COOLER, X-RAY COMPUTED TOMOGRAPHY APPARATUS, AND MAINTENANCE METHOD OF X-RAY COMPUTED TOMOGRAPHY APPARATUS

摘要

According to one embodiment, a cooler includes a casing, a radiator unit which is installed in a circulation path, where a coolant is circulated, and is configured to externally discharge heat of the coolant, and a fan unit housed in the casing to generate an air flow passing through the radiator unit. A windward side of the radiator unit is exposed to an outer side of the casing.

主权项

1. An X-ray computed tomography apparatus comprising:
an X-ray tube device comprising a housing, and an X-ray tube housed in the housing, the X-ray tube including a cathode configured to discharge an electron beam, an anode target configured to discharge an X-ray by receiving the electron beam, and a vacuum envelope which stores the cathode and the anode target; a coolant where at least a part of heat generated in the X-ray tube is transferred; a circulation path where the coolant is circulated; a circulation pump installed in the circulation path to circulate the coolant; a radiator unit installed in the circulation path to externally discharge the heat of the coolant; a fan unit configured to generate an air flow passing through the radiator unit; an X-ray detector configured to detect the X-ray; and a rotary gantry frame including a ring-shaped frame portion rotating with respect to a rotation axis, the X-ray tube device, the circulation pump, the radiator unit, the fan unit, and the X-ray detector being installed in the rotary gantry frame, wherein a windward side of the radiator unit is exposed in an inner wall side space of the frame portion.
