Description

Technical Field

[0001] This utility model relates to the field of radiator technology, specifically a water-cooled backpack radiator. Background Technology

[0002] The nacelle transformer of a wind turbine is a core component of a wind power generation system. Its main function is to convert the low-voltage electrical energy generated by the wind turbine into high-voltage electrical energy that meets the grid standards. During operation, the nacelle transformer usually needs to be equipped with a heat dissipation structure to cool the transformer. However, the existing heat dissipation structure of the transformer usually consists of several fins on the transformer body. The heat exchange area is increased by the fins, but the heat dissipation efficiency is relatively poor and it is not conducive to the rapid cooling of the transformer. Utility Model Content

[0003] The purpose of this invention is to provide a water-cooled backpack radiator to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A water-cooled backpack radiator includes an upper air chamber, a radiator core at the bottom of the upper air chamber, a middle air chamber fixedly connected to the bottom of the radiator core, a lower air chamber fixedly connected to the bottom of the middle air chamber, two centrifugal fan impellers inside the lower air chamber, and a motor at the bottom of each centrifugal fan impeller, the motor driving the centrifugal fan impellers to rotate.

[0006] Furthermore, the upper wind chamber is fixedly connected to a protective net one on one side of its opening, and the lower wind chamber is fixedly connected to a protective net two on one side of its opening.

[0007] Furthermore, a baffle is fixedly connected to one side of the opening of the central air chamber, and the baffle is fixed to the bottom of the radiator core to block the opening of the central air chamber.

[0008] Furthermore, the bottom of the upper air chamber and the top of the middle air chamber are both inclined, and the radiator core is inclined between the upper air chamber and the middle air chamber.

[0009] Furthermore, two guide grooves are provided on the top surface of the lower air chamber corresponding to the two centrifugal fan impellers, and a guide ring is fixedly connected inside the guide groove, with the bottom of the guide ring extending into the interior of the adjacent centrifugal fan impeller.

[0010] Preferably, the centrifugal fan impeller has a mounting plate at its bottom that is fixedly connected to the motor.

[0011] Furthermore, a pad that is fixedly connected to the bottom of the lower air chamber is fixedly connected to the mounting plate. The mounting plate is fixed to the pad with screws, and the pad is fixed to the bottom of the lower air chamber with screws.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By installing a radiator core at the bottom of the upper air chamber, the radiator can be installed on the side of the transformer. A centrifugal fan draws hot air in through the air inlet of the upper air chamber, and the hot air passes through the radiator core. The inlet and outlet of the radiator core are connected to pipes, and water circulation and cooling occur inside the radiator core. In this way, the hot air is water-cooled through the radiator core, and the cold air enters the lower air chamber through the middle air chamber. The cold air is discharged from the air outlet by the centrifugal fan, which cools the transformer in the nacelle. The radiator effectively cools the transformer, which improves the heat dissipation efficiency. Furthermore, since the air velocity at the air outlet is greater than that at the air inlet, the cold air is at the bottom and the hot air is at the top inside the radiator. At the same time, the air outlet of the centrifugal fan is designed at the bottom of the radiator, which makes the heat dissipation of the transformer in the nacelle more uniform, thus improving the heat dissipation efficiency.

[0019] 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.

[0020] Please see Figure 1-3 In this embodiment of the utility model, the water-cooled backpack radiator includes an upper air chamber 10, a radiator core 40 at the bottom of the upper air chamber 10, a middle air chamber 20 fixedly connected to the bottom of the radiator core 40, and a lower air chamber 30 fixedly connected to the bottom of the middle air chamber 20. The upper air chamber 10, the radiator core 40, the middle air chamber 20, and the lower air chamber 30 are connected sequentially from top to bottom. The lower air chamber 30 is provided with two centrifugal fan impellers 50. A motor 52 is provided at the bottom of the centrifugal fan impellers 50, and the motor 52 can drive the centrifugal fan impellers 50 to rotate. A baffle 21 is fixedly connected to one side of the opening of the middle air chamber 20. The baffle 21 is fixed to the bottom of the radiator core 40 and blocks the opening of the middle air chamber 20.

