Description

Technical Field

[0001] This utility model relates to the field of radiator technology, specifically to an aluminum plate-fin radiator with flow rate control function. Background Technology

[0002] Plate-fin heat exchangers typically consist of baffles, fins, seals, and guide vanes. Fins, guide vanes, and seals are placed between adjacent baffles to form a sandwich, called a channel. These sandwiches are stacked according to different fluid flow patterns and brazed into a whole to form a plate bundle. The plate bundle is the core of the plate-fin heat exchanger. Plate-fin heat exchangers are widely used in industries such as petroleum, chemical, and natural gas processing. Plate-fin radiators are usually composed of a series of parallel metal plates and thin fins.

[0003] In existing technologies, numerous tiny channels are formed between the metal plate and the fins for fluid flow. Heat is transferred through convection and conduction between the surface of the plate-fin structure and the fluid within the channels. During the use of the radiator, the fluid flows within the fluid channels of the radiator, exchanging heat with the air in conjunction with the fins. The fluid flow rate affects the radiator's heat dissipation effect. Currently, the fluid velocity in plate-fin radiators used in various fields is fixed, making it impossible to control the fluid flow rate. If the fluid flows too fast, it will reduce heat exchange, thereby reducing the radiator's heat dissipation effect. Therefore, an aluminum plate-fin radiator with flow rate control function is proposed to solve the above-mentioned technical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an aluminum plate-fin radiator with flow rate control function. It has the advantage of slowing down the flow rate of fluid passing through the plate-fin radiator, thus solving the problem that excessively fast fluid flow reduces heat exchange and consequently reduces the radiator's heat dissipation effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an aluminum plate-fin radiator with flow rate control function, comprising a radiator body, the radiator body being composed of an inlet chamber, an outlet chamber and a plurality of finned tubes, an inlet pipe being provided on the inlet chamber, and a control mechanism capable of slowing down the fluid velocity being provided on the inlet pipe. The control mechanism includes a set of positioning plates on the inlet pipe, a flow-slowing plate rotatably arranged between opposite sides of the positioning plates, a plurality of pull rods on the flow-slowing plate, and a driving part connected to the pull rods on the inlet pipe, the driving part being used to drive the flow-slowing plate to perform circular motion.

[0006] Furthermore, the drive unit includes an adjusting screw disposed on the inlet pipe and extending through and into the inlet pipe at the other end, a drive component connected to the adjusting screw, and a connecting plate rotatably connected to the adjusting screw via a bearing.

[0007] Furthermore, the end of the pull rod away from the connecting plate is fixed to the flow-slowing plate, and the front and rear sides of the flow-slowing plate are in contact with the inner wall of the liquid inlet pipe.

[0008] Furthermore, a rotating rod is rotatably connected between the opposite sides of the positioning plates on the front and rear sides via a bearing, and the flow-damping plate is fixed to the rotating rod.

[0009] Furthermore, the inlet pipe is provided with a liquid blocking chamber, the connecting plate is located inside the liquid blocking chamber, the liquid blocking chamber is provided with a sealing sleeve, and the sealing sleeve has a through hole for the pull rod to pass through, the through hole and the pull rod are clearance fit.

[0010] Furthermore, two sliders are symmetrically arranged on the connecting plate, and two sliding grooves are symmetrically arranged on the liquid-blocking chamber, with the sliders and sliding grooves slidably connected.

[0011] Furthermore, a flow baffle is provided on the finned tube to reduce the fluid flow rate.

[0012] Furthermore, the number of the flow baffles is not less than two, and the flow baffles are arranged alternately on the finned tube.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects: This aluminum plate-fin radiator with flow rate control function drives the flow-regulating plate to move in a circular motion through the drive unit. The angle of the flow-regulating plate relative to the direction of fluid flow can be precisely adjusted. When enhanced heat dissipation is required, the tilt angle of the flow-regulating plate can be increased to increase flow resistance, effectively reduce fluid flow rate, and extend heat exchange time. When a larger flow rate is required, the tilt angle can be decreased to reduce flow resistance. This solves the core problem of traditional radiators having a fixed and unadjustable flow rate that cannot adapt to different working conditions.

