Abstract: A heat transfer device includes a base that is configured to move relative to a support along a first direction and to receive a heat transfer fluid from the support via a fluid coupling. The fluid coupling is configured to expand and contract along the first direction to accommodate movement of the base relative to the support. The base may include a contact surface to engage and transfer heat with respect to a heat generating device, such as a device including optics modules requiring cooling. Heat received from the heat generating device may be transferred to the heat transfer fluid in a chamber of the base.

Abstract: A heat transfer arrangement for use with an immersion cooling system. A support is configured to contact a heat transfer device such as a vapor chamber or spreader plate to stiffen the heat transfer device and urge the heat transfer device into contact with a heat generating device. The support includes an arm that has a first portion that extends toward a central area of the heat transfer device over and out of contact with the heat transfer device and a second portion that contacts the heat transfer device within the central area. The arm can avoid contact with the heat transfer device, including surfaces having a boiling enhancement coating configured to transfer heat to a cooling liquid.
