Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of generator set, and particularly relates to a generator set with a fault self-checking function. BACKGROUND

[0002] As a complete mechanical equipment for converting other forms of energy into electric energy, the generator set plays an indispensable role in various fields in today's society. Whether it is power supply for large equipment in industrial production, normal operation of commercial places, or power supply in special scenarios such as outdoor construction and emergency rescue, the generator set has become an important choice for power supply due to its flexibility and reliability.

[0003] With the continuous progress of science and technology, the technology of the generator set is also continuously innovating. From the early simple mechanical structure to the complex system integrating various advanced technologies today, the performance and function of the generator set have been significantly improved. Among them, the generator set with a fault self-checking function has become an important direction in recent years. Such a generator set can monitor its own running state in real time, and through the built-in sensor and intelligent control system, it can give an early warning and diagnosis for possible faults, greatly improving the reliability and maintenance efficiency of the generator set and reducing the power loss caused by sudden faults.

[0004] During the operation of the generator set, a large amount of heat will be generated in the machine box. If the high-temperature area in the machine box cannot be effectively cooled, it will have a serious impact on the performance and service life of the generator set. First, high temperature will accelerate the wear and aging of the internal parts of the engine, reducing the reliability and service life of the engine.

[0005] During the operation of the generator set, different degrees of vibration will be generated. For the generator set itself, long-term vibration will cause loosening, wear and fatigue damage of the parts, reducing the reliability and service life of the generator set. Strong vibration may also cause damage to surrounding buildings and equipment. SUMMARY

[0006] The purpose of the present application is to provide a generator set with a fault self-checking function to solve the problems in the prior art.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical scheme:

[0008] The generator set with a fault self-checking function comprises a machine box, a generator set, a damping unit and a heat dissipation unit. The machine box is placed on a horizontal ground. The generator set and the damping unit are fixedly connected. The damping unit has the function of reducing vibration generated during the operation of the generator set. The damping unit and the heat dissipation unit are fixedly connected. The heat dissipation unit has the function of reducing the temperature in the machine box.

[0009] The cabinet is used for mounting and fixing the generator set, the damping unit and the heat dissipation unit. The generator set is used for providing power. The damping unit is used for reducing the vibration generated when the generator set works. The heat dissipation unit is used for discharging the heat generated when the generator set works, so as to realize cooling. When the generator set works in the cabinet, the vibration generated by the generator set is reduced by the damping unit, so as to avoid damaging or loosening the parts of the generator set. The heat generated by the generator set is discharged from the cabinet in time by the heat dissipation unit, so as to avoid high temperature causing failure of the generator set.

[0010] Further, the damping unit comprises a supporting plate, a striking rod, a quartz block, a fixing cylinder, a sliding groove, a guide column and a folding plate. The supporting plate is fixedly connected with the generator set. The supporting plate is fixedly connected with the striking rod. The striking rod is slidingly connected with the fixing cylinder. The quartz block is fixedly installed in the fixing cylinder. The fixing cylinder is fixedly installed in the cabinet. The sliding groove is fixedly installed in the cabinet. One end of the guide column is fixedly connected with the fixing cylinder. The other end of the guide column is slidingly connected with the folding plate. The folding plate is slidingly installed in the sliding groove.

[0011] Further, the damping unit further comprises a damping spring, a push rod, a first electromagnet, a second electromagnet, a sliding magnet, a fixing box and a straight rod. One end of the damping spring is fixedly connected with the folding plate. The other end of the damping spring is fixedly connected with the sliding groove. One end of the push rod is fixedly connected with the lower surface of the supporting plate. The other end of the push rod is fixedly connected with the sliding magnet. The push rod is slidingly connected with the first electromagnet. The first electromagnet is fixedly installed in the upper end of the fixing box. The second electromagnet is fixedly installed in the lower end of the fixing box. The sliding magnet is slidingly installed in the fixing box. The fixing box is fixedly installed in the cabinet. One end of the straight rod is rotatably connected with the striking rod. The other end of the straight rod is rotatably connected with the folding plate. The folding plate is electrically connected with the first electromagnet. The folding plate is electrically connected with the second electromagnet.

