Description

Technical Field

[0001] This invention relates to the field of heat pipe array heat dissipation devices, specifically a heat pipe array heat dissipation device for a compressed air energy storage motor. Background Technology

[0002] Compressed air energy storage motors are used in compressed air energy storage systems and are devices that convert electrical energy into mechanical energy. During operation, they generate a large amount of heat. If not dissipated in time, this can lead to overheating, performance degradation, or even damage. Therefore, heat pipe array cooling devices are needed to dissipate heat. For example, Chinese patent application number 202410729629.3, filed on June 6, 2024, describes a high-efficiency heat pipe array radiator. During operation, it rapidly absorbs heat generated by components through a single heated base. The heat in the heated base is then dissipated by heat pipes and cooling... The heat pipe absorbs heat from the working fluid simultaneously, and the heat in the heat pipe is quickly dissipated through the air cooling system formed by the fins. At the same time, the heat is transferred to the cooling working fluid and dissipated by the air cooling system formed by the fins and the fan. Thus, it combines the rapid cooling of air cooling with the large heat capacity of water cooling. There is also a Chinese patent application with application number 202122523067.1 and application date of 2021-10-20, which describes a micro heat pipe array inverter heat sink. During use, it adopts a dual heat dissipation structure of heat dissipation fins and micro heat pipe array, which can quickly dissipate heat from the inverter, avoid damage to electronic components caused by excessive temperature inside the inverter, extend the service life of the inverter, and improve the stability of the product.

[0003] During prolonged use, dust will accumulate on the heat sink fins. The heat sink device mentioned in the above application does not have the function of assisting in dust removal during operation, which will affect the subsequent operation of the fins and the heat dissipation effect of the heat sink device. Summary of the Invention

[0004] The purpose of this invention is to provide a heat pipe array heat dissipation device for a compressed air energy storage motor, in order to solve the problem mentioned in the background art that the device does not have an auxiliary dust cleaning function during operation, which will affect the operation of the subsequent fins and the heat dissipation effect of the heat dissipation device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat pipe array heat dissipation device for a compressed air energy storage motor, comprising a body, a cover on the upper surface of the body, a hot air pipe bolted to the left side surface of the body, and a cold air pipe bolted to the right side surface of the body; a partition fixedly connected to the inner wall of the body, a thermoelectric generator mounted on the outer wall of the partition, a fan mounted on the rear side of the body, and a stator mounted inside the body; a heat pipe slidably disposed inside the partition, with the end of the heat pipe located outside the partition; a movable frame connected to the rear side of the body via a lifting mechanism; a heat-conducting plate connected to the lower surface of the movable frame via a reciprocating mechanism, and a heat dissipation plate fixedly connected to the outer wall of the heat-conducting plate; The surface of the heat-conducting plate is connected to a force-bearing plate via a movable mechanism, and a brush plate is fixedly connected to the lower surface of the force-bearing plate.

[0006] Preferably, the inner side of the body and the partition is a sealed cavity, and the sealed cavity is filled with refrigerant. The body has a porous structure inside, which enhances the phase change of the refrigerant. The thermoelectric generator is electrically connected to the fan. The heat pipes are arranged in an array on the partition, and the ends of the heat pipes are fixedly connected to a memory metal spring. The other side of the memory metal spring is fixedly connected to the inner front wall of the body, and the memory metal spring contracts when the temperature is high.

[0007] Preferably, heat-conducting rods are provided at equal intervals on the rear side of the machine body, and the ends of the heat-conducting rods are located inside the heat-conducting plate. A motor is bolted to the rear side of the machine body, and a guide rod is fixedly connected to the rear surface of the machine body.

[0008] Preferably, the lifting mechanism includes a connecting rod fixedly connected to the output end of the motor, and a fixing block is fixedly connected to the surface of the connecting rod. An inner shaft is fixedly connected to the upper surface of the movable frame, and long rods are sleeved and connected to both the surface of the inner shaft and the surface of the fixing block. The guide rod passes through the interior of the movable frame, and the left side of the guide rod is inverted "U" shape.

