Description

Technical Field

[0002] A heat exchanger is a device used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements. It is an industrial application of convective heat transfer and heat conduction. During the use of air conditioners, a heat exchanger is required to achieve cooling and heating effects.

[0003] The following problems exist in the existing technology and have not been well solved: 1. Since frost and condensed water are generated at the condensate delivery position during the use of the heat exchanger, the existing technology shakes off the condensed water and frost on the surface of the condenser by shaking. However, since dust will adhere to the surface of the heat exchanger during use, when the condensed water combines with the dust, it will agglomerate and adhere to the surface of the heat exchanger. It is difficult to effectively shake off the adhered and agglomerated dust and frost by shaking alone, which affects the heat exchange efficiency. Summary of the Invention

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] See also Figures 1 to 11 The present invention provides a technical solution: a condensate discharge type heat exchanger, comprising: The exchanger housing 1 has a condensate delivery sleeve 2 fixedly connected to the middle of the exchanger housing 1, and fins 3 that cooperate with the condensate delivery sleeve 2 are movably mounted on both the front and rear sides of the exchanger housing 1. It should be noted that a support rod is fixedly connected between the side wall of the condensate delivery sleeve 2 and the inner wall of the exchanger housing 1, so that the condensate delivery sleeve 2 is stably mounted inside the exchanger housing 1, and there are six condensate delivery sleeves 2, which are vertically equidistantly distributed inside the exchanger housing 1. The six condensate delivery sleeves 2 are connected by infusion elbows. An infusion head is fixedly connected to the right side of the top condensate delivery sleeve 2, and a drainage head is fixedly connected to the right side of the bottom condensate delivery sleeve 2. The infusion elbow, infusion head, and drainage head are prior art and will not be described in detail here.

[0019] Also includes: The condensate cleaning component 4 is arranged between the fin 3 and the condensate delivery sleeve 2. The transmission component 5 is movably connected between the surface of the fin 3 and the inner wall of the exchanger shell 1. The condensate cleaning component 4 is driven by the transmission component 5 to clean the frosted condensate and agglomerated dust on the surface of the condensate delivery sleeve 2.

[0020] In this embodiment, Figures 1 to 11As shown, the condensate cleaning assembly 4 includes a steel strand 401, which is overlapped on the surface of the condensate delivery sleeve 2. The front end of the steel strand 401 is fixedly connected to a retaining ring 402, and the outer part of the retaining ring 402 is movably connected to a force storage sleeve 403. A force storage spring 404 is movably connected between the inner wall of the force storage sleeve 403 and the side wall of the retaining ring 402. The front end of the force storage sleeve 403 and the rear end of the steel strand 401 are eccentrically mounted with a toothed disc 405, and the toothed disc 405 is rotatably connected to the surface of the corresponding fin 3. It should be noted that when the toothed disc 405 rotates, the steel strand 401 and the force storage sleeve 403, which are eccentrically mounted with the toothed disc 405, will rotate in a circular trajectory, so that the steel strand 401 can scrape the surface of the condensate delivery sleeve 2 during rotation.

[0021] A rack 406, meshing with a toothed disc 405, is fixedly connected between the two sides of the inner wall of the exchanger housing 1. A protrusion 407, mating with the steel strand 401, is fixedly connected to the center of the surface of the condensate transfer sleeve 2. It should be noted that when the fins 3, along with the toothed discs 405 and the steel strand 401, translate left and right in sync, the racks 406 mesh with the corresponding toothed discs 405, causing them to rotate along the sidewalls of the fins 3.

[0022] In this embodiment, Figures 1 to 11 As shown, the steel strand 401 is arranged between two front and rear fins 3, and the steel strand 401 between the two fins 3 is in a stretched state. It should be noted that the stretched steel strand 401 can produce a cutting effect on the frost on the surface of the condensate delivery sleeve 2 during the rotation process.

