Abstract
A cooled print hammer assembly in which a plurality of hammer coils are formed in a resin member having a recess in which is placed a cooling fin. The opened faces of the fins are placed adjacent a plate of the frame of the print hammer assembly so that closed forced-air ducts are defined by the fins and the frame plate. Additionally, partitions may be placed on the sides of the fins so that the external sides of the fins are cooled.
