Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, specifically a water cooling system for wind turbines. Background Technology

[0002] Wind turbines generate a significant amount of heat during operation, primarily from components such as the generator, converter, and gearbox. Failure to dissipate this heat promptly can lead to excessively high component temperatures, reducing efficiency, shortening lifespan, and even causing malfunctions. The water-cooling system utilizes the flow of water to remove this heat, lowering component temperatures and ensuring the safe and efficient operation of the wind turbine. The water-cooling system for wind turbines aims to effectively cool critical components and maintain temperature balance during long-term operation.

[0003] According to CN215269293U, a water-cooling system suitable for wind power generation is disclosed. This technology discloses "a water-cooling system suitable for wind power generation, relating to the field of wind power water-cooling systems, including a cooling box. Two partitions are fixedly installed on the inner side of the cooling box. An inlet pipe is fixedly installed on one side of the cooling box, and an outlet pipe is fixedly installed on one side of the cooling box. Multiple vent pipes are fixedly inserted into the side walls of the two partitions. An air outlet is provided on one side of the cooling box. A connecting box is fixedly installed on one side of the cooling box. The connecting box is connected to the cooling box via a connecting pipe. Multiple air inlet hoses are fixedly installed on the side wall of the connecting box. A heat collection box is fixedly installed at one end of each air inlet hose. Multiple heat collection pipes are fixedly installed on the side wall of the heat collection box." This technology has the technical effect of "allowing for more precise point-to-point cooling, reducing the temperature in the concentrated area of ​​the heat-generating equipment, and reducing the impact of high temperatures on the service life of the equipment."

[0004] The tube bundle inside the condenser is a key component of the water cooling system, playing a crucial role in the heat exchange process. However, if the tube bundle is only fixed by the tube sheet, there is a large temperature difference between the shell and the tube bundle during the operation of the condenser. Especially under high temperature and high pressure environments, this temperature difference may cause large thermal stress between the tube bundle and the tube sheet, leading to loosening or damage at the connection between the tube bundle and the tube sheet. Furthermore, when the tube bundle needs to be cleaned or replaced, a lot of disassembly work is required, which increases replacement costs and downtime. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a water-cooling system for wind turbine generators. It features increased structural strength of the supporting components, making them more resistant to stresses caused by fluid pressure and temperature changes, thereby improving the stability and safety of the equipment. Furthermore, the internal components can be disassembled from the external components, and multiple components within the internal components can be disassembled, making it convenient to replace damaged parts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water-cooling system for wind turbine generators, comprising a mounting bracket, an evaporator fixed on the mounting bracket, a compressor mounted on the evaporator, and a condenser disposed between the evaporator and the compressor, the condenser comprising:

[0007] External components include a housing fixed to the upper end of the mounting bracket, and flange seats fixed at both ends of the housing;

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

The condenser 4 includes:

[0027] The external component 41 includes a housing 411 fixed to the upper end of the mounting bracket 1, and flange seats 412 fixed at both ends of the housing 411.

[0028] The internal component 42 includes a frame 421 installed inside the housing 411, several tube bundles 422 installed inside the frame 421, several support components 423 fixed inside the frame 421 for fixing the tube bundles 422 in the frame 421, several reinforcing components 424 fixed inside the frame 421 for reinforcing the frame 421, and fixing components 426 installed at both ends inside the housing 411 for fixing the internal component 42 as a whole in the external component 41.

[0029] In this embodiment, during use, the condenser 4 needs to withstand stresses generated by fluid pressure and temperature changes. By increasing the structural strength of the support component 423, it can better resist the effects of these stresses, thereby improving the stability and safety of the equipment. Furthermore, the internal component 42 as a whole can be disassembled from the external component 41, and multiple components inside the internal component 42 can be disassembled, making it convenient to replace parts when they are damaged.

[0030] Specifically, the support assembly 423 includes multiple tube sheets 4231 installed inside the frame 421, mounting rings 4232 fixed to the outer wall of the tube sheets 4231, and mounting holes 4233 opened on the mounting rings 4232 for use with bolts to fix them in the frame 421.

[0031] In this embodiment, the installation ring 4232 is used to improve the overall structural strength of the support component 423 and prevent it from easily deforming and causing damage to the tube bundle 422.

[0032] Specifically, the reinforcement component 424 includes multiple cross brackets 4241 installed inside the frame 421 and located between each adjacent support component 423. The four ends of the cross brackets 4241 are fixed with mounting heads 4242 for use with bolts to fix them in the frame 421.

[0033] In this embodiment, the frame 421 can be reinforced by the support component 423, thereby improving the overall strength of the frame 421.

[0034] Specifically, the internal component 42 also includes a support rod 425 installed inside the frame 421, and the support rod 425 passes through the tube sheet 4231 and the cross bracket 4241.

[0035] In this embodiment, the support rod 425 supports and limits the multiple support components 423 and the reinforcement components 424.

[0036] Specifically, the fixing component 426 includes fixing plates 4261 installed at both ends inside the housing 411, and fixing sleeves 4262 fixed to the center of the inner wall of the fixing plates 4261 for fixing the frame 421 and the support rod 425.

[0037] In this embodiment, when the fixing plate 4261 is fixed by the flange 413, the fixing plate 4261 can be installed and fixed together with the support rod 425 by inserting the fixing sleeve 4262.

[0038] Specifically, the external component 41 also includes flanges 413 installed at both ends of the housing 411, and the flanges 413 and the flange seats 412 are connected by flanges.

[0039] In this embodiment, after the flange 413 is fixed to the flange seat 412 on the housing 411, the flange 413 can fix the frame 421 together with the fixing plate 4261.

[0040] The working principle and usage process of this utility model are as follows: First, during the use of the condenser 4, the interior needs to withstand the stress generated by fluid pressure and temperature changes. The installation ring 4232 improves the overall structural strength of the support component 423, preventing it from easily deforming and causing damage to the tube bundle 422. Furthermore, the support component 423 supports and reinforces the frame 421, improving the overall strength of the frame 421, thereby improving the stability and safety of the equipment.

[0041] When the condenser 4 is under maintenance, the internal component 42 can be disassembled from the external component 41, and multiple components inside the internal component 42 can be disassembled, making it convenient to replace parts when they are damaged.
