Description

DETAILED DESCRIPTION OF THE INVENTION A.Objective of the Invention [Field of Industrial Application] The present invention relates to a heat transfer device that transports heat between heat receiving and dissipating parts using a heat transfer fluid circulating in a closed-loop sealed thin tube container. It relates to the structure of a heat exchange section (heat receiving section or heat radiating section). The present invention also relates to a new form of application of annular finned metal tubes such as finned tubes and bellows tubes, and the combination of thin tube containers and annular finned metal tubes of various shapes allows for various new types of heat exchange. section.

[Prior Art] As an example of a heat transfer device that transports heat between heat receiving and radiating parts using a heat transporting fluid that circulates in a closed-loop sealed thin tube container, the heat transporting fluid circulates by itself due to the temperature difference between the heat receiving and radiating parts. For example, the patent application filed by the inventor in 1986-15
No. 5747 and Japanese Patent Application No. 62-266265. Heat transfer devices that consume external energy and circulate heat transfer fluid include reactor cooling pipes and separate heat pipes (
(a type of closed-loop heat pipe). The present invention is not limited to any of them, but is applied to all heat receiving and dissipating parts of a heat transfer device constituted by a closed-loop type thin tube container made of thin tubes with an outer diameter of several tensile. Since the diameter is small, it is highly flexible, and since it is a closed loop type, there is no terminal part, so a unique heat receiving and dissipating part is required.

Since a thin tube container has an extremely high heat transfer coefficient during convection of a heat medium fluid, it is used as a heat receiving and dissipating part of a heat transfer device by forming a row of thin tubes to further increase the heat transfer coefficient and using natural convection or forced convection. It often forms a heat receiving and dissipating section using convection. In addition, the heat receiving and dissipating part using metal-to-metal heat conduction is often implemented by interposing a metal block with good thermal conductivity between the heat exchange object and the thin tube container. The target connection is carried out by sandwiching a large number of parallel thin tube containers under pressure between two metal blocks. 12th
The figure shows a flat power semiconductor cooling device as an example.

A group of parallel thin tubes in the meandering loop type thin tube container 21 are assembled in a predetermined row arrangement and placed in the forced convection air 25 to form a heat radiation section 21-C. Also, the heat receiving part 21-
H is a heat receiving metal block 22-1.22- in which a group of parallel thin tubes are used.
The amount of heat lost in the flat power semiconductor 24 is transferred to the heat receiving part 21-H by intermetallic heat conduction of the metal block. When the interval between the thin tube containers to be held is large compared to the thin tube diameter, each thin tube container is held in the groove group 23 provided in one or both of the metal blocks 22-L22-2 as shown in the figure. .

When the thin tube containers are held closely together, heat loss is small, so the groove group 23 can be omitted.

[Problems to be Solved by the Invention] The heat exchange section of the closed-loop capillary heat transfer device according to the prior art can cope with ordinary heat exchange almost without any problems by the above-described means. However, for large-capacity heat exchange, it is impossible to satisfy the requirements with only the tiered arrangement of thin tube container groups, and the installation of fin groups is often required. In such a case, the thin tube container is highly flexible and cannot withstand the pressure applied when the fins are attached. In addition, since it is a closed loop type, as shown in Fig. 12, two thin tube containers for the outward and return routes of the heat transfer fluid always form a set including the U-shaped bent pipe part, and the fin group is attached to each set. It is necessary to carry out the Therefore, it is impossible to install the conventional fin group structure. An even bigger problem is that thin tube containers have a small diameter, so in order to prevent fin efficiency from deteriorating, it is necessary to reduce the outer diameter of the fins (instead, it is necessary to increase the number of fins installed. This is not practical from an economic point of view). .

In addition, as for the structure of the heat receiving and dissipating part using heat conduction between metals, the structure shown in Fig. 12 is suitable for a single large-capacity heat exchange object, but it is suitable for a composite body in which the target heat receiving and dissipating part has many small capacities. In this case, it is necessary to manufacture a large number of metal blocks, which is uneconomical. It is also possible to implement this method by mounting a large number of small-capacity semiconductors on a large metal block, but this increases the weight of the metal block, which poses a problem.

