An apparatus for dissipating heat from a photonic transceiver module. The apparatus includes a top-plate member disposed in a length direction of a package for the photonic transceiver module. The apparatus further includes multiple fins formed on the top-plate member along the length direction from a backend position to a frontend position except at least one fin with a shorter length, forming an elongated void from the backend position to one backend of the at least one fin. Additionally, the apparatus includes a cover member disposed over the multiple fins with a horizontal sheet, two vertical side sheets, and a flange bent vertically from a middle portion of backend of the horizontal sheet. Furthermore, the apparatus includes a spring loaded in the elongated void between the flange and the one backend of the at least one fin to minimize an air gap at the backend of the horizontal sheet.

A heat transfer assembly includes a first plate, a second plate, and an engaging unit. The first plate has a first side and a second side, and the second plate has a third side and a fourth side. The third side is attached to the first side, which defines a sealed chamber between the first and second plates. The fourth side has an accommodating portion that is in thermal contact with at least a heat source. The engaging unit is disposed adjacent to the accommodating portion, and engaged with the heat source, thereby allowing the heat transfer assembly to be in direct contact with the heat source. Therefore, a lower thermal resistance can be achieved by the direct contact, and no penetration to the heat transfer assembly prevents the assembly from vacuum leaks.
