Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a condenser cleaning system and a condenser. Background Art

[0002] The air conditioning system is an important component of the computer room in various industries to ensure the normal operation of the equipment. As the integration of equipment becomes higher and higher, the heat generated by the equipment is also increasing. The burden of the air conditioning system increases sharply, and the energy consumption surges. In addition, since the air conditioning system needs to be in a high-load working state for a long time, it seriously affects its lifespan, and components are frequently damaged, which greatly increases the operating costs. Therefore, in order to reduce energy consumption and reduce the loss of air conditioning components, exploring the problems and effective solutions has become an important research topic.

[0003] The condenser is the main component that quickly completes heat exchange between the high-temperature and high-pressure gas compressed by the air-conditioning compressor in the air-conditioning system and the outside. In order to improve the heat dissipation effect, the heat dissipation area should be increased as much as possible. Therefore, the heat dissipation fins on the condenser are ultra-thin and densely arranged. However, in areas with a lot of dust and flying catkins, dust and flying catkins can easily be blocked between the heat dissipation fins, hindering air circulation and seriously affecting heat dissipation. The indoor temperature cannot reach the expected temperature, and the air conditioner needs to run continuously, which not only consumes and wastes a lot of electricity, but also fails to achieve a cooling effect, resulting in high temperature in the computer room, causing the equipment operating temperature to rise, failures or even burning.

[0004] At present, the condenser is treated by manual flushing, setting up awnings, micro-water spraying, etc., but these treatment methods all have certain defects:

[0005] Manual flushing requires workers to work directly in a high temperature and exposed environment. Due to the large number of equipment, long-term work is more harmful to the human body. High temperature alarms often occur at night, requiring workers to work at night. Due to unclear vision, it is easy to get into danger. Manual flushing can often only be carried out at special locations, which is difficult to fully cover and more likely to cause a waste of water resources. High-pressure water guns are usually used, and incorrect spray angles can easily cause the heat sink fins to twist and unevenly arrange.

[0006] Although setting up a sunshade for the condenser can reduce the high temperature caused by direct sunlight to a certain extent, it cannot reduce the high temperature caused by the ambient temperature, nor can it play a cleaning role.

[0007] The condenser is sprayed with micro-water, and the spraying position is relatively fixed. Similar to manual cleaning, it usually requires manual control and lacks intelligence. There are still problems such as water waste, insufficient flushing range and intensity, etc. Utility Model Content

[0072] Reference Figures 1 to 4 In some related technologies, the condenser includes: a cavity 11, a fan 13 and heat dissipation fins 11. The fan 13 and the heat dissipation fins 11 work together to enable the condenser to effectively dissipate heat. During operation, the fan 13 generates strong wind in the cavity 11 to blow hot air away from the heat dissipation fins 11, thereby accelerating the transfer and dissipation of heat. The heat dissipation fins have a large-area thin-sheet structure, forming a plurality of small gaps and a large surface area, thereby increasing the area in contact with the air and improving the heat transfer efficiency.

[0073] However, in areas with a lot of dust and flying catkins, dust and flying catkins can easily get stuck between the heat sink fins, hindering air circulation and seriously affecting heat dissipation. Therefore, a solution that can effectively clean the heat sink fins 11 is urgently needed.

[0074] Reference Figure 1 In a first aspect, an embodiment of the utility model provides a condenser cleaning system, which is fixed between a fan 13 and a heat dissipation fin 11 in a cavity 11 of the condenser, and the system comprises:

[0075] A temperature sensor 2, the temperature sensor 2 is fixedly connected to the heat dissipation fins 11 of the condenser, and is used to detect the temperature and generate temperature data;

[0077] A cleaning device, the cleaning device is electrically connected to the control unit 3, and is used to receive the control instruction, and adjust the cleaning position and cleaning angle of the heat dissipation fins 11 according to the control instruction.

[0078] In the embodiment of the present disclosure, the temperature sensor 2 detects the temperature of the heat sink fins 11 of the condenser, and the temperature sensor 2 sends the temperature data to the control unit 3.

The cleaning device adjusts the water outlet position and water outlet angle according to the control instruction, thereby adjusting the cleaning position and cleaning angle of the heat sink fins 11, and can effectively clean the heat sink fins 11 comprehensively to avoid cleaning blind spots. The cleaning system of the condenser has the advantages of automation, intelligence, humanization, flexible control, resource conservation, and rational use of natural energy.

