Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigeration technology, specifically a dry and wet separation integrated refrigeration device. Background Technology
[0002] In a refrigeration system, the final heat dissipation stage involves releasing heat into the air; this type of equipment is called a cold source. Currently, commonly used cold sources are cooling towers or dry coolers. Cooling towers rely on evaporative cooling, offering advantages such as low initial investment and the ability to provide lower liquid supply temperatures. Dry coolers, on the other hand, use forced convection heat transfer for cooling, offering advantages such as no water spraying, easy maintenance, and water and energy savings.
[0003] However, both types of cold sources have their own drawbacks in actual use. Cooling towers consume a lot of water throughout the year because they use evaporative cooling, and the heat exchangers are in a humid environment all year round, which makes them prone to scaling and other problems, and maintenance is relatively complicated. The problem with dry coolers is that when the temperature is high in summer, they often require high energy consumption to meet the liquid supply requirements of the system, and when the temperature is too high, they may not even be able to meet the requirements. Utility Model Content
[0004] In order to solve the problems in related technologies, this utility model provides a dry and wet separation integrated refrigeration device, which solves the problems of high water consumption and inability to meet the refrigeration needs when the temperature is too high.
[0005] To solve the above problems, the following technical solutions are provided:
[0006] This utility model discloses an integrated dry and wet separation refrigeration device, including a dry cooler. A cooling tower is connected to one side of the dry cooler. The dry cooler contains a first coil arranged at an angle, with a first water inlet pipe and a first drain pipe connected to the first coil. Both the first water inlet pipe and the first drain pipe are located near the cooling tower. A first cooling coil is installed inside the cooling tower. A first water inlet pipe is connected to the upper end of the first cooling coil, and a first water outlet pipe is connected to the lower end of the first cooling coil. The first water inlet pipe is connected to the first drain pipe. An inlet pipe for introducing the medium to be cooled is connected to the lower end of the first water outlet pipe, and an outlet pipe for discharging the medium to be cooled is connected to the first water outlet pipe. A spray mechanism is installed above the first cooling coil. Air outlets are provided at the top of both the dry cooler and the cooling tower, and fans are installed inside the air outlets.
[0007] In the above scheme, by setting up the first coil and the first cooling coil, the medium to be cooled is introduced from the inlet pipe and flows into the first water pipe from bottom to top, so that the medium to be cooled is introduced into the first coil. The first coil is arranged at an angle to optimize the flow path of the medium to be cooled, reduce the residence time of the medium in the coil, and increase the contact area with air to improve the heat exchange efficiency. This improves the pre-cooling effect of the dry cooler on the medium to be cooled and reduces the load on the subsequent cooling tower.
[0008] The medium to be cooled is first pre-cooled by a dry cooler before entering the cooling tower where it is cooled by evaporative spraying of water. This combines the forced convection of the dry cooler with the evaporative cooling of the cooling tower. In low-temperature environments, heat dissipation relies solely on the dry cooler, eliminating the need to activate the spray system. In high-temperature environments, the dry cooler pre-cools the medium before activating the spray system for further heat exchange, thus avoiding the problems of insufficient efficiency of the dry cooler at high temperatures or excessive water consumption in the cooling tower. This integrated refrigeration unit can flexibly adjust the cooling mode under different temperature conditions.
[0009] The dry cooler also includes a second coil arranged at an angle, the first coil and the second coil are arranged in a V shape, the second coil is connected to a second water inlet pipe and a second drain pipe, and the second water inlet pipe is connected to an inlet pipe.
[0010] In the above scheme, by setting up the second coil, the medium to be cooled enters the first coil and the second coil at the same time, forming a split cooling. The first coil and the second coil are arranged in a V shape, forming an angled structure. Compared with a single coil, the heat exchange area in the dry cooler is significantly increased, making the heat exchange between the medium to be cooled and the air more complete. Moreover, the V-shaped structure can guide the air to flow evenly along the surface of the coil, reducing airflow dead zones and further improving the heat dissipation effect of forced convection.
