Abstract

Improved cooling of a printer hammer assembly is provided by a finned mounting bar for dissipating the heat generated by the hammer coils. As shown in Fig. 1, heat generated by the hammer coils 1 within the hammer assembly is conducted away from coils 1 through stator arm 2 to the hammer block 3. From block 3 the heat is conducted to the fins 4 of mounting bar 5. The air is ducted through fins 4 by the air flow plenums 6. Forced air cooling of the circuit components 7 on the hammer cards 8 is also provided by the air exiting from the fins 4, as shown by arrows 9. Details of the fins are shown for the top half of the hammer cooling assembly in Fig. 2.
