Method of manufacture of a heat accumulator, in particular of a latent heat accumulator, and accumulator for implementing this method

摘要

The present invention relates to a method of manufacture of a heat accumulator including an outer container (12) and an inner container (14), in particular a latent heat accumulator, the outer container and the inner container delimiting together an insulating region (16) produced by heating and evacuation. This method is characterised in that the insulating region (16) is first heated and evacuated and the accumulated fluid is then introduced into the accumulation region.
