FIELD: heat storage plants or apparatus in general, particularly ones using latent heat. ^ SUBSTANCE: latent heat accumulation device comprises salt case, inlet and outlet pipes extending from outer jacket outside to salt case interior and at least one pipe installed in the salt case. A number of straight parallel paths are defined in the device. The paths create matrix with outer part. At least one pipe is filled with phase-change material sealed inside the pipe. The paths are formed as equilateral polygon. Each path extending from outer matrix part inside it adjoins a number of adjacent paths. Each path at outer matrix part additionally contacts with salt case. Latent heat accumulation device includes salt case, inlet and outlet pipes extending to salt case interior and at least one pipe installed in the salt case. A number of straight parallel paths are defined in the device. The paths create matrix with outer part. At least one pipe is filled with phase-change material sealed inside the pipe. The paths are formed as equilateral polygon. Each path inside outer matrix part adjoins a number of adjacent paths. Each path at outer matrix part additionally contacts with salt case. The path cross-sections are shaped so that flow passage spaces are created between the paths. The spaces fluidly communicate with inlet and outlet pipes. Latent heat accumulation device includes salt case, outer jacket surrounding the salt case so that a gap is created in-between. The gap defines insulation space between salt case and outer jacket. The device also has inlet and outlet pipes extending from outer jacket outside to salt case interior and at least one pipe installed in the salt case. A number of straight parallel paths are defined in the device. The paths create matrix with outer part. At least one pipe is filled with phase-change material sealed inside the pipe. The paths are formed as equilateral polygon. Each path inside outer matrix part adjoins a number of adjacent paths. Each path at outer matrix part additionally contacts with salt case. ^ EFFECT: decreased size and weight and increased heat accumulation capacity. ^ 18 cl, 5 dwg |
