The electronic equipment null setting point which has fitting fluid leak prevention structure and fitting

摘要

PROBLEM TO BE SOLVED: To prevent liquid leakage from a joint part when liquid leakage of working fluid made of antifreeze is sensed, with respect to a structure for preventing liquid leakage of a pipe joint.;SOLUTION: In a liquid cooling tube, mixture of an antifreeze component the freezing point of which is 0°C or lower and water is used as working liquid. An outer periphery of the joint part of the liquid cooling tube is serially coated with a first hygroscopic swelling material, a film element which selectively permeates water, and a second hygroscopic swelling material.;COPYRIGHT: (C)2011,JPO&INPIT