B6 Structure of the Invention [Means for Solving the Problems] In the present invention, as a means for improving economical efficiency among the above-mentioned problems, we focus on fin tubes and bellows tubes, which are finned structures that are commercially available in large quantities and at low prices. At the same time, we attempted to integrate them with the thin tube container using a new form of application that had not been considered at all in the past. In addition, as a means to improve fin efficiency, we devised a new structure in which a fin structure is shared by multiple thin tube containers.

FIG. 1, FIG. 2, and FIG. 3 illustrate the basic structure of the heat exchange section of the heat transfer device according to the present invention. In each figure, (a) is a plan view, and (b) is a side view.

Reference numeral 1-1 in each figure represents a set of two thin tube containers each having an outward path and a return path formed by changing the circulation direction of a heat transfer fluid at a U-shaped bent tube portion b-1. 1-2 is another 1 of similar outbound and return trips
&112 thin tube containers.

In each figure, 2 is a metal tube with an annular fin, and examples of the metal tube include a finned tube in which a large number of annular fins are driven into a metal tube, a spiral fin tube in which spiral fins are integrally formed by rolling, and a thin-walled metal tube. Grooved metal tubes include processed bellows tubes and corrugated tubes. The structure of the heat exchange section according to the present invention is such that the thin tube container and the finned metal tube as described above are integrated by a predetermined means, and there are three predetermined coupling means. Figures 2 and 3 show the respective coupling means. Figure 1 shows the basic structure of the first means.
In the cross-sectional view (a) and longitudinal cross-sectional view (b) of the figure, at least one
More than one pair of outgoing and incoming thin tube containers 1-1.12 are inserted in close contact with each other. In the figure, 3 is the thin tube container 1
-1°1-2 is a metal tube (or spring) for pressurizing and tightly contacting the inner wall of the metal tube. The number of sets of thin tube containers to be inserted is determined by the inner diameter of the finned metal tube, and the greater the number of sets, the better the fin efficiency will be.

Figure 2 shows the second means, which is a thin tube container 1-1゜1-2.
is wound around the outer periphery of the finned metal tube 2 between the fins. In the figure, a case is shown in which a U-turn is made by winding a half circumference at the circulation direction changing part of the heat transfer fluid, but the winding angle is not limited to 180 degrees. Further, when the fin is a spiral fin, it is possible to wrap it in any number of turns, and it is possible to wrap it in any part. In the figure, the thin tube container has two sets and the number of fins is six, but the number of sets and number of fins is not particularly limited, but one finned metal tube 2 has more fins at intervals that can obtain appropriate fin efficiency. A set of may be arranged. Further, it is desirable that the outer diameter of the capillary container and the fin spacing match, or that the capillary be tightly clamped in a fitted state. In order to further reduce the contact thermal resistance and to prevent loosening, solder bonding is used between the thin tube container 1-1, 1-2 and the finned metal tube 2. Figures (a) and (b) in FIG. 3 show the third means, and the thin tube containers 1-1 and 1-2 are only inserted into the fin gaps. This means is used when it is desired to avoid an increase in pressure loss in the circulating flow of the heat transfer fluid due to the winding. In this case, since the contact length between the thin tube container and the fins is short, it is desirable that the two be inserted in a press-fit state.If the cross-sectional shape of the thin tube container is elliptical or rectangular, the contact thermal resistance can be further reduced. I can do it. Furthermore, when the contact thermal resistance is to be reduced and when it is necessary to prevent loosening, solder bonding is used in combination.

[Function] The capillary heat transfer device in which the finned metal tube and the capillary container as described above are combined and integrated has the following functions.

(al) Attaching the fin group is extremely easy and can be done quickly.

(bl) Since the outer surface and inner wall surface of the finned metal tube can be freely selected as heat receiving and radiating surfaces, a wide heat exchange area can be obtained.

FC) Appropriate fin efficiency can be obtained by adjusting the number of thin tube containers combined with the finned metal tube, and an effective heat transfer device can be constructed.

(dl) When constructing a large-capacity heat transfer device by forming a large number of meandering loop-type thin tube containers, the heat receiving and discharging section, which tends to become cluttered due to the tangle of many thin tube containers, is organized.

