Description

Technical Field

[0001] The invention relates to the technical field of ventilation and heat exchange, and in particular to a self-cleaning heat exchanger with high ventilation effect. Background Art

[0002] In the existing field of ventilation and heat exchange technology, heat exchangers, as an important equipment, are widely used in air conditioning, industrial refrigeration and ventilation systems. Their main function is to achieve temperature regulation through heat exchange of fluid media.

[0003] For example, a stainless steel shell and tube heat exchanger provided by publication number CN111692898B replaces the multi-stage straight pipe flow channel with a threaded pipe to increase or decrease the flow flow, thereby controlling the temperature, increasing the water flow stroke of the first inner flow channel within a specified range, and ensuring the water flow rate. It can quickly adjust the length of the water flow process according to the on-site environment or equipment requirements, thereby changing the temperature to meet equipment requirements.

[0004] If a screw stroke rod is used, while keeping the amount of injected fluid constant, the volume of the screw stroke rod occupies a part of the space in the pipeline, and the screw stroke rod increases the flow path of the fluid. The fluid will accumulate in the pipeline, which may easily lead to excessive local pressure, thereby affecting the stability and operational safety of the heat exchanger.

[0005] Publication No. CN114543352B provides a self-cleaning heat exchanger with high ventilation effect. After the airflow passes through the surface of the fin component, a vortex is generated due to the pressure change on the rear side of the fin component. On the one hand, the air pressure vortex can increase the air heat exchange residence time and effectively improve the heat exchange efficiency. On the other hand, the retained vortex can capture particles through the circulation on the surface of the dust collecting plate, thereby effectively reducing the generation of dust on the outer wall of the fin component through the stackable fin mechanism and the dust collecting plate, and effectively improving the maintenance resistance.

[0006] Traditional heat exchangers usually adopt a fixed structure. Their heat exchange area is limited by the design size and is difficult to dynamically adjust according to actual needs. The heat exchange path of the fluid is relatively single. When the fluid residence time is insufficient, the heat exchange efficiency will be greatly reduced, resulting in low energy utilization. Moreover, when the heat exchanger is in operation for a long time, its heat exchange surface is prone to reduce the heat conduction efficiency due to the accumulation of dust and impurities, which not only increases the frequency of maintenance and cleaning, but may also cause premature damage to the equipment or performance degradation. In addition, existing heat exchangers mostly use manual cleaning methods, which are inefficient and require the equipment to be suspended during the cleaning process, affecting normal use. Summary of the invention

The mounting cylinder is fixed at the center of the main pipeline. The double-headed gear rotates in the mounting cylinder, and the driving gear rod is slidably connected to both sides of the main pipeline.

[0013] As a further description of the above technical solution: a driving motor is installed on the mounting shell, and a driving rod rotatably connected to the mounting shell passes through the rectangular groove of the mounting shell, the driving rod passes through the double-headed gear and drives the double-headed gear to rotate, and the driving rod and the output end of the driving motor are driven by a belt.

[0014] As a further description of the above technical solution: annular fixing seats are provided on both sides of the inner cavity of the main pipe, and sealing rings are fixedly installed in the annular grooves of the annular fixing seats. Several input pipes and output pipes are respectively provided on both sides of the main pipe, and the input pipe away from the air outlet is connected to the spiral pipe through a pipe.

[0015] As a further description of the above technical solution: the unlocking structure includes a rectangular plate installed on both sides of the mounting plate, a moving rod slidingly passing through the rectangular plate, a rectangular head fixed on the moving rod, and inclined surfaces are provided on the upper and lower sides of the rectangular head. The moving rod sleeve is provided with a first return spring fixedly connected to the rectangular plate and the rectangular head.

[0016] As a further description of the above technical solution: the baffle structure includes a slide rail installed at the connection point between the main pipeline and the auxiliary pipeline, the slide rail is slidably connected with a sealing plate, the sealing plate is provided with a locking hole, and the upper and lower sides of the sealing plate and the upper and lower sides of the locking hole are equipped with inclined surfaces.

