Description

Technical Field

[0001] The present invention relates to the technical field of heat exchange equipment, and particularly relates to a new type of high-efficiency and low-resistance heat exchanger. Background Art

[0002] A low-resistance heat exchanger is a specially designed heat exchange device. Its core purpose is to reduce the fluid flow resistance while ensuring efficient heat transfer. Its working principle is mainly based on heat conduction. In the internal structure of the heat exchanger, heat is first adsorbed by the solid partition wall, and the cooling fluid is cleverly separated from the solid partition wall that has adsorbed heat. Subsequently, heat is efficiently transferred to the flowing low-temperature fluid through the partition wall as a medium, thereby realizing heat exchange.

[0003] However, in the existing heat exchange technology, the circulation of the cooling fluid usually depends on flow channels with a fixed capacity. The original design intention of these channels is to guide the cooling fluid to flow through the heat exchanger orderly so as to conduct sufficient heat exchange with the solid partition wall that has adsorbed heat. However, in actual applications, such flow channels with a fixed capacity often expose the problem of insufficient heat exchange efficiency when facing a high-temperature heat exchange environment.

[0004] Specifically, when the heat exchange process involves high-temperature fluids, the fixed-capacity flow channels may, due to factors such as uneven fluid flow velocity and temperature distribution, lead to uneven heat transfer, thereby affecting the overall heat exchange effect. In addition, due to the fixed channel capacity, it is difficult to make flexible adjustments according to actual needs, which also limits the adaptability and heat exchange performance of the heat exchanger in high-temperature environments. Summary of the Invention

[0005] The purpose of the present invention is to propose a solution to solve the problem that when the heat exchange process involves high-temperature fluids, the fixed-capacity flow channels may, due to factors such as uneven fluid flow velocity and temperature distribution, lead to uneven heat transfer, thereby affecting the overall heat exchange effect. In addition, due to the fixed channel capacity, it is difficult to make flexible adjustments according to actual needs, which also limits the adaptability and heat exchange performance of the heat exchanger in high-temperature environments.

[0006] To achieve the above purpose, the present invention adopts the following technical solution: a new type of high-efficiency and low-resistance heat exchanger, including a frame body, and further including: a heat exchange component and an adjustment component assembled inside the frame body; The heat exchange component includes a heat exchange element installed on the outer periphery of the frame body, and a fixed cylinder fixedly connected inside the frame body. The fixed cylinder is rotationally connected with a rotating plate through a rotating groove opened at the top, and a baffle is fixedly connected to the outer periphery of the rotating plate. A closing plate is in contact with the outer peripheries of the fixed cylinder and the rotating plate. A liquid inlet is opened inside the baffle, and the liquid inlet is connected to the heat exchange element through a flow channel. There is liquid in the cavity formed between the fixed cylinder and the frame body, and the frame body heats the liquid to vaporize it through heat conduction; The adjusting component includes a floating plate disposed in the cavity and rising with the vaporization of the liquid. The rotating plate and the floating plate are connected by a rotating member. When the floating plate rises, it jacks up the rotating member to rotate the baffle plate, so as to adjust the distance between the baffle plate and the closing plate and expand the heat conduction area of the heat exchange component.

[0007] As a further description of the above technical solution: The rotating member includes a connecting plate slidably connected to the inner wall of the fixed cylinder, and the bottom of the connecting plate is in contact with the top of the floating plate. The top of the connecting plate is fixedly connected with an extension column. An engaging column is installed on the outer periphery of the extension column. The inner wall of the fixed cylinder is fixedly connected with a fixed cylinder, and a spiral groove in contact with the engaging column is provided inside the installation cylinder. And a telescopic member is installed at the top of the extension column.

[0008] As a further description of the above technical solution: The telescopic member includes a multi-section telescopic plate fixedly connected to the top of the extension column, and a multi-section telescopic groove is provided inside the multi-section telescopic plate. The bottom of the rotating plate is connected to the multi-section telescopic plate.

