Ben Welter - Thursday, January 11, 2018

U.S. patent application 20180010862 (Valeo Systemes Thermiques, Le Mesnil Saint-Denis, France):

Valeo patent drawing"The present invention relates to an encapsulated phase-change material comprising a phase-change material (3) contained within a tube (5), said tube being made of plastic and that it has a sealing weld (9) at least at one of its ends. ... The presence of sealing welds allows good sealing and also reduces the risk of leakage of phase-change material notably when the latter is in the liquid phase."
