Abstract:
1. An electronic apparatus comprising: a housing; first and second circuit boards disposed in the housing; and a pump block disposed between the first and second circuit boards, the pump block abutting a first electronic part mounted on the first circuit board and a second electronic part mounted on the second circuit board, the pump block being configured such that during operation input air is sucked in from outside the housing and heated air is discharged out of the housing such that neither the input air sucked in from outside the housing nor the heated air discharged out of the housing directly contacts the first and second circuit boards, in which the pump block includes a piezoelectric pump having a piezoelectric device and a pump housing, and in which the pump block further includes (i) a duct that houses the pump and has a fin protruding into the space that houses the pump, (ii) a first heat transfer member that is sandwiched between the duct and the first electronic part and in close contact therewith, and (iii) a second heat transfer member that is sandwiched between the duct and the second electronic part and in close contact therewith, and in which the duct has a plurality of protrusions each facing one of the first circuit board or the second circuit board and each having a flat top surface and a shape which is substantially the same as a respective one of the first electronic part or the second electronic part, and in which the first heat transfer member is sandwiched between one protrusion of the duct and the first electronic part and the second heat transfer member is sandwiched between another protrusion of the duct and the second electronic part.
