Description

Technical Field

[0001] This utility model relates to the field of air-water cooler technology, specifically an air-water cooler for generators. Background Technology

[0002] In large and medium-sized motors, coolers are essential heat dissipation devices. Their main function is to absorb and exchange the heat generated during motor operation, keeping the motor temperature within a specified range. Air-water coolers are commonly used in motor ventilation and heat dissipation systems. An air-water cooler is a highly efficient, environmentally friendly, and energy-saving closed-loop cooler capable of heat exchange cooling. Due to its completely mechanical design, it is simpler than air conditioners and other electrical and electronic equipment, offering significant safety and reliability. The principle is that hot air from the motor enters the air-water cooler through the air inlet window, and then the cooling water pipes inside the cooler core exchange heat with the hot air through a non-medium-contact process, directly carrying away the motor's heat.

[0003] According to the search, the patent application number (201820151633.6) discloses "an air-water cooler for motors". By setting multiple air ducts inside the cold water tank, the effect of water surrounding air can be achieved. The hot air and the cold water outside the ducts can be in full contact, which effectively improves the heat exchange efficiency and has a significant cooling effect.

[0004] However, the aforementioned devices have the following problems: the existing pipe connection components are relatively complex. Improper installation during pipe connections can lead to leaks and seepage, affecting equipment performance and potentially causing safety accidents. Due to the complexity of the components, maintenance is also cumbersome, hindering regular pipe cleaning, inspection, and replacement of worn parts. Failure to perform timely maintenance may shorten equipment lifespan or reduce performance. Therefore, we propose a generator air-water cooler solution to address these issues. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-4 One embodiment of this utility model provides an air-water cooler for a generator, comprising a housing 1, four sets of support rods 2 fixedly connected inside the housing 1, a partition 3 fixedly connected to the bottom of the support rods 2, and a heat exchange assembly 4 disposed within the partition 3.

[0024] The heat exchange assembly 4 includes a mounting bracket 41, a heat exchanger 42, an inlet pipe 43, an outlet pipe 44, and a drain port 45. The mounting bracket 41 is provided inside the outer casing 1. The heat exchanger 42 is fixedly installed inside the mounting bracket 41. The inlet pipe 43 is fixedly connected to the left end of the heat exchanger 42. The outlet pipe 44 is fixedly connected to the left end of the heat exchanger 42 in front of the inlet pipe 43. The drain port 45 is connected to the right end of the heat exchanger 42. The mounting assembly 5 is provided on the right side of the outer casing 1.

[0025] This device, by incorporating a heat exchange component 4 and a fixing component 5, solves the problems of existing pipeline connection components being relatively complex, improper installation affecting equipment performance, and being unfavorable for regular disassembly and cleaning of pipelines, inspection and replacement of worn parts.

[0026] Furthermore, the fixing component 5 includes a fixing tube 51, a first positioning hole 52, an adjusting ring 53, an internal gear 54, a pinion 55, a connecting rod 56, and a clamping plate 57. The fixing tube 51 is fixedly connected to the right side of the outer casing 1. The fixing tube 51 has a first positioning hole 52 inside. The adjusting ring 53 is rotatably connected to the outer surface of the fixing tube 51. The internal gear 54 is fixedly connected to the inner side of the adjusting ring 53. Six sets of pinions 55 are arranged in a ring array inside the fixing tube 51. The pinions 55 mesh with the internal gear 54. The connecting rod 56 is fixedly connected to the left side of the pinions 55. The clamping plate 57 is fixedly connected to the left end of the connecting rod 56. The clamping plate 57 is blade-shaped and has anti-slip textures on its inner wall. Figure 4 As shown, this structure is used to adjust the inner diameter of the fixed pipe 51 by rotating the adjusting ring 53, through the meshing of the internal gear 54 and the pinion 55, so that the internal gear 54 drives the six sets of pinions 55 and the clamping plate 57 to rotate simultaneously, so that the inner wall of the clamping plate 57 fits with the connecting pipe, thereby quickly fixing the pipe at the drain interface 45. Conversely, rotating the adjusting ring 53 can release the locking of the connecting pipe, making it easier to clean and maintain the connecting pipe.

[0027] Furthermore, two sets of automatic exhaust pipes 6 are fixedly installed on the left side surface of the mounting bracket 41. The automatic exhaust pipes 6 are connected to the heat exchanger 42. A protective frame 7, which is U-shaped, is fixedly connected to the left side of the mounting bracket 41 outside the automatic exhaust pipes 6. Figure 1 As shown, this structure is used to discharge the gas from the heat exchanger 42 through the automatic exhaust pipe 6, ensuring that the internal pressure balance is further balanced, will not be disturbed, and has high reliability.

[0028] A fixing plate 8 is fixedly connected to the bottom perimeter of the outer casing 1. Several sets of first connecting holes 9 are equidistantly arranged inside the fixing plate 8, and four sets of second positioning holes 10 are arranged at the center of the perimeter of the outer casing 1. For example... Figure 2 As shown, this structure is used to facilitate the installation and fixation of the outer casing 1 through the first connecting hole 9 opened at the fixing plate 8.

[0029] Furthermore, four sets of connecting plates 11 are fixedly connected to the outer side of the fixing bracket 41 inside the outer casing 1, and the inner walls of the connecting plates 11 are fixedly connected to the inner wall of the outer casing 1 through several sets of second connecting holes 12. Figure 3 As shown, this structure is used to enhance the fixing effect between the outer shell 1 and the fixing frame 41 through the connecting plate 11 and the second connecting hole 12 on the inner wall of the fixing frame 41.

[0030] Furthermore, two sets of limiting rings are fixedly connected to the left and right sides of the adjusting ring 53, and a sliding groove adapted to the limiting ring is opened inside the fixing tube 51. Figure 4 As shown, this structure is used to ensure that the adjusting ring 53 rotates stably inside the fixed tube 51 by means of a limiting ring, so as to prevent the adjusting ring 53 from detaching from the inside of the fixed tube 51.

[0031] Furthermore, four sets of lifting rings 13 are fixedly connected to the four corners of the top of the outer casing 1. For example... Figure 2 As shown, this structure facilitates the transport and transfer of the device via four sets of lifting rings 13.

[0032] Working principle: When using, such as Figure 2 As shown, this device is installed on the generator in a conventional installation manner through the first connecting hole 9 at the fixing plate 8. Figure 3 and Figure 4 As shown, the connecting pipe is then inserted into the outside of the drain interface 45. The adjusting ring 53 is then rotated, causing the internal gear 54 and pinion 55 to mesh. This drives the six sets of pinions 55 and the clamping plate 57 to rotate simultaneously, adjusting the inner diameter of the fixing pipe 51 so that the inner wall of the clamping plate 57 fits against the connecting pipe, thus quickly fixing the pipe at the drain interface 45. Conversely, rotating the adjusting ring 53 releases the locking of the connecting pipe, facilitating cleaning and maintenance. Figure 1 and Figure 2 As shown, water is then introduced into the water inlet pipe 43 at the heat exchanger 42, and the airflow undergoes heat exchange through the heat exchanger 42, and enters the motor through the bottom of the outer casing 1. The above is the complete working principle of this utility model.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
