板翅式机油冷却器具有传热效率高、结构紧凑、重量轻等特点。是当今车用柴油机冷却器的更新换代产品,已广泛应用于汽车,拖拉机、船用柴油机等领域中。在国内有大量需求,供求矛盾十分突出。我国生产这类板翅式机油冷却器的厂家为数不多,且均采用银铜合金焊接,每台需耗费白银150克。冶金所采用无银铜真空钎焊新工艺焊接成的冷却器,不仅为国家节约了大量贵重银材料,并且气密性好,钎焊 Plate-fin oil cooler with heat transfer efficiency, compact structure, light weight and so on. Is the replacement of the current automotive diesel engine cooler and has been widely used in the fields of automobiles, tractors, marine diesel engines and the like. There is a lot of demand in the country, the contradiction between supply and demand is very prominent. China’s production of such plate-fin oil cooler manufacturers are few, and are used silver-copper alloy welding, each need to spend 150 grams of silver. Metallurgical use of non-silver brazing vacuum welding of new technology into a cooler, not only for the country to save a lot of valuable silver material, and good airtight, brazing