[0009] As a further description of the above technical solution: A mixing component is installed inside the baffle plate. The mixing component includes an installation column rotatably installed on the inner wall of the liquid inlet, and a number of rotating plates are connected to the outer periphery of the installation column.

[0010] As a further description of the above technical solution: The mixing component further includes a number of slots opened inside the frame body. A positioning column is fixedly connected between the inner walls of the slots, and a dial plate is connected to the outer periphery of the positioning column through a torsion spring. The dial plate is in contact with the baffle plate.

[0011] As a further description of the above technical solution: An expansion component is installed inside the frame body. The expansion component includes a welding plate fixedly connected inside the frame body and a support frame. An arc-shaped rod is slidably connected inside the support frame, and the two ends of the arc-shaped rod are respectively connected with a closing plate and a connecting plate. A driving source is installed between the connecting plate and the welding plate.

[0012] As a further description of the above technical solution: The driving source includes a fixed frame fixedly connected to one side of the welding plate. A positioning rod is installed between the inner walls of the fixed frame, and a rotating sleeve rod is rotatably connected to the outer periphery of the positioning rod. A limiting rod is fixedly connected between the inner walls of the connecting plate, and a rotating sleeve rod is rotatably connected to the outer periphery of the limiting rod. And an electric push rod is installed between the rotating sleeve rod and the rotating sleeve rod.

[0013] As a further description of the above technical solution: The ends of the closing plate that fit with the fixed tube and the rotating plate are configured to fit with arc angles of the fixed tube and the rotating plate, and one end of the closing plate that fits with the inner wall of the frame is also configured to fit with an arc angle.

[0014] As a further description of the above technical solution: The frame body comprises a mounting frame, a mounting plate is installed on the top of the mounting frame, and a fan is installed on the bottom of the mounting plate.

[0015] As a further description of the above technical solution: The heat exchange element comprises a water pump installed on the top of the mounting frame, one end of the water pump is connected with a connecting pipe, and the other end of the connecting pipe is communicated with the mounting frame, and a loading box is installed in the middle section of the connecting pipe.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: In order to efficiently exchange heat, the mounting frame needs to fit closely to the heat generating part of the machine to effectively absorb and conduct heat. After starting the water pump, the heat exchange fluid in the loading box is introduced into the mounting frame through the connecting pipe, and circulates along the preset flow channel through the closed space constructed by the baffle and the closing plate to form a complete loop, efficiently absorbing heat and protecting the machine from high temperature damage. When the temperature of the machine is too high, the liquid in the cavity of the mounting frame will evaporate and push the floating plate and the connecting components to rise and rotate, dynamically adjust the distance between the baffle and the closing plate, expand the heat exchange area, and significantly improve the heat exchange efficiency. When the machine stops working, the vaporized liquid cools and condenses, the floating plate drops, returns to the initial state, and removes the residual liquid at the same time; In order to further optimize the heat exchange effect, the following measures are taken: first, the flow of heat exchange fluid is used to drive the rotating component to rotate, stir the liquid, and even out the temperature; second, the baffle plate is squeezed when it rotates, and the torsion spring rebounds to drive the paddle plate to swing, increase liquid mixing, and improve temperature uniformity. When the spacing increases, the number of paddles increases, and the effect is more significant; third, part of the fluid collides with the main fluid through the gap between the paddle plates to improve the overall uniformity; When the machine temperature is constant but the heat exchange efficiency needs to be increased, start the electric push rod, pull the connecting plate and the arc rod to move, increase the distance between the closing plate and the baffle, increase the heat exchange area, and further improve the heat exchange efficiency.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0020] As Figures 1 - 9 shown, a new type of high-efficiency and low-resistance heat exchanger provided by the present invention includes a frame body 10. The frame body 10 includes a mounting frame 11. The top of the mounting frame 11 is internally provided with a mounting plate 12. A fan 13 is installed at the bottom of the mounting plate 12. It further includes: a heat exchange component 20 and an adjusting component 30 assembled inside the mounting frame 11; When heat exchange is required, the mounting bracket 11 can be properly installed on the machine that needs heat exchange to ensure that the mounting bracket 11 is closely attached to the heat-generating part of the machine. In this way, the mounting bracket 11 can effectively absorb and conduct the heat generated by the heat exchange machine.

