Description

Technical Field

[0001] This utility model relates to the field of condenser technology, specifically a finned air-cooled condenser. Background Technology

[0002] Finned air-cooled condensers increase the heat exchange area through fins and use ambient temperature air as the cooling medium. A fan drives forced air convection to remove the heat released by the refrigerant vapor. As the refrigerant flows inside the condenser, it comes into contact with the fin surface, transferring heat to the fins. The fan or blower then blows air onto the fins, carrying the heat away and gradually cooling the refrigerant vapor until it condenses into a liquid state.

[0003] Although the condenser is equipped with a dust cover, some fine dust can still enter the equipment with the air, causing the internal circuit components to be covered with dust, affecting heat dissipation efficiency. At the same time, dust will also appear on the surface of the fins, further affecting heat dissipation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a finned air-cooled condenser, which prevents dust accumulation and maintains high heat dissipation efficiency by setting the fins inside the channel and allowing them to swing back and forth.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a finned air-cooled condenser, comprising a channel, a finned body, and a substrate, and further comprising:

[0006] A coil is fixed to one side of the substrate, and a fan is also bolted inside the channel. The fin body is rotatably connected to the inner wall of the channel. A storage box is also bolted to one side of the channel. A first pipeline is connected to one side of the storage box, and one end of the first pipeline is connected to the coil. A pump body is connected to the other side of the storage box, and a second pipeline is connected to the outlet end of the pump body.

[0007] A box body is bolted to one side above the channel. One end of the second pipe is connected to the box body. A third pipe is connected to the other side of the box body. An inner pipe is provided through the inside of the fin body. The inner pipe is connected to the third pipe. A fourth pipe is connected to the other end of the inner pipe.

[0008] Power components;

[0009] Transmission components.

[0010] Preferably, the power assembly includes an impeller, a horizontal column, a vertical column, and a turntable. The impeller is rotatably connected to the interior of the housing. The horizontal column is bolted to the impeller and passes through the housing, rotatably connected to the point where it passes through. The other end of the horizontal column is connected to the vertical column via a bevel gear transmission. The vertical column is fixed to the channel via a bearing seat. The turntable is bolted to the top of the vertical column. A drive rod is rotatably connected to the top of the turntable, and a connecting rod is hinged to the end of the drive rod away from the turntable.

[0011] Preferably, the transmission assembly includes a rack and a cross plate. There are two sets of racks, which are respectively bolted to both sides of the cross plate. A rotating column is also bolted to the top of the fin body, and the rotating column passes through the channel and is rotatably connected to the passage. A transmission gear that meshes with the rack is bolted to the top of the rotating column. The other end of the connecting rod is hinged to the cross plate.

[0012] Preferably, a sliding rod is also bolted to the top of the channel, and the sliding rod passes through the horizontal plate and is slidably connected to the inner wall of the passage.

[0013] Preferably, the third pipeline consists of a short pipe, a tee connector, two long pipes, and multiple flexible hoses, and the flexible hoses in the third pipeline are interconnected with the inner pipeline.

[0014] Preferably, the fourth pipeline consists of a section of pipe connecting the coil, a tee joint, two sections of long pipe, and multiple flexible hoses, and the flexible hoses in the fourth pipeline are interconnected with the inner pipeline.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a channel that is not connected to the interior of the condenser. Combined with a pump and a first pipeline, the heat released by the refrigerant vapor is carried away by circulating heat-conducting oil and enters the interior of the fin body. Since the fin body is located inside the channel, air can dissipate heat simply by passing through the channel, eliminating the need for air to enter the equipment itself and preventing dust from entering. Furthermore, the flowing heat-conducting oil drives the impeller to rotate, which in turn drives the turntable to rotate, causing the rack to reciprocate. This, in turn, with the help of the transmission gears, causes the fin body to oscillate back and forth, preventing dust accumulation and improving heat dissipation efficiency.

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.

