The heat hood is installed at one end of the casing, the heat dissipation hood is connected to the casing, the heat dissipation hood is covered with a heat dissipation fan, and the heat dissipation hood is provided with an air outlet.

DETAILED DESCRIPTION

[0030] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0031] Example 1: Reference Figure 1-Figure 5A magnetic suspension centrifugal compressor with high heat dissipation comprises a compressor body 1, a cooling cylinder 3 is fixedly connected to the outer wall of the middle part of the compressor body 1, and there is a gap between the middle part of the cooling cylinder 3 and the compressor body 1, a sliding cavity 13 is arranged inside the cooling cylinder 3, and a gas collecting cavity 12 is arranged on one side of the sliding cavity 13, and an exhaust cavity 16 is arranged on the other side of the sliding cavity 13, and a plurality of one-way ventilation pipes 6 are arranged between the opposite outer walls of the gas collecting cavity 12 and the exhaust cavity 16, and the plurality of one-way ventilation pipes 6 are equidistantly distributed on the outer wall of the cooling cylinder 3 with the center of the cooling cylinder 3 as the center, and the gas collecting cavity 12 is arranged on the outer wall of the cooling cylinder 3. The air cavity 12 is sealed and fixedly connected with an annular sealing plate 11, and the annular sealing plate 11 divides the air collecting cavity 12 into two parts. The outer wall of the air collecting cavity 12 on one side away from the sliding cavity 13 is equidistantly provided with a plurality of one-way air inlet valves 2, and a ring-shaped flow pipe 7 is provided inside the air collecting cavity 12. The outer wall of the exhaust cavity 16 on one side away from the sliding cavity 13 is inlaid with two electric push rods 15, and the outer wall of the exhaust cavity 16 on one side away from the sliding cavity 13 is provided with a one-way exhaust valve 5. The telescopic ends of the two electric push rods 15 are fixedly connected with an annular piston plate 14, and the annular piston plate 14 seals the sliding cavity 13. The compressor body 1 is dynamically connected to the inner wall of the sliding cavity 13, and the outer wall of the annular sealing plate 11 is equidistantly provided with a plurality of trumpet holes 10, and the wide openings of the trumpet holes 10 are all oriented toward the center of the annular sealing plate 11, and a one-way sealing mechanism is provided inside the wide openings of the trumpet holes 10, and a liquid storage tank 4 is provided at one end of the annular flow pipe 7, and the other end of the flow pipe 7 passes through the cooling cylinder 3 and is provided on the outer wall of the top of the liquid storage tank 4, and a flow mechanism is provided on the top of the liquid storage tank 4. When the compressor body 1 is running, the two electric push rods 15 on the outer wall of the exhaust cavity 16 are started at the same time, so that the two electric push rods 15 can push the sliding cavity 13 The annular piston plate 14 in the air collecting chamber 12 moves back and forth. When the annular piston plate 14 moves toward the exhaust chamber 16, the gas in the annular piston plate 14 is squeezed. At the same time, the external gas can be absorbed through multiple one-way intake valves 2 and sucked into the gas collecting chamber 12. Because the one-way ventilation pipe 6 can only allow the gas in the gas collecting chamber 12 to flow into the exhaust chamber 16, the gas in the exhaust chamber 16 can be discharged through the one-way exhaust valve 5, and at the same time, part of the gas can start the flow mechanism on the liquid storage tank 4, so that the coolant in the liquid storage tank 4 can flow in the flow pipe 7. Thereby, the gas entering into the gas collecting chamber 12 is cooled, and when the annular piston plate 14 moves toward the gas collecting chamber 12, the gas in the gas collecting chamber 12 can be squeezed, and as the annular piston plate 14 continues to move, the compressed gas can push open the one-way sealing mechanism in the trumpet hole 10, so that the gas can enter into the space between the annular sealing plate 11 and the bottom of the gas collecting chamber 12 through the trumpet hole 10, and then enter into multiple one-way ventilation pipes 6, and flow into the exhaust chamber 16 from the multiple one-way ventilation pipes 6. Such a cycle can make the cooled airflow flow continuously on the surface of the compressor body 1, and can quickly take away the heat generated by the compressor body 1 during operation, thereby greatly improving the heat dissipation effect of the compressor body 1.

[0032] As a further scheme in the present invention, the flow mechanism includes an air collecting cylinder 8, which is sealed and embedded in the top of the liquid storage tank 4, and the bottom of the air collecting cylinder 8 is sealed and slidably connected with a telescopic rod 25, the top of the telescopic rod 25 is fixedly connected with a piston plate 23, and the piston plate 23 is sealed and slidably connected to the inner wall of the air collecting cylinder 8, the piston plate 23 and the inner wall of the top of the air collecting cylinder 8 are fixedly connected with a connecting spring 24, and the top of the air collecting cylinder 8 and the exhaust chamber 16 are connected with an intake pipe 9. When the annular piston plate 14 moves toward the exhaust chamber 16, part of the gas in the exhaust chamber 16 will enter the air collecting cylinder 8 through the intake pipe 9. As the amount of gas entering increases, the piston plate 23 can be pushed to move downward, and when the annular piston plate 14 moves toward the air collecting chamber 12, the gas in the air collecting cylinder 8 can be extracted, so that under the action of the rebound force of the connecting spring 24, the piston plate 23 can be reset, and such a cycle can enable the piston plate 23 to push the telescopic rod 25 at the bottom of the air collecting cylinder 8 to reciprocate.

