Abstract: A hollow profile and a method of producing the hollow profile from a hardenable steel alloy blank is disclosed having an L-shaped cross section with an upper vertical hollow chamber, and a lower horizontal hollow chamber, wherein the blank comes in abutment on an intermediate bridge area, forming a double layer. The hollow profile further includes, at least in regions, a tensile strength Rm greater than 1000 MPa.

Abstract: A motor vehicle heat exchanger system with a closed circuit for an operating medium includes an evaporator for evaporating the operating medium and a condenser for condensing the vaporous operating medium AM is provided. A reservoir for the liquid operating medium is integrated between the condense and the evaporator. Liquid operating medium is conducted from the reservoir via a feed line into the evaporator. In addition the reservoir and the evaporator are connected with each other via a compensation line. Vapor which may form during operation of the motor vehicle heat exchanger system on the liquid side of the evaporator can escape through the compensation line thereby achieving a pressure compensation.
