Description

Technical Field

[0001] The invention relates to the technical field of blowers, in particular to a heat dissipation device of a blower. Background Art

[0002] A blower is a blade rotary gas compression machine. Gas is sucked into an air intake chamber and the impeller does work on the gas to increase the gas pressure, velocity and temperature. As a wind outlet device, the blower requires a motor as its indispensable driving device. In order to prevent the motor from overheating during operation, a heat dissipation mechanism is usually set on the blower to dissipate the heat of the motor.

[0003] After searching, the patent document with publication number CN115021492B provides a cooling structure for a closed blower motor, wherein, by installing an air supply pipe on the blower outlet pipe, a part of the wind originally flowing out of the outlet pipe is led into the blower motor, and the motor is cooled by air cooling. Although this method can cool the motor, it will inevitably cause the air volume at the blower outlet pipe to decrease, and the air volume does not meet the standard, affecting the use effect. At the same time, the cooling structure in the above device is connected to the blower as a whole. The cooling structure can only be applied to the current blower and is not convenient for disassembly and assembly. When the blower is replaced, it is necessary to re-manufacture cooling structures of different specifications, and the use cost is high.

The surface of the blower motor end is cooled by air cooling. The multiple heat dissipation units in the heat dissipation device are connected to the inside of the blower motor end through heat conduction rods, guiding the heat inside the motor end to the heat dissipation pipes of the heat dissipation units, and absorbing the heat inside the motor through the refrigerant in the pipes. The combination of liquid cooling and air cooling is used to cool the motor of the blower from both the inside and the outside at the same time, with a faster heat dissipation speed and better effect; In the present invention, the refrigerant circulates in the pipeline. The power source for the refrigerant to circulate is the heat energy inside the blower motor.

On the one hand, it drives the refrigerant to circulate, and on the other hand, it cools the inside of the motor through the circulating refrigerant. The product structure is more compact, resources are fully recycled and utilized, and it is more environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS

In the drawings or the description, similar or identical parts are denoted by the same reference numerals, and in actual applications, the shapes, thicknesses or heights of the various components can be enlarged or reduced. The various embodiments listed in the present invention are only used to illustrate the present invention and are not intended to limit the scope of the present invention. Any obvious modification or change made to the present invention does not depart from the spirit and scope of the present invention.