(e) Metal tubes with fins are manufactured in large quantities at low cost in various structures, and can be easily made by hand in the market, making it possible to construct an inexpensive heat exchange section.

Due to the above-mentioned functions, all the problems encountered in forming a large capacity heat exchange section of a thin tube container according to the prior art are solved.

[Example] The first example illustrated in the fourth recess plan view of the first example is an example in which the first means in the basic structure is applied as a means for connecting the finned metal tube and the thin tube container. In this embodiment, a thick-walled pipe having grooves capable of holding the thin tube containers upright is used as the metal tube 3 for tightly pressurizing and pressurizing the three sets of thin tube containers 1-1, 1-2, and 13. be. The metal tube 3 has the thin tube containers 11, 12.1-3 brought into close contact with the inner wall of the finned metal tube under pressure, and is also press-fitted into the inner wall surface. In the example shown in the figure, grooves are also provided on the inner wall side, so the finned metal tube 2 and the thin tube container 1-1
．． The ITs 2, 1-3 and the pressurizing metal tube 3 are all thermally coupled and integrated. The grooves may be provided only on the inner wall of the pressurizing metal tube 3 or the finned metal tube 2. The gaps created in such cases are filled with a thermally conductive filler to prevent an increase in contact thermal resistance. The pressurizing metal tube 3 does not necessarily have to be a tube and may be a metal rod. In such an embodiment, the contact thermal resistance between the capillary container and the tube inner wall is much lower than in the basic structure, improving the efficiency of the heat exchange section.

Second Embodiment The second embodiment shown as an example is also an embodiment in which the first coupling means is applied to the fifth recess surface in the same way as the first embodiment.

In this embodiment, the grooves of the pressurizing metal tube (or round bar) are omitted to simplify the structure. Inner walls of pressurizing metal tube 3 and finned metal tube 2 and thin tube container 1-1.1-2
．． A group of metal wires (or metal thin tubes) having an outer diameter approximate to that of the thin tube container is inserted under pressure into the gap created between the three elements 1-3, and brought into contact with the inner wall of the finned metal tube 2 and the pressurizing metal tube. It is rare. Note that the remaining voids are filled with thermally conductive filler 5.
is filled. In the second embodiment, the contact thermal resistance between the finned metal tube and the thin tube container is slightly inferior to the first embodiment, but it is improved compared to the basic structure example. This embodiment can be implemented more easily than the first embodiment.

Third Embodiment When heat exchange is carried out by arranging the heat exchange parts of the first and second embodiments in the forced convection of the heat transfer fluid, the metal tube is heated at each fin gap of the annular finned metal tube. Heat exchange efficiency is increased by providing at least one through hole at an arbitrary position, avoiding the thin tube container, from the outer peripheral wall surface to the inner wall surface of the inner metal tube press-fitted into the metal tube. I can do it. The effect of the through hole in the third embodiment is shown in the partially enlarged sectional view of FIG. In the figure, a through hole 6 reaching the inner wall surface of the pressurizing metal tube 3 is provided in each fin gap of the annular finned metal tube 2, and the through hole 6 is provided so as to avoid the thin tube container 1-1.

As shown by the arrow, the heat transfer fluid is sucked by the forced convection passing through the fin gaps and flows inside the pressurizing metal tube. Acts as a thermal surface. In addition, the flow of the heat medium fluid sucked out from the through holes 6 improves the flow near the base of the fin, where the flow is poor only by convection outside the tube, and also helps generate turbulent flow within the fin gap, thereby improving heat exchange efficiency. .

Fourth Embodiment When the second means of the basic structure is implemented as a means of connecting the annular finned metal tube and the thin tube container, in a normal fin structure, the winding angle is 27.
The limit is around 0 degrees. Therefore, when increasing the heat exchange capacity by providing a wrapping angle larger than that, it becomes possible to freely select the wrapping angle by using spiral fins as the annular fins. FIG. 7 is a side view showing such a fourth embodiment. In the figure, the capillary container 1-1 is 36
The thin tube container 1-2 is wound so that it moves straight after 0 degree winding, and the thin tube container 1-2 is wound so that it goes back to its original direction after 540 degree winding. An increase in the wrapping angle increases the heat transfer ability, but at the same time increases the pressure loss within the container of the heat transfer fluid, increasing the temperature difference between the heat receiving and dissipating parts. It is necessary to take the difference into consideration when making a decision. spiral fin tube 2
-2 When winding using 2. When connecting one set of thin tube containers to the same annular finned metal tube, the winding should be carried out by shifting the parts up and down, or two tubes should be wrapped for each set of thin tube containers. It is carried out using a circular finned metal tube.

