Description of the Related Art In a conventional plate heat pipe, a metal flat plate 3-2 having a concave surface portion and a metal flat plate 3-1 are hermetically laminated and bonded as illustrated in a schematic sectional view 10 and a schematic plan view 11. In general, the concave portion is formed as a sealed plate-shaped container 6 in which a predetermined amount of hydraulic fluid is enclosed to form a plate-shaped heat visor. Reference numeral 7 is a supporting pillar for reinforcement. In practical use, various wicks are often formed on the inner wall surface of the plate-shaped container 6 to give a capillary action.

た。The conventional plate-type heat pipe constructed as described above has the problems that it cannot be used in the top heat mode and the performance in the horizontal heat mode is deteriorated, like the ordinary heat pipe. Further, the fact that the strength of the hydraulic fluid applied to the flat plate surface against the internal pressure is small has been a serious problem. That is, when the working temperature range of pure water is 80 ° C or less, the saturated vapor pressure of the working solution is small, so it is not a big problem. On the other hand, there is a risk that the plate plane may be deformed due to an increase in saturated vapor pressure. In order to prevent this, it is necessary to make the plate sufficiently thick, which causes problems such as an increase in heat resistance and an increase in weight. If the ambient temperature drops below zero, it is necessary to use a low temperature hydraulic fluid, and the low temperature hydraulic fluid generally has a saturated vapor pressure several times or a dozen times that of pure water. In order to increase the pressure resistance of the plate heat pipe, it is necessary to significantly increase the thickness of the plate, and the increase in weight due to this has been a serious problem in practical use.

It is sandwiched by 3-4 and is hermetically adhered to the inner surface thereof by the brazing filler material 10. Reference numeral 9 is a spacer for preventing the brazing material from flowing out during brazing. Since this heat pipe container is a thin tube with an outer diameter of 2 mm and an inner diameter of 1.2 mm, it has extremely high pressure resistance, and even in the case of a pure copper thin tube container or an aluminum thin tube container, it is 100 kg / c.
It had a strength capable of easily withstanding an internal pressure of m 2 or more, and could sufficiently reduce the thickness of the plate.

There are three types: −318949 (loop type thin tube heat pipe), Japanese Patent Application No. 2-319461 (loop type thin tube heat pipe), and Japanese Patent Application No. 3-61385 (micro heat pipe). In JP-A-63-318493, both ends of a meandering thin tube heat pipe are rotatably connected to each other to form an endless loop, and check valves are provided at a plurality of predetermined positions in the loop, so that the hydraulic fluid is It excels in top heat mode characteristics because it is a form in which the amount of heat is conveyed by circulating it in a predetermined direction. In Japanese Patent Application No. 2-319461, the check valve in the loop is omitted, and the amount of heat is conveyed by both the axial vibration of the hydraulic fluid and the circulation of the hydraulic fluid in an unspecified direction. Suitable for transportation. Japanese Patent Application 3-61
385 is a non-loop type, the container does not form a loop, and the amount of heat is carried only by the axial vibration of the hydraulic fluid, which is suitable for thinning and downsizing, and has excellent reliability.

犠牲にせざるを得ないことを意味する。(A) The performance of the meandering thin tube heat pipe is improved as the number of turns of the meandering in the same plane of the plate is increased. Especially, the performance in the top heat mode is the performance in the bottom heat mode. It is experimentally known that 30 turns or more are required in a 100 mm width experimentally in order to operate well without much difference. However, the radius of curvature of the thin tube container is, for example, about 1.5 times the outer diameter of the tube at the center line as the minimum limit in the case of a pure copper thin tube. Eg 1
In order to hold a meandering thin tube having an outer diameter of 3 mm in a 00 mm width, it is necessary to connect the tubes at a pitch of 9 mm, and the maximum number of holding tubes is about 11 turns. That is, in order to exert good performance irrespective of the holding posture, it is necessary to sandwich and embed a three-layer meandering thin tube container. This means that the minimum plate thickness is about 13 mm, which means that the performance must be sacrificed to construct a plate having a thickness smaller than that.

ている。(C) In order to further improve the performance, it is desired to reduce the contact thermal resistance between the meandering thin tube heat pipe and the sandwiching metal flat plate. The contact between the metal flat plate and the meandering thin tube container is a line contact or a broken line contact, and the filling adhesion with the brazing material for reducing the contact thermal resistance increases the weight of the plate heat pipe and lowers the thermal response performance. I am busy.

