A high-efficiency intelligent control cabinet for computer room cooling towers

Abstract

This utility model discloses a high-efficiency intelligent control cabinet for computer room cooling towers, which includes a cabinet body, an installation plate on the inner wall of the cabinet body, multiple installation components on the side wall of the installation plate, a radiation shield on the top of the cabinet body, and a monitoring component at the bottom of the inner cavity of the radiation shield. This high-efficiency intelligent control cabinet for computer room cooling towers allows electrical equipment to be slidably inserted into a DIN rail and secured. Pressing the moving block moves the guide block, causing the guide block to rotate along the spiral groove, which in turn rotates the locking plate. After inserting the DIN rail into the installation slot, releasing the moving block causes the spring's rebound force to move the moving block in the opposite direction, which in turn causes the guide block to rotate in the opposite direction, resetting and locking the locking plate at the other end of the rotating shaft to engage the DIN rail. This makes disassembly and assembly simpler and more convenient, facilitating maintenance and preventing damage that could affect the operation of the cooling tower. Furthermore, the monitoring component simultaneously detects dry-bulb temperature and relative humidity, facilitating precise control of the cooling tower and reducing measurement delays caused by traditional natural convection.

Description

Technical Field

[0001] This utility model relates to the field of cooling tower control technology, specifically to a high-efficiency intelligent control cabinet for computer room cooling towers. Background Technology

[0002] The energy efficiency standard for high-efficiency data centers is usually measured by COP (Coefficient of Performance), and high-efficiency data centers generally have a COP value controlled above 5.0. The main function of a high-efficiency chiller room is to provide cooling capacity. According to the law of conservation of energy, the chiller room generates at least an equal amount of heat while providing cooling capacity, and this heat needs to be dissipated through the cooling water system.

[0003] In existing technologies, the conventional approach is to use cooling pumps to deliver cooling water from the computer room to the cooling towers, where it dissipates heat. Given the relatively low power of the cooling tower fans, the conventional method is to operate at mains frequency or high / low speed. This results in significant fluctuations in cooling water temperature, failing to achieve optimal cooling performance. Furthermore, the number of cooling towers and fan operation are related to humidity and temperature, and since the cooling tower system and wet-bulb temperature sensors are both located on the roof, the cooling tower system can form a closed-loop control system.

[0004] Although the device has many beneficial effects, the following problems still exist: During the use of the device, the electrical equipment inside the intelligent control cabinet of the cooling tower is inconvenient to disassemble and repair, which can easily lead to damage and affect the operation of the cooling tower; secondly, the device is not convenient to accurately measure the temperature and relative humidity near the cooling tower, and it is not convenient to make precise control. Therefore, we propose an efficient intelligent control cabinet for computer room cooling towers. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the problems mentioned above, such as the inconvenience of disassembling and repairing the electrical equipment inside the intelligent control cabinet of the cooling tower, which can easily lead to damage affecting the operation of the cooling tower, and the difficulty in accurately measuring the temperature and relative humidity near the cooling tower, thus hindering precise control, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide a high-efficiency intelligent control cabinet for computer room cooling towers, which facilitates the disassembly, assembly, and maintenance of electrical equipment inside the intelligent control cabinet, avoids damage that may affect the operation of the cooling tower, facilitates accurate measurement of temperature and relative humidity near the cooling tower, and enables precise control of the cooling tower.

