Heat Dissipation Assembly, Connector Assembly and Shielding Shell

A connector assembly, comprising:

• a connector, including:
• a shielding shell having a top wall and a bottom wall that are opposite in a height direction, a front port and a rear wall that are opposite in a longitudinal direction, and a pair of side walls that are opposite in a transverse direction, an opening is formed in the top wall of the shielding shell, a plurality of locking spring pieces are respectively formed on the pair of side walls of the shielding shell;
• and
• a heat dissipation assembly installed on a top of the shielding shell, the heat dissipation assembly includes a liquid-cooling module having a liquid-cooling plate, a bottom surface of the liquid-cooling plate has a locking structure, and an air-cooling module including a plurality of heat dissipation fins, a top surface of each of the plurality of heat dissipation fins is welded to the bottom surface of the liquid-cooling plate, a bottom of the air-cooling module protrudes into the shielding shell through the opening in the top wall to make thermal contact with a mating connector inserted into the shielding shell, the locking spring pieces engage with the locking structure on the liquid-cooling plate to lock the heat dissipation assembly to the shielding shell.