[0017] As a further description of the above technical solution: the locking structure includes a locking shell installed on the outer wall of the main pipe by bolts, a partition plate is installed in the locking shell, a locking rod slides through the partition plate, a locking head is fixed to the locking rod, one side of the locking head is provided with an inclined surface, the locking rod sleeve is provided with a second return spring fixedly connected to the partition plate and the locking head, and the locking head penetrates into the inner cavity of the main pipe.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] 1. It is driven by a motor and the gear transmission system drives the driving gear rod to move, thereby realizing the closing or expansion of the spiral stroke rod. When the spiral stroke rod enters the main pipeline, the DC pipeline is converted into a spiral pipeline, thereby extending the flow path of the fluid and increasing its residence time, greatly improving the contact efficiency between the fluid and the heat exchange surface, thereby improving the heat exchange effect of the main pipeline.

[0022] 2. When the spiral stroke rod pushes the baffle structure to open the through hole leading to the secondary pipe, the fluid flows into the secondary pipe, thereby significantly increasing the overall heat exchange area of ​​the heat exchange tube and further improving the heat exchange efficiency. After the spiral stroke rod is withdrawn, the baffle structure automatically resets to prevent the fluid from entering the secondary pipe, ensuring that the fluid path returns to the main pipe, realizing dynamic switching and optimization of the fluid flow path.

[0023] 3. The through hole for the fluid to enter the secondary pipeline from the main pipeline is designed at an adjacent position to the through hole of the input pipeline. When the spiral stroke rod is inserted into the main pipeline, its volume occupies part of the space, slowing down the flow rate of the fluid, causing part of the fluid to automatically flow to the secondary pipeline, avoiding the increase in local pressure caused by fluid accumulation. Through reasonable diversion design, the secondary pipeline is filled with fluid without increasing the fluid injection amount, effectively reducing the energy consumption of the system.

[0024] 4. The rotating rods on both sides of the main pipe penetrate the auxiliary pipe and are covered with heat transfer fins. The rotating motor drives the heat transfer fins to rotate. By rotating the angle of the fins, the airflow can be directed to both sides or concentrated to the center. When the heat transfer fins are parallel to the air inlet direction, the ventilation volume is the largest, and the air volume can be precisely controlled. When it rotates to the set angle, the lifter automatically drives the cleaner to move up and down to clean the dust on the fin surface. After cleaning, the dust is sucked into the dust collection box to ensure long-term stable heat exchange performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] See also Figure 1-Figure 15 The present invention provides a self-cleaning heat exchanger with high ventilation effect, including a mounting shell 10. The mounting shell 10 is a columnar structure. A rectangular groove is provided at the center of the mounting shell 10. A dust box 11 and a lifter 12 are installed on both sides of the rectangular groove. The lifter 12 is arranged on both sides of the dust box 11.

[0048] In the prior art, the dust box 11 is an important component in the heat exchanger, and its main function is to collect and process dust and debris generated during the heat exchange process. In the present invention, when the dust box 11 is working, dust and debris are sucked into the dust box 11 through the air inlet. A filtering device is provided in the dust box 11 for capturing particulate matter in the air, such as dust, hair, etc. After passing through the filter, the clean air continues to flow to the heat exchange part of the heat exchanger. The dust box 11 is equipped with a regular cleaning function. Through periodic cleaning, the dust box 11 can maintain a high dust collection efficiency and prevent dust and pollutants from clogging the equipment.

[0049] The lifting end of the lifter 12 is equipped with a cleaner 13. The operating mechanism of the lifter 12 relies on a mechanical structure (such as a motor and gears, etc.), so that the cleaner 13 installed thereon can move vertically in a rectangular groove, thereby automatically removing dust and ensuring that the heat exchanger maintains efficient operation.

[0050] On the inner wall of the rectangular groove, there are several circular air outlet holes 101, which can efficiently guide the airflow out of the heat exchanger. In the working state, the external air enters the rectangular groove and is discharged through the air outlet holes 101, ensuring the smooth flow of the airflow, thereby improving the heat exchange efficiency.