[0012] When the generator set is working, it produces up and down shaking. When the generator set moves downward, on the one hand, the bracket pushes the push rod to drive the sliding magnet to move downward along the fixed box, and on the other hand, the bracket pushes the impact rod to move downward along the fixed cylinder and hit the quartz block to generate current which is detected by the controller. When the current generated by the quartz block is detected to flow into the controller, the controller changes the current direction flowing into the drive coil. The current flows into the drive coil from the left end of the guide column. When the impact rod pushes the straight rod, the straight rod pushes the folding plate to move leftward along the chute and squeeze the damping spring to reduce the vibration. At this time, the folding plate moves leftward along the guide column, the effective number of turns of the drive coil is reduced, the resistance is reduced, and thus the current flowing into the second electromagnet through the folding plate is gradually increased, so that the second electromagnet is electrified to have the same polarity as the sliding magnet, thereby resisting the sliding magnet moving downward and reducing the moving distance of the sliding magnet to reduce the vibration of the generator set. When the generator set moves upward, on the one hand, the bracket drives the push rod and the sliding magnet to move upward along the fixed box, and on the other hand, the bracket drives the impact rod to move upward along the fixed cylinder. At this time, the impact rod no longer hits the quartz block, and the controller restores the current direction flowing into the drive coil. The current flows into the drive coil from the right end of the guide column. When the impact rod pulls the straight rod upward, the straight rod pushes the folding plate to move rightward along the chute under the action of the restoring force of the damping spring. At this time, the folding plate slides rightward along the guide column. At this time, the effective number of turns of the drive coil is reduced, the resistance is reduced, and thus the current flowing into the first electromagnet through the folding plate is gradually increased, so that the first electromagnet is electrified to have the same polarity as the sliding magnet, thereby resisting the sliding magnet moving upward and reducing the moving distance of the sliding magnet to reduce the vibration of the generator set, protect the generator set and improve the service life of the generator set.

[0013] Further, the heat dissipation unit comprises an upper rack, a gear, a bent rod, a lower rack, a vacuum box and a push plate. The upper rack is fixedly connected with the folding plate. The upper rack is in meshing connection with the gear. The gear is in rotary connection with one end of the bent rod. The other end of the bent rod is fixedly connected with the case. The gear is in meshing connection with the lower rack. The vacuum box is fixedly connected with the case. The push plate is slidably installed in the vacuum box.

[0014] Further, the heat dissipation unit further comprises a gas supply pipe, an exhaust pipe, a straight pipe, a first fixed ring, a second fixed ring and a squeezing block. One end of the gas supply pipe is in conductive connection with the vacuum box. The gas supply pipe is in conductive connection with the exhaust pipe. The exhaust pipe is fixedly installed in the case. The straight pipe is in conductive connection with the exhaust pipe. The straight pipe comprises two hard pipes at the two ends and an elastic pipe at the middle. The first fixed ring is fixedly installed at the hard pipe of the straight pipe. The second fixed ring is fixedly installed at the hard pipe of the straight pipe. The squeezing block is slidably installed between the first fixed ring and the second fixed ring.

[0015] Further, the heat dissipation unit further comprises an elastic contraction ring, a pull rope, a circular plate, a memory spring, a fixed rod and a sliding plate, one end of the elastic contraction ring is fixedly connected with the extrusion block, one end of the pull rope is fixedly connected with the extrusion block, the other end of the pull rope penetrates through the straight pipe and is fixedly connected with the circular plate, one end of the memory spring is fixedly connected with the circular plate, the other end of the memory spring is fixedly connected with the fixed rod, the fixed rod is fixedly connected with the straight pipe, one end of the sliding plate is fixedly connected with the lower rack, the other end of the sliding plate is fixedly connected with the push plate, and the sliding plate is slidably connected with the vacuum box.

