Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and in particular to a refrigeration system. Background Technology

[0002] Data centers typically house a large number of high-power electronic devices. When these devices are running continuously, their internal heat-generating components generate a significant amount of heat. This heat exchanges with the air inside and outside the devices. When heat dissipation efficiency is low, the accumulation of heat can cause the internal temperature of the devices to exceed safe thresholds or the ambient temperature to rise abnormally, which can easily lead to malfunctions of the electronic devices.

[0003] Under normal circumstances, the heat exchange tube bundles in the dry cooler are arranged in a V-shape, which has an aerodynamic design flaw. During operation, the exhaust cooling return air does not follow the preset flow channel circulation, but flows directly back to the air inlet, forming a return air short-circuit phenomenon. In this phenomenon, the cooling return air fails to participate in effective heat exchange, which seriously affects the cooling efficiency. At the same time, the densely arranged dry cooler group continuously discharges high-temperature airflow, causing a local heat island effect, reducing the heat exchange temperature difference, and resulting in a decrease in cooling efficiency.

[0004] To address these issues, existing solutions have at least the following problems: raising the dry cooler unit requires hoisting equipment, and installing guide pipes at the air outlet also requires auxiliary fans. Both hoisting equipment and auxiliary fans increase energy consumption, resulting in excessive energy consumption of the entire refrigeration system.

[0005] Therefore, how to reduce energy consumption while improving cooling efficiency is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0030] An airflow baffle is fixed between any two adjacent outer sides of the dry cooler. The airflow baffle is a solar panel, which gives the airflow baffle a dual advantage: First, the airflow baffle effectively blocks the high-temperature airflow discharged from the air outlet from flowing back to the air inlet through physical isolation, reducing the phenomenon of short-circuiting of return air and ensuring that the low-temperature airflow flowing into the air inlet can fully participate in heat exchange, thereby improving cooling efficiency. Second, as a solar panel, the airflow baffle can not only utilize the heat insulation characteristics of the solar panel to enhance the thermal barrier performance of the airflow baffle, but also convert the originally wasted heat radiation into usable electrical energy through photoelectric conversion, realizing energy recovery and utilization, and eliminating the energy consumption caused by raising the dry cooler, thereby effectively reducing energy consumption.

[0031] Therefore, by adding a solar panel between two adjacent outer dry coolers, the present invention can improve cooling efficiency through heat insulation and effectively reduce energy consumption through energy recovery and utilization, thereby achieving energy reduction while improving cooling efficiency.

[0042] 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.

[0043] 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] This invention discloses a refrigeration system, including a plurality of dry coolers 1 arranged in a matrix structure, that is, all dry coolers 1 are arranged in a matrix.

[0045] As attached Figure 1 and 2 As shown, each dryer 1 is equipped with an air inlet 101 and an air outlet 102. The air inlet 101 can be located on the side of the dryer 1, and the air outlet 102 can be located on the top of the dryer 1. Low-temperature airflow from the external environment flows into the dryer 1 through the air inlet 101, exchanges heat with the dryer 1 to form a high-temperature airflow, and finally exits from the air outlet 102. In other words, the airflow pattern of the dryer 1 is horizontal intake and vertical exhaust. Horizontal intake ensures that the low-temperature airflow is evenly distributed along the entire heat exchange surface of the dryer 1, avoiding localized overheating or insufficient cooling. Vertical exhaust creates a chimney effect, causing the high-temperature airflow to rise naturally away from the air inlet 101, reducing short-circuiting of the return air. Each dryer 1's air outlet 102 is equipped with a protective cover to prevent rainwater or dust backflow, making the dryer 1 operate more stably.

[0046] The matrix structure includes an outermost ring array facing the external environment. The dry cooler 1 includes outer dry coolers 11 distributed along the ring array, comprising at least two rings. The air inlet 101 of the outer dry cooler 11 has low air resistance, allowing it to smoothly draw in low-temperature ambient air; at the same time, the high-temperature airflow from its outlet 102 can be directly discharged to the external environment, forming a stable airflow circulation and minimizing the risk of backflow short circuit.

