Modular electronic
system 1 with
convection cooling, comprising a plurality of
electronic modules 10, 20, 30, that each comprise an air inlet opening 12, 22, 32, an air outlet opening 14, 24, 34 and an
air space 11 within the electronic module 10, 20, 30, wherein the
air space 11 is in
air exchange with the air inlet opening 12, 22, 32 and the air outlet opening 14, 24, 34, wherein at least one of the
electronic modules 10, 20, 30 is an electronic module to be cooled 10, one of the
electronic modules 10, 20, 30 is a first adjacent electronic module 20, which is adjacent to a first side 16 of the electronic module to be cooled 10 and one of the electronic modules 10, 20, 30 is a second adjacent electronic module 30, which is adjacent to a second side 18 opposite to the first side 16 of the electronic module to be cooled 10, wherein the electronic modules 10, 20, 30 are designed in such a manner that air can enter into the first adjacent electronic module 20, generate an air
stream 11 for cooling within the
air space 11 of the electronic module to be cooled 10 and exit heated from the second adjacent electronic module 30.
