Abstract

The trend in recent years in copiers has been toward miniaturization and high speed operation. In reducing the size of copiers, it is requisite that every constituent unit of the apparatus be smaller and the copier as a whole be highly condensed. One problem that occurs in such. miniaturization and condensation is a rise in temperature within the copier. Actually this is a problem for large as well as small copiers due to the use of fusers, fast moving machine parts, electrical systems, lamps, etc. The temperature is presently controlled by electric powered fans as shown, for example, in U.S. Patent 4,401,385. However, the drive toward cheaper copiers requires a more economical means of exhausting unwanted heat.

COPIER ENVIRONMENT COOLING USING NITINOL ENGINES (Cont'd)

The trend in recent years in copiers has been toward miniaturization and high speed operation. In reducing the size of copiers, it is requisite that every constituent unit of the apparatus be smaller and the copier as a whole be highly condensed. One problem that occurs in such. miniaturization and condensation is a rise in temperature within the copier. Actually this is a problem for large as well as small copiers due to the use of fusers, fast moving machine parts, electrical systems, lamps, etc. The temperature is presently controlled by electric powered fans as shown, for example, in U.S. Patent 4,401,385. However, the drive toward cheaper copiers requires a more economical means of exhausting unwanted heat.

A solution is shown in the Figure where a low cost "Nitinol" engine
(U.S.Patent 4,275,566) is used to replace electric powered fans. Not only will the "Nitinol" engine absorb heat, but the mechanical energy can be used to drive a fan to exhaust the remaining heat as shown. Nitinol is an alloy which derived its generic name from Nickel and Titanium, and from its birthplace, the Naval Ordinanc...
