A cooling arrangement for an at least two-stage compressed air generator comprises an intercooler arranged between a first and a second compressor stage, an aftercooler arranged after the second compressor stage, and a subassembly cooler, which absorbs heat from further subassemblies of the compressed air generator. A coolant circuit comprises a main cooler, the cold side supplying a cooled coolant parallel to the respective coolant inlet of the intercooler, of the aftercooler and of the subassembly cooler, and the hot side receiving the heated coolant exiting in parallel at the respective coolant outlet of the intercooler and of the aftercooler. The coolant outlet of the subassembly cooler is connected to a feed inlet of the intercooler and/or of the aftercooler.

Cooling arrangement and method for cooling an at least two-stage compressed air generator

A cooling arrangement for an at least two-stage compressed air generator. The cooling arrangement comprises an intercooler arranged between a first and a second compressor stage, an aftercooler arranged after the second compressor stage, and a subassembly cooler, which absorbs heat from further subassemblies of the compressed air generator. A coolant circuit comprises a main cooler, the cold side supplying a cooled coolant parallel to the respective coolant inlet of the intercooler, of the aftercooler and of the subassembly cooler, and the hot side receiving the heated coolant exiting in parallel at the respective coolant outlet of the intercooler and of the aftercooler. The coolant outlet of the subassembly cooler is connected to a feed inlet of the intercooler and/or of the aftercooler.

The invention is related to a pulsation muffler () for a gaseous medium flow (), which is supplied by a compressor. The pulsation muffler () comprises a housing () extending along a central axis with a medium flow inlet () and a medium flow outlet; several tubular absorber elements () concentrically arranged in the housing () and fluidically arranged one behind the other. Each tubular absorber element () is provided with an inlet area and an outlet area, positioned at an axial distance from each other. Between the respective radially adjacent wall sections of different absorber elements (), a flow compartment () is maintained for the medium flow ().

Pulsation mufflers for compressors

A compressor system () with a system housing (), in which are arranged heat generating system components () comprising at least one compressor stage () for compressing a gaseous medium, an air water cooler (), a blower () which generates a cooling air flow (), and air conducting elements. A cooling air channel () is configured which has an inlet opening () in the upper section of the system housing () and an outlet opening () in the lower section of the system housing (), wherein upper air conducting elements () are positioned in order to conduct the cooling air flow () after flowing through the air water cooler () to the inlet opening (), and lower air conducting elements () are positioned in order to conduct the cooling air flow () from the outlet opening () to the system components ().