[0034] Please refer to Figures 1 - 3, in the embodiments of the present invention, a heat dissipation device for a blower includes a blower 1 and a heat dissipation device 2. The heat dissipation device 2 is installed on one side of the motor end of the blower 1. The heat dissipation device 2 dissipates heat from both the inside and outside of the motor end of the blower 1. A conduit 13 is connected between the heat dissipation device 2 and the air outlet pipe of the blower 1. The conduit 13 is used to divert the air blown out by the heat dissipation device 2 into the air outlet pipe of the blower 1, thereby increasing the air volume of the air outlet pipe of the blower 1 and fully recycling and utilizing electric power resources; The heat dissipation device 2 includes an end cover 3, a fan blade 4, a connecting cylinder 5, a heat dissipation mechanism 6, a connecting ring 7, a wind ring 8, a mounting plate 9 and a wind hood 10. The connecting cylinder 5 is a cylindrical structure with both ends penetrating. One end of it is fixedly connected to the end cover 3, and the other end is sleeved and fixed on the heat dissipation mechanism 6. A self-locking structure 51 is provided between the connecting cylinder 5 and the heat dissipation mechanism 6. The self-locking structure 51 is used to quickly disassemble and assemble the connecting cylinder 5 and the heat dissipation mechanism 6, facilitating the user to repair and maintain the heat dissipation mechanism 6; The fan blade 4 is rotatably connected to one side of the connecting cylinder 5 close to the end cover 3, and one end of the rotating shaft of the fan blade 4 is fixedly connected to one end of the motor shaft of the blower 1. The end cover 3, the fan blade 4 and the connecting cylinder 5 cooperate with each other to form a blowing mechanism for blowing air to the heat dissipation mechanism 6 and the motor end of the blower 1 at the same time for heat dissipation. The heat dissipation mechanism 6 is sleeved outside the motor housing of the blower 1, and a gap is reserved between the two for air flow; The connecting ring 7 is sleeved and fixed on the other end of the heat dissipation mechanism 6, and a wind ring 8 is fixed on one side of the connecting ring 7. A mounting plate 9 is fixed on one side of the wind ring 8. The heat dissipation device 2 is installed and fixed on one side of the motor end of the blower 1 through the mounting plate 9. After being fixed, the heat dissipation device 2 and the blower 1 form an integral body. The motor end of the blower 1 is located inside the heat dissipation device 2. A plurality of through air inlet holes 31 are evenly opened on the inner wall of one side of the end cover 3, and a plurality of through air outlet holes 81 are arranged at equal intervals around the inner wall of the wind ring 8; The wind hood 10 is sleeved outside the wind ring 8, and an annular groove is opened on the inner wall of the wind hood 10 corresponding to the wind ring 8. The air inside the wind ring 8 flows out from the air outlet holes 81 and flows into the groove on the inner wall of the wind hood 10. A semi-circular air guiding pipe 11 is fixed outside the wind hood 10. The shape of the air guiding pipe 11 is adapted to the wind hood 10. Both ends of the air guiding pipe 11 are inserted into the wind hood 10 and communicated with the inside of the wind hood 10. After the air guiding pipe 11 is communicated with the wind hood 10, the air flow in the wind hood 10 can be guided into the pipeline. A confluence pipe 12 is fixed at the bottom of the air guiding pipe 11, and the air guiding pipe 11 is internally communicated with the confluence pipe 12. The connecting ring 7, the wind ring 8, the mounting plate 9, the wind hood 10, the air guiding pipe 11 and the confluence pipe 12 cooperate with each other to form an air guiding mechanism for guiding and converging the air flow generated by the blowing mechanism; One end of the manifold 12 and one end of the air outlet pipe of the blower 1 are both fixed with quick connectors 14. The two ends of the conduit 13 are respectively connected and fixed to one end of the manifold 12 and one end of the air outlet pipe of the blower 1 through the corresponding quick connectors 14. The quick connectors 14 are used for quickly plugging and unplugging the conduit 13. The air flow introduced by the air guiding mechanism is sent into the air outlet pipe of the blower 1 through the conduit 13, so as to increase the air output of the blower 1. When the blower 1 operates, the fan blade 4 connected to its motor shaft rotates synchronously, sucking the external cold air into the interior of the heat dissipation device 2 from the air inlet hole 31. The cold air will flow in the gap between the heat dissipation mechanism 6 and the motor housing of the blower 1. During the flowing process, the heat on the heat dissipation mechanism 6 and the motor housing is taken away, and finally flows out from one side of the air outlet hole 81. The fan blade 4, the air inlet hole 31 and the air outlet hole 81 cooperate with each other to form an air circulation inside the heat dissipation device 2. The motor housing of the blower 1 is cooled by air through the flowing cold air. The external air flows out from the air outlet hole 81 and then enters the interior of the wind hood 10 and is led outwards through the air guiding pipe 11. After being led out, it is collected through the manifold 12. The manifold 12 is connected to the conduit 13, and the conduit 13 is connected to the air outlet pipe of the blower 1. Finally, the air flow generated by the rotation of the fan blade 4 will be transported to the air outlet pipe of the blower 1 to enhance the air output intensity and air output of the blower 1.

[0035] Please refer to Figure 4 As shown, the heat dissipation mechanism 6 includes an outer cylinder 61 and an inner cylinder 62. The outer cylinder 61 is nested outside the inner cylinder 62, and there is a cavity 63 reserved between the two. A plurality of heat dissipation units 64 are evenly arranged around the cavity 63. The plurality of heat dissipation units 64 cooperate with each other to form a complete heat dissipation module for simultaneously dissipating heat in multiple directions inside the motor end of the blower 1 to ensure uniform heat dissipation. The inner cylinder 62 is sleeved on the motor end of the blower 1, and there is a gap reserved between the two to allow air to flow through. A support ring 65 is arranged between the plurality of heat dissipation units 64. The support ring 65 is slidably sleeved on one end of the plurality of heat dissipation units 64. The plurality of heat dissipation units 64 are tightened and positioned through the support ring 65 to form an integral body. Both ends of the outer cylinder 61 are connected with sealing plates 66 through bolts. The two sealing plates 66 cooperate to package both ends of the cavity 63, making the cavity 63 airtight and the plurality of heat dissipation units 64 located in a sealed environment.

