Claim:
1. Modular electronic system with convection cooling, comprising: a. a plurality of electronic modules, that each comprise an air inlet opening, an air outlet opening and an air space within the electronic module, wherein the air space is in air exchange with the air inlet opening and the air outlet opening; wherein b. at least one of the electronic modules is an electronic module to be cooled; c. one of the electronic modules is a first adjacent electronic module, which is adjacent to a first side of the electronic module to be cooled; and d. one of the electronic modules is a second adjacent electronic module, which is adjacent to a second side opposite to the first side of the electronic module to be cooled; wherein e. the electronic modules are designed in such a manner that air can enter into the first adjacent electronic module, generate an air stream for cooling within the air space of the electronic module to be cooled and exit heated from the second adjacent electronic module; and wherein f. the air stream is generated by natural convection by an increased temperature within the electronic module to be cooled and by a height difference between air inlet into the first adjacent electronic module and air outlet from the second adjacent electronic module; and g. the height difference is on average at least twice the height of a single electronic module.