[0009] 2. Technical Solution:

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0011] A high-efficiency intelligent control cabinet for computer room cooling towers includes a cabinet body. An installation plate is provided on the inner wall of the cabinet body. Multiple installation components are provided on the side wall of the installation plate. Each installation component includes an installation groove formed in the side wall of the installation plate. A DIN rail is provided on the inner wall of the installation groove. Moving blocks are slidably connected to the top and bottom of the side wall of the installation plate. A spring is provided at the other end of each moving block located on the inner wall of the installation plate. A rotating shaft is slidably connected to the inner circumference of the moving block and rotatably connected to the inner wall of the installation plate. A spiral groove is formed on the outer circumference of the rotating shaft. A guide block is slidably connected to the inner wall of the spiral groove located on the inner circumference of the moving block. A retaining plate is provided at the other end of the rotating shaft. A radiation shield is provided on the top of the cabinet body. A monitoring component is provided at the bottom of the inner cavity of the radiation shield. A cabinet door is hinged to the side wall of the cabinet body. The concave shape of the DIN rail side wall facilitates wiring and avoids messy wiring that interferes with maintenance personnel.

[0012] As a preferred embodiment of the high-efficiency intelligent control cabinet for computer room cooling towers according to this utility model, the monitoring component includes a dual temperature and humidity meter. One end of the dual temperature and humidity meter has an air inlet pipe, one end of which has a first reducing pipe, and the other end of which has a second reducing pipe. The other end of the second reducing pipe has an air outlet pipe, and the inner wall of the air outlet pipe is provided with a honeycomb grid. The top of the dual temperature and humidity meter has a detection head that penetrates the outer wall of the second reducing pipe. The dual temperature and humidity meter is electrically connected to an external power source. The reducing pipes rely solely on natural airflow or small temperature differences for operation, eliminating the need for fans or motors, making it suitable for long-term battery-powered monitoring devices.

[0013] As a preferred embodiment of the intelligent control cabinet for a high-efficiency computer room cooling tower according to this utility model, the other side wall of the mounting plate is provided with a plurality of power connection screws, and the position of the power connection screws matches the position of the mounting groove.

[0014] As a preferred embodiment of the intelligent control cabinet for high-efficiency computer room cooling towers of this utility model, the dimensions of the DIN rail match the dimensions of the mounting groove, and the dimensions and positions of the clamping plate match the dimensions and positions of both ends of the DIN rail.

[0015] As a preferred embodiment of the intelligent control cabinet for a high-efficiency computer room cooling tower of this utility model, the top of the radiation shield is an umbrella-shaped metal sheet, and the inner wall of the bottom cavity of the radiation shield is coated with chrome.

[0016] In a preferred embodiment of the intelligent control cabinet for a high-efficiency cooling tower in this utility model, the inner diameter of the first reducing pipe near the second reducing pipe is smaller than the inner diameter of the other end, and the length of the first reducing pipe is smaller than the length of the second reducing pipe. The longer second reducing pipe allows for gradual deceleration of the airflow, smooth pressure recovery, and prevents turbulence from causing measurement noise.

[0017] As a preferred embodiment of the intelligent control cabinet for a high-efficiency computer room cooling tower according to this utility model, an electricity meter is provided on the side wall of the cabinet door, and a current transformer is provided at the bottom of the inner cavity of the cabinet, and the current transformer is electrically connected to the electricity meter.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This type of high-efficiency intelligent control cabinet for computer room cooling towers works by sliding the required electrical equipment into the DIN rail and locking it in place. Pressing the moving block moves the guide block, which in turn drives the rotating shaft to rotate along the spiral groove, causing the locking plate to rotate. After inserting the DIN rail into the mounting slot, the moving block is released, and the spring's rebound force drives the moving block to move in the opposite direction, which in turn drives the guide block to move in the opposite direction, causing the locking plate at the other end of the rotating shaft to rotate in the opposite direction and reset to lock the DIN rail. This makes disassembly and assembly simpler and more convenient, facilitates maintenance, and avoids damage that could affect the operation of the cooling tower.

