摘要

The heat storage device comprises an insulated storage container (100), which encloses a storage volume (110), caps (180), which comprises a phase change material, an inlet (120) with a first support unit (121) and an outlet (130) with a second support unit (131). The support units are arranged in such a manner that the caps are not rinsed by the inlet or outlet. The outlet pipe comprises holes and a wire mesh, its mesh diameter is smaller than the diameter of the caps. The outlet comprises a metal network having a mesh diameter, which is smaller than the diameter of the caps. The heat storage device comprises an insulated storage container (100), which encloses a storage volume (110), caps (180), which comprises a phase change material, an inlet (120) with a first support unit (121) and an outlet (130) with a second support unit (131). The first and second support units are arranged in such a manner that the caps are not rinsed by the inlet or outlet. The outlet pipe comprises holes and a wire mesh, its mesh diameter is smaller than the diameter of the caps. The outlet comprises a metal network, which has a mesh diameter, which is smaller than the diameter of the caps. The caps comprise a flexible material and an additional mass, so that a volume variation of the phase change material leads to a volume variation of the cap. The phase change material represents paraffin and/or salt hydrate. The outlet pipe is made of high-grade steel and the loaded phase change material is arranged in direct proximity to the high-grade steel pipe. The caps sink after unloading to base and the high-grade steel pipe is brought into direct contact to the heat transmitting medium. An independent claim is included for a heat storage caps.
