    摘要: An IGBT module has an IGBT element. Within a refrigerant tank is sealed refrigerant. On the bottom part of the refrigerant tank is provided the IGBT module. The heat emitted from the IGBT element is absorbed by the refrigerant by the transmission of the boiling heat emitted from the IGBT element and the refrigerant is gasified by the absorbed heat. A radiation tube is communicated with the refrigerant tank at one end and blocked at the other end. Within the radiation tube is disposed corrugated inner fins, and an upper space, refrigerant passages through for guiding the refrigerant from the refrigerant tank into the upper space, and thin holes in which a liquid pooling part for returning the refrigerant from the upper space into the refrigerant tank is formed are dividingly formed respectively.

    摘要: A cooling apparatus includes a refrigerant tank having a surface to which heating devices are attached and containing liquid refrigerant which is boiled and evaporated by heat transferred from the heating devices, and a radiator for radiating the heat of the boiled and vaporized refrigerant. The radiator has an inflow return chamber provided with a small-diameter opening having a diameter smaller than that of the inflow return chamber. The liquid refrigerant of the gas-liquid mixed refrigerant is dammed by the small-diameter opening of the inflow return chamber and the dammed liquid refrigerant is returned through a return passage to the refrigerant tank. Since the liquid refrigerant contained in the gas-liquid mixed refrigerant is suppressed from flowing by means of the small-diameter opening, the gaseous refrigerant can transfer heat directly to the walls of the radiating passages, so that the deterioration of the radiating performance can be prevented.

    摘要: An object of the present invention is to provide a cooling apparatus using a boiling and condensing refrigerant which can be economically manufactured. Another object is to improve reliability of soldering. A refrigerant tank, on which hot objects to be cooled is mounted, is connected to a radiator for condensing the vaporized refrigerant through a coupler made of two plates bonded together by soldering. The coupler connecting the tank and the radiator can be made easily and economically even if it has a complex shape, because the coupler is composed of two stamped plates. To bond two plates together by soldering process, it is necessary to secure an air-tightness and a high reliability. Improved configurations of the coupler and ways of fastening the two plates effectively are provided in the present invention.

    摘要: A power pack is mounted on the side wall of a refrigerant tank in which the internal pressure is reduced and a refrigerant is held in such a way that a heat transfer panel on which a power element is mounted can contact the refrigerant. The refrigerant boiled and gasified by heat from the contact part of the heat transfer panel 19 is guided into a radiation part planted on the top of the refrigerant tank 11. The radiation part is composed of a plurality of hollow tubular bodies having flat cross sections. The plurality of radiation tubes are laid out in parallel with each other at specified intervals, the upper ends thereof being closed and the lower ends thereof being open to the inside of the refrigerant tank so that the gasified refrigerant is guided thereinto. Here, the natural convection of the air is generated in the up/downward directions by the plurality of the radiation tubes, and the effective heat radiation is achieved thereby.

    摘要: A cooling apparatus using boiling and condensing refrigerant for cooling a heat generating unit, includes a refrigerant tank having a wall surface, for containing the refrigerant therein, a heat generating unit boiling the refrigerant in the refrigerant tank by heating, and a radiator disposed in communication with the refrigerant tank for condensing and liquefying the boiling refrigerant in the tank. An interior of the refrigerant tank is partitioned into a vapor passage for leading the boiling refrigerant to the radiator, a condensed liquid passage in which the condensed and liquefied refrigerant flows downwardly, and a communication path formed at a lower side thereof for communicating between the vapor passage and the condensed liquid passage. The condensed liquid passage is defined by a part of the wall surface. Since the refrigerant liquid passage is formed by the wall surface, the heat from the refrigerant in the refrigerant tank, which is received by the condensed refrigerant having condensed and liquefied in the condensed liquid passage, is reduced.

    摘要: A cooling apparatus includes a refrigerant tank having a surface to which heating devices are attached and containing liquid refrigerant which is boiled and evaporated by heat transferred from the heating devices, and a radiator for radiating heat of the boiled and vaporized refrigerant in a radiating passage thereof. In the radiating passage, a inner fin and a projection to position and fix the inner fin are provided, and a predetermined gap is provided between the projection and a bottom surface of the radiating passage. Thus the refrigerant condensed and liquefied in the radiating passage can reach an outflow communicating portion while flowing through the fluid passage formed as the gap.