[0033] As a further solution of the present invention, the bottom end of the telescopic rod 25 is fixedly connected to a piston plate 21, and two through holes 22 are provided on the top of the piston plate 21, and a mounting cavity 26 is provided on both sides of each through hole 22, and the mounting cavity 26 is provided on the bottom outer wall of the piston plate 21, and a connecting spring 3 27 is fixedly connected inside the mounting cavity 26, and the bottom ends of the two connecting springs 3 27 on the same side are fixedly connected to a sealing plate 28, and the sealing plate 28 seals the corresponding through hole 22, so that the piston plate 21 moves back and forth up and down in the liquid storage tank 4. When the plate 1 21 moves downward, the sealing plate 28 seals the through hole 22, so that the piston plate 1 21 can squeeze the coolant below it into the flow tube 7, so that the coolant in the flow tube 7 flows, and the coolant in the flow tube 7 enters the space above the piston plate 1 21. When the piston plate 1 21 moves upward, the sealing plate 28 can be pushed open under the action of pressure, so that the through hole 22 is opened, and the coolant can flow downward through the through hole 22, so that the coolant on the piston plate 1 21 can enter the space below the piston plate 1 21 through the through hole 22. Thus, the coolant can flow continuously in the flow tube 7.

[0034] As a further scheme in the present invention, the one-way sealing mechanism includes a mounting tube 17, which is embedded in the inner wall of the air collecting chamber 12, and a slide rod 19 is slidably connected to the top of the mounting tube 17, a connecting spring 20 is fixedly connected between the bottom end of the slide rod 19 and the bottom inner wall of the mounting tube 17, and a sealing ball 18 is fixedly connected to the top of the slide rod 19, the sealing ball 18 is located in the wide mouth of the corresponding horn hole 10 and seals the horn hole 10, when the annular piston plate 14 moves toward the air collecting chamber 12, it can squeeze the gas in the air collecting chamber 12, so that the compressed gas can exert force on the sealing ball 18 in the horn hole 10, so that the sealing ball 18 moves downward, and the slide rod 19 can be retracted into the mounting tube 17, so that the sealing ball 18 no longer seals the horn hole 10.

[0035] Working principle: When the compressor body 1 is running, the two electric push rods 15 on the outer wall of the exhaust chamber 16 are started at the same time, so that the two electric push rods 15 can push the annular piston plate 14 in the sliding chamber 13 to move back and forth. When the annular piston plate 14 moves toward the exhaust chamber 16, the gas in the annular piston plate 14 is squeezed, and at the same time, the external gas can be absorbed through multiple one-way intake valves 2, and the external gas is sucked into the gas collecting chamber 12. Because the one-way ventilation pipe 6 can only allow the gas in the gas collecting chamber 12 to flow into the exhaust chamber 16, the gas in the exhaust chamber 16 can be discharged through the one-way exhaust valve 5, and at the same time, part of the gas can start the flow mechanism on the liquid storage tank 4, so that the coolant in the liquid storage tank 4 can flow in the flow pipe 7. Thereby, the gas entering into the gas collecting chamber 12 is cooled, and when the annular piston plate 14 moves toward the gas collecting chamber 12, the gas in the gas collecting chamber 12 can be squeezed, and as the annular piston plate 14 continues to move, the compressed gas can push open the one-way sealing mechanism in the trumpet hole 10, so that the gas can enter into the space between the annular sealing plate 11 and the bottom of the gas collecting chamber 12 through the trumpet hole 10, and then enter into multiple one-way ventilation pipes 6, and flow into the exhaust chamber 16 from the multiple one-way ventilation pipes 6. Such a cycle can make the cooled airflow flow continuously on the surface of the compressor body 1, and can quickly take away the heat generated by the compressor body 1 during operation, thereby greatly improving the heat dissipation effect of the compressor body 1.

When the annular piston plate 14 moves toward the exhaust chamber 16 under the action of the electric push rod 15, the air flow in the exhaust chamber 16 is squeezed and discharged through the one-way exhaust valve 5, and then enters the driving cylinder 31 through the one-way air supply pipe 32 connected to the one-way exhaust valve 5. The air flow flows in the driving cylinder 31 and can rotate the rotating shaft 37 through the driving blades 39.

[0038] As a further solution in the present invention, another part of the rotating shaft 37 inside the heat sink 30 is fixedly connected to the outer wall with multiple fan blades 35 at equal distances, and the outer wall of the heat sink 30 is provided with an air inlet 36, which is located between the fan blades 35 and the driving cylinder 31.

[0039] Working principle: when the annular piston plate 14 moves toward the exhaust chamber 16 under the action of the electric push rod 15, the airflow in the exhaust chamber 16 is squeezed and discharged through the one-way exhaust valve 5, and then enters the driving cylinder 31 through the one-way air supply pipe 32 connected to the one-way exhaust valve 5.
