摘要： In order to cool an engine effectively, an engine oil temperature is detected by an oil temperature sensor. When the engine oil temperature is above a predetermined valve, the cooling fluid being introduced into the engine is divided into two streams. One stream is introduced into a cylinder head and the other stream is introduced into a cylinder block. The amount of cooling fluid being introduced into the cylinder block is controlled according to the engine oil temperature.

摘要： A radiator for an automotive engine has a filler neck having a coolant pass therein. The filler neck has both an inner tubular member and an outer tubular member so that the coolant pass is formed between the inner surface of the outer tubular member and the outer surface of the inner tubular member. The coolant pass is connected with a connecting pipe in order to introduce the coolant within the coolant pass toward the connecting pipe. The coolant introduced into the connecting pipe is, then, flows toward a reserve tank.Since all coolant flowing toward the connecting pipe is orientated its vector while passing through the coolant pass, the coolant can be introduced into the connecting pipe smoothly.

摘要： A pair of header plates securely brazed with a pair of side plates without causing any buckling to tubes and any deformation to the header plates. First, each tube is press-fitted into a corresponding press-fitting hole in the header plates, and at the same time, the end parts of a pair of side plates make contact with the pair of header plates. Second, flaring pins are press fitted into the end parts of the tubes in such a way that the end parts of the tubes disposed near either side of a core assembly are flared to an angle of approximately 180.degree. and the end parts of the tubes disposed in the central part of the core assembly are flared to an angle within a range from approximately 60.degree. to approximately 80.degree.. Third, cores, etc. are hung from either of the upper header plates, whichever is disposed at the upper side, and then this assembly is brazed. At this time, large widening parts with an angle of approximately 180.degree. can prevent the upper header plate from sliding downwards.

The core member is made of an aluminum alloy containing 0.3 to 1.3 wt. % of Si, 0.3 to 1.5 wt. % of Mn, 0.02 to 0.3 wt. % of Ti, and, as required, 0.3 wt. % or less of Cr and 0.2 wt. % or less of Zr, the content of Mg being restricted to 0.2 wt. % or less and the content of the Cu being restricted to 0.2 wt. % or less as an impurity. The cladding member is made of an aluminum alloy containing 0.3 to 3 wt. % of Mg, 5 wt. % or less of Zn, 0.1 to 1.0 wt. % of Si. The thickness of the core member is preferably, 2.5 times or more greater than that of the filler member, falling within a range of 0.1 to 1 mm. With this, it is possible to obtain an aluminum alloy composite material which cannot degraded in brazability and corrosion resistance even when brazed by the brazing method with noncorrosive flux and which has enough high strength to be used for a material of a high-strength heat exchanger, highly improved corrosion resistance and excellent brazability.
