    Abstract: A heat exchanger including: an inlet portion having a first flow path through which a fluid is introduced; a main body including a shell and a plurality of tubes. The shell has an internal space and one surface that has a plurality of penetration holes and a cross-sectional area larger than a cross-sectional area of the first flow path. Each of the plurality of tubes allows the fluid to flow therethrough, and is positioned in the internal space of the shell. An expanded tube portion connects the inlet portion and the one surface of the shell and has a second flow path. The heat exchanger also includes a fluid flow distributor disposed in the second flow path to distribute the flow of the fluid. No other member is disposed between the inlet portion and the multiple ring members.

    Abstract: A method for manufacturing polysilicon, according to the present invention, is capable of manufacturing polysilicon with high purity more efficiently in such a manner that a high-temperature and high-speed air stream is formed at the center of a reaction tube, and a high-temperature region may be formed by a vortex formed by the high-temperature and high-speed air stream, so that a raw gas supplied from the side wall of the reaction tube flows by the guiding of the vortex, thereby increasing a stay time and a reaction time of the raw gas within the reaction tube. Furthermore, since the inner wall of the reaction tube is provided with a heat release means, the rapid cooling of a silicon crystal deposited on the inner wall of the reaction tube can induce a columnar crystal in which the silicon crystal is solidified in a direction perpendicular to a crystal face, and it is easy to desorb the silicon crystal produced by rapid heat release via the inner wall of the reaction tube.

    Abstract: The present application relates to a mixer and a mixing method and, more specifically, to a pipe-type mixer for low-flow dispersion of immiscible liquids. The mixer, according to the present application, comprises: a pump(30) provided in a liquid transport section so as to supplement a deficient flow velocity, when materials to be mixed such as liquids are mixed through a continuous mixing step; and static mixers(22) suitable for the dispersion of the materials to be mixed by increasing a diameter of mixing parts(20) provided in a circulation pipe(10). Thus, a mixing rate of mixed materials can be more efficiently increased when the materials are mixed by using the static mixers(22).
