Patent number: 10495385Abstract: A heat exchange device of a floating core type, having a special configuration which allows increasing its durability as it increases its thermal fatigue resistance. The device is characterized by a configuration having high thermal fatigue resistance due to the special configuration of the end where the floating side of the core is located since stagnation regions that are usually produced in the baffle of the floating end are eliminated by the combination of the shape of the shell and of a deflector. This configuration furthermore results in a low-cost exchanger.Type: GrantFiled: April 19, 2016Date of Patent: December 3, 2019Assignee: Borgwarner Emissions Systems Spain, S.L.U.Inventors: José Antonio Grande Fernández, Germán Troncoso
