1. An electrical device comprising:
a device housing having a frame defining a cavity, the device housing including a front, a rear, a first side between the front and the rear and a second side between the front and the rear, the rear of the device housing configured to be plugged into an equipment rack in a plugging direction;
an electrical component received in the cavity; and
a heat exchange assembly received in the cavity, the heat exchange assembly including a component heat exchanger having a component thermal interface thermally coupled to the electrical component, the heat exchange assembly including a device heat exchanger extending along the first side, the device heat exchanger having a separable thermal interface extending to an exterior of the frame of the device housing to interface with an external heat exchanger in a sliding mating direction parallel to the plugging direction, the separable thermal interface being a compressible interface with the external heat exchanger, the separable thermal interface being compressible in a direction perpendicular to the plugging direction, the separable thermal interface oriented parallel to the first side, the device heat exchanger transferring heat to the external heat exchanger across the separable thermal interface, the separable thermal interface being a dry interface with the external heat exchanger, the heat exchange assembly including a thermal conduit between the component heat exchanger and the device heat exchanger, the thermal conduit including a liquid pipe circulating heat between the component heat exchanger and the device heat exchanger, wherein the liquid pipe is spaced apart from the separable thermal interface such that the separable thermal interface is a dry interface with the external heat exchanger.
