| 摘要 |
The invention is a footwear sole (1) comprising a heat exchange system (2) provided with means (3) for compressing a heat exchange fluid (4) comprising a non-deformable chamber (31) communicating with a condensation unit (6) and an evaporation unit (5), and a pumping unit (32) with an expandable chamber (33) positioned inside the non-deformable chamber (31), and a compressible chamber (34) positioned out of the same, interconnected by means of a non-deformable pipe (35). The pumping unit (32) makes an auxiliary fluid (11) circulate from the compressible chamber (34) to the expandable chamber (33), so that the heat exchange fluid (4) flows outside the non-deformable chamber (31) when the pressure exerted by the foot (P) on the sole (1) compresses the compressible chamber (34), and furthermore forces the auxiliary fluid (11) to flow from the expandable chamber (33) to the compressible chamber (34), in order to allow the heat exchange fluid (4) to flow back inside the non-deformable chamber (31) when the pressure exerted on the compressible chamber (34) decreases. |
