Description

Technical Field

[0001] The present invention relates to the technical field of air cooler equipment, and particularly relates to a hot fluorine defrosting device for an air cooler. Background Art

[0002] An air cooler is a device specifically used to provide cooling air, which is widely used in heating, ventilation, and air conditioning systems, refrigeration, and freezing facilities. It absorbs heat from the air by circulating refrigerant, thereby providing cool air for indoor or environmental use. The hot fluorine defrosting device determines the formation of frost by monitoring the temperature of the evaporator, and automatically changes the flow direction of the refrigerant when necessary, introducing the heat from the compressor to the evaporator to melt the frost, avoiding the influence of the frost layer on the heat exchange efficiency, and ensuring the efficient operation of the air cooler.

[0003] The existing hot fluorine defrosting device for an air cooler, as shown in a Chinese application with the application number: 202022974828.0, a hot fluorine defrosting device for an air cooler, includes a compressor, a fluorine storage tank, a delivery pipe, an output pipe, a three-way valve, a condenser, a pair of intake pipes, an evaporator, a cold row pipe, a pair of return pipes, and a refrigeration fan; the fluorine in the fluorine storage tank forms a high-temperature and high-pressure gas through the compressor, and flows through the condenser, the evaporator, and finally into the cold row pipe in sequence, increasing the temperature of the cold row pipe to achieve the purpose of hot fluorine defrosting.

[0004] In the above-mentioned defrosting device, during the refrigeration stage, the low temperature causes the cold row pipe to contract; during the defrosting stage, the high temperature causes the cold row pipe to expand. Frequent contraction and expansion will cause the pipeline material to be subjected to repeated mechanical stress, increasing the risk of aging and fatigue of the cold row pipe. At the same time, it may cause the pipeline to crack or break, increasing the risk of loosening, air leakage, or leakage at the joints. Therefore, in the prior art, a temperature sensor is usually installed on the cold row pipe to detect the real-time temperature of the cold row pipe, ensuring that the temperature on the cold row pipe is within a certain range, and avoiding the situation that the cold row pipe expands excessively due to too high temperature and contracts excessively due to too low temperature.

[0005] When detecting the temperature of the cold row pipe through the temperature sensor to keep the cold row pipe within a certain range, the highest temperature reached by the cold row pipe is limited within this range, which may not ensure the best defrosting effect of the cold row pipe. At the same time, the lowest temperature of the cold row pipe is limited, and the best refrigeration effect of the air cooler cannot be ensured. Therefore, there is room for improvement. Summary of the Invention

By continuously adjusting the temperature of the medium in the cold row pipe, the cold row pipe is in the optimal defrosting or refrigeration state. At the same time, the deformation amount of the cold row pipe is controlled, delaying the aging and damage process of the cold row pipe, reducing the maintenance cost of the cold row pipe, and reducing the repair frequency of the cold row pipe.

[0024] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0025] Figure 1 It is a schematic diagram of the overall structure of the hot fluorine defrosting device of the cold air blower provided by the embodiment of the present invention; Figure 2 It is a schematic diagram of the overall structure of the measurement component of the fluorine defrosting device provided by the embodiment of the present invention; Figure 3 For Figure 2 The enlarged view at A in Figure 4 It is a schematic diagram of the overall structure of the trigger component of the fluorine defrosting device provided by the embodiment of the present invention; Figure 5 It is a schematic diagram of the overall structure of the speed regulation component of the fluorine defrosting device provided by the embodiment of the present invention.

[0026] A hot fluorine defrosting device for a cooling fan provided in this embodiment is applied to the scenario of frost formation on the cooling row pipes of the cooling fan. In this embodiment, by improving the structure of the defrosting device, the defrosting device can adjust the flow rate of the medium in the cooling row pipes according to the deformation amplitude of the cooling row pipes. At the same time, the temperature of the cooling row pipes is regulated, improving the defrosting efficiency and delaying the aging and damage process of the cooling row pipes.

[0027] Please refer to Figures 1 - 5 , a hot fluorine defrosting device for a cooling fan provided in this embodiment includes a box body 10, a fluorine storage tank 20, a compressor 30, a cooling row pipe 40, a measurement component 50, a speed regulation component 60, and a temperature control component. The fluorine storage tank 20, the compressor 30, the cooling row pipe 40, the measurement component 50, the speed regulation component 60, and the temperature control component are all arranged in the box body 10; the compressor 30 is used to pump the fluorine in the fluorine storage tank 20 into the cooling row pipe 40. The measurement component 50 is arranged on the cooling row pipe 40 and is used to detect the deformation amplitude of the cooling row pipe 40. When the measurement component 50 detects that the cooling row pipe 40 is at the hot extreme deformation value, the temperature control component reduces the defrosting temperature of the cooling row pipe 40, and the speed regulation component 60 reduces the delivery speed of the fluorine; when the measurement component 50 detects that the cooling row pipe 40 is at the cold extreme deformation value, the temperature control component increases the refrigeration temperature of the cooling row pipe 40, and the speed regulation component 60 increases the delivery speed of the fluorine.