[0047] As attached Figure 1 As shown, an airflow baffle 2 is fixed between any two adjacent outer dry coolers 11 on opposite sides. The airflow baffle 2 is a solar panel, which gives the airflow baffle 2 a dual advantage: First, the airflow 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, reducing the phenomenon of short-circuiting of return air and ensuring that the low-temperature airflow flowing into the air inlet 101 can fully participate in heat exchange and improve cooling efficiency; Second, as a solar panel, the airflow baffle 2 can not only utilize the heat insulation characteristics of the solar panel to enhance the thermal barrier performance of the airflow baffle 2, but also convert the originally wasted heat radiation into usable electrical energy through photoelectric conversion, realizing energy recovery and utilization, and eliminating the energy consumption caused by raising the dry cooler 1, effectively reducing energy consumption.

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

[0049] In a preferred embodiment, the matrix structure further includes a central array located at the center of the annular array, and the dry cooler 1 also includes internal dry coolers 12 distributed along the central array. That is, all internal dry coolers 12 are arranged in a matrix, and all internal dry coolers 12 are completely surrounded by the external dry coolers 1. Considering that the high-temperature airflow of the internal dry coolers 12 is trapped within the annular array, it is prone to backflow short-circuiting due to local eddies. To address 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 diagram. Figure 2 As shown, the spray assembly 3 forms a wet film by spraying, which directly contacts the high-temperature airflow for heat exchange, weakens the thermal buoyancy effect caused by temperature difference, suppresses the tendency of high-temperature airflow to flow back to the air inlet 101, effectively reduces the risk of short-circuiting return air, optimizes airflow organization, and further improves cooling efficiency.

[0050] Crucially, the airflow baffle 2 is connected to the spray assembly 3. As a solar panel, the airflow baffle 2 not only performs the traditional heat insulation function, but also converts the incident solar energy into electrical energy through the photovoltaic effect, directly powering the spray assembly 3 and forming a self-sufficient energy cycle system. This simplifies the structure of the entire system and eliminates the need for additional energy-consuming equipment, thus significantly reducing energy consumption.

[0051] As a preferred embodiment, as shown in the appendix Figure 1 As shown, the airflow baffle 2 includes a first baffle 21 and a second baffle 22 respectively disposed on opposite sides of any two adjacent outer dry coolers 11. The first baffle 21 and the second baffle 22 are arranged in a V-shape, and a guide gap 23 is formed between the first baffle 21 and the second baffle 22. A water collection tank 4 is fixedly provided on opposite sides of the bottom of any two adjacent outer dry coolers 11. During rainfall, the first baffle 21 and the second baffle 22 first guide the rainwater to flow downwards to avoid backflow, and then the water flow is guided to the water collection tank 4 by the guide gap 23, realizing the centralized collection of rainwater. Rainwater collection has dual advantages: on the one hand, the collected rainwater can directly provide water for the spray assembly 3, realizing the recycling of water resources, which saves water resources and reduces the operating cost of the system; on the other hand, when the low-temperature airflow flows through the air inlet 101, it will exchange heat with the rainwater in the water collection tank 4, thereby reducing the temperature of the low-temperature airflow and enabling the low-temperature airflow to exchange heat more efficiently in the dry cooler 1, thereby improving the cooling efficiency.

[0052] As a preferred embodiment, as shown in the appendix Figure 1 As shown, the dry cooler 1 includes an outer frame 13, and the outer frame 13 includes a bottom frame 131 that is fixedly connected to the side of the water collection tank 4. To prevent the water collection tank 4 from being higher than the bottom frame 131, a drain valve is provided at one end of the water collection tank 4, thereby ensuring that the water collection tank 4 is set lower than the air inlet 101. When the drain valve is opened, excess rainwater in the water collection tank 4 is discharged to the outside environment, preventing rainwater in the water collection tank 4 from flowing back into the dryer along the air inlet 101, and preventing rainwater from adhering to the surface of the heat dissipation fins of the dry cooler 1 to form a water film, which would hinder the heat exchange efficiency between the low-temperature airflow and the heat dissipation fins, thus ensuring that the dry cooler 1 operates stably and reliably.

[0053] The refrigeration system also includes a water level detection device fixed to the outer frame 13. The water level detection device is used to detect the current liquid level in the water collection tank 4, and can specifically be a liquid level sensor. Both the water level detection device and the drain valve are connected to the controller.

