US 2022/0102243 A1 · ELEMENT MODULE

Abstract

An element module includes a cooler, a plurality of elements, and a conductive member. The cooler includes a first element disposition portion and a second element disposition portion which are provided on both sides in a predetermined direction. The plurality of elements are disposed in each of the first element disposition portion and the second element disposition portion. The conductive member is disposed in a space portion of the cooler. The space portion penetrates the cooler between the plurality of elements in each of the first element disposition portion and the second element disposition portion. The space portion allows the first element disposition portion and the second element disposition portion to communicate with each other. The conductive member is connected to the element of the first element disposition portion and the element of the second element disposition portion.

An element module, comprising:

a cooler including a first element disposition portion and a second element disposition portion which are provided on both sides in a predetermined direction, and including at least one refrigerant storage portion configured to internally store a refrigerant between the first element disposition portion and the second element disposition portion;
a plurality of elements disposed in each of the first element disposition portion and the second element disposition portion, and including transistors;
a conductive member disposed in a space portion through which the first element disposition portion and the second element disposition portion are allowed to communicate with each other by penetrating the cooler between the plurality of elements in each of the first element disposition portion and the second element disposition portion, and connected to the element of the first element disposition portion and the element of the second element disposition portion;
a plurality of conductor plates disposed on a side opposite to each facing side of the first element disposition portion and the second element disposition portion, and to which the plurality of elements are connected;
and
a plurality of gate lines connected to a gate of each of the transistors,
wherein the space portion is formed in a long slit shape along a flow direction of the refrigerant in the refrigerant storage portion,
each of the first element disposition portion and the second element disposition portion is divided into two portions on both sides in a direction orthogonal to the flow direction of the refrigerant across the space portion, and thereby, the refrigerant storage portion has two of refrigerant storage portions,
each of the transistors is disposed in line along the flow direction of the refrigerant in each divided portion of the first element disposition portion and the second element disposition portion, and
the plurality of gate lines intersect with a current path in each of the conductor plates.
