ABSTRACT:
A laboratory centrifuge having a housing which can be closed by a casing cover and having in the housing a rotor chamber which contains a motor-driven vertical-axis rotor to accept test tubes is disclosed. During operation, the test tubes are warmed by friction. To cool the centrifuge, cooling air is pulled in through openings in the lower side of the housing and upward into the rotor chamber by the fan action created by the rotation of the rotor. The air is guided out of the rotor chamber through an air exit in a direction of flow tangential to the perimeter of the rotor in a manner that ensures low turbulence and, thus, low noise. In particular, a slit-like air exit opening is arranged between the casing cover and the top side of the housing. In the annular gap between the rotor and the rotor chamber, an aerodynamically shaped displacement body is provided in a position at the side of the area of the air exit opening such that it directly follows the area of the air exit opening when viewed in the direction of rotation of the rotor. The displacement body is put on a molded part for attaching to the inside surface of the casing cover of the centrifuge such that the displacement body projects from the inside surface of the casing cover into the annular gap to thereby permit the cooling air to be guided out of the centrifuge with low turbulence and low noise.
