Abstract

This invention discloses a high-efficiency heat exchanger, relating to the field of heat exchanger technology. It includes a main body and multiple straight pipes extending through both ends of the main body. Each pipe has a port at one end of the main body, functionally divided into a cooling object inlet and a cooling object outlet. End faces are fixedly disposed at both ends of the main body, sharing the same cross-section as the straight pipe ports. Baffles are disposed on the end faces. This high-efficiency heat exchanger detects the cooling object through a control center. For slowly flowing cooling objects, cooling is achieved through a first heat exchange channel, reducing the cooling time. For rapidly flowing cooling objects, they enter a second heat exchange channel, where they flow back and forth within the heat exchanger in an "S" shape. This extends the transit time without increasing the overall length, increases the heat dissipation contact area, and improves the flow velocity, thereby enhancing heat exchange efficiency and achieving rapid cooling.

Description

Technical Field

[0001] This invention relates to the field of heat exchanger technology, and more specifically to a high-efficiency heat exchanger. Background Technology

[0002] As market and customer demands for engine power increase, engine power and torque have increased significantly compared to the past. At the same time, the engine's thermal load also increases, and the performance of the engine cooling system needs to be improved accordingly to ensure that the engine operates at a suitable temperature and does not overheat. However, there are usually two measures to improve the performance of the cooling system: (1) increase the size of the heat exchanger; (2) increase the flow rate of the cooling medium. Measure (1) often increases the volume of the heat exchanger, which is not conducive to the engine's external dimensions; Measure (2) often increases costs. Summary of the Invention

[0003] The purpose of this invention is to provide a high-efficiency heat exchanger to solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency heat exchanger, comprising a body and a plurality of straight pipes disposed through both ends of the body, including a port disposed at the end of the body, and the port being divided into a cooling object inlet and a cooling object outlet according to its function;

[0005] The end faces are fixedly installed at both ends of the main body and have the same cross-section as the straight pipe port;

[0006] The baffles installed on the end face form a conveying space that is connected to the inlet and outlet of the object being cooled between adjacent sides, and the back sides of the baffles form a connecting space for connecting straight pipes.

[0007] The active pivot for driving the partition to rotate includes an elastic element disposed between the partition and the body;

[0008] The partition has two workstations during its travel:

[0009] At the first station, the elastic element unfolds, and the conveying spaces at both ends correspond to form the first heat exchange channel for the object to be cooled to pass through quickly.

[0010] In the second station, the elastic element twists, and the conveying spaces at both ends are staggered, forming a second heat exchange channel in which the object to be cooled flows in an S-shape.

[0011] Preferably, the active central hub includes a beam shroud;

[0012] The beam shroud is equipped with a spiral plate, and the beam shroud abuts against the elastic element when the object being cooled is in an overspeed state.

[0013] Preferably, a locking ball is movably disposed inside the beam shroud;

[0014] The port is provided with a drive ring that engages with a locking ball, and the drive ring is provided with an external thread that engages with the thread of the partition plate.

[0015] In the locked ball engagement state, the external thread is in the opposite direction to the rotation of the beam shroud.

[0016] Preferably, the external thread is provided with a rotating tail fin.

[0017] Preferably, the beam shroud includes a narrow opening for focusing and cooling the object and a channel opened on the beam shroud, wherein a piston is disposed in the narrow opening;

[0018] The piston is subjected to pressure that changes direction, causing the object to be cooled to either flow out of the narrow port or enter the port through a channel.

[0019] Preferably, the drive ring is provided with a baffle plate for blocking the channel.

[0020] Preferably, a rubber scraper is also provided at the first end of the partition, and an abutment portion thereon is provided that is in close contact with the end face.

[0021] Preferably, the partition is provided with a locking device for engaging the end face, and the rubber scraper is provided with a water collection plate that abuts against the locking device;

[0022] The contact part is fixedly provided with a baffle part that connects with the water collection plate.

[0024] Preferably, the second end of the partition opposite to the rubber scraper is provided with a suction port pointing towards the narrow opening.

