Cylinder Head For A Compressor With Particularly Efficient Air Cooling

Abstract

A cylinder head is provided for a compressor, including at least one coolant-conducting region and at least two air-conducting regions. The at least one coolant-conducting region is arranged at least partially around the at least two air-conducting regions. The at least two air-conducting regions have at least one air-feeding duct for feeding the air to be compressed into the compressor and at least one air-discharging duct for outputting a compressed air which is compressed by the compressor. The at least one air discharging duct includes an open-pore, metallic cell structure.

What is claimed is: 
     
         1 . A cylinder head for a compressor, comprising:
 at least one coolant-conducting region;   at least two air-conducting regions, wherein   the at least one coolant-conducting region is at least partially arranged around the at least two air-conducting regions,   the at least two air-conducting regions have at least one air-supplying duct for feeding air to be compressed into the compressor and at least one air-discharging duct for outputting compressed air compressed by the compressor, and   the at least one air-discharging duct comprises an open-pore metallic cell structure.   
     
     
         2 . The cylinder head as claimed in  claim 1 , wherein the at least one air-discharging duct is at least partially configured as an open-pore metallic cell structure. 
     
     
         3 . The cylinder head as claimed in  claim 1 , wherein the open-pore metallic cell structure is produced by using inserts. 
     
     
         4 . The cylinder head as claimed in  claim 1 , wherein the open-pore metallic cell structure is produced by mechanical manufacturing. 
     
     
         5 . The cylinder head as claimed in  claim 1 , wherein the open-pore metallic cell structure is produced by a lost-foam method. 
     
     
         6 . The cylinder head as claimed in  claim 1 , wherein the open-pore metallic cell structure is produced by foaming. 
     
     
         7 . A method for producing a cylinder head, comprising:
 at least one coolant-conducting region;   at least two air-conducting regions, wherein   the at least one coolant-conducting region is at least partially arranged around the at least two air-conducting regions,   the at least two air-conducting regions have at least one air-supplying duct for feeding air to be compressed into the compressor and at least one air-discharging duct for outputting compressed air compressed by the compressor, and   the at least one air-discharging duct comprises an open-pore metallic cell structure, wherein the method comprises the acts of:   casting the cylinder head as a thin wall casting, and   subsequently, casting an expandable metallic material therein, said material being expanded to form the open-pore metallic cell structure.   
     
     
         8 . A method for producing a cylinder head, comprising:
 at least one coolant-conducting region;   at least two air-conducting regions, wherein   the at least one coolant-conducting region is at least partially arranged around the at least two air-conducting regions,   the at least two air-conducting regions have at least one air-supplying duct for feeding air to be compressed into the compressor and at least one air-discharging duct for outputting compressed air compressed by the compressor, and   the at least one air-discharging duct comprises an open-pore metallic cell structure, wherein the method comprises the acts of:   placing the open-pore metallic cell structure as a preshaped semi-finished product into a casting mold, and   insert molding to form the cylinder head.   
     
     
         9 . The method as claimed in  claim 8 , wherein a negative mold of the open-pore metallic cell structure is placed into the casting mold. 
     
     
         10 . A compressor comprising a cylinder head as claimed in  claim 1 . 
     
     
         11 . A compressor comprising a cylinder head as claimed in  claim 2 . 
     
     
         12 . A compressor comprising a cylinder head as claimed in  claim 3 . 
     
     
         13 . A compressor comprising a cylinder head as claimed in  claim 4 . 
     
     
         14 . A compressor comprising a cylinder head as claimed in  claim 5 . 
     
     
         15 . A compressor comprising a cylinder head as claimed in  claim 6 .