[0016] When the folding plate moves to the left, the upper rack driving gear rotates counterclockwise around the bent rod, and the gear drives the lower rack to move to the right, at this time, the rack drives the sliding plate to pull the push plate to move to the right, extruding the high-temperature gas in the second chamber of the vacuum box from the one-way air outlet valve, while the first chamber inhales external air from the one-way air inlet valve. When the folding plate moves to the right, the upper rack driving gear rotates clockwise around the bent rod, and the gear drives the lower rack to move to the left, at this time, the rack drives the sliding plate to push the push plate to move to the left, extruding the gas in the first chamber of the vacuum box from the one-way air outlet valve into the air supply pipe, while the second chamber inhales the high-temperature gas inside the box from the one-way air inlet valve. The gas in the air supply pipe is transported to the straight pipe through the exhaust pipe and discharged into the box for heat exchange, thereby generating high temperature for the generator set working in the box to dissipate heat. Because the heat generated in different areas of the generator set is different, when the temperature in the high-temperature area is too high, the memory spring shrinks due to heat, thereby pulling the circular plate to drive the pull rope, so that the extrusion block moves along the first fixed ring and the second fixed ring, extruding the straight pipe elastic tube, so that the flow diameter of the straight pipe elastic tube becomes smaller. Under the condition that the flow rate in the exhaust pipe remains unchanged, the diameter of the straight pipe elastic tube through which the gas flows becomes smaller, thereby increasing the flow rate of the gas and accelerating the heat exchange in the high-temperature area, thereby further improving the heat exchange rate in the high-temperature area of the box.

[0017] Further, the number of teeth of the upper rack and the lower rack is 3:1-9:1.

[0018] In order to convert the vertical displacement of the shock-absorbed back plate into a small displacement of the upper rack through the transmission of the straight rod, and then into a large displacement of the lower rack under the transmission of the gear, it is convenient for the sliding plate to push the push plate to inhale sufficient air from the outside or sufficient high-temperature gas from the box, and to perform heat exchange in the box during the left and right movement of the push plate, thereby improving the heat dissipation efficiency.

[0019] Further, a driving coil is arranged on the guide column, and a conductive ring is arranged on the contact end of the folding plate and the guide column.

[0020] In order to facilitate the control of the power supply of the first electromagnet and the second electromagnet to suppress the movement amplitude of the sliding magnet, thereby reducing the vibration amplitude of the generator set, protecting the generator set from damage to its own structure or parts, and improving the service life.

[0021] Further, the push plate divides the vacuum box into a first chamber and a second chamber, and the first chamber and the second chamber are provided with one-way air inlet valves and one-way air outlet valves.

[0022] In order to facilitate the push plate to inhale and discharge gas during left and right sliding in the vacuum box, and provide conditions for heat dissipation inside the case.

[0023] Further, the case is provided with a controller, and the generator set is provided with an ultrasonic analyzer.

[0024] When the bearing of the generator set fails, periodic impact vibration is generated, high-frequency ultrasonic waves are excited, and the ultrasonic analyzer is used for collection and analysis, so that the signal is transmitted to the controller for alarm, and the process of self-checking of the engine set fault is realized.

The damping unit 3 is used for reducing the vibration generated when the generator set 2 works. The heat dissipation unit 4 is used for discharging the heat generated when the generator set 2 works in the cabinet 1, so as to realize cooling. When the generator set 2 works in the cabinet 1, the vibration generated by the generator set 2 is reduced by the damping unit 3, so as to avoid damaging or loosening the parts of the generator set 2. The heat generated by the generator set 2 is discharged from the cabinet 1 in time by the heat dissipation unit 4, so as to avoid causing the generator set 2 to malfunction due to high temperature.

[0042] As shown in Figure 6 , Figure 8 , the damping unit 3 comprises a supporting plate 31, a striking rod 32, a quartz block 33, a fixing cylinder 34, a sliding groove 35, a guide column 36 and a folding plate 37. The supporting plate 31 is fixedly connected with the generator set 2. The supporting plate 31 is fixedly connected with the striking rod 32. The striking rod 32 is slidingly connected with the fixing cylinder 34. The quartz block 33 is fixedly installed in the fixing cylinder 34. The fixing cylinder 34 is fixedly installed in the cabinet 1. The sliding groove 35 is fixedly installed in the cabinet 1. One end of the guide column 36 is fixedly connected with the fixing cylinder 34. The other end of the guide column 36 is slidingly connected with the folding plate 37. The folding plate 37 is slidingly installed in the sliding groove 35.

