Description

Technical Field

[0001] This invention relates to the field of cooling equipment technology, and in particular to a high-efficiency cooler. Background Technology

[0002] A cooler is a heat exchange device used to cool fluids, typically using water or air as the coolant to remove heat. It is a widely used heat exchange device in industries such as metallurgy, chemical engineering, energy, transportation, light industry, and food processing. It is extensively used as a cooling and protection auxiliary device for large electrical equipment such as high-power silicon rectifiers, induction furnaces, and medium-frequency furnaces, employing pure water, water-air, oil-water, and oil-air cooling systems. It can be mainly classified into shell-and-tube coolers, plate coolers, and air-cooled coolers.

[0003] Existing shell-and-tube coolers primarily rely on thin cooling tubes inside the unit to cool oil and water. These tubes are directly installed in the cavity inside the cooler tubes, and the coolant flows directly through this cavity during operation. Because this cavity is relatively large, the flow rate of the coolant is limited, preventing the coolant and the heat it carries from being dissipated quickly, thus reducing cooling efficiency. Furthermore, the oil and water to be cooled inevitably contain some debris. To prevent this debris from entering the cooler and causing blockages, filters are often installed on the external oil inlet pipe. However, these filters are prone to clogging, affecting the flow rate. This necessitates frequent removal, cleaning, or replacement of the filters, which not only affects the normal operation of the cooler but also presents significant operational inconvenience. Summary of the Invention

[0004] In view of this, the present invention provides a high-efficiency cooler to solve the problems of the current shell-and-tube cooler having insufficient cooling efficiency, filter element affecting cooler operation during cleaning, and inconvenient operation.

[0005] This invention provides a high-efficiency cooler, specifically comprising: a main body; an oil inlet pipe fixedly connected to the left side of the main body; an oil outlet pipe fixedly connected to the right side of the main body; a water inlet pipe fixedly connected to the bottom right side of the main body; a water outlet pipe fixedly connected to the top left side of the main body; an air inlet pipe embedded in the bottom right side of the main body, with its right end connected to the cold air outlet of an external vortex pipe; an air outlet pipe embedded in the bottom left side of the main body; two inner partitions fixedly and symmetrically arranged inside the main body; a plurality of cooling pipes fixedly connected between the two inner partitions; and a water guide pipe provided on the outer side of each cooling pipe. Both ends of the cooling pipe are fixedly connected to the inner wall of the main body by a circular plate; each cooling pipe has a fixed air guide pipe inside, and each end of these air guide pipes is fixedly connected to an air guide plate; the left end of the air inlet pipe and the right end of the air outlet pipe are respectively connected to two air guide plates; a turbine is rotatably installed on the left side inside the oil inlet pipe; a reducer is fixedly installed on the inner bottom of the oil inlet pipe, and the right end of the turbine is connected to the reducer for transmission; a first gear is connected to the right side of the reducer through a rotating shaft; a filter cylinder is rotatably installed on the right side inside the oil inlet pipe; a second gear is fixedly connected to the left side of the filter cylinder; four circular filter plates are fixedly installed on the inner side of the filter cylinder.

[0006] Furthermore, an opening that extends through both the inside and outside is provided on the lower right side of the oil inlet pipe, and when one of the cylindrical holes inside the filter cylinder is rotated downwards, this cylindrical hole will be located to the left of the lower right opening of the oil inlet pipe.

[0007] Furthermore, the left end of the vent pipe is located to the right of the center of the opening below the right side of the oil inlet pipe, and the distance between the left end face of the vent pipe and the right side of the lower part of the oil inlet pipe is 2cm.

[0008] Furthermore, the openings at both ends of the water guide pipe are funnel-shaped structures, and the distance between the inner wall of the main water guide pipe in the middle and the outer wall of the cooling pipe is 5mm.

[0009] Furthermore, a notch is provided at the bottom of the oil inlet pipe. The top of the notch is not connected to the inside of the oil inlet pipe. A circular hole is provided on the right side of the notch, which corresponds to the left and right sides of the lower right opening of the oil inlet pipe. The inner diameter of the circular hole is equal to the inner diameter of the cylindrical hole inside the filter cartridge.

[0010] Furthermore, a notch is provided at the bottom of the oil inlet pipe. The top of the notch is not connected to the inside of the oil inlet pipe. A circular hole is provided on the right side of the notch, which corresponds to the left and right sides of the lower right opening of the oil inlet pipe. The inner diameter of the circular hole is equal to the inner diameter of the cylindrical hole inside the filter cartridge.