[0036] Please refer to Figure 5, the heat dissipation unit 64 includes a first heat dissipation pipe 641, a second heat dissipation pipe 642, an arc-shaped conduit 643, a heat exchange pipe 644, and a heat conducting rod 645. The interiors of the pipes of the first heat dissipation pipe 641 and the second heat dissipation pipe 642 are both filled with a refrigerant with high heat exchange efficiency (hereinafter referred to as refrigerant). One side of the bottoms of the first heat dissipation pipe 641 and the second heat dissipation pipe 642 is fixedly provided with a heat conducting rod 645. One ends of the two heat conducting rods 645 both pass through the inner wall of the inner cylinder 62, the inner wall of the motor housing of the blower 1, and extend into the interior of the motor end of the blower 1. The heat inside the motor of the blower 1 is conducted to the first heat dissipation pipe 641 and the second heat dissipation pipe 642 through the two heat conducting rods 645, and the interior of the blower motor is cooled by the two heat dissipation pipes; The arc-shaped conduit 643 and the heat exchange pipe 644 are arranged oppositely, and they are respectively located on both sides of the first heat dissipation pipe 641 and the second heat dissipation pipe 642. One ends of the adjacent sides of the first heat dissipation pipe 641 and the second heat dissipation pipe 642 are respectively fixed at both ends of the arc-shaped conduit 643, and the other ends of the adjacent sides of the first heat dissipation pipe 641 and the second heat dissipation pipe 642 are respectively fixed at both ends of the heat exchange pipe 644. The heat exchange pipe 644 is of a U-shaped rotary structure. The heat exchange pipe 644 is arranged outside the corresponding sealing plate 66, and the heat exchange pipe 644 is located in the cavity inside the connecting cylinder 5. Check valves are installed inside the pipes of the arc-shaped conduit 643 and the heat exchange pipe 644 to ensure the one-way flow of the refrigerant in the pipes. In this embodiment, the refrigerant flows from one side of the arc-shaped conduit 643 to one side of the heat exchange pipe 644. When the refrigerant enters the heat exchange pipe 644, the surface of the heat exchange pipe 644 is blown by the rotating fan blade 4, which can cool the refrigerant in the pipe, enabling the refrigerant to be reused.

