air guiding plate. The rotatable air guiding plate is provided with a "factory" - shaped structure, and multiple rotatable air guiding plates are stacked from bottom to top. A cold air inlet channel is formed between the bottom end of the air guiding block and the top end of the rotatable air guiding plate;

[0012] Multiple air guiding holes are provided and are all provided at the bottom end of the air guiding block. The air guiding holes are used to ensure that cold air can pass through the multiple rotatable air guiding plates and enter the cabinet main body.

[0013] Preferably, an adjusting motor is fixedly provided at the top end inside the air inlet cover, and the output shaft of the adjusting motor is connected to one end of a rotatable air guiding plate;

[0014] Multiple swing arms are provided and are respectively fixedly provided at one end of the multiple rotatable air guiding plates;

[0015] A transmission arm is provided inside the air inlet cover. One end of each of the multiple swing arms is rotatably connected to the transmission arm through a pin shaft. The adjusting motor is used to provide power for the rotation of the rotatable air guiding plate, and the swing arm and the transmission arm are used to realize the transmission between the multiple rotatable air guiding plates.

[0016] Preferably, two air inlets are provided and are both provided on the side of the air inlet pipe close to the UPS main unit group. The two air inlets are respectively located on both sides of the UPS main unit group.

[0017] Preferably, an extension air duct is fixedly provided on the outside of the air exhaust pipe and is communicated with the inside of the air exhaust pipe, and the bottom end of the extension air duct is located outside the heat dissipation air duct;

[0018] An adjustable baffle is rotatably provided inside the extension air duct. The extension air duct is used to realize the connection between the battery pack and the air exhaust pipe;

[0019] The start-stop motor is fixedly installed on the outside of the extension duct, and the output shaft of the start-stop motor is connected to the bottom end of the adjustable baffle.

[0020] Preferably, there are multiple air guide ducts, all located inside the heat dissipation air duct. The multiple air guide ducts are located at the openings of multiple through slots, and the multiple air guide ducts are all designed with a conical structure.

[0021] Multiple bends are provided, each fixedly located at the end of the air guide hopper away from the through channel.

[0022] Preferably, the bevel is located at the top of the side of the bend away from the air guide duct;

[0023] The guide channel is provided in multiple ways and is located on the side of the bend away from the air guide hopper. The hot air flowing from bottom to top inside the heat dissipation duct is accelerated after passing through the guide channel, which makes the end of the guide channel near the inclined opening form a negative pressure. Under the action of negative pressure, the air outside the battery pack is drawn into the heat dissipation duct and discharged through the through channel, air guide hopper and bend.

[0024] Preferably, the heat dissipation fins are provided in multiple sets, and all sets of heat dissipation fins are provided in an inclined structure.

[0025] Preferably, a dustproof net is fixedly installed inside the air inlet hood, and a grille door is fixedly installed on the outside of the air inlet hood.

[0026] Preferably, the outer side of the main cabinet body is provided with two rotatable maintenance doors, and the two maintenance doors are respectively located on both sides of the partition. A heat insulation plate is provided between the battery pack and the UPS main unit, and the heat insulation plate is fixedly installed on one side of the partition.

[0027] The technical effects and advantages of this invention are as follows:

[0028] 1. This invention integrates the low-heat-generating battery pack and the high-heat-generating UPS main unit inside the cabinet body by adopting an upper and lower layout. This layout not only makes the airflow smoother and reduces airflow resistance, but also prevents the UPS main unit and the battery pack from interfering with each other. By setting up a heat dissipation air duct inside the cabinet body and setting an air inlet hood at the bottom of the outer side of the cabinet body, the outside cold air reaches the outside of the UPS main unit through the air inlet hood, and the original hot air on the outside of the UPS main unit enters the heat dissipation air duct for exhaust. The chimney effect formed inside the heat dissipation air duct accelerates the exhaust of hot air. With the above structure in combination, the UPS main unit can be cooled by air convection, thereby effectively relieving the working pressure of the adjustable speed fan and thus reducing equipment noise.