[0051] In the annular inner cavity of the mounting shell 10, a spiral tube 14 is provided, in which a fluid flows. The flow of the fluid heats the spiral tube 14, thereby heating the mounting shell 10. The fluid flows from one side of the spiral tube 14 close to the air outlet 101 to the other side away from the air outlet 101. The fluid is a key medium for achieving heat transfer in the heat exchanger. In the present invention, the fluid comes from an external cooling or heating system and is introduced into the spiral tube 14 through a specific fluid pipeline.

[0052] Furthermore, a plurality of mounting tubes 20 are installed on the upper and lower sides of the rectangular groove, and a pair of strip linear slide grooves are provided on the periphery of each mounting tube 20, in which a connecting ring 22 is slidably connected, and the connecting ring 22 is fixedly connected to the spiral stroke rod 21 inside the mounting tube 20. When the temperature and heat exchange area of ​​the heat exchanger need to be adjusted, the connecting ring 22 can drive the spiral stroke rod 21 to slide along the length direction of the mounting tube 20 to realize the expansion or contraction of the spiral stroke rod 21. The spiral stroke rod 21 is fixed with a mounting plate 23 with a fan-shaped hole, and an unlocking structure 24 is arranged on the mounting plate 23.

[0053] Furthermore, a heat exchange tube 30 is fixedly connected between the upper and lower mounting tubes 20 by bolts. The heat exchange tube 30 is composed of a main pipe 301 and a plurality of sub-pipes 302 of different sizes which are interconnected. The main pipe 301 is interconnected with the sub-pipe 302 and the upper and lower mounting tubes 20. The main pipe 301 is evenly divided into two sections and fixedly connected by bolts. After the bolts are removed, the components of the inner cavity of the main pipe 301 can be easily installed or replaced, thereby improving the convenience of installation and maintenance.

[0054] A mounting tube 31 is clamped and fixed at the center of the main pipe 301, and the mounting tube 31 passes through the main pipe 301. A double-headed gear 32 is assembled inside the mounting tube 31 by a rotating connection. Reciprocating driving gear rods 33 are respectively provided on both sides of the main pipe 301. The two ends of the double-headed gear 32 are respectively meshed with the two driving gear rods 33. The two driving gear rods 33 extend to the upper and lower connecting rings 22 respectively, and are fixedly connected to the connecting rings 22 by bolts. By rotating the double-headed gear 32, the two ends of the double-headed gear 32 can be used to drive the two driving gear rods 33 to move in opposite directions, thereby driving the spiral stroke rod 21 to expand or contract through the connecting ring 22.

[0055] When the heat exchange area needs to be increased, the driving gear rod 33 is moved by the motor, thereby driving the spiral stroke rods 21 on both sides to move closer to the main pipe 301 along the linear slide groove of the mounting tube 20. When the spiral stroke rod 21 enters the main pipe 301, the spiral stroke rod 21 can convert the direct current channel in the main pipe 301 into a spiral channel, thereby extending the flow path and residence time of the fluid, and further improving the heat exchange efficiency of the main pipe 301; when the spiral stroke rod 21 pushes the baffle structure 34 in the main pipe 301 to open, the fluid can flow from the main pipe 301 into the secondary pipe 302, and the heat exchange area is significantly increased and the heat exchange efficiency is improved through the secondary pipe 302. The size of the secondary pipe 302 is smaller than the main pipe 301.

[0056] Furthermore, a driving motor 15 is installed on the mounting shell 10, and a driving rod 151 rotatably connected to the mounting shell 10 passes through the rectangular groove of the mounting shell 10, the driving rod 151 passes through the double-headed gear 32 and drives the double-headed gear 32 to rotate, and the driving rod 151 and the output end of the driving motor 15 are driven by a belt. The driving motor 15 can drive the driving rod 151 to rotate, thereby driving the driving rod 151 to rotate, and then driving a plurality of double-headed gears 32 to rotate.

[0057] By driving the motor 15, the driving rod 151 and the double-headed gear 32, multiple double-headed gears 32 can be efficiently driven to rotate synchronously, avoiding unstable operation caused by transmission errors and ensuring the stability and reliability of the heat exchanger during operation.