[0023] The condensate conveying sleeve 2 is tilted inside the exchanger housing 1, with the steel strands 401 located on the top and bottom surfaces of the sleeve 2. It should be noted that the tilted condensate conveying sleeve 2 facilitates the removal of condensate scraped off by the steel strands 401, along with frost and dust from the trapped particles, along the inclined surface of the sleeve 2.

[0024] In this embodiment, Figures 1 to 11 As shown, the transmission assembly 5 includes a screw rod 501, which is provided as two screw rods 501. The two screw rods 501 are symmetrically connected to the left side of the exchanger housing 1. A slide rod 502 is symmetrically fixedly connected to the right side of the exchanger housing 1. A slider 503 is slidably connected to the surface of the slider 502. A screw block 504 is threadedly connected to the surface of the screw rod 501. A transmission plate 505 is movably connected between the screw block 504 and the slider 503 on the same horizontal line. A Y-shaped toggle block 506 is fixedly connected to the surface of the transmission plate 505. The Y-shaped toggle block 506 is arranged between two adjacent fins 3. It should be noted that the screw rod 501 is configured as a reciprocating screw rod 501 type. When the screw rod 501 rotates, under the action of the screw block 504, the transmission plate 505 and the slider 503 reciprocate up and down along the trajectory of the slider 502.

[0025] Both ends of the transmission plate 505 are fixedly connected with pressure rods 507 , and the surface of the exchanger housing 1 is fixedly connected with trapezoidal pressure blocks 508 that match the pressure rods 507 .

[0026] Connecting rods 509 are fixedly connected between the upper ends of the fins 3 on the same horizontal line. Connecting rods 509 are movably connected between the two sides of the inner wall of the exchanger housing 1. It should be noted that balls are fixedly connected to the bottoms of the fins 3. The bottoms of the balls overlap the surface of the exchanger housing 1 to provide frictional resistance during the translation of the fins 3.

[0027] In this embodiment, Figures 1 to 11 As shown, the sidewalls of the transmission plate 505 are symmetrically formed with recessed grooves. Screw blocks 504 and sliders 503 are slidably connected within the two recessed grooves, respectively. Compression springs are fixedly connected to both sides of the inner walls of the recessed grooves. It should be noted that guide rods are fixedly connected to the interiors of the recessed grooves, and the screw blocks 504 and sliders 503 are slidably connected to the surfaces of the corresponding guide rods. The screw blocks 504 and sliders 503 are disposed between two compression springs on the inner walls of the corresponding recessed grooves.

[0028] In this embodiment, Figures 1 to 11 As shown, the distance between the left and right sides of the trapezoidal pressing block 508 is the same as the distance between two adjacent fins 3. It should be noted that when the pressing rod 507 on the transmission plate 505 contacts the inclined surface of the trapezoidal pressing block 508, the pressing rod 507 is pressed and causes the transmission plate 505 to move horizontally, causing the transmission plate 505 to move a distance that is the same as the distance between the two fins 3. During this process, the transmission plate 505 moves synchronously with the fins 3 via the Y-shaped toggle block 506.

[0029] The trapezoidal pressure blocks 508 on either side of the exchanger housing 1 are arranged in a vertically staggered arrangement. It should be noted that this vertically staggered arrangement allows the pressure rods 507 on either side of the transmission plate 505 to contact the trapezoidal pressure blocks 508 on either side of the exchanger housing 1 in a staggered manner when the transmission plate 505 moves downward, allowing the transmission plate 505 to reciprocate left and right between the screw block 504 and the slider 503 during the downward movement. At this time, the fins 3 can carry the steel strands 401 with them in a horizontally reciprocating movement.

[0030] In this embodiment, Figures 1 to 11 As shown, both ends of the connecting rod 509 are fixedly sleeved with limit rings. Sockets that mate with the limit rings are symmetrically provided on the upper inner wall of the exchanger housing 1. The connecting rod 509 slides between the two sockets via the limit rings. A return spring is movably connected between the side walls of the limit rings and the inner walls of the corresponding sockets. It should be noted that the connection between the connecting rod and the sockets enhances the stability of the fins during movement, and the return spring further enhances the return of the fins and transmission plate.

