Abstract (en)
[origin: DE19815777A1] The invention relates to a heat accumulator, especially a PCM device, provided with thermal insulation (4), at least one inlet (2) and one outlet (3), and collector areas (12) for the heat carrier medium that are fluidically connected to the storage core which is surrounded by a housing, whereby flow paths (tubes) (5) are arranged therein and the inventive device is provided with areas in between the flow paths where phase change material can be found. Such heat accumulators can be more easily adapted to small, angular installation areas while at the same time maintaining a storage capacity, high load and unload dynamic characteristics and can be produced inexpensively when the flow paths (5) are made of oval or flat tubes which are conducted through the storage core in a spiral or undulated form and the areas (9) for the phase change material are arranged between the individual flow paths (5) and the undulated shapes (10) or windings (18) of the individual flow paths (5) and are at least for the most part taken up by heat conducting elements (8) which are metallically connected to the flow paths (5). The heat conducting elements (8) are configured as undulated thin strips of sheet metal whose width is greater than the large diameter of the tubes that form the flow paths (5).
