Abstract:
1. A cooling system for a rotary tablet press in which a rotor is driven by an electrical driving motor, the rotor and electrical driving motor are located in a closed housing, a control cabinet for electrical components being also enclosed by the closed housing, characterized in that a cooling machine is located within the closed housing, the cooling machine comprising a vaporizer ( 24 ), and a condenser ( 28 ), a vaporizer ( 24 ) of the cooling machine being a first part of a first heat exchanger, a second part ( 34 ) of the first heat exchanger being located in a cooling circuit for the electrical driving motor, the cooling circuit having a coolant, a first fan ( 44 ) is arranged in a channel being located in a passage ( 22 ) in the closed housing ( 10 ), the channel closed relative to a first remainder portion of the closed housing ( 10 ), the first fan received cooling air through an air entrance opening ( 48 ) of the closed housing ( 10 ), and transmits the cooling air through an air exit opening ( 52 ) of the closed housing ( 10 ), the cooling air being in heat exchange relationship with the condenser ( 28 ) of the cooling machine, the cooling circuit runs via an inner lying motor stator of the electrical driving motor integrated into the rotor ( 14 ), wherein a runner is connected to the rotor ( 14 ).
