    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: The present application relates to a slot die coating apparatus and, more particularly, to a slot die coating apparatus which can ensure the coating stability of a substrate film by reducing pressure oscillations within a vacuum chamber when slot die coating is carried out. The slot die coating apparatus according to the present application can effectively dampen pressure oscillations within a vacuum chamber by connecting a pressure oscillation reducing tank to the vacuum chamber and thus can ensure the coating stability of a substrate film, resulting in a reduction in the proportion of defective products.

    Abstract: A polymerization reaction device of a high viscosity resin includes a cylindrical reactor having an inlet formed at an upper part and a discharge port formed at a lower part; and an impeller rotatably arranged inside the reactor and configured to mix materials in the reactor. The materials in the reactor are mixed by the impeller and polymerized into the high viscosity resin, and the polymerized high viscosity resin is discharged to an outside of the reactor through the discharge port by applying an inert gas. A ratio of a diameter of the discharge port to a diameter of the reactor may be set such that 80% or more of the high viscosity resin is discharged from the reactor from a time point when the applying of the inert gas starts to a time point when the inert gas reaches the discharge port.