Fifth Embodiment FIG. 8 is a schematic plan view showing the fifth embodiment. The thin tube container in this embodiment is formed into a meandering loop shape with many turns, and is constructed by providing a group of many heat receiving parts 1-H and a number of groups of heat radiating parts i-c. In the figure, the thin tube container is shown by a single line to simplify the drawing. The heating means H is a heat generating plate that heats the group of heat receiving parts 1-H of the thin tube container by sandwiching them in parallel. The heat dissipation means C in the figure is forced convection of refrigerant fluid. The thin tube containers pulled out from the heating means H are inserted or wound around the fin gaps of the annular finned metal tube 2-1 at both ends of the heat dissipation section 1-C, and the outbound and return container groups of the heat transfer fluid The thin tubes are arranged in two rows and in multiple stages to form a heat radiating section of the heat transfer device according to the present invention. Although any other means can be used as such alignment means, when the annular finned metal tube and the thin tube container group are thermally connected as in this example, the heat dissipation area is also expanded. You can. If it is desired to further expand the heat dissipation area, the number of annular finned metal tubes may be increased. In FIG. 8, it is also possible to use the refrigerant fluid as a heating heat medium fluid, use the rows of thin tube containers as the heat receiving section, and use the heating means section in the figure as the low temperature section.

Sixth Embodiment In the sixth embodiment illustrated in the partial sectional view of FIG. 9, a heat transfer fluid shown by an arrow flows through the annular finned metal tube 2, Thin tube container 1-C
(or 1-H) can be attached to the fin or metal tube surface within the fin gap.
Or 1-H) is a heat exchange part of a capillary heat transfer device in which a structure in which the heat exchanger is closely wound or inserted is used as a coupling means. The heat exchange section serves as a cooling device when the heat medium fluid is a low temperature fluid for cooling, and serves as a heating device when the heat medium fluid is a high temperature fluid for heating. In such a heat exchange section, the efficiency is particularly good when the heat transfer fluid is a liquid and the flow rate thereof is high. In the figure, (A) shows a finned tube 2 as an annular finned metal tube 2.
2 shows an example in which a bellows tube 2-2 is used, and (b) shows an example in which a bellows tube 2-3 is used. In the case of fin tubes, the fin pitch is formed to be small, so it is suitable for forming a large-capacity heat exchange section by combining a large number of thin tubes. In the case of bellows, the pinch is large, but the metal tube body is thin, and the thin tube container 1-C (or 1-H)
Since it is possible to bring the heat transfer fluid and the heat transfer fluid close to each other, it is possible to form a heat exchange section with a rapid thermal response.

Seventh Embodiment As shown in the plan view of FIG. 10, the seventh embodiment combines a group of ring-shaped finned metal tubes 2-'R consisting of a large number of short tubes with a plurality of sets of forward and return narrow tube containers. This is a heat exchange section using forced convection heat transfer of a heating medium fluid. The number of fins of the ring-shaped metal tube 2-H is at most 10 or less, and the thin tube container 1-C (or 1-H) to be coupled thereto
There are at most three sets or less of round-trip containers. This number and number of sets means that the length of the ring-shaped metal tube is not longer than about 30 to 40 pieces, and in the main heat exchange section, the surface of the ring-shaped fin group and the inside and outside of the metal tube are used as the heat transfer surface for forced convection. The entire wall surface is used, and the ring-shaped metal tube is preferably a short tube in order to generate turbulence due to the edge of the metal tube and to allow the heat transfer fluid to flow through the tube. 10 in the figure
-1.10-2 is a support supporting the direction change portion of each container in the group of thin tube containers 1-C (or 1-H).

