A heat transfer device includes a sleeve, which forms an interior in which a working medium and one vaporization element having structural elements, or multiple vaporization elements having structural elements, for converting at least part of the working medium from the liquid to the gaseous state are contained, wherein the vaporization element or the vaporization elements has or have a porosity, and is or are connected to the sleeve.

A sintered connecting rod for an internal combustion engine comprises a connecting rod eye () for receiving a piston pin, a connecting rod big end () for holding the crank pin and a shaft () made of two diverging longitudinal bridges () which are optionally stiffened by a connecting bridge () and whose mutually facing bridge flanks () are connected in the zone of the connecting rod big end () by a central concave rounding (). In order to ensure advantageous loading conditions it is proposed that the longitudinal bridges () of the shaft () diverge from the connecting rod big end () to the connecting rod eye ().

Described is a molded part made of light metal, in particular a crankcase for an internal combustion engine, comprising holes ( ) for receiving fastening screws ( ) with the help of which compressive strains can be exerted on the molded body in a light metal area. In order to create advantageous constructional conditions, it is proposed that at least one open-pored sintered body ( ) is cast in the light metal area exposed to compressive strains with infiltration of the light metal at least in the pores of a surface layer; and that the sintered body ( ) having a lower coefficient of thermal expansion than the light metal has a strength at least corresponding with the strength of the light area when combined with the infiltrated light metal.