[0029] 2. This invention sets multiple through slots on the outside of the heat dissipation duct, and each slot opening is equipped with a guide hopper and a bend. When hot air from outside the UPS main unit is discharged through the heat dissipation duct, the airflow speed inside the duct is accelerated due to the chimney effect formed inside the duct. At this time, a low-pressure area is formed at the end of the bend under the Venturi effect, which causes the slightly warmer air from outside the battery pack to enter the heat dissipation duct and be discharged together under the Venturi effect. Synchronous heat dissipation of the UPS main unit and the battery pack can be achieved through a set of heat dissipation ducts, and the heat generated by the UPS main unit is used as the power source for heat dissipation. While ensuring the heat dissipation effect of the device, the noise of the device during operation is effectively reduced.

[0030] 3. This invention, by setting up an extended air duct, allows the adjustable baffle inside the extended air duct to connect the outside of the battery pack with the inside of the heat dissipation air duct after flipping. At this time, the adjustable speed fan can directly draw hot air from the outside of the battery pack to meet the heat dissipation requirements of the device when operating at high power consumption. By setting a rotatable air guide plate inside the air inlet shroud, when the device is operating at low power consumption, the rotatable air guide plate can be rotated to a larger angle to avoid hot air backflow affecting airflow. When the device is operating at high power consumption, the rotatable air guide plate can be rotated to a smaller angle to increase the amount of cold air entering, thereby meeting the heat dissipation requirements of the device under different operating conditions.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] like Figures 1 to 12 As shown, the integrated heat dissipation and noise reduction cabinet for UPS power supply in a computer room provided by the present invention is essentially a cabinet that achieves heat dissipation of the UPS main unit 13 through air convection to alleviate the working pressure of the adjustable speed fan 23 and thus reduce equipment noise. By adopting a top-bottom layout, the low-heat-generating battery pack 12 and the high-heat-generating UPS main unit 13 are integrated inside the cabinet body 1. This layout not only makes the airflow smoother and reduces airflow resistance, but also ensures that the UPS main unit 13 and the battery pack 12 do not interfere with each other. A heat dissipation air duct 2 is set inside the cabinet body 1, and an air inlet hood 3 is set at the bottom of the outer side of the cabinet body 1. After the outside cold air reaches the outside of the UPS main unit 13 through the air inlet hood 3, the original hot air on the outside of the UPS main unit 13 enters the heat dissipation air duct for exhaust. The chimney effect formed inside the heat dissipation air duct accelerates the exhaust of hot air, thereby achieving the effect of heat dissipation of the UPS main unit 13 through air convection.

[0046] In terms of specific structural installation, the structural body can be constructed according to the inventive concept of this embodiment. In this embodiment, no special limitations are imposed.

[0047] In this embodiment, a UPS power supply heat dissipation and noise reduction integrated cabinet for computer rooms includes:

[0048] The main body of the cabinet 1 has a partition 11 inside. The main body of the cabinet 1 also has a battery pack 12 and a UPS main unit 13 inside. The battery pack 12 is located above the UPS main unit 13, and both the battery pack 12 and the UPS main unit 13 are located on one side of the partition 11. A heat insulation plate 14 is provided between the battery pack 12 and the UPS main unit 13, and the heat insulation plate 14 is fixedly installed on one side of the partition 11.

[0049] The outer side of the main cabinet 1 is provided with two rotatable maintenance doors, which are located on both sides of the partition 11. The partition 11 divides the interior of the main cabinet 1 into two parts. The two maintenance doors correspond to the power section consisting of the battery pack 12 and the UPS host 13, and the heat dissipation section consisting of the heat dissipation duct 2, respectively. When performing maintenance on different work areas, only the corresponding maintenance door needs to be opened, and the two work areas do not interfere with each other, so as to facilitate the maintenance of the device.

