Description

Technical Field

[0001] This utility model relates to the field of exchanger head technology, specifically an exchanger head with a gas diversion structure. Background Technology

[0002] Plate-fin heat exchangers are widely used in many fields such as air separation equipment, petrochemicals, transportation equipment, and aerospace due to their compact structure, lightweight design, high heat transfer efficiency, and strong adaptability. In air separation equipment, plate-fin heat exchangers are key equipment for heat exchange in condensation, liquefaction, and evaporation. Their heat exchange efficiency directly determines the energy consumption in the air separation process, thus having a significant impact on economic benefits. Therefore, we propose a welded end cap for plate-fin heat exchangers.

[0003] An existing patent (publication number: CN217716094U) discloses a welded end cap for a plate-fin heat exchanger, relating to the technical field of plate-fin heat exchangers. It includes a shell, a main pipe welded to the top surface of the shell, and a sieve plate installed below the interior of the main pipe. Second baffles are welded to both sides of the bottom of the sieve plate, and a second spring is connected to the outer side of the second baffle. A first baffle is connected to the end of the second spring, and a hinge is installed between the first baffle and the sieve plate. In this invention, when the first baffle rotates to be perpendicular to the sieve plate, it can send the first baffle and the sieve plate into the interior of the main pipe. After the first baffle and the sieve plate are sent into the main pipe, the sieve plate continues to move downwards, causing the first baffle and the second baffle to enter the interior of the shell. At this time, the first baffle can unfold under the elastic force of the second spring, thereby cooperating with the second baffle to divert the gas entering the interior of the shell from the main pipe, resulting in uniform inlet flow and high heat exchange efficiency. Existing heat exchanger heads rely on two sets of baffles to divide the airflow, which can only roughly divide the airflow into four groups, resulting in limited flow division effect. Utility Model Content

[0004] The purpose of this invention is to provide an exchanger head with a gas diversion structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an exchanger head with a gas diversion structure, including an inlet pipe, the inner wall of which is integrally formed with three sets of spiral guide vanes, a central tube fixedly connected between the three sets of spiral guide vanes, a diversion shell connected to the bottom end of the central tube, a rotating diversion assembly provided in the middle of the inner side of the diversion shell, and a plurality of secondary diversion heads fixedly connected to the bottom surface of the diversion shell, and a quick docking assembly provided on the outer side of the secondary diversion heads;

[0006] The rotary diversion assembly includes a support cylinder fixedly connected to the middle of the bottom surface inside the diversion shell. A support frame is fixedly connected to the top of the support cylinder. A fixed ball is integrally formed at the top of the support frame. A spherical sleeve is movably fitted on the outside of the fixed ball. A support rod is integrally formed on the outside of the spherical sleeve. A conical diversion plate is fixedly connected to the top of the support rod. A flow port is opened in the middle of the conical diversion plate. Several wind baffles are fixedly connected to the top surface of the conical diversion plate. Several sets of ventilation holes are opened in the middle of the conical diversion plate.

[0007] Preferably, some of the wind baffles are spiral-shaped, and the direction of rotation of the wind baffles is opposite to that of the spiral guide vanes.

[0008] Preferably, the secondary diverter head consists of a funnel shell, a diverter head body, and a flow guiding channel. The top of the diverter head body is conical, and the top edge of the funnel shell is higher than the highest point of the top of the diverter head body.

[0009] Preferably, the flow guiding channel consists of a flow splitting channel and a capillary channel.

[0010] Preferably, the quick docking assembly includes a fixed tube, the fixed tube having an oil storage chamber, and a trigger rod slidably connected inside the oil storage chamber.

[0011] Preferably, the outer side of the fixed tube is integrally formed with an oil storage cavity two, and a push rod is movably connected inside the oil storage cavity two. One end of the push rod extends to the outer side of the oil storage cavity two and is connected to the extrusion ring. The oil storage cavity two and the oil storage cavity one are connected by a flow tube.

[0012] Preferably, the side of the extrusion ring away from the push rod is designed with an inclined surface, and the inclined surface of the extrusion ring is in contact with the triangular fixing ring. The triangular fixing ring is slidably connected to the middle of the arc-shaped groove. The arc-shaped groove is opened on the wall of the fixed tube, and the bottom surface of the arc-shaped groove is provided with a small protrusion.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this invention, gas enters through the inlet pipe, and the spiral guide vanes and central tube divert the gas. The gas guided by the spiral guide vanes enters the diversion shell in a spiral shape, thereby driving the rotating diversion assembly to rotate and quickly distribute the gas to the edge of the diversion shell. At the same time, the gas entering through the central tube maintains a straight descent, and this part of the gas directly enters the middle of the diversion shell through the flow port. This structure makes the gas distribution uniform throughout the diversion shell. Subsequently, the gas continues to pass through the secondary diversion head, where it is diverted again and finally flows out from the capillary channel. The secondary diversion is mainly achieved through the guide channel opened on the cylindrical surface of the diversion head body, making the structure more compact and improving the diversion effect. This makes the gas distribution more uniform when entering the exchanger, and the heat exchange effect is also improved. The quick docking assembly also allows the exchanger head to dock with external pipes more quickly, improving docking efficiency. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 8 This utility model provides a technical solution: an exchanger head with a gas diversion structure, including an inlet pipe 1, the inner wall of the inlet pipe 1 is integrally formed with three sets of spiral guide vanes 2, a central pipe 3 is fixedly connected between the three sets of spiral guide vanes 2, the bottom end of the central pipe 3 is connected to a diversion shell 4, a rotating diversion component 5 is provided in the middle of the inner side of the diversion shell 4, and a number of secondary diversion heads 6 are fixedly connected to the bottom surface of the diversion shell 4, and a quick docking component 7 is provided on the outer side of the secondary diversion head 6.

