Description

Technical Field

[0001] The invention belongs to the technical field of air source heat pump heat dissipation, and in particular relates to an air source heat pump heat dissipation device for a low temperature environment. Background Art

[0002] As a device that can still achieve efficient operation under low temperature conditions, the low-temperature environment air source heat pump plays a vital role in cold areas. It mainly uses air thermal energy to provide heating and hot water services in cold areas, which greatly meets people's living needs in low temperature environments. In the actual operation of the air source heat pump, the core components such as the compressor inside the heat pump system will inevitably generate a certain amount of heat during continuous operation. If this heat cannot be dissipated in a timely and effective manner, it will have a serious negative impact on the stable operation and performance of the system. Therefore, appropriate methods must be adopted for heat dissipation to ensure that the system can always remain in good working condition.

[0003] At present, the more common heat dissipation method is to use a cooling fan to assist the air source heat pump to dissipate heat. For example, the existing public patent (application number is CN202110541589.6) shows a low-temperature environment air source heat pump heat dissipation device. However, this heat dissipation device actually assists the air source heat pump in dissipating heat. There are some prominent problems: On the one hand, the speed of the cooling fan cannot be automatically adjusted and controlled according to the specific operating temperature state of the air source heat pump. During the operation of the air source heat pump, its operating temperature will change with different usage scenarios and workloads. When the operating temperature of the air source heat pump is too high, it means that the system generates more heat. At this time, a higher heat dissipation efficiency is required to reduce the system temperature to ensure the normal operation and performance of the equipment. However, if the cooling fan still maintains the original speed, it will not be able to meet this high heat dissipation demand, thereby affecting the heat dissipation effect. This may cause the system temperature to continue to rise, which in turn affects the stability and reliability of the equipment, and may even cause equipment failure; On the other hand, when the operating temperature of the air source heat pump is low, the heat generated by the system is relatively small, and excessively high heat dissipation efficiency is not required at this time. If the cooling fan still maintains a high speed, it will cause unnecessary waste of electricity, which not only increases the operating cost, but also does not meet the requirements of energy conservation and environmental protection. In addition, when the heat dissipation device recycles the hot air discharged by the air source heat pump, it lacks an effective filtering mechanism for the recycled hot air. The hot air discharged by the air source heat pump during operation may carry various pollutants such as dust and impurities. If the hot air is not effectively filtered during the recycling process, these pollutants will easily enter the air source heat pump system, which will cause pollution to the air source heat pump and affect the performance and life of the equipment.

[0004] To this end, we propose a low-temperature environment air source heat pump cooling device to solve the above problems. Summary of the invention

The driving shaft is rotatably arranged in the heat dissipation box, and the driving shaft is connected to the transmission shaft of the corresponding heat dissipation suction fan through the bevel gear group. The upper end of the driving shaft is connected to the driving motor.

[0008] In the above-mentioned low-temperature environment air source heat pump cooling device, the power self-adjusting mechanism is composed of two thermistors, a control box, an electromagnetic block, a permanent magnet block and a sliding rheostat. The two thermistors are fixedly arranged in the heat dissipation box, the control box is fixedly arranged on the outer wall of the heat dissipation box, and the electromagnetic block and the sliding rheostat are fixedly arranged in the control box. The electromagnetic block is fixedly connected to the permanent magnet block through a reset spring, and the permanent magnet block is fixedly connected to the sliding end of the sliding rheostat. The permanent magnet block is slidably connected to the inner wall of the control box, the electromagnetic block is connected in series with the two thermistors, and the sliding rheostat is connected in series with the drive motor.

[0009] In the above-mentioned low-temperature environment air source heat pump cooling device, the telescopic vibration mechanism is composed of an electromagnetic rod and a plurality of permanent magnet plates. The electromagnetic rod is fixedly arranged in the filter box, and each of the permanent magnet plates is embedded in the upper end surface of the filter mesh plate, and each permanent magnet plate is arranged opposite to the electromagnetic rod.

[0010] In the above-mentioned low-temperature environment air source heat pump cooling device, the intermittent control mechanism is composed of a control box, two push-trigger switches and an arc-shaped trigger block. The control box is fixedly arranged on the inner bottom surface of the heat dissipation box, and the drive shaft passes through the control box. The two push-trigger switches are fixedly arranged in the control box, and the two push-trigger switches are arranged opposite to each other. The arc-shaped trigger block is fixedly connected to the drive shaft, and the arc-shaped trigger block can intermittently trigger the push-trigger switch by rotating with the drive shaft, and the push-trigger switch is electrically connected to the electromagnetic rod.

[0011] In the above-mentioned low-temperature environment air source heat pump heat dissipation device, the lower inner wall of the filter box is of conical design, and the lower side of the filter box is fixedly connected to a sewage pipe.

[0012] In the above-mentioned low-temperature environment air source heat pump cooling device, a plurality of spring shock absorbers are fixedly arranged on the lower side of the base, and one end of each spring shock absorber away from the base is commonly fixedly connected to a support base.

