Abstract: A heat sink includes a fluid channel and a cooling wall in contact with coolant flowing in the fluid channel. The channel is configured to vary the velocity of coolant along the length of the fluid channel to vary the coolant's heat transfer coefficient and thereby compensate for the coolant's temperature rise along the length of the fluid channel. The result is a heat sink that is isothermal along its length.

Abstract: A heat spreader comprising a casing, a micro-structure layer, a support device, and a working fluid is provided. The casing has an inner surface and is defined by a sealed chamber where the working fluid circulates therein. The micro-structure layer is formed on the inner surface of the casing, wherein the micro-structure layer comprises a first structure layer which is formed by the first metallic mesh. Specifically, the first metallic mesh forms the first structure layer on the inner surface through diffusion bonding so that the working fluid can circulate within the micro-structure layer by capillary action. In addition, the support device is disposed in the sealed chamber for supporting the casing. Thus, a heat spreader with a composite micro-structure can not only enhance the capillarity but also reduce the flowing resistance during operation.

Abstract: A substrate formed of a suitable conductive-heat-transfer material is formed with small channels of a size selected to provide surface tension forces dominating a motion of a liquid-phase working fluid. A space above the channels of the substrate provides comparatively unobstructed space for the transport motion of a vapor phase of the working fluid effecting a heat-pipe effect in a multi-dimensional device. Channels may typically be formed in an orthogonal grid providing capillary return of liquids from a comparatively cooler condensation region to a comparatively warmer evaporation region, without any wicks other that the adhesion of the liquid phase working fluid to the vertices of the channels. Interference between the boundary layers of the liquid phase and the vapor phase of the working fluid are minimized by the depth of the channels, and the pedestals formed by the channel walls.
