Stationary cooling structure for board/chassis-level conduction cooling

The present disclosure relates to a cold plate and vapor chamber for conduction cooling of one or more printed circuit boards in a printed circuit board (PCB) enclosure. The cold plate may include a planar surface at an oblique angle relative to an axis along which the PCB assembly is inserted into the enclosure. The PCB assembly may include a vapor chamber having a complementary obliquely angled surface. The complementary angled surfaces of the cold plate and vapor chamber may exert forces against each other upon insertion of the printed circuit board assembly into the enclosure and contact between the cold plate and vapor chamber.
