Abstract
The present invention is a paper shredder with an enhanced heat dissipation device, having a fan mounted on at one end of a motor inside a casing of the paper shredder. The fan will be running at the same time that the motor starts or operates to a specific temperature, thereby facilitating the heat dissipation of the motor, providing for long term operation of the paper shredder, and improving the operating efficiency of the paper shredder.
Claims2
A paper shredder with a heat dissipation device comprising:
- a paper shredder outer casing adapted for shredding knives on a first side and a shredding knives drive motor on a second side opposite the first side, and having a plurality of venting holes on the paper shredder outer casing arranged in two groups, one group near each end of the drive motor side;
- a plurality of paper shredding knives mounted with a horizontal axis inside the first side of the paper shredder outer casing;
- a drive motor for the plurality of paper shredding knives, disposed inside the second side of the paper shredder outer casing, having
- a drive end and an second end,
- a drive motor casing,
- an axis parallel to and offset along side of horizontal axis of the plurality of paper shredding knives;
- and
- a fan mounted to the second end of the drive motor, and having
- an electrical drive, and
- a drive shaft that is parallel to the plurality of paper shredding knives and separate from the drive motor;
- whereby the heat dissipation of the drive motor is facilitated.
