Description

Brushless controller heat dissipation casing

Technical Field

The utility model relates to the technical field of brushless controller heat dissipation, in particular to a brushless controller heat dissipation shell.

Background

The brushless controller adopts MOS tubes to conduct and control the current direction in turn, so as to drive the motor to rotate; in the application of an electric tool, the working current is generally larger, and because the MOS tube has internal resistance, heat can be generated during working, the self heat-dissipation capacity is limited, and when the temperature reaches a certain height, the MOS tube can be damaged; in order to enable the heat of the MOS tube to be radiated as soon as possible, large-area metal lamination is needed to help radiating; copper sheets, aluminum profiles and aluminum shells are commonly used; in the electric tool, the aluminum shell is used more, because the inner space of the electric tool shell is limited, the aluminum shell not only can fix the MOS tube, but also can play a role in heat dissipation.

After being installed in a shell of a complete machine, the bottom of the aluminum shell is almost in flat contact with the plastic shell, and no ventilation space exists, so that the heat dissipation effect is poor.