[0050] A heat dissipation duct 2 is located inside the main cabinet 1 and on the other side of the partition 11. An air inlet pipe 21 is fixedly installed at the bottom of the heat dissipation duct 2, and the air inlet pipe 21 is located on one side of the UPS main unit 13. An exhaust pipe 22 is fixedly installed at the top of the heat dissipation duct 2, and an adjustable speed fan 23 is fixedly installed at the top of the exhaust pipe 22. Multiple through slots 25 are opened in the middle of the outer wall of the heat dissipation duct 2, and all through slots 25 are located on the outside of the battery pack 12. A heat-conducting copper pipe 26 is fixedly installed at the bottom of the heat dissipation duct 2, and a heat-conducting copper plate 261 is fixedly installed at one end of the heat-conducting copper pipe 26. The lower surface of the heat-conducting copper plate 261 is flush with the bottom surface of the battery pack 12. The upper surface of the UPS main unit 13 is attached to the heat-conducting copper pipe 26, and the other end of the heat-conducting copper pipe 26 is fixed with heat dissipation fins 262. The heat dissipation fins 262 are located inside the heat dissipation duct 2. There are multiple sets of heat dissipation fins 262, and all sets of heat dissipation fins 262 are designed with an inclined structure. The inclined structure design increases the contact area between the rising hot air inside the heat dissipation duct 2 and the heat dissipation fins 262, thereby improving the heat exchange effect of the device. At the same time, some of the heat generated by the UPS main unit 13 during operation can be discharged through the heat-conducting copper plate 261, the heat-conducting copper pipe 26 and the heat dissipation fins 262 to improve the heat dissipation effect of the UPS main unit 13.

[0051] The air inlet 211 has two inlets, both located on the side of the air inlet pipe 21 close to the UPS main unit 13. The two air inlets 211 are located on both sides of the UPS main unit 13. The arrangement of the two air inlets 211 allows hot air from both sides of the UPS main unit 13 to be discharged, thereby accelerating the airflow speed.

[0052] An extension duct 24 is fixedly installed on the outside of the exhaust duct 22 and communicates with the inside of the exhaust duct 22, and the bottom end of the extension duct 24 is located on the outside of the heat dissipation duct 2.

[0053] An adjustable baffle 241 is rotatably disposed inside the extension duct 24, which is used to connect the battery pack 12 and the exhaust duct 22.

[0054] The start-stop motor 242 is fixedly installed on the outside of the extension duct 24, and the output shaft of the start-stop motor 242 is connected to the bottom end of the adjustable baffle 241. The start-stop motor 242 can drive the adjustable baffle 241 to rotate. When the adjustable baffle 241 is rotated to the vertical state, the internal channel of the extension duct 24 is opened.

[0055] Multiple air guide hoppers 251 are provided and are all located inside the heat dissipation air duct 2. The multiple air guide hoppers 251 are located at the slot openings of multiple through slots 25, and the multiple air guide hoppers 251 are all designed with a conical structure.

[0056] Multiple bends 252 are provided and each is fixedly located at the end of the air guide hopper 251 away from the through groove 25;

[0057] The oblique opening 253 is located at the top of the side of the bend 252 away from the air guide 251. The oblique opening 253 makes the top of the side of the bend 252 away from the air guide 251 form a smaller area, thereby amplifying the low-pressure area formed by the Venturi effect, so as to ensure that the air outside the battery 12 is extracted.

[0058] The guide channel 254 is provided in multiple ways and is located on the side of the bend 252 away from the air guide hopper 251. The hot air flowing from bottom to top inside the heat dissipation air duct 2 is accelerated after passing through the guide channel 254, which makes the end of the guide channel 254 near the inclined opening 253 form a negative pressure. Under the action of negative pressure, the air outside the battery pack 12 is drawn into the heat dissipation air duct 2 and discharged through the through channel 25, air guide hopper 251 and bend 252.

[0059] The air inlet hood 3 is fixedly installed at the bottom of the outer side wall of the cabinet body 1 and communicates with the interior of the cabinet body 1;

[0060] The air inlet shroud 3 is equipped with a dustproof net 31 inside and a grille door 32 is equipped with a grille door 32 on the outside of the air inlet shroud 3. The grille door 32 ensures the electromagnetic shielding effect of the air inlet shroud 3 while realizing air flow.

