Cryocooler compressor

Abstract

A cryocooler compressor includes a compressor casing, and a double pipe-type heat exchanger that is accommodated in the compressor casing and cools the compressor, in which the double pipe-type heat exchanger includes a double pipe disposed along at least one surface of the compressor casing.

What is claimed is: 
     
         1 . A cryocooler compressor comprising:
 a compressor casing; and   a double pipe-type heat exchanger that is accommodated in the compressor casing and cools the compressor,   wherein the double pipe-type heat exchanger includes a double pipe disposed along at least one surface of the compressor casing.   
     
     
         2 . The cryocooler compressor according to  claim 1 ,
 wherein the double pipe is spirally bent along the at least one surface of the compressor casing.   
     
     
         3 . The cryocooler compressor according to  claim 2 ,
 wherein the double pipe is disposed to leave a space at a center portion of the at least one surface of the compressor casing.   
     
     
         4 . The cryocooler compressor according to  claim 1 ,
 wherein the double pipe is bent along at least two adjacent sides of the at least one surface of the compressor casing.   
     
     
         5 . The cryocooler compressor according to  claim 4 ,
 wherein the double pipe is disposed to leave a space at a center portion of the at least one surface of the compressor casing.   
     
     
         6 . The cryocooler compressor according to  claim 1 ,
 wherein the at least one surface includes a back surface of the compressor casing.   
     
     
         7 . The cryocooler compressor according to  claim 6 ,
 wherein the compressor casing includes a back outer frame that is provided to surround the back surface and supports the double pipe, and a back panel that is removably attached to the back outer frame to cover and hide the double pipe-type heat exchanger.
