| description | The invention discloses an elevator frequency converter heat dissipation device and a maintenance method thereof. The elevator frequency converter heat dissipation device comprises a frequency converter unit and a heat dissipation assembly. The frequency converter unit comprises a power module, a radiator, a driving electronic board, a bus capacitor board and a frequency converter substrate; the power module is mounted on the radiator, the driving electronic board is welded on a leading-out pin of the power module, and the bus capacitor board and the radiator are both mounted on the frequency converter substrate to form a closed radiating air duct of the frequency converter; the heat dissipation assembly is detachably installed on the frequency converter substrate. The heat dissipation assembly is installed on the frequency converter substrate in a drawable mode through the drawer type installation structure, when the heat dissipation fan needs to be replaced, the whole frequency converter does not need to be |
