DIESEL LOCOMOTIVE COOLING DEVICE Russian patent published in 1995 - IPC

FIELD: railway transport. SUBSTANCE: device has fan units 3, each formed by panels of radiator 2 installed along wall of body 1 and centrifugal fan 4 communicating with panels of radiator 2 through air duct 5 in form of axially symmetric converging tube. Drive 9 of fan 4 has one working wheel 10 and it is coupled by tie-rod 8 with rolling members 6 installed in upper part of cooling device on cross guide 7 for travel relative to panels of radiator 2. Fan units 3 are arranged in rows behind panels of radiator 2 at sides of central aisle 11 in diesel locomotive engine compartment. Inner surface of air duct 12, limiting circuit of rotation of working wheel 10 of fan 4, is made to brachistochrone 13. When carrying maintenance and repair operations, to facilitate cleaning panels of radiator 2, dismounting and mounting radiator sections, fan units 3 on rolling members 6 can be shifted to central aisle 11 after disconnecting support post at base. Such displacement of fan units 3 provides access to panels of radiator 2 for maintenance and repair. Equation for plotting brachistochrone 13 is given in description of invention. EFFECT: facilitated maintenance and repair of cooling device. 2 cl, 2 dwg