[0079] In some embodiments, the working parameters of the control unit 3 are configured by the IoT control center 7, and the IoT control center 7 is connected to the control unit 3 via the network 8. The IoT control center 7 is used to manage the control unit 3, create a subscription topic and a publishing topic for the control unit 3, wherein the subscription topic refers to receiving the temperature feedback of the temperature sensor 2, and the publishing topic refers to sending a control command and setting the mode switching type (where the default automatic mode). In some embodiments, the IoT control center 7 can also display the received temperature data in text or visual form, so that relevant personnel can understand the temperature state of the heat dissipation fins 11 of the condenser in real time through the IoT control center 7, thereby configuring or adjusting various working parameters of the cleaning device and the control unit 3. The system can be either centrally controlled or independently operated, and the temperature state of each condenser can be monitored at any time through the IoT control center 7 to start the system.

[0080] The disclosed embodiment does not impose any special restrictions on the working parameters, and the temperature threshold, flushing intensity, flushing speed, mode switching type (manual or automatic), flushing interval, flushing frequency, etc. can be set according to actual needs to achieve flexible control of the cleaning device by the control unit 2. Among them, the network is used for communication between the IoT control center 7 and the control unit 3, and can be a wired network or a wireless network access method to control the connection between the IoT control center 7 and the control unit 3.

[0081] In some embodiments, when the working parameters include a mode switching type, the cleaning system of the condenser can be set to an automatic mode or a manual mode; in the automatic mode, the system is completely automatically operated by the working parameters of the Internet of Things control center 7; in the manual mode, the staff controls the control unit 3 through the Internet of Things control center 7 to realize manual control operation of the cleaning device.

[0082] Reference Figures 1 to 4 In some embodiments, the cleaning device comprises:

[0083] A supporting crossbeam 41, wherein a first end of the supporting crossbeam 41 is fixedly connected to a first surface of the cavity 12 of the condenser, and a second end of the supporting crossbeam 41 is fixedly connected to a second surface of the cavity 12;

[0084] A rotating arm 42, wherein a first end of the rotating arm 42 is rotatably connected to the supporting beam 41;

[0085] A transmission unit, wherein a first end of the transmission unit is fixedly connected to a first end of the rotating arm 42, and a second end of the transmission unit is electrically connected to the control unit 3; the transmission unit is used to control the second end of the rotating arm 42 to reciprocate in an arc shape with the first end of the rotating arm 42 as the center according to the control instruction;

[0086] A water supply unit is installed on the rotating arm 42 .

[0087] In an embodiment of the present disclosure, the cleaning device includes a support beam 41, a rotating arm 42, a transmission unit, and a water supply unit, wherein the support beam 41 is used to provide a support structure of the cleaning system in the cavity 11 of the condenser. The first end of the rotating arm 42 is rotatably connected to the support beam 41, so that under the operation of the transmission unit, the entire rotating arm 42 can be driven to realize a circular arc reciprocating rotation with the first end of the rotating arm 42 as the center. At the same time, a water supply unit is provided on the rotating arm 42, and the water supply unit can adjust the water output and the water output angle according to the control instructions of the control unit 3.

[0088] It is worth noting that, since the condenser of the industrial air conditioner usually has a larger cavity 11 structure, the first end of the support beam 41 in the embodiment of the present disclosure is fixedly connected to the first surface of the cavity 12 of the condenser, and the second end is fixedly connected to the second surface of the cavity 12, and the second end of the rotating arm 42 reciprocates in the cavity 11 in an arc shape with the first end of the rotating arm 42 as the center. Therefore, the maximum cleaning coverage can be achieved by the rotating arm 42 having a length less than or equal to half the length of the cavity 11. Compared with the structure and assembly method of the track-type mechanical device in some related technologies, the system has lower material cost and low complexity, which is conducive to later maintenance.

[0089] Reference Figures 1 to 5In some embodiments, the water supply unit is rotatably connected to the rotating arm 42 so that the angle between the water supply unit and the heat dissipation fins 11 can be adjusted.

[0090] In the embodiment of the present disclosure, since the cooling fins 11 are arranged on one side of the cavity 12, the angle between the straight line formed by the first end and the second end of the rotating arm 42 and the surface of the cooling fins 11 in the cavity 12 is less than 90°, and the water supply unit is fixed on the rotating arm 42. The water outlet angle of the water supply unit is perpendicular to the cooling fins 11, and the cooling fins 11 are cleaned by the outlet water. However, since the water supply unit is rotatably connected to the rotating arm 42, that is, the water supply unit can rotate along the straight line formed by the first end and the second end of the rotating arm 42 as the center, the cleaning angle can be adjusted, thereby solving the problem of a flushing blind spot caused by the large spacing between the water outlet ends of the water supply unit.

