[0016] Please see Figures 1-3 This utility model provides a technical solution: a heat dissipation device for preventing the frequency converter of an induced draft fan from overheating, including a machine room 1 for protection, a cabinet 2 for storage on the inner wall of the machine room 1, and a louver 3 for air intake connected through one side of the inner wall of the machine room 1. A ventilation duct 6 for air exhaust is bolted to the upper surface of the cabinet 2. The ventilation duct 6 is connected through the front part of the inner wall of the machine room 1, and a screen 7 for interception is abutted at the end of the ventilation duct 6. A baffle 8 for limiting the screen 7 is abutted below the screen 7. The baffle 8 is bolted to the end of the ventilation duct 6. A filtration and impurity removal mechanism 4 is provided on the inner wall of the machine room 1 near the louver 3, and a collection mechanism 5 for collection is provided below the filtration and impurity removal mechanism 4.

[0017] The heat dissipation device that prevents the frequency converter of the exhaust fan from overheating is installed in the cabinet 2, where the frequency converter and other electrical equipment are installed. When the ventilation fan 402 is running, outside air enters the computer room 1 through the louvers 3, and then enters from the front of the cabinet 2 to carry away the heat generated by the frequency converter and other electrical equipment inside the cabinet 2. The hot air is then discharged into the ventilation duct 6 and then discharged to the outside through the ventilation duct 6 for circulation. The cabinet 2 and the downward-facing ventilation duct 6 prevent rainwater from entering. The mesh 7 is squeezed between the ventilation duct 6 and the baffle 8 to prevent insects from entering the computer room 1.

The semi-filter 406 is slidably connected to the inner wall of the support frame 403 by a groove.

[0019] The heat dissipation device that prevents the frequency converter of the induced draft fan from overheating involves the ventilation fan 402 drawing outside air into the frame 401 through the louvers 3 during operation. After being filtered by the semi-filter 406, the air enters the machine room 1. Impurities in the air adhere to one side of the semi-filter 406. The motor controller periodically starts the drive motor 404 for a period of time.

The card plate extending from the drawer lock a409 engages in the slot on the inner wall of the port 407. After turning the drawer lock a409 with a key, the card plate is pulled out from the slot, thereby pulling the baffle 408 out of the port 407, and then the support frame 403 is pulled out.

[0022] exist Figure 2 and Figures 4-6 In the middle, the collecting mechanism 5 includes a limiting frame 501 with the bottom of the square frame 401 abutting. The limiting frame 501 is bolted to one side of the inner wall of the machine room 1. A collection box 502 for collecting impurities is slidably connected to the inner wall of the limiting frame 501. A drawer lock b503 for limiting is connected through the front part of the inner wall of the collection box 502. The drawer lock b503 is engaged in the slot on the inner wall of the limiting frame 501.

[0023] The heat dissipation device that prevents the induced draft fan inverter from overheating collects impurities scraped off by the rotating spiral scraper 405 into the collection box 502. The inner wall of the limiting frame 501 has a slot, and the card plate extending from the drawer lock b503 engages in the slot on the inner wall of the limiting frame 501.
