1. An air compressor comprising:
an electric motor; a compressor adapted to be driven by the electric motor for generating compressed air; a pair of air tanks adapted to store the compressed air generated by the compressor, each formed into an elongated barrel shape, and disposed parallel to each other at an interval; an inverter control substrate on which an inverter module that makes up a control unit for the electric motor is mounted; a case for accommodating the inverter control substrate therein; a cooling fan adapted to generate cooling air so as to cool the compressor, the electric motor and the inverter module via the case; and a second cooling fan, wherein the inverter module is interposed between the inverter control substrate and a base of the case, the inverter module is mounted on an upper side of the inverter control substrate, and the base of the case positions on an upper side of the inverter module, wherein a surface of the inverter module is in directly close contact with the base of the case, wherein the base of the case extends substantially horizontally, wherein the inverter control substrate is parallel to the base of the case wherein the case is formed into a box shape so that an entirety of the inverter control substrate is accommodated therein, wherein the base of the case extends substantially in parallel to a flowing direction of the cooling air so that the cooling air flows along an external surface of the base serving as a cooling surface, wherein the cooling fan is mounted at one end of the electric motor and the second cooling fan is mounted at the other end of the electric motor, and wherein the base of the case extends horizontally from the cooling fan to the second cooling fan. |
