In the case where the units 2, 3, and 4 (hereinafter referred to as units) are mounted one on top of the other, a cooling fan 6 is provided at the bottom of the housing 1 to perform forced air cooling. After the cooling air passes through the lower unit 4 as shown by arrow 7, it enters the adjacent upper unit 3 and is discharged through each unit. Therefore, the flow velocity or flow rate of the cooling air in the unit mounted at the top is reduced, and the cooling capacity is significantly reduced due to the influence of heat generated from within the unit mounted at the bottom.

じた冷気を送れるようにしたものである。To this end, in order to effectively cool the heat generating part of electronic equipment, the present invention has developed an air intake duct that guides cooling air to the object to be cooled and an air intake duct on the side surface of the object to be cooled (L = knit) to guide cooling air to the object to be cooled. An exhaust duct is provided to exhaust air to the outside of the equipment, and the intake duct side is formed so that the cross-sectional area of the duct decreases from the intake section to the continuous section of the cooled object (a position far from the cold air intake fan). 1 On the other hand, the exhaust duct side is formed so that the cross-sectional area of the duct increases from the object to be cooled to the exhaust section, thereby equalizing the amount of cold air (air speed) sent to each object to be cooled (each unit). At the same time, it eliminates the influence of heat generation from other objects (units) to be cooled.Furthermore, the cold air inlet of each unit is provided with fins for adjusting the air volume for each mounted package, and the length of each fin is By appropriately selecting the angle and angle, it is possible to send cool air according to the amount of heat generated by the package.

．． When installed on the sides of 0 and 1.1, each unit is not affected by heat generation from other units, and by changing the cross-sectional area of the unit, the flow rate of cooling air can be adjusted to each unit. The relationship with the cooling air temperature is made appropriate, thereby allowing each unit to be cooled equally. Air volume adjustment fin 16 provided at the cold air introduction part of each unit
The function is to use the cooling air effectively by setting the air volume (wind speed) commensurate with the amount of heat generated by each package 14 mounted in the unit. That is, as shown in the figure, the length of the fins of the upper mesh cage t1 is increased to adjust the amount of cooling air. Of course, the angles of the fins may be changed.

It has the effect of increasing the cooling efficiency of equipment.
