Description

Technical Field

[0001] The present invention relates to the field of heat exchange technology, and in particular to a baffle support structure and a heat exchanger. Background Art

[0002] The heat exchanger uses the heat transfer phenomenon to transfer the heat of medium A to medium B, thereby realizing the conversion of thermal energy. The baffle is the core component of the heat exchanger. It guides the medium A through staggered arrangement, thereby increasing the flow path of medium A in the heat exchanger and ensuring the heat exchange effect.

[0003] After searching, the Chinese patent publication number CN218723465U discloses a heat exchanger baffle support structure and a heat exchanger, including a heat exchanger baffle support structure including an arc-shaped support rod, a tie rod, and a muffler assembly and a support plate arranged perpendicularly to each other, the muffler assembly is used to be arranged vertically on the baffle of the heat exchanger and / or the tube sheet of the heat exchanger, both ends of the arc-shaped support rod are connected to the side wall of the support plate, and the plane where the arc-shaped support rod is located is arranged perpendicularly to the muffler assembly. The tie rod is connected to the arc-shaped support rod, and both ends of the tie rod are connected to the baffle and the tube sheet respectively.

[0004] The above patent has the following deficiencies: the angle of the baffle cannot be adjusted, which makes the guiding effect of the baffle on the medium in a constant state.

DETAILED DESCRIPTION

[0033] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] Embodiment 1:

[0036] A baffle support structure, such as Figure 1 As shown, it includes a fixed rod 1 and a fixed rod 2 8 which are rotatably connected to the baffle 4 through a rotating shaft 2. The baffle 4 is provided with a strip groove 6 inside. The same movable rod 5 runs through all the strip grooves 6. A rotating shaft 2 9 is fixed to the side wall of the movable rod 5. The side wall of the strip groove 6 is provided with a sliding groove 7 which cooperates with the rotating shaft 2 9 for movable limiting.

[0037] When this embodiment is in use, when the inflow temperature of the medium is low, the movable rod 5 is moved axially so that the rotating shaft 9 limits the strip groove 6, thereby driving the baffle 4 to rotate in the same direction relative to the fixed rod 1 and the fixed rod 8, so that the projected area of ​​the baffle 4 along the vertical plane is reduced, the overlap between adjacent baffles 4 is reduced, the resistance to the medium is reduced, and the relative flow speed of the medium is faster, otherwise it is slower.

[0038] The device connects the baffle 4 by setting a fixed rod 1 and a fixed rod 2 8, and then limits the baffle 4 by a movable rod 5, so that the angle of the baffle 4 can be adjusted according to the actual temperature of the medium, thereby adjusting the overlap between the baffles 4 and adjusting the resistance of the baffle 4 to the medium, so that the flow path of the medium matches the temperature, ensuring the heat exchange effect while achieving energy saving effect.

[0039] Embodiment 2:

[0040] A heat exchanger, such as Figure 2-8 As shown, it includes the baffle support structure in Example 1, and also includes a box body 10 and end covers 17 fixed to both sides of the box body 10 by bolts, a fixing rod 1 and a fixing rod 8 are fixed to the opposite side of the end cover 17, a movable rod 5 is slidably connected to the inner side of the end cover 17, and the interior of the box body 10 is also provided with a tube array 14 for another medium to flow, and the two ends of the tube array 14 are respectively connected to a medium B multi-way inlet 13 and a medium B multi-way outlet 15, the side walls of the two end covers 17 are respectively provided with a medium A outlet 11 and a medium A inlet 16, and the outer wall of one of the end covers 17 is provided with a fluid integrated driving mechanism 12.

[0041] The fluid integrated driving mechanism 12 can drive two media to flow at the same time, one of which is sucked in from the medium A inlet 16 and flows along the inner cavity of the box 10 and the gap between the baffles 4, and the other is sent in from the medium B multi-channel inlet 13 and flows along the tube array 14. During the flow process, the two media exchange heat. After the heat exchange, one of the media flows out from the medium A outlet 11, and the other flows out from the medium B multi-channel outlet 15.