[0054] When the controller receives the current liquid level height from the water level detection device, it determines whether the current liquid level height is higher than the side height of the bottom frame 131. If so, the drain valve is activated; otherwise, the drain valve remains closed. This invention automatically adjusts the opening and closing state of the drain valve by monitoring the liquid level height of the water collection tank 4, achieving automatic drainage with a high degree of automation. This ensures the continuous and efficient operation of the dry cooler 1, thereby improving refrigeration efficiency.

[0055] As a preferred embodiment, as shown in the appendix Figure 1As shown, the outer frame 13 includes side frames 132, which are perpendicularly disposed on at least one side of the bottom frame 131. A V-shaped heat exchange tube bundle is provided inside the outer frame 13. Support rods are provided between the first partition 21 and its corresponding side frame 132, and between the second partition 22 and its corresponding side frame 132. These support rods reliably support the first partition 21 and the second partition 22, forming a stable spatial truss structure. This optimizes the distribution of support points, enabling the first partition 21 and the second partition 22 to withstand greater wind loads or ice and snow loads in extreme environments, improving their bending strength and extending their service life.

[0056] Considering the differences in solar altitude in different regions, the tilt angles of the first partition 21 and the second partition 22 are set to be adjustable to fully improve the utilization rate of sunlight. Specifically, the side frame 132 is provided with several adjustment holes, all of which are linearly distributed along the height direction of the outer frame 13; both the first partition 21 and the second partition 22 are provided with hinge supports on the side facing the water collection tank 4; one end of the support rod is hinged to the hinge support and the other end is selectively fixed to the adjustment hole by a fixing bolt. By adjusting the fixed position of the end of the support rod, the tilt angles of the first partition 21 and the second partition 22 can be adjusted.

[0057] As a preferred embodiment, as shown in the appendix 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 disposed on opposite sides of any two adjacent internal dry coolers 12. The first spray pipe 33 is opposite to the first wet film 31, and the second spray pipe 34 is opposite to the second wet film 32. The first wet film 31 and the second wet film 32 are arranged in an inverted V shape, so that the sprayed water flow wets the first wet film 31 and the second wet film 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. Once a 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, increasing the heat exchange efficiency of the dry cooler 1, thereby improving the cooling efficiency. Specifically, the first wet film 31 and the second wet film 32 are symmetrically arranged, and the angle between the first wet film 31 and the first spray pipe 33 and the angle between the second wet film 32 and the second spray pipe 34 are equal. The first spray pipe 33 and the second spray pipe 34 are each provided with a number of spray heads distributed in a linear manner. The spacing between the spray heads is not specifically limited here, as long as it can ensure that the first wet film 31 and the second wet film 32 can be completely wetted.

[0058] In 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 direction of the first wet film 31, or to drive the second spray pipe 34 to swing along the length direction of the second wet film 32. By adding the swing assembly, the present invention increases the spray area of ​​both the first spray pipe 33 and the second spray pipe 34, eliminating the need for too many spray pipes and simplifying the structure of the refrigeration system.

[0059] The oscillating assembly preferably employs a worm gear design, which offers high transmission precision, enabling accurate control of the oscillation angles of the first spray pipe 33 and the second spray pipe 34. Specifically, the oscillating assembly includes a transmission rod rotatably passing through the side frame 132, a worm gear fixedly connected to the transmission rod, a worm meshing with the worm gear, and a drive motor fixedly connected to the worm. The end of the worm gear furthest from the transmission rod is fixedly connected to either the first spray pipe 33 or the second spray pipe 34. When the drive motor rotates, the worm drives the worm gear to rotate, causing the worm gear to drive the first spray pipe 33 or the second spray pipe 34 to rotate synchronously via the transmission rod, thus oscillating the two spray pipes. The drive motor is fixed to the outer frame 13, ensuring reliable fixation.

[0060] As a preferred embodiment, as shown in the appendix Figure 2 As shown, water storage tanks 5 are fixedly installed on opposite sides of the top of any two adjacent internal dry coolers 12. The water storage tanks 5 are used to collect spray water that has not been absorbed by the first wet film 31 and the second wet film 32. The water storage tanks are positioned below the top of the outer frame 13 to ensure that the water storage tanks 5 are positioned below the air outlet 102 of the dry cooler 1, preventing water from flowing into the dry cooler 1. It should also be noted that, in addition to its water storage function, the water storage tanks 5 can also serve as insulation, preventing the high-temperature airflow discharged from the air outlet 102 of the dry cooler 1 from flowing back to the air inlet 101, reducing the risk of short-circuiting the return air, and allowing the internal dry cooler 12 to improve cooling efficiency through both spraying and insulation methods.

