[0039] In order 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 tubes 14 penetrating and arranged at both ends of the body 1, including a port arranged at the end of the body 1, and the port is divided into a cooling object inlet 2 and a cooling object outlet 3 according to function;

[0041] End surfaces 15 are fixedly arranged at both ends of the body 1 and are arranged with the same cross section as the end of the straight pipe 14;

[0042] The partition 7 disposed on the end surface 15 has adjacent surfaces enclosed to form a conveying space connected to the cooling object inlet 2\cooling object outlet 3, and the back surfaces of the partition 7 are connected to the straight pipe 14.

[0043] A movable hub for driving the partition plate 7 to rotate, comprising an elastic member 72 disposed between the partition plate 7 and the body 1;

[0044] There are two positions in the activity stroke of the partition 7:

[0045] In the first station, the elastic member 72 is unfolded, and the conveying spaces at both ends correspond to each other to form a first heat exchange channel for the cooling object to pass quickly;

[0046] At the second station, the elastic member 72 is twisted, and the conveying spaces at both ends are staggered to form a second heat exchange channel for the cooling object to flow in an S shape.

[0047] Specifically, the end surface 15 is evenly divided into three parts, ABC, such as Fig.10As shown, the ports facing the cooling object inlet 2 are A1, B1 and C1, and the ports facing the cooling object outlet 3 are A2, B2 and C2, wherein the cooling object inlet and outlet are relatively arranged, that is, the ports at both ends of the body 1 are not divided into inlet and outlet. It also includes a cooling medium inlet 4 and a cooling medium outlet 5 for conveying cooling medium, which are used to cool and dissipate heat for the straight pipe 14.

[0048] Furthermore, the partition 7 divides the end surface 15 into a conveying space and a communication space. Figure 2 The figure is for reference only. 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 through the straight pipe 14 to form a 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 has a faster flow time in the straight pipe 14 and a shorter contact time with the cooling medium. It is suitable for slow-flowing cooling objects and reduces the cooling time.

[0049] When the partition 7 reaches the second station, A1 is still the conveying space at the inlet 2 of the cooling object, B1 is connected to C1, and B2 or C2 is 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, C2 to C1, and then enters B1 through the connecting space, and finally enters B2 from B1, making the path S-shaped, and the same is true when C2 is the conveying space. This is the second heat exchange channel, which will not be repeated. By achieving multiple round trips of the cooling object without lengthening the main body 1, the effect of sufficient heat dissipation is achieved.

[0050] When the flow rate of the cooling object in the first heat exchange channel is too fast, in order to improve the heat exchange efficiency, the partition 7 is driven to rotate 120° through the control center, thereby switching from the first heat exchange channel to the second heat exchange channel. During the rotation process, since the two ends of the elastic member 72 are respectively fixedly connected to the main body 1 and the partition 7, one section of the elastic member 72 is twisted during the rotation of the partition 7.

[0051] The control center in the above technology can set 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 driven to rotate to a specified angle by a driving motor or a turbine structure, or a temperature measuring unit is set at the outlet 3 of the cooling object. When the temperature reduction range is too low, the driving motor or the turbine structure drives the partition 7 to rotate, or other methods known to technical personnel in this field are also possible.

[0052] In the above technology, the cooling object is detected through the control center, and the cooling object with slow flow is cooled through the first heat exchange channel to reduce the time required for cooling. The cooling object with fast flow enters the second heat exchange channel, and then flows back and forth inside the heat exchanger in an "S" shape. Without increasing the length, the passing time is extended, the heat dissipation contact area is increased, and the flow speed is increased, so as to improve the heat exchange efficiency and achieve the purpose of rapid cooling.

[0053] As an embodiment further provided by the present invention, the movable hub includes a beam shield 9;

[0054] A spiral plate 94 is provided in the beam cover 9, and the beam cover 9 abuts against the elastic member 72 when the cooling object is in an overspeed state.

[0055] Specifically, the beam hood 9 is arranged in the outlet 3 of the cooling object and rotates as the water flows through. The faster the water flows through, the greater the rotation speed of the beam hood 9. When the cooling object exceeds the speed, the beam hood 9 is also in an overspeed rotation state. At this time, the beam hood 9 abuts against the inner wall of the elastic member 72 and drives the elastic member 72 to twist as a whole. The elastic member 72 begins to accumulate force and drives the partition 7 to rotate. A baffle is set on the end face 15, so that the baffle 7 is automatically stopped by the baffle after rotating 120° and reaches the second station. When the flow rate of the water flow decreases, the beam hood 9 does not abut against the elastic member 72, so that the deformation energy accumulated in the elastic member 72 is released, thereby driving the baffle 7 to rotate in the opposite direction back to the first station.

[0056] Furthermore, a speed sensing device and an electric telescopic rod can be arranged in the beam cover 9. When the beam cover 9 exceeds the speed limit, the speed sensing device 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 arranged in the beam cover 9, and a metal fastener can be arranged in the elastic member 72. When it is detected that the impact force of the water flow is too large, the electromagnet is started, and the metal fastener is attracted by the electromagnet and clamped to achieve abutment. Alternatively, other driving methods known to those skilled in the art are also possible.

