Abstract

For the production of a heat storage means, more particularly in the form of 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 in inner container arranged in spaced relationship to the outer container so as to include an insulating zone between them, a heat storage core arranged in the inner container and having at least one chamber for a 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, a high quality insulation may be produced without thermal damage in a substantially shorter period of time, which is economically acceptable and the insulation may be sufficiently long lasting for use in automobiles, if after the insulating zone has been heated after the production of the housing for degassing and has been evacuated, the bake out is performed at a temperature which is substantially above the operational temperature of the core and said components of the heat storage core are then protected against any temperature-dependent damage to the heat storage core.