[0043] As shown in Figure 5 , Figure 6 , Figure 8 , the damping unit 3 further comprises a damping spring 38, a pushing rod 39, a first electromagnet 310, a second electromagnet 311, a sliding magnet 312, a fixing box 313 and a straight rod 314. One end of the damping spring 38 is fixedly connected with the folding plate 37. The other end of the damping spring 38 is fixedly connected with the sliding groove 35. One end of the pushing rod 39 is fixedly connected with the lower surface of the supporting plate 31. The other end of the pushing rod 39 is fixedly connected with the sliding magnet 312. The pushing rod 39 is slidingly connected with the first electromagnet 310. The first electromagnet 310 is fixedly installed in the upper end of the fixing box 313. The second electromagnet 311 is fixedly installed in the lower end of the fixing box 313. The sliding magnet 312 is slidingly installed in the fixing box 313.

The folding plate 37 is electrically connected with the second electromagnet 311.

[0044] When the generator set 2 is working, the up-and-down shaking is generated. When the generator set 2 moves downward, on the one hand, the bracket 31 pushes the push rod 39 to drive the sliding magnet 312 to move downward along the fixed box 313, and on the other hand, the bracket 31 pushes the impact rod 32 to move downward along the fixed cylinder 34 and impact the quartz block 33, so as to generate the electric current which is detected by the controller. When the electric current generated by the quartz block 33 is detected to pass into the controller, the controller changes the direction of the electric current passing into the driving coil, and the electric current is passed into the driving coil from the left end of the guide column 36. When the impact rod 32 pushes the straight rod 314, the straight rod 314 pushes the folding plate 37 to move leftward along the sliding groove 35 and compresses the damping spring 38 to perform damping.

When the generator set 2 moves upward, on the one hand, the bracket 31 drives the push rod 39 and the sliding magnet 312 to move upward along the fixed box 313, and on the other hand, the bracket 31 drives the impact rod 32 to move upward along the fixed cylinder 34. At this time, the impact rod 32 no longer impacts the quartz block 33, the controller restores the direction of the electric current passing into the driving coil, and the electric current is passed into the driving coil from the right end of the guide column 36. When the impact rod 32 pulls the straight rod 314 upward, the straight rod 314 pushes the folding plate 37 to move rightward along the sliding groove 35 under the action of the self-restoring force of the damping spring 38. At this time, the folding plate 37 slides rightward along the guide column 36. At this time, the effective number of turns of the driving coil is reduced, the resistance is reduced, the electric current passing through the folding plate 37 and flowing into the first electromagnet 310 is gradually increased, the first electromagnet 310 is electrified to present the same polarity as the sliding magnet 312, so as to resist the sliding magnet 312 moving upward, reduce the moving distance of the sliding magnet 312, and jointly reduce the shaking of the generator set 2, so as to protect the generator set 2 and improve the service life of the generator set 2.

[0045] As shown in Figure 3 , Figure 5 , Figure 7 , Figure 8 , the heat dissipation unit 4 comprises an upper rack 41, a gear 42, a bent rod 43, a lower rack 44, a vacuum box 45 and a push plate 46. The upper rack 41 is fixedly connected with the folding plate 37, the upper rack 41 is in meshing connection with the gear 42, the gear 42 is in rotary connection with one end of the bent rod 43, the other end of the bent rod 43 is fixedly connected with the case 1, the gear 42 is in meshing connection with the lower rack 44, the vacuum box 45 is fixedly connected with the case 1, and the push plate 46 is slidingly installed in the vacuum box 45.

[0046] As shown in Figure 2 , Figure 9As shown in the figure, the heat dissipation unit 4 further comprises a gas feeding pipe 47, an exhaust pipe 48, a straight pipe 49, a first fixing ring 410, a second fixing ring 411 and a pressing block 412. One end of the gas feeding pipe 47 is in communication with the vacuum box 45, the gas feeding pipe 47 is in communication with the exhaust pipe 48, the exhaust pipe 48 is fixedly installed in the case 1, the straight pipe 49 is in communication with the exhaust pipe 48, the straight pipe 49 is composed of a hard pipe at both ends and an elastic pipe in the middle, the first fixing ring 410 is fixedly installed at the hard pipe of the straight pipe 49, the second fixing ring 411 is fixedly installed at the hard pipe of the straight pipe 49, and the pressing block 412 is slidingly installed between the first fixing ring 410 and the second fixing ring 411.