[0021] As Figure 1 , Figure 2 , Figure 3 , Figure 5 shown, the heat exchange assembly 20 includes a heat exchanger installed on the outer periphery of the mounting bracket 11. The heat exchanger includes a water pump 21 installed on the top of the mounting bracket 11. One end of the water pump 21 is connected to a connecting pipe 22, and the other end of the connecting pipe 22 communicates with the mounting bracket 11. A loading box 23 is installed in the middle section of the connecting pipe 22, and a fixed cylinder 24 fixedly connected inside the mounting bracket 11. The fixed cylinder 24 is rotatably connected to a rotating plate 241 through a rotating groove 244 opened at the top, and a baffle 242 is fixedly connected to the outer periphery of the rotating plate 241. A closing plate 243 abuts against the outer periphery of the fixed cylinder 24 and the rotating plate 241. A liquid inlet 25 is opened inside the baffle 242, and the liquid inlet 25 is connected to the water pump 21 through a flow passage 251. There is a liquid in the cavity formed between the fixed cylinder 24 and the frame 10. The types of the liquid include but are not limited to ether, acetone, water, etc. The type of the liquid is adjusted according to the heat dissipation temperature of the machine to be heat-exchanged. The frame 10 heats the liquid through heat conduction to vaporize it; It should be noted that the liquid in the cavity is not completely filled. The lowest position where the floating plate 31 descends is above the liquid level, leaving a space between the liquid level and the floating plate 31. Through this design, a large thrust is generated on one side of the floating plate 31 after the liquid vaporizes, forming a pressure difference conducive to the movement of the floating plate 31. This pressure difference is conducive to pushing the floating plate 31 to move in the cavity; After the mounting bracket 11 effectively adsorbs heat, by starting the water pump 21, the heat exchange fluid in the loading box 23 is guided through the connecting pipe 22 into the inside of the mounting bracket 11. During this process, the baffle 242 and the closing plate 243 in the mounting bracket 11 jointly construct a closed space, forcing the heat exchange fluid to enter its inside through the preset liquid inlet 25 on the baffle 242. Subsequently, the heat exchange fluid continuously flows along the preset flow passage 251 and finally returns to the water pump 21, forming a complete circulation loop. In this closed space, the heat exchange fluid effectively absorbs the heat in the area between the baffle 242 and the closing plate 243, thereby performing efficient heat exchange on the mounting bracket 11 and effectively preventing the heat exchange machine from being damaged due to excessive temperature.

