Abstract

We examine a concept and fabrication method of a microchannel-type transpiration-cooling device consisting of thermally resistant metals. The device consists of open-porous Ni-Al alloys and contains microchannel networks. Cooling water is supplied from a tank to every corner of the device through the microchannel networks, and then it seeps out to be vaporized absorbing the latent heat. The porous body of the device and the microchannel are produced by a powder-metallurgical microchanneling process using a sacrificial core.