[0028] Specifically, the formation of the frost layer and the change in the temperature of the cooling row pipe 40 will cause the deformation of the cooling row pipe 40. The measurement component 50 detects the deformation amplitude of the cooling row pipe 40 in real time, reflects whether there is frost layer accumulation, and monitors the deformation amplitude of the cooling row pipe 40 at different temperatures. The control terminal 100 determines whether the preset frost layer or frosting degree threshold is reached according to the deformation change value, and decides whether to start the defrosting process; the compressor 30 pumps the fluorine in the fluorine storage tank 20 into the cooling row pipe 40. When the fluorine gas flows through the cooling row pipe 40, a large amount of heat energy is released to melt the frost layer attached to the pipe wall; the temperature control component adjusts the pressure value and temperature value in the compressor 30 to realize the adjustment of the output temperature of the fluorine, ensuring that the fluorine gas is in the best temperature state when flowing in the cooling row pipe 40, which can effectively melt the frost layer while avoiding excessive expansion of the cooling row pipe 40 due to too high temperature, and reducing the large deformation of the cooling row pipe 40 at lower or higher temperatures; the measurement component 50 continuously monitors the change value of the deformation amount of the cooling row pipe 40 to ensure that the frost layer is completely melted and avoid overheating. The control terminal 100 instructs the speed regulation component 60 to adjust the delivery flow rate of the fluorine gas according to different deformation amounts of the cooling row pipe 40, so as to improve the defrosting efficiency; after the deformation amplitude returns to the normal range, the control terminal 100 instructs the speed regulation component 60 to adjust the delivery speed of the fluorine to return to the normal working state, and the system returns to the normal cooling mode. The measurement component 50 continuously monitors the state of the cooling row pipe 40 and prepares to detect the formation of the next frost layer.

[0029] The present invention monitors the deformation amplitude of the cold row pipe 40 through the measurement component 50, and adjusts the speed regulation component 60 and the temperature control component to perform corresponding operations. When the measurement component 50 detects that the cold row pipe 40 is at the thermal extreme deformation value, the temperature control component reduces the defrosting temperature of the cold row pipe 40, so that the expansion amplitude of the cold row pipe 40 decreases, avoiding large expansion deformation of the cold row pipe 40 during the defrosting process. At the same time, the speed regulation component 60 reduces the delivery speed of fluorine, enabling the medium 770 in the expanded cold row pipe 40 to fully exchange heat with the ice and frost, which is beneficial for rapidly cooling the cold row pipe 40; when the measurement component 50 detects that the cold row pipe 40 is at the cold extreme deformation value, the temperature control component increases the refrigeration temperature of the cold row pipe 40, so that the contraction amplitude of the cold row pipe 40 decreases, avoiding large contraction deformation of the cold row pipe 40 during the refrigeration process of the cold air conditioner. At the same time, the speed regulation component 60 increases the delivery speed of fluorine, enabling the medium 770 in the contracted cold row pipe 40 to fully exchange heat with the medium inside the pipe, which is beneficial for the cold row pipe 40 to rapidly return to temperature; by continuously adjusting the temperature of the medium 770 in the cold row pipe 40, the cold row pipe 40 is in the best defrosting or refrigeration state. At the same time, the deformation amount of the cold row pipe 40 is controlled, delaying the aging and damage process of the cold row pipe 40, reducing the maintenance cost of the cold row pipe 40, and reducing the repair frequency of the cold row pipe 40.

