The equipment is improved aiming at the defects of material use and riveting connection existing in the traditional oil cooler, and develops a stamping die suitable for a ferritic stainless steel material with higher strength on the basis of the traditional austenitic material;

in the production process of the product, the traditional sheet riveting mode is cancelled, vacuum high-temperature brazing is carried out after direct stacking, the connecting parts of the whole oil cooler are welded and fixed by adopting a brazing process, the sealing performance of the oil cooler is guaranteed, the whole oil cooler is made of ferrite stainless steel materials with higher strength, and the strength of the product is improved.

As shown in fig. 1 to 6, the present invention provides a technical solution: a riveting-free ferrite oil cooler comprises outer core plates 1, wherein a plurality of outer core plates 1 are vertically arranged, inner core plates 2 are fixedly connected between every two adjacent outer core plates 1, a water-side space ring 4 is fixedly connected between each inner core plate 2 and the joint of the outer core plate 1 positioned at the top of the inner core plate 2, oil fins 3 are fixedly connected between each inner core plate 2 and the joint of the outer core plate 1 positioned at the bottom of the inner core plate 2, through holes are formed in the joints of the outer core plates 1 and the inner core plates 2 in a vertically penetrating manner, two joints of the outer core plates 1 and the inner core plates 2 are arranged, a flange joint 5 is fixedly connected above the through hole at the top of the uppermost outer core plate 1, connecting holes connected with the through holes are formed in the top of the flange joint 5, the flange joint 5 is of a rounded triangle structure, fixing holes are respectively formed in two sides of the connecting holes at the top of the flange joint 5, and the outer core plates 1 and the inner core plates 2 are of a Z-shaped structure, through-hole department of adjacent outer core plate 1 and inner core plate 2 is opposite direction turn-ups, and it is fixed through brazing between adjacent outer core plate 1 and the inner core plate 2, is located 1 bottom fixedly connected with shrouding 6 of outer core plate of below, and shrouding 6 is located the through-hole below and seals the through-hole, and 6 bottom centers of shrouding department are provided with circular pit.

It should be noted that, by adopting the rivet-free structure between the outer core board 1 and the inner core board 2, the outer core board 1 and the inner core board 2 are provided with multiple layers according to different use scenes, thereby meeting the heat dissipation requirement, the oil fins 3 arranged between the outer core plate 1 and the inner core plate 2 are used for dissipating the heat of the high-temperature oil, meanwhile, the water side space ring 4 can ensure the sealing performance of the joint of the outer core plate 1 and the inner core plate 2, the brazing connection mode can avoid deformation caused by riveting, thereby avoiding the weakening of the structural connection strength of the final product, simultaneously improving the price advantage of the product, and simultaneously, ferrite stainless steel is adopted to replace the traditional austenite 304 stainless steel material, so that the problems that the strength and the heat conduction performance of the 304 stainless steel are weak, and the plate deformation is caused by the peripheral riveting structure are solved, and the strength and the heat exchange performance of the product can be further improved.
