Description

Technical Field

[0001] The utility model relates to the technical field of air coolers, in particular to an energy-saving fin-type water turbine generator air cooler. Background Art

[0002] A hydroelectric generator, also known as a waterwheel generator, is a generator set that uses the rotation of a turbine to drive the rotation of the generator rotor to generate electricity. When in use, a hydroelectric generator is equipped with a special air cooler to cool the fluid. An air cooler is a heat exchanger that uses air to cool hot fluid. The hot fluid in the tube exchanges heat with the air outside the tube through the tube wall and fins. The air used is usually supplied by a ventilator.

[0003] Common air coolers are generally composed of tube bundles, fans and frames. The fans drive the air to flow to exchange heat and cool the hot fluid in the tubes. However, under the action of the fans, the air flow will flow rapidly toward the fans. The temperature of the air flow first entering the air cooler is relatively low. As the air comes into contact with the hot fluid pipes, the temperature of the air flow will gradually increase with contact with the pipes, making it difficult for the hot fluid pipes inside the air cooler to be evenly cooled by the air flow. As a result, the cooling efficiency of the air cooler still has room for improvement. Utility Model Content

[0004] The purpose of the utility model is to provide an energy-saving fin-type hydro-generator air cooler to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an energy-saving fin-type hydro-generator air cooler, comprising a base, a side support plate installed at the left and right edge positions of the upper end of the base, a plurality of fin-type thermal fluid pipes installed between the two side support plates, a connecting plate installed between the two fin-type thermal fluid pipes on the same horizontal line, a plurality of ventilation openings with a wider bottom and a narrower top are opened inside the connecting plate, a top plate is installed at the upper ends of the two side support plates, and a plurality of fans are installed at the upper end of the top plate.

[0006] Preferably, an air compression structure is installed between the two side support plates at a position outside the fin-type hot fluid pipeline.

[0007] Preferably, the air compression structure includes an inclined plate and a fixed plate, a fixed plate is fixedly installed at both the front and rear ends of the side support plate, and a plurality of downwardly inclined inclined plates are installed between the two fixed plates.

[0008] Preferably, the finned hot fluid pipe comprises a pipe body and metal fins, and a plurality of metal fins are evenly distributed on the surface of the pipe body.

[0009] Preferably, a connecting plate is installed on the outside of the side support plate, and multiple fin-type thermal fluid pipes pass through the side support plate and are connected to the connecting plate. A pipe inlet communicating with the fin-type thermal fluid pipe is opened at the lower end of one of the connecting plates, and a pipe outlet communicating with the fin-type thermal fluid pipe is opened at the lower end of another connecting plate.

[0010] Preferably, the plurality of fin-type thermal fluid pipes are distributed in a V-shape, and the widths of the plurality of connecting plates decrease sequentially from top to bottom.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. This energy-saving fin-type hydro-generator air cooler, under the action of multiple fans, allows external air to enter the two side support plates through the air compression structures on both sides. The airflow compressed once will first contact a fin-type thermal fluid pipe and then be blocked by the connecting plate. Part of the airflow will move upward through the vent and will be compressed twice inside the vent. Part of the airflow that has not passed through the vent will continue to move along the connecting plate and then contact another fin-type thermal fluid pipe on the same horizontal line. After contact, it will continue to move upward. The airflow that has been compressed twice will repeat the screening operation, part of the airflow will continue to be compressed, and part of the airflow will continue to move and contact other fin-type thermal fluid pipes, so that the airflow entering the device will be compressed and cooled more frequently as the height increases, and will contact the fin-type thermal fluid pipes, so the heat exchange efficiency will be higher.

[0013] 2. In this energy-saving fin-type hydro-generator air cooler, the hot fluid enters the interior of the connecting plate through the pipe inlet and enters the interior of the fin-type hot fluid pipe on the bottom layer, then gradually rises, and finally enters the interior of another connecting plate from the top layer of the pipe, and is then discharged from the pipe outlet. The hot fluid passes through all the fin-type hot fluid pipes from bottom to top. Due to the effect of gravity, the height of the fin-type hot fluid pipes should not be too high, so that the V-shaped distribution of the fin-type hot fluid pipes can install more fin-type hot fluid pipes at the same height compared to a direct vertical arrangement.