[0058] Furthermore, an annular fixing seat 303 is provided on both sides of the inner cavity of the main pipeline 301, and a sealing ring 304 is fixedly installed in the annular groove of the annular fixing seat 303. The function of the sealing ring 304 is to prevent the fluid from entering the installation tube 20 from the main pipeline 301. The annular fixing seat 303 and the sealing ring 304 are set to be replaceable and have a long service life. After aging, they can be replaced according to usage requirements or actual conditions to ensure the sealing of the pipeline and prevent liquid from flowing out.

[0059] Furthermore, a plurality of input pipes 305 and output pipes 306 are respectively provided on both sides of the main pipe 301. The input pipes 305 and output pipes 306 of different main pipes 301 are interconnected through pipes, and the input pipe 305 away from the air outlet 101 is connected to the spiral pipe 14 through the pipe; during operation, the fluid first enters the spiral pipe 14, and then is transported to the end away from the air outlet 101 through the spiral pipe 14, and then enters the main pipe 301 away from the air outlet 101 through the pipe passing through the mounting shell 10. The fluid circulates between different main pipes 301 through the input pipes 305 and output pipes 306, and finally the fluid is output to the external cooling or heating system through the output pipe 306 close to the air outlet 101.

[0060] The through hole through which the fluid flows into the secondary pipe 302 through the main pipe 301, and the input pipe 305 and the output pipe 306 are designed in adjacent positions. When the spiral stroke rod 21 is inserted into the main pipe 301, its volume occupies a part of the space of the main pipe 301. The spiral stroke rod 21 not only increases the flow path of the fluid, but also effectively reduces the flow rate of the fluid in the main pipe 301. Therefore, the blocked fluid will automatically redirect to flow to the secondary pipe 302.

[0061] Specifically, the design optimizes the fluid distribution and improves the heat exchange performance by means of a reasonable pipeline structure design and a fluid guiding mechanism while keeping the amount of injected fluid unchanged. In the traditional heat exchanger design, if a spiral stroke rod 21 is used, the fluid will accumulate in the main pipeline 301, which may easily lead to excessive local pressure, thereby affecting the stability and operational safety of the heat exchanger. By diverting the fluid in the main pipeline 301 to the secondary pipeline 302, fluid accumulation is avoided and the pressure in the main pipeline 301 is effectively reduced. In addition, the spiral stroke rod 21 itself occupies part of the space of the main pipeline 301 and increases the flow path of the fluid, which slows down the flow rate of the fluid in the main pipeline 301 and causes the blocked fluid to automatically flow to the secondary pipeline 302. By means of a reasonable diversion design, the secondary pipeline 302 is filled with fluid while keeping the amount of injected fluid constant, thereby eliminating the need to increase the amount of fluid injected and reducing system energy consumption.

[0062] Furthermore, the inner wall of the main pipe 301 is provided with a plurality of baffle structures 34 , and when the spiral stroke rod 21 exits the main pipe 301 , these baffle structures 34 can automatically reset to close the through hole leading to the secondary pipe 302 , thereby limiting the fluid path within the main pipe 301 .

[0063] Furthermore, the unlocking structure 24 includes a rectangular plate 241 installed on both sides of the mounting plate 23, a slidable moving rod 242 is provided on the rectangular plate 241, a rectangular head 243 is fixedly connected to the moving rod 242, the upper and lower sides of the rectangular head 243 are provided with inclined surfaces, and a first return spring 244 is sleeved on the moving rod 242, the first return spring 244 is fixedly connected to the rectangular plate 241 and the rectangular head 243, and under the action of the first return spring 244, the rectangular head 243 can be against the inner wall of the main pipe 301.

[0064] Furthermore, the baffle structure 34 includes a slide rail 341 installed at the connection point between the main pipe 301 and the secondary pipe 302, and a sealing plate 342 is slidably connected to the slide rail 341. A locking hole 343 is provided on the sealing plate 342, and the upper and lower sides of the sealing plate 342 and the upper and lower sides of the inner wall of the locking hole 343 are provided with inclined surfaces. When the inclined surfaces on the upper and lower sides of the rectangular head 243 contact the inclined surfaces of the sealing plate 342, and the sealing plate 342 is restricted by the slide rail 341 and cannot move, the rectangular head 243 will move in the direction away from the inner wall of the main pipe 301.

