Abstract

(57) [Summary] [Structure] A plurality of holes 6 into which the capacitor 1 can be inserted are opened in the metal block 5 substantially in parallel, and the metal block 5 is joined to the heat absorbing surface 3 of the heat sink 2 to form each of the holes 6 described above. The grease compound 7 is applied to the inner wall of the capacitor 1, and the capacitor 1 is inserted into each hole 6. [Effect] Since the outer peripheral surface of the capacitor 1 is in contact with the heat absorbing surface 3 of the heat sink 2 through the grease compound 7 and the metal block 5, the heat of the capacitor 1 is quickly transferred to the heat absorbing surface 3 of the heat sink 2. .

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a capacitor mounting device.

[0002]

[Prior art]

 Conventionally, in space experiment equipment such as a small rocket, as shown in FIG. 2, a cylindrical capacitor 1 is adhered to a heat absorbing surface 3 of a heat sink 2 with a thermosetting resin adhesive 4 so that heat of a capacitor 1 is absorbed by the heat sink 2. It absorbs and suppresses the temperature rise of capacitor 1.

When a large number of capacitors 1 are required, another capacitor 1 is fixed on the capacitor 1 fixed on the heat sink 2 with a thermosetting resin adhesive 4.

[0004]

[Problems to be solved by the device]

 However, in the above-described capacitor mounting structure, since only a small part of the outer circumference of the cylindrical capacitor 1 is in linear contact with the heat absorbing surface 3 of the heat sink 2, the heat conducting area is small and the heat is not generated. Since it is difficult to propagate and there is no convection of heat in the universe where there is no air, heat is not radiated from the capacitor 1 to the space.

Therefore, when the capacitor 1 has a large capacity, there is a problem that the heat is not sufficiently dissipated and the reliability of the capacitor 1 is deteriorated due to the temperature rise.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a device for mounting a capacitor, which can improve the heat dissipation of a capacitor.

[0007]

[Means for Solving the Problems]

 According to the present invention, a metal block having a plurality of holes into which capacitors can be inserted is joined to the heat absorbing surface of the heat sink.

[0008]

[Action]

 In the present invention, the heat of the capacitor is transferred to the heat absorbing surface of the heat sink via the metal block that surrounds the entire circumference of the capacitor.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an outline of a device for mounting a capacitor according to the present invention.

A plurality of holes 6 into which the capacitor 1 can be inserted are opened in parallel in a metal block 5 made of a metal having a high heat conductivity, and the metal block 5 is bonded to the heat absorbing surface 3 of the heat sink 2 by a thermosetting resin. Join with a chemical agent.

The inner diameter of the hole 6 has an outer diameter slightly larger than the diameter of the capacitor 1.

A grease compound 7 (for example, a base material CASTALL S-1200, a curing agent SC-29) having excellent heat transfer properties and relatively high viscosity is applied to the inner wall of each hole 6 and then a capacitor is applied to each hole 6. 1 are respectively inserted so that the grease compound 7 is filled between the outer peripheral surface of each capacitor 1 and the inner side wall of the hole 6.

In the capacitor mounting device having the above structure, the heat generated in the capacitor 1 is transferred to the metal block 5 through the grease compound 7 filled between the outer peripheral surface of the capacitor 1 and the inner wall of the hole 6. Then, it is transferred to and absorbed by the heat absorbing surface 3 of the heat sink 2 through the metal block 5.

In this embodiment, the heat of the capacitor 1 is absorbed by the heat sink 2 via the grease compound 7 and the metal block 5, so that the heat dissipation of the capacitor 1 can be improved. .

Further, since the capacitor 1 can be attached to the heat sink 2 by fitting the capacitor 1 into the hole 6 provided in the metal block 5, it is possible to contribute to the efficiency of the mounting work of the capacitor 1.

It should be noted that the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention.
