Definitions
- the present invention relates to an improvement in a heat exchange device.
- nitrogen, oxygen, argon, and other gases are stored in a liquefied state in an ultra-low temperature storage tank, and when used, the stored liquefied gas is guided to an evaporator and evaporated at ambient temperature or hot water. Gasification.
- the technical means of the present invention for achieving the above object includes a heat exchange container to which a heat transfer medium is supplied and discharged, and a plurality of heat exchange containers which are arranged in parallel in the heat exchange container and communicate with each other in a circumferential direction.
- a heat exchange flow path having a communication flow path that communicates a plurality of locations between these circumferential flow paths so that the positions of the inlet and the outlet in each circumferential flow path are shifted in the circumferential direction; It is provided with a supply path and a discharge path of a fluid inserted into the container and communicated with the heat exchange flow path.
- the passage means an object such as a pipe through which a fluid flows.
- the heat exchange flow path has tanks on the supply port side and the discharge port side, and the supply path and the discharge path are connected to each evening tank.
- the fluid By causing the fluid to flow in a turbulent state while repeatedly colliding with the wall surface of the heat exchange channel, the fluid is greatly affected by the temperature of the wall surface, and furthermore, the fluid flows from each communication channel in each circumferential channel. Since the sent fluid is dispersed under the same conditions, a large amount of fluid can be exchanged efficiently without narrowing down the fluid. Further, since the heat exchange channel can be configured by connecting the channels, the configuration can be simplified.
- the dry air cooled by the heat exchange flows out of the tank 21 to the tank 15 by the discharge pipe 12, and can be distributed to a desired use site by the plurality of supply pipes 16.
- the temperature can be adjusted to an appropriate temperature by mixing with room temperature air before use.
- the liquefied nitrogen deprived of the cold heat by the above heat exchange is led to the evaporator 6 by the pipe 8, and is evaporated at atmospheric temperature or hot water to become nitrogen gas.
- the nitrogen gas thus obtained can be supplied to a desired use site through the supply pipe 9.
- liquefied nitrogen is directly supplied to the evaporator 6 as in the prior art, if the liquefied nitrogen is supplied to the evaporator 6 after being used for heat exchange by the heat exchange device 2 of the embodiment of the present invention, liquefied nitrogen can be obtained. Since the temperature of the evaporator 6 has risen, the efficiency of the evaporator 6 can be improved.
- the entire vessel made of SUS was placed on a weighing scale, and the scale was measured. The decrease value was measured every 30 seconds, and the average value per minute at the same flow rate was calculated.
- the dry air cooled by the heat exchanger was put into a gas holder with a 1-inch 2-inch simplex tube, and the temperature change was measured with a digital thermometer attached to the holder.
- FIG. 5 is a graph showing the temperature of the cooling dry air discharged from the heat exchanger with respect to the elapsed time from the start of the supply of the dry air when a five-stage ring type heat exchanger is used.
- circular tubes 18, 19, 11, and 12 having a circular cross section are used for the circumferential flow path, the communication flow path, the supply path, the discharge path, and the like. You may use something.
- the circumferential flow path is not limited to an annular shape, and may be rectangular or elliptical, and the communication pipes 19 need not be arranged at equal intervals.
- the diameter of each annular tube may be different.
- the communicating pipes may be connected to, for example, every other annular pipe instead of adjacent annular pipes.
- refrigerants such as liquefied oxygen, liquefied argon, LNG, etc. can be used.
- the fluid to be used can be not only dry air but also gases such as nitrogen, oxygen, hydrogen, argon, natural gas, etc., as well as a mixed gas of liquid and gas.
- annular pipes 18 which are the circumferential flow paths may be arranged in a plurality of rows in a side-by-side state around the horizontal axis.
- present invention can be variously modified within a range without departing from the basic technical concept.
- the heat exchange container when the heat exchange container is filled with the heat transfer medium and the fluid for heat exchange is supplied to the heat exchange channel from the supply channel, the supplied fluid is supplied to the heat exchange channel.
- the fluid Flows in a circumferential flow path arranged in parallel with a plurality of flow paths, and a communication flow path connecting them, but since the positions of the inlet and the outlet in the circumferential flow path are shifted in the circumferential direction, the fluid The fluid flows in a turbulent manner while repeatedly colliding with the wall surface of the heat exchange flow path.
- the heat of the heat transfer medium can be removed or the heat transfer medium can be removed, and the fluid after the heat exchange is discharged.
- the heat can be discharged to the outside of the heat exchange container by a passage.
- the heat exchange flow path has tanks on the supply port side and the discharge port side, and by connecting the supply path and the discharge path to each tank, the fluid is temporarily stored from the supply path to the tank on the supply port side and the fluid is temporarily stored.
- the heat exchange device according to the present invention is useful as a heat exchange device for air cooling and as a heat exchange device for air conditioning having a large capacity. It is suitable for use in heat exchangers where low temperatures are required.
