摘要： The same number of grooves 20 through 27 are provided in end surfaces 19a and 19b of a roller 19. The grooves 20 through 27 have communicating portions 20a through 27a which communicate with an inner peripheral side of the roller 19 and sealed portions 20b, 20c, 20d, 20e, 20f through 27b, 27c, 27d, 27e and 27f each of whose cross-sectional area decreases. Accordingly, the cross-sectional area is decreased in direction in which a lubricating oil flows, and a plurality of oil pressures can thus be obtained. This results in a fixed clearance of roller 19.

摘要： Disclosed are plate-shaped fins for a heat exchanger having a coated film formed thereon so that waterdrops can easily fall down from the surface of the plate-shaped fins, the coated film being composed of a solution containing a silicone coating film type resin compound and inorganic finely divided particles. Further, the inorganic finely divided particles are used to provide fine irregular portions on the surface of the coated film formed on the plate-shaped fins so that the area where the waterdrops come into contact with the surface of the fins is reduced.

摘要： A heat exchanger is provided in an air conditioner, refrigerator or the like, and is provided for the indirect transmission and reception of heat between fluids. The heat exchanger comprises a plurality of flat plate fins which are arranged parallel to one another at predetermined intervals so as to allow air stream to flow therebetween, and a plurality of heat transfer tubes passing through the flat plate fins for allowing a fluid to flow therethrough. Each fin is provided with a number of groups of air vents arranged to cross the wake side of the air stream. Each of the air vents is defined by a slat having four sides in which two sides, facing the air stream, are opened and other two sides are provided with leg portions for connecting the slat with the fin. The leg portions are aligned with each other and are inclined with respect to the normal line of the leading edge of the fin. With the above structure, a swirling and a turbulent component of air are induced in the air stream flowing between the fins thereby improving the heat transfer efficiency of the fins.