[0091] Reference Figure 5 In some embodiments, the cleaning device further comprises:

[0092] The limit sensor 45 is arranged on the inner wall of the cavity 12 of the condenser, and is used to send a steering signal to the control unit 3 when it detects that the rotating arm 42 abuts against the limit sensor, so that the control unit 3 controls the rotating arm 42 to rotate in the opposite direction when receiving the steering signal.

[0093] In an embodiment of the present disclosure, a limit sensor 45 is arranged on the inner wall of the cavity 12 of the condenser, and is used to restrict the rotation range of the rotating arm 42. Since the second end of the rotating arm 42 reciprocates in a circular arc in the cavity 11 with the first end of the rotating arm 42 as the center, and the rotation arc is 360°, when the second end of the rotating arm 42 rotates to abut against the limit sensor, it rotates in the opposite direction, which can avoid entanglement of the water pipes in the water supply unit.

[0094] Reference Figures 1 to 8 In some embodiments, the transmission unit includes:

[0095] A motor 431, wherein the motor 431 is electrically connected to the control unit 3;

[0100] As an example, when the rotating arm 42 rotates in the counterclockwise direction and abuts against the limit sensor 45, the motor 431 stops and rotates in the clockwise direction until the rotating arm 42 contacts the limit sensor 45 again and then reverses direction, rotating alternately.

[0101] Reference Figures 6 to 12 In some embodiments, the water supply unit comprises:

In some embodiments, the adjustment angle range is ±30°.

[0107] Among them, the embodiment of the present disclosure does not impose any special restrictions on the connection method between the water pump 444 and the toggle rod 443, which can be a detachable connection method such as a plug-in type. At the same time, the embodiment of the present disclosure does not impose any special restrictions on the number of water pumps 444, and the number can be increased or decreased according to actual needs to achieve the required flushing density and water outlet swing effect, and avoid the occurrence of cleaning blind spots. The installation and replacement method of the water pump 444 is simple, which greatly reduces the consumables cost and assembly difficulty during the use of the condenser cleaning system. In some embodiments, the flushing speed and flushing intensity of the water pump 444 can be set by the Internet of Things control center 7, and the Internet of Things control center 7 can also set the number of water pumps 444 to be turned on.

[0108] In some embodiments, the water pump 444 is a micro water pump, and the number of water pumps 444 is 8.

The water inlet end of the water distributor 445 is connected to the water supply pipe 5, and the water outlet end is connected to the water inlet end of each water pump 444. Water enters the water distributor 445 from the water inlet end through the water supply pipe 5, and then flows to each water pump 444 respectively.

[0127] Reference Figures 13 to 19 , the main control module controls the voltage and conversion module, the water pump interface module, the water pump driver module, the motor driver module, the reciprocating motor driver module and the sensor module according to the instructions of the IoT control center 7. The voltage and conversion module converts the electric energy provided by the power supply device 6 into the working voltage of the controller; the main control module obtains the temperature data according to the sensor module, and generates a control instruction when the temperature is greater than the preset temperature threshold. Under the control of the main control module, the motor driver module and the reciprocating motor driver module drive the second end of the rotating arm 42 to reciprocate in an arc shape with the first end of the rotating arm 42 as the center. At the same time, the water pump driver module drives the water pump 444 in the water supply unit to discharge water according to the configured water pressure through the water pump interface module.

[0128] In order to enable those skilled in the art to more clearly understand the technical solution provided by the embodiments of the present disclosure, the working principle of the cleaning system for the condenser provided by the present disclosure is described below through specific embodiments:

[0129] Reference Figures 1 to 12The cleaning system of the condenser includes an automatic mode and a manual mode, wherein the automatic mode means that the cleaning system operates according to the working parameters pre-configured by the IoT control center 7. As an example, the cleaning system of the condenser includes: a temperature sensor 2, a control unit 3, a cleaning device, and an electric energy device 6, wherein the electric energy device 6 supplies power to the cleaning system of the condenser, and uses a solar panel 61 to charge a battery pack 62. The output voltage of the battery pack 62 is 6V, and it is composed of 6 2V batteries in a three-series and two-parallel manner, while doubling the capacity. The electric energy stored in the battery pack 62 can meet the needs of the cleaning system of the condenser to be in an uninterrupted working state for a long time. The solar panel 61 effectively utilizes clean natural resources and saves the cost of system operation.