[0031] In this embodiment, Figures 1 to 11 As shown, a drive motor is fixedly connected to the left side of the top of the exchanger housing 1. Synchronous pulleys are fixedly connected to the rotating end of the drive motor and the tops of the two screw rods 501. A timing belt is movably connected between the three synchronous pulleys. It should be noted that a sewage pipe is installed on the left side of the lower portion of the exchanger housing 1 to facilitate the discharge of sewage generated after cleaning.

[0032] A sensor is fixedly attached to the left side of the inner wall of the exchanger housing 1. One side of the sensor overlaps the top surface of the adjacent condensate delivery sleeve 2. The sensor is electrically connected to the drive motor. It should be noted that when the sensor detects condensation or frost on the surface of the condensate delivery sleeve 2, the drive motor electrically connected to the sensor begins operating. The combination of the sensor and the drive motor is conventional and will not be described in detail here.

[0033] The use method and advantages of the present invention: The working process of the condensate discharge type heat exchanger is as follows: like Figures 1 to 11 As shown, when in use, when condensation water or frost is generated on the surface of the condensate conveying sleeve 2, the driving motor electrically connected to the sensor drives the two screw rods 501 to rotate synchronously, so that the screw block 504 on the screw rod 501 drives the transmission plate 505 to slide up and down on the surface of the corresponding slide rod 502. At this time, the transmission plate 505 drives the pressure rod 507 and the Y-shaped toggle block 506 to move vertically. When the pressure rod 507 moves to the position of the trapezoidal pressure block 508 on the side wall of the exchanger housing 1, the pressure rod 507 is pressed and drives the transmission plate 505 and the Y-shaped toggle block 506 to move horizontally. Since the trapezoidal pressure blocks 508 on both sides of the transmission plate 505 are arranged in a staggered manner, the transmission plate 505 can move back and forth during the downward movement, and then the Y-shaped toggle block 506 drives the overlapping fins 3 to move horizontally synchronously. In the process of the Y-shaped toggle block 506 moving down along the surface of the fin 3, the surface of the fin 3 can be cleaned. When the front and rear fins 3 of the exchanger housing 1 are synchronously moving back and forth, the steel strand 401 between the two opposite front and rear fins 3 is also translated along with the fin 3. One end of the steel strand 401 and one end of the force storage sleeve 403 are connected to the surface of the corresponding fin 3 through the eccentrically mounted toothed disc 405. When the fin 3 moves synchronously with the toothed disc 405, the toothed disc 405 is meshed with the rack 406 on the inner wall of the exchanger housing 1, so that the toothed disc 405 with the eccentrically mounted steel strand 401 and the force storage sleeve is rotated. 403 rotates synchronously on the surface of the condensate delivery sleeve 2 in a circular trajectory, and the toothed disc 405 that translates with the fin 3 will move synchronously with the steel strand 401 in a circular rotating state. When the steel strand 401 rotates to the surface of the condensate delivery sleeve 2, it will scrape off the condensate and at the same time have a cutting effect on frost and agglomerated dust. When the steel strand 401 cuts into the frost, the rotation of the steel strand 401 will produce a plucking effect on the frost, thereby effectively cleaning the frost or agglomerated dust. When the steel strand 401 rotates to the position of the protrusion 407 on the surface of the condensate delivery sleeve 2, the steel strand 401 is blocked and will slide with the retaining ring 402 inside the force storage sleeve 403, causing the force storage spring 404 to compress and store force. At this time, the steel strand 401 bends. After the steel strand 401 passes the position of the protrusion 407, the force storage spring 404 elastically recovers and straightens the steel strand 401 through the retaining ring 402. The force generated during the straightening process of the steel strand 401 acts on the surface of frost or agglomerated dust, which further improves the cutting and cleaning effect.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
