On the surface of the cylinder fins, the presence of the boundary layer causes the flow of cooling air to "displace" outwardly along the normal direction of the fins, which is equivalent to adding an apparent thickness to the fins. The biggest success of Brahsius is to solve the numerical calculation method of the thickness of the laminar flow layer. Due to the enhanced heat transfer technology adopted in the compressor, the forced cooling measures can reduce the thickness of the boundary layer, which means that the increase of the temperature gradient causes the compressor to increase the heat transfer to the outside, thereby achieving the purpose of reducing the temperature of the compressor system. . According to the Brahsius solution of the flat layer of the flat plate, if the thickness of the boundary layer is defined from the surface of the heat sink (normal direction) until the fluid velocity reaches 0.99 times the flow velocity outside the layer, the thickness of the boundary layer is usually a few millimeters. level. This shows that after the effective forced cooling measures are implemented, the influence of the thickness of the surface layer of the fin surface on the heat transfer is limited, clarifying some fuzzy understanding of the boundary layer of the cylinder fin. The temperature field of the cylinder surface of W-0.37/9.6 air compressor was verified by the test from the scientific nature of the low-speed viscous fluid in the flat-plate boundary layer. The effect of the cylinder fins on the crankcase lubricant temperature is the oil temperature profile. The temperature of the crankcase lubricating oil depends on the heat transferred from the parts above the crankcase to the crankcase. If the temperature of some parts above the crankcase is high, the temperature of the lubricating oil will be higher; vice versa. The use of enhanced heat transfer technology is essential for the design of air-cooled compressors. Reasonable design of the heat sink of each part of the compressor can fully utilize the heat transfer efficiency of the heat sink, minimize the temperature of each part of the compressor temperature field, and rationally utilize the material to achieve twice the result with half the effort. In addition, enhancing the cooling of the compressor can reduce the power loss of the compressor from the isotherm during compression and expansion. Some basic scientific research results such as fluid mechanics and aerodynamics can help us solve design problems theoretically and guide the design in the right direction.