A long finned metal tube may be used instead of the strut. Such a heat exchange section can provide a large heat transfer area compared to those with other structures.

Eighth Embodiment In the seventh embodiment, at least one through hole is provided in each fin gap of the ring-shaped metal tube at an arbitrary position that penetrates the tube wall of the metal tube and avoids the thin tube container. facilitates the flow of the heat transfer fluid in the ring-shaped metal tube, facilitates the flow of the heat transfer fluid in the fin gaps, and promotes the generation of turbulence between them, thereby increasing the heat exchange efficiency of the heat exchange section. Improve. Although the eighth embodiment is not particularly illustrated, the effect of the through hole is exactly the same as the effect of the through hole 6 in the plan view of the sixth recess, and the heat transfer fluid flows as shown by the arrow to expand the heat transfer area. It also encourages the generation of turbulence.

Ninth Embodiment The ninth embodiment illustrated in the partial cross-sectional side view of FIG. 11 is a heat exchange section according to the present invention having a structure in which heat is transferred by intermetallic heat conduction. Reference numerals 1-1 and 1-2 are sets of thin tube containers for the forward and return trips, respectively, and both are thermally coupled to a group of annular finned ring-shaped metal tubes 2-R. As shown in the cross-sectional view, a metal stopper 7 made of a metal with good thermal conductivity is press-fitted into the inside of each ring-shaped metal tube 2-R.

It is desirable that the inner wall of the ring-shaped metal tube and the metal stopper be in close contact with each other so that the thermal resistance value is close to zero. One end surface of the metal stopper 7 is formed as a heat receiving/dissipating plane 7-1, and is formed into a smooth surface with a shape convenient for bringing it into close contact with a heat exchanged body to transfer heat. The heat exchange section as described above can exchange heat with any object to be heat exchanged by metal-to-metal heat conduction using the metal stopper 7 as a heat exchange medium. This is particularly convenient when the ring-shaped metal tubes 2-R are disposed in a narrow gap within the range into which the group can be inserted to transfer heat. In FIG. 11, heat is absorbed from the group of heating elements (semiconductor element packages 8 in the figure) mounted on the boards in the narrow gaps between the boards in the group of printed circuit boards 9 in the device, and the heat is absorbed inside the device. This figure shows an example of application in the case of preventing a temperature rise. The heat receiving and dissipating plane 7-1 of the metal stopper 7 is thermally connected to the heat dissipating plane of the semiconductor element package 8 by adhesion using a thermally conductive adhesive or by adhesion using a low temperature brazing method. The other side of the capillary container set 1-1, 1-2, which is not shown in FIG. -2, and is transported by a heat transfer fluid and discharged from the heat radiation type heat exchange section to the outside of the device.

Tenth Embodiment In the ninth embodiment, it may be difficult to adhere the heat receiving and dissipating plane 7-1 of the metal plug 7 inside the device to the heat exchange object due to the structure thereof. In such a case, the metal stopper 7 and the inner wall of the ring-shaped metal tube 1-H are formed in a removably slidable state, and the metal stopper 7 is
The structure may be such that the ring-shaped metal tube 2-R of the heat exchange section is inserted and attached last after being adhered to the heat exchange object in advance.

When configured in this way, the heat receiving and dissipating plane 7- of the metal plug 7
1 does not necessarily have to be a flat surface, and can have any structure capable of being thermally connected to a screw structure and its ground heat exchanger. Although such a tenth embodiment is convenient for insertion and attachment, the contact thermal resistance value between the ring-shaped metal tube 2-R and the metal plug body 7 is increased compared to the ninth embodiment.

C6 Effects of the Invention The structure of the heat exchange section of the capillary heat transfer device according to the present invention makes it possible to easily and inexpensively form a fin structure for a closed-loop capillary container, which has heretofore been considered difficult and uneconomical. Make it familiar. This improves the performance of closed-loop capillary heat transfer devices, such as closed-loop capillary heat pipes, and expands their field of application. Further, the structure of the heat exchange section according to the present invention provides a new range of application and structure for annular finned metal tubes such as various fin tubes and bellows tubes, and provides a new fin structure.