[0037] Please refer to Figures 6 - 7 , heating tubes 646 are embedded and installed inside the first heat dissipation pipe 641 and the second heat dissipation pipe 642. One side inside each of the two heating tubes 646 is fixedly provided with a heat conducting block 647. The two heat conducting blocks 647 are respectively connected and fixed to one end of the corresponding heat conducting rod 645. On the other side inside each of the two heating tubes 646, a piston 648 is slidably connected. Hydraulic oil with high thermal expansion coefficient (hereinafter referred to as heat medium) is filled between the piston 648 and the heat conducting block 647 inside each of the two heating tubes 646. One side of each of the two pistons 648 is fixedly provided with a piston rod 649; One end of each of the two piston rods 649 slidably penetrates through the inner wall of one side of the corresponding heating tube 646 and extends into the corresponding heat dissipation tube. One end of each of the two piston rods 649 is fixed with a pressing disc 6411. The two pressing discs 6411 are respectively slidably connected in the corresponding first heat dissipation tube 641 and second heat dissipation tube 642. And sealing rings 6413 are sleeved and fixed on the outer circumferences of the two pressing discs 6411. When the pressing disc 6411 moves, it can push the refrigerant on one side of it forward. The moving direction of the pressing disc 6411 in the first heat dissipation tube 641 is opposite to the moving direction of the pressing disc 6411 in the second heat dissipation tube 642, which is used to guide and push the refrigerant in the pipeline, so that the refrigerant can circulate in the pipeline; Return springs 6410 are sleeved on the two piston rods 649. The two ends of the two return springs 6410 are respectively connected and fixed to the corresponding pressing disc 6411 on one side and the corresponding heating tube 646 on one side. Through holes 6412 that penetrate through both ends are formed on the disc surfaces of the two pressing discs 6411. The through holes 6412 are used for the flow of the refrigerant. Baffles 6414 are arranged on the sides of the two pressing discs 6411 away from the corresponding piston rods 649; Rotating shafts 6415 are arranged on the two baffles 6414. The two baffles 6414 are respectively rotatably connected to one side of the corresponding through hole 6412 through the corresponding rotating shafts 6415. And sealing gaskets are arranged on the side surfaces of the two baffles 6414 facing the through hole 6412. The baffle 6414 is used to block the through hole 6412. Return springs 6416 are sleeved on the two rotating shafts 6415. The two ends of the two return springs 6416 are respectively connected and fixed to the corresponding baffle 6414 and the corresponding pressing disc 6411. In the natural state, the baffle 6414 is tightly attached to one side of the through hole 6412 by the torsion force of the return spring 6416, preventing the refrigerant on one side of the pipeline from flowing to the other side through the through hole 6412 without being stressed; In this embodiment, the heat inside the motor end of the blower 1 is guided and transferred to the heat conducting block 647 through the heat conducting rod 645. The heat conducting block 647 generates heat inside the heating tube 646. The inside of the heating tube 646 is filled with a heat medium. When the temperature inside the pipeline rises, the heat medium expands due to heat, pushing the piston 648 to move inside the heating tube 646. The piston rod 649 on one side of the piston 648 moves synchronously, driving the pressing disc 6411 to move forward inside the heat dissipation tube, and pushing the refrigerant on one side of the pressing disc 6411 forward. Among them, the refrigerant in the first heat dissipation tube 641 is pushed forward and enters the heat exchange tube 644, and the refrigerant in the second heat dissipation tube 642 is pushed forward and enters the arc-shaped conduit 643. The refrigerant flows along the pipeline and circulates between the first heat dissipation tube 641 and the second heat dissipation tube 642. When the refrigerant enters the heat exchange tube 644, the rotating fan blade 4 blows air to cool it. When the refrigerant enters the heat dissipation tube, the refrigerant absorbs heat by contacting the inner wall of the heating tube 646; After the heat in the heating tube 646 is absorbed, the heat medium inside it cools down and contracts, and the heat medium no longer exerts pressure on the piston 648. The piston 648 and the piston rod 649 are reset backward under the action of the return spring 6410. At this time, the extrusion disc 6411 moves backward in the heat dissipation tube, and the refrigerant circulates into the side of the heat dissipation tube corresponding to the heating tube. As the extrusion disc 6411 continues to move, the refrigerant can no longer be compressed, and the refrigerant will resist and push the baffle 6414 to rotate upward, opening the through hole 6412. Then the refrigerant flows from the through hole 6412 to the other side inside the heat dissipation tube. As the heat dissipation continues, the piston 648 and the piston rod 649 continuously reciprocate back and forth inside the heat dissipation tube, driving the refrigerant to circulate in the pipeline, and cooling the inside of the motor end of the blower 1 through the circulating refrigerant.

[0038] Please refer to Figure 8 , there are two upper and lower arc-shaped protrusions 101 arranged in the groove on the inner wall of the wind hood 10, and the inside of the wind hood 10 is divided into two left and right air ducts 102 by the two arc-shaped protrusions 101. The heights of the two arc-shaped protrusions 101 both decrease from their middle positions to their two sides. Correspondingly, the widths of the two left and right air ducts 102 gradually increase from the top or bottom of the wind hood 10 to their two sides until reaching the maximum at the connection between the wind hood 10 and the air guide pipe 11. The purpose of doing this is to fully converge the air flow, make the air flow circularly, reduce the frictional resistance between the air flow and the inner wall of the wind hood 10, reduce the loss of air flow kinetic energy, and ensure that when the air flow reaches the connection between the left and right ends of the wind hood 10 and the air guide pipe 11, it can flow out smoothly.