[0030] Exemplarily, since the expansion or contraction process of the cold row pipe 40 requires the pipe wall to reach a uniform temperature before overcoming the lattice resistance to generate deformation, the deformation of the cold row pipe 40 has a certain hysteresis relative to the temperature change of the pipe wall of the cold row pipe 40. Therefore, during the defrosting process, the temperature of the medium in the cold row pipe 40 is adjusted to make the cold row pipe 40 at the best defrosting temperature. Until the cold row pipe 40 reaches the thermal extreme deformation value, the temperature and flow rate of the medium in the cold row pipe 40 are reduced to lower its temperature, so as to avoid excessive expansion deformation, enabling the cold row pipe 40 to reach the longest best defrosting time, improving the defrosting effect of the cold row pipe 40 while avoiding excessive deformation of the cold row pipe 40; during the refrigeration process, the temperature of the medium in the cold row pipe 40 is adjusted to make the cold row pipe 40 at the best refrigeration temperature. Until the cold row pipe 40 reaches the cold extreme deformation value, the temperature and flow rate of the medium in the cold row pipe 40 are increased to raise its temperature, so as to avoid excessive contraction deformation, enabling the cold row pipe 40 to reach the longest refrigeration time, improving the refrigeration effect of the cold row pipe 40 while avoiding excessive deformation of the cold row pipe 40, and delaying the aging and damage process of the cold row pipe 40.

[0031] Please refer to Figure 2 and Figure 3, Further, the measurement component 50 includes an elastic layer 510, a cavity layer 520, and a rigid layer 530. The elastic layer 510 is coated on the cold row pipe 40, the rigid layer 530 is disposed outside the elastic layer 510, and the cavity layer 520 is disposed between the elastic layer 510 and the rigid layer 530. A plurality of deformation sacs 521 are equiangularly arranged in the cavity layer 520. Adjusting sacs 522 are arranged on both sides of the deformation sac 521. A medium 770 is filled in the deformation sac 521. A first channel 523 is arranged between the deformation sac 521 and the adjusting sac 522. Both the deformation sac 521 and the adjusting sac 522 are elastic structures. Specifically, when fluorine at a higher temperature is delivered to the cold row pipe 40, the cold row pipe 40 expands due to heat, causing the elastic layer 510 to be squeezed towards the direction close to the rigid layer 530. The cavity layer 520 is compressed, and the medium 770 filled in the deformation sac 521 is discharged into the adjusting sac 522 through the first channel 523 after the deformation sac 521 is squeezed by the elastic layer 510; when the cavity layer 520 is squeezed to the minimum compression space, the medium 770 in the adjusting sac 522 is discharged outwards; when the cold row pipe 40 is frosted, the temperature of the cold row pipe 40 decreases, causing the pipe to contract, causing the elastic layer 510 to contract away from the rigid layer 530, the cavity layer 520 expands, the deformation sac 521 expands, and the medium 770 filled in the adjusting sac 522 flows into the deformation sac 521 through the first channel 523; when the cavity layer 520 expands to the maximum expansion space, the external medium 770 flows into the adjusting sac 522. Among them, the minimum compression space and the maximum expansion space are preset values. Through the action of the deformation sac 521 and the medium 770, the deformation amplitude of the cold row pipe 40 is quantified. By feeding back the deformation degree of the cold row pipe 40, the temperature change and frosting condition of the cold row pipe 40 are directly reflected, enabling the control terminal 100 to more accurately monitor the frosting degree of the cold row pipe 40 and avoid blind or excessive operations; more refined defrosting control is achieved, such as adjusting the defrosting temperature and time according to different frosting degrees, ensuring that the frost layer is completely melted without residue, improving the refrigeration efficiency, and at the same time, avoiding the aging caused by excessive deformation of the cold row pipe 40.

[0032] Please refer to Figure 4, Further, the hot fluorine defrosting device further includes a trigger assembly 70. The trigger assembly 70 includes a liquid storage tank 710, a spring 720, a locking seat 730, a guide rod 740, and a trigger rod 750. The locking seat 730 is connected to the inner bottom surface of the liquid storage tank 710 through the spring 720 and slides along the liquid storage tank 710. A liquid storage chamber 760 is provided between the bottom of the locking seat 730 and the liquid storage tank 710. The liquid storage chamber 760 is filled with a medium 770, and the liquid storage chamber 760 is connected to the adjusting bladder 522. A guide rail 780 is provided on the locking seat 730. One end of the guide rod 740 is hinged to the liquid storage tank 710, and the other end rotates clockwise or counterclockwise along the guide rail 780. A through hole 790 is provided at the top of the liquid storage tank 710. One end of the trigger rod 750 is fixed to the locking seat 730, and the other end slides in the through hole 790. The trigger rod 750 is electrically connected to the control terminal 100 and is used to trigger different operating states of the speed regulating assembly 60 and the temperature control assembly. Specifically, the medium 770 in the liquid storage chamber 760 and the adjusting bladder 522 flows freely. When the adjusting bladder 522 is squeezed, the medium 770 in the adjusting bladder 522 is discharged into the liquid storage chamber 760, and the medium 770 in the liquid storage chamber 760 increases. When the adjusting bladder 522 expands, the medium 770 in the liquid storage chamber 760 flows into the adjusting bladder 522, and the medium 770 in the liquid storage chamber 760 decreases. When the medium 770 in the liquid storage chamber 760 increases or decreases, the locking seat 730 slides along the liquid storage tank 710. During the sliding process of the locking seat 730, one end of the guide rod 740 is hinged to the liquid storage tank 710, and the other end slides in the guide rail 780. The trigger rod 750 is electrically connected to the control terminal 100. When the guide rod 740 slides to different positions, different defrosting states are triggered, so that the control terminal 100 can regulate the temperature and rate of defrosting according to the real-time state of the cold row pipe 40, and realize the precise control of the defrosting process.