[0009] Preferably, an upper connecting block is fixedly connected to the upper surface of the heat-conducting plate, and a limiting rod is fixedly connected to the inner wall of the movable frame, with the limiting rod penetrating the interior of the upper connecting block.

[0010] Preferably, the reciprocating mechanism includes a guide rod fixedly connected to the rear side of the machine body, a guide groove is provided on the surface of the heat-conducting plate, the end of the guide rod is located inside the guide groove, and the guide groove is inclined.

[0011] Preferably, the active mechanism includes a rack fixedly connected to the back of the body, a connecting shaft rotatably disposed inside the heat-conducting plate, and a gear meshing with the rack is fixedly connected to the surface of the connecting shaft.

[0012] Preferably, a cam is fixedly connected to the surface of the connecting shaft, an outer plate is fixedly connected to the outer wall of the heat-conducting plate, and the left side of the outer plate is inverted "U" shape, and the outer plate penetrates through the interior of the force-bearing plate.

[0013] Preferably, a reset spring that provides elastic reset is fixedly connected to the lower surface of the force-bearing plate, and the other side of the reset spring is fixedly connected to the inner wall of the outer plate, and a damping rod is fixedly connected to the inner wall of the outer plate.

[0014] Preferably, the movable end of the damping rod is fixedly connected to the lower surface of the force-bearing plate, the brush plate is made of copper, and the brush plates are evenly distributed on the lower surface of the force-bearing plate.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: It employs a novel structural design, utilizing a memory metal spring that allows for contraction at high temperatures, enabling the heat pipe to move up and down. The heat pipe moves downwards when the external motor's operating power is high and upwards when the power is low, reducing air resistance. Simultaneously, a movable heat dissipation plate is included, increasing air convection and allowing the heat dissipation plate to come into contact with more air, thus accelerating heat dissipation and improving its effectiveness. Furthermore, a brush plate that reciprocates relative to the heat dissipation plate cleans dust from its surface, ensuring the heat dissipation plate's working efficiency. The specific details are as follows: The heat pipe array cooling device of this compressed air energy storage motor introduces hot air into the sealed cavity through a hot air pipe during use. At this time, the refrigerant absorbs heat, and then the hot air cools down, becoming cold air. It is then discharged through a cold air pipe and directed at the heat-generating area to cool it down. During this process, the brush plate is in a reciprocating motion, which can clean the heat sink plate and keep it in the best heat dissipation state, which facilitates the overall heat dissipation of the machine and improves work efficiency.

[0016] Furthermore, within the sealed cavity inside the machine body, a vacuum is drawn to lower the boiling point of the refrigerant. At the same time, the refrigerant inside is equipped with a porous structure. The porous structure enhances the phase change of the refrigerant, ensuring a low temperature on one side of the thermoelectric generator, thereby enabling the thermoelectric generator to generate electricity normally. The electricity generated by the thermoelectric generator powers the fan, which in turn optimizes the heat dissipation effect.

[0017] Furthermore, the heat pipe is encased in a wick structure, which has capillary properties, allowing the liquid working fluid to rise along the wick, thus optimizing the heat dissipation effect of the heat pipe.

[0018] The heat pipe array cooling device of this compressed air energy storage motor intermittently starts the motor when the machine is working. When the motor rotates, the movable frame moves vertically through the connecting rod, guide rod, fixed block and inner shaft. At this time, the movable frame drives the heat conduction plate and heat dissipation plate to move synchronously. Thus, the heat dissipation plate is in a moving state and can come into contact with more air, which optimizes the air convection effect and improves the heat dissipation effect.

[0019] Furthermore, as the heat-conducting plate descends, the guide rod and guide groove cause the heat-conducting plate to move. At this time, the upper connecting block slides on the surface of the limiting rod, thus widening the movement path of the heat-conducting plate and allowing it to come into contact with more air. This further enhances the air convection effect, improves the heat dissipation effect of the heat sink and the machine body, and increases work efficiency.

