Stirling engine regenerator

Abstract

The invention disclosed a Stirling engine regenerator, including a cylindrical regenerator cover, one end of the regenerator cover is connected with a heater and the other end is connected with a cooler. The end of the regenerator which is near the heater is provided with the first metal wire mesh, the other end of the regenerator which is near the cooler is provided with the second metal wire mesh. The regenerator is located in the cavity between the first metal wire mesh and the second metal wire mesh. The carbon fiber body filled the whole cavity. Carbon fiber body has the characteristics of high temperature resistance, high thermal conductivity and corrosion resistance and using the filling type. The manufacturing costs are very low with long service life and the contact area between the air and the carbon fiber body is large. So the heat transfer efficiency is high.

1 . A Stirling engine regenerator, including a cylindrical regenerator cover ( 1 ) is connected with a heater on one end ( 2 ), the other end is connected with a cooler ( 3 ), its characteristic is, the end of the regenerator cover( 1 ) which is near the heater is provided with the first metal wire mesh ( 4 ), the other end of the regenerator cover which is near the cooler is provided with the second metal wire mesh ( 5 ), the regenerator cover ( 1 ) mentioned above is located in the cavity between the first metal wire mesh and the second metal wire mesh. The whole cavity is filled with the carbon fiber body ( 6 ). 
     
     
         2 . According to the right requirement  1 , A stirling engine regenerator, its characteristics are, the exteriors of the first metal wire mesh ( 4 ) and the second metal wire mesh ( 5 ) are provided with metal mesh fixed plate ( 7 ). The metal mesh fixed plate ( 7 ) is connected with the regenerator cover ( 1 ), the first metal wire mesh ( 4 ) and the second metal wire mesh ( 5 ) are welding with the interior of the metal wire mesh fixed plate ( 7 ).There are some air vents ( 8 ) on the metal wire mesh fixed plate ( 7 ). 
     
     
         3 . According to the right requirement  2 , A stirling engine regenerator, its characteristics are, the diameter of the air vents reaches its highest in the center of the metal mesh fixed plate and decrease gradually from the center to the periphery, the air vents which locate on the same corresponding radius of the metal mesh fixed plate share the same diameter. 
     
     
         4 . According to the right requirement  1 , a Stirling engine regenerator, its characteristics are, the carbon fiber body ( 6 ) including the first carbon fiber body ( 61 ) and the second carbon fiber body ( 62 ). The first carbon fiber body ( 61 ) is cylindrical structure, there is metal filter ( 9 ) inside the regenerator cover ( 1 ), metal filter ( 9 ) divide the cavity of the regenerator cover into two parts, the part which is near the heater ( 2 ) is called the Heat transfer section and the other part which is near the cooler ( 3 ) is called the cooling section. The first carbon fiber body ( 61 ) filled the heat transfer section and the second carbon fiber body ( 62 ) filled along the regenerator cover evenly and tightly. 
     
     
         5 . According to the right requirement  4 , a Stirling engine regenerator, its characteristics are, the second carbon fiber body ( 62 ) is spiral structure; its two adjacent spirals are fit closely. The two ends of the second carbon fiber body ( 62 ) connected with the second metal wire mesh ( 5 ) and the metal filter ( 9 ) separately. The outer rings of the two adjacent second carbon fiber bodies ( 62 ) are connected with each other.
