Abstract

PURPOSE:To prevent a photoelectric converter set up in a heat insulating case from the transmission of oscillation of a refrigerating machine and to improve the performance of the photoelectric converter, by putting bellow coupling means for the removal of oscillation between the heat insulating case and the gas circulation type refrigerating machine. CONSTITUTION:A cooling lod 11 of a herium gas circulation type refrigerating machine 10 is coupled with a band-like heat conductor to which a heat conductive copper foil e.g. is laminated at the back of a cooling board 5 in an internal pipe 3. In addition to an ordinary coupling structure welded with pressure through a cleaning head 12 together with springs, the refrigerating machine 10 is fitted to a sealing flange part 13 of the heat insulating case 1 with screws through the expansible bellow coupling means 14 for suppressing oscillation. Consequently, the photoelectric converter set up in the heat insulating case is prevented from the transmission of oscillation of the refrigerating machine 10 and the performance of the photoelectric converter can be improved.

('b) Background of the technology Photoelectric conversion devices that utilize the photoelectric effect of semiconductors, especially infrared detection devices used in the long wavelength infrared region, do not work well unless the infrared detection element is cooled to a temperature significantly lower than room temperature. Generally, an insulated container with a dewar structure consisting of an outer tube and an inner tube is used, and an infrared detection element is installed on the vacuum side wall of the inner tube, which faces a transparent window provided in a part of the outer tube. The sensing element is cooled down to a predetermined low operating temperature by storing a liquid refrigerant such as liquid nitrogen in the inner tube, or by inserting a cooling rod of a helium gas circulation type refrigerator. A configuration is in place to make it work.

U. Prior Art and Problems By the way, among the cooling-type infrared detection devices configured as described above, infrared detection devices that use a helium gas circulation refrigerator to operate the detection element at a low temperature require replenishment of liquid refrigerant during operation. While it has the excellent advantage of being able to maintain the sensing element at a required low temperature and operate it continuously for a long period of time without having to do so, it also compresses and adiabatically expands the He gas in the refrigerator to generate cold. The minute vibrations generated in the drive section are directly transmitted to the infrared sensing element through the heat insulating container, resulting in noise, which has the drawback of deteriorating the detection characteristics of the infrared sensing element.