[0014] This aluminum plate-fin radiator with flow rate control not only has an adjustable-angle flow damper at the inlet, but also has multiple staggered flow baffles on the internal finned tubes. This dual design further hinders fluid flow, reduces flow rate, and ensures more complete heat exchange between the fluid and the heat dissipation medium. Attached Figure Description

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] Please see Figure 1-2 The aluminum plate-fin radiator with flow rate control function in this embodiment has the advantage of slowing down the flow rate of fluid flowing through the plate-fin radiator, thus enabling the plate-fin radiator to have a slow flow function.

[0019] An aluminum plate-fin radiator with flow rate control function in this embodiment includes a radiator body 1. The radiator body 1 is composed of an inlet chamber 2, an outlet chamber 3 and several finned tubes 4. An inlet pipe is provided on the inlet chamber 2, and a control mechanism 5 that can slow down the fluid speed is provided on the inlet pipe. The control mechanism 5 includes a set of positioning plates 501 disposed on the liquid inlet pipe. A flow-slowing plate 502 is rotatably disposed between opposite sides of the positioning plates 501. Several pull rods 506 are disposed on the flow-slowing plate 502. A drive unit connected to the pull rods 506 is disposed on the liquid inlet pipe, and the drive unit is used to drive the flow-slowing plate 502 to perform circular motion.

[0020] It should be noted that the finned tube 4 is provided with multiple heat dissipation fins for the fluid to exchange heat with the outside world, and the liquid outlet chamber 3 is provided with a liquid outlet pipe, which is the channel for the fluid that has completed the heat exchange to leave the aluminum plate fin radiator. The radiator body 1 in this application is a common device in the prior art. At the same time, the working principle and usage method of the radiator body 1 are well known to those skilled in the art of radiator technology, and will not be described in detail in this application.

[0021] In application, coolant enters the inlet chamber 2 through the inlet pipe. In the default state, the flow depressor 502 is at a certain angle to the fluid flow direction, and the flow channel is relatively unobstructed. When the system needs to reduce the fluid flow rate to enhance the heat dissipation effect, the drive unit is activated, driving the pull rod 506 to move downward. At this time, the flow depressor 502 rotates counterclockwise, and the angle between it and the fluid flow direction increases. After the angle increases, the shielding area of ​​the flow depressor 502 on the fluid channel increases, the effective flow cross-sectional area decreases, and the resistance to fluid flow increases significantly, thereby forcing the fluid velocity flowing through this area to decrease. The fluid with reduced velocity then enters the finned tube 4 area. Due to the slower flow velocity, the fluid stays in the finned tube 4 for a longer time, making the heat exchange between it and the fins and the outside cold air more sufficient and thorough, thereby greatly improving the heat dissipation efficiency of the entire radiator. Conversely, when an increase in flow rate is required, the drive unit reverses its action, the pull rod 506 moves back, the angle of the flow depressor 502 decreases, the flow channel becomes unobstructed, the flow resistance decreases, and the fluid velocity is restored or increased accordingly. Example

[0022] The basic content is the same as in Example 1, except that: Please see Figure 1-3 and Figure 5 In order to reduce the speed of the fluid flowing through the plate-fin radiator and make the heat exchange more efficient, the drive unit in this embodiment includes an adjusting screw 503 disposed on the liquid inlet pipe and extending through and into the liquid inlet pipe at the other end, a drive member 504 connected to the adjusting screw 503, and a connecting plate 505 rotatably connected to the adjusting screw 503 via a bearing.

[0023] The end of the pull rod 506 away from the connecting plate 505 is fitted onto the flow buffer 502, and the front and rear sides of the flow buffer 502 are in contact with the inner wall of the inlet pipe.

[0024] It should be noted that the driving component 504 includes a device or structure such as a DC motor, AC motor or servo motor that can rotate the adjusting screw 503. Preferably, the driving component 504 is a servo motor in this application, which makes it easier to adjust the angle between the flow plate 502 and the positioning plate 501. The drive unit 504 is connected to the control unit. The control unit controls the output shaft of the drive unit 504 to rotate at a constant speed, which ultimately drives the adjusting screw 503 to rotate. The control unit and its working principle are well known to those skilled in the art and will not be described in this embodiment.

[0025] A liquid blocking chamber is provided on the liquid inlet pipe, and the connecting plate 505 is located inside the liquid blocking chamber. A sealing sleeve is provided on the liquid blocking chamber, and a through hole is formed on the sealing sleeve for the pull rod 506 to pass through. The through hole and the pull rod 506 are clearance-fitted, and the sealing sleeve plays the role of improving the sealing performance at the connection between the pull rod 506 and the liquid blocking chamber.

