Abstract
A cold chassis and method of making a cold chassis for electronic modules featuring the fabrication of individual brazed cooling ribs each including microchannels along the length thereof and a peripheral flange. A set of adjacent ribs are secured together and assembled onto at least one face of a frame member. The rib flanges are sealed (e.g., friction stir welded) with respect to the frame member.
Claims20
A cold chassis comprising:
- a frame member including multiple patterned adjacent recesses, each recess having a substantially planar portion;
- multiple cooling ribs secured to the frame member, each cooling rib including a peripheral flange and a substantially planar surface, the peripheral flange extending around a circumference of the cooling rib, a surface of the peripheral flange forming part of the substantially planar surface, each cooling rib at least partially disposed in an associated one of the recesses such that the substantially planar surface of the cooling rib contacts the substantially planar portion of the associated recess along at least a majority of a length of the cooling rib;
- and
- a seal securing the peripheral flange of each cooling rib in the associated recess;
- wherein each recess also has first and second ends opposite each other, each end comprising a peripheral ledge;
- and
- wherein a first portion of the peripheral flange of each cooling rib is configured to sit on the peripheral ledge of the first end of the associated recess and a second portion of the peripheral flange of each cooling rib is configured to sit on the peripheral ledge of the second end of the associated recess.

A cold chassis comprising:
- a frame member comprising multiple recesses in a face of the frame member, each recess having a substantially planar portion;
- and
- multiple cooling ribs, each cooling rib having a substantially planar surface and a peripheral flange extending around a circumference of the cooling rib, a surface of the peripheral flange forming part of the substantially planar surface, the peripheral flange at least partially inserted into an associated one of the recesses and placed in thermal contact with the frame member such that the substantially planar surface of the cooling rib contacts the substantially planar portion of the associated recess along at least a majority of a length of the cooling rib;
- wherein each recess also has first and second ends opposite each other, each end comprising a peripheral ledge;
- and
- wherein a first portion of the peripheral flange of each cooling rib is configured to sit on the peripheral ledge of the first end of the associated recess and a second portion of the peripheral flange of each cooling rib is configured to sit on the peripheral ledge of the second end of the associated recess.

A cold chassis comprising:
- a frame member comprising:
- multiple recesses in a face of the frame member, each recess having a substantially planar portion, first and second ends of each recess opposite each other, each of the first and second ends comprising a peripheral ledges in a same plane as the substantially planar portion;
- and
- a supply header and a return header in the face of the frame member, each header located between opposite ends of the recesses such that the recesses extend through the each header;
- and
- multiple cooling ribs in thermal contact with the frame member, each cooling rib comprising:
- a substantially planar surface;
- a peripheral flange extending around a circumference of the cooling rib, a surface of the peripheral flange forming part of the substantially planar surface, the peripheral flange at least partially inserted into an associated one of the recesses and sitting on the peripheral ledges of the associated recess such that the substantially planar surface of the cooling rib contacts the substantially planar portion of the associated recess along at least a majority of a length of the cooling rib, wherein a first portion of the peripheral flange of the cooling rib is configured to sit on the peripheral ledge of the first end of the associated recess and a second portion of the peripheral flange of the cooling rib is configured to sit on the peripheral ledge of the second end of the associated recess;
- an inlet port in fluid communication with the supply header;
- and
- an outlet port in fluid communication with the return header.