[0025] In the above technical solution, the present invention provides a high-efficiency heat exchanger with the following beneficial effects: By detecting the object to be cooled through a control center, slow-flowing objects are cooled through a first heat exchange channel, reducing the cooling time. Fast-flowing objects enter a second heat exchange channel, where they flow back and forth within the heat exchanger in an "S" shape. Without increasing the length, this extends the transit time, increases the heat dissipation contact area, and improves the flow velocity, thereby enhancing heat exchange efficiency and achieving rapid cooling.

[0039] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] like Figure 1-10 As shown, a high-efficiency heat exchanger includes a body 1 and a plurality of straight pipes 14 that pass through both ends of the body 1. The pipes include ports located at the ends of the body 1, and the ports are divided into cooling object inlet 2 and cooling object outlet 3 according to their functions.

[0041] End faces 15 are fixedly installed at both ends of the main body 1 and have the same cross-section as the port of the straight pipe 14;

[0042] The partition 7 installed on the end face 15 forms a conveying space that is connected to the cooling object inlet 2 and the cooling object outlet 3 between adjacent surfaces, and the partition 7 is a connecting space between the back sides for connecting the straight pipe 14.

[0043] The active pivot for driving the partition 7 to rotate includes an elastic member 72 disposed between the partition 7 and the body 1;

[0044] There are two workstations in the movement of partition 7:

[0045] At the first station, the elastic element 72 unfolds, and the conveying spaces at both ends correspond to form a first heat exchange channel for the object to be cooled to pass through quickly.

[0046] In the second station, the elastic element 72 is twisted, and the conveying spaces at both ends are staggered, forming a second heat exchange channel in which the object to be cooled flows in an S-shape.

[0047] Specifically, end face 15 is divided into three equal parts: A, B, and C. Figure 10As shown, A1, B1, and C1 face the cooling object inlet 2, while A2, B2, and C2 face the cooling object outlet 3. The cooling object inlets and outlets are arranged opposite each other, meaning that the ports at both ends of the main body 1 are not designated as inlets or outlets. It also includes a cooling medium inlet 4 and a cooling medium outlet 5 for conveying the cooling medium, which are used to cool and dissipate heat from the straight pipe 14.

[0048] Furthermore, the partition 7 divides the end face 15 into a conveying space and a connecting space, so as to... Figure 2 As shown for reference, the first station is the initial position of the partition 7. At this time, A1 is the conveying space at the inlet 2 of the cooling object, and A2 is the conveying space at the outlet 3 of the cooling object. A1 and A2 are connected by a straight pipe 14 to form the first heat exchange channel, so that the cooling object is conveyed from A1 to A2 through the straight pipe 14. The cooling object under the first heat exchange channel flows faster in the straight pipe 14 and has a shorter contact time with the cooling medium, which is suitable for slow-flowing cooling objects and reduces the cooling time.

[0049] When partition 7 reaches the second station, A1 remains the conveying space at the inlet 2 of the cooling object, with B1 and C1 connected. B2 or C2 becomes the conveying space at the outlet 3 of the cooling object, corresponding to A2 being connected to C2 or B2. When B2 is the conveying space, the cooling object flows from A1 to A2, then from A2 to C2, from C2 to C1, then through the connecting space into B1, and finally from B1 into B2, making the path S-shaped. The same principle applies when C2 is the conveying space. This is the second heat exchange channel, which will not be elaborated further. By achieving multiple round trips of the cooling object without lengthening the main body 1, a sufficient heat dissipation effect is achieved.

[0050] When the flow rate of the object being cooled in the first heat exchange channel is too fast, in order to improve the heat exchange efficiency, the control center drives the partition 7 to rotate 120°, thereby switching from the first heat exchange channel to the second heat exchange channel. During the rotation, since the two ends of the elastic element 72 are fixedly connected to the body 1 and the partition 7 respectively, the partition 7 rotates and drives one section of the elastic element 72 to twist.

[0051] The control center in the above technology can be equipped with a flow rate detection unit at the inlet 2 of the cooling object to detect the flow rate of the cooling object. When the flow rate exceeds the standard, the partition 7 is rotated to a specified angle by driving a motor or turbine structure. Alternatively, a temperature measuring unit can be installed at the outlet 3 of the cooling object. When the temperature drop is too low, the partition 7 is rotated by driving a motor or turbine structure. Other methods known to those skilled in the art are also acceptable.

