Abstract

PURPOSE:To control amount of cold air passing through a vacant slot or individual electronic circuit packages, by providing a guide pin on each electronic circuit package for pushing an L-shaped arm to rotate the same so that air resistance is regulated by a guide vane. CONSTITUTION:When a slot is vacant and no electronic circuit package is inserted therein, a guide vane 1 is turned to the transverse position by tension of a spring 3 to close the passage of cold air. When a package 9 is inserted into the slot, a guide pin 11 pushes a rod 15 of an L-shaped arm 4 to rotate the same and the guide vane 1 is thereby turned to the vertical position to open the passage of cold air. The side edge of a fan type plate 14 engaging the guide vane 1 takes various positions according to rotational angular positions of the L-shaped arm 4. Accordingly, passage condition or amount of cold air can be regulated by changing the position of attaching the guide pin 11.

(Prior Art) Conventionally, as shown in FIG. 3, the air cooling structure of this type of electronic device has an electronic circuit package 2 equipped with a plurality of integrated circuits.
The front 22 of the cage 2 is held in the housing 27 so that the printed boards of the cage 21 are parallel to each other.
They were inserted into the housing and arranged side by side, and had a structure in which forced air cooling was performed using cold air from a cooling fan 23 at the bottom of the housing. Integrated circuits mounted on printed boards have various external shapes, and are usually mounted in various shapes, such as those with heat sinks. In addition, in the conventional cooling structure described above, the electronic circuit pancage 21 is not necessarily inserted into all the slots 22 of the cage 28, and if there is an empty slot, the cool air does not pass through the package 21 side and is inserted into the slot 22 of the cage 28. In order to prevent the air from escaping through the empty side of the electronic circuit package, a dummy package 24 having the same shape as the electronic circuit package is inserted into the empty slot to make the air resistance of the empty slot the same as that of other parts of the electronic circuit package. The air flow path has been blocked by attaching the airflow path to a flat plate or inserting a flat blocking plate 25 into the blocking plate holder 26.

(Problem to be Solved by the Invention) The conventional electronic circuit cooling structure described above has difficulty in cooling the electronic circuit package due to differences in the size, number, presence or absence of a heat sink, and other shapes of the integrated circuits mounted on the electronic circuit pancase. Since the ventilation resistance to cold air differs depending on the type of electronic circuit puff cage, when multiple electronic circuit pan cages are lined up and cooled by sending cold air, the amount of cold air flowing varies depending on the electronic circuit package, causing a problem that the cooling temperature varies.

A package guide 10 is provided to connect a front panel 7 and a back panel 8 that form part of a housing of an electronic device, and an electronic circuit package 9 is attached to the front panel 7 along this package guide 10.
It is inserted into the back panel 8 side from the side. A cooling fan 12 is provided at the bottom of the housing, and plate-shaped guide vanes 1 for guiding cool air upward are attached to the front panel 7 and the bank panel 8 by shafts 2 on the side edges. The guide vane 1 is rotatable around the shaft portion 2. As shown, the guide vane 1 is located between the cooling fan 12 and the electronic circuit package 9, and although only one guide vane is shown in FIG. A plurality of them are provided corresponding to the slots. The cooling passage of the guide vane 1 is opened when its plate surface is parallel to the electronic circuit pancake 9, and the cooling passage is closed when its plate surface is perpendicular to the package 9. The side edge of the guide blade 1 opposite to the pivot side, that is, the tip of the blade 1 is connected to the front panel 7 via a first spring 3, and in the embodiment, the first spring 3 is a tension spring. The guide vanes 1 act in a direction perpendicular to the electronic circuit package 9, that is, in a direction to place them in a horizontal position, and in this state, they block the passage of cold air.

The I-shaped arm 4 according to the present invention has a pair of fixed plates 13 that are parallel to and opposite to the guide blade 1 in the upright position and are fixed to the bank panel 8. The fixing plate 1 is fixed by a pin 5 protruding from the lower edge of the plate part 14.
3 and can rotate around the pin 5. Here, when the L-shaped arm 4 rotates around the pin 5, the side edge of the fan-shaped plate portion 14 pushes up the guide blade 1 against the spring force of the first spring 3, and thereby It is designed to open a path for cold air. A second spring, that is, an arm biasing spring 6 is provided between one of the pair of fixing plates 13 and the tip of the fan-shaped plate portion 14 of the L-shaped arm 4. This arm biasing spring 6 acts to rotate the fan-shaped plate portion 14 in the horizontal direction, and the rotation of the fan-shaped plate portion 14 in the horizontal direction causes the guide blade 1 to be moved by the action of the first spring 3. Fold it horizontally,

A guide pin 11 is provided at the bottom of the back end of the electronic circuit pancage 9 in the insertion direction, and the electronic circuit package 9
When inserted into the package guide 10, the guide pin 11 comes into contact with the bar-shaped portion 15 protruding above the L-shaped arm 4, and the L-shaped arm 4 is pushed around the pin 5 against the arm biasing spring 6. and then rotate it to a position determined by the position of the guide pin 11. Due to this rotational movement, the side edge of the fan-shaped plate portion 14 of the L-shaped arm 4 pushes up the guide vane 1 into an upright position, opening a passage for cold air.
Conversely, when the electronic circuit package 9 is removed, the guide pin 1
1 no longer moves, the arm biasing spring 6 causes the fan-shaped plate portion 14 to fall down, and the first spring 3 causes the guide vane 1 to close the passage of cold air. The same applies when the electronic circuit package 9 is not inserted into the pan cage guide 10 from the beginning.

) When the electronic circuit package 9 is inserted into an empty slot, the guide pin 11 of the package 9 pushes the rod-shaped part 15 of the L-shaped arm 4 and rotates it, raising the guide vane 1 and opening a path for the cool air. . Depending on the rotation angle position of the L-shaped arm 4, the location of the side edge of the fan-shaped plate portion 14 that engages with the guide vane 1 changes, and the opening degree of the guide vane 1 changes accordingly. Specifically, as shown in Figure 2 (C) and (d), the package 9
By changing the mounting position of the guide pin 11, the angle at which the guide vane 1 stands up changes, making it easier for cold air to pass through.
The amount of cold air etc. is adjusted.

(Effect of the invention) As explained above, the present invention has a guide vane 1 that can be opened by an L-shaped arm 4, and a guide pin 1 that pushes and rotates an L-shaped arm 4 provided on an electronic circuit package 9.
1, when an empty slot into which the electronic circuit package 9 is not inserted is created, the guide vane 1 lies down and blocks the passage of cold air, which has the effect of eliminating the need for a dummy package or a blocking plate. Furthermore, even when the electronic circuit package 9 is inserted, by changing the position where the guide pin 11 is provided, the air resistance against cold air can be adjusted by changing the angle at which the guide cylinder I11 is erected. This has the effect of eliminating variations in the amount of cold air due to variations in temperature, making the temperature of the integrated circuit uniform, and providing stable operation. Furthermore, since the guide vane l is automatically moved by inserting and removing the electronic circuit package 9, there is no need for any special operation.
