Description

[0002] A large number of high-power electronic devices are usually densely arranged in a data center. When these electronic devices are continuously running, the heat generating elements inside the devices will generate a large amount of heat. When the heat dissipation efficiency is low, a large amount of heat will accumulate, causing the internal temperature of the device to exceed the safety threshold or the ambient temperature to abnormally rise, which can easily cause the electronic device to malfunction.

[0003] Generally, the heat exchange tube bundle in the dry cooler is arranged in a V shape, which has an aerodynamic design defect. During operation, the cooling return air discharged does not follow the preset flow channel circulation, but directly returns to the air inlet, forming a return air short circuit phenomenon. In this phenomenon, the cooling return air does not participate in effective heat exchange, which seriously affects the refrigeration efficiency. At the same time, the densely arranged dry cooler group continuously discharges high-temperature air flow, which forms a local heat island effect, reduces the heat exchange temperature difference, and causes the refrigeration efficiency to decrease.

[0004] To solve these problems, the existing solutions at least have the following problems: the dry cooler group needs to be raised by using hoisting equipment, and the guide pipe needs to be installed at the air outlet, and an auxiliary fan also needs to be installed.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] An embodiment of the present invention discloses a refrigeration system, comprising a plurality of dry coolers 1 arranged in a matrix structure, that is, all dry coolers 1 are arranged in a matrix structure.

[0045] As attached Figure 1 and 2 As shown, each dry cooler 1 is provided with an air inlet 101 and an air outlet 102, wherein the air inlet 101 can be provided on the side of the dry cooler 1, and the air outlet 102 can be provided on the top of the dry cooler 1. The low-temperature airflow from the external environment flows into the dry cooler 1 along the air inlet 101, exchanges heat with the dry cooler 1 to form a high-temperature airflow, and finally is discharged from the air outlet 102. In other words, the airflow mode of the dry cooler 1 is horizontal air inlet and vertical air outlet, wherein the horizontal air inlet can make the low-temperature airflow evenly distributed along the entire heat exchange surface of the dry cooler 1, avoiding local overheating or insufficient cooling of the heat exchange surface. The vertical air outlet causes the high-temperature airflow to form a chimney effect, naturally rising away from the air inlet 101, reducing the return air short-circuiting phenomenon. A protective cover is added to the air outlet 102 of each dry cooler 1 to prevent rainwater or dust from flowing back, making the operation of the dry cooler 1 more stable.

[0046] The matrix structure includes an outermost ring array facing the outside environment. The dry cooler 1 includes at least two outer dry coolers 11 distributed along the ring array. The air inlets 101 of the outer dry coolers 11 offer low wind resistance, allowing them to smoothly draw in low-temperature ambient air. Simultaneously, the high-temperature airflow at their air outlets 102 is directly discharged into the outside environment, creating a stable airflow cycle and minimizing the risk of return air short-circuiting.

[0047] As attached Figure 1 As shown, an air flow baffle 2 is fixedly provided between the opposite sides of any two adjacent outer dry coolers 11. The air flow baffle 2 is a solar panel, which enables the air flow baffle 2 to play a dual advantage: first, the air flow baffle 2 effectively blocks the high-temperature airflow discharged from the air outlet 102 from flowing back to the air inlet 101 through physical isolation, reduces the return air short-circuit phenomenon, and ensures that the low-temperature airflow flowing into the air inlet 101 can fully participate in heat exchange, thereby improving the cooling efficiency; second, the air flow baffle 2 is a solar panel, which can not only utilize the heat insulation characteristics of the solar panel to enhance the thermal barrier performance of the air flow baffle 2, but also convert the originally wasted heat radiation into usable electrical energy through photoelectric conversion, realize energy recycling, and eliminate the energy consumption caused by raising the dry cooler 1, thereby effectively reducing energy consumption.

[0048] In summary, the present invention can improve the cooling efficiency through heat insulation and effectively reduce energy consumption through energy recycling by adding a solar panel between two adjacent outer dry coolers 11, thereby reducing energy consumption while improving cooling efficiency.