[0022] As Figure 1 , Figure 2 , Figure 3 , Figure 4As shown in the figure, the adjusting component 30 includes a floating plate 31 disposed in the cavity and rising as the liquid vaporizes. A sealing ring is connected between the floating plate 31 and the fixed cylinder 24. Through this design, ether, acetone or water in the cavity will not leak due to vaporization. The rotating plate 241 and the floating plate 31 are connected by a rotating member. The rotating member includes a connecting plate 32 slidably connected to the inner wall of the fixed cylinder 24, and the bottom of the connecting plate 32 is in contact with the top of the floating plate 31. The top of the connecting plate 32 is fixedly connected with an extension column 33. An engaging column 331 is installed on the outer periphery of the extension column 33. The inner wall of the fixed cylinder 24 is fixedly connected with a fixed cylinder 24, and a spiral groove 341 in contact with the engaging column 331 is formed inside the mounting cylinder 34. The top of the extension column 33 is provided with a telescopic member. The telescopic member includes a multi-section telescopic plate 35 fixedly connected to the top of the extension column 33. A multi-section telescopic groove 351 is formed inside the multi-section telescopic plate 35. The multi-section telescopic plate 35 and the multi-section telescopic groove 351 are connected by a limiting block. The bottom of the rotating plate 241 is connected to the multi-section telescopic plate 35; When the heat exchange machine faces the situation of too high temperature, in order to improve the heat exchange efficiency of the heat exchange fluid, as the temperature rises, the liquid in the inner cavity of the mounting frame 11 will evaporate and vaporize under the action of high temperature. Under the push of the air pressure, the floating plate 31 rises accordingly, and the connecting plate 32 and the extension column 33 are driven to rise together. The engaging column 331 connected to the outer periphery of the extension column 33 moves along the spiral groove 341 during the rising process, thereby driving the extension column 33 and the connecting plate 32 to rotate. As the extension column 33 rotates, the multi-section telescopic plate 35 fixedly connected to its top moves in the multi-section telescopic groove 351, and under the constraint of the limiting block, the rotating plate 241 is driven to rotate in the rotating groove 244. The rotation of the rotating plate 241 further drives the baffle 242 to move, so as to dynamically adjust the distance between the baffle 242 and the closing plate 243, expand the contact area between the heat exchange fluid and the mounting frame 11, and enhance the heat exchange efficiency. The higher the temperature of the mounting frame 11, the greater the amount of liquid vaporization, and the corresponding increase in the adjustment of the distance between the baffle 242 and the closing plate 243; When the heat exchange machine stops working, the vaporized liquid will gradually lose heat and cool and condense back into a liquid state. At the same time, the disappearance of the air pressure causes the floating plate 31 to descend. This process will also push the liquid remaining on the inner wall of the cavity to slide down, effectively preventing liquid residue. As the floating plate 31 descends, the distance between the baffle 242 and the closing plate 243 will also be correspondingly reduced and restored to the initial state.

[0023] Such as Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 、 Figure 8As shown, a mixing assembly 40 is installed inside the baffle 242, and the mixing assembly 40 includes a mounting column 41 rotatably mounted on the inner wall of the liquid inlet 25, and a plurality of rotating plates 42 are connected to the outer periphery of the mounting column 41. The mixing assembly 40 also includes a plurality of slots 43 provided inside the mounting frame 11, and a positioning column 431 is fixedly connected between the inner walls of the slots 43, and a dial plate 432 is connected to the outer periphery of the positioning column 431 through a torsion spring 433, and the dial plate 432 is in contact with the baffle 242; In order to enhance the heat exchange effect of the heat exchange liquid inside the mounting frame 11, the following measures are taken: first, as the heat exchange liquid flows, it pushes the rotating plate 42 and the mounting column 41 to rotate on the inner wall of the liquid inlet 25. This dynamic process further stirs the heat exchanged liquid, ensuring that the temperature of the heat exchange liquid is more uniform, thereby improving the heat exchange efficiency; Secondly, when the temperature of the mounting frame 11 rises and drives the baffle plate 242 to rotate, the baffle plate 242 will press against the dial plate 432, causing it to rotate with the positioning column 431 as the center of the circle, and squeeze the torsion spring 433. Once the baffle plate 242 and the dial plate 432 are out of contact, the torsion spring 433 in the squeezed state will rebound, driving the dial plate 432 to reset. During this process, the dial plate 432 will swing the heat exchange liquid flowing through, further promoting the mixing of the heat exchange liquid, making the adsorption temperature of the heat exchange liquid more uniform. It is worth noting that as the distance between the baffle plate 242 and the closing plate 243 increases, the number of times the dial plate 432 moves the heat exchange liquid will increase accordingly, which further improves the mixing degree and temperature uniformity of the heat exchange liquid. In addition, as the heat exchange liquid flows, a portion of the liquid will flow through the gap between the slot 43 and the dial plate 432, and this portion of the liquid will collide with the normally flowing heat exchange liquid. This collision process also helps to improve the overall uniformity of the heat exchange liquid.