[0047] As shown in the figure, Figure 5 , Figure 7 , Figure 9 As shown in the figure, the heat dissipation unit 4 further comprises an elastic contraction ring 413, a pull rope 414, a circular plate 415, a memory spring 416, a fixing rod 417 and a sliding plate 418. The elastic contraction ring 413 is fixedly connected with the pressing block 412, one end of the pull rope 414 is fixedly connected with the pressing block 412, the other end of the pull rope 414 penetrates through the straight pipe 49 and is fixedly connected with the circular plate 415, one end of the memory spring 416 is fixedly connected with the circular plate 415, the other end of the memory spring 416 is fixedly connected with the fixing rod 417, the fixing rod 417 is fixedly connected with the straight pipe 49, one end of the sliding plate 418 is fixedly connected with the lower rack 44, the other end of the sliding plate 418 is fixedly connected with the push plate 46, and the sliding plate 418 is slidingly connected with the vacuum box 45.

[0048] When the foldable plate 37 moves to the left, the upper rack 41 drives the gear 42 to rotate anticlockwise around the bent rod 43, and the gear 42 drives the lower rack 44 to move to the right, at this time, the rack drives the sliding plate 418 to pull the push plate 46 to move to the right, and the high-temperature gas in the second chamber of the vacuum box 45 is discharged from the one-way air outlet valve, while the outside air is sucked into the first chamber from the one-way air inlet valve. When the foldable plate 37 moves to the right, the upper rack 41 drives the gear 42 to rotate clockwise around the bent rod 43, and the gear 42 drives the lower rack 44 to move to the left, at this time, the rack drives the sliding plate 418 to push the push plate 46 to move to the left, and the gas in the first chamber of the vacuum box 45 is delivered to the air supply pipe 47 from the one-way air outlet valve, while the high-temperature gas in the second chamber is sucked into the machine box 1 from the one-way air inlet valve. The gas in the air supply pipe 47 is delivered to the straight pipe 49 through the exhaust pipe 48 and discharged into the machine box 1 for heat exchange, thereby providing heat dissipation for the generator set 2 working in the machine box 1. Due to the different heat generated in different areas of the generator set 2, when the temperature in the high-temperature area is too high, the memory spring 416 shrinks, thereby pulling the round plate 415 to drive the pull rope 414, moving the extrusion block 412 along the first fixed ring 410 and the second fixed ring 411, extruding the elastic pipe of the straight pipe 49, and reducing the flow diameter of the elastic pipe of the straight pipe 49. Under the condition that the flow rate in the exhaust pipe 48 remains unchanged, the diameter of the elastic pipe of the straight pipe 49 decreases, thereby increasing the flow rate of the gas and accelerating the heat exchange in the high-temperature area, thereby further improving the heat exchange rate in the high-temperature area of the machine box 1.

[0049] As shown in Figure 8 The tooth number ratio of the upper rack 41 to the lower rack 44 is 3:1-9:1.

[0050] In order to convert the vertical displacement of the shock-absorbed back plate 31 into a small displacement of the upper rack 41 through the transmission of the straight rod 314, and then into a large displacement of the lower rack 44 under the transmission of the gear 42, it is convenient for the sliding plate 418 to push the push plate 46 to suck in sufficient air from the outside or sufficient high-temperature gas from the machine box 1, and to heat exchange in the machine box 1 during the left and right movement of the push plate 46, thereby improving the heat dissipation efficiency.

[0051] As shown in Figure 6 The guide column 36 is provided with a driving coil, and the contact end of the foldable plate 37 is provided with a conductive ring.

[0052] In order to facilitate the control of the first electromagnet 310 and the second electromagnet 311 to suppress the movement amplitude of the sliding magnet 312, thereby reducing the vibration amplitude of the generator set 2, protecting the generator set 2 from damage to its own structure or parts, and improving the service life.

[0053] As shown in Figure 5As shown, the push plate 46 divides the vacuum box 45 into a first chamber and a second chamber, both of which are provided with one-way air inlet valves and one-way air outlet valves.

[0054] In order to facilitate the push plate 46 to inhale and discharge gas during left and right sliding in the vacuum box 45, and provide conditions for heat dissipation inside the machine box 1.

[0055] As shown, Figure 1 The machine box 1 is provided with a controller, and the generator set 2 is provided with an ultrasonic analyzer.

[0056] When the bearing wear fault of the generator set 2 occurs, periodic impact vibration is generated, high-frequency ultrasonic waves are excited, and the ultrasonic analyzer is used for collection and analysis, so that the signal is transmitted to the controller, an alarm is given, and the process of self-checking of the engine set fault is realized.

