In recent years, as such a radiator, a plurality of aluminum alloy materials have been laminated and pressure-bonded, and a small-diameter tunnel meandering at the lamination boundary surface has been formed by a roll bonding method. A plate type heat pipe used for a heat diffusion plate enclosing 134a or the like has been proposed (Japanese Patent Laid-Open No. Hei 10-185465). As shown in FIGS. 1A and 1B, this plate-type heat pipe 1 is obtained by laminating two metal thin plates 3 and 4 and joining them by hot rolling. The meandering small-diameter tunnel 2 is formed by inflating the shape of the boundary surface that has been applied and uncompressed, and the heat dissipation performance is improved by significantly increasing the number of meandering turns per unit width. It is to let.

However, the radiator using the conventional plate-type heat pipe as described above cannot cope with the situation in which the use of CFC-based refrigerants is restricted due to recent environmental problems. There are problems such as the heat dissipation efficiency not being able to keep up with the higher performance of the MPU. In addition, since the metal sheets are joined by hot rolling, the base material is greatly deformed, and the shape of the tunnel cannot be formed with high accuracy. In addition, the joining strength is reduced due to alloying between dissimilar metals on the joining surface. There are points.
In addition, uneven application of the anti-pressing agent occurs, so that the boundary between the press-bonding portion and the anti-pressing portion cannot be formed with high accuracy. However, there are also problems such as the inability to completely remove the water.

Copper alloys of the 000's, brass, free-cutting brass, tin-containing brass, Admiralty brass, Naval brass, aluminum bronze, white bronze, etc. can be used. From the viewpoint of heat conduction, pure copper is desirable. The thickness of the copper plate is 0.01
It is preferable to set it to 0.6 mm. If the thickness is less than 0.01 mm, sufficient strength and corrosion resistance cannot be obtained, and if the thickness exceeds 0.6 mm, the weight becomes too heavy. At least one of these metal plates is subjected to a thin-walled portion forming process such as pressing or rolling in a pattern corresponding to a predetermined-shaped pressure-bonding preventing portion to form a thin-walled portion having a predetermined shape. In the press working, a thin portion is formed on the metal plate by providing a convex portion corresponding to the thin portion of a predetermined shape in at least one press die, and in the rolling process, a thin wall of a predetermined shape is formed on at least one roll. A thin portion is formed on the metal plate by providing a convex portion corresponding to the portion and passing the metal plate between the synchronized rolls.

The activation process is performed as follows. That is, the copper plates 12 and 13 having at least one of the thinned portions processed are loaded into a vacuum chamber, and the copper plates 12 and
13 is one electrode A, which is grounded, and 10 to 1 × 10 −3 Pa between the electrode A and another electrode B which is insulated and supported.
The glow discharge is performed by applying an alternating current of 1 to 50 MHz in an extremely low-pressure inert gas atmosphere, preferably an argon gas, and the area of the electrode A exposed in the plasma generated by the glow discharge is equal to that of the electrode B. Less than 1/3 of the area of
A sputter etching process is performed. The inert gas pressure is 1
If the pressure is less than × 10 −3 Pa, it is difficult to perform stable glow discharge, and it is difficult to perform high-speed etching. If the pressure exceeds 10 Pa, the activation treatment efficiency decreases. If the applied alternating current is less than 1 MHz, it is difficult to maintain a stable glow discharge, and it is difficult to perform continuous etching. If the applied alternating current exceeds 50 MHz, oscillation tends to occur and the power supply system becomes complicated, which is not preferable. In addition, in order to perform etching efficiently, the area of the electrode A needs to be smaller than the area of the electrode B. When the area is set to 1/3 or less, etching can be performed with sufficient efficiency.

Thereafter, the two metal plates are laminated and joined as shown below. That is, the two parts are brought into contact with each other in such a manner that a gap is formed by the thin part formed on at least one of the copper plates 12 and 13 and the surfaces subjected to the activation treatment are opposed to each other, and they are superposed and cold pressed. Thereby, the press-fit preventing portion is formed in the thin portion, and the portion to be joined to be the joining portion is joined.

In this case, the lamination bonding can be performed at a low temperature and a low rolling reduction, and the adverse effects such as structural change, alloying, fracture, etc. are reduced in the metal plate and the lamination bonding as in the case of hot welding or high rolling reduction. Or it can be eliminated. Further, the deformation and extension of the hollow laminate can be suppressed to a low level, and the shape of the hollow portion can be accurately processed. Temperature T (° C.) of the metal plate at the time of this lamination joining
Is preferably 300 ° C. or lower. More preferably, the range is more than 0 ° C. and 300 ° C. or less. If the temperature is lower than 0 ° C., a large-scale cooling device is required. If the temperature is higher than 300 ° C., the joining portion is alloyed and the joining strength is undesirably reduced. The rolling reduction R (%) is preferably 30% or less. More preferably, the range is 0.1% to 30%. If it is less than 0.1%, sufficient bonding strength cannot be obtained, and if it exceeds 30%, deformation becomes large, which is not preferable in terms of processing accuracy.

Prior to the sputter etching process of the apparatus shown in FIG. 4, there is provided a process for forming a thin portion on a metal plate in order to form a gap corresponding to a press-fit preventing portion having a predetermined shape, and a hollow portion to be formed. By suppressing the crimping of the pattern portions of the above, a plate laminate of a laminated metal plate having a crimp preventing portion having a predetermined shape is obtained by laminating and joining the metal plates as described above using the apparatus shown in FIG. By expanding the press-blocking portion, a hollow laminate having a required hollow portion shape can be obtained. Note that a cutting step of cutting into a predetermined size may be provided instead of the winding roll section. In addition. In the processing step of forming the thin portion, the cross-sectional shape of the mold corresponding to the depression is not particularly limited, but may be a semicircle, an ellipse, a rectangle, a trapezoid, or the like. The depth of the depression is preferably 0.1 mm or more. More preferably, 0.
A range of 2 to 1 mm is good. When the thickness is less than 0.1 mm, the metal plate in contact with the roll in the hollow portion joins the other metal plate during lamination bonding, and the shape of the inflated tube is not constant. Although the depth of the depression exceeds 1 mm, there is no problem in use, but the processing cost for forming the depression increases. More preferably, it is 1 mm or less.

As described above, in the plate laminate of the present invention, at least one of a plurality of metal plates is formed with a thin portion (dent), and the metal plate having the thin portion and another metal plate are formed. After the surfaces of the plates facing each other are activated, the activated surfaces are brought into contact with each other so as to face each other, overlapped with each other, and cold-pressed at a low rolling rate to form a pressure-blocking portion in the thin portion. In the hollow laminate of the present invention, the press-blocking portion is expanded to form a hollow portion. Furthermore, the plate-type heat pipe of the present invention is one in which a heat pipe operating body is sealed in this hollow portion, and since water can be sealed as a heat pipe operating body instead of a CFC-based refrigerant, it is environmentally friendly and has a high radiation efficiency. Can be improved,
In addition, since a thin metal plate can be joined at a low rolling rate, it is possible to achieve high-precision shape and lightweight and thin shape.
