Description

Technical Field

[0001] The invention relates to the field of air compressors, in particular to an air compressor with high heat dissipation performance. Background Art

[0002] A high-pressure compressor is a mechanical structure used to increase gas pressure and transport gas. It is a working machine that converts the power energy of a prime mover into gas pressure energy. There are many types of high-pressure compressors with a wide range of uses. It is known as "general machinery". Compressors are widely used in many departments of the national economy and national defense construction, especially in the petroleum, chemical, power and other industrial fields. It has become an indispensable key equipment. In chemical production, in order to ensure that certain synthesis processes can be carried out under high pressure, the gas is pressurized to the required pressure through a compressor. In addition, refrigeration and gas separation are also inseparable from compressed gas.

[0004] Although the above patent can achieve dual heat dissipation effects, when the air compressor is in operation, the temperature can be quickly cooled by the water-cooling plate. However, due to the concentrated cooling area, the cooling gas used to dissipate heat inside the air compressor directly enters the air compressor and comes into contact with high-temperature components, resulting in uneven expansion / contraction of components in different areas, local stress concentration, and possible plastic deformation or microcracks, thereby reducing the service life of the air compressor. For this reason, we provide an air compressor with high heat dissipation performance to solve the above problems. Summary of the Invention

[0007] As a further solution of the present invention: the channel switching assembly includes through holes opened on the inner sides of the three partitions, and the four heating chambers are connected through the three through holes. A second guide pipe is installed at the air outlet of one of the heating chambers, and one end of the second guide pipe passes through the outside of the heating box, and the through holes close to each other are arranged in pairs, one in front and one behind.

[0008] As a further solution of the present invention: the channel switching assembly also includes a sealing baffle arranged at each of the through-hole ports and the second guide pipe port, one side of each partition and one side of the heating box are fixedly connected to a fixed seat, the sealing baffle is rotatably connected to the inner side of the fixed seat, both sides of the sealing baffle are fixedly connected with a rotating shaft, and one end of the rotating shaft passes through the outside of the fixed seat and is rotatably connected to the fixed seat, a torsion spring is installed between the rotating shaft and the fixed seat, and a power pushing unit is provided on one side of the sealing baffle.

[0009] As a further solution of the present invention: the power pushing unit includes an electric push rod installed on one side of the heating box, the output end of the electric push rod is connected to a connecting plate, four rectangular rods are fixedly connected to the inner side of the connecting plate, one end of each of the rectangular rods is fixedly connected to a U-shaped frame, the inner side of each of the U-shaped frames is rotatably connected to a roller, and the roller is attached to the outer wall of the sealing baffle.

[0010] As a further solution of the present invention: the regulating mechanism includes an electromagnetic reversing valve fixedly connected to the other end of the first guide pipe, and one side of the electromagnetic reversing valve is fixedly connected to a reflux outlet pipe.

[0011] As a further solution of the present invention: the adjustment mechanism further includes a plurality of cooling grooves provided inside the housing, and connecting grooves are alternately provided between the two sides of every two cooling grooves.

[0012] As a further solution of the present invention: the other end of the electromagnetic reversing valve is fixedly connected to one side of the casing and communicates with the cooling groove.

[0013] As a further solution of the present invention: the cooling groove and the connecting groove are interconnected to form a continuous air duct.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the cooperation of the first solenoid valve and the second solenoid valve and other parts, gases at 70 degrees, 50 degrees, 30 degrees, and 10 degrees can be introduced into the casing in sequence for gradient cooling. Heat exchange will reduce the internal temperature of the compressor, avoid component damage and performance degradation due to high temperature, and extend the service life of the compressor. In addition, compared with directly introducing low-temperature gas, the introduction of gases with different temperature gradients in sequence can make the temperature change more gentle, reduce the thermal stress impact on the compressor caused by rapid temperature changes, and thus increase the overall service life of the compressor; 2. By arranging the cooperation of parts such as the second guide pipe, the air enters the air compressor inlet through the second guide pipe, so that the air inhaled by the air compressor can be high-temperature gas. Especially in a humid environment, when the unheated cold air initially enters the compressor that has just been running, the temperature rises during the compression process, and water vapor may condense into water droplets inside the compressor. These water droplets will corrode the components of the compressor, affecting its performance and life. Heating the intake air when the air compressor is just running can increase the dew point temperature of the air, reduce the possibility of condensation, and protect the compressor components from corrosion. 3. Through the cooperation of the electromagnetic reversing valve and other parts, the air flow passes through the continuous air duct (cooling groove + connecting groove) through various parts of the shell, avoiding the problems of insufficient air flow at the end and decreasing heat dissipation efficiency in traditional unidirectional flow. When the air inlet and exhaust direction are switched, the flow path of the air flow in the shell changes continuously, forming a turbulent effect, destroying the boundary layer of the heating surface, increasing the contact area between the air and the shell and the heat exchange efficiency. For example, when switching from air inlet on both sides to air inlet in the middle, the air flow will produce cross flow at the connecting groove, strengthening the flushing effect on the heating element, thereby further improving the overall heat dissipation effect of the device.

