1. A semi-conductor assembly, comprising:
- an elongated, electrically isolated metallic support structure of generally rectangular cross section, said structure containing therein an enclosed coolant conduit spanning the length of said support structure, said conduit being of generally rectangular cross-section, the width dimension of said conduit being greater than its height;
a semi-conductor device mounted on at least one exterior surface of said structure, said device being bonded in a thermally intimate manner to said surface of said structure opposing said width dimension of said conduit and being placed opposing a concave curved heat transfer segment of the surface of said conduit;
first circuit means extending along and spaced from said structures, for providing electrical control to said semi-conductor device;
second circuit means, expending along and spaced from said structure, for carrying current from said semi-conductor device; and
electrical interconnect means for connecting said semi-conductor device to said first and second circuit means.

Abstract
A semi-conductor assembly including an elongated electrically conductive support structure defining a sinuous coolant flow path between respective upper and lower surfaces of the support structure. The sinuous coolant path includes alternating concave and convex coolant surfaces. A first series of semi-conductor devices is secured in a thermally intimate manner to the upper surface of the support structure, and a second series of semi-conductor devices is secured in a thermally intimate manner to the lower surface of the support structure. Each semi-conductor device is disposed proximate a concave curved surface of the coolant path.

7. A semi-conductor assembly, comprising:
-
an elongated electrically conductive support structure having oppositely disposed upper and lower surfaces and an enclosed, substantially sinuous coolant flow path spanning the length thereof intermediate said upper and lower surfaces, said coolant flow path having a first width greater than its height; a first series of semi-conductor devices spaced apart along the length of said upper surface of said support structure, disposed in intimate thermal contact therewith and electrically connected thereto; a second series of semi-conductor devices spaced apart along the length of said lower surface of said support structure, disposed in intimate thermal contact therewith and electrically connected thereto; and means for directing liquid coolant through said coolant flow path to thereby remove thermal energy from said first and second series of semi-conductor devises; wherein said first and second series of semi-conductor devices each comprise at least one semi-conductor device having a width not exceeding said first width and disposed in a substantially symmetric overlying relationship with said coolant flow path. - View Dependent Claims (8, 9, 10, 14)
