Cooling heat exchanger assembly

Separated process/heat-sink channels with verified leak/thermal transfer interface; discovery hypothesis, capability and compatibility unreviewed.

Discovered · unresearchedClosure: OpenInventory incomplete

Capability requirements and tolerances

Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.

Making outline

Form separated copper process/sink channels and headers, braze seams and support them mechanically; independently test both sides for leaks and thermal transfer with separately allocated water flow.
Detailed procedure and acceptance remain unresearched.

What remains unresolved

Manufacture, quantities, suitability and complete inventory remain unreviewed.
Current memory-first method needs source and compatibility review.