The channel switching assembly includes a through hole 15 opened on the inner side of the three partitions 11, and the four heating chambers are connected through the three through holes 15. A second air guide pipe 12 is installed at the air outlet of one of the heating chambers, and one end of the second air guide pipe 12 passes through the outside of the heating box 4. The through holes 15 close to each other are arranged one in front and one behind. The channel switching assembly also includes a sealing baffle 16 arranged at the end of each through hole 15 and the end of the second air guide pipe 12. One side of each partition 11 is fixedly connected to a fixing seat 17 on one side of the heating box 4. The sealing baffle 16 is rotatably connected to the inner side of the fixing seat 17. A rotating shaft 19 is fixedly connected to both sides of the sealing baffle 16, and one end of the rotating shaft 19 passes through the outside of the fixing seat 17 and is rotatably connected to the fixing seat 17. A torsion spring 20 is installed between the rotating shaft 19 and the fixing seat 17, and a power pushing unit is provided on one side of the sealing baffle 16; The regulating mechanism includes an electromagnetic reversing valve 24 fixedly connected to the other end of the first guide tube 7, and a return air outlet pipe 25 is fixedly connected to one side of the electromagnetic reversing valve 24. The regulating mechanism also includes a plurality of cooling grooves 26 provided inside the housing 3, and connecting grooves 27 are staggered between the two sides of each two cooling grooves 26. The other end of the electromagnetic reversing valve 24 is fixedly connected to one side of the housing 3 and communicates with the cooling grooves 26. The cooling grooves 26 and the connecting grooves 27 communicate with each other to form a continuous air duct. The temperatures inside the four heating chambers heated by the heating tubes 14 are 70 degrees, 50 degrees, 30 degrees, and 10 degrees from the outside to the inside, respectively. When the inside of the casing 3 needs to dissipate heat, the fan 13 is started, and the first solenoid valve 9 and the corresponding second solenoid valve 10 located on the outermost side are opened. The fan 13 rushes outside air into the U-shaped tube 6 located on the outermost side with the highest temperature, and enters the inner part of the outermost heating chamber at 70 degrees to heat it up. The heated air is introduced into the first guide pipe 7 through the second solenoid valve 10. At this time, the electromagnetic reversing valves 24 on both sides of the casing 3 are opened and the two electromagnetic reversing valves 24 in the middle are closed. The electromagnetic reversing valve 24 corresponding to the 70-degree heating chamber blows air into the casing 3, and the electromagnetic reversing valve 24 on the other side exhausts air to the outside through the reflux outlet pipe 25 (at this time, the electromagnetic reversing valve 24 of the switching channel will not ventilate the corresponding first guide pipe 7), and then the 70-degree hot air is transported to the inside of the casing 3 through the first guide pipe 7. Since the temperature inside the casing 3 is about 80 degrees when heat dissipation is required, a temperature of 70 degrees is initially introduced for heat dissipation, and the heat is discharged from the electromagnetic reversing valve 24 for exhausting air to the outside. After the heat dissipation cycle is carried out in sequence, the first electromagnetic valve 9 and the second electromagnetic valve 10 connected to the 70-degree heating chamber are closed. At the same time, the electromagnetic reversing valves 24 on both sides are set to exhaust air to the outside, and the first electromagnetic valve 9 and the second electromagnetic valve 10 connected to the 50-degree heating chamber are opened. At the same time, the electromagnetic reversing valve 24 connected to the 50-degree heating chamber is opened, and ventilation and cooling are carried out again in sequence. The cycle is carried out in sequence, so that the inside of the casing 3 can be gradiently cooled. The heat exchange will reduce the temperature inside the compressor, avoid damage to components and performance degradation due to high temperature, and extend the service life of the compressor. In addition, the introduction of gases with different temperature gradients in sequence can make the temperature change smoother than directly introducing low-temperature gas, reducing the thermal stress shock to the compressor caused by rapid temperature changes. When the inside of the shell 3 needs to dissipate heat, close the two middle electromagnetic reversing valves 24, open the electromagnetic reversing valves 24 on both sides, the air outlet directions of the electromagnetic reversing valves 24 on both sides are opposite, and the electromagnetic reversing valves 24 running in the forward direction pass the air flow inside the 70-degree heating chamber into the corresponding cooling groove 26 here, so that the air flow inside the 70-degree heating chamber passes through the entire shell 3 through the continuous air duct. In the stable operation stage of the air compressor