Abstract
To provide a cool wind to a heat exchanger for a supercharger powerful enough to cool it down on a construction machine, a cooler for a supercharger is mounted at the top of the stream on the flow of the cool wind and at the upper side of any other heat exchangers. A current plate is mounted under the cooler for the supercharger to regulate the flow of the cool wind that enters from air inlets and flows under the cooler for the supercharger, and to direct the cool wind into the cooler for the supercharger.
Claims20
A construction machine in which a plurality of heat exchangers including a supercharger heat exchanger is disposed in a building cover as a cooling unit, and air intakes are formed in an upper surface portion and a side surface portion of the building cover located upstream of the cooling unit in a cooling air flowing direction, wherein the plurality of heat exchangers in the cooling unit is arranged in such a manner that upstream side heat exchangers including the supercharger heat exchanger are disposed most upstream in the cooling air flowing direction and that the supercharger heat exchanger is disposed at a highest position among the upstream side heat exchangers, and a current plate is provided below the supercharger heat exchanger, the current plate regulating a flow of cooling air flowing in through the air intake located upstream of the supercharger heat exchanger in the cooling air flowing direction and toward below the supercharger heat exchanger to introduce the cooling air into the supercharger heat exchanger.
