Cooling structure for a centrifuge
First Claim
1. A cooling structure for a centrifuge comprising:
- an outer casing;
an inner housing mounted in the outer casing;
a rotor disposed in the inner housing;
a motor comprising a motor frame disposed in the outer casing under the inner housing, said motor including a shaft for driving the rotor;
exhaust ports formed in the peripheral wall of the inner housing for exhausting therefrom gas blown off by the rotation of the rotor;
a lid covering the inner housing and having an intake for drawing gas into the inner housing as gas is exhausted from said inner housing through said exhaust ports;
a guide provided around the inner housing for guiding the gas exhausted from the exhaust ports to the upper end of the motor; and
means defining a gas passage through said motor for passing the gas guided to the upper end of the motor into the motor through holes made in said motor frame adjacent the upper end thereof and exhausting the gas from the motor through holes made in said motor frame adjacent the lower end thereof.

Abstract
In a centrifuge, a rotor is housed in an inner housing and driven by a motor disposed outside thereof. By the rotation of the rotor, gas is blown off to be exhausted from the inner housing through exhaust ports formed therein, and at the same time, gas is drawn into the inner housing through an intake formed in a lid of the inner housing to cool the rotor. A guide is provided around the inner housing, by which the gas exhausted from the exhaust ports is led to one end portion of the motor to flow into the motor through holes made in a motor frame to cool the motor. The gas passing into the motor is discharged from the other end of the motor and then expelled to the outside of an outer casing of the centrifuge.