[0061] Furthermore, both the first spray pipe 33 and the second spray pipe 34 are connected to a water supply pipe, which is connected to a water storage tank 5. The water supply pipe is equipped with a water pump, which draws the accumulated water in the water storage tank 5 to the first spray pipe 33 and the second spray pipe 34 respectively, enabling the spray water to be recycled and reused. This saves water resources and reduces the system's operating costs. In addition, when high-temperature airflow is discharged from the air outlet 102, the high-temperature airflow exchanges heat with the recycled spray water in the water storage tank 5, reducing the discharge temperature of the high-temperature airflow. Even if some airflow flows back to the air inlet 101, it reduces the negative impact of short-circuiting the return air, ensuring more efficient and stable operation of the refrigeration system.

[0062] In a preferred embodiment, the water storage tank 5 is connected to a water supply pipe; the water supply pipe is connected to a water supply pool, and / or the water supply pipe is connected to a water collection tank 4; the water supply pipe is equipped 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 collection tank 4 to supply water to 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 also includes a water level detection device, specifically a water level sensor, for detecting the actual liquid level in the water storage tank 5. Both the water replenishment pump and the water level detection device are connected to the controller.

[0064] When the controller receives the actual water level height from the water level detection device, it determines whether the actual water level is lower than the set water level height. If so, it means the water level in the water tank 5 is too low, and the water replenishment pump is activated; otherwise, the water replenishment pump remains off. This invention automatically adjusts the activation and deactivation of the water replenishment pump by monitoring the water level in the water tank 5 in real time, achieving automatic water replenishment with a high degree of automation, effectively improving the working stability of the spray assembly 3.

[0065] When the controller receives the actual liquid level height from the water level detection device, it determines whether the actual liquid level height is higher than the specified liquid level height. If so, it means the liquid level in the water tank 5 is too high, so the controller increases the speed of the water supply pump to increase the spraying speed of the two spray pipes, preventing the water tank 5 from submerging the two spray pipes and affecting their stable operation, thus effectively improving the working reliability of the two spray pipes. If not, the water supply pump maintains its current speed. This invention automatically adjusts the speed of the water supply pump by monitoring the liquid level height in the water tank 5 in real time, thereby improving the working stability of the spray assembly 3.

[0066] In a preferred embodiment, the refrigeration system further includes a circulation pump located between the water collection tank 4 and the water replenishment tank, an outer temperature sensor located between the air inlets 101 of two adjacent outer dry coolers 11, and an inner temperature sensor located between the air inlets 101 of two adjacent inner dry coolers 12. The circulation pump circulates water between the water collection tank 4 and the water replenishment tank, replenishing the water collection tank 4. The outer temperature sensor detects the current air inlet temperature of the air inlet 101 of the outer dry cooler 11, while the inner temperature sensor detects the actual air inlet temperature of the air inlet 101 of the inner dry cooler 12; both the outer and inner temperature sensors can be temperature sensors. The circulation pump, the outer temperature sensor, and the inner temperature sensor are all connected to a controller.

[0067] When the controller receives the current inlet air temperature from the external temperature sensor, 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 its speed to increase the circulation speed between the water collection tank 4 and the makeup water tank, allowing the high-temperature airflow returning to the air inlet 101 to efficiently exchange heat with the water collection tank 4, thus improving heat exchange efficiency. If not, the circulation pump remains off. This invention adjusts the operating state of the circulation pump by real-time monitoring of the current inlet air temperature at the air inlet 101 of the external dry cooler 11, achieving automatic adjustment of the circulation speed, which not only saves energy but also improves cooling efficiency.

[0068] When the controller receives the actual inlet air temperature from the internal temperature sensor, it determines whether the actual inlet air temperature is higher than the set inlet air temperature. If so, it means that the actual inlet air temperature at the air inlet 101 of the internal dry cooler 12 is too high. The controller then starts the water pump and increases its speed. By increasing the spray speed of the first spray pipe 33 and the second spray pipe 34, the temperature of the first wet film 31 and the second wet film 32 is reduced, 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, thus reducing the impact of the return air short circuit on the dry cooler 1. If not, the water pump remains off. This invention adjusts the operating state of the water pump by real-time monitoring of 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 spray speed of the two spray pipes.