[0049] As a preferred embodiment, the matrix structure further includes a central array located at the center of the annular array, and the dry cooler 1 further includes internal dry coolers 12 distributed along the central array. In other words, all internal dry coolers 12 are arranged in a matrix arrangement, and all internal dry coolers 12 are completely surrounded by the external dry cooler 1. Considering that the high-temperature airflow of the internal dry coolers 12 is trapped in the annular array, it is easy to cause return air short circuit due to local vortex. Based on this problem, a spray assembly 3 is fixed between the opposite sides of any two adjacent internal dry coolers 12, as shown in the attached figure. Figure 2 As shown, the spray component 3 forms a wet film by spraying, and directly contacts with the high-temperature airflow for heat exchange, thereby reducing the thermal buoyancy effect caused by the temperature difference, and suppressing the tendency of the high-temperature airflow to flow back to the air inlet 101, effectively reducing the risk of return air short-circuit, optimizing the airflow organization, and further improving the cooling efficiency.

[0050] The key is that the air flow baffle 2 is connected to the spray assembly 3. The air flow baffle 2 acts as a solar panel. While playing the traditional heat insulation function, it converts the incident solar energy into electrical energy through the photovoltaic effect, directly powering the spray assembly 3, forming a self-sufficient energy circulation system, simplifying the structure of the entire system, and eliminating the need for additional energy-consuming equipment, which can significantly reduce energy consumption.

[0051] As a preferred embodiment, as shown in the attached Figure 1 As shown, the airflow baffle 2 includes a first baffle 21 and a second baffle 22, respectively, located on opposite sides of any two adjacent outer dry coolers 11. The first and second baffles 21 and 22 are arranged in a V-shape, with a diversion gap 23 formed between them. A water collection trough 4 is fixed to the bottom opposite sides of any two adjacent outer dry coolers 11. During rainfall, the first and second baffles 21 and 22 first guide rainwater downward, avoiding backflow risks. The diversion gap 23 then directs the water into the water collection trough 4, thereby centrally collecting the rainwater. Rainwater collection offers two advantages: first, the collected rainwater can directly provide water for the spray assembly 3, achieving water recycling, conserving water resources and reducing system operating costs. Second, when the low-temperature airflow passes through the air inlet 101, it undergoes heat exchange with the rainwater in the water collection trough 4. This lowers the temperature of the low-temperature airflow, allowing it to exchange heat more efficiently within the dry cooler 1, thereby improving cooling efficiency.

[0052] As a preferred embodiment, as shown in the attached Figure 1 As shown, dry cooler 1 includes an outer frame 13, which includes a bottom frame 131 whose sides are fixedly connected to water sump 4. To prevent water sump 4 from being higher than bottom frame 131, a drain valve is provided at one end of water sump 4, thereby ensuring that water sump 4 is positioned below air inlet 101. When the drain valve is opened, excess rainwater in water sump 4 is drained to the outside environment, preventing rainwater in water sump 4 from flowing back into the dry cooler through air inlet 101. This prevents rainwater from adhering to the surface of the dry cooler's fins, forming a water film that would hinder the heat exchange efficiency between the low-temperature airflow and the fins, thereby ensuring stable and reliable operation of dry cooler 1.

[0053] The refrigeration system further includes a water level detection member fixedly mounted on the outer frame 13. The water level detection member is used to detect the current liquid level in the water collection tank 4. Specifically, it can be a liquid level sensor. The water level detection member and the drainage pump are both connected to the controller.

[0054] When the controller receives feedback from the water level detector regarding the current liquid level, it determines whether the current liquid level is higher than the side height of the bottom frame 131. If so, the drain valve is activated; otherwise, the drain valve remains closed. The present invention monitors the liquid level in the water sump 4 and automatically adjusts the open and closed state of the drain valve, achieving automatic drainage with a high degree of automation, ensuring continuous and efficient operation of the dry cooler 1, thereby improving cooling efficiency.

[0055] As a preferred embodiment, as shown in the attached Figure 1As shown, the outer frame 13 includes a side frame 132, which is perpendicular to at least one side of the bottom frame 131. A heat exchange tube bundle arranged in a V-shape is provided in the outer frame 13. Support rods are provided between the first partition 21 and the corresponding side frame 132, and between the second partition 22 and the corresponding side frame 132. The support rods reliably support the first partition 21 and the second partition 22, so that the first partition 21 and the second partition 22 form a stable spatial truss structure, optimize the distribution of support points, enable the first partition 21 and the second partition 22 to withstand greater wind loads or ice and snow loads in extreme environments, improve the bending strength of the first partition 21 and the second partition 22, and extend the service life of the first partition 21 and the second partition 22.

