Compliant cooling plates

A cooling plate comprising:

• a housing including a first section and a second section;
• a diaphragm including a contact surface, the housing supporting the diaphragm, and the housing and the diaphragm collectively defining a chamber enclosed relative to the contact surface;
• a plurality of ribs disposed, in the chamber, between the first section of the housing and the second section of the housing;
• at least one fin including a first end portion and a second end portion, the first end portion coupled to the diaphragm with the second end portion in the chamber, and the at least one fin and the plurality of ribs collectively defining a plurality of channels in the chamber, and at least one portion of the at least one fin movable toward the housing in response to external pressure on the contact surface;
• and
• a baffle defining at least one recess, wherein the baffle is coupled to the second section of the housing with the at least one recess open toward the diaphragm, and the at least one fin is movable within the at least one recess in response to external pressure on the contact surface of the diaphragm.