[0020] The heat pipe array cooling device of the compressed air energy storage motor has a heat pipe array. When the heat conduction plate moves in the horizontal direction, the connecting shaft rotates inside the heat conduction plate through gears and racks. When the connecting shaft rotates, it drives the cam to rotate synchronously. At this time, the force plate moves in a reciprocating linear motion in the vertical direction under the action of the cam thrust, the outer plate and the return spring. Then the force plate cleans the heat dissipation plate through the brush plate, ensuring the cleanliness of the heat dissipation plate surface.

[0021] Furthermore, the brush plate is made of copper, and the gap between the brush plate and the heat sink is relatively large. The brush plate can guide airflow through the heat sink, while the metal brush bristles assist in heat conduction, which may slightly improve heat dissipation. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] The present invention provides the following technical solution: a heat pipe array heat dissipation device for a compressed air energy storage motor.

[0026] Example 1: By using the hot air duct 3 and cold air duct 4, hot air can be cooled down to become cold air, which can then be used to cool other objects, such as... Figures 1-2 As shown, the device includes a body 1, with a cover 2 on its upper surface. A hot air duct 3 is bolted to the left side of the body 1, and a cold air duct 4 is bolted to the right side of the body 1. A partition 5 is fixedly connected to the inner wall of the body 1, and a thermoelectric generator 8 is installed on the outer wall of the partition 5. A fan 9 is installed on the rear side of the body 1, and a stator is installed inside the body 1. A heat pipe 6 is slidably installed inside the partition 5, with the end of the heat pipe 6 located on the outer side of the partition 5. The inner side of the body 1 and the partition 5 forms a sealed cavity, which is filled with refrigerant. The interior of the body 1 has a porous structure to enhance the phase change of the refrigerant. The thermoelectric generator 8 and the fan 9 are electrically connected. The heat pipes 6 are arranged in an array on the partition 5, and a memory metal spring 7 is fixedly connected to the end of the heat pipe 6. The other side of the memory metal spring 7 is fixedly connected to the front inner wall of the body 1, and the memory metal spring 7 contracts when it reaches a high temperature.

[0027] During use, hot air is introduced into the sealed cavity inside the unit 1 through the hot air duct 3. At this time, the refrigerant absorbs heat, and then the hot air cools down, becoming cold air, which is then discharged through the cold air duct 4. The cold air is then directed at the heat-generating location to cool it down. Inside the sealed cavity inside the unit 1, a vacuum is drawn to lower the boiling point of the refrigerant. At the same time, the refrigerant is filled inside and a porous structure is set. The porous structure enhances the phase change of the refrigerant and ensures that the temperature on one side of the thermoelectric generator 8 is low, thus enabling the thermoelectric generator 8 to generate electricity normally. The electricity generated by the thermoelectric generator 8 powers the fan 9, which optimizes the heat dissipation effect. Meanwhile, the heat pipe 6 is covered with a liquid wick structure, which has capillary properties. Liquid working fluid can climb along the liquid wick, optimizing the heat dissipation effect of the heat pipe 6.

[0028] Example 2: Unlike Example 1, the movable frame 14 allows the heat-conducting plate 20 and the heat dissipation plate 21 to move vertically, such as... Figures 2-6 As shown, a movable frame 14 is connected to the rear side of the machine body 1 via a lifting mechanism; a force plate 27 is connected to the surface of the heat-conducting plate 20 via a movable mechanism, and a brush plate 32 is fixedly connected to the lower surface of the force plate 27; heat-conducting rods 19 are provided at equal intervals on the rear side of the machine body 1, and the ends of the heat-conducting rods 19 are located inside the heat-conducting plate 20; a motor 10 is bolted to the rear side of the machine body 1, and a guide rod 13 is fixedly connected to the rear surface of the machine body 1.

[0029] The lifting mechanism includes a connecting rod 11 fixedly connected to the output end of the motor 10, and a fixing block 12 fixedly connected to the surface of the connecting rod 11. An inner shaft 15 is fixedly connected to the upper surface of the movable frame 14, and a long rod 16 is sleeved and connected to both the surface of the inner shaft 15 and the surface of the fixing block 12. A guide rod 13 passes through the interior of the movable frame 14, and the left side of the guide rod 13 is inverted "U" shape. An upper connecting block 26 is fixedly connected to the upper surface of the heat conduction plate 20. A limit rod 25 is fixedly connected to the inner wall of the movable frame 14, and the limit rod 25 passes through the interior of the upper connecting block 26.

