PROCESS FOR THERMOREGULATION OF A FLEXIBLE ALVEOLAR MATERIAL BY COMPRESSION AND RELAXATION OF THE GAS STORED IN ITS HOLES AND ASSOCIATED DEVICE

摘要

The invention relates to a method for thermoregulating a flexible material. The flexible silicone or other elastomer material consists of two layers of shore hardness (H) and of different conductivity (λ) and are provided with a multitude of specific cells filled with gas. Each cell has two interconnected zones: one to store the gas during the compression of the material and which is positioned in the layer with higher hardness and thermal conductivity (layer C) and the other to relax the same gas, when the material is decompressed, in the layer with lower hardness and thermal conductivity (layer D). The flexible material can thus be used as a sole in shoes in order to maintain a cool temperature when the person is running on hot ground for example. During each step, the foot will compress the flexible material and the cell areas located in layer C will therefore act as adiabatic chambers, the gas of which, when compressed, will heat up. The higher thermal conductivity of layer C will allow better heat exchange to the outside. When the foot leaves the ground and therefore there is no more compression, the flexible material will regain its volume by the play of the elasticity of the material and the areas of cells located in the layer (D) will act like a reactor nozzle which will relax the air and therefore cool it. The lower thermal conductivity of this layer will keep this freshness.
