HEAT ACCUMULATOR, IN PARTICULAR FOR LATENT HEAT

摘要

Proposed is a heat accumulator, in particular a latent-heat accumulator, with an inner casing (11) containing the accumulator core and an outer casing (12) surrounding the inner casing (11) to leave an insulation gap (13) between them, the insulation gap (13) being baked out and evacuated. The inner casing (11) has a pipe connection (15) with a filler opening (14) through which the heat-storage fluid is introduced and which is closed by means of a mechanical closure (16) after the fluid has been introduced. The outer casing (12) has a pipe connection (22) with a filler opening through which the insulation gap (13) is filled with insulating agent and/or evacuated and which is closed by means of a mechanical closure (23). The pipe connection (15) in the inner casing (11) is disposed coaxially to the pipe connection (22) in the outer casing (12). This simplifies the manufacture of the heat accumulator.
