본 발명은 냉각제 및 열 운반 액체에 적합한 내식성 부동 농축물에 관한 것으로서, 상기 농축물은 빙점 강하 액체 및 황 함유 유기 화합물, 무기 염 몰리브데이트, 무기 포스페이트 염, 및 지방족, 지환족 및 방향족 모노카본산, 디카본산 또는 트리카본산을 포함한다. 내부 연소 엔진을 냉각시키기에 적합한 수성 냉각제 조성물을 이로부터 수득할 수 있는데, 여기서, 상기 엔진의 냉각 장치는 플루오로알루미네이트 납땜 플럭스를 포함하는 납땜 방법을 사용하여 알루미늄으로부터 제조되었다. The invention relates to an anti-freeze concentrate having corrosion protection, suitable for coolants and heat carrier liquids, comprising liquids lowering the freezing point and organic compounds containing sulfur, inorganic salts molybdate, inorganic phosphate salts, inorganic phosphate salts and aliphatic, cyclo-aliphatic and aromatic mono-, di- or tri-carbonate acids. Aqueous coolant compositions can be obtained therefrom, which are suitable for cooling an internal combustion engine, the cooling device of which has been produced from aluminum by using a soldering method comprising a fluoroaluminate soldering flux.