[0039] Please refer to Figure 2 , Figure 3 , Figure 9 , Figure 10 , Figure 11 and Figure 12 , quick plug-and-play structures are provided at both ends of the conduit 13. The quick plug-and-play structure includes a base 131, a connecting pipe 132, a hemispherical convex block 133, an air cushion ring 134, and a movable clamping block 135. The connecting pipe 132 is fixed to one end of the conduit 13 through the base 131 and is in communication with the inside of the conduit 13. The hemispherical convex block 133 is fixed to the top end of the connecting pipe 132, and the top end opening of the connecting pipe 132 extends to the upper end surface of the hemispherical convex block 133. An annular air cushion ring 134 is nested at the bottom edge of the hemispherical convex block 133. The movable clamping block 135 is a frustum-shaped structure symmetric up and down. The maximum outer diameter of the movable clamping block 135 is greater than or equal to the maximum outer diameter of the hemispherical convex block 133. The movable clamping block 135 is slidably sleeved on the connecting pipe 132, and the movable clamping block 135 is located between the hemispherical convex block 133 and the base 131; One end of the manifold 12 and one end of the air outlet pipe of the blower 1 are both fixed with quick connectors 14. The quick connectors 14 are used in conjunction with a quick plugging and unplugging structure for quickly plugging and unplugging the conduit 13. The quick connector 14 is a cylindrical structure with through holes at both ends. One end of the connecting pipe 132 is inserted into the cavity inside the quick connector 14, and the hemispherical convex block 133 is slidably clamped in the cavity inside the quick connector 14. The shape of the hemispherical convex block 133 is adapted to the inner cavity of the quick connector 14. The air cushion ring 134 is used to seal the gap between the hemispherical convex block 133 and the inner cavity of the quick connector 14 to prevent air leakage; On the inner walls of both sides at the lower end of the quick connector 14, guiding grooves 141 are provided. In both of the two guiding grooves 141, guiding rods 143 are slidably connected. One end of each of the two guiding rods 143 slidably penetrates through the inner wall of the corresponding side of the quick connector 14 and extends to the outside of the quick connector 14. On the ends of the two guiding rods 143 facing the axis of the quick connector 14, clamping blocks 142 are fixed. The two clamping blocks 142 are respectively slidably connected in the corresponding guiding grooves 141, and in the natural state, one end of each of the two clamping blocks 142 is located in the inner cavity of the quick connector 14. Second springs 144 are sleeved on the two guiding rods 143, and the two ends of the two second springs 144 are respectively connected and fixed to the clamping block 142 and the inner wall on one side of the guiding groove 141 corresponding to the side; In this embodiment, the side of the clamping block 142 facing the axis of the quick connector 14 is inclined inward to form a slope. When the conduit 13 is docked with the quick connector 14, the connecting pipe 132 is first inserted into the inner cavity of the quick connector 14. When the hemispherical convex block 133 at the top of the connecting pipe 132 moves inward into the quick connector 14, it will gradually contact the clamping block 142. The convex part of the hemispherical convex block 133 cooperates with the inclined surface on one side of the clamping block 142 to gradually push the clamping block 142 inward. When the clamping block 142 moves inward, it compresses the second spring 144. When the hemispherical convex block 133 moves above the clamping block 142, the two are separated, and the clamping block 142 is no longer squeezed and gradually resets under the action of the second spring 144. After the clamping block 142 resets, its top will abut against the bottom of the hemispherical convex block 133 to support the hemispherical convex block 133, thereby fixing the connecting pipe 132 in the inner cavity of the quick connector 14; When it is necessary to separate the catheter 13 from the quick connector 14, the catheter 13 can be continuously inserted into the quick connector 14. During the insertion process, the clamping block 142 contacts the movable clamping block 135. Under the cooperation of the slopes of the two, the clamping block 142 moves inward and presses the second spring 144. When the movable clamping block 135 continuously moves upward to the upper side of the clamping block 142, the two are separated, and the clamping block 142 resets under the action of the spring. At this time, the clamping block 142 is located at the bottom of the movable clamping block 135 and supports the movable clamping block 135. Then, the catheter 13 is pulled backward, and the movable clamping block 135 slides and sleeves on the connecting pipe 132. During the process of pulling the catheter 13, under the supporting action of the clamping block 142, the movable clamping block 135 will slide upward along the connecting pipe 132 until the top end of the movable clamping block 135 abuts against the bottom of the hemispherical convex block 133. At this time, the movable clamping block 135 can no longer slide. Subsequently, the catheter 13 is pulled downward again. The inclined surface at the lower end of the movable clamping block 135 cooperates with the slope surface of the clamping block 142 to push the clamping block 142 inward, and the clamping block 142 contracts in the guiding groove 141. As the catheter 13 is continuously pulled, one end of the clamping block 142 gradually slides over the surfaces of the movable clamping block 135 and the hemispherical convex block 133 until it detaches from the top of the hemispherical convex block 133. At this time, the connecting pipe 132 can be pulled out from the inner cavity of the quick connector 14, and the catheter 13 is separated from the quick connector 14.

