Title
(EN) ADDITIVES TO FREEZE POINT SUPPRESSANTS AND TO HEAT TRANSFER FLUIDS IN HEAT EXCHANGERS
(FR) ADDITIFS POUR ANTIGEL ET FLUIDES DE TRANSFERT THERMIQUE DANS DES ECHANGEURS THERMIQUES
Abstract
(EN) A product (figure) which is mixed with water based heat transfer fluids to provide a heat exchange fluid in which some or all of the additives used with standard freeze temperature depressants, such as ethylene glycol or propylene glycol, are no longer required. In addition, for non-aqueous coolants or for mixtures of water with either ethylene glycol or propylene glycol, the viscosity of the resultant mixtures is significantly decreased by addition of this invention.
(FR) L'invention concerne un produit (figure) que l'on mélange à des fluides de transfert thermique à base d'eau afin d'obtenir un fluide d'échange thermique dans lequel certains des additifs ou tous les additifs utilisés avec des antigels classiques, tels que l'éthylène glycol ou le propylène glycol, ne sont plus nécessaires. De plus, pour des liquides de refroidissement non aqueux ou pour des mélanges d'eau avec soit de l'éthylène glycol, soit du propylène glycol, la viscosité des mélanges obtenus est sensiblement réduite par addition du produit de cette invention.
