According to one of the broader forms of the invention, a method and apparatus involve an integrated circuit that includes a heat transfer structure having a chamber that has a fluid disposed therein and that extends between a heat generating portion and a heat absorbing portion. Heat is absorbed into the fluid from the heat generating portion, and the fluid changes from a first phase to a second phase different from the first phase when the heat is absorbed. Heat is released from the fluid to the heat absorbing portion, and the fluid changes from the second phase to the first phase when the heat is released. | 06-30-2011 |
20140239487 | HEAT PIPE IN OVERMOLDED FLIP CHIP PACKAGE - The present invention is an improvement in a molded semiconductor package and the method for its manufacture. The package comprises a substrate, a semiconductor die mounted on the substrate, a molding compound encircling the die on the substrate, a lid on the molding compound, and a heat pipe extending between the semiconductor die and the lid. Preferably, the heat pipe is formed so that it encircles the die. The package is assembled by mounting the die on the substrate, applying the molding compound to the substrate while a channel is formed in the molding compound adjacent the semiconductor die, inserting a heat pipe material in the channel, and mounting the lid on the molding compound and the heat pipe material. | 08-28-2014 |
20140252590 | SEMICONDUCTOR MODULE COOLER AND SEMICONDUCTOR MODULE - A semiconductor module cooler for supplying a refrigerant from exterior into a water jacket and cooling a semiconductor device disposed on an outer surface of the cooler, includes a heat sink thermally connected to the semiconductor device; a first flow path extending from a refrigerant inlet and arranged with a guide portion having an inclined surface for guiding the refrigerant toward one side surface of the heat sink; a second flow path extending toward a refrigerant outlet and formed with a sidewall parallel to the other side surface of the heat sink; a flow velocity adjustment plate disposed in the second flow path and formed parallel to the other side surface of the heat sink at a distance therefrom; and a third flow path formed at a position communicating the first flow path and the second flow path. The heat sink is disposed in the third flow path. | 09-11-2014 |
