Development level.Whole disclosure contents of each of these patent and publications are incorporated herein by reference.
Phase-change material (PCM) is the latent heat storage material that can absorb and discharge a large amount of latent heat during fusing and crystallization.
When material from solid phase be changed into liquid phase or from liquid phase be solid phase when, occur heat energy transfer.During this class phase transformation, the PCM
The temperature of material keeps nearly constant, and the space around the PCM material is also in this way, the heat for flowing through the PCM is existed by " retention "
In the PCM itself.In other well known PCM, paraffin is commonly used, because of its low cost and hypotoxicity.
PCM can be introduced into the matrix being made from a different material or they can be used as coating to apply.See, for example,
U.S.4,003,426、U.S.4,528,328、U.S.5,053,446、U.S.2006/0124892(WO 2006/062610)、WO
98/04644 and WO 2004/044345.
In order to easily use PCM in thermal management applications, PCM is attached in matrix polymer, these matrix
Polymer even absorbs at a temperature of higher than PCM fusing points and keeps the PCM, and thus makes it possible to by gained PCM composite woods
Material is manufactured into the sheet, panelling or other shapes being easily mounted on wall.However, most of matrix polymers are limited by a variety of lack
It falls into, for example, limited PCM absorptive capacities or any substantial loss for passing through PCM caused by extrusion in the lifetime of product.To this
The partial solution of a little problems carries in WO 2006/062610, WO 2011/143278 and WO 2011/014636