[0042] In order to solve the problem of automatic path adjustment, such as Figure 3 As shown, a pleated telescopic airbag 18 is fixed to the side wall of one of the end covers 17, a convex disc 19 is fixed to the other end of the pleated telescopic airbag 18, the convex disc 19 is fixed to the outer wall of the movable rod 5, the other end of the movable rod 5 is fixed to a convex disc 21 by bolts, the side wall of the convex disc 21 is buckled with a spring 20, and the other end of the spring 20 is buckled to the outer wall of the other end cover 17.

[0043] When the temperature of the medium entering the medium A inlet 16 is high, the pleated telescopic airbag 18 will also exchange heat with the medium, so that the temperature of the inner cavity increases, and the gas inside it expands due to the heat, thereby applying an elastic force to the convex plate 19. The movable rod 5 overcomes the elastic force of the spring 20 and moves axially. At this time, the baffle 4 moves from an inclined state to a vertical state, increasing the overlap between the baffles 4, increasing the resistance, and reducing the flow rate. When the medium temperature is low, the movable rod 5 drives the baffle 4 to rotate in the direction of a higher inclination, reducing the resistance and increasing the flow rate.

[0044] The device is provided with a pleated telescopic airbag 18, which again utilizes "heat exchange" and combines the thermal expansion and contraction characteristics of the gas, so that it can automatically adjust the position of the movable rod 5 according to the temperature of the medium flowing into the medium A inlet 16, thereby adjusting the angle of the baffle 4 and realizing the function of adaptively adjusting the flow path according to the temperature.

[0045] To solve fluid drive problems, such as Figure 4 As shown, the fluid integrated driving mechanism 12 includes a fixed shell 29 fixed to the side wall of the end cover 17 and an elastic hose 1 25 and an elastic hose 26 bonded to the inner wall of the fixed shell 29. The elastic hose 1 25 is connected to the multi-way inlet 13 of medium B, and the elastic hose 26 is connected to the outlet 11 of medium A. Specifically, the other end of the elastic hose 1 25 and the multi-way outlet 15 of medium B can be connected to the storage part of one of the media, and the other end of the elastic hose 26 and the medium A inlet 16 can be connected to the storage part of another medium, forming a circulating heat exchange structure.

[0046] The inner wall of the fixed shell 29 is rotatably connected to a driving shaft 28, and the outer wall of the driving shaft 28 is rotatably connected to a plurality of rollers 24. The rollers 24 are in contact with and squeezed with the elastic hose 1 25 and the elastic hose 2 26. The end of the fixed shell 29 is fixed with a motor 27 by bolts, and the output end of the motor 27 is connected to the end of the driving shaft 28 by a coupling.

[0047] When the motor 27 is started, it can drive the driving shaft 28 to rotate, thereby driving the roller 24 to roll along the elastic hose 1 25 and the elastic hose 2 26, squeezing the elastic hose 1 25 and the elastic hose 2 26 to squeeze out the medium in the elastic hose 1 25 and the elastic hose 2 26. After squeezing, the elastic hose 1 25 and the elastic hose 2 26 rebound due to their own elastic deformation, thereby utilizing the rebound negative pressure to suck the medium, forming a fluid conveying effect.

[0048] This device, by setting the fluid integrated driving mechanism 12 as a combination of a roller 24, an elastic hose 1 25, and an elastic hose 2 26, can, on the one hand, allow two heat exchange media to be transported simultaneously, thereby reducing the number of pump components to be set; on the other hand, it can also synchronize the transport speeds of the two media to ensure the heat exchange effect. At the same time, the opening and closing of the transport is also comprehensively controlled by the motor 27, thereby simplifying the control logic.

[0049] The motor 27 includes a coaxially fixed housing 1 30 and a housing 2 31 , an electromagnetic drive assembly 32 is disposed inside the housing 2 31 , and a power adjustment assembly 33 is disposed inside the housing 1 30 .

[0050] The electromagnetic drive assembly 32 includes a main shaft 36 rotatably connected to the inner wall of the shell 2 31 and a rotor core 35 fixed to the outer wall of the main shaft 36. The outer side of the rotor core 35 is used in conjunction with a stator winding 34, and the stator winding 34 is axially slidably connected to the inner wall of the shell 2 31 through a guide rod 37.

