Claim of US Patent No. 11,032,947

1. An apparatus comprising:a coldplate configured to be thermally coupled to a structure to be cooled and to remove thermal energy from the structure;
wherein the coldplate comprises:
first and second outer layers comprising at least one first material; and
a third layer embedded in the first and second outer layers and comprising at least one second material;
wherein the first and second materials have different coefficients of thermal expansion (CTEs);
wherein the third layer is embedded non-uniformly in the first and second outer layers so that different zones of the coldplate have different local CTEs; and
wherein the different zones of the coldplate having the different local CTEs are defined based on different regions of the structure that reach different temperatures.
