Abstract: A memory cooler includes a unitary thermal transfer device and a pair of endcaps. The unitary thermal transfer device includes heat transfer tubes, a first end block, a second end block, an inlet chamber, an outlet chamber, an inlet, and an outlet. The first and second end blocks are structurally integrated with each of the heat transfer tubes. The inlet and outlet chambers are partially defined by either the first end block or the second end block. Each of the inlet and outlet chambers are fluidly coupled with the respective liquid flow channel of the at least one heat transfer tube. The respective flow channels to which the inlet and outlet chambers are coupled may be the same or different to define either a direct or a serpentine flow path. Each endcap is affixed to a respective one of the first end block and the second end block to define, in conjunction with the first end block and second end block, the inlet chamber and the outlet chamber.

Abstract: Example implementations relate to an electronic system providing thermal management of a removable device when connected to a host device of the electronic system including a receptacle, and a heat transfer device having first and second portions. The host device has a cooling component. The removable device having a heat spreader, is detachably coupled to the host device. The receptacle having spring fingers, is coupled to one of the cooling component or the heat spreader. The first portion is coupled to one of the cooling component or the heat spreader, and the second portion is protruded outwards. When the removable device is connected to the host device, the second portion extends through the receptacle such that the spring fingers establish direct thermal interface with the second portion to allow waste-heat to transfer between the heat transfer device and one of the cooling component or the heat spreader via the receptacle.

Abstract: A thin, single-layer thermally conductive jacket surrounds a PCA. One or more living springs integrated in the jacket exert compressive force on PCA components where cooling is desired. The compressive force creates and maintains a thermal contact though which heat is conducted out of the PCA components and into the jacket. The jacket conducts the heat (either directly or indirectly) to a liquid-cooled cold plate configured as a cooling frame surrounding one or more of the jacketed PCAs. The jacket, optionally through intermediate thermal transfer devices such as heat spreaders or heat pipes, transfers heat from components on the PCA to the cooling frame. Liquid flowing through the cooling frame's internal channels convects the heat out of the electronic device. Turbulence encouraged by turbulence enhancing artifacts including bends and shape-changes along the internal channels increases the efficiency of the convection.