[0026] In this embodiment, as Figure 2 , Figure 3 and Figure 5As shown, the rotary diversion assembly 5 includes a support cylinder 501 fixedly connected to the middle of the bottom surface inside the diversion shell 4. A support frame 502 is fixedly connected to the top of the support cylinder 501. A fixed ball 503 is integrally formed at the top of the support frame 502. A spherical sleeve 504 is movably sleeved on the outside of the fixed ball 503. A support rod 505 is integrally formed on the outside of the spherical sleeve 504. A conical diversion plate 506 is fixedly connected to the top of the support rod 505. A flow port 507 is opened in the middle of the conical diversion plate 506. Several wind baffles 508 are fixedly connected to the top surface of the conical diversion plate 506. Several sets of ventilation holes 509 are opened in the middle of the conical diversion plate 506. The blade 508 is spiral-shaped, and the direction of rotation of the baffle 508 is opposite to that of the spiral guide blade 2. When the airflow passes through the guide blade 2, it spirals out of the intake pipe 1 and hits the top surface of the conical splitter blade 506. At this time, the airflow will push the conical splitter blade 506 to rotate through the baffle 508, throwing the airflow to all sides, thereby quickly dispersing the gas that has entered the splitter shell 4 to the surrounding area of ​​the splitter shell 4. The spherical sleeve 504 and the fixed ball 503 cooperate to make the conical splitter blade 506 rotate, and the top of the support frame 502 contacts the bottom edge of the spherical sleeve 504 to prevent the main splitter blade 506 from tilting and to ensure that the conical splitter blade 506 is horizontal.

[0027] In this embodiment, as Figure 6 and Figure 8 As shown, the secondary diverter head 6 consists of a funnel shell 601, a diverter head body 602, and a guide channel 603. The top of the diverter head body 602 is conical, and the top edge of the funnel shell 601 is higher than the highest point of the top of the diverter head body 602. The guide channel 603 consists of a diverter channel 603a and a capillary channel 603b. Through the cooperation of the funnel shell 601 and the conical top of the diverter head body 602, the gas can be guided to the diverter channel 603a. After entering the diverter channel 603a, the gas will be diverted again and enter the capillary channel 603b, realizing secondary diversion. The secondary diversion is mainly achieved through the guide channel 603 opened on the cylindrical surface of the diverter head body 602. The structure is more compact, the diversion effect is improved, and the gas is more evenly distributed when entering the exchanger, thus improving the heat exchange effect.

[0028] In this embodiment, as Figure 6 and Figure 7As shown, the quick-connect assembly 7 includes a fixed tube 701, with an oil storage chamber 702 inside the fixed tube 701. A trigger rod 703 is slidably connected inside the oil storage chamber 702. An oil storage chamber 704 is integrally formed on the outer side of the fixed tube 701. A push rod 705 is movably connected inside the oil storage chamber 704. One end of the push rod 705 extends to the outer side of the oil storage chamber 704 and connects to a compression ring 706. The oil storage chamber 704 and the oil storage chamber 702 are connected by a flow pipe 707. The side of the compression ring 706 away from the push rod 705 is designed with a slope, and the slope of the compression ring 706 fits against a triangular fixing ring 709. The triangular fixing ring 709 is slidably connected to the middle of an arc-shaped groove 708. The arc-shaped groove 708 is formed on the wall of the fixed tube 701, and the bottom surface of the arc-shaped groove 708 has small protrusions. When docking pipes are required, the outer pipe is pushed into the fixed tube 701, and the trigger rod is activated. When rod 703 is pushed upward, piston plates are provided at the top of both trigger rod 703 and push rod 705. When trigger rod 703 moves upward, the piston plate at its top will squeeze the hydraulic oil in oil reservoir 1 702 through flow pipe 707 into oil reservoir 2 704. At this time, push rod 705 in oil reservoir 2 704 will be pushed downward. The downward movement of push rod 705 will push compression ring 706 downward. The downward movement of compression ring 706 will squeeze triangular fixing ring 709 into the fixing pipe 701. Because the two sides of arc groove 708 that fit with triangular fixing ring 709 are also inclined, and the inclination angle is consistent with the inclination angle of the inclined surface of triangular fixing ring 709, when triangular fixing ring 709 is squeezed, it will only move into the fixing pipe 701, thereby locking the external pipe connected to the fixing pipe 701. Compared with the traditional bolt tightening method, it is faster and has higher fixing efficiency.

[0029] The usage and advantages of this utility model: The working process of this exchanger head with a gas diversion structure is as follows:

[0030] First, gas enters through the inlet pipe 1. The spiral guide vane 2 and the central pipe 3 divide the gas. The gas guided by the spiral guide vane 2 enters the distribution shell 4 in a spiral shape, thereby driving the rotating distribution assembly 5 to rotate and quickly distribute the gas to the edge of the distribution shell 4. At the same time, the gas entering through the central pipe 3 continues to descend in a straight line. This part of the gas directly enters the middle of the distribution shell 4 through the flow port 507. This structure makes the gas distribution uniform throughout the distribution shell 4. Subsequently, the gas continues to pass through the secondary distribution head 6. In the secondary distribution head 6, the gas is divided again and finally flows out from the capillary channel 603b. The secondary division is mainly achieved by the guide channel 603 opened on the cylindrical surface of the distribution head body 602. The structure is more compact and the division effect is improved, making the gas distribution more uniform when entering the exchanger and improving the heat exchange effect. The quick docking assembly 7 also enables the exchanger head to dock with external pipes more quickly, improving docking efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
