Title: Cooler for electronic apparatus
Inventor: TAKAGI NOBUYOSHI
IPC: H05K7/20
Filed: 1992-12-21
Abstract: PURPOSE:To make uniform temperature distribution between boards in cooling of an apparatus by dividing a plurality of printed boards in response to power consumption, and so disposing the boards that power consumption corresponds to air flow rate distribution of a cooling fan. CONSTITUTION:Overall air flow rate distribution characteristics of a fan chassis 3 are so formed that a central air flow rate has a large crest shape. At the stage of finishing a design of a board, power consumption is obtained at each printed board 2. Various components such as IC, etc., are mounted on the board 2. An IC of high integration such as a gate array, a CPU, etc., has high power consumption. Accordingly, the board 2 in which many such ICs are mounted has high power consumption. The board 2 having high power consumption is collected at a central part so that the obtained power consumption of each board 2 corresponds to an air flow rate distribution of a cooling fan 5, and the board 2 having low power consumption is disposed toward both ends. Thus, when the boards are so disposed as to correspond to the air flow rate distribution, uniform temperature distribution is obtained between the boards.