[0057] As another embodiment further provided by the present invention, a locking ball 96 is movably provided in the beam cover 9;

[0058] A driving ring 8 is provided in the port to engage with the locking ball 96, and an external thread 81 is rotatably provided on the driving ring 8 to engage with the thread of the partition plate 7;

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

[0060] Specifically, the beam cover 9 is movably arranged in the driving ring 8. A tension spring 95 is arranged on the locking ball 96 in the beam cover 9, and the tension spring 95 pulls the locking ball 96 through its own elastic force, so that the locking ball 96 remains in the state of being retracted in the beam cover 9. A fixing tube 71 is arranged on the partition 7, and a clamping groove 12 for limiting the position of the partition 7 is opened on the end face 15, and an internal thread 73 corresponding to the external thread 81 is arranged in the fixing tube 71. The driving ring 8 is a planetary gear set, wherein the position of the external thread 81 is a track gear ring, and a limiting groove 83 for accommodating the locking ball 96 is arranged on the driving ring 8, and a planetary gear 84 is arranged between the driving ring 8 and the external thread 81, and the driving ring 8 and the planetary gear 84, and the planetary gear 84 and the external thread 81 are all meshing transmission.

[0061] When the beam shield 9 rotates at an overspeed, the centrifugal force generated by the rotation causes the locking ball 96 to extend outward to overcome the elastic force of the tension spring 95. After the locking ball 96 extends to the outside of the beam shield 9, it engages with the limit groove 83, thereby driving the limit groove 83 to rotate. During the rotation of the limit groove 83, the planetary gear 84 is driven to rotate. At this time, the planetary gear 84 drives the external thread 81 to rotate, and the rotation direction of the external thread 81 is opposite to that of the beam shield 9. The rotation process of the external thread 81 cooperates with the internal thread 73, thereby driving the fixed tube 71 to move along the axial diameter direction, and the fixed tube 71 drives the partition 7 to stagger with the clamping groove 12. When the external thread 81 rotates 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 rotating the partition 7, and because the partition 7 is staggered with the clamping groove 12, the clamping groove 12 will not block the partition 7.

[0062] When the partition 7 starts to rotate, it drives the elastic member 72 to twist, and the elastic member 72 starts to deform and accumulate force. Then, when the partition 7 rotates to the second position, it is stopped by the baffle fixed on the end face 15, stops rotating, and the elastic member 72 releases part of the accumulated force, pushing the partition 7 into the clamping groove 12, and the first heat exchange channel is switched to the second heat exchange channel. When the flow rate of the water flow decreases, the beam cover 9 no longer rotates at an overspeed, so that the locking ball 96 is pulled back into the beam cover 9 by the tension spring 95. At this time, the limit groove 83 is no longer clamped by the locking ball 96, so that the planetary gear 84 and the external thread 81 stop rotating, and the deformation of the elastic member 72 is released and drives the partition 7 to return to the first position.

[0063] As another embodiment further provided by the present invention, the beam cover 9 includes a narrow opening 92 for the beam cooling object and a channel 93 opened on the beam cover 9, and a piston 91 is arranged in the narrow opening 92;

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

[0065] Specifically, the driving ring 8 is provided with a baffle 82 for blocking the channel 93, the narrow opening of the beam cover 9 faces the port, and the piston 91 is provided with a memory metal to keep a distance from the narrow opening 92. When the water flow or air flow flows into the beam cover 9 along the narrow opening 92, it will first squeeze the piston 91, so that the piston 91 closes the narrow opening 92. At this time, the water flow or air flow can only flow along the outer wall of the beam cover 9, and the water flow or air flow pushes the beam cover 9 to slide radially. The baffle 82 no longer blocks the channel 93, and the locking ball 96 is staggered from the limit groove 83. At this time, the beam cover 9 is located in the cooling object inlet 2, and even if the beam cover 9 exceeds the speed, it will not drive the driving ring 8.

[0066] When the water flow or air flow flows out of the narrow opening 92, the beam shield 9 is driven to align with the limiting groove 83, and the channel 93 is blocked by the baffle 82. At the same time, the water flow or air flow will push the piston 91 from the inside, so that the distance between the piston 91 and the narrow opening 92 is increased. At this time, the water flow or air flow is bundled by the narrow opening 92, the flow velocity at the narrow opening 92 is accelerated and the pressure is reduced, so that a negative pressure environment is formed at the narrow opening 92, which produces a suction effect on the water flow or air flow, so that the conveying effect is better.

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

[0068] Specifically, when the spar 9 is not overspeeding, the external thread 81 rotates under the action of the rotating tail wing 85 and is washed by the water flow, and the rotation direction is consistent with the spar 9. When the spar 9 rotates at an overspeed, the centrifugal force generated by the rotation causes the locking ball 96 to overcome the elastic force of the tension spring 95 and extend outward. After the locking ball 96 extends to the outside of the spar 9, it engages with the limit groove 83, thereby driving the limit groove 83 to rotate. During the rotation of the limit groove 83, the planetary gear 84 is driven to rotate. At this time, the planetary gear 84 drives the external thread 81 to rotate, and the rotation direction of the external thread 81 is opposite to that of the spar 9. During the rotation process, the external thread 81 cooperates with the internal thread 73, thereby driving the fixed tube 71 to move along the axial diameter direction, and the fixed tube 71 drives the partition 7 to stagger with the engaging groove 12. When the external thread 81 rotates 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. Moreover, since the partition 7 is staggered with the snap-in groove 12, the snap-in groove 12 will not block the partition 7.