[0033] Please refer to Figure 4, Further, the guide rail 780 is a closed structure connected end to end. A first limit point 781 is provided at the bottom of the guide rail 780, and a second limit point 782 is provided at the top of the guide rail 780. The end of the guide rod 740 is located at the first limit point 781, and the trigger rod 750 triggers the first state; the end of the guide rod 740 slides from the first limit point 781 to the second limit point 782, and the trigger rod 750 slides in the first direction and triggers the second state; the end of the guide rod 740 is located at the second limit point 782, and the trigger rod 750 triggers the third state; the end of the guide rod 740 slides from the second limit point 782 to the first limit point 781, and the trigger rod 750 slides in the second direction and triggers the fourth state. Specifically, when the cavity layer 520 enters the compression state from the initial state, the end of the guide rod 740 is located at the second limit point 782, and the trigger rod 750 triggers the third state; when the cavity layer 520 is compressed to the minimum compression space, the end of the guide rod 740 slides from the second limit point 782 to the first limit point 781, and the trigger rod 750 slides in the second direction and triggers the fourth state; when the cavity layer 520 enters the diastolic state from the initial state, the end of the guide rod 740 is located at the first limit point 781, and the trigger rod 750 triggers the first state; when the cavity layer 520 expands to the maximum diastolic space, the end of the guide rod 740 slides from the first limit point 781 to the second limit point 782, and the trigger rod 750 slides in the first direction and triggers the second state. According to the deformation amount of the cold row tube 40, different defrosting states are triggered to realize the classification of defrosting intensity levels, and the most suitable defrosting strategy is automatically selected for different frosting environments to ensure the continuous and stable operation of the equipment; at the same time, the mechanical structure is used to limit the state switching, effectively avoiding the influence brought by electronic failures and improving the reliability of the system.

[0034] Please refer to Figure 5 , Further, a delivery pipe 80 is provided between the cold row tube 40 and the compressor 30. The speed regulation assembly 60 is arranged in the delivery pipe 80. The speed regulation assembly 60 includes a fixed block 610, a sliding block 620 and a driving assembly 630. The fixed block 610 is fixed in the delivery pipe 80. The end faces of the fixed block 610 and the sliding block 620 that are close to each other are inclined and parallel. The driving assembly 630 is used to drive the sliding block 620 to move in a direction close to or away from the fixed block 610. Specifically, both the fixed block 610 and the sliding block 620 are arranged in the delivery pipe 80 along the axial direction of the delivery pipe 80. Since the end faces of the sliding block 620 and the fixed block 610 that are close to each other are parallel, when the sliding block 620 moves in a direction close to the fixed block 610, the channel between the two becomes narrower, and thus the fluorine delivery channel becomes narrower, and the fluorine delivery rate decreases; when the sliding block 620 moves in a direction away from the fixed block 610, the channel between the two becomes larger, and the fluorine delivery rate increases, realizing the adjustment of the fluorine delivery rate; by dynamically adjusting the fluorine delivery rate, it is ensured that rapid defrosting is achieved under different frosting conditions, while avoiding overheating or energy waste.

[0035] Further, when in the first state, the speed control assembly 60 is commanded to perform a deceleration operation, and the temperature control assembly is commanded to perform a temperature reduction operation; when in the second state, the speed control assembly 60 is commanded to perform a deceleration operation, and the temperature control assembly is not triggered; when in the third state, the speed control assembly 60 is commanded to perform an acceleration operation, and the temperature control assembly is commanded to perform a temperature increase operation; when in the fourth state, the speed control assembly 60 is commanded to perform an acceleration operation, and the temperature control assembly is not triggered.