[0013] In the above-mentioned low-temperature environment air source heat pump cooling device, a lifting seat is arranged at the lower side of the support seat, a plurality of hydraulic cylinders are fixedly arranged on the lifting seat, and the output ends of the hydraulic cylinders are fixedly connected to the support seat.

[0014] Compared with the existing technology, the advantages of a low temperature environment air source heat pump heat dissipation device are: 1. Intelligent power regulation to ensure stable and efficient operation of the equipment: Efficient heat dissipation at high temperatures: When the operating temperature of the air source heat pump is high, the temperature of the hot air flow guided to the heat sink by the suction pipe increases accordingly, and the resistance of the thermistor in the power self-adjusting mechanism automatically decreases. Due to the decrease in resistance, the current intensity of the electromagnetic block increases, which in turn leads to the increase in the magnetism of the electromagnetic block. At this time, the electromagnetic block will produce a repulsive force on the permanent magnet block, causing the permanent magnet block to move a certain distance. The movement of the permanent magnet block drives the sliding end of the sliding rheostat to move, so that the resistance of the sliding rheostat connected to the drive motor circuit automatically decreases; After the resistance value is reduced, the power of the drive motor is automatically increased. With the transmission cooperation of each bevel gear set, the speed of multiple heat dissipation suction fans is increased, which can significantly enhance the heat dissipation effect, timely and effectively dissipate the large amount of heat generated by the air source heat pump, avoid continuous increase in system temperature, ensure stable operation of the equipment under high temperature state, and reduce the risk of equipment failure caused by excessive temperature.

[0015] Energy-saving operation at low temperatures: When the temperature of the hot air flow guided by the intake pipe to the heat sink is low, the resistance of each thermistor will increase. Similarly, under the precise control of the power self-adjusting mechanism, the output power of the drive motor will be reduced, so that the heat dissipation suction fan remains at a low speed. In this way, when the operating temperature of the air source heat pump is low and the heat generated is relatively small, there will be no unnecessary waste of electricity due to the high speed operation of the cooling fan, which reduces the operating cost and meets the requirements of energy saving and environmental protection.

[0016] 2. Effective filtration and self-cleaning to ensure equipment performance and life: 1. Prevent pollutants from entering: The filter screen in the filter box effectively filters the recovered hot air flow. The hot air discharged by the air source heat pump during operation may carry various pollutants such as dust and impurities. The filter screen can block these pollutants and ensure that the purified hot air flow after filtration is guided to the air intake of the air source heat pump through the return pipe, thereby preventing pollutants from entering the air source heat pump system, avoiding pollution to the air source heat pump and ensuring the performance and life of the equipment.

[0017] 2. Automatic cleaning to maintain filtering performance: The electromagnetic rod in the telescopic vibration mechanism uses the magnetic changes when the power is on and off to intermittently attract the permanent magnet embedded in the upper end surface of the filter plate. Under the action of the permanent magnet, the filter plate moves back and forth, and at the same time, the reciprocating energy release of the reset telescopic spring causes the filter plate to vibrate. This vibration force can effectively remove impurities adhered to the filter plate, maintain the good filtering performance of the filter plate, and eliminate the need for frequent manual cleaning of the filter plate, thereby reducing maintenance costs.

[0018] 3. Intermittent control and adaptive vibration frequency to improve operating efficiency: 1. Automatic intermittent control: The arc-shaped trigger block in the intermittent control mechanism is fixedly connected to the drive shaft. During the rotation of the drive shaft, the arc-shaped trigger block rotates together. The arc-shaped trigger block will intermittently trigger two push-trigger switches. When the push-trigger switch is triggered, the electromagnetic rod will be intermittently energized and generate a magnetic field. This intermittent control method realizes the automatic control of the vibration of the filter plate and improves the intelligence level of the device.

[0019] 2. Adaptive vibration frequency: When the speed of the cooling suction fan increases or decreases, the amount of air directed to the filter box will change. The change in the air intake will cause the trigger frequency of the press-trigger switch to change synchronously with the speed of the drive shaft. When the air intake is large, the filter plate will automatically increase the vibration frequency to ensure the impurity removal effect of the filter plate. When the air intake is small, the filter plate will automatically reduce the vibration frequency to reduce energy consumption. This adaptive vibration frequency design can be dynamically adjusted according to actual working conditions to achieve more efficient operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] One side of the heat sink 2 is fixedly connected with an air intake pipe 7, and the other side of the heat sink 2 is connected with the filter box 3 through an exhaust pipe 8. The heat sink 2 is provided with a power self-adjusting mechanism 9 that cooperates with the driving mechanism 6.