[0029] Please see Figures 1-10As shown, a finned air-cooled condenser includes a channel 1, finned bodies 11, and a base plate 3. The base plate 3 is made of copper and has a controller mounted on it, which is fixed to the internal electrical components of the device. Specifically, it is a component for refrigerant heat exchange. The condenser also includes a power assembly 15 and a transmission assembly 14. A coil 4, made of copper, is fixed to one side of the base plate 3. A fan 2 is also connected to the inside of the channel 1. Several finned bodies 11 are arranged inside the channel 1 and are rotatably connected to the inner wall of the channel 1. A storage tank 6 is also connected to one side of the channel 1. A first pipe 5 is connected to one side of the storage tank 6, and one end of the first pipe 5 is connected to the coil 4. A pump body 7 is connected to the other side of the storage tank 6. The inlet end of the storage tank 6 and the pump body 7 are connected to each other through a pipe. A second pipe 8 is connected to the outlet end of the pump body 7. A... A box 9 is bolted to the side. One end of the second pipe 8 is connected to the box 9. A third pipe 10 is connected to the other side of the box 9. An inner pipe 12 is installed inside the fin body 11. Both the fin body 11 and the inner pipe 12 are made of copper. The inner pipe 12 is connected to the third pipe 10. The third pipe 10 consists of a short pipe, a tee connector, two long pipes, and multiple flexible hoses. The flexible hoses in the third pipe 10 are connected to the inner pipe 12. A fourth pipe 13 is connected to the other end of the inner pipe 12. The fourth pipe 13 consists of a pipe connected to the coil 4, a tee connector, two long pipes, and multiple flexible hoses. The flexible hoses in the fourth pipe 13 are connected to the inner pipe 12. In this way, the coil 4, the first pipe 5, the storage box 6, the pump body 7, the second pipe 8, the box 9, the third pipe 10, the inner pipe 12, and the fourth pipe 13 form a circulation structure.

[0030] It should be noted that the condenser is installed within the inverter, forming a cooling system. The core architecture of this system consists of three main components: a pressure transmitter, a controller, and a fan motor (i.e., a blower). The pressure transmitter is precisely installed at key monitoring points on the air-cooled finned condenser, responsible for capturing real-time dynamic changes in the condenser's internal pressure and efficiently converting this pressure information into a 0-10 volt DC voltage signal for output. The controller acts as the information processing center, receiving the voltage signal from the pressure transmitter and using advanced algorithms to perform in-depth analysis and processing of the signal. Based on a preset precise control strategy, the controller can generate a matching control signal, which is also presented in the form of a DC voltage of 0 to 10 volts. The fan motor (fan) acts as the actuator. After receiving the voltage signal from the controller, it can intelligently adjust its rotation speed according to the specific voltage value, thereby flexibly controlling the ventilation volume of the air-cooled finned condenser and realizing the system's efficient regulation of the condenser's operating status. The pressure transmitter is closely connected to the controller's analog input port via a shielded cable. This connection method is like building a "high-speed and safe" transmission channel for the voltage signal, which can effectively shield external electromagnetic interference and ensure the stability and accuracy of the voltage signal during transmission. This allows every minute pressure change to be accurately transmitted to the controller. The controller, in turn, establishes a reliable connection with the control input terminal of the EC motor through a dedicated control cable, which is like laying a "dedicated track" for the control signal. This ensures that the control signal issued by the controller can be accurately and losslessly transmitted to the fan, realizing precise control of the fan's operating status.

[0031] The power assembly 15 includes an impeller 151, a horizontal column 152, a vertical column 153, and a turntable 154. The impeller 151 is rotatably connected to the inside of the housing 9. The horizontal column 152 is bolted to the impeller 151 and passes through the housing 9, rotatably connected to it at the point of penetration. The other end of the horizontal column 152 is connected to the vertical column 153 via a bevel gear transmission. The vertical column 153 is fixed to the channel 1 via a bearing seat, allowing the vertical column 153 to rotate. The turntable 154 is bolted to the top of the vertical column 153. A drive rod 155 is rotatably connected to the top of the turntable 154. The end of the drive rod 155 away from the turntable 154 is hinged to a connecting rod. The rod 156 and the transmission assembly 14 include a rack 141 and a cross plate 142. There are two sets of racks 141, which are respectively bolted to both sides of the cross plate 142. A slide rod 143 is also bolted to the top of the channel 1, and the slide rod 143 passes through the cross plate 142 and is slidably connected to the inner wall of its passage, which allows the cross plate 142 to slide along the surface of the slide rod 143. A rotating column 144 is also bolted to the top of the fin body 11, and the rotating column 144 passes through the channel 1 and is rotatably connected to its passage. A transmission gear 145 that meshes with the rack 141 is bolted to the top of the rotating column 144. The other end of the connecting rod 156 is hinged to the cross plate 142.