[0021] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0022] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," "the other end," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] like Figures 1 to 6As shown, the energy-saving fin-type hydro-generator air cooler of this embodiment includes a base 1, and a side support plate 6 is installed at the left and right edge positions of the upper end of the base 1. The two side support plates 6 are symmetrically arranged. A plurality of fin-type thermal fluid pipes 7 are installed between the two side support plates 6. There are and only two fin-type thermal fluid pipes 7 on the same horizontal line. The plurality of fin-type thermal fluid pipes 7 are distributed at different heights. A connecting plate 9 is installed between the two fin-type thermal fluid pipes 7 on the same horizontal line. A plurality of vents 8 with a wider bottom and a narrower top are opened inside the connecting plate 9. The lower end of the vent 8 is wider and the upper end of the vent 8 is narrower. A top plate 2 is installed on the upper end of the two side support plates 6. There are multiple fans 3. The airflow compressed once will first contact a fin-type hot fluid pipe 7 and then be blocked by the connecting plate 9. Part of the airflow will move upward through the vent 8 and will be compressed for the second time inside the vent 8. Part of the airflow that has not passed through the vent 8 will continue to move along the connecting plate 9 and then contact another fin-type hot fluid pipe 7 on the same horizontal line. After contact, it will continue to move upward. The airflow compressed for the second time will repeat the screening operation, part of the airflow will continue to be compressed, and part of the airflow will continue to move and contact other fin-type hot fluid pipes 7, so that the airflow entering the device will be compressed and cooled more frequently as the height increases, and will contact the fin-type hot fluid pipe 7, so the heat exchange efficiency will be higher.

[0024] Specifically, an air compression structure 4 is installed between the two side support plates 6 at a position outside the fin-type hot fluid pipe 7. The air compression structure 4 includes an inclined plate 401 and a fixed plate 402. A fixed plate 402 is fixedly installed at both the front and rear ends of the side support plate 6. A plurality of downward-inclined inclined plates 401 are installed between the two fixed plates 402. Under the action of the fan 3, the outside air will enter the interior of the device through the air compression structure 4. Since the spacing between the multiple inclined plates 401 is narrow, the air pressure and density will increase during the circulation process, and the thermal conductivity coefficient with the wall of the inclined plate 401 will increase. Heat is dissipated through the wall of the inclined plate 401, so that the temperature of the air drops.

[0025] Furthermore, the fin-type thermal fluid pipe 7 includes a pipe body 701 and metal fins 702. A plurality of metal fins 702 are evenly distributed on the surface of the pipe body 701. The thermal fluid inside the pipe body 701 transfers heat to the metal fins 702, thereby increasing the contact area with the air through the metal fins 702, thereby increasing the cooling efficiency of the thermal fluid.

[0026] Furthermore, a connecting plate 5 is installed on the outside of the side support plate 6, and multiple finned hot fluid pipes 7 pass through the side support plate 6 and are connected to the connecting plate 5. A pipe inlet 10 communicating with the finned hot fluid pipe 7 is opened at the lower end of one connecting plate 5, and a pipe outlet 11 communicating with the finned hot fluid pipe 7 is opened at the lower end of the other connecting plate 5. The multiple finned hot fluid pipes 7 are distributed in a V shape, and the width of the multiple connecting plates 9 decreases from top to bottom. The hot fluid enters the interior of the connecting plate 5 through the pipe inlet 10 and enters the interior of the finned hot fluid pipe 7 of the lowest layer, and then gradually rises, and finally enters the interior of another connecting plate 5 from the uppermost pipe, and then is discharged from the pipe outlet 11. The hot fluid will pass through all the finned hot fluid pipes 7 from bottom to top. Due to the effect of gravity, the height of the finned hot fluid pipe 7 should not be too high, so that the V-shaped distributed finned hot fluid pipe 7 can install more finned hot fluid pipes 7 at the same height compared to a direct longitudinal arrangement.

[0027] The usage method of this embodiment is as follows: under the action of multiple fans 3, external air enters the two side support plates 6 through the air compression structures 4 on both sides. The airflow compressed once will first contact a fin-type thermal fluid pipe 7, and then be blocked by the connecting plate 9. Part of the airflow will move upward through the vent 8 and will be compressed twice inside the vent 8. Part of the airflow that has not passed through the vent 8 will continue to move along the connecting plate 9, and then contact another fin-type thermal fluid pipe 7 on the same horizontal line. After contact, it will continue to move upward. The airflow compressed twice will repeat the screening operation, part of the airflow will continue to be compressed, and part of the airflow will continue to move and contact other fin-type thermal fluid pipes 7, so that the airflow entering the device will be compressed and cooled more frequently as the height increases, and will contact the fin-type thermal fluid pipe 7, so that the heat exchange efficiency will be higher.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
