ABSTRACT:
A cooling system for an IC tester achieves an optimum temperature control in a sealed box type housing. The cooling system includes a sealed housing, a board rack for mounting a plurality of circuit boards horizontally, a back board mounted perpendicular to the floor of the sealed housing for controlling the air flow around the circuit boards wherein the back board is positioned at around the center of the sealed housing in such a way that a continuous air flow passage is formed between the back board and inner walls of the sealed housing so that the air flows circulate around the back board, a cooling tube connected to a heat exchanger in order to circulate cooling medium, a plurality of small sized fans forming a horizontal air passage between the heat exchanger and the boards within the sealed housing so that the temperature difference among the boards is minimized.
