Title: Cooling structure for enclosed type compressor
Inventor: IIDA TOSHIKATSU
IPC: F04B39/06
Filed: 1983-10-26
Abstract: PURPOSE:To improve the cooling efficiency of the cooling part of a compression part and to provide an increased life through prevention of production of carbon sludge, by a method wherein a material having the high coefficient of thermal radiation is coated on the outer surface of the compression part of an enclosed type compressor and the inner surface of an enclosed casing. CONSTITUTION:Surface oxide layer 11 of a material having high radiation rate, i.e., a metallic oxide, such as iron oxide, iron phosphate which has a thermal radiation rate of, for example, 0.8 or more, is formed on the outer surface of a compression part 4 consisting of a valve cover 9, a cylinder head 8, and a cylinder 6, which are all made of cast iron or aluminium with a thermal radiation rate of 0.3 or less. This causes radiation of a heat.
