Description

Technical Field

[0001] This utility model relates to the field of wind power generation equipment technology, and in particular to a wind turbine generator heat dissipation device. Background Technology

[0002] As a clean and renewable energy source, wind power generation equipment often operates in harsh natural environments. Under high load operation, the generator is prone to generating a lot of heat. If it cannot be dissipated in time, it will seriously affect the generator's working efficiency and service life. Existing wind turbine cooling devices mainly suffer from two problems: First, traditional cooling structures mostly rely on a single air-cooling mode, and the air convection efficiency is significantly constrained by the environment. In particular, the cooling performance drops sharply when the wind speed is low or the air temperature is high, making it difficult to meet the cooling requirements of high-power generators during continuous operation. Second, the generator's operating vibration is transmitted to the cooling box and auxiliary components through rigid connections. Long-term operation can easily cause structural resonance, bolt loosening, or even cracking. At the same time, the vibration also affects the stable operation of the internal cooling fan, further reducing the reliability of cooling. Therefore, it is necessary to design a wind turbine cooling device to solve the above problems. Utility Model Content

[0003] The main objective of this invention is to provide a heat dissipation device for wind turbine generators, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A wind turbine generator cooling device includes a mounting plate, with mounting blocks fixedly connected to all four sides of the outer perimeter of the mounting plate. Shock absorbers are fixedly connected to the four upper corners of the mounting plate. A cooling housing is fixedly connected to the upper ends of the four shock absorbers. Cover plates are fixedly connected to the four upper corners of the cooling housing by bolts. A heat sink is fixedly installed on the right end of the cooling housing by bolts. Multiple ventilation slots are opened on the left, lower, and right ends of the cooling housing.

[0005] Preferably, the heat sink includes an outer shell plate, a liquid storage tank is fixedly connected to the front end of the outer shell plate, a circular shell box is fixedly connected to the middle of the right end of the outer shell plate, a cooling fan is rotatably connected inside the circular shell box, a cooling pipe is fixedly connected inside the outer shell plate, three reinforcing brackets are fixedly connected to the outside of the cooling pipe, and the front and rear ends of the reinforcing brackets are fixedly connected to the outer shell plate, an inlet pipe and a drain pipe are fixedly connected to both ends of the cooling pipe, a switch valve is sleeved on the outer surface of both the inlet pipe and the drain pipe, the other end of the inlet pipe passes through the front side of the outer shell plate and is fixedly installed with the liquid storage tank, an adapter is fixedly connected to the other end of the drain pipe, a circulation pipe is fixedly connected to the lower end of the adapter, a miniature pump is sleeved on the end of the circulation pipe near the liquid storage tank, and the other end of the circulation pipe is fixedly connected to the lower end of the liquid storage tank, and the outer shell plate is fixedly installed on the right end of the heat sink housing by bolts.

[0006] Preferably, the shock absorber includes four rubber seats. An H-shaped support plate is fixedly connected to the inner side of each of the four rubber seats. Multiple heat dissipation fins are fixedly connected to the front and rear parts of the inner wall of the H-shaped support plate. A rubber rod is fixedly connected to the lower end of each rubber seat. A buffer spring is sleeved on the lower part of the outer surface of the rubber rod. A round seat is fixedly connected to the lower end of each buffer spring. The rubber seats are respectively fixedly connected to the four lower corners of the heat dissipation casing.

[0007] Preferably, the ventilation slots are evenly distributed in a rectangular array at the left, lower and right ends of the heat dissipation casing.

[0008] Preferably, the cooling pipes are arranged in a continuous "S"-shaped meandering pattern, the pipe body is fixedly connected to the inner wall of the outer shell plate by three reinforcing brackets, and the cooling pipes are located on the left side of the heat dissipation fan equipment.

[0009] Preferably, the plurality of heat dissipation fins are evenly arranged along the length of the H-shaped support plate, which is located directly below the heat dissipation casing.

[0010] Preferably, the water inlet pipe and the water outlet pipe are horizontally led out from both ends of the cooling pipe and pass through the outer shell plate.

[0011] Preferably, the central axis of the buffer spring coincides with the central axis of the rubber rod, and the round seat is fixedly connected to the upper four corners of the mounting plate by bolts.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, the continuous S-shaped meandering cooling pipes inside the heat sink increase the contact area between the coolant and the airflow. The coolant achieves pre-cooling of the incoming air through closed-loop circulation, which significantly enhances the heat dissipation capacity. The external air forced in by the cooling fan is fully cooled after passing through the cooling pipes and then enters the chassis to carry away the generator's heat. It also forms efficient convection through the multi-directionally evenly distributed ventilation slots, thereby greatly improving the heat dissipation efficiency and ensuring that the generator can still operate stably under high temperature or low wind speed conditions.

[0013] 2. In this utility model, the buffer spring and the rubber rod are coaxially coupled to give full play to the elastic shock absorption effect, so as to avoid the loosening or fatigue damage of the heat sink and its internal connecting structure caused by vibration. At the same time, the H-shaped support plate and the evenly distributed heat dissipation fins in the shock absorber provide stable support and further assist in airflow organization and heat dissipation, realizing the organic combination of shock absorption and heat dissipation, and significantly improving the reliability of the overall device.

Multiple ventilation slots 7 are opened on the left, lower and right ends of the heat dissipation casing 4. The ventilation slots 7 are evenly distributed in a rectangular array on the left, lower and right ends of the heat dissipation casing 4.

[0020] Through the above scheme: the wind turbine generator heat dissipation device is installed stably as a whole by mounting plate 1 and mounting blocks 2 on the outer perimeter. The shock absorbers 3 at the four corners of the upper end of the mounting plate 1 support the heat dissipation box 4.

The outer shell plate 62 is fixedly installed on the right end of the heat dissipation box 4 by bolts. The cooling pipe 65 is distributed in a continuous "S" shape. The pipe body of the cooling pipe 65 is fixedly connected to the inner wall of the outer shell plate 62 by three reinforcing brackets 69.
