The invention belongs to the technical field of heat radiators, and relates to a heat radiator for a V type
fuel gas powering and compression integrated
machine. The heat radiator for the V type
fuel gas powering and compression integrated
machine disclosed by the invention is provided with a three-level heat radiating structure composed of heat radiating components, an air director (24) and an air
barrel (25), wherein the heat radiating components comprise a water radiator (20) and an air cooler (18) that are arranged up and down, a
shutter (17) is mounted in the front of the air cooler (18), a process gas inlet (13), a process gas outlet I (14), a process gas outlet II (11) and a process gas discharging opening (12) are formed in an air tank of the air cooler (18), an expansion water tank (21) is welded to the top of the air director (24), an expansion opening (8) and a water filling opening (9) are formed in the expansion water tank (21), and the air
barrel (25) is
barrel-shaped and is detachably mounted at the rear part of the air director (24). The heat radiator for the V type
fuel gas powering and compression integrated
machine disclosed by the invention can meet requirements of cooling both compressed fuel gas and cooling liquid, discharging the compressed fuel gas at an
overpressure, and providing fuel gas for the integrated machine.