[0011] Further, the first gear is engaged with the second gear. An irregular plate that closely adheres to the left side of the filter cartridge is further provided inside the oil inlet pipe. When the cylindrical hole inside the filter cartridge rotates to the topmost position, the oil to be cooled on the left side of the oil inlet pipe can flow into the cavity on the right side of the oil inlet pipe through this cylindrical hole.

[0012] Further, a total of four cylindrical holes penetrating from left to right are arranged in a circular pattern inside the filter cartridge, and four filter plates are respectively arranged in these four cylindrical holes. Beneficial effects

[0013] 1. The distance between the inner wall of the water guide pipe and the outer wall of the cooling pipe in the present invention is relatively small, and the coolant will not enter the cavity where the water guide pipe is located. Therefore, the space where the coolant can flow is greatly reduced, so the flow rate of the coolant will increase, enabling the coolant carrying heat to flow out quickly. Moreover, after cold air is introduced into the air guide pipe, it can further cool the oil and water inside the cooling pipe, thereby improving the cooling efficiency.

[0014] 2. The filter cartridge in the present invention is installed in the oil inlet pipe, and the filter cartridge relies on the filter plates inside it to filter the debris in the oil and water. During use, the flowing oil and water can drive the filter cartridge to rotate, and then the filter cartridge can rely on the four filter plates on its inner side to filter the debris in the oil and water in turn. At the same time, when the cold air used for cooling is discharged outward, it will also clean the debris on the four filter plates in turn, realizing automatic cleaning of the debris. There is no need to stop the normal operation of the cooler during cleaning, making it more convenient to use. Brief description of the drawings

[0027] To make the objectives, solutions, and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present invention.

[0028] Example: Please refer to Figures 1 to 8 As shown:

