A bottle having substantially no strain due to fluidized orientation in the bottom portion thereof which is homogeneously and uniformly drawn, and, as a result, exhibiting improved shock resistance and buckling strength in the bottom portion, featuring excellent resistance against environmental cracking at the center in the bottom portion, without developing crazing or whitening during the preservation, and offering excellent appearance. The bottle is formed by biaxially stretch-blow-molding a thermoplastic resin, and has a mouth portion, a shoulder portion, a barrel portion and a bottom portion, said bottom portion without being substantially affected by the residual strain due to orientation by fluidization.

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.

A fuel cell system includes a fuel cell (FC stack), an inflow passage valve provided in a hydrogen inflow passage through which hydrogen is supplied to the FC stack, and a discharge passage valve provided in a hydrogen discharge passage through which hydrogen containing gas is discharged from the FC stack as exhaust gas. In the fuel cell, hydrogen is supplied to the FC stack intermittently in accordance with an amount of hydrogen consumed in the FC stack, by controlling opening and closing of the inflow passage valve and the hydrogen discharge valve.

A cooling device includes a boiling unit and a condensing unit. A diffusion plate having a plurality of holes is formed into a thin-long shape, and is disposed in an upper tank of the condensing unit at an approximate center in an up-down direction so that an inner space of the upper tank of the condensing unit is divided into upper and lower parts in the up-down direction. Each hole opened in the diffusion plate has an opening area smaller than a sectional surface area of an introduction port of a gas-refrigerant introduction pipe, opened in the upper tank of the condensing unit. Thus, gas refrigerant flowing into the upper tank of the condensing unit through the gas-refrigerant introduction pipe is diffused to all the upper part of the upper tank along the surface of the diffusion plate while passing through the holes of the diffusion plate downwardly. As a result, an entire area of the condensing unit can be effectively used, and heat-radiating performance of refrigerant in the condensing unit can be improved.

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.

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.

According to the present invention, the cooling apparatus includes a refrigerant tank to which a semiconductor device is attached, a connection chamber which is open to the central portion of the refrigerant tank on the side opposite to the side where the semiconductor device is mounted, a first tube (a first radiator) having one end in communication with the connection chamber and the other end in communication with one end of the refrigerant tank, a second tube (a second radiator) having one end in communication with the connection chamber and the other end in communication with the other end of the refrigerant tank, and refrigerant contained in the refrigerant tank. Even when the cooling apparatus is inclined, at least one of the other end of the first tube and the other end of the second tube can be immersed below the liquid level of the refrigerant so that the refrigerant can circulate within the refrigerant tank efficiently.

Cooling pipes having refrigerant sealed therein are made of flat-shaped pipes having a thin rectangular cross-section, and are disposed to pass through a through hole of a fluid separator. One side of the pipes disposed at a high temperature fluid side of the fluid separator of the cooling pipes serves as a refrigerant portion while the other side of the pipes, disposed at a low temperature fluid side of the fluid separator, serves as a condensing portion. The top and bottom of the cooling pipe communicate with each other via communicating members. In the cooling pipes, a heat receiving fin is connected to the outer wall of the refrigerant portion and a heat radiating fin is connect to the outer wall of the condensing portion. The heat receiving fin and the heat radiating fin are connected integrally with the cooling pipe by brazing.