[0011] The cooling tower is equipped with a second cooling coil. The upper end of the second cooling coil is connected to a second water inlet pipe, and the lower end of the second cooling coil is connected to a second water outlet pipe. The second water inlet pipe is connected to a second drainage pipe, and the second water outlet pipe is connected to an outlet pipe. The first cooling coil and the second cooling coil are arranged in parallel and side by side, and the second cooling coil is located below the spraying mechanism.
[0012] In the above scheme, by setting up a second cooling coil, the spray water can spray the first cooling coil and the second cooling coil at the same time, which improves the evaporative heat dissipation efficiency and cools the medium to be cooled a second time through evaporative cooling; and it increases the cooling capacity of the cooling tower, so that it can maintain a stable liquid supply temperature in high temperature environment.
[0013] An air inlet grille is provided on the outer wall of the cooling tower located below the first cooling coil; a water collection tank is provided at the bottom of the cooling tower, and the water collection tank is connected to a water supply pipe and a sewage discharge pipe, and a valve is provided on the end of the sewage discharge pipe near the water collection tank.
[0014] In the above scheme, by setting up an air inlet grille, the fan is turned on, and outside air rushes into the tower body through the air inlet grille, passes through the surface of the first and second cooling coils, exchanges heat with the spray water and the medium to be cooled, and is discharged from the top air outlet, ensuring the uniformity of air convection in the cooling tower and improving the evaporative cooling efficiency.
[0015] The water collection tank is used to collect the spray water after heat exchange, the water supply pipe is used to replenish the water lost due to evaporation and maintain a stable water level, and the sewage pipe is used to periodically discharge the sediment or sewage in the water collection tank.
[0016] The spraying mechanism includes a spraying water pump and multiple spraying pipes arranged in parallel. The inlet of the spraying water pump is connected to the outlet of the water collection tank. The outlet of the spraying water pump is connected to a vertical pipe. The upper end of the vertical pipe is connected to the spraying pipe. Each spraying pipe is equipped with several spray heads for spraying.
[0017] In the above scheme, by setting up a spraying mechanism, the spraying water pump is turned on, and the spraying head sprays the spraying water evenly on the surface of the first cooling coil and the second cooling coil, increasing the evaporation area; the spraying water pump draws water from the water collection tank, and the sprayed water flows back to the water collection tank, forming a closed loop, which is conducive to saving water resources.
[0018] The upper ends of the first water supply pipe, the first drainage pipe, the second water supply pipe, and the second drainage pipe are all equipped with air vents.
[0019] The above scheme uses an exhaust valve to promptly remove air or steam generated during the flow of the medium to be cooled. If there is gas in the pipeline, it will create air resistance, leading to unstable flow of the medium to be cooled and reduced heat exchange efficiency. The exhaust valve can ensure smooth flow of the medium in the pipeline.
[0020] The above solution has the following advantages:
[0021] 1. This utility model's integrated dry-wet separation refrigeration device, through the arrangement of a first coil and a first cooling coil, allows the medium to be cooled to flow into the inlet pipe. The medium flows from bottom to top into the first water pipe, ensuring that the medium is evenly distributed throughout the first coil. The first coil is arranged at an angle, optimizing the flow path of the medium, reducing its residence time within the coil, and increasing the contact area with air to improve heat exchange efficiency. This enhances the pre-cooling effect of the dry cooler on the medium and reduces the load on the subsequent cooling tower. The medium is pre-cooled by the dry cooler before entering the cooling tower for evaporative cooling via spray water, combining the forced convection of the dry cooler and the evaporative cooling of the cooling tower. In low-temperature environments, heat dissipation relies solely on the dry cooler, eliminating the need to activate the spray mechanism. In high-temperature environments, the dry cooler pre-cools the medium before activating the spray mechanism for further heat exchange, thus avoiding insufficient efficiency of the dry cooler at high temperatures or excessive water consumption in the cooling tower. This integrated refrigeration device allows for flexible adjustment of the cooling mode under different temperature conditions.