[0052] In the aforementioned technology, the cooling target is detected by a control center. For slow-flowing targets, cooling is achieved through the first heat exchange channel, reducing the cooling time. For fast-flowing targets, the target enters the second heat exchange channel, where it flows back and forth within the heat exchanger in an "S" shape. This extends the transit time, increases the heat dissipation contact area, and improves the flow velocity without increasing the overall length, thereby enhancing heat exchange efficiency and achieving rapid cooling.

[0053] As a further embodiment of the present invention, the active central hub includes a beam shroud 9;

[0054] The beam shroud 9 is provided with a spiral plate 94, and the beam shroud 9 abuts against the elastic member 72 when the object being cooled is in an overspeed state.

[0055] Specifically, the beam shroud 9 is installed inside the outlet 3 of the object being cooled and rotates as the water flows through. The faster the water flows through, the greater the rotation speed of the beam shroud 9. When the object being cooled is overspeeding, the beam shroud 9 is also in an overspeeding state. At this time, the beam shroud 9 abuts against the inner wall of the elastic element 72 and drives the elastic element 72 to twist as a whole. The elastic element 72 begins to store energy and drives the partition 7 to rotate. A baffle is set on the end face 15 so that the partition 7 is blocked by the baffle after rotating 120° and automatically stops rotating, reaching the second station. When the water flow rate decreases, the beam shroud 9 no longer abuts against the elastic element 72, so that the deformation energy stored in the elastic element 72 is released, thereby driving the partition 7 to rotate in the opposite direction back to the first station.

[0056] Furthermore, a rotation speed sensor and an electric telescopic rod can be installed inside the beam shroud 9. When the beam shroud 9 exceeds the speed limit, the rotation speed sensor is triggered, thereby driving the electric telescopic rod to extend and press against the elastic member 72. Alternatively, a pressure sensor and an electromagnet can be installed inside the beam shroud 9, and a metal fastener can be installed inside the elastic member 72. When the impact force of the water flow is detected to be too large, the electromagnet is activated, and the metal fastener is attracted and snapped into place by the electromagnet to achieve the abutment. Other driving methods known to those skilled in the art are also acceptable.

[0057] As a further embodiment of the present invention, a locking ball 96 is movably disposed inside the beam shroud 9;

[0058] The port is provided with a drive ring 8 that engages with the locking ball 96, and the drive ring 8 is provided with an external thread 81 that engages with the thread of the partition 7.

[0059] When the locking ball 96 is engaged, the external thread 81 rotates in the opposite direction to the beam shroud 9.

[0060] Specifically, the beam shroud 9 is movably disposed within the drive ring 8. A tension spring 95 is provided on the locking ball 96 inside the beam shroud 9. The tension spring 95 pulls the locking ball 96 with its own elastic force, keeping the locking ball 96 in a retracted state within the beam shroud 9. A fixing tube 71 is provided on the partition 7, and a snap-fit ​​groove 12 for limiting the position of the partition 7 is opened on its end face 15. An internal thread 73 corresponding to the external thread 81 is provided inside the fixing tube 71. The drive ring 8 is a planetary gear set, where the external thread 81 is located at the position of the orbital gear ring. The drive ring 8 is provided with a limiting groove 83 for accommodating the locking ball 96. A planetary gear 84 is provided between the drive ring 8 and the external thread 81. The drive ring 8 and the planetary gear 84, as well as the planetary gear 84 and the external thread 81, are all meshed transmissions.

[0061] When the beam dome 9 rotates at high speed, the centrifugal force generated by the rotation causes the locking ball 96 to extend outward against the elastic force of the tension spring 95. After extending to the outside of the beam dome 9, the locking ball 96 engages with the limiting groove 83, thereby driving the limiting groove 83 to rotate. During the rotation of the limiting groove 83, the planetary gear 84 rotates, which in turn drives the external thread 81 to rotate, and the rotation direction of the external thread 81 is opposite to that of the beam dome 9. The rotation of the external thread 81 engages with the internal thread 73, thereby driving the fixed tube 71 to move along the axial direction. The fixed tube 71 causes the partition 7 to be misaligned from the locking groove 12. When the external thread 81 rotates to a certain angle and reaches the limit position with the internal thread 73, the rotation of the external thread 81 will drive the internal thread 73 to rotate synchronously, thereby causing the partition 7 to rotate. Since the partition 7 is misaligned from the locking groove 12, the locking groove 12 will not obstruct the partition 7.

