ABSTRACT:
In a method for the production of a heat storage means, more particularly in the form of a latent heat storage means, for vehicle heating systems run on heat from the engine, comprising a housing, which is made up of an outer container and an inner container arranged in spaced relationship to the outer container so as to constitute an insulating vessel including an insulating zone, a heat storage core arranged in the inner container and having at least one chamber for a heat storage medium in it, said chamber being separated by a partition wall from at least one flow path for a heat transfer medium, and an inlet duct and outlet duct for the heat transfer medium, such ducts being connected with the flow path and extending outwards through the insulating zone, the insulating zone having been baked out in the housing for degassing and having been evacuated. In the range between the filling temperature of the storage when being being charged into the storage zone, and the maximum temperature occurring thereafter the volume of the storage medium changes with temperature to a greater extent than the respective chamber volume. There the amount of the filling charge of the storage medium is made such that at the maximum temperature occurring the volume of the storage medium is at the most equal to the associated chamber volume.