[0022] 2. The dry cooler also contains a second coil arranged at an angle. The medium to be cooled enters the first coil and the second coil at the same time, forming a split cooling. The first coil and the second coil are arranged in a V-shape, forming an angled structure. Compared with a single coil, this significantly increases the heat exchange area inside the dry cooler, making the heat exchange between the medium to be cooled and the air more complete. In addition, the V-shaped structure can guide the air to flow evenly along the surface of the coil, reducing dead air angles and further improving the heat dissipation effect of forced convection.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] In specific embodiment 1, such as Figures 1-5 As shown, the present invention provides a dry and wet separation integrated refrigeration device including a dry cooler 1, a cooling tower 2 connected to one side of the dry cooler 1, a first coil 101 arranged at an incline, a first water pipe 102 and a first drain pipe 103 connected to the first coil 101, both the first water pipe 102 and the first drain pipe 103 being located on the side close to the cooling tower 2; a first cooling coil 201 is provided inside the cooling tower 2, the upper end of the first cooling coil 201 is connected to a first water inlet pipe 202, the lower end of the first cooling coil 201 is connected to a first water outlet pipe 203, the first water inlet pipe 202 and the first drain pipe 103 are connected; the lower end of the first water pipe 102 is connected to an inlet pipe 3 for introducing the medium to be cooled, the first water outlet pipe 203 is connected to an outlet pipe 4 for discharging the medium to be cooled; a spray mechanism is provided above the first cooling coil 201; both the dry cooler 1 and the cooling tower 2 are provided with air outlets, and fans 5 are provided inside the air outlets. The medium to be cooled is introduced into the inlet pipe 3 and flows from bottom to top into the first water pipe 102, so that the medium to be cooled is introduced into the first coil 101. The first coil 101 is arranged at an angle to optimize the flow path of the medium to be cooled, reduce the residence time of the medium in the coil, and increase the contact area with air to improve the heat exchange efficiency, thereby improving the pre-cooling effect of the dry cooler 1 on the medium to be cooled and reducing the load on the subsequent cooling tower 2.
[0034] The medium to be cooled is first pre-cooled by the dry cooler 1, and then enters the cooling tower 2 for evaporative cooling by spray water. This combines the forced convection of the dry cooler 1 with the evaporative cooling of the cooling tower 2. In low-temperature environments, heat dissipation relies solely on the dry cooler 1, without the need to activate the spray mechanism. In high-temperature environments, the dry cooler 1 pre-cools the medium before activating the spray mechanism for further heat exchange, thus avoiding the problems of insufficient efficiency of the dry cooler 1 at high temperatures or excessive water consumption of the cooling tower 2. This integrated refrigeration unit can flexibly adjust the cooling mode under different temperature conditions.
[0035] like Figure 3 As shown, the dry cooler 1 also includes a second coil 104 arranged at an angle. The first coil 101 and the second coil 104 are arranged in a V-shape. A second water inlet pipe 105 and a second drain pipe 106 are connected to the second coil 104. The second water inlet pipe 105 is connected to the inlet pipe 3. The medium to be cooled simultaneously enters the first coil 101 and the second coil 104, forming a split cooling. The first coil 101 and the second coil 104 are arranged in a V-shape, forming an angled structure. Compared with a single coil, this significantly increases the heat exchange area inside the dry cooler 1, making the heat exchange between the medium to be cooled and the air more complete. Moreover, the V-shaped structure can guide the air to flow evenly along the surface of the coil, reducing dead air angles and further improving the heat dissipation effect of forced convection.
