A thermal energy transfer device attached to an object to dissipate thermal energy from the object is described. In one aspect, the device includes a non-metal base plate and first and second non-metal plate structures. The base plate includes at least one groove on one of its primary surfaces. An edge of the first plate structure is received in a first groove of the at least one groove of the base plate. An edge of the second plate structure is received in a second groove of the at least one groove of the base plate.

A fluidic thermal exchange element adapted to cool a heat generating component includes a thermal conductive element having a first surface that thermally contacts the heat generating component and a second surface having fins in a cell configuration. A cover is fluidically sealed relative to the thermal conductive element to form a cavity and has first and second fluid access points arranged relative to the fins such that cooled fluid flowing from the first access point to the second access point in the cavity interacts with the fins and acquires thermal energy therefrom to create heated fluid at the second access point. A modular radiator receives the heated fluid from the second access point and cools the fluid to create the cooled fluid for recirculation to the first access point. The modular radiator has a plurality of fluid-fluid thermal coupling elements (FFTCEs), each including first and second fluid thermal interface elements disposed in a frame. A plurality of the FFTCEs are stacked upon each other between top and bottom plates to mechanically restrain the FFTCEs, and the top plate comprises a first fluid access port for accepting the heated fluid and directing the heated fluid to flow through access channels in the respective frames of the FFTCEs to provide heat exchange with the respective FFTCEs to provide the cooled fluid at a second fluid access port that is connected to the first fluid access point.

A solar energy receiver can include a heat sink configured to cool or otherwise dissipate heat. The heat sink can include a plurality of fin members, each having bases that are generally aligned with each other. The bases of the fin members can be connected to one another with connection devices that are spaced away from the bases, so as to improve thermal conductivity performance characteristics.

A heat sink includes a heat sink base, a first fin, and a second fin. The spacing between the base and the first fin and the second fin, restively, may be adjusted by rotating a threaded rod. The threaded rod includes a first threaded knurl that is engaged with the first fin and a second threaded knurl that is engaged with the second fin. The thread pitch of the first threaded knurl and the second threaded knurl may differ. For example, the pitch of the first threaded knurl may be smaller than the pitch of the second threaded knurl if the first fin is located nearest the heat sink base relative to the second fin. The spacing of the heat sink fins may be adjusted based upon the current operating conditions of the electronic device to maintain an optimal temperature of a heat generating device during device operation.
