Thermal transfer structure with in-plane tube lengths and out-of-plane tube bend(s)

摘要

Cooling apparatuses and coolant-cooled electronic assemblies are provided which include a thermal transfer structure configured to couple to and cool one or more electronic components. The thermal transfer structure includes a thermal spreader, and at least one coolant-carrying tube coupled to the thermal spreader. The coolant-carrying tube(s) includes multiple tube lengths disposed substantially in a common plane, and an out-of-plane tube bend. The out-of-plane tube bend is couples in fluid communication first and second tube lengths of the multiple tube lengths, and extends out-of-plane from the multiple tube lengths disposed in the common plane. The first and second tube lengths may be spaced apart, with a third tube length disposed between them, and the coolant-carrying tube(s) further includes an in-plane tube bend which couples in fluid communication the third tube length and a fourth tube length of the multiple tube lengths.

1. A cooling apparatus comprising:
a thermal transfer structure, the thermal transfer structure comprising:
a thermal spreader;at least one coolant-carrying tube coupled to and in thermal contact with the thermal spreader, the at least one coolant-carrying tube comprising:
multiple tube lengths disposed substantially in a common plane;at last one out-of-plane tube bend, one out-of-plane tube bend of the at least one out-of-plane tube bend coupling in fluid communication a first tube length and a second tube length of the multiple tube lengths, the one out-of-plane tube bend extending out-of-plane from the multiple tube lengths disposed in the common plane;at least one in-plane tube bend, one in-plane tube bend of the at least one in-plane tube bend coupling in fluid communication a third tube length and a fourth tube length of the multiple tube lengths, the one in-plane tube bend extending in the common plane of the multiple tube lengths;wherein the first tube length and the second tube length are spaced apart, with the third tube length of the multiple tube lengths disposed therebetween; andwherein the one out-of-plane tube bend coupling the first tube length and the second tube length overlies, at least in part, and extends out-of-plane from the one in-plane tube bend coupling in fluid communication the third tube length and the fourth tube length; anda support wedge disposed between the one out-of-plane tube bend and the one in-plane tube bend, the support wedge being configured to support the one out-of-plane tube bend.