[0036] like Figure 4 As shown, a second cooling coil 204 is installed inside the cooling tower 2. The upper end of the second cooling coil 204 is connected to a second water inlet pipe 205, and the lower end of the second cooling coil 204 is connected to a second water outlet pipe 206. The second water inlet pipe 205 is connected to a second drainage pipe 106, and the second water outlet pipe 206 is connected to an outlet pipe 4. The first cooling coil 201 and the second cooling coil 204 are arranged parallel to each other, with the second cooling coil 204 located below the spray mechanism. The spray water can simultaneously spray the first cooling coil 201 and the second cooling coil 204, improving the evaporative heat dissipation efficiency and achieving secondary cooling of the medium to be cooled through evaporative cooling. This also increases the cooling capacity of the cooling tower 2, allowing it to maintain a stable liquid supply temperature even in high-temperature environments.
[0037] like Figure 4As shown, an air inlet grille 6 is provided on the outer wall of the cooling tower 2 located below the first cooling coil 201. When the fan 5 is turned on, outside air rushes into the tower body through the air inlet grille 6, passes through the surfaces of the first cooling coil 201 and the second cooling coil 204, exchanges heat with the spray water and the medium to be cooled, and is discharged from the top air outlet, ensuring the uniformity of air convection inside the cooling tower 2 and improving the evaporative cooling efficiency. A water collection tank 7 is provided at the bottom of the cooling tower 2. The water collection tank 7 is connected to a water supply pipe 8 and a drain pipe 9. A valve 10 is provided on the end of the drain pipe 9 near the water collection tank 7. The water collection tank 7 is used to collect the spray water after heat exchange, the water supply pipe 8 is used to replenish the water lost due to evaporation and maintain a stable water level, and the drain pipe 9 is used to periodically discharge the sediment or sewage in the water collection tank 7.
[0038] The spraying mechanism includes a spray water pump 11 and multiple spray pipes 12 arranged in parallel. The inlet of the spray water pump 11 is connected to the outlet of the water collection tank 7, and the outlet of the spray water pump 11 is connected to a vertical pipe 13. The upper end of the vertical pipe 13 is connected to the spray pipes 12. Each spray pipe 12 is equipped with several spray heads for spraying. When the spray water pump 11 is turned on, the spray heads spray water evenly onto the surfaces of the first cooling coil 201 and the second cooling coil 204, increasing the evaporation area. The spray water pump 11 draws water from the water collection tank 7, and the sprayed water flows back to the water collection tank 7, forming a closed loop, which helps to save water resources.
[0039] In a specific embodiment 2, such as Figure 3 As shown, the difference between this embodiment and embodiment 1 is that the upper ends of the first water pipe 102, the first drainage pipe 103, the second water pipe 105, and the second drainage pipe 106 in this embodiment are all equipped with exhaust valves 14, which are used to promptly discharge the air or steam generated during the flow of the medium to be cooled. If there is gas in the pipe, it will form an air blockage, resulting in unstable flow of the medium to be cooled and reduced heat exchange efficiency. The exhaust valve 14 can ensure the smooth flow of the medium in the pipe.
[0040] The medium to be cooled is introduced into the inlet pipe 3 and flows into the first water pipe 102 and the second water pipe 105 from bottom to top, so that the first coil 101 and the second coil 104 are filled with the medium to be cooled, and the fan 5 is turned on.
[0041] In a low-temperature environment, the air in the external environment exchanges heat with the medium to be cooled in the first coil 101 and the second coil 104, thereby cooling the medium without having to turn on the spray water pump 11.
[0042] In a high-temperature environment, the medium to be cooled in the first coil 101 and the second coil 104 is first pre-cooled by the dry cooler 1. The pre-cooled medium in the first coil 101 flows through the first drain pipe 103 and the first water inlet pipe 202 and flows into the first cooling coil 201. The pre-cooled medium in the second coil 104 flows through the second drain pipe and the second water inlet pipe 205 and flows into the second cooling coil 204. At the same time, the spray water pump 11 is turned on, and the spray head sprays spray water evenly to perform secondary heat exchange on the medium to be cooled in the first cooling coil 201 and the second cooling coil 204. The medium to be cooled after heat exchange flows out from the outlet pipe 4, and the heat-exchanged medium can be obtained.