[0065] After the spiral stroke rod 21 is separated from the main pipe 301, the sealing plates 342 at both ends are returned to the sealing state and fixed. This process can be achieved through existing technology. For example, a high magnetic material (such as a permanent magnet or a soft magnet) is installed on the sealing plate 342, and a metal plate or magnetic material is installed at the corresponding position in the main pipe 301. After the sealing plate 342 is returned to its position, the magnetic force generated by the magnetic material thereon fixes it firmly in the sealing position. The magnetic force is strong enough to resist fluid pressure and vibration, but will not hinder the normal sliding and unlocking operation of the sealing plate 342. Alternatively, the sealing plate 342 can also be fixed by the cooperation of the buckle and the fixing groove, or in the sealed state, a locking structure 40 is also installed at the corresponding position to lock the sealing plate 342 in the sealed state. The specific fixing method can be selected according to actual needs.

[0066] Furthermore, a plurality of locking structures 40 are installed on both sides of the outer circle of the main pipe 301 by bolts. The locking structure 40 includes a locking shell 41 installed on the outer wall of the main pipe 301 by bolts. A partition plate 42 is installed in the locking shell 41. A locking rod 43 slides through the partition plate 42. A locking head 44 is fixed to the locking rod 43. One side of the locking head 44 is provided with an inclined surface. The locking rod 43 is provided with a second return spring 45 fixedly connected to the partition plate 42 and the locking head 44. The locking head 44 penetrates into the inner cavity of the main pipe 301. The locking head 44 can fix the sealing plate 342 in the unsealed state.

[0067] refer to Fig.14 In the working state, the sealing plate 342 completely closes the through hole leading to the secondary pipe 302 in the initial position, so that the fluid can only flow in the main pipe 301. At this time, the spiral stroke rod 21 enters the main pipe 301, and the inclined surface of the rectangular head 243 on the mounting plate 23 contacts the inclined surface of one side of the sealing plate 342. Due to the action of the first return spring 244, the rectangular head 243 fits tightly against the inner wall of the main pipe 301 and remains stationary. The movement of the rectangular head 243 drives the sealing plate 342 to slide along the moving direction of the spiral stroke rod 21. During this process, the sealing plate 342 will contact the inclined surface of the locking head 44, prompting the locking head 44 to move toward the inside of the locking shell 41, and the locking head 44 will not hinder the sliding of the sealing plate 342 during this process.

[0068] When the sealing plate 342 fully opens the through hole leading to the secondary pipe 302, the sealing plate 342 cannot move further due to the restriction of the slide rail 341, and the locking head 44 will be inserted into the locking hole 343 to fix the sealing plate 342 in the current position. At this time, the spiral stroke rod 21 continues to move. Due to the inclination of the contact surface between the rectangular head 243 and the sealing plate 342, the rectangular head 243 slides in the direction away from the sealing plate 342, causing the rectangular head 243 to press against the sealing plate 342, and the spiral stroke rod 21 drives the rectangular head 243 to move in the sealing plate The surface of rectangular head 243 slides and moves into the locking hole 343. At this time, the rectangular head 243 pushes the locking head 44 to move into the locking shell 41, thereby releasing the lock on the sealing plate 342. However, since the inclined surface of the rectangular head 243 is against the inclined surface of the locking hole 343, the sealing plate 342 remains stationary. When the rectangular head 243 is about to leave the locking hole 343, the locking head 44 is reinserted into the locking hole 343, so that after the rectangular head 243 leaves the sealing plate 342, the locking head 44 can lock the sealing plate 342 again.

[0069] As the rectangular head 243 moves, it will release the sealing state of different sealing plates 342 along the way in turn and fix them at a position away from the through holes of the auxiliary pipe 302. When the upper and lower spiral stroke rods 21 move synchronously, the through holes at both ends of different auxiliary pipes 302 will be opened synchronously. The synchronization mechanism improves the efficiency of operation and the switching accuracy of the fluid path, ensures the uniform distribution of the fluid in the auxiliary pipe 302, and optimizes the heat exchange effect.