There is no choice but to rely on difficult manual work at high temperatures. In addition, mass production is difficult and cost inevitably increases. Due to these factors, although the plate heat pipe meets the needs of the industry, it is delayed in practical use except for special purposes. Cost reduction by mechanization and automation of plate type heat pipe manufacturing work is becoming an urgent issue. The present invention solves each of the problems (a), (b), (c), and (d).

A series of meandering lengths that meander at a predetermined depth, a predetermined width, and a predetermined pitch on a predetermined bonding surface of a predetermined unit thin plate 1 of a plate that is a laminated structure of metal thin plates 1 and 3 having good thermal conductivity. The narrow groove 2 is formed, and the meandering groove is either an endless loop type in which both ends thereof are connected or a non-loop type in which both ends are not connected,
A plurality of the unit thin plates are stacked on top of each other, or a unit thin plate and a flat thin plate on which a narrow groove is not formed are stacked on top of each other. A predetermined number of layers having a long and narrow closed tunnel 4 are formed.

構成される。A predetermined amount of a predetermined heat pipe hydraulic fluid is enclosed in the closed tunnel to form a loop type meandering thin tunnel heat pipe having the same internal structure as the loop type meandering thin tube heat pipe or the non-loop type meandering thin tube heat pipe. It is configured as a non-loop type meandering small-diameter tunnel heat pipe, and the circular equivalent diameter of this small-diameter tunnel is that the hydraulic fluid enclosed in the tunnel always closes the inside of the tunnel due to its surface tension, and it can be used in any holding posture. It is configured to have a diameter that is sufficiently thin so as to circulate or vibrate in the axial direction of the tunnel while maintaining this closed state.

厚さは１／２と大幅に改善される。The plate type heat pipe constructed as described above exhibits the following actions. (B) The meandering small-diameter tunnel heat pipe that can be built in can reduce the radius of curvature of the turn portion to the utmost limit. In other words, it becomes possible to connect at a high density with a pitch that is only the width of the narrow groove plus about 1 mm of the width of the groove, and a tunnel heat pipe with many turns can be built in. Therefore, it is possible to construct a plate-type heat pipe with high performance and thin thickness. As an example, outside diameter 3mm inside diameter 2
When a tunnel heat pipe is built in instead of the mm meandering thin tube heat pipe, a tunnel with a diameter of 2 mm can be built in with a pitch of 3 mm, and a plate type with a thickness of 5 mm in which 33 pieces are arranged in a 100 mm width. It becomes possible to configure a heat pipe, and the number of built-in tubes is three times
The thickness is greatly improved to 1/2.

Since the lamination plate does not require so much strength, it can be made thin, and the weight of the adhesive and the filler for sandwiching and bonding will be zero. It will be possible.

The meandering fine grooves can be formed by automatic cutting, batch forming by electric discharge machining, batch forming by high pressure press, etc. All of them are easy to automate and do not require machining time, Precision processing is easy. In addition, the stacking process also uses a large-scale heat treatment furnace to perform batch mass stacking,
It can be easily carried out by stacking by semi-automatic heat treatment by a continuous heat treatment furnace. Both processes are easy processes for mass production at low cost. Therefore, in mass production, a significant cost reduction can be achieved.

In this example, the thin groove surfaces of and are laminated so as to face each other. In this case, the meandering small-diameter tunnel 4 has a circular cross-sectional shape, which is advantageous in that unnecessary resistance is less likely to occur when the working fluid circulates and vibrates. In FIG. 3, two unit thin plates 1-1 and 1-2 and a flat thin plate 3 constitute a two-layer meandering small-diameter tunnel 4. Fig. 4 also shows two unit thin plates 1-

There are cold plates, heat transport ribbons that take out heat from the narrow gaps between mounted parts, and cool it down.
As an application example of the point where the temperature of the entire plate rises due to some heating, (b) there is a heat diffusion plate for cooling the heating element, which is powerful and compact and difficult to dissipate heat. There is also a heat treatment plate, and by applying elastic properties as the material of the plate, it is possible to apply (d) as a detachable thermal connection ribbon, (e) as a detachable cold plate, etc. Another advantage of the present invention is that it is expected to bring about an epoch-making cost reduction as compared with a plate-type heat pipe with a meandering thin tube heat pipe. This is because the process can be constituted by only two steps, and any of the steps is a step that mass production is easy and automation is easy.