[0056] Taking into account the varying solar altitudes in different regions, the inclination angles of the first and second baffles 21, 22 are designed to be adjustable to maximize sunlight utilization. Specifically, the side frame 132 is provided with a number of adjustment holes, all linearly distributed along the height of the outer frame 13. Both the first and second baffles 21, 22 are equipped with hinged supports on the sides facing the sump 4. One end of a support rod is hingedly connected to the hinged support, and the other end is optionally fixed to one of the adjustment holes via a fixing bolt. Adjusting the fixed position of the support rod end adjusts the inclination angles of the first and second baffles 21, 22.

[0057] As a preferred embodiment, as shown in the attached Figure 2 As shown, the spray assembly 3 includes a first wet film 31 and a second wet film 32, respectively fixed on opposite sides of any two adjacent internal dry coolers 12, and a first spray pipe 33 and a second spray pipe 34, respectively, located on opposite sides of any two adjacent internal dry coolers 12. The first spray pipe 33 faces the first wet film 31, and the second spray pipe 34 faces the second wet film 32. The first and second wet films 31 and 32 are arranged in an inverted V-shape, so that the sprayed water flows through the first and second wet films 31 and 32 by gravity. The two wet films exchange heat with the high-temperature airflow discharged from the air outlet 102 of the dry cooler 1. If a return air short circuit occurs, the high-temperature airflow is cooled by the two wet films and then flows back to the air inlet 101 of the dry cooler 1, thereby increasing the heat exchange efficiency of the dry cooler 1 and thus improving the cooling efficiency. Specifically, the first and second wet films 31 and 32 are arranged symmetrically, and the angle between the first wet film 31 and the first spray pipe 33 is equal to the angle between the second wet film 32 and the second spray pipe 34. The first spray pipe 33 and the second spray pipe 34 are both provided with a plurality of spray heads distributed along a linear pattern. The spacing of the spray heads is not specifically limited herein, as long as it ensures that the first wet film 31 and the second wet film 32 can be completely wetted.

[0058] As a preferred embodiment, a swing assembly is provided between the first spray pipe 33 and the connected side frame 132, and between the second spray pipe 34 and the side frame 132. The swing assembly is used to drive the first spray pipe 33 to swing along the length of the first wet film 31, or to drive the second spray pipe 34 to swing along the length of the second wet film 32. By adding the swing assembly, the present invention increases the spraying area of ​​both the first spray pipe 33 and the second spray pipe 34, eliminating the need for a large number of spray pipes and simplifying the structure of the refrigeration system.

[0059] The swing assembly preferably adopts a worm gear design. The worm gear mechanism has high transmission accuracy, which can accurately control the swing angles of the first spray pipe 33 and the second spray pipe 34. Specifically, the swing assembly includes a transmission rod rotatably passed through the side frame 132, a worm wheel fixedly connected to the transmission rod, a worm meshing with the worm wheel, and a drive motor fixedly connected to the worm wheel. The end of the worm wheel away from the transmission rod is fixedly connected to the first spray pipe 33 or the second spray pipe 34. When the drive motor rotates, the worm drives the worm wheel to rotate, so that the worm wheel drives the first spray pipe 33 or the second spray pipe 34 to rotate synchronously through the transmission rod, so that the two spray pipes can swing. The drive motor is fixed to the outer frame 13 to ensure that the drive motor is securely fixed.

[0060] As a preferred embodiment, as shown in the attached Figure 2 As shown, a water storage tank 5 is fixedly provided on the opposite sides of the top of any two adjacent internal dry coolers 12. The water storage tank 5 is used to collect the spray water that is not absorbed by the first wet film 31 and the second wet film 32. The water storage tank is set below the top of the outer frame 13 to ensure that the water storage tank 5 is set below the air outlet 102 of the dry cooler 1 to prevent the water in the water storage tank from flowing into the dry cooler 1. It should also be noted that in addition to the function of storing water, the water storage tank 5 can also serve as a heat insulation component to prevent the high-temperature airflow discharged from the air outlet 102 of the dry cooler 1 from flowing back to the air inlet 101, thereby reducing the risk of return air short-circuiting and enabling the internal dry cooler 12 to improve the cooling efficiency by using both spraying and heat insulation.

[0061] Furthermore, both the first and second spray pipes 33 and 34 are connected to a water supply pipe, which is in turn connected to the water storage tank 5. This water supply pipe is equipped with a water pump, which pumps the accumulated water in the water storage tank 5 into the first and second spray pipes 33 and 34, respectively. This allows the spray water to be recycled, conserving water resources and reducing system operating costs. Furthermore, when the high-temperature airflow is discharged from the air outlet 102, it undergoes heat exchange with the spray water recovered from the water storage tank 5, lowering the discharge temperature of the high-temperature airflow. Even if some of the airflow flows back to the air inlet 101, the negative impact of a return air short circuit is reduced, ensuring more efficient and stable operation of the refrigeration system.