[0036] When the trigger rod 750 slides in the first direction, the sliding block 620 is driven to slide towards the fixed block 610; when the trigger rod 750 slides in the second direction, the sliding block 620 is driven to slide away from the fixed block 610. Specifically, when the trigger rod 750 slides in the first direction, the defrosting device is in the second state, and the speed control assembly 60 is commanded to perform a deceleration operation. At this time, the sliding block 620 moves towards the fixed block 610; when the trigger rod 750 slides in the second direction, the defrosting device is in the fourth state. At this time, the sliding block 620 moves away from the fixed block 610. The trigger rod 750 slides in two directions, driving the sliding block 620 to move axially, corresponding to different defrosting states respectively. The defrosting force is dynamically adjusted according to the actual state of the pipeline, avoiding excessive or insufficient defrosting force. Through the synchronous movement of the trigger rod 750 and the sliding block 620, the input flow rate of fluorine is adaptively adjusted according to the deformation amplitude of the cold row pipe 40, achieving fine control of the flow rate, achieving fast and stable response of the speed control assembly 60, thereby improving the operation efficiency of the equipment; the two-way sliding of the trigger rod 750 compactly and reliably realizes multi-stage state switching.

[0037] Please refer to Figure 2 and Figure 3 Furthermore, a boosting balloon 511 is arranged on the elastic layer 510, and the boosting balloon 511 is arranged opposite to the deformation balloon 521. Specifically, the boosting balloon 511 is made of a silicone rubber balloon. Silicone rubber has a certain linear thermal expansion coefficient. When the cold row pipe 40 expands due to heat, the boosting balloon 511 expands accordingly. When the cold row pipe 40 contracts due to cooling, the boosting balloon 511 contracts accordingly; when the cold row pipe 40 expands due to heat and causes the elastic layer 510 to deform, the boosting balloon 511 expands and applies a concentrated force on the deformation balloon 521, enabling the deformation balloon 521 to generate a relatively obvious compressive deformation amount; when the cold row pipe 40 contracts due to cold and causes the elastic layer 510 to deform, the boosting balloon 511 contracts, reducing the acting force on the deformation balloon 521, enabling the deformation balloon 521 to generate a relatively obvious expansion deformation amount. The deformation balloon 521 can more sensitively reflect the deformation change of the elastic layer 510, thereby improving the accuracy of deformation measurement; at the same time, the boosting balloon 511 improves the response sensitivity and accuracy of the deformation balloon 521 through concentrated application of force.

[0038] Please refer to Figure 2 and Figure 3 。Furthermore, the deformation bladder 521 is ellipsoidal, and both ends of the deformation bladder 521 along the long axis direction are respectively in contact with the top surface and the bottom surface of the cavity layer 520. Specifically, the ellipsoidal structure has a large elastic deformation space, especially in the long axis direction, and can adapt to a large deformation amplitude. Compared with a spherical shape, the ellipsoidal shape has a greater stretching ability in the long axis direction, which helps to capture the small or severe deformation of the cold row pipe 40; at the same time, the ellipsoidal design can balance the stress concentration points, reduce local stress concentration, and avoid material fatigue or damage caused by stress concentration; both ends are in contact with the top surface and the bottom surface of the cavity layer 520, ensuring that when the deformation bladder 521 deforms, its deformation state can be accurately transmitted to the cavity layer 520, which helps to obtain the most real deformation information of the cavity layer 520.

[0039] Please refer to Figure 1 。Furthermore, one end of the cold row pipe 40 far from the delivery pipe 80 is connected to the evaporator 90. Specifically, the recovered thermal energy can be used to heat or preheat the evaporator 90, thereby reducing the dependence on the compressor 30 and other energy sources inside the refrigerant heat pump system and reducing energy consumption. In the cold air blower system, the main function of the cold row pipe 40 is to absorb or release heat through the gas flowing through the pipe to adjust the temperature. In some working conditions, the pipe will absorb excess thermal energy. If this thermal energy can be effectively recovered, it can reduce the external energy input of the system and improve the overall energy efficiency. By connecting the distal end of the cold row pipe 40 to the evaporator 90, the system can transfer the waste heat to the evaporator 90 and utilize the refrigerant or auxiliary heating system in the evaporator 90 to recycle the thermal energy and avoid waste; recover the excess heat of the cold row pipe 40, and the excess heat is reused, such as used to preheat the air in the evaporator 90 in advance, heat the ventilation path or preheat the air, improving the energy utilization efficiency.

[0040] In summary, the hot fluorine defrosting device provided in this embodiment has the advantages of improving the control accuracy of the defrosting function and delaying the aging and damage process of the cold row pipe 40.