[0069] When the speed of the beam shield 9 decreases, the locking ball 96 is pulled back into the beam shield 9 by the tension spring 95. At this time, the limit groove 83 is no longer engaged by the locking ball 96, and the limit groove 83 stops rotating. The external thread 81 will rotate under the action of the water flow, and the rotation direction is opposite to that before. The external thread 81 will drive the internal thread 73 to rotate in the opposite direction, and the elastic member 72 releases part of the elastic energy. After reaching the limit position, the external thread 81 no longer drives the internal thread 73 to rotate, and the threaded connection between the two begins to loosen. At this time, the internal thread 73 drives the partition 7 to approach the end face 15, and the elastic member 72 releases the elastic energy, so that the partition 7 returns to the first position.

[0070] As another embodiment further provided by the present invention, the present invention further comprises a rubber scraper 75 disposed at the first end of the partition 7 , on which a resisting portion 751 tightly attached to the end surface 15 is disposed.

[0071] Specifically, the partition 7 is provided with a clamping member 77 for clamping the end surface 15, and the rubber scraper 75 is provided with a water collecting plate 753 that abuts against the clamping member 77; the abutting portion 751 is fixedly provided with a blocking portion 752 that abuts against the water collecting plate 753. The water collecting plate 753 plays a good fixing role in the process of inserting the clamping member 77 into the clamping groove 12. The elastic force of the water collecting plate 753 abuts against the guide sliding surfaces 13 on both sides of the clamping groove 12. At this time, the water collecting plate 752 abuts against the blocking portion 752, as shown in FIG. Figure 7 As shown, water or air flow can be prevented from entering. The air flow may generate more condensed water during the cooling process. During the switching process between the first station and the second station, the partition 7 scrapes the condensed water on the end surface 15 through the rubber scraper 75. When the partition 7 moves, it will continuously drive the abutment part 751 to abut against the end surface. The abutment part 751 slightly deforms to scrape the condensed water and make the condensed water flow into the blocking part 752. At this time, the blocking part 752 points to the inside of the water collecting plate 753 to collect the condensed water and prevent the condensed water from being retained in the main body 1.

[0072] As another embodiment further provided by the present invention, a plurality of suction pipes 76 are arranged inside the partition 7, and the water collecting plate 753 is tangent to the end surface 15 and deflected downward to make the suction pipes 76 unobstructed.

[0073] Specifically, the partition 7 at the first station drives the rubber scraper 75 to abut against the end surface 15. At this time, the rubber scraper 75 is deformed under pressure, so that the channel between the water collecting plate 753 and the rubber scraper 75 is closed. When the partition 7 reaches the second station, the water collecting plate 753 deflects downward tangent to the end surface 15, so that the end of the water collecting plate 753 abuts against the end surface 15. An arc-shaped member 754 is arranged between the blocking portion 752 and the abutting portion 751. When the partition 7 switches between the first station and the second station, the partition 7 will continuously drive the abutting portion 751 to abut against the end surface when it moves. The abutting portion 751 slightly deforms to scrape the condensed water, and the blocking portion 752 is deflected by the arc-shaped member 754, and the arc-shaped member 754 begins to accumulate force. At this time, a gap appears between the blocking portion 752 and the water collecting plate 753, allowing condensed water to flow in. Subsequently, the stored force of the arc-shaped member 754 is released, causing the blocking portion 752 to deflect and abut against the end of the water collecting plate 753, while causing a gap to appear between the abutting portion 751 and the end face 15. The condensed water 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 further provided by the present invention, a second end of the partition plate 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 bundled by the narrow opening 92, the flow velocity at the narrow opening 92 is accelerated and the pressure is reduced, so that a negative pressure environment is formed at the narrow opening 92, which produces a suction effect on the water flow, thereby sucking away the liquid in the suction tube 76 through the suction port 74. A central tube 11 that runs through the body 1 is also provided on the end surface 15, and the port position of the central tube 11 is located inside the beam cover 9. When the water flow flows into the beam cover 9 along the narrow opening 92, it will first squeeze the piston 91, so that the piston 91 closes the narrow opening 92. At this time, the water flow can only flow along the outer wall of the beam cover 9, and the water flow pushes the beam cover 9 to slide radially. The baffle 82 no longer blocks the channel 93. When the water flow enters along the channel 93, a vortex will be formed inside the beam cover 9. The vortex is spiral, which will cause the bubbles in the water flow to rotate in the vortex. At this time, the bubbles are sucked to the other end of the body 1 through the central tube 11 to avoid uneven heating caused by the bubbles in the straight tube 14.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
