摘要： This invention relates to an oil cooler suitably applied to a hydraulic circuit for a power steering unit, and a method of manufacturing the same. The oil cooler according to the present invention consists of a tube bundle composed of a plurality of parallelly arranged tubes, volume chambers provided at both ends of the tube bundle, and a plurality of cooling fins fitted around the tubes, and is characterized in that it is made compact, has a high cooling capacity and a high torsional rigidity and can suppress the occurrence of noise. The method of manufacturing oil coolers according to the present invention is caracterized by comprising the steps of: (A) producing cooling fins by piercing in sheet materials to be worked into cooling fins a plurality of holes having axially projecting edges through which a plurality of tubes are to be inserted and further forming pores in the vicinity of the holes through which threadlike soldering material is to be inserted, (B) fitting the holes of the cooling fins around the tubes and inserting the soldering material through the pores of the cooling fins, and (C) melting the soldering material to bond the projecting edges of the cooling fins with the tubes. Thus an oil cooler can be manufactured simply at a low cost.