[0029] This invention provides a high-efficiency cooler, comprising a main body 1; an oil inlet pipe 2 is fixedly connected to the left side of the main body 1, which supports the internal cooling structure, and the oil inlet pipe 2 is used to introduce oil to be cooled into the main body 1; an oil outlet pipe 3 is fixedly connected to the right side of the main body 1, which discharges the cooled oil from the inside of the main body 1 to the outside; a water inlet pipe 4 is fixedly connected to the bottom right side of the main body 1, which introduces coolant into the main body 1; and a water outlet pipe 5 is fixedly connected to the top left side of the main body 1, which discharges the coolant that has absorbed heat from the inside of the main body 1 to the outside. An air inlet pipe 6 is embedded in the bottom right side of the main body 1, and the right end of the air inlet pipe 6 is connected to the cold air outlet of the external vortex pipe. When in use, external air is introduced into the vortex pipe by a compression pump, and then the cold air discharged from the vortex pipe will enter the air guide plate 7 located on the right side through the air inlet pipe 6, so that the cold air enters the air guide pipe 12 to cool the oil and water in the cooling pipe 10. An air outlet pipe 8 is embedded in the bottom left side of the main body 1. The air outlet pipe 8 is used to discharge the cold air after absorbing heat to the outside, and the air discharged through the air outlet pipe 8 can also blow directly onto the filter plate 18, so as to clean the debris filtered on the filter plate 18. Two inner baffles 9 are symmetrically fixed inside the main body 1. These baffles support the cooling pipes 10 and separate the oil / water from the coolant. Several cooling pipes 10 are fixedly connected between the two inner baffles 9. These cooling pipes 10 guide the oil / water from the left side of the main body 1 into the cavity on the right side of the main body 1, and also cool the oil / water during this process. Several semi-circular annular plates are staggered inside each cooling pipe 10, and the inner sides of these semi-circular annular plates are fixedly connected to the outer wall of the air guide pipe 12. Therefore, the oil / water continuously ripples and tumbles as it flows through the cooling pipes 10, facilitating more even heat transfer. A water guide pipe 11 is provided on the outer side of the cooling pipe 10, and the two ends of these water guide pipes 11 are fixedly connected to the inner wall of the main pipe 1 by a circular plate. The water guide pipe 11 is used to guide the coolant from right to left. Because the coolant will come into contact with the outer wall of the cooling pipe 10 when it flows, it can cool the oil and water in the cooling pipe 10. Moreover, because the distance between the inner wall of the water guide pipe 11 and the outer wall of the cooling pipe 10 is small, and the coolant will not enter the cavity outside the water guide pipe 11, the space for the coolant to flow is greatly reduced, so the flow rate of the coolant will increase, thereby allowing the coolant carrying heat to flow out quickly, thereby improving the cooling efficiency.Each cooling pipe 10 has a fixed air guide pipe 12 inside, and each end of these air guide pipes 12 is fixedly connected to an air deflector 7. The air guide pipe 12 is used to guide the cold air from the right side to the left side, and the cold air flow will also absorb the heat of the oil and water in the cooling pipe 10, thereby further improving the cooling efficiency. The air deflector 7 can evenly guide the cold air from the intake pipe 6 into the air guide pipe 12 and discharge the cold air in the air guide pipe 12 into the exhaust pipe 8. The left end of the intake pipe 6 and the right end of the exhaust pipe 8 are respectively connected to two air deflectors 7, and the air deflectors 7 can guide the cold air from the intake pipe 6 into the exhaust pipe 8. The air is evenly introduced into the air guide pipe 12 and the cold air in the air guide pipe 12 is discharged into the air outlet pipe 8; a turbine 13 is rotatably installed on the left side inside the oil inlet pipe 2. When the oil pump that pushes oil and water externally delivers oil and water to the oil inlet pipe 2, it can drive the turbine 13 to rotate. Then the turbine 13 will transmit the rotational power to the reducer 14. The reducer 14 then drives the filter cylinder 16 to rotate slowly through gear engagement, thereby causing the position of the filter plate 18 in the filter cylinder 16 to change continuously; a reducer 14 is fixedly installed on the inner side of the bottom of the oil inlet pipe 2, and the right end of the turbine 13 is connected to the reducer 14 for transmission. The reducer 14 can reduce the power of the turbine 13 and drive the first gear 15 to rotate; the right side of the reducer 14 is connected to the first gear 15 via a rotating shaft. When the first gear 15 rotates, it can cooperate with the second gear 17 to drive the filter cylinder 16 to rotate slowly, so that the four filter plates 18 inside the filter cylinder 16 can rotate to the top in turn to filter debris in the oil and water; a filter cylinder 16 is rotatably installed on the right side inside the oil inlet pipe 2. The filter cylinder 16 is used to guide the oil and water in the oil inlet pipe 2; the filter cylinder 16 has four cylindrical holes arranged in a ring inside, and the four The filter plates 18 are respectively disposed in the four cylindrical holes, so when the filter cylinder 16 rotates, the four filter plates 18 on its inner side can rotate to the top in turn to filter debris in the oil and water. A second gear 17 is fixedly connected to the left side of the filter cylinder 16. When the first gear 15 rotates, it can cooperate with the second gear 17 to drive the filter cylinder 16 to rotate slowly, thereby enabling the four filter plates 18 on the inner side of the filter cylinder 16 to rotate to the top in turn to filter debris in the oil and water. Four circular filter plates 18 are fixedly disposed inside the filter cylinder 16, and the filter plates 18 are used to filter debris in the oil and water.

[0030] The oil inlet pipe 2 has an opening that runs through both the inside and outside. When one of the cylindrical holes inside the filter cylinder 16 is rotated downwards, this cylindrical hole will be located to the left of the opening on the lower right side of the oil inlet pipe 2. When the cylindrical hole inside the filter cylinder 16 is rotated downwards, the filter plate 18 inside it will also be located to the left of this opening. At this time, the air discharged outwards through the air outlet pipe 8 will blow directly onto the filter plate 18, thus cleaning the debris filtered on the filter plate 18.

[0031] The left end of the air outlet pipe 8 is located to the right of the center of the lower right opening of the oil inlet pipe 2, and the distance between the left end face of the air outlet pipe 8 and the right side of the lower part of the oil inlet pipe 2 is 2cm. When the cylindrical hole inside the filter cylinder 16 is rotated to the lower position, the filter plate 18 inside it will also be located to the left of this opening. At this time, the air discharged outward through the air outlet pipe 8 will blow directly onto the filter plate 18, thus cleaning the debris filtered on the filter plate 18. Moreover, because the air outlet pipe 8 is close to the lower right opening of the oil inlet pipe 2, it can ensure that the air discharged through the air outlet pipe 8 can be blown into this opening.

[0032] The water guide pipe 11 has funnel-shaped openings at both ends, and the distance between the inner wall of the main section of the water guide pipe 11 and the outer wall of the cooling pipe 10 is 5mm. The water guide pipe 11 is used to guide the coolant from right to left. The funnel-shaped openings at both ends make it easier for the coolant to enter its interior. Because the coolant will come into contact with the outer wall of the cooling pipe 10 when it flows, it can cool the oil and water in the cooling pipe 10. Moreover, because the distance between the inner wall of the water guide pipe 11 and the outer wall of the cooling pipe 10 is small, and the coolant will not enter the cavity outside the water guide pipe 11, the space for the coolant to flow is greatly reduced. This increases the flow rate of the coolant, allowing the coolant carrying heat to flow out quickly, thereby improving the cooling efficiency.