[0062] When the partition 7 starts to rotate, it causes the elastic element 72 to twist, and the elastic element 72 begins to deform and store energy. Subsequently, when the partition 7 rotates to the second position, it is stopped by the baffle fixed on the end face 15, and the rotation stops. The elastic element 72 releases part of the stored energy, pushing the partition 7 into the snap-fit ​​groove 12. At this time, it has switched from the first heat exchange channel to the second heat exchange channel. When the flow rate of the water decreases, the beam shroud 9 no longer rotates at excessive speed, so that the locking ball 96 is pulled back into the beam shroud 9 by the tension spring 95. At this time, the limiting groove 83 is no longer snapped by the locking ball 96, thereby stopping the planetary gear 84 and the external thread 81 from rotating. The deformation energy of the elastic element 72 is released and drives the partition 7 back to the first position.

[0063] As a further embodiment of the present invention, the beam shroud 9 includes a narrow opening 92 for beam cooling objects and a channel 93 opened on the beam shroud 9, and a piston 91 is disposed in the narrow opening 92;

[0064] The piston 91 is changed in direction by pressure so that the cooled object flows out of the port along the narrow opening 92 or enters the port along the channel 93.

[0065] Specifically, the drive ring 8 is equipped with a baffle 82 for blocking the channel 93, the narrow opening of the beam shroud 9 faces the port, and the piston 91 is provided with shape memory metal to maintain a distance from the narrow opening 92. When water or air flows into the beam shroud 9 along the narrow opening 92, it will first push the piston 91, causing the piston 91 to close the narrow opening 92. At this time, the water or air can only flow along the outer wall of the beam shroud 9. The water or air pushes the beam shroud 9 to slide radially, the baffle 82 no longer blocks the channel 93, and the locking ball 96 is misaligned with the limiting groove 83. At this time, the beam shroud 9 is located inside the cooling object inlet 2, and even if the beam shroud 9 exceeds the speed, it will not drive the drive ring 8.

[0066] When water or air flows out of the narrow opening 92, it aligns the flow hood 9 with the limiting groove 83, and the channel 93 is blocked by the baffle plate 82. At the same time, the water or air will push the piston 91 from the inside, increasing the distance between the piston 91 and the narrow opening 92. At this time, the water or air is concentrated by the narrow opening 92, the flow velocity at the narrow opening 92 increases and the pressure decreases, creating a negative pressure environment at the narrow opening 92, which produces a suction effect on the water or air, resulting in better delivery.

[0067] As another embodiment of the present invention, a rotating tail fin 85 is provided on the external thread 81.

[0068] Specifically, when the beam dome 9 is not overspeeding, the external thread 81 rotates under the action of the rotating tail fin 85 due to the water flow, and the direction of rotation is the same as that of the beam dome 9. When the beam dome 9 rotates at overspeed, the centrifugal force generated by the rotation causes the locking ball 96 to extend outward against the elastic force of the tension spring 95. After the locking ball 96 extends to the outside of the beam dome 9, it engages with the limiting groove 83, thereby driving the limiting groove 83 to rotate. During the rotation of the limiting groove 83, it drives the planetary gear 84 to rotate. At this time, the planetary gear 84 drives the external thread 81 to rotate, and the direction of rotation of the external thread 81 is opposite to that of the beam dome 9. During the rotation of the external thread 81, it engages with the internal thread 73, thereby driving the fixed tube 71 to move along the axial direction. The fixed tube 71 drives the partition 7 to be misaligned from the locking groove 12. When the external thread 81 rotates to a certain angle and reaches the limit position with the internal thread 73, the rotation of the external thread 81 will drive the internal thread 73 to rotate synchronously, thereby causing the partition 7 to rotate. Since the partition 7 is misaligned with the snap-fit ​​groove 12, the snap-fit ​​groove 12 will not block the partition 7.

