RESISTOR, HEAT DISSIPATER, AND COMBINATORY DEVICE OF RESISTOR AND HEAT DISSIPATER

摘要

The present invention relates to the field of power electronics, and discloses a resistor, a heat dissipater, and a combinatory device of the resistor and the heat dissipater. The resistor is columnar and comprises a metal terminal, an insulating part, a casing, a metal rod, a resistor wire, thermally conductive fillers, and a metal connection mechanism. The metal connection mechanism of the resistor and the heat dissipater are connected by direct contact. The structure and connection method shorten the length of a resistor, completely insulate the electric circuits of the resistor from the possible leakage of the water inlet and outlet pipes of the heat dissipater, and enable the combinatory device of the resistor and the heat dissipater to be structurally more compact and the connections thereof cleaner.