[0021] Specifically, the radiator can be installed on the side of the transformer. The centrifugal fan impeller 50 is driven by the motor 52 to rotate, so that the centrifugal fan draws in hot air from the air inlet of the upper air chamber 10. The hot air in the upper air chamber 10 flows downward through the radiator core 40. The inlet and outlet of the radiator core 40 are connected to pipes, and water circulation and cooling are carried out inside the radiator core 40. In this way, the hot air can be water-cooled through the radiator core 40. After passing through the radiator core 40, the cold air enters the middle air chamber 20. The cold air can enter the lower air chamber 30 from the middle air chamber 20, and then the cold air is discharged from the air outlet of the lower air chamber 30 by the centrifugal fan. The cold air cools the transformer in the engine room. The radiator actively dissipates heat from the transformer, which helps to improve the heat dissipation efficiency.

[0022] Since the air inlet area of ​​the upper air chamber 10 is larger than the air outlet area of ​​the lower air chamber 30, the air velocity at the air outlet of the lower air chamber 30 is greater than the air velocity at the air inlet of the upper air chamber 10. Hot air enters the upper part of the radiator from the upper air chamber 10, while cold air flows out from the bottom of the lower air chamber 30. In this way, the cold air inside the radiator is at the bottom and the hot air is at the top. At the same time, designing the air outlet of the centrifugal fan to be at the bottom can make the heat dissipation of the transformer in the nacelle more uniform, which is conducive to improving the heat dissipation efficiency.

[0023] Example 1

[0024] like Figure 1 As shown, in this embodiment, a protective net 11 is fixedly connected to one side of the upper air chamber 10 at its opening, and a protective net 31 is fixedly connected to one side of the lower air chamber 30 at its opening. The protective net 11 is located at the air inlet of the upper air chamber 10, while the protective net 31 is located at the air outlet of the lower air chamber 30.

[0025] In practice, the upper wind chamber 10 can be protected by protective net 11, while the lower wind chamber 30 can be protected by protective net 2, which helps prevent foreign objects from entering and improves the overall operational stability of the machine.

[0026] like Figure 1-3As shown, in this embodiment, the bottom of the upper air chamber 10 and the top of the middle air chamber 20 are both inclined, and the radiator core 40 is inclined between the upper air chamber 10 and the middle air chamber 20.

[0027] In practice, by tilting the radiator core 40, the thickness of the upper air chamber 10 and the middle air chamber 20 can be reduced while the radiator core 40 is aligned with the interior of the upper air chamber 10 and the middle air chamber 20, which helps to reduce the overall thickness of the radiator.

[0028] like Figure 2-4 As shown, in this embodiment, two guide grooves 33 are provided on the top surface of the lower air chamber 30 corresponding to the two centrifugal fan impellers 50. A guide ring 32 is fixedly connected inside the guide groove 33. The top edge of the guide ring 32 is fixed to the top surface of the lower air chamber 30, and the bottom of the guide ring 32 extends into the interior of the adjacent centrifugal fan 50.

[0029] In practice, the cold air in the central stroke chamber 20 can enter the centrifugal fan through the air guide ring 32. The air guide ring 32 guides the cold air, and the top of the lower air chamber 30 and the air guide ring 32 separate the interior of the central stroke chamber 20 from the interior of the lower air chamber 30, which is conducive to the centrifugal fan smoothly drawing in the cold air in the central stroke chamber 20.

[0030] Example 2

[0031] Based on Example 1, such as Figure 3 and Figure 4 As shown, in this embodiment, the centrifugal fan impeller 50 has a mounting plate 51 at its bottom that is fixedly connected to the motor 52. A diagonal brace is fixedly mounted at the bottom of the mounting plate 51, and the motor 52 is fixedly mounted on the diagonal brace. The motor 52 is fixed to the mounting plate 51 by the diagonal brace. The bottom of the lower air chamber 30 is fixedly connected to a pad 60 that is fixedly connected to the mounting plate 51. The mounting plate 51 is fixed to the pad 60 by screws, and the pad 60 is fixed to the bottom of the lower air chamber 30 by screws.

[0032] In practice, the motor 52 can be connected to the lower air chamber 30 via the mounting plate 51, and the mounting plate 51 can be fixed to the bottom of the lower air chamber 30 via the pad 60, thereby connecting the centrifugal fan 50 and the motor 52 to the lower air chamber 30. When different sizes of centrifugal fans need to be selected, the corresponding size of the pad 60 can be configured. The impellers 50 of centrifugal fans of different sizes and models and the motor 52 can be fixed to the lower air chamber 30 via the pad 60. The pad 60, the mounting plate 51, and the motor 52 form a modular design, which is convenient for later operation, maintenance or replacement.

[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.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
