Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat pipe mounting structure for a partition plate of heat exchange equipment, and more specifically,
The present invention relates to a heat pipe mounting structure suitable for mounting a plurality of heat pipes on a partition plate at high density.

[0002]

2. Description of the Related Art A conventional heat pipe mounting structure is, for example, as shown in FIG.
The heat pipe 1 is attached to the mounting holes 20 of the partition plate 2 on the heating side and the cooling side, and the flange 3 is fixed to the partition plate 2 with a plurality of bolts 6 via a seal member 4 made of packing or O-ring. Or, as shown in FIG. 4, a ring 5 having a threaded portion 51 on the outer periphery is attached to the heat pipe 1, the heat pipe 1 is passed through the attachment hole 20 of the partition plate 2, and the attachment hole 20 In some cases, the ring 5 is fixed by screwing the ring 5 into the threaded portion 21 in order to form it.

[0003]

However, the former of the above-described conventional heat pipe mounting structures, in which the flange is fixed to the mounting plate by a plurality of bolts, necessarily uses a flange having a large outer diameter. Therefore, there is a problem that a plurality of heat pipes cannot be arranged at high density. Further, since it is necessary to fix bolts at a plurality of points for one heat pipe, there is a problem that when arranging a plurality of heat pipes, it is extremely difficult to attach the heat pipe with a tool such as a spanner.

The latter of the conventional heat pipe mounting structures described above is capable of arranging a plurality of heat pipes at a high density, but since there is a gap between the male screw and the female screw of the mounting portion, the pressure resistance is high. It has poor properties and cannot completely block the heating side and the cooling side. Further, since the ring needs to be fixed to the heat pipe, when the ring is screwed into the mounting hole, it has to be screwed together with the heat pipe.

An object of the present invention is to solve the above-mentioned problems, to arrange a plurality of heat pipes at a high density, and to fix each heat pipe with high pressure resistance to a partition plate more easily. It is to provide a heat pipe attachment structure that can be performed.

[0006]

In order to solve the above-mentioned problems, a heat pipe mounting structure according to the present invention has a partition plate of a device provided with a mounting hole having an inward flange at a part of an inner periphery thereof, and is provided with a heating side. A heat pipe whose flange is fixed at a position separating from the cooling side is passed through the mounting hole in a state where the flange is in contact with the inward flange via a seal member, and the head is engaged with a screwdriver tool. A tubular male screw having a portion is provided in the other portion of the mounting hole, and is screwed into the screw portion. The engaging portion may have another structure, but it is preferable that the engaging portion has holes formed at equal angular intervals in the head end surface of the tubular male screw.

[0007]

According to the heat pipe mounting structure of the present invention, a tubular male screw is mounted in advance so that it can be slid onto the heat pipe, and the heat pipe is attached to the mounting hole of the partition plate via the seal member. The flange fixed to the heat pipe is pressed against the inward flange of the mounting hole through the seal member by passing the female thread portion in the direction in which it is provided and screwing the tubular male screw into the female thread portion. The heat pipe is attached to the partition plate.

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a partially omitted sectional view showing an embodiment of a mounting structure for a heat pipe according to the present invention. Figure 2
FIG. 3 is a perspective view showing a tool used for mounting the mounting structure of the heat pipe of FIG. 1.

The partition plate 2 of the equipment is provided with a mounting hole 20 having an inward flange 22 and a female screw portion 21 on the inner periphery thereof, and the mounting hole 20 with the heat pipe 1 penetrating therethrough. Passed through.

The heat pipe 1 has a diameter of 15.88 mm and a length of 10
It is a 17mm cylindrical container with both ends sealed.
A flange 3 made of steel and having an outer diameter of 38 mm is fixed to the heat pipe 1 at a position where the heating side and the cooling side are separated by brazing 31, and a large number of aluminum fins are provided on the left and right sides thereof. 11 and the fin 12 are attached. Fin 11 has an outer diameter of 25 mm, fin 1
2 has an outer diameter of 48 mm.

The heat pipe 1 is made of a steel material in which a screw 51 having an outer diameter of 42 mm is formed before the fin 12 is attached, and a tubular portion having an engaging portion 52 for engaging the screwdriver 7 shown in FIG. The male screw 5 is slidably attached, and then the fin 12 is attached to form the heat pipe 1 and the tubular male screw 5 as one set.

As shown in FIG. 1, the seal member 4 is attached to the left surface of the flange 3 of the heat pipe 1, and as described above,
From the right side of FIG. 1, the heat pipe 1 which is one set is passed through the mounting hole 20 of the partition plate 2, the tubular male screw 5 is screwed into the female screw portion 21, and the flange 3 is pressed against the inward flange 22. The heat pipe 1 is fixed to the partition plate 2.

The engaging portion 52 of the external thread 5 of this embodiment is composed of holes formed at 90 degree intervals on the head end face, and as shown in FIG. 2, the handle 73 and this handle 73 are provided.
A semi-annular base 71 fixed to the end of the base 71 and two pins 72, 72 projecting from one surface of the base 71 are used to use the screwdriver 7,
2 is inserted into two holes at symmetrical positions which form the engaging portion 52, and the handle 73 is held to screw the tubular male screw 5.

Since the mounting structure of this embodiment is constructed as described above, the mounting of the heat pipe is very simple, and the flange 3 can be constructed with a small diameter, so that the heat pipe can be attached to the partition plate 2. 1 can be mounted in higher density. Further, the heating side and the cooling side can be hermetically shut off from each other.

In the state shown in FIG. 1, the head portion of the engagement portion 52 of the tubular male screw 5 is replaced with the mounting hole 2 in the state shown in FIG.
The engaging portion may be configured so as to slightly project from 0, and the head portion may have a polygonal shape.

Further, the female screw portion 21 in the mounting hole 20 is formed directly on the inner surface of the mounting hole 20, but instead of this, a nut may be inserted and fixed in that portion.

It is preferable that the flange 3 is formed with a guide 32 projecting from the shaft core so that the seal member 4 can be easily mounted.

According to the present invention, the flange attached to the heat pipe is pressed against the inward flange of the attachment hole by screwing in one tubular male screw, so that the heat pipe can be attached very easily. Since it is not necessary to provide a plurality of bolt holes in the flange and the outer diameter of the flange can be reduced, a plurality of heat pipes can be arranged at a higher density. Moreover, since the flange is pressed against the inward flange of the mounting hole via the sealing material, the pressure resistance is high and the heating side and the cooling side can be airtightly shut off from each other.