[0070] When the spiral stroke rod 21 is separated from the main pipe 301, the inclined surface of the rectangular head 243 contacts the inclined surface of the other end of the sealing plate 342, causing the rectangular head 243 to slide away from the sealing plate 342, thereby making the rectangular head 243 abut against the sealing plate 342. When moving into the locking hole 343, the rectangular head 243 will push the locking head 44 to move into the locking shell 41, thereby releasing the lock on the sealing plate 342. At this time, since the moving direction of the sealing plate 342 is no longer restricted by the slide rail 341, the locking head 44 no longer locks the sealing plate 342, so that the rectangular head 243 can drive the sealing plate 342 to return to the sealing position.

[0071] During the movement of the spiral stroke rod 21, the through holes at both ends of different auxiliary pipes 302 will be opened and closed synchronously. Once closed, there will be fluid residue inside the auxiliary pipe 302. For this reason, a discharge pipe is added at an appropriate position of the auxiliary pipe 302. The discharge pipe is directly connected to the auxiliary pipe 302. Its function is to guide the fluid to be discharged when the auxiliary pipe 302 is closed. The discharge pipe can be equipped with a one-way valve so that when the sealing plate 342 of the auxiliary pipe 302 is closed, the one-way valve automatically opens to allow the remaining fluid to be discharged through the discharge pipe. The outlet of the discharge pipe can be directly connected to the reflux pipe or other waste liquid collection system to ensure that the fluid will not be retained; in addition, specific fluids (such as coolants or other media with excellent thermal conductivity) can also be selected. Even if they remain in the auxiliary pipe 302, they will not significantly affect the heat exchange efficiency, thereby ensuring the long-term stability of the heat exchanger under different working conditions.

[0072] Furthermore, rotating rods 51 penetrating the secondary pipe 302 and sleeved with heat transfer fins 50 are provided on both sides of the main pipe 301. The rotating rods 51 on the side close to the air outlet 101 are fixedly connected to the rotating end of the rotating motor 52 embedded in the mounting shell 10, and a plurality of rotating rods 51 are sleeved with transmission belts.

[0073] During operation, the rotating motor 52 drives the heat transfer fins 50 to rotate, and uses the guiding effect of the fins to adjust the direction of the wind. When the heat transfer fins 50 rotate to be parallel to the air inlet direction, the airflow is discharged along the heat transfer fins 50, and the ventilation volume reaches a maximum. By controlling the rotation angle of the heat transfer fins 50, the system can effectively adjust the ventilation volume of the heat exchanger. At a specific angle, the air volume is the largest, and the optimal heat exchange effect can be achieved. Using this dynamic adjustment function, the heat exchanger can more accurately adjust the ventilation volume according to the external environment or work requirements, thereby maximizing the heat exchange efficiency.

[0074] And after rotating to a specific angle, the lifter 12 can drive the cleaner 13 to move up and down, and use the cleaner 13 to clean the heat transfer fins 50, and then the dust box 11 absorbs the cleaned dust. The automatic cleaning function greatly reduces the frequency and labor cost of manual cleaning, ensuring that the equipment can maintain efficient operation for a long time, reducing the reduction in heat exchange efficiency and equipment failure caused by dust accumulation.

[0075] Furthermore, a cross bar 16 is provided on the outer sleeve of the mounting tube 20, and the cross bar 16 is fixed with a support rod 17 by bolts. The support rod 17 is installed in a rectangular groove, and the cross bar 16 and the support rod 17 are fixed by bolts. The interval between different cross bars 16 can be changed very conveniently, thereby changing the interval between the heat exchange tubes 30. The user can quickly adjust the arrangement of the heat exchange tubes 30 according to the actual working conditions (such as installation space or airflow requirements), which is convenient for maintenance and optimization, and meets the diverse requirements of different equipment and working conditions for the heat exchanger structure.

[0076] 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.
