Abstract
Abstract A rectifying device is improved by arranging heat exchanging cooling pieces positioned on either side of the rectifying element in series with respect to a flow direction of cooling air circulating through the device. A sleeve element may cover the cooling pieces and the rectifier for channelling the air and reducing the spacing required between adjacent rectifier elements.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
107 words
A rectifying device, comprising: a conductor (31); first cooling means (42) electrically connected to and rigidly secured in parallel to said conductor; a securing frame (45) secured to said first cooling means; a second cooling means (41) secured to said frame; a rectifying element (1) disposed between said first and second cooling means in series with respect to a direction of cooling air flowing through said rectifier, said air flow being parallel to the line of attachment of said first cooling means to said conductor; and screw means attached to said frame for pressing said second cooling means and said rectifying element toward said first cooling means.
Claim 2
Dependent Claim
107 words
A rectifying device, comprising: a conductor (31); first cooling means (42) electrically connected to and rigidly secured in parallel to said conductor; a securing frame (45) secured to said first cooling means; a second cooling means (41) secured to said frame; a rectifying element (1) disposed between said first and second cooling means in series with respect to a direction of cooling air flowing through said rectifier, said air flow being parallel to the line of attachment of said first cooling means to said conductor; and screw means attached to said frame for pressing said second cooling means and said rectifying element toward said first cooling means.