[0062] As a preferred embodiment, the water storage tank 5 is connected to a water supply pipe; the water supply pipe is connected to an external water supply pool, and / or the water supply pipe is connected to the water collecting tank 4; the water supply pipe is provided with a water supply pump; when the water supply pump is started, the water supply pipe draws water from the water supply pool and / or the water collecting tank 4 to replenish the water storage tank 5, ensuring the stable operation of both the first spray pipe 33 and the second spray pipe 34.

[0063] The refrigeration system further comprises a water level detection member, which may be a liquid level sensor, for detecting the actual liquid level of the water storage tank 5. The water replenishment pump and the water level detection member are both connected to the controller.

[0064] When the controller receives feedback from the water level detector regarding the actual liquid level, it determines whether the actual liquid level is lower than the set level. If so, indicating that the liquid level in the water tank 5 is too low, the controller activates the water replenishment pump; if not, the water replenishment pump remains off. The present invention automatically adjusts the on / off state of the water replenishment pump by monitoring the liquid level in the water tank 5 in real time, achieving automatic water replenishment with a high degree of automation, effectively improving the operating stability of the spray assembly 3.

[0065] When the controller receives feedback from the water level detector regarding the actual liquid level, it determines whether the actual liquid level is higher than a specified level. If so, indicating that the liquid level in the water tank 5 is too high, the controller increases the speed of the water supply pump, thereby increasing the spraying speed of the two spray pipes to prevent the water tank 5 from flooding the two spray pipes and affecting their stable operation, thereby effectively improving the operational reliability of the two spray pipes. If not, the water supply pump maintains its current speed. The present invention automatically adjusts the speed of the water supply pump by real-time monitoring of the liquid level in the water tank 5, thereby improving the operational stability of the spray assembly 3.

[0066] As a preferred embodiment, the refrigeration system further includes a circulation pump disposed between the water collection tank 4 and the water replenishment tank, an external temperature detection element disposed between the air inlets 101 of two adjacent external dry coolers 11, and an internal temperature detection element disposed between the air inlets 101 of two adjacent internal dry coolers 12. The circulation pump circulates water between the water collection tank 4 and the water replenishment tank, thereby replenishing the water collection tank 4. The external temperature detection element is used to detect the current air inlet temperature at the air inlet 101 of the external dry cooler 11, and the internal temperature detection element is used to detect the actual air inlet temperature at the air inlet 101 of the internal dry cooler 12; both the external temperature detection element and the internal temperature detection element can be temperature sensors. The circulation pump, external temperature detection element, and internal temperature detection element are all connected to a controller.

[0067] When the controller receives the current inlet air temperature feedback from the external temperature detector, it determines whether the current inlet air temperature is higher than the set inlet air temperature. If so, it means that the current inlet air temperature at the air inlet 101 of the external dry cooler 11 is too high. The controller then starts the circulation pump and increases the speed of the circulation pump, increasing the circulation speed between the water collection tank 4 and the water replenishment tank, so that the high-temperature airflow returning to the air inlet 101 can efficiently exchange heat with the water collection tank 4, thereby improving the heat exchange efficiency. If not, the circulation pump remains off. The present invention adjusts the operating state of the circulation pump by real-time monitoring the current inlet air temperature at the air inlet 101 of the external dry cooler 11, achieving automatic adjustment of the circulation speed, thereby achieving both energy conservation and improved cooling efficiency.

[0068] When the controller receives feedback from the internal temperature detector regarding the actual inlet air temperature, it determines whether the actual inlet air temperature is higher than the set inlet air temperature. If so, indicating that the actual inlet air temperature at the air inlet 101 of the internal dry cooler 12 is too high, the controller starts the water supply pump and increases its speed. This increases the spraying speed of the first spray pipe 33 and the second spray pipe 34, thereby reducing the temperature of the first wet film 31 and the second wet film 32, increasing the temperature of the two wet films and the high-temperature airflow returning to the air inlet 101 of the internal dry cooler 12, and reducing the impact of the return air short circuit on the dry cooler 1. If not, the water supply pump remains off. The present invention adjusts the operating state of the water supply pump by real-time monitoring the actual inlet air temperature at the air inlet 101 of the internal dry cooler 12, and automatically improves the cooling efficiency by increasing the spraying speed of the two spray pipes.

[0069] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
