A porous heat exchanger comprises a heat exchange tube (50, 90, 110, 130, 150, 170, 190, 210), a porous body (51, 91, 111, 131, 151, 171, 191, 211), a fluid inlet end (53), and a fluid outlet end (54). The heat exchange tube (50, 90, 110, 130, 150, 170, 190, 210) and the porous body (51, 91, 111, 131, 151, 171, 191, 211) are made of solid materials with good heat conductivity. The porous body (51, 91, 111, 131, 151, 171, 191, 211) is located in the heat exchange tube (50, 90, 110, 130, 150, 170, 190, 210) and divides the interior of the heat exchange tube (50, 90, 110, 130, 150, 170, 190, 210) into the fluid inlet end (53) and the fluid outlet end (54), and the porous body (51, 91, 111, 131, 151, 171, 191, 211) is tightly connected to the heat exchange tube (50, 90, 110, 130, 150, 170, 190, 210) to ensure effective heat transfer. Multiple holes (52, 92, 112, 153, 172) through which fluid passes are formed in the porous body (51, 91, 111, 131, 151, 171, 191, 211), and accordingly the fluid can flow in from the fluid inlet end (53) of the porous heat exchanger, passes through the multiple holes (52, 92, 112, 153, 172) in the porous body (51, 91, 111, 131, 151, 171, 191, 211) and then smoothly flows out from the fluid outlet end (54) of the porous heat exchanger. The porous heat exchanger shortens the heat transfer distance between a cold source and a heat source, greatly increases the heat exchange area within the limited length of the heat exchange tube (50, 90, 110, 130, 150, 170, 190, 210), and implements efficient heat exchange of the fluid. |
