Embodiment Construction

[0034] Various embodiments of the present invention overcome most or all of the aforementioned problems.

[0035] Such as figure 1 As shown in , the fast absorption and extraction latent heat storage device of the present invention includes a device 1 for storing phase change material 2, which device 1 is arranged in a containment container 3 (in this embodiment, the isolation for the containment container is not shown device). The housing means 1 is in the form of a rod or tube made of elastomeric material 4 housing the PCM 2 . The heat exchange fluid 6 flows along the length of the rod 1 . The PCM 2 may preferably be added with fine nanoparticle heat transfer powders such as carbon or aluminium, in order to increase its conductivity.

[0036]The holding container 3 is shown as a hexagon, but can be of any shape, which maximizes the storage capacity for the plurality of parts 1 in the shape of a circular rod, but the rods can be of any shape, as long as they are thin enoug...

Abstract

A rapid absorption and extraction latent heat storage device according to the invention comprises a means (1) for containing at least one phase change material (2) within a containment vessel (3), the containment vessel forming a supporting structural exoskeleton. The containment means (1) is in the form of rods or tubes, which are made out of elastomeric material (4) containing the PCM (2). A heat exchange fluid (6) flows between and along the length of the rods (1).

Description

technical field [0001] The present invention relates to efficient thermal energy storage devices capable of rapid absorption and extraction. Background technique [0002] In recent years there has been an increasing need to store energy, usually electricity. With the present invention it is now possible to efficiently store thermal energy which can be used for power generation, cooling, heating or for any purpose at a later date. [0003] There have been several inventions (eg WO8900670, Whitman) showing various methods of using phase change materials (PCMs) to store thermal energy, but they all have fundamental problems. For the wax variety of PCM, the main problem centers on its poor thermal conductivity and relatively large coefficient of thermal expansion. [0004] Thermal conductivity is significantly better for eutectic and hydrated salt type PCMs, but corrosion can become a major problem. All current PCMs have problems with expansion and contraction, which makes th...
