Title:
LOOP TYPE THERMO SIPHON, STIRLING COOLING CHAMBER, AND COOLING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2005/024331
Kind Code:
A1
Abstract:
A loop type thermo siphon (100A), comprising a closed circuit having evaporators (110), a condenser (130A), feed tubes (120), and return tubes (140). The condenser (130A) further comprises an assembly having a feed tube side main tube (131), a return tube side main tube (132), and a plurality of parallel tubes. The plurality of parallel tubes form portions for condensing evaporated working fluid and comprise meandering tubes having straightforward parts vertically and horizontally stacked by multiple stages and curved parts connecting these straightforward parts to each other. The entire part of the condenser (130A) formed of the assembly is disposed aslant relative to the bottom face (301) of a casing (300) so that, toward the return tube side main tube (131), the straightforward part positioned at the lowest stage among the straightforward parts of the meandering tubes can be disposed aslant in such a direction that the distance thereof from the bottom face (301) of the casing (300) on which the loop type thermo siphon (100A) is mounted is decreased. Thus, the operational defect of the loop type thermo siphon resulting from an installation state can be reduced.
