ABSTRACT:
A pipe for a cooling unit comprises an outer pipe, and an inner pipe shorter than the outer pipe and located at an evaporating portion in the outer pipe, a circulation gap being defined between the inner wall surface of the outer pipe and the outer wall surface of the inner pipe and leading from one end to the other end of the inner pipe, whereby working liquid is permitted to boil up continuously and stably in the evaporating portion even uder a low temperature flow of working liquid. Also, a cooling unit comprises a plurality of pipes for the cooling unit as noted above, which are arranged as standing side by side vertically or obliquely, and upper and lower header pipes communicating to the upper and lower ends of these pipes, respectively, whereby the thermal conductivity is increased even under the low temperature flow of working liquid, and a plurality of portions to be individually cooled are permitted to be cooled down in case of employment of a heat pipe cooling system for cooling, even if the levels of these portions differ from each other. An individual cooling system comprises a plurality of cooling units as noted above to circulate the refrigerant, whereby a plurality of partitioned spaces are permitted to be cooled down individually and efficiently.