[0057] The working principle of the present application is as follows:

[0058] When the generator set 2 is working, it will produce up and down shaking. When the generator set 2 moves downward, on one hand, the bracket 31 pushes the push rod 39 to drive the sliding magnet 312 to move downward along the fixed box 313, on the other hand, the bracket 31 pushes the impact rod 32 to move downward along the fixed cylinder 34 and impact the quartz block 33 to generate electric current which is detected by the controller. When the electric current generated by the quartz block 33 is detected to pass into the controller, the controller changes the direction of the electric current passing into the driving coil, starting from the driving coil at the left end of the guide column 36, when the impact rod 32 pushes the straight rod 314, so that the straight rod 314 pushes the folding plate 37 to move leftward along the sliding groove 35 and compresses the damping spring 38 to reduce the damping. At this time, the folding plate 37 moves leftward along the guide column 36, the effective number of turns of the driving coil is reduced, the resistance is reduced, so that the electric current flowing into the second electromagnet 311 through the folding plate 37 is gradually increased, the second electromagnet 311 is electrified to have the same polarity as the sliding magnet 312, so as to resist the sliding magnet 312 moving downward, reduce the moving distance of the sliding magnet 312, and reduce the shaking of the generator set 2. When the generator set 2 moves upward, on one hand, the bracket 31 drives the push rod 39 and the sliding magnet 312 to move upward along the fixed box 313, on the other hand, the bracket 31 drives the impact rod 32 to move upward along the fixed cylinder 34. At this time, the impact rod 32 no longer impacts the quartz block 33, the controller restores the direction of the electric current passing into the driving coil, starting from the driving coil at the right end of the guide column 36, when the impact rod 32 pulls the straight rod 314 upward, cooperating with the restoring force of the damping spring 38, the straight rod 314 pushes the folding plate 37 to move rightward along the sliding groove 35. At this time, the folding plate 37 slides rightward along the guide column 36. At this time, the effective number of turns of the driving coil is reduced, the resistance is reduced, so that the electric current flowing into the first electromagnet 310 through the folding plate 37 is gradually increased, the first electromagnet 310 is electrified to have the same polarity as the sliding magnet 312, so as to resist the sliding magnet 312 moving upward, reduce the moving distance of the sliding magnet 312, and reduce the shaking of the generator set 2 together, protect the generator set 2, and improve the service life of the generator set 2.

[0059] When the fold plate 37 moves to the left, the upper rack 41 drives the gear 42 to rotate anticlockwise around the bent pole 43, and the gear 42 drives the lower rack 44 to move to the right, at this time, the rack drives the sliding plate 418 to pull the push plate 46 to move to the right, extruding the high-temperature gas in the second chamber of the vacuum box 45 to discharge from the one-way air outlet valve, while the outside air is sucked into the first chamber from the one-way air inlet valve. When the fold plate 37 moves to the right, the upper rack 41 drives the gear 42 to rotate clockwise around the bent pole 43, and the gear 42 drives the lower rack 44 to move to the left, at this time, the rack drives the sliding plate 418 to push the push plate 46 to move to the left, extruding the gas in the first chamber of the vacuum box 45 to be delivered to the air supply pipe 47 from the one-way air outlet valve, while the high-temperature gas in the second chamber is sucked into the inside of the case 1 from the one-way air inlet valve. The gas in the air supply pipe 47 is delivered to the straight pipe 49 through the exhaust pipe 48 and discharged into the inside of the case 1 for heat exchange, thereby generating high temperature for the generator set 2 working inside the case 1 to dissipate heat. Since the heat generated in different areas of the generator set 2 is different, when the temperature in the high-temperature area is too high, the memory spring 416 shrinks under the heat, thereby pulling the round plate 415 to drive the pull rope 414, making the extrusion block 412 move along the first fixed ring 410 and the second fixed ring 411, extruding the elastic pipe of the straight pipe 49, so that the flow diameter of the elastic pipe of the straight pipe 49 becomes smaller. Under the condition that the flow rate in the exhaust pipe 48 is unchanged, the diameter of the elastic pipe of the straight pipe 49 becomes smaller, thereby increasing the flow rate of the gas and accelerating the heat exchange in the high-temperature area, thereby further improving the heat exchange rate of the high-temperature area in the case 1.