[0025] An intermittent control mechanism 13 that cooperates with the driving mechanism 6 is provided in the heat dissipation box 2, and the intermittent control mechanism 13 is electrically connected to the telescopic vibration mechanism 12. The intermittent control mechanism 13 consists of a control box 131, two push-trigger switches 132 and an arc-shaped trigger block 133. The control box 131 is fixedly arranged on the inner bottom surface of the heat dissipation box 2, and the driving shaft 62 runs through the control box 131. The two push-trigger switches 132 are both fixedly arranged in the control box 131, and the two push-trigger switches 132 are arranged opposite to each other. The arc-shaped trigger block 133 is fixedly connected to the driving shaft 62, and the arc-shaped trigger block 133 follows the rotation of the driving shaft 62 to intermittently trigger the push-trigger switch 132. The push-trigger switch 132 is electrically connected to the electromagnetic rod 121. Through the arc-shaped trigger block 133, the rotation of the driving shaft 62 can be coordinated to make the push-trigger switch 132 intermittently triggered, thereby automatically controlling the intermittent power on and off of the electromagnetic rod 121.

[0026] The upper side of the filter box 3 is fixedly connected to a return pipe 14, the lower inner wall of the filter box 3 is of conical design, and the lower side of the filter box 3 is fixedly connected to a sewage pipe 16. The structural design of the lower side of the filter box 3 can cooperate with the sewage pipe 16 to facilitate subsequent sewage discharge.

[0027] A plurality of spring shock absorbers 17 are fixedly arranged on the lower side of the base 1, and a support seat 18 is fixedly connected to one end of each spring shock absorber 17 away from the base 1. The setting of the spring shock absorber 17 can effectively buffer the vibration generated when the heat dissipation device is working, and ensure the stability of the operation of the heat dissipation device. A lifting seat 19 is arranged on the lower side of the support seat 18, and a plurality of hydraulic cylinders 20 are fixedly arranged on the lifting seat 19, and the output end of the hydraulic cylinder 20 is fixedly connected to the support seat 18. The setting of the hydraulic cylinder 20 can adjust the use height of the heat dissipation device as needed.

[0028] The operating principle of the present invention is now described as follows: When using the heat dissipation device, firstly, the use height of the device can be adjusted by using the hydraulic cylinder 20 according to actual needs, then the air intake end of the air intake pipe 7 is accurately connected to the heat dissipation port of the air source heat pump housing, and the output end of the return pipe 14 is properly connected to the air intake port of the air source heat pump; During the working process, the driving motor 61 plays a key role. It can control the driving shaft 62 to rotate. Under the precise transmission cooperation of each bevel gear set 63, multiple heat dissipation suction fans 5 can rotate synchronously. Through the action of the suction pipe 7, the hot air flow generated when the air source heat pump is working can be discharged at a faster speed, thereby realizing an efficient heat dissipation function. The hot air flow guided by the exhaust pipe 8 will smoothly enter the filter box 3. In the filter box 3, the filter screen plate 10 plays an important filtering role. The purified hot air flow after filtering will be guided to the air intake of the air source heat pump through the return pipe 14. In this way, the air source heat pump can effectively utilize the heat energy in the return hot air flow; When the temperature of the hot air flow guided to the heat sink 2 by the air intake pipe 7 is too high, it means that the working temperature of the air source heat pump is at a high level at this time. In this case, the resistance of the thermistor 91 will automatically decrease. Due to the decrease in resistance, the current intensity of the electromagnetic block 93 is increased, thereby increasing the magnetism of the electromagnetic block 93. At this time, the electromagnetic block 93 will produce a repulsive force on the permanent magnet block 94, causing the permanent magnet block 94 to move a certain distance, and the movement of the permanent magnet block 94 will drive the sliding end of the sliding rheostat 95 to move. In this way, the resistance of the sliding rheostat 95 connected to the circuit of the drive motor 61 will automatically decrease. After the resistance is reduced, the power of the drive motor 61 will automatically increase, thereby increasing the speed of each heat dissipation suction fan 5, thereby significantly enhancing the heat dissipation effect. Conversely, when the temperature of the hot air flow guided to the heat sink 2 is low, the resistance of each thermistor 91 will increase. Similarly, under the precise control of the power self-adjusting mechanism 9, the output power of the drive motor 61 will decrease, so that the heat dissipation suction fan 5 is maintained at a low speed, thereby reducing the heat dissipation energy consumption. During the rotation of the driving shaft 62, the arc-shaped trigger block 133 will be driven to rotate together, and the arc-shaped trigger block 133 will intermittently trigger the two push-trigger switches 132. When the push-trigger switches 132 are triggered, the electromagnetic rod 121 will be intermittently energized and generate a magnetic field. The electromagnetic rod 121 that generates the magnetic field will reciprocate to attract each permanent magnet sheet 122. Under the action of the permanent magnet sheet 122, the filter screen plate 10 can move back and forth. At the same time, with the reciprocating energy release effect of the reset telescopic spring 11, the filter screen plate 10 can vibrate, and this vibration force can effectively vibrate In addition, when the rotation speed of each heat dissipation suction fan 5 increases or decreases, the amount of air introduced into the filter box 3 will change, and the change in the amount of air intake will cause the trigger frequency of the press trigger switch 132 to change synchronously. When the air intake is large, the filter plate 10 will automatically increase the vibration frequency to ensure the impurity removal effect of the filter plate 10, and when the air intake is small, the filter plate 10 will automatically reduce the vibration frequency, thereby reducing energy consumption and achieving more efficient operation.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
