Abstract

The invention discloses a vertical power terminal double-sided heat dissipation power module, and the powe rmodule comprises a power module body; the power module body comprises a first insulating substrate and a second insulating substrate which are oppositely arranged, and a plurality of chips and conductive connecting blocks which are arranged between the two insulating substrates; the lower surface of the chip is connected with the first insulating substrate through a connecting layer, the upper surface of the chip is connected with a conductive connecting block through a connecting layer and electrically connected with the first insulating substrate through a metal wire, and the upper surface of the conductive connecting block is connected with the second insulating substrate through a connecting layer; a power terminal and a control terminal are arranged on the first insulating substrate, an arc-shaped hole is formed in a weld leg, connected with the first insulating substrate, of the power terminal, and one end, far away from the arc-shaped hole, of the power terminal is bent towards one side of the first insulating substrate and is perpendicular to the first insulating substrate, so that the power terminal becomes a vertical power terminal; and the first insulating substrate and the second insulating substrate are subjected to injection molding processing through an epoxy plastic package body.

Description

technical field [0001] The invention relates to the field of power electronics, in particular to a double-sided cooling power module with vertical power terminals. Background technique [0002] With the increasing miniaturization requirements of the new energy automobile industry for power modules, the heat dissipation conditions of the modules are becoming more and more severe. Since the power terminals of the planar horizontal double-sided heat dissipation module are parallel to the heat dissipation and insulation substrate of the module, the installation method is limited. In the existing double-sided heat dissipation power modules on the market, most of their insulating substrates are set in parallel with the same shape and size, but the modules with the same shape and size are easily restricted in the internal layout and later installation of the module, so the vertical power terminal The invention of the double-sided cooling power module supplements and enriches the i...