[0051] When the stator winding 34 is energized, the rotor core 35 can be rotated, thereby driving the main shaft 36 to rotate and perform external work. The higher the overlap between the stator winding 34 and the rotor core 35, the higher the matching power, which makes the rotation power of the rotor core 35 higher and the external work power greater. Therefore, by controlling the lateral movement of the stator winding 34 to control the overlap between the stator winding 34 and the rotor core 35, the output power of the main shaft 36 can be controlled.

[0052] The power adjustment assembly 33 includes an electromagnet 3 and a permanent magnet 39, wherein the electromagnet 3 is fixed to the inner wall of the housing 1 30, the permanent magnet 39 is fixed to the end of the guide rod 37, and a spring 2 38 is buckled on the side wall of the permanent magnet 39, and the other end of the spring 2 38 is buckled on the side wall of the housing 2 31;

[0053] When the current intensity of the electromagnet 3 changes, the intensity of the magnetic field it generates will also change, thereby interacting with the permanent magnet 39, and cooperating with the spring 2 38 to move the permanent magnet 39, thereby moving the stator winding 34.

[0054] A semiconductor electrode A22 is fixedly embedded in the inner wall of the medium B multi-channel outlet 15, and a semiconductor electrode B23 is fixedly embedded in the inner wall of the medium A outlet 11. The semiconductor electrode A22 and the semiconductor electrode B23 are respectively connected to the connection terminals of the electromagnet 3.

[0055] When there is a temperature difference between the two media when they flow out, it means that the heat exchange between the two media is not complete, so at this time the semiconductor electrode A22 and the semiconductor electrode B23 will sense the temperature and use the temperature difference to generate an electromotive force, which is then applied to the electromagnet 3, so that the electromagnet 3 generates a field strength. The greater the temperature difference, the higher the electromotive force generated between the semiconductor electrode A22 and the semiconductor electrode B23, thereby making the field strength generated by the electromagnet 3 greater, the lower the overlap between the stator winding 34 and the rotor core 35, the smaller the output power, and the slower the flow rate.

[0056] This device, through targeted design of the motor 27, utilizes the relationship between temperature difference and heat exchange thoroughness, and combines the principle of temperature difference power generation, so that the conveying speed of the motor 27 for the medium can be automatically adjusted according to the output temperature difference of the two media.

[0057] When the motor 27 of this embodiment is started during use, it can drive the driving shaft 28 to rotate, thereby driving the roller 24 to roll along the elastic hose 1 25 and the elastic hose 2 26, squeezing the elastic hose 1 25 and the elastic hose 2 26, and squeezing out the medium in the elastic hose 1 25 and the elastic hose 2 26. After squeezing, the elastic hose 1 25 and the elastic hose 2 26 are subjected to their own elastic deformation and rebound, thereby utilizing the rebounding negative pressure to suck the medium, thereby forming a fluid conveying effect. One of the media is sucked in from the medium A inlet 16, and flows along the inner cavity of the box body 10 and the gap between the baffle 4. The other medium is fed in from the medium B multi-pass inlet 13, and flows along the tube array 14. During the flow process, the two media exchange heat. After the heat exchange, one of the media flows out from the medium A outlet 11, and the other flows out from the medium B multi-pass outlet 15. When the temperature of the medium entering the medium A inlet 16 is high, the pleated telescopic airbag 18 will also exchange heat with the medium. As a result, the temperature of the inner cavity increases, and the gas inside it expands due to the heat, thereby applying an elastic force to the convex disk 19. The movable rod 5 overcomes the elastic force of the spring 20 and moves axially. At this time, the baffle 4 moves from an inclined state to a vertical state, increasing the overlap between the baffles 4, increasing the resistance, and reducing the flow rate. When the temperature of the medium is low, the movable rod 5 drives the baffle 4 to rotate in a direction with a higher inclination, reducing the resistance and increasing the flow rate. When there is a temperature difference when the two media flow out, it means that the heat exchange between the two media is not thorough. Therefore, at this time, the semiconductor electrode A22 and the semiconductor electrode B23 will sense the temperature and use the temperature difference to generate an electromotive force, which is then applied to the electromagnet 3, so that the electromagnet 3 generates a field strength. The greater the temperature difference, the higher the electromotive force generated between the semiconductor electrode A22 and the semiconductor electrode B23, thereby making the field strength generated by the electromagnet 3 greater, the lower the overlap between the stator winding 34 and the rotor core 35, the smaller the output power, and the slower the flow rate.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
