包括梯变的多孔结构的用于流体通流的装置
摘要：
一种流体通流装置(10)，所述流体通流装置包括流体入口(12)和流体出口(13)、以及具有互相连通的孔隙的多孔结构(15)，所述多孔结构布置在所述流体入口与所述流体出口之间。所述流体入口和所述流体出口限定整体流动方向(14)。所述多孔结构联接到壁(111)以在所述多孔结构与所述壁之间提供热传导，并且包括沿与所述整体流动方向交叉的第一方向(17)的孔隙率梯度。所述孔隙率梯度沿所述第一方向在靠近所述壁的第一位置(158)处的第一孔隙率(P3)与远离所述壁的第二位置(156)处的大于所述第一孔隙率的第二孔隙率(P1)之间发展，所述第二孔隙率与所述第一孔隙率之间的差值为至少4％。
摘要（英）：

Device (10) for through-flow of a fluid, comprising a fluid inlet (12) and a fluid outlet (13), and a porous structure (15) with interconnected pores arranged between the fluid inlet and the fluid outlet. The fluid inlet and the fluid outlet define an overall flow direction (14). The porous structure is coupled to a wall (111) to provide for heat conduction between the porous structure and the wall, and comprises a porosity gradient along a first direction (17) which is cross to the overall flow direction. The porosity gradient develops along the first direction between a first porosity (P3) at a first location (158) proximal to the wall and a second porosity (P1) larger than the first porosity at a second location (156) remote from the wall, the difference between the second porosity andthe first porosity being at least 4%.