[0032] Before operation, the storage tank 6 is filled with heat transfer oil, ensuring that the coil 4, fourth pipe 13, inner pipe 12, third pipe 10, box 9, second pipe 8, and first pipe 5 all contain heat transfer oil. In actual use, channel 1 extends from the outside of the equipment to its interior, while its other end extends to the outside of the equipment on the other side, without directly connecting to the interior. Thus, external air only passes through channel 1 and does not enter the equipment for heat dissipation. During operation, pump 7 and fan 2 are turned on. The activation of pump 7 allows the heat transfer oil inside the pipes to pass through the storage tank 6, second pipe 8, and first pipe 5. Pipe 8, box 9, third pipe 10, inner pipe 12, fourth pipe 13, coil 4 and first pipe 5 flow back to the inside of storage box 6. The heat generated by the refrigerant is transferred to the substrate 3 and absorbed and carried away by the heat transfer oil circulating inside the coil 4. At the same time, the fan 2 blows towards the surface of the fin body 11 inside the channel 1. When the heat transfer oil passes through the inner pipe 12, it transfers heat to the fin body 11 and is carried away by the air flow generated by the fan 2. The air enters from one end of the channel 1 and exits from the other end, without needing to enter the inside of the equipment for heat dissipation, thus preventing dust from entering the inside of the equipment.

[0033] Simultaneously, as the heat transfer oil passes through the interior of the housing 9, it drives the impeller 151 to rotate. The impeller 151 then drives the horizontal column 152 to rotate, which in turn drives the vertical column 153 and the turntable 154 to rotate via the bevel gear. This causes one end of the drive rod 155 to rotate in a circular motion, while the other end of the drive rod 155 drives the horizontal plate 142 to move via the connecting rod 156. This causes the horizontal plate 142 to reciprocate on the surface of the slide bar 143, and causes the rack 141 to reciprocate back and forth. This causes the transmission gear 145 to alternately rotate in both directions, making the fin body 11 swing repeatedly, shaking off the dust on the surface and preventing dust from covering the fin surface and affecting the heat dissipation efficiency. Moreover, the repeatedly swinging fin body 11 can also receive air evenly, increasing the heat exchange area and further improving the heat dissipation effect. In addition, in the prior art, the pressure transmitter is also equipped with a monitoring device. When the pressure transmitter detects an upward trend in the pressure inside the condenser, it generates a corresponding voltage signal with an increasing value and outputs it. Upon receiving this increased voltage signal, the controller initiates its internal processing logic and then outputs a correspondingly stronger voltage control signal to the fan motor. Receiving this enhanced voltage signal, the fan motor increases its operating speed, thereby increasing airflow and enhancing the condenser's heat dissipation efficiency. This ultimately helps the condenser's internal pressure return to its normal range. Conversely, if the pressure transmitter detects a decrease in condenser pressure, its output voltage signal will also decrease. Upon receiving this decreased voltage signal, the controller analyzes the signal and outputs a correspondingly weaker voltage control signal to the fan motor. Upon receiving this weakened signal, the fan motor reduces its operating speed and ventilation volume to stabilize the internal pressure of the condenser. The pressure transmitter monitors the pressure in real time and converts it into a voltage signal, which the controller uses to precisely adjust the fan speed, thereby accurately regulating the condenser ventilation volume to meet the heat dissipation needs of various operating conditions and improve heat dissipation efficiency. The fan speed is adjusted according to the actual pressure requirements, avoiding the energy consumption problems of traditional methods where the fan often runs at high speed or frequently starts and stops, effectively reducing energy consumption. The system can quickly respond to pressure changes and adjust the fan speed in a timely manner to maintain stable condenser pressure, reduce the impact of pressure fluctuations on the system, and enhance system stability and reliability.