[0021] This type of high-efficiency intelligent control cabinet for computer room cooling towers uses dual temperature and humidity meters to enable the detection head to detect the air, simultaneously measuring dry-bulb temperature and relative humidity for convenient and precise control of the cooling tower. Air enters the first variable-diameter pipe from the inlet duct, where the Bernoulli effect accelerates the airflow, forcing it to flow quickly through the detection head and reducing measurement delays caused by traditional natural convection. The airflow is then smoothly decelerated through the second variable-diameter pipe and discharged from the outlet duct. The honeycomb grid prevents eddy currents from forming, which could affect measurement stability. Attached Figure Description

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] This utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not be construed as limiting the scope of protection of this utility model.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of an intelligent control cabinet for a high-efficiency computer room cooling tower, including:

[0035] Please see Figures 1-5 This embodiment of a high-efficiency intelligent control cabinet for a computer room cooling tower includes a cabinet body 1. A mounting plate 2 is fixedly installed on the inner side wall of the cabinet body 1. Multiple mounting components 3 are mounted on the side wall of the mounting plate 2. Each mounting component 3 includes a mounting groove 301 formed in the side wall of the mounting plate 2. A DIN guide rail 302 is engaged with the inner side wall of the mounting groove 301. Moving blocks 303 are slidably connected to the top and bottom of the side wall of the mounting plate 2. A spring 304 is fixedly installed at the other end of the moving block 303 on the inner wall of the mounting plate 2. A rotating shaft 305 is slidably connected to the inner circumference of the moving block 303 and rotatably connected to the inner wall of the mounting plate 2. A spiral groove 306 is formed on the outer circumference of the rotating shaft 305. A guide block 307 is slidably connected to the inner wall of the spiral groove 306 on the inner circumference of the moving block 303. A retaining plate is fixedly installed at the other end of the rotating shaft 305. 308. A radiation shield 4 is fixed to the top of the cabinet 1. A monitoring component 5 is fixed to the bottom of the inner cavity of the radiation shield 4. A cabinet door 6 is hinged to the side wall of the cabinet 1. The required electrical equipment is slidably inserted into the DIN rail 302 and locked in place. Pressing the moving block 303 moves the guide block 307, which in turn drives the rotating shaft 305 to rotate along the spiral groove 306, thereby causing the locking plate 308 to rotate. After inserting the DIN rail 302 into the mounting slot 301, the moving block 303 is released. The rebound force of the spring 304 drives the moving block 303 to move in the opposite direction, which in turn drives the guide block 307 to move in the opposite direction, causing the locking plate 308 at the other end of the rotating shaft 305 to rotate in the opposite direction and reset and lock the DIN rail 302. This makes disassembly and assembly simpler and more convenient, facilitates maintenance, and avoids damage that may affect the operation of the cooling tower.

[0036] In some embodiments, the intelligent control cabinet includes a variety of electrical and electronic components, such as circuit breakers, switching power supplies, PLCs, frequency converters, RS485 filters, repeaters, terminal blocks, etc. Due to space limitations, such prior art is not described in detail. The layout of such prior art can be reasonably adapted to this solution and will not affect the normal operation of this solution.

[0037] It is worth noting that, in order to facilitate simultaneous detection of temperature and humidity for precise control, the monitoring component 5 specifically includes a dual temperature and humidity meter 501. An air inlet pipe 502 is fixedly mounted on one end of the top of the dual temperature and humidity meter 501. A first reducing pipe 503 is welded to one end of the air inlet pipe 502, and a second reducing pipe 504 is welded to the other end of the first reducing pipe 503. An air outlet pipe 505 is welded to the other end of the second reducing pipe 504. A honeycomb grid plate 506 is fixedly mounted on the inner circumference of the air outlet pipe 505. A detection head is fixedly mounted on the top of the dual temperature and humidity meter 501, penetrating the outer circumference of the second reducing pipe 504. 507. The dual temperature and humidity meter 501 is electrically connected to an external power supply. By turning on the dual temperature and humidity meter 501, the detection head 507 detects the air, simultaneously detecting the dry bulb temperature and relative humidity, which facilitates precise control of the cooling tower. Air enters the first reducer 503 from the air inlet duct 502, and the Bernoulli effect accelerates the airflow, forcing the air to flow quickly through the detection head 507, reducing the measurement delay caused by traditional natural convection. The airflow is then gently decelerated through the second reducer 504 and discharged from the air outlet duct 505. The honeycomb grid plate 506 prevents the formation of eddies that could affect measurement stability.

