Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a mounting structure of a cooling device for a computer,
In particular, the invention relates to a mounting structure of a computer cooling device for preventing screws such as nuts for fixing a cooling plate from falling off.

(Prior Art) Conventionally, as shown in FIG. 4, a mounting structure of a cooling device for a computer is such that a heat radiating plate (see FIG. 3) is bonded to a pressure contact connector 5 mounted vertically on a board surface of a mother board 7. The package 1 is mounted, and the cooling plate 2 is attached to the bolt 1 in close contact with the cooling plate to cool the cooling plate.
1, and a cooling liquid is circulated from the hose 10 into the cooling plate 2.

It is necessary to hold and fix the cooling plate 2 separately from this so that a shear load is not generated on the bonding surface between the heat dissipation plate and the micropackage 1 due to the weight of the cooling plate 2. Therefore, a shaft 6 having male screw portions at a plurality of tips is fixed vertically to the mother board 7, the shaft 6 is projected through the hole of the cooling plate 2, and the compression coil spring 4 is press-fitted into the male screw portion at the tip of the shaft. The nut 3 is screwed and screwed in a specified amount, and the cooling plate 2 is elastically pressed by the spring, thereby preventing a shear load acting on the bonding surface between the heat dissipation plate and the micropackage due to the weight of the cooling plate. There is.

(Problems to be Solved by the Invention) In the above-described mounting structure of the cooling device for the computer, it is necessary to remove the cooling plate 2 for maintenance and replacement of the micropackage 1, and the special nut 3 is loosened so that the male screw end of the shaft 6 is loosened. Remove from At that time, a large number of special nuts 3 often get lost due to falling or the like, and replacement and repair took time. This has resulted in the operator being burdened with the task of storing the special nut for repair.

The present invention has been made in view of such a problem, and a computer of the type that prevents the screws such as nuts for fixing the cooling plate from falling off and also prevents the jigs that hold the screws from falling off. An object is to provide a mounting structure for a cooling device.

(Means for Solving Problems) In a mounting structure of a cooling device for a computer according to the present invention, a polygonal linear member and a polygonal vertex of the linear member are wound in a loop. A ring portion formed by the above, and a thread such as a nut attached to the linear member by fitting the groove into the ring portion and a groove formed on the circumference, and this nut and the like. A cooling plate which is fixed by screws and in which a refrigerant circulates, and a cooling hose which penetrates the polygonal frame of the linear member and is attached to the cooling plate to supply the cooling plate with the cooling hose, The linear member is configured to be suspended on the cooling hose when screws such as nuts are removed from the cooling plate.

(Example) Next, this invention is demonstrated about an Example with reference to drawings.

FIG. 1 is a perspective view of a nut falling prevention structure according to an embodiment of the present invention. The member for holding the nut is continuously formed by a linear member 8 such as a steel wire. In the illustrated embodiment, the member for holding the nut is formed in a substantially square shape, and wheels 8a are formed at the vertices, that is, the four corners. The special nut 3 is held in the ring 8a so as not to come off. In the illustrated embodiment, a portion of the outer circumference of the nut 3 has a small diameter, and the wheel 8a is rotatably fitted to this small diameter portion. A compression coil spring 4 is press-fitted into one end of the nut 3.

FIG. 2 is a perspective view showing a state in which the nut falling prevention structure according to the present invention is mounted on a computer. Also, in FIG.
It is a perspective view which shows the state which removed the cooling plate 2 for maintenance exchange of a micropackage. The micro package 1 to which the heat dissipation plate 9 is adhered is mounted on the pressure contact connector 5 mounted on the motherboard 7. In order to cool the micropackage 1 through the heat dissipation plate 9, a cooling plate 2 in which a refrigerant circulates is mounted on the heat dissipation plate 9, and the cooling plate 2 is closely attached to the heat dissipation plate 9 to improve heat transfer efficiency. There is. However, as described above, it is necessary to adopt a structure in which the weight of the cooling plate 2 does not apply a shearing force to the bonding surface between the heat dissipation plate 9 and the micropackage 1. Therefore, the shaft 6 fixed vertically to the mother board 7 (4
(Used in this case) protrudes through the holes provided at the four corners of the cooling plate 2. The special nut 3 is screwed into a male screw portion 6a provided at the tip of the shaft 6 via a compression coil spring 4 and is tightened so as not to loosen by utilizing elasticity of the spring. At this time, the linear member of the present invention is mounted while holding four special nuts 3 as shown in FIG. In this case, the cooling hose 10 is attached to the cooling plate 2 through the inside of the linear member.

To remove the cooling plate, first loosen all the special nuts 3 and remove them from the shaft 6. At this time, all of the special nuts 3 are held by the ring 8a of the linear member, and the linear member itself is held by the hose 10 for cooling.

Next, when the micropackage is replaced and the cooling plate is reattached, the shaft 6 is first inserted into the holes at the four corners of the cooling plate.
Through and tighten the special nut 3. At this time, since the special nut is held by the linear member, the work can be performed easily and quickly.

In the above description, the nut disengagement prevention structure according to the present invention is formed into a quadrangle by a linear member such as a steel wire, and four wheels are formed at the corners or vertices thereof. The number of rings can be increased or decreased by forming a polygonal shape. Also, the engagement structure of the linear member and the special nut,
Although the ring of the linear member and the small diameter portion of the special nut corresponding to the ring are used, other structures may be designed as necessary. Further, the linear member may be made of other metal or synthetic resin instead of the steel wire.

(Effects of the Invention) As described above, according to the present invention, when the cooling plate is removed, the screws such as nuts for holding the cooling plate are prevented from falling off, and the jig for holding the screws is also removed. The effect of preventing can also be achieved.
