What is claimed is: 1. A mainframe cooling structure comprising: a body, said body comprising a hollow base and a side cover covering one side of said hollow base, said side cover having a ventilation grille for letting air in and out; a circuit board fixedly mounted inside said body, said circuit board comprising an electronic device that produces heat when operating; and a cooler module fastened to said circuit board and adapted to dissipate heat from said electronic device, said cooler module comprising heat sink means attached to said electronic device, a fan holder provided at a top side of said heat sink means, a first fan mounted in said fan holder and aimed at a first part of said ventilation grille and adapted to induce currents of air toward said heat sink means, and a second fan mounted in said fan holder and aimed at a second part of said ventilation grille and adapted to induce currents of air in direction reversed to the currents of air induced by said first fan for dissipating heat away from said heat sink means. 2. The mainframe cooling structure as claimed in claim 1, wherein said fan holder comprises a first locating frame, which is covered over said heat sink means and carries said first fan, and a second locating frame, which extends from said first locating frame at one side and carries said second fan. 3. The mainframe cooling structure as claimed in claim 1, wherein said cooler module further comprises second heat sink means provided at a bottom side of said second fan. 4. The mainframe cooling structure as claimed in claim 1, wherein said body is the mainframe of a touch screen display. 5. The mainframe cooling structure as claimed in claim 1, wherein said body is the mainframe of a computer. 6. The mainframe cooling structure as claimed in claim 1, wherein said electronic device is a CPU (central processing unit). 7. The mainframe cooling structure as claimed in claim 1, wherein said electronic device is a north/south bridge chip. 8. The mainframe cooling structure as claimed in claim 1, wherein said ventilation grille of said side cover is pressed on said first fan and said second fan.