with high heat dissipation performance, the heat emitted from the entire part is relatively uniform. At this time, change the electromagnetic reversing valves 24 on both sides to reverse operation, start one electromagnetic reversing valve 24 for forward operation, and you can The 50-degree gas is introduced into the shell 3 and discharged to the outside from the electromagnetic reversing valves 24 on both sides. After a period of time, the electromagnetic reversing valves 24 corresponding to 30 degrees are started to operate in the forward direction and discharged to the outside from the electromagnetic reversing valves 24 on both sides. After running for a period of time, the two electromagnetic reversing valves 24 in the middle are closed, and the electromagnetic reversing valves 24 corresponding to 70 degrees switch the channel to exhaust air through the reflux outlet pipe 25. At the same time, the electromagnetic reversing valves 24 corresponding to 10 degrees pass the gas into the shell 3 and circulate it once before discharging it, so that the airflow passes through the continuous air duct (cooling groove 26). + connecting slot 27) flows through various parts of the housing, avoiding the problems of insufficient end airflow and reduced heat dissipation efficiency in traditional unidirectional flow. For example, during stable operation, the electromagnetic reversing valve is operated in reverse to allow airflow to pass through the housing from different directions, covering "dead zones" that may have been formed by unidirectional flow (such as corners and the leeward side of the heating element). When the air intake and exhaust directions are switched, the flow path of the air within the housing continuously changes, forming a turbulent effect, destroying the boundary layer of the heating surface, increasing the contact area between the air and the housing and the heat exchange efficiency. For example, when switching from side air intake to center air intake, the airflow will generate cross flow at the connecting slot 27, strengthening the flushing effect on the heating element, thereby further improving the overall heat dissipation effect of the device; The second solenoid valves 10 corresponding to the four solenoid reversing valves 24 are in an open state when the corresponding solenoid reversing valves 24 allow gas to enter the housing 3, and are in a closed state when the corresponding solenoid reversing valves 24 are exhausting gas, thereby ensuring normal ventilation and circulation of the equipment; Or 30 degrees according to the temperature inside the shell 3, the air flow inside the heating chamber passes through the continuous air duct and the electromagnetic reversing valve 24 running in reverse on both sides to be discharged from the shell 3 from the return air outlet pipe 25 See also Figures 5 to 7 The power pushing unit includes an electric push rod 23 installed on one side of the heating box 4. The output end of the electric push rod 23 is connected to the connecting plate 8. Four rectangular rods 18 are fixedly connected to the inner side of the connecting plate 8. One end of each rectangular rod 18 is fixedly connected to a U-shaped frame 21. The inner side of each U-shaped frame 21 is rotatably connected to a roller 22, and the roller 22 is attached to the outer wall of the sealing baffle 16; When the casing 3 is just started and in the initial stage of operation, the first solenoid valve 9 connected to the 10-degree heating chamber is opened. At this time, the four second solenoid valves 10 are in the closed state, and the electric push rod 23 is started. The output end of the electric push rod 23 drives the connecting plate 8 to move away from the heating box 4, thereby driving a roller 22 to move away from the sealing baffle 16 through a rectangular rod 18. When the roller 22 is separated from the sealing baffle 16, the torsion spring 20 is no longer subjected to external force to drive the rotating shaft 19 to drive the sealing baffle 16 to reset, so that the through hole 15 is no longer blocked. When the air enters the 10-degree heating chamber and heats up, it can enter through the through hole 15. The air enters the heating chamber at 30, 50 and 70 degrees Celsius, and finally enters the air inlet of the air compressor through the second guide pipe 12, so that the air inhaled by the air compressor can be high-temperature gas. Especially in a humid environment, when the unheated cold air initially enters the compressor that has just been run, the temperature rises during the compression process, and water vapor may condense into water droplets inside the compressor. These water droplets will corrode the components of the compressor and affect its performance and life. Heating the intake air of the air compressor when it is just running can increase the dew point temperature of the air, reduce the possibility of condensation, and protect the compressor components from corrosion. When the air compressor is initially operated, the incoming air is heated. After a period of operation, the air heating operation is stopped when the temperature inside the air compressor reaches a certain level, and the heating device is used to dissipate heat from the air compressor.
