[0017] A heat dissipation component for a wind power converter, referring to Figure 1-4, including a cabinet 11 and a convergence box 22. In the cabinet 11 doubly fed wind turbine, the excitation device added to the rotor side has the main function of controlling the amplitude, phase, frequency, etc. of the excitation through the converter when the rotor speed n changes, so that the stator side can input constant frequency electricity to the grid. Three cavities 12 are opened inside the cabinet 11. Component boxes 15 are installed inside the three cavities 12. The three component boxes 15 contain multiple components such as machine-side inductors, machine-side power modules, grid-side power modules, grid-side inductors and grid-side switches.

The mounting member 3 consists of two mounting plates 31 and four bolts 32. The two mounting plates 31 are welded to the two sides of the convergence box 22 respectively. The four bolts 32 The threads are respectively passed through two corners of the two mounting plates 31, and the four bolts 32 are all threadedly connected to the cabinet 11, so that the convergence box 22 is fixedly installed on the top of the cabinet 11. The bottom end of the convergence box 22 is bonded with a circular rubber pad 24, and the bottom end surface of the circular rubber pad 24 fits tightly with the top surface of the cabinet 11, which can increase the sealing between the convergence box 22 and the cabinet 11 and prevent air leakage. Two exhaust fans 23 are installed on the top of the convergence box 22. Both exhaust fans 23 are electrically connected to the external power supply through the control switch. The two exhaust fans 23 are preferably SY-FYSJ01 type, and the air outlets of the two exhaust fans 23 are They are all connected to the convergence box 22, and the air outlets of the two exhaust fans 23 are both connected to a heat exhaust pipe 41.