[0040] Please refer to Figure 4 、 Figure 13 、 Figure 14 and Figure 15 . The self-locking structures 51 are provided in multiple numbers, and the multiple self-locking structures 51 are arranged at equal intervals around the outer periphery of the connecting cylinder 5. Positioning holes 67 are formed in the inner wall of the outer cylinder 61 corresponding to one side of the multiple self-locking structures 51. The self-locking structure 51 includes a positioning cylinder 511, a positioning rod 512, a locking column 513, a first spring 514, and a wrench 515. The positioning cylinder 511 is embedded and fixed in the inner wall of the connecting cylinder 5, and the top end of the positioning cylinder 511 extends to the outer surface of the connecting cylinder 5. The positioning rod 512 is slidably connected in the positioning cylinder 511. The locking column 513 is fixed to the bottom end of the positioning rod 512, and the bottom end of the locking column 513 is inserted into the corresponding positioning hole 67 on one side. The outer diameter of the locking column 513 is smaller than the inner diameter of the positioning cylinder 511. The locking column 513 extends into the inner cavity of the connecting cylinder 5 in the natural state. A first spring 514 is sleeved on the positioning rod 512, and the upper and lower ends of the first spring 514 are respectively connected and fixed to the inner wall of the top of the positioning cylinder 511 and the top of the locking column 513. The wrench 515 is rotatably connected to the top end of the positioning rod 512, and the wrench 515 is located above the positioning cylinder 511. The side surface of the wrench 515 is an arc surface for reducing the frictional resistance; In this embodiment, when it is necessary to dock and assemble the connecting cylinder 5 with the heat dissipation mechanism 6, the connecting cylinder 5 can be directly aligned and sleeved on the outer cylinder 61. The locking column 513 contracts inward under the resistance of the outer wall of the outer cylinder 61 and compresses the first spring 514. When one end of the locking column 513 is inserted into the positioning hole 67, the locking column 513 is no longer squeezed, and the first spring 514 will drive the locking column 513 to reset, so that it is clamped in the positioning hole 67. At this time, the connecting cylinder 5 and the heat dissipation mechanism 6 are docked and fixed. When it is necessary to disassemble the connecting cylinder 5, the wrench 515 can be rotated upward. The side surface of the wrench 515 is an arc surface. When the wrench 515 is rotated upward by 90 degrees, its arc-shaped side surface abuts against the top end of the positioning cylinder 511. The top end of the positioning rod 512 is rotatably connected to the middle of the wrench 515. During the rotation process, the side wall of the wrench 515 abuts against the positioning cylinder 511 to generate pressure. Under the action of the pressure, the wrench 515 will pull the positioning rod 512 upward and synchronously pull the locking column 513 upward, so that the locking column 513 contracts in the positioning cylinder 511. At this time, one end of the locking column 513 disengages from the positioning hole 67, and the locking column 513 no longer locks the outer cylinder 61. The connecting cylinder 5 can be directly pulled out from the outer cylinder 61. Through the self-locking structure 51, the connecting cylinder 5 and the heat dissipation mechanism 6 can be disassembled and assembled conveniently and quickly, which is convenient for users to repair and maintain the heat dissipation mechanism 6.
