A variable fin stack for cooling components in a chassis of a portable information handling system. The variable fin stack comprises a first array of fins coupled to a first conduit and a second array of fins coupled to a second conduit. When the chassis is in a compact configuration for use in a mobile mode, fins in the second array of fins are positioned between fins in the first array of fins and the chassis maintains a form factor. When the chassis is in an expanded configuration for use in a workstation mode, the second array of fins is withdrawn from the first array of fins and the increased surface area provides increased cooling of components operating at higher power levels.

Apparatuses, systems, and techniques to cool computer processors. In at least one embodiment, a system comprises one or more processors and a heatsink connected by a flexible heat conduit to the one or more processors, and a position of the heatsink is adjustable.

A thermal ground plane comprises top and bottom layers that are substantially impervious to fluid and together defining an inner space, a vapour transport mesh layer having a relatively coarse mesh structure and located within said space, and at least one liquid transport mesh layer having a relatively fine mesh structure and located between said vapour transport mesh layer and one of said top and bottom layers, the two said mesh layers being in contact with one another across substantially their entire planar extents. The top and bottom layers are sealed with a substantially fluid tight seal, and said inner space contains a liquid and is partially evacuated.

A heat dissipation unit with floating section includes an upper plate and a lower plate, which are closed together to define a chamber in between them, and the chamber has a working fluid filled therein. The upper and the lower plate respectively include a front section, a read section, and a middle section located between the front and the rear section. The front section and the rear section of one or both of the upper and the lower plate have a plate thickness larger than that of the middle section, such that the middle sections form flexible floating sections that allow for a floating adjustment thereat, making the front and the rear sections of the heat dissipation unit to be located at two positions having a height difference between them.

A device in a utility distribution system may comprise a housing, a heat source, a first heat sink, a second heat sink, a heat pipe, and a flexible directional thermal interface material (“DTIM”) with a high-conductivity orientation. The first heat sink may be thermally coupled to the heat source. The second heat sink may be attached to the first heat sink, and the flexible DTIM and the heat pipe may be arranged between the first and second heat sinks. The flexible DTIM may be thermally coupled with the first heat sink and the heat pipe. The heat pipe may be capable of movements with respect to the flexible DTIM. During the movements, the heat pipe may maintain the thermal coupling with the flexible DTIM, such that heat present in the first heat sink may be transferred to the heat pipe via the high-conductivity orientation of the flexible DTIM.

A flexible vapor chamber includes a first flexible casing, a second flexible casing, a plurality of capillary strips and a plurality of inner capillary layers. The capillary strips are installed between the first flexible casing and the second flexible casing, and the inner capillary layers are arranged between the first flexible casing and the second flexible casing, and the capillary strips.

A hetero-material floating heat pipe structure includes a main body and a multi-segment floating adjustment unit. The main body has a front end, a rear end and a flexible section disposed between the front end and the rear end. The flexible section has flexibility, whereby the main body is flexible. The multi-segment floating adjustment unit is disposed on an outer surface of the flexible section for restricting and protecting the flexible section. The multi-segment floating adjustment unit includes multiple adjustment members, which are pivotally connected with each other and stringed to form the multi-segment floating adjustment unit. Each of two ends of each adjustment member has a pivoted section. By means of the pivoted sections, the adjustment members are pivotally connected with each other and can be swung and bent by the same angle or by different angles to adjust the arrangement of the multi-segment floating adjustment unit.

A multi-angle adjustable and transformable heat pipe includes a sealed case body. A working fluid is filled in the sealed case body. At least one capillary structure is disposed on an inner wall of the sealed case body. The sealed case body has a front section, a rear section and a transformable flexible middle section. The middle section is positioned between the front section and the rear section in connection therewith. The middle section is composed of multiple support sections and multiple knot sections. The support sections and the knot sections are alternately arranged. Two sides of each knot section are respectively connected with adjacent support sections, whereby the support sections can be adjusted by the same angle or different angles with the knot sections serving as fulcrums so that the heat pipe can be multi-angle adjusted and transformed and located.