[0130] The temperature sensor 2 detects the temperature of the heat sink fins 11 of the condenser in real time, and feeds back the detected temperature data to the control unit 3. Each control unit 3 has a unique identification ID, and the control unit 3 has a topic corresponding to the IoT control center 7. The control unit 3 can interact with the IoT control center 7 through the MQTT protocol to obtain the working parameters configured by the IoT control center 7; the IoT control center 7 is used to manage at least one control unit 3. The IoT control center 7 can set working parameters such as temperature threshold, flushing intensity, flushing speed, flushing interval, flushing frequency, mode switching type, etc. for the control unit 3, and can also create, subscribe and publish topics for each control unit 3, wherein the subscribed topic is used to instruct the control unit 3 to receive the temperature data of the temperature sensor 2, and the published topic is used to instruct the control unit 3 to send a control instruction to the cleaning device. The control unit 3 reads the temperature data of the temperature sensor 2 set on the heat sink fin 11 every 10 seconds. When the temperature corresponding to the temperature data is higher than the preset temperature threshold, the cleaning device is started to flush the heat sink fin 11.

[0131] The cleaning device receives the control command of the control unit 3 and starts the motor 431. The motor 431 drives the second synchronous wheel 433 located at the center of the supporting beam 41 to rotate through the transmission belt 434. The second synchronous wheel 433 is fixedly connected to the rotating arm 42. The rotation of the second synchronous wheel 433 further increases the torque, driving the rotating arm 42 to reciprocate in a circular arc in the cavity 12. The limit sensor 45 is installed on the inner wall of the cavity 12. When the rotating arm 42 rotates counterclockwise and contacts the limit sensor 45, the motor 431 stops rotating and turns to rotate clockwise until the rotating arm 42 contacts the limit sensor 45 again and then reverses direction, and repeats this alternation. The rotating arm 42 is fixedly connected to the water supply unit, and the water supply unit includes 8 water pumps 444. The water pumps 444 are miniature water pumps. The water inlet end of the water pump 444 is connected to the water outlet end of the water distributor 445. The driver in the control unit 3 controls the water supply pipe 5 to pump water, which is input into the water pump 444 through the diversion of the water distributor 445. The water outlet end of the water pump 444 generates a large water pressure, and the water output from the water pump 444 quickly flushes the heat sink fins 11, which has the effect of cleaning and cooling it.

[0132] A reciprocating motor 441 and a reciprocating connecting rod 442 are installed on the rotating arm 45. The reciprocating motor 441 drives the reciprocating connecting rod 442 to reciprocate in a circular arc shape by rotating the eccentric wheel. The reciprocating connecting rod 442 is fixedly connected to a toggle rod 443, and the toggle rod 443 is detachably connected to the water pump 444. The toggle rod 443 corresponds to the grooves of the mounting seat of the water pump 444, respectively, driving the water outlet end of the water pump 444 to swing at ±30° in the vertical direction with the surface of the heat dissipation fins 11, thereby solving the problem of flushing blind spots caused by the large distance between the water outlet ends of the water pump 444.

[0133] When the temperature data of the temperature sensor 2 read by the control unit 3 for three consecutive times within 30 seconds is lower than the preset temperature threshold, the water pump 444 stops working.

[0134] Manual mode means that the cleaning system operates according to the real-time instructions of the operator. As an example, the operator switches the mode switching type to manual mode in the IoT control center 7, customizes or adjusts the cleaning position, cleaning angle, cleaning time and cleaning intensity, etc., and sends a control instruction to the control unit 3 to start. During the cleaning process of the cleaning device, the rotating arm 45 first rotates counterclockwise, and when it touches the limit sensor 45, it stops rotating and adjusts the rotation direction to the reverse direction (i.e., clockwise). At this point, a flushing and cooling process is completed, and the cleaning is repeated until the operator controls the control unit 3 to send a control instruction to suspend the operation of the cleaning device.

[0135] The embodiment of the present disclosure detects the temperature of the cooling fins of the condenser through a temperature sensor, and uses a control unit to control the operation of the cleaning device in an intelligent and autonomous manner according to set working parameters based on the detected temperature, without the need for human control, thereby ensuring timely cleaning and rapid cooling and saving water resources to the greatest extent; the control unit can adjust the water outlet angle and position of the cleaning device, thereby controlling the cleaning position and cleaning angle of the cooling fins and avoiding cleaning blind spots.
