DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an improvement in a heat exchanging apparatus.
BACKGROUND ART
In the past, nitrogen, oxygen, argon and other gases are stored in a superlow temperature storage tank in a liquefied state. When in use, the stored liquefied gas is fed to an evaporator where the gas is vaporized and gasified at an atmospheric temperature or in hot water.
However, in the past, cooling heat of the liquefied gas is not effectively utilized but is wasted. In order to effectively utilize the cooling heat to cool gases such as air, nitrogen, oxygen, argon, hydrogen, etc., or fluids such as a mixture of liquid and gas, etc., it is contemplated that a heat exchanger is intervened between a superlow temperature storage tank and an evaporator.
The conventional heat exchangers heretofore used have various configurations such as a coil type, a double tube type, a water injection type, a bushing type, a finned multitube type, etc.
However, the conventional heat exchangers as described above are poor in cooling effect because the fluid to be cooled flows through the tube regularly and is less affected by a temperature from wall surfaces of the tube. So, when being restricted as in an expansion valve at downstream in order to enhance the cooling effect, a large quantity of fluids cannot be cooled. Accordingly, there was a problem in that the conventional heat exchangers cannot be utilized in the case where a large quantity of fluids at a constant temperature need be secured.
The present invention is to overcome the problem as noted above with respect to prior art. It is an object of the present invention to provide a heat exchanging apparatus which can heat-exchange a large quantity of fluids efficiently without restricting the fluids, and accordingly, a large quantity of heat exchanging fluids at a constant pressure and at a constant temperature can be obtained and conveniently utilized, and in which the construction thereof can be simplified to thereby remove troubles and to lower the cost.
DISCLOSURE OF THE INVENTION
Technical means of the present invention for achieving the aforementioned object comprises a heat exchanging vessel to and from which a heat transfer medium is supplied and discharged; a heat exchanging flowpassage having a plurality of peripheral flowpassages arranged in parallel within said heat exchanging vessel and communicated in a peripheral direction and communicating flowpassages in which a plurality of locations between said peripheral flowpassages are communicated so that positions of an inlet and an outlet in each peripheral flowpassage are deviated in a peripheral direction; and a fluid supply path and a fluid discharge path inserted into said heat exchanging vessel and communicated with said heat exchanging flowpassage. It is to be noted that the flowpassage termed herein means an article such as a tube through which fluid flows. The same is true for claims.
Preferably, in the aforementioned technical means, the heat exchanging flowpassage has tanks on the supply port side and on the discharge port side, and the supply path and the discharge path are communicated with the tanks.
According to the present invention constructed as described above, when the heat exchanging vessel is filled with the heat transfer medium and the fluid for heat exchange is supplied from the supply path to the heat exchanging flowpassage, the thus supplied fluid in the heat exchanging flowpassage flows into the plurality of the peripheral flowpassages arranged in parallel and the communicating flowpassages for communicating them. However, since the positions of the inlet and the outlet in the peripheral flowpassages are deviated in a peripheral direction, the fluid flows as a turbulence while repetitively impinging upon the wall surfaces of the heat exchanging flowpassages, during which the fluid can carry away heat of the heat transfer medium or heat of the fluid can be carried away by the heat transfer medium, and the fluid after heat exchange can be discharged outside the heat ex
