[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a temperature adjusting device.

[0002]

[Prior art]

 In all technical fields, such as chemical reaction devices, chemical analysis devices, physical property measuring devices, and physical property converting devices, temperature control devices that perform heating, cooling, and heat retention are widely used as indispensable devices. . In particular, physical property converters require highly accurate and wide-range temperature adjustments.In particular, in Raman laser devices that convert the wavelength of laser light, the gas inside the converter and other devices must be kept at a specified low temperature. It is an important issue to maintain.

As shown in FIG. 2, which shows an example of a longitudinal side view of an example in which this temperature adjusting device is applied to a cooling device of a Raman laser device, this converter is provided on the outer peripheral surface of a converter 11 for performing wavelength conversion of laser light. A cooler 12, which holds 11 in a cold state, is mounted so as to surround the converter 11. A refrigerant supply port 13 for supplying a refrigerant 21, such as liquid nitrogen, which exhibits a cooling effect by the transfer of heat energy accompanying a phase change, and a refrigerant 21 having a phase change are discharged to the upper right side in the figure of the cooler 12. The refrigerant discharge ports 14 are provided adjacent to each other. A heat insulating chamber 15 having a vacuum inside is provided on the outer peripheral surface of the cooler 12 so as to surround the cooler 12.

Therefore, when the converter 11 is cooled, the refrigerant 21 is appropriately supplied from the refrigerant supply port 13 into the cooler 12. Then, the converter 11 is cooled to near the boiling point temperature of the refrigerant 21 by the heat of vaporization of the refrigerant 21. The refrigerant 21 vaporized at this time is discharged through the refrigerant outlet 14 to the outside of the cooler 12.

The temperature adjusting device shown in FIG. 2 utilizes the cooling effect of the heat of vaporization when the refrigerant 21 changes its phase from liquid to gas. In addition to the above, a method of using a fluid such as a liquid or a gas as a refrigerant within a temperature range in which no phase change is well known. This circulates these refrigerants in the cooler 12 so as to make efficient contact with the outer wall surface of the converter 11, and conducts heat transfer of the converter 11 to these refrigerants to cool the converter 11. It does.

FIG. 3 shows a concept of a vertical cross section which is an example of this case. Here, the same parts as those in the previous example are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 3, in the figure of the cooler 12, a refrigerant supply port 13 is provided on the lower left side, and a refrigerant discharge port 14 is provided on the upper right side. A partition plate 16 that circulates the liquid refrigerant 22 in the cooler 12 is spirally attached to the outer peripheral surface of the converter 11 inside the cooler 12. The coolant supply port 13 and the coolant discharge port 14 are connected to a supply unit and a recovery unit (not shown) for cooling, supplying and recovering the coolant 22, respectively.

Therefore, when cooling the converter 11, the refrigerant 22 cooled to a required temperature is supplied from the refrigerant supply port 13 into the cooler 12 by a refrigerant cooler (not shown). Then, the refrigerant 22 efficiently circulates on the outer wall surface of the converter 11 along the partition plate 16 and cools the converter 11 to a target temperature by the transfer of heat energy. Then, the circulated refrigerant 22 is collected from the refrigerant discharge port 14 into the unillustrated refrigerant chiller, cooled again, and supplied into the cooler 12.

[0009]

[Problems to be solved by the device]

 In the case of using the phase change of the refrigerant, the boiling point is determined depending on the type used as the refrigerant 21, so even if the converter 11 is cooled to an arbitrary temperature, it is very difficult to realize this cooling temperature. is there.

On the other hand, in the method not involving the phase change of the refrigerant, it is possible to easily realize an arbitrary cooling temperature by adjusting the temperature of the refrigerant 22. However, in the conventional device, the partition plate 16 must be mounted on the outer wall surface of the converter 11 so as to efficiently circulate and contact the refrigerant 22 to enhance the effect of conduction transfer of heat energy. The installation of the partition plate 16 requires a great deal of labor for manufacturing the device, which causes a significant cost increase.