[0033] The oil inlet pipe 2 has a notch at its bottom. The top of the notch is not connected to the inside of the oil inlet pipe 2. On the right side of the notch, there is a circular hole that corresponds to the lower right opening of the oil inlet pipe 2. The inner diameter of the circular hole is equal to the inner diameter of the cylindrical hole inside the filter cylinder 16. This ensures that the cylindrical hole inside the filter cylinder 16 can only guide and filter oil and water when it is rotated to the top, preventing oil and water from leaking out. Moreover, the debris blown down by the air discharged through the air outlet pipe 8 can fall down through the notch at the bottom of the oil inlet pipe 2. During use, the filter cylinder 16 is rotated by the flowing oil and water. The filter cylinder 16 can then filter the debris in the oil and water in turn using the four filter plates 18 on its inner side. At the same time, when the cooling air is discharged outward, it will also clean the debris on the four filter plates 18 in turn. The cleaning of debris is automated and does not require stopping the normal operation of the cooler, making it more convenient to use.

[0034] The first gear 15 and the second gear 17 are engaged. Inside the oil inlet pipe 2, there is a special-shaped plate that is in close contact with the left side of the filter cylinder 16. When the cylindrical hole inside the filter cylinder 16 rotates to the top, the oil to be cooled on the left side of the oil inlet pipe 2 can flow into the cavity on the right side of the oil inlet pipe 2 through this cylindrical hole. When the first gear 15 rotates, it can cooperate with the second gear 17 to drive the filter cylinder 16 to rotate slowly, so that the four filter plates 18 inside the filter cylinder 16 can rotate to the top in turn to filter debris in the oil and water.

[0035] The specific usage and function of this embodiment: In this invention, when the device cools oil and water, the oil and water to be cooled enter the cavity on the left side of the main body 1 through the oil inlet pipe 2, and then flow into the cavity on the right side of the main body 1 after being cooled by the cooling pipe 10, and are discharged outward through the oil outlet pipe 3. The coolant enters the right side of the main body 1 through the water inlet pipe 4, and then flows into the left side of the main body 1 through the water guide pipe 11 and is discharged outward through the water outlet pipe 5. When the coolant flows, it will come into contact with the outer wall of the cooling pipe 10, so it can cool the oil and water in the cooling pipe 10. Moreover, because the water guide pipe 1... The distance between the inner wall of the cooling pipe 10 and the outer wall of the cooling pipe 10 is small, and coolant will not enter the cavity outside the water guide pipe 11. Therefore, the space for coolant to flow is greatly reduced, which increases the flow rate of the coolant. This allows the coolant carrying heat to flow out quickly, thereby improving cooling efficiency. The cold air discharged from the vortex tube will enter the air guide plate 7 on the right side through the air intake pipe 6. Then, the cold air will enter the air guide pipe 12 and flow to the left. During the flow of the cold air, it will also absorb the heat of the oil and water in the cooling pipe 10, thus further improving the cooling efficiency. Finally, the cold air after absorbing heat... The oil is discharged through the vent pipe 8. The external oil pump, which pushes the oil and water into the inlet pipe 2, drives the turbine 13 to rotate. The turbine 13 then transmits the rotational power to the reducer 14. The reducer 14, through the engagement of the first gear 15 and the second gear 17, drives the filter cylinder 16 to rotate slowly. As the filter cylinder 16 rotates, its four inner filter plates 18 rotate to the top in turn to filter debris from the oil and water. Simultaneously, these four filter plates 18 rotate to the bottom in turn, and the air discharged through the vent pipe 8 directly blows onto the bottom of the filter cylinder. The filter plate 18 at the bottom can be used to clean the debris filtered on it. The debris blown off by the air outlet pipe 8 can fall down through the notch at the bottom of the oil inlet pipe 2. During use, the filter cylinder 16 can be rotated by the flowing oil and water. Then the filter cylinder 16 can filter the debris in the oil and water in turn by the four filter plates 18 on its inner side. At the same time, when the cooling air is discharged outward, it will also clean the debris on the four filter plates 18 in turn. The debris cleaning is automated and there is no need to stop the normal operation of the cooler during cleaning, making it more convenient to use.
