Provided are a cage assembly and a receptacle assembly that can efficiently cool a heat sink. An embodiment includes: a cage 100 configured to house an optical module 310; and a heat sink 50 configured to thermally contact with the optical module 310, the cage 100 has a port wall 110 defining a port Sp in which the optical module 310 is housed, a first adjacent wall 120 defining a first adjacent space S1 that is adjacent to the port Sp in the second direction, and a second adjacent wall 130 defining a second adjacent space S2 that is adjacent to the port Sp in the third direction and in which the optical module 310 is not housed, and the heat sink 50 is housed in the first adjacent space S1.

A heat exchanger system and method includes a securing frame, a heat transfer core having heat transfer panels removably secured to the securing frame, the heat transfer panels optionally including a plurality of segment modules coupled together, and one or more filter screens removably secured to the securing frame at one or both of an inlet end or an outlet end. The heat transfer core is disposed between the inlet end and the outlet end.

The present disclosure provides a heat exchanger. The heat exchanger includes a first heat exchange body and a second heat exchange body which are configured to transfer heat, the first heat exchange body and the second heat exchange body are connected with each other, and a connecting gap being provided between the first heat exchange body and the second heat exchange body; and a first baffle and a second baffle, the first baffle and the second baffle are respectively located on two opposite sides of the first heat exchange body and the second heat exchange body, the first baffle and the second baffle being oppositely arranged, and the connecting gap being located between the first baffle and the second baffle.

The present invention concerns a heat exchange system including at least one support, a first heat exchanger and a second heat exchanger, each of the first heat exchanger and the second heat exchanger being fixed to the support via a fixing element including at least one tongue. The first heat exchanger includes a first tongue and the second heat exchanger includes a second tongue, the first tongue and the second tongue extending facing one another, each of the first tongue and the second tongue engaging with a common fixing tab of the support.
