Abstract: A heat distribution structure, a method for manufacturing the same and a heat-dissipation module incorporating the same are disclosed. The heat distribution structure includes a first cap with a first grove and a second cap with a second groove and a support body interposed between the first cap and the second cap, wherein microstructures are formed at the bottoms of the first groove and the second groove and through holes are formed in the support body. The support body is interposed between the first and second caps, such that a cavity is formed by the first cap, the support body and the second cap. A working fluid is contained in the cavity that flows therein through capillary action provided by the microstructures of the first and second grooves and the through holes in the support body, thus evenly distributing heat in the heat distribution structure.

Abstract: A heat-dissipating device and a heat-dissipating system are provided. The heat-dissipating system includes a driver, a heat-exchanger and a heat-dissipating device. The heat-exchanger is communicated to the driver and includes a body, a hydrophobic membrane and a cover. The body has an inlet, an outlet and a channel. Both ends of the channel exposed on a body's surface are respectively communicated to the inlet and the outlet, the inlet and outlet are communicated respectively to the driver and heat-exchanger.

The two-phase circulation of the vapor-condensate in the heat dissipation system, especially in the heat dissipation system with a plate evaporator, can effectively increase the heat conductivity of the plate heat source such as electronic chip. The design and composition of the wick structures are enormously decreased the turning-on temperature of the heat dissipation system and maintained the heat dissipation system in the balancing state under the low heat source power.

Abstract: A loop type heat dissipating apparatus with a sprayer for transferring heat between a heat source and a heat sink includes an evaporator, a condenser, and a working fluid. The evaporator contacts the heat source and includes a first chamber, a second chamber, and a sprayer disposed between therebetween. The condenser contacts the heat sink and includes a third chamber communicating with the second chamber and a wick structure disposed on one side of the third chamber. The working fluid fills the loop type heat dissipating apparatus and is turned into microdroplets via a sprayer. The sprayer impinges the microdroplets into the second chamber where the microdroplets are then evaporated by the heat source before proceeding to the third chamber for condensation, liquefaction and adhering to the wick structure. Eventually, the working fluid flows back to the first chamber under a pumping force actuated by the sprayer and completes the cycle.
