Thermosyphon and method of manufacturing the same

Abstract

A thermosyphon formed in a simple structure, enabling an increase in heat transfer efficiency for transferring heat from the thermosyphon to the outside, and manufacturable at low cost and a method of manufacturing the thermosyphon. The double tube type thermosyphon is formed in a single and constant outside diameter size of cylindrical shape having an outer tube (10) and plug bodies (14). The outer tube (10) and the plug bodies (14) are formed in the constant outside diameter (K) size so as to come into contact simultaneously with one plane put on the upper outer surface thereof. Thus, for example, when the syphon is installed under a floor, the syphon is continuously fitted to an upper heat transfer plate in the longitudinal direction to reduce heat transfer loss and increase the heat transfer efficiency. Also, the yielding of material can be increased by reducing cut-out portions.

Description

technical field [0001] The present invention relates to a thermosiphon device and a manufacturing method thereof, in particular to a double-tube type thermosiphon device and a manufacturing method thereof, in which an inner pipe used for heat source fluid circulation is penetrated in an outer pipe serving as a main pipe. Background technique [0002] For heat exchange equipment such as heat pumps, which have the characteristic that the smaller the temperature difference between the heat exchange fluids, the lower the heat exchange efficiency, recently, thermosiphon devices that can transfer a large amount of heat with a small temperature difference by using condensation and evaporation phase changes are gradually being developed. Practical. Among them, the inner tube for the circulation of the heat source fluid is passed through the outer tube, for example, a structure in which cold and warm heat is transferred horizontally is excellent in practicality and attracts attention...
