Abstract

A modular mobile fract pump unit having for a radiator with a heat exchanger vertically for generally horizontal flow of air through the radiator and a duct provided on an air exit side of the heat exchanger to direct air exiting the heat exchanger upwardly. Preferably, the duct comprises a retractable duct for movement between an operative position for use in parked cooling operation and a storage position for transport of the unit as a road worthy vehicle, within the storage position the duct not increasing the overall width of the unit and in the operative position the duct extending laterally to the side of the unit beyond the storage position and increasing the overall width of the unit.

Claims

the first radiator mounted to the trailer on the first deck portion proximate the first side with the first heat exchanger adjacent the first side and with the first fan laterally inwardly of the first heat exchanger, the first fan providing for passage of air through the first heat exchanger horizontally and laterally outwardly toward the first side of the trailer,

the first radiator having a first duct member carried on the first radiator at a location laterally outwardly of the first heat exchanger and in the flow path of air from the first fan exiting horizontally and laterally from the first heat exchanger,

the first duct member movable relative to the first radiator from a storage position in which the first duct member does not extend laterally outwardly beyond the first side of the trailer and an operative position in which the first duct member extends laterally outwardly beyond the first side of the trailer,

in the operative position the first duct member receiving air passing laterally from the first heat exchanger and directing this air to exit vertically upwardly from a first duct outlet disposed along an upper edge of the first duct member,

the second radiator comprising a vertically extending second heat exchanger for passage of air horizontally therethrough to cool a fluid from the engine circulated within the second heat exchanger and a second tan to blow atmospheric air through the second heat exchanger,

the second radiator mounted to the trailer directly opposite the first radiator on the second deck portion proximate the second side with the second heat exchanger adjacent the second side and with the second fan laterally inwardly of the second heat exchanger, the second fan providing for passage of air through the second heat exchanger horizontally and laterally outwardly toward the second side of the trailer,

the second radiator having a second duct member carried on the second radiator at a location laterally outwardly of the second heat exchanger and in the flow path of air from the second fan exiting horizontally and laterally from the second heat exchanger,

the second duct member movable relative to the second radiator from a storage position in which the second duct member does not extend laterally outwardly beyond the second side of the trailer and an operative position in which the second duet member extends laterally outwardly beyond the second side of the trailer,

in the operative position the second duct member receiving air passing laterally from the second heat exchanger and directing this air to exit vertically upwardly from a second duet outlet disposed along an upper edge of the second duct member.

2. The unit as claimed in claim 1 wherein:

the first duct member extends vertically throughout the height of the first heat exchanger locating the first duct outlet at a height substantially the same as uppermost portions of the first heat exchanger, and

the second duct member extends vertically throughout the height of the second heat exchanger locating the second duet outlet at a height substantially the same as uppermost portions of the second heat exchanger.

3. The unit as claimed in claim 2 including:

a roof baffle member bridging laterally between the first radiator and the second radiator above the first fan and the second fan at a height below the first duct outlet and the second duct outlet,

the baffle member limiting the direct flow of air discharged upwardly from the first duct outlet and the second duct outlet downwardly into the first fan and the second fan.

4. The unit as claimed in claim 3 wherein:

a front air entrance way is defined between the first radiator and the second radiator below the roof baffle member for passage of atmospheric air rearwardly to the first fan and the second fan,

a rear air entrance way is defined between the first radiator and the second radiator below the roof baffle member for passage of atmospheric air forwardly to the first fan and the second fan.

5. The unit as claimed in claim 3 including at least one of:

a front air entrance way is defined between the first radiator and the second radiator below the roof baffle member for passage of atmospheric air rearwardly to the first fan and the second fan,

a rear air entrance way is defined between the first radiator and the second radiator below the roof baffle member for passage of atmospheric air forwardly to the first fan and the second fan,

a bottom air entranceway is defined for passage of atmospheric air from below the trailer upwardly through the trailer to the first fan and the second lint,

a first lower air entranceway is defined for passage of atmospheric air from below the first radiator from the first side laterally inwardly and underneath the first radiator to the first fan, and

a second lower air entranceway is defined, for passage of atmospheric air from below the second radiator from the second side laterally inwardly and underneath the second radiator to the second fan.

6. The unit as claimed in claim 2 including:

at least one first access door through the first duct member movable between a closed position and an open position, wherein with the first duct member in the storage position and the first access door in the open position the first access door providing access from the first side of the trailer to the first heat exchanger for cleaning; and

at least one second access door through the second duct member movable between a closed position and an open position, wherein with the second duct member in the storage position and the second access door in the open position the second access door providing access from the second side of the trailer to the second heat exchanger for cleaning.
