TECHNICAL FIELD

The present disclosure relates to a connector assembly, and particularly relates to a connector assembly having a liquid cooling tray.

BACKGROUND

U.S. Pat. No. 7,625,223 B1 discloses a receptacle assembly which includes a guide frame, a heat sink, and a conductive gasket. The guide frame includes a top wall and defines an internal cavity configured to receive a mating connector. The top wall defines an opening which is communicated with the internal chamber. The heat sink is held in the internal cavity such that an upper portion of the heat sink passes through the opening and a lower portion of the heat sink is engaged with the mating connector when the mating connector is inserted into the internal cavity. The conductive gasket is held between the guide frame and the heat sink. The heat sink includes an engagement portion, when the mating connector is inserted into the internal cavity, the engagement portion provides a thermally conductive pathway for the mating connector. The conductive gasket is configured to be compressed between the guide frame and the heat sink so that the conductive gasket provides a conductive path between the heat sink and the guide frame. However, the heat sink disclosed in this prior art is generally a metal heat sink with heat dissipation fins, a principle thereof is that heat is brought out by an air flow between the heat dissipation fins, heat dissipation performance of the heat sink is slightly insufficient when the heat sink is used in a connector assembly which has a higher transmission speed and generates more heat.

Chinese invention patent application publication No. CN110139534A (corresponding to United States patent application publication No. US2019/0246523A1) discloses a cooling device which includes a manifold and a plurality of pedestals. The manifold includes a housing that encloses an interior cavity, the interior cavity is used to receive a cooling fluid and circulate the cooling fluid. Each of the pedestals is individually and flexibly coupled to the housing of the manifold via a bellows which is used to seal and is ring-shaped. Each pedestal is configured to extend outwardly from a bottom surface of the housing when a fluid pressure is present within the interior cavity. However, the bellows in this prior art only provides a flexible connection between the pedestal and the manifold, only there is a fluid pressure in the inner cavity of the manifold can the pedestal have a sufficient energy to extend outwardly from the bottom surface of the housing of the manifold. Firstly, the bellows as a connection sealing member between the pedestal and the manifold is not only complex in structure but also difficult to manufacture; secondly, because only the pedestal needs to use a fluid pressure can the pedestal extend outwardly, when the fluid pressure is insufficient or unstable, it is prone to cause a protruding amount of the pedestal which protrudes from the manifold insufficient, which results in a pressure of the pedestal contacting an electrical module is insufficient or even the pedestal cannot contact the electrical module, in turn heat dissipation efficiency is lowered. In addition, when a plurality of electrical modules need to contact the individual pedestals on the manifold at the same time, with respect to a case that the protruding amount of each pedestal which protrudes from the manifold is insufficient and an elastic restoring force of each pedestal relative to the manifold is insufficient, due to tolerances of individual electrical modules, the individual electrical modules cannot contact the respective pedestals on the manifold at the same time.