[0030] When the machine body 1 is working, the motor 10 is started intermittently. When the motor 10 rotates, the movable frame 14 moves in the vertical direction through the connecting rod 11, the guide rod 13, the fixed block 12, and the inner shaft 15. At this time, the movable frame 14 drives the heat conduction plate 20 and the heat dissipation plate 21 to move synchronously. As a result, the heat dissipation plate 21 is in a state of moving in the vertical direction, which can come into contact with more air, optimize the air convection effect, and improve the heat dissipation effect.

[0031] Example 3: Unlike Example 2, the reciprocating mechanism allows the heat sink 21 and heat conduction plate 20 to move horizontally, further optimizing the heat dissipation effect. Figure 3 and Figure 4 as well as Figure 6As shown, the lower surface of the movable frame 14 is connected to a heat-conducting plate 20 via a reciprocating mechanism, and a heat dissipation plate 21 is fixedly connected to the outer wall of the heat-conducting plate 20; the reciprocating mechanism includes a guide rod 17 fixedly connected to the rear side of the body 1, a guide groove 18 is provided on the surface of the heat-conducting plate 20, the end of the guide rod 17 is located inside the guide groove 18, and the guide groove 18 is inclined.

[0032] As the heat-conducting plate 20 descends, the guide rod 17 and guide groove 18 cause the heat-conducting plate 20 to move. At this time, the upper connecting block 26 slides on the surface of the limiting rod 25, and the heat-conducting plate 20 also moves in the horizontal direction. The movement path of the heat-conducting plate 20 is wider, allowing the heat-conducting plate 20 to come into contact with more air, further enhancing the effect of air convection, improving the heat dissipation effect of the heat sink 21 and the body 1, and improving work efficiency.

[0033] Example 4: Unlike Example 3, the heat sink 21 can be cleaned using the force-bearing plate 27 and the brush plate 32. Figures 8-10 As shown, the active mechanism includes a rack 23 fixedly connected to the back of the body 1, a connecting shaft 22 rotatably arranged inside the heat conduction plate 20, and a gear 24 meshing with the rack 23 is fixedly connected to the surface of the connecting shaft 22, a cam 29 is fixedly connected to the surface of the connecting shaft 22, and an outer plate 28 is fixedly connected to the outer wall of the heat conduction plate 20. The left side of the outer plate 28 is inverted "U" shape, and the outer plate 28 passes through the interior of the force plate 27.

[0034] A reset spring 30, which plays an elastic reset role, is fixedly connected to the lower surface of the force plate 27, and the other side of the reset spring 30 is fixedly connected to the inner wall of the outer plate 28. A damping rod 31 is fixedly connected to the inner wall of the outer plate 28, and the movable end of the damping rod 31 is fixedly connected to the lower surface of the force plate 27. The brush plate 32 is made of copper and is evenly distributed on the lower surface of the force plate 27.

[0035] When the heat-conducting plate 20 moves horizontally, the gear 24 is in a moving state relative to the rack 23. At this time, the connecting shaft 22 rotates inside the heat-conducting plate 20 through the gear 24 and the rack 23. When the connecting shaft 22 rotates, it drives the cam 29 to rotate synchronously. When the cam 29 rotates and pushes the force plate 27, the force plate 27 descends. At this time, the return spring 30 is squeezed. When the cam 29 continues to rotate until it no longer pushes the force plate 27, the return spring 30 pushes the force plate 27 upward (the damping rod 31 increases stability). Then, under the action of the cam 29 thrust, the external plate 28 and the return spring 30, the force plate 27 makes a reciprocating linear motion in the vertical direction. Then, the force plate 27 cleans the heat sink 21 through the brush plate 32, ensuring the cleanliness of the surface of the heat sink 21, and thus ensuring the heat dissipation effect of the heat sink 21.

[0036] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