[0038] Next, to improve safety, specifically, the other side wall of the mounting plate 2 is threaded with multiple power connection screws 309. The positions of the power connection screws 309 match the positions of the mounting grooves 301. The required electrical equipment is connected to the grounding terminal through the power connection screws 309 to ensure safety.

[0039] Meanwhile, in order to improve the installation stability of the DIN rail 302, specifically, the size of the DIN rail 302 matches the size of the mounting groove 301, and the size and position of the clamping plate 308 match the size and position of both ends of the DIN rail 302. By using two clamping plates 308 that match the size and position of both ends of the DIN rail 302, the installation of the DIN rail 302 is made more stable, avoiding shaking that could cause electrical equipment to fall and be damaged.

[0040] Furthermore, in order to reduce the interference of solar radiation on the measurement of the dual temperature and humidity meter 501, specifically, the top of the radiation shield 4 is an umbrella-shaped metal plate, and the inner wall of the bottom cavity of the radiation shield 4 is coated with chromium. The top of the radiation shield 4 with the umbrella-shaped metal plate helps to prevent solar radiation from directly shining on the dual temperature and humidity meter 501 and affecting the measurement results. The chromium coating and oxidation reduces sunlight reflection.

[0041] It is worth noting that, in order to facilitate the accelerated flow of air, specifically, the inner diameter of the first reducing pipe 503 near the second reducing pipe 504 is smaller than the inner diameter of the other end, and the length of the first reducing pipe 503 is smaller than the length of the second reducing pipe 504. By using the first reducing pipe 503, which is shorter than the second reducing pipe 504, it is easier to reach the maximum flow velocity at the throat with only a short acceleration, and to avoid the second reducing pipe 504 being too long and increasing frictional resistance.

[0042] Finally, to facilitate the measurement of cooling tower data, specifically, a meter 7 is threadedly connected to the side wall of cabinet door 6, and a current transformer 8 is threadedly connected to the bottom of the inner cavity of cabinet body 1. The current transformer 8 is electrically connected to the meter 7. The meter 7, which is electrically connected to the current transformer 8, is used to measure the operating voltage, current, power and power consumption of the cooling tower.

[0043] In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0044] The device or equipment models mentioned in this article may be as follows:

[0045] Dual temperature and humidity meter 501: TA318.

[0046] Combination Figures 1-5 The specific usage process of the high-efficiency intelligent control cabinet for computer room cooling towers in this embodiment is as follows:

[0047] 1. When this device is needed for use as an intelligent control cabinet for a high-efficiency cooling tower in a computer room, slide the required electrical equipment into the DIN rail 302 and lock it in place. Press the moving block 303 to move the guide block 307 along the spiral groove 306, causing the rotating shaft 305 to rotate, thereby causing the clamping plate 308 to rotate. After inserting the DIN rail 302 into the mounting slot 301, release the moving block 303. The rebound force of the spring 304 causes the moving block 303 to move in the opposite direction, thereby causing the guide block 307 to move in the opposite direction, causing the clamping plate 308 at the other end of the rotating shaft 305 to rotate in the opposite direction and lock the DIN rail 302.

[0048] 2: Start the dual temperature and humidity meter 501 so that the detection head 507 can simultaneously detect the dry bulb temperature and relative humidity of the air. The air enters the first variable diameter pipe 503 from the air inlet pipe 502 and flows through the detection head 507 quickly and rapidly. The airflow passes through the second variable diameter pipe 504 and decelerates slowly before being discharged from the air outlet pipe 505. A honeycomb grid plate 506 is installed on the inner circumference of the air outlet pipe 505.

[0049] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
