HIGH PRESSURE-RESISTANT COOLING CONTAINER FOR SENSOR, AND SUBSURFACE SURVEY DEVICE

摘要

PROBLEM TO BE SOLVED: To cool SQUID continuously to a stabilized operation temperature for long hours under a high pressure exceeding 1.0 MPa, concerning a high pressure-resistant cooling container for a sensor and a subsurface survey device.SOLUTION: A high pressure-resistant cooling container includes a pressure-resistant sealed container having pressure-resistant performance of 1.0 MPa or higher, a phase change coolant heat insulation container stored in the pressure-resistant sealed container, and a tube for phase change coolant release having pressure-resistant performance of 1.0 MPa or higher connected to the pressure-resistant sealed container.
