1. An apparatus, comprising:
a printed circuit board;
a first cover plate; and
a second cover plate, wherein the first cover plate is hermetically connected to the second cover plate, wherein:
the first cover plate defines a first plurality of grooves, and a supporting portion is disposed between two adjacent grooves of the first plurality of grooves,
each groove of the first plurality of grooves includes a liquid circulation channel and a vapor circulation channel, each liquid circulation channel is filled with a liquid working medium, and each liquid circulation channel is in communication with the corresponding vapor circulation channel in a manner that when the liquid working medium vaporizes into vapor, the vapor enters the corresponding vapor circulation channel and condenses into liquid, and the liquid enters the corresponding liquid circulation channel, and
a heat emitting element is disposed on the printed circuit board, a shielding can covers the heat emitting element, a via extends in the shielding can, a thermal interface material passes through the via and is in contact with the heat emitting element, and a middle frame is in contact with the thermal interface material.