[0061] Rotatable air guide plate 4, which is provided in multiple sets and arranged sequentially from bottom to top inside the air inlet hood 3;

[0062] The air guiding block 41 is fixedly arranged at the bottom end of the rotatable air guiding plate 4. The rotatable air guiding plate 4 is arranged in an "L" shape structure, and multiple rotatable air guiding plates 4 are stacked from bottom to top. An air inlet channel for cold air is formed between the bottom end of the air guiding block 41 and the top end of the rotatable air guiding plate 4;

[0063] There are multiple air guiding holes 42, and they are all arranged at the bottom end of the air guiding block 41. The air guiding holes 42 are used to ensure that cold air can pass through multiple rotatable air guiding plates 4 and enter the cabinet body 1. When the upper and lower rotatable air guiding plates 4 are stacked with each other, cold air can still enter the interior of the cabinet body 1 through the air guiding holes 42. In this state, hot air is blocked by the inclined inner wall of the rotatable air guiding plate 4 and cannot be guided;

[0064] The adjusting motor 43 is fixedly arranged at the inner top end of the air inlet cover 3, and the output shaft of the adjusting motor 43 is connected to one end of a rotatable air guiding plate 4;

[0065] There are multiple swing arms 44, and they are respectively fixedly arranged at one end of multiple rotatable air guiding plates 4;

[0066] The transmission arm 45 is arranged inside the air inlet cover 3. One end of multiple swing arms 44 is rotatably connected to the transmission arm 45 through a pin shaft. The adjusting motor 43 is used to provide the driving force for the rotation of the rotatable air guiding plate 4. The swing arms 44 and the transmission arm 45 are used to realize the transmission between multiple rotatable air guiding plates 4. The adjusting motor 43 can drive one rotatable air guiding plate 4 to rotate, and when the rotatable air guiding plate 4 rotates, it synchronously drives the swing arm 44 to rotate. Multiple swing arms 44 are linked through the transmission arm 45, so as to achieve the effect of synchronously rotating multiple rotatable air guiding plates 4.

[0067] When using the integrated heat dissipation and noise reduction cabinet for UPS power supply in this embodiment, the UPS main unit 13, which generates a large amount of heat, is located at the bottom of the cabinet body 1. The heat generated by the UPS main unit 13 heats the air at the bottom of the cabinet body 1. The heated air first gathers on the outside of the UPS main unit 13, and then the hot air diffuses into the air intake duct 21 through the air inlet 211. During this process, the outside cold air passes through the air intake shroud 3 and multiple rotatable air guide plates 4 and enters the bottom of the cabinet body 1. Due to the entry of the cold air, the hot air flows unidirectionally into the air intake duct 21, and then flows upward along the heat dissipation duct 2, and finally is discharged through the exhaust duct 22 at the top of the heat dissipation duct 2. During this process, the heat generated by the UPS main unit 13... Heat is exchanged with the air at the bottom of the heat dissipation duct 2 through the heat-conducting copper plate 261, the heat-conducting copper pipe 26, and the heat dissipation fins 262, causing the air temperature at the bottom of the heat dissipation duct 2 to rise, thus forming a high-pressure zone at the bottom of the heat dissipation duct 2. Since the UPS host unit 13 is in a state of continuous heat generation, the temperature at the three points of the outside of the UPS host unit 13, the bottom of the heat dissipation duct 2, and the top of the heat dissipation duct 2 decreases in sequence. Correspondingly, the air pressure at the three points of the outside of the UPS host unit 13, the bottom of the heat dissipation duct 2, and the top of the heat dissipation duct 2 decreases in sequence. At this time, a chimney effect is formed inside the heat dissipation duct 2, and the hot air is quickly discharged under the chimney effect. During this process, the heat generated by the operation of the UPS host unit 13 is quickly discharged under the action of air flow.

