Electronic device and frequency converter of motor
First Claim
1. A frequency converter for driving a motor, comprising:
- a circuit board, having at least one first heat-generating element mounted thereon;
at least one second heat-generating element having a main body protruding from the circuit board;
a separating member for separating the at least one portion of the main body of the at least one second heat-generating element from the circuit board, so as to prevent cooling air guided to the at least one second heat-generating element from flowing to the circuit board;
a heat sink, connected to the at least one first heat-generating element;
a fan, facing the heat sink; and
a bracket, for positioning the at least one first heat-generating element relative to the heat sink and the circuit board;
wherein the separating member and the bracket are integrally formed of the same insulating materials.

Abstract
A frequency converter for driving a motor, includes a circuit board, having at least one first heat-generating element mounted thereon; a heat sink, connected to the at least one first heat-generating element; a fan, facing the heat sink; and a bracket, for positioning the at least one heat-generating element relative to the heat sink and the circuit board. The frequency converter includes a separating member for separating at least one portion of at least one second heat-generating element from the circuit board to prevent the cooling air guided to the at least one second heat-generating element from flowing to the circuit board. The frequency converter includes an airflow guiding member for guiding the cooling air from the fan to the heat sink and the at least one second heat-generating element and a flow guiding gate dispensing more airflow to the region corresponding to the at least one first heat-generating element.
