In addition, mute oil free compressor USES air convection principle, to achieve the naturalcooling effect.
另外，静音无油空压机采用空气对流原理，达到自然冷却效果。

Three-dimensional physical and mathematical models for the coupled heat transfer of naturalconvection in a liquid pool with heat source and forced convection in cooling coil tube are established.
By means of naturalconvection air-cooling burner spray and auxiliary ports installation, the load regulation range of the atmospheric burner with single port is extended.
