Title:
DEVICE TEMPERATURE ADJUSTMENT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/217919
Kind Code:
A1
Abstract:
A device temperature adjustment apparatus (1) is configured as a thermosiphon for carrying out a heat transfer by means of a phase change between a liquid phase and a gas phase of a working fluid sealed in a tubular sealed container (10) and adjusts the temperature of a subject device (BP) by the transfer of heat. The device temperature adjustment apparatus is equipped with a plurality of evaporation sections (14, 16) for absorbing heat from the subject device into the working fluid and thereby evaporating the working fluid, and at least one condensation section (12) for dissipating heat to the outside from the working fluid evaporated by the plurality of evaporation sections and thereby condensing the working fluid. The device temperature adjustment apparatus is equipped with at least one connecting tube section (20) for connecting the plurality of evaporation sections in series. When one evaporation section among adjacent evaporation sections is defined as a first evaporation section (14) and the other is defined as a second evaporation section (16), at least a portion of the first evaporation section is positioned above the second evaporation section. The connecting tube section serves as a separation acceleration structure in which the gas-liquid separation of the working fluid flowing through the connecting tube section is accelerated.
