摘要： According to the present invention, a cooling apparatus using boiling and condensing refrigerant, includes a refrigerant tank placed in a sealed space formed in a casing, and a radiator placed in a non-sealed space in the casing. Refrigerant is sealed in the refrigerant tank. The refrigerant tank has a metal base plate joined to one wall surface of an extrusion member constituting the refrigerant tank. A base plate has a first heating element having a high heating density fastened thereto with bolts. To another wall surface of the extrusion member is joined a heat-receiving fin which transmits the heat received from the air in the sealed space to the refrigerant in the refrigerant tank and is covered with a cover which also serves as a passage for the air from a fan. In the sealed space where the refrigerant tank is placed, plural second heating elements having low heating densities are placed without being directly attached thereto. In this way, it is possible to cool at least two heating elements having different heating densities and to reduce the size of the apparatus as well as the manufacturing cost.

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： According to the present invention, a cooling apparatus using boiling and condensing refrigerant, includes a fluid separating plate for separating a high-temperature fluid from a low-temperature fluid, a refrigerant tank disposed on the side of the high-temperature fluid from the fluid separating plate, a refrigerant sealed into the refrigerant tank, a pair of communication pipes, one end of which is communicated with the refrigerant tank hermetically, a condensing portion communicated with the other end of the communication pipes and disposed on the side of the low-temperature fluid from the fluid separating plate, and a heat insulating material as a high-temperature portion-side heat insulating material coated on the outer periphery of the high-temperature-side communication pipe. In this way, it is possible to suppress a heat conduction from a high-temperature portion (high-temperature air) to the high-temperature-side communication pipe. As a result, it is possible to prevent the descending refrigerant which has been condensed and liquefied in the radiator from receiving heat from the high-temperature portion through the high-temperature-side communication pipe to receive an ascending force in the high-temperature-side communication pipe.

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 heat exchanger is constructed by laminating rectangular shaped partition walls and corrugated fins alternately. A first fluid passage through which a high temperature internal air and a second fluid passage through which the low temperature external air flows are formed into rectangular parallelopipe-shape the longitudinal direction of which is upper and lower direction. The corrugated fin is disposed inside the fluid passage to incline frontwardly. A first fluid inlet is provided at an upper position and a first fluid outlet is provided at a lower position of the first fluid passage. While, a second fluid inlet is provided at a lower position and a second fluid outlet is provided at an upper position of the second fluid passage. That is, the first fluid and the second fluid flow in an opposite direction to each other. Therefore, because the fluid introduction area of the corrugated fin is large in comparison with that in a conventional counter-flow type heat exchanger, the pressure loss of the fluid is suppressed, and the corrugated fin does not tend to be choked with a dust or the like.

摘要： A cooling device includes: a partition plate for partitioning an interior of a case into a first fluid passage through which first fluid having a high temperature flows and a second fluid passage through which second fluid having a low temperature flows; a heat receiving portion disposed in the first fluid passage; a heat radiating portion disposed in the second fluid passage; and a connection pipe for communicating the heat receiving portion and the heat radiating portion. The heat radiating portion is disposed at an upper side of the heat receiving portion in such a manner that the second fluid from a front side of the heat radiating portion flows into a rear side of the heat radiating portion through a pipe space between the heat radiating portion and the heat receiving portion, and further passes through the heat radiating portion from the rear side toward the front side of the heat radiating portion. Thus, the cooling device has a small size while improving the cooling capacity of the cooling device.