[0024] like Figure 1 , Figure 2 , Figure 9As shown in the figure, an expansion component 50 is installed inside the mounting bracket 11. The expansion component 50 includes a welding plate 51 fixedly connected inside the mounting bracket 11 and a support frame 52. An arc-shaped groove is formed inside the support frame 52. An arc-shaped rod 53 is slidably connected inside the support frame 52 through the arc-shaped groove. The centers of the support frame 52 and the arc-shaped rod 53 are the same as that of the fixed cylinder 24. Both ends of the arc-shaped rod 53 are respectively connected with a closing plate 243 and a connecting plate 54. A driving source is installed between the connecting plate 54 and the welding plate 51. The driving source includes a fixed frame 55 fixedly connected to one side of the welding plate 51. A positioning rod 551 is installed between the inner walls of the fixed frame 55. A rotating sleeve rod 552 is rotatably connected to the outer periphery of the positioning rod 551. A limiting rod 553 is fixedly connected between the inner walls of the connecting plate 54. A rotating sleeve rod 554 is rotatably connected to the outer periphery of the limiting rod 553. An electric push rod 555 is installed between the rotating sleeve rod 554 and the rotating sleeve rod 552. The fitting ends of the closing plate 243 with the fixed cylinder 24 and the rotating plate 241 are set as arc angles that fit the fixed cylinder 24 and the rotating plate 241. One end of the closing plate 243 that fits the inner wall of the frame body 10 is also set as an arc angle. When the closing plate 243 moves, there will be no leakage situation; When the temperature of the heat exchange machine is maintained at a constant state, but it is necessary to further increase the heat exchange efficiency, it can be achieved by starting the electric push rod 555. As the electric push rod 555 contracts, it will pull the connecting plate 54 connected to the limiting rod 553 inside the rotating sleeve rod 554 to move. This movement drives the arc-shaped rod 53 to slide along the arc-shaped groove on the support frame 52. Furthermore, the arc-shaped rod 53 will pull the closing plate 243 to move along the periphery of the fixed cylinder 24 and the rotating plate 241, thereby increasing the space between the closing plate 243 and the baffle 242. This adjustment increases the contact area between the heat exchange liquid and the mounting bracket 11, and thus improves the heat exchange efficiency of the heat exchange liquid for the mounting bracket 11.

[0025] Working principle: In order to conduct heat exchange, the mounting bracket 11 needs to be tightly installed at the heat-generating part of the machine. After the mounting bracket 11 effectively absorbs heat, the heat exchange fluid in the loading box 23 is driven by the water pump 21 and enters the inside of the mounting bracket 11 through the connecting pipe 22. During this process, the baffle 242 and the closing plate 243 construct a closed space, forcing the heat exchange fluid to enter through the liquid inlet 25 and circulate back to the water pump 21 along the flow channel 251, realizing efficient heat exchange and protecting the machine from overheating damage; When the temperature of the machine is too high, the liquid in the inner cavity of the mounting bracket 11 evaporates and vaporizes, pushing the floating plate 31 and the connecting component to rise and rotate, dynamically adjusting the distance between the baffle 242 and the closing plate 243, expanding the heat exchange area, and improving the heat exchange efficiency. The higher the temperature, the greater the vaporization amount, and the more significant the distance adjustment. When the machine stops working, the vaporized liquid cools and condenses, the floating plate 31 descends, and returns to the initial state, while clearing the residual liquid; In order to enhance the heat exchange effect, the following measures are taken: first, when the heat exchange fluid flows, the rotating plate 42 is pushed to rotate, stirring the liquid and making the temperature uniform; second, when the baffle 242 rotates, the paddle plate 432 is squeezed, and the torsion spring 433 is used to rebound and drive the paddle plate 432 to swing, thereby increasing the liquid mixing and temperature uniformity. When the spacing increases, the number of paddles increases, further improving the mixing and uniformity; third, part of the heat exchange fluid collides with the main fluid through the gap of the paddle plate 432, thereby improving the overall uniformity; When the heat exchange efficiency needs to be improved at a constant temperature, the electric push rod 555 is started to contract, pulling the connecting plate 54 and the arc rod 53 to move, increasing the distance between the closing plate 243 and the baffle 242, increasing the heat exchange area, and improving the heat exchange efficiency.

[0026] 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.