[0069] As the speed of the beam dome 9 decreases, the locking ball 96, pulled by the tension spring 95, returns to its original position within the beam dome 9. At this point, the limiting groove 83 is no longer engaged by the locking ball 96 and stops rotating. The external thread 81, however, will rotate under the influence of the water flow in the opposite direction to its previous rotation. The external thread 81 will then drive the internal thread 73 to rotate in the opposite direction, and the elastic element 72 will release some of its elastic energy. Upon reaching its limit position, the external thread 81 will no longer drive the internal thread 73 to rotate, causing the threaded connection between the two to loosen. At this point, the internal thread 73 will move the partition 7 closer to the end face 15, and simultaneously, the elastic element 72 will release its elastic energy, causing the partition 7 to return to its first position.

[0070] As a further embodiment of the present invention, it also includes a rubber scraper 75 disposed at the first end of the partition 7, on which an abutment portion 751 is disposed in close contact with the end face 15.

[0071] Specifically, the partition 7 is provided with a locking member 77 for engaging the end face 15, and the rubber scraper 75 is provided with a water collecting plate 753 that abuts against the locking member 77; the contact part 751 is fixedly provided with a blocking part 752 that blocks the water collecting plate 753. The water collecting plate 753 plays a good fixing role during the process of inserting the locking member 77 into the engaging groove 12. Through the elasticity of the water collecting plate 753 itself, it abuts against the guide surfaces 13 on both sides of the engaging groove 12. At this time, the water collecting plate 752 abuts against the blocking part 752, such as... Figure 7 As shown, this design prevents water or airflow from entering. During the cooling process, the airflow may generate a significant amount of condensate. During the switching between the first and second workstations, the baffle 7 uses a rubber scraper 75 to remove the condensate from the end face 15. As the baffle 7 moves, it continuously drives the contact part 751 to abut against the end face. The contact part 751 slightly deforms, scraping away the condensate and allowing it to flow into the baffle part 752. At this time, the baffle part 752 points towards the inside of the water collection plate 753, collecting the condensate and preventing it from stagnating inside the body 1.

[0072] As another embodiment of the present invention, the partition 7 is provided with a plurality of suction pipes 76, and the water collection plate 753 is deflected tangentially to the end face 15 to make the suction pipes 76 unobstructed.

[0073] Specifically, at the first station, the partition 7 drives the rubber scraper 75 to abut against the end face 15. At this time, the rubber scraper 75 is deformed under pressure, which closes the channel between the water collecting plate 753 and the rubber scraper 75. When the partition 7 reaches the second station, the water collecting plate 753 deflects tangentially to the end face 15, so that the end of the water collecting plate 753 abuts against the end face 15. An arc-shaped member 754 is provided between the stop part 752 and the abutting part 751. When the partition 7 switches between the first station and the second station, the movement of the partition 7 will continuously drive the abutting part 751 to abut against the end face. The abutting part 751 slightly deforms and scrapes off the condensed water. The arc-shaped member 754 drives the stop part 752 to deflect, and the arc-shaped member 754 begins to store force. At this time, a gap appears between the baffle 752 and the water collecting plate 753, allowing condensate to flow in. Then, the stored force of the arc-shaped part 754 is released, causing the baffle 752 to deflect and abut against the end of the water collecting plate 753. At the same time, a gap appears between the contact part 751 and the end face 15, and the condensate flows from the end face 15 into the end of the water collecting plate 753, and is then sucked away through the suction pipe 76.

[0074] As another embodiment of the present invention, the second end of the partition 7 opposite to the rubber scraper 75 is provided with a suction port 74 pointing to the narrow opening 92.

[0075] Specifically, the water flow is concentrated by the narrow opening 92, where the flow velocity increases and the pressure decreases, creating a negative pressure environment that draws the water flow away through the suction port 74. A central tube 11 penetrating the main body 1 is also provided on the end face 15. The port of the central tube 11 is located inside the beam shroud 9. When the water flows into the beam shroud 9 along the narrow opening 92, it first pushes the piston 91, causing the piston 91 to close the narrow opening 92. At this time, the water flow can only flow along the outer wall of the beam shroud 9. The water flow pushes against the beam shroud 9 and slides radially. The baffle plate 82 no longer blocks the channel 93. When the water flow enters along the channel 93, it forms a vortex inside the beam shroud 9. This vortex is spiral-shaped, causing air bubbles in the water flow to rotate within it. The air bubbles are then drawn to the other end of the main body 1 through the central tube 11, preventing uneven heating of the air bubbles within the straight tube 14.

[0076] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