[0068] As hot air is rapidly discharged through the heat dissipation duct 2, its flow rate increases due to the chimney effect. The hot air, with its increased flow rate, flows along the outer wall of the bend 252 during its ascent. Under the Venturi effect, the high-speed hot air forms a low-pressure zone at the top of the bend 252. At this time, the air outside the battery pack 12, which is slightly cooler, is drawn into the heat dissipation duct 2 through the through slot 25, the air guide duct 251, and the bend 252 in sequence under the action of the air pressure difference. Then, it is discharged along with the hot air with a higher temperature. During this process, the heat generated by the operation of the battery pack 12 is also discharged.

[0069] The integrated heat dissipation and noise reduction cabinet for the UPS power supply in this embodiment has three working modes. In all three working modes, the heat dissipation duct 2 can achieve heat dissipation and cooling of the UPS host unit 13 and the battery pack 12 through air convection.

[0070] When the device is running in a low-power state, the battery pack 12 is in an energy storage state, the rectifier control pressure of the UPS host unit 13 is small, the UPS host unit 13 starts intermittently and generates less heat, the adjustable speed fan 23 is stopped, and the device dissipates heat only through air convection. The adjustable baffle 241 blocks the extended air duct 24 in this state, and the rotatable air guide plate 4 is at a large angle. Cold air can slowly enter through the air guide holes 42 between multiple rotatable air guide plates 4. The large angle of the rotatable air guide plate 4 can suppress the flow of hot air to ensure that the heat dissipation air duct 2 forms a chimney effect and smoothly discharges hot air. Since the adjustable speed fan 23 is stopped at this time, the device noise is extremely low.

[0071] When the device is running in the medium power consumption state, the battery pack 12 is in the charging state. The UPS host unit 13 needs to perform rectification to complete the charging of the battery pack 12. The heat generated by the UPS host unit 13 is slightly larger in this state. The adjustable speed fan 23 is running at a low speed in this state. The rotation of the adjustable speed fan 23 accelerates the flow of hot air inside the heat dissipation duct 2 to improve the heat dissipation efficiency of the device. In this state, the adjustable baffle 241 and the rotatable air guide plate 4 are in the same position as above. Since the speed of the adjustable speed fan 23 is low at this time, the noise of the device is low.

[0072] When the device operates in a high-power state, the battery pack 12 is in a discharging state. The UPS main unit 13 needs to operate at high power to ensure that the electrical energy stored in the battery pack 12 is quickly released to provide stable power to the outside. In this state, the UPS main unit 13 generates a lot of heat, and the battery pack 12 also generates heat due to discharge. In this state, the adjustable speed fan 23 operates at high speed, and at this time, the adjustable baffle 241 flips to open the internal channel of the extension duct 24. At this time, the outside of the battery pack 12 is connected to the inside of the heat dissipation duct 2. In this state, the adjustable speed fan 23 simultaneously draws power from the battery pack 12 and the UPS main unit. The hot air outside 13 is used to achieve synchronous heat dissipation of the battery pack 12 and the UPS host unit 13. At this time, the rotatable air guide plate 4 rotates to a horizontal position, and the gap between multiple rotatable air guide plates 4 increases, allowing cold air from the outside to quickly enter the cabinet body 1. Since the speed of the adjustable fan 23 is relatively high at this time, the noise of the device is slightly louder. It should be noted that the UPS power cabinet, as a backup energy storage device, mainly operates in low power and medium power states. This technical solution can achieve low noise operation in low power and medium power states, and can also reduce noise while ensuring heat dissipation in high power states.

[0073] It should be noted that the supporting structures such as the cabinet body 1, partition 11, and heat dissipation duct 2 in this embodiment are all manufactured using cold-rolled steel sheet metal processing. The power equipment such as the battery pack 12, UPS host unit 13, and adjustable speed fan 23 in this embodiment are all corresponding products in the prior art. Under the premise of ensuring the normal implementation of the technical solution of this embodiment, there is no limitation on the model of the above structures. The adjustable speed fan 23, the start-stop motor 242, and the regulating motor 43 in this embodiment are all equipped with controllers for control. The controller can be a PLC controller, which is equipped with a corresponding control program. It can control the adjustable speed fan 23, the start-stop motor 242, and the regulating motor 43 according to the working status of the UPS host unit 13. The above control logic adopts the prior art.

[0074] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
