Description

Technical Field

[0001] This application relates to the field of wind power converter technology, and more particularly to a mounting frame and a wind power converter. Background Technology

[0002] As a crucial component of wind power generation systems, wind turbine converters perform multiple functions, including power conversion, grid-connected power transmission, and fault protection, placing high demands on their reliability and safety. The ambient temperature inside the wind turbine converter cabinet and the temperature rise of its components are directly related to the overall reliability of the unit. With the continuous increase in the overall power of the converter, its heat loss also increases, placing higher demands on the heat exchange within the cabinet.

[0003] To transfer heat from inside the wind turbine converter to the outside, a combination of fan and heat exchanger is typically used. Furthermore, to fully utilize the heat exchanger's fins, the fan and heat exchanger must be installed together, avoiding separate layouts. The fan inside the converter operates continuously at high ambient temperatures, making it a vulnerable component requiring frequent maintenance; while the liquid-cooled heat exchanger's fins may leak due to manufacturing processes. Additionally, due to the inductors and other components within the wind turbine converter, as well as the influence of the installation environment, the fan assembly must withstand the vibrations of the entire unit. This places high demands on the strength, rigidity, and maintainability of the fan assembly. Utility Model Content

[0004] In view of this, the purpose of this application is to provide an installation frame and a wind power converter to solve the strength and vibration resistance problems when the fan assembly and heat exchanger are side-mounted together, improve the utilization efficiency of the heat exchanger fins, improve the maintainability of the fan assembly, and reduce the impact of coolant leakage on other devices.

[0005] The technical solution adopted in this application to solve the above-mentioned technical problems is as follows:

[0006] According to one aspect of the embodiments of this application, a mounting frame is provided for mounting a fan assembly and a heat exchanger; the mounting frame includes a bracket having a top plate, a bottom plate, a first column, and a second column;

[0007] The first column and the second column are spaced apart, and one end of the first column and the second column are connected to one side of the top plate, and the other end of the first column and the second column are connected to one side of the bottom plate.

[0008] The bracket has guide rails disposed on the top plate and / or the bottom plate, and support members disposed on the bottom plate. The fan assembly is assembled in the bracket via the guide rails, and the heat exchanger is assembled in the bracket and fixed on the bracket via the support members.

[0009] In one example, the bracket is a one-piece bent structure.

[0010] In one example, the mounting frame further includes a brace, one end of which is connected to the first column or the second column, and the other end of which is connected to the top plate or the bottom plate.

[0011] In one example, the mounting frame further includes a limiting plate for limiting the fan assembly and / or the heat exchanger.

[0012] In one example, the mounting frame further includes a water collection tray located outside the bracket and mounted on the base plate, the water collection tray being used to collect coolant dripping or falling from the heat exchanger.

[0013] In one example, the water tray has an outlet for connection to an external drainage component.

[0014] In one example, the mounting frame further includes a mounting plate, through which one side of the water tray is mounted on the base plate.

[0015] In one example, the fan assembly and the heat exchanger are arranged sequentially along the thickness direction of the mounting frame.

[0016] According to another aspect of the embodiments of this application, a wind power converter is provided, including a cabinet and the aforementioned mounting frame, wherein the other side of the top plate and the bottom plate are connected to the cabinet.

[0017] In one example, the fan assembly is fixed to the cabinet.

[0018] The mounting frame and wind power converter provided in this application embodiment assemble the fan assembly into the bracket via guide rails, and assemble the heat exchanger into the bracket via support members and fix it on the bracket. On the one hand, this improves the rigidity of the overall structure, meets the strength requirements of side-mounted installation, and complies with the requirements of the vibration environment for installation. On the other hand, the fan assembly and heat exchanger are easy to install and disassemble, and can be maintained independently without affecting each other, thus improving maintainability.

[0027] like Figures 1-2 As shown, one embodiment of this application provides an installation frame for mounting a fan assembly 31 and a heat exchanger 32; the installation frame includes a bracket 11, the bracket 11 having a top plate 111, a bottom plate 112, a first column 113 and a second column 114;

[0028] The first column 113 and the second column 114 are spaced apart, and one end of the first column 113 and one end of the second column 114 are connected to one side of the top plate 111, and the other end of the first column 113 and the other end of the second column 114 are connected to one side of the bottom plate 112.

[0029] The bracket 11 has guide rails 12 disposed on the top plate 111 and / or the bottom plate 112, and support members 13 disposed on the bottom plate 112. The fan assembly 31 is assembled in the bracket 11 via the guide rails 12, and the heat exchanger 32 is assembled in the bracket 11 and fixed to the bracket 11 via the support members 13. The heat exchanger 32 can be fixed to the first column 113 or the second column 114 by fasteners.

[0030] The fan assembly is mounted in the bracket 11 via the guide rail 12, and the heat exchanger 32 is mounted in the bracket 11 via the support 13 and fixed on the bracket 11. The fan assembly 31 and the heat exchanger 32 are installed independently, which is convenient for installation and allows for independent maintenance without affecting each other.

[0031] In one example, the bracket 11 is an integral bent structure.

[0032] In one example, the mounting frame further includes a diagonal brace 14, one end of which is connected to the first column 113 or the second column 114, and the other end of which is connected to the top plate 111 or the bottom plate 112.