[0026] Two sliders are symmetrically arranged on the connecting plate 505, and two sliding grooves are symmetrically arranged on the liquid blocking chamber. The sliders and the sliding grooves are slidably connected.

[0027] It is understandable that when the connecting plate 505 moves, it causes the slider to slide in the groove, which limits the movement of the connecting plate 505, allowing it to move only up and down.

[0028] In application, when enhanced heat dissipation is required, the drive unit 504 receives a command and starts rotating. Since the drive unit 504 is connected to the adjusting screw 503, it drives the adjusting screw 503 to rotate as well. The rotational motion of the adjusting screw 503, through the bearing connection with the connecting plate 505, is converted into precise linear motion of the connecting plate 505 along the axis of the adjusting screw 503, i.e., moving the connecting plate 505 downwards. The symmetrically arranged sliders on the connecting plate 505 slide in cooperation with the grooves on the liquid-blocking chamber. This design ensures that the connecting plate 505 can only perform stable up-and-down linear motion, preventing rotation or deviation, and guaranteeing the accuracy and reliability of the motion. When the connecting plate 505 moves downwards, it drives the pull rod 506 fixed on it to move downwards synchronously. The downward pull of the pull rod 506 applies a pulling force to the flow-retarding plate 502. This pulling force forces the flow-retarding plate 502 to rotate around the rotating rod, thereby increasing the angle between it and the fluid flow direction. As the angle increases, the effective flow cross-sectional area of ​​the fluid channel in the inlet pipe decreases, which significantly increases the resistance to fluid flow, thereby forcing the fluid velocity entering the radiator to decrease. Example

[0029] The basic content is the same as in Example 1, except that: A baffle plate 507 is provided on the finned tube 4 to reduce the flow rate of the fluid. When the fluid flows through the finned tube 4, it is obstructed by the baffle plate 507 arranged in a staggered manner inside the finned tube 4, which further reduces the flow rate of the fluid and makes the fluid stay in the aluminum plate-fin radiator for a longer time, so that the heat exchange is more complete.

[0030] There are no fewer than two baffles 507, and the baffles 507 are arranged alternately on the finned tube 4.

[0031] In application, the fluid with initially reduced flow rate enters the finned tube 4. As the fluid flows in the finned tube 4, it is further obstructed by the staggered baffles 507 inside the tube, which further reduces the flow rate and prolongs the residence time of the fluid in the radiator. This allows the fluid to have more time to exchange heat with the fins and the outside cold air, thereby maximizing the heat dissipation efficiency.

[0032] In summary, the working principle of this aluminum plate-fin radiator with flow rate control function is as follows: When enhanced heat dissipation is required, the drive unit 504 receives a command and starts rotating. Since the drive unit 504 is connected to the adjusting screw 503, it drives the adjusting screw 503 to rotate as well. The rotational motion of the adjusting screw 503, through the bearing connection with the connecting plate 505, is converted into precise linear motion of the connecting plate 505 along the axis of the adjusting screw 503, i.e., moving the connecting plate 505 downwards. The symmetrically arranged sliders on the connecting plate 505 slide in conjunction with the grooves on the liquid-blocking chamber. This design ensures that the connecting plate 505 can only perform stable up-and-down linear motion, preventing rotation or deviation, and guaranteeing the accuracy and reliability of the motion. When the connecting plate 505 moves downwards, it drives the pull rod 506 fixed to it to move downwards synchronously. The downward pull of the pull rod 506 applies a pulling force to the flow-retarding plate 502. This pulling force forces the flow-retarding plate 502 to rotate around the rotating rod, thereby increasing the angle between it and the fluid flow direction. As the angle increases, the effective flow cross-sectional area of ​​the fluid channel in the inlet pipe decreases, which significantly increases the resistance to fluid flow, thereby forcing the fluid velocity entering the radiator to decrease.

[0033] After the initial flow rate is reduced, the fluid enters the finned tube 4. As the fluid flows in the finned tube 4, it is further obstructed by the staggered baffles 507 inside the tube, which further reduces the flow rate and prolongs the residence time of the fluid in the radiator. This allows the fluid to have more time to exchange heat with the fins and the outside cold air, thereby maximizing the heat dissipation efficiency.

[0034] Conversely, when an increase in flow rate is required, the drive unit reverses its action, the pull rod 506 moves back, the angle of the flow depressor 502 decreases, the flow channel becomes unobstructed, the flow resistance decreases, and the fluid velocity is restored or increased accordingly.
