Description

  The present invention is directed to a heat transfer device for releasing heat transferred from a heating element, that is, a heat transfer device for cooling.

  The cooling heat transfer device receives heat from the heating element and stores the refrigerant in a vacuum state at both ends or in the vicinity of the heat transfer frame for storing the refrigerant, or both ends or the vicinity thereof and an intermediate position between them. In addition, a plurality of heat pipes in which the refrigerant rises and descends are extended in a communicating state, and the plurality of heat pipes are connected laterally or obliquely by a plurality of heat cooling fins. Is the basic configuration.

  In the above basic configuration, the temperatures inside the walls and cavities of the plurality of heat pipes differ depending on the distance from the heating element.

  In order to reduce such a difference as much as possible, for example, as shown in Patent Documents 1 and 2, in a state where they are connected to the tops of the plurality of heat pipes and the inner cavities communicate with each other. A structure in which one heat pipe is installed in the lateral direction is adopted.

  However, no special technical consideration has been given to the connection state of the plurality of heat pipes extended to the upper side and one heat pipe laid horizontally.

  Specifically, brazing is almost always used in the connection in the prior art.

  Therefore, the tops of the plurality of heat pipes are designed to project upward from the lower side wall of the one heat pipe, and are fixed to each other by the protruding portion and the lower side wall.

  Incidentally, in Patent Document 1, it is described that the boiling cooling pipe 3 and the fins 6 functioning as a heat pipe are brazed (paragraphs [0026], [0027], and [0027]. [0029]), such brazing is also adopted in the connection between a plurality of heat pipes, that is, the boiling cooling pipes 3 and the communication pipes 5 that are one heat pipe laid horizontally in the upper side. There is.

  Further, with respect to the refrigerant vessel 25 described in FIG. 15 and paragraph [0046] of Patent Document 1, the plurality of condenser sections 26 are in a state in which the ends thereof are projected, and the brazing is adopted. Is backed up.

  Therefore, in FIG. 1 of Patent Document 1, a cross-sectional view is shown in which the tops of the plurality of boiling cooling pipes 3 do not project to the lower side wall of the communication pipe 5, but the illustration shows the above protruding state. It's just omitted.

  On the other hand, in the partial cross-sectional front views shown in FIGS. 3 and 9 of Patent Document 2, the tops of the plurality of refrigerant pipes 10 extend from the lower side wall of one heat-dissipation-side header block 20B that is horizontally installed. It protrudes and objectively supports the brazing state as described above.

  Then, as shown in Patent Documents 1 and 2, when each of the top portions projects from the lower side wall portion, the condensed and liquefied refrigerant is generated in the one laterally installed heat pipe. However, it is inevitable that the water will be stored in the region of the lower side wall portion surrounded by the protruding top portion.

  However, as a result of such storage, a considerable amount of the liquefied refrigerant is transmitted along the inner wall surfaces of the plurality of heat pipes and cannot be dropped to the lower side, which in turn cools the plurality of heat pipes. There is a problem of reduced function.

  The refrigerant thus condensed and liquefied accumulates its storage sequentially, and the height level of the storage reaches the height level of the protrusion at the top, and as a result, the refrigerant is transmitted along the inner wall surfaces of the plurality of heat pipes. Then, it is attributed to continuing until it reaches the lower side.

  Needless to say, the aforementioned obstacles associated with such continuation are obviously negative in the original cooling function of the cooling heat transfer device.

  However, the related art does not propose a specific technical configuration for avoiding the failure accompanied by the continuation.

JP-A-8-340189 JP, 2003-166793, A

  The present invention improves the connection state between a plurality of heat pipes extending in the upper direction and one heat pipe laid in the lateral direction, so that the heat pipe is condensed and liquefied in the one heat pipe. An object of the present invention is to provide a configuration in which the refrigerant immediately drops downward along the inner wall surface of each of the plurality of heat pipes to promptly perform a normal cooling function.

In order to solve the above problems, the present invention is based on a reference configuration such as the following (1) and a basic configuration of the following (2).
(1) Both ends of or near one or a plurality of heat diffusion frames for storing a refrigerant which receives heat from a heating element and stores a refrigerant in a vacuum state and which is extended in the lateral direction, or At least one end or the vicinity thereof and a plurality of heat pipes in which the refrigerant rises and / or descends are extended in communication from an intermediate position between both ends in an upward direction, and a plurality of heat pipes are radiated between the heat pipes.

  In the present invention, which is based on the reference configuration and the basic configuration, since each of the top portions does not project from the lower side wall portion of one heat pipe horizontally installed, the inner side surface of the lower side wall portion is uneven. By forming a flat state not accompanied by the above, the refrigerant condensed and liquefied in the one heat pipe is quickly cooled when the one heat pipe is laid horizontally. Can be dripped downward along the inner wall of each of the plurality of heat pipes.

  As a result, a plurality of heat pipes exert their original cooling function quickly from the beginning of use even in a substantially uniform temperature state, and prevent the harmful effects of the storage of condensed and liquefied refrigerant as in the case of the conventional technology. can do.

  Further, each one refrigerant rising heat pipe and one refrigerant lowering heat pipe are provided, and the one heat pipe is sequentially lowered from the upper end of the refrigerant rising heat pipe to the upper end side of the refrigerant lowering heat pipe. In the case of being inclined to, the refrigerant smoothly flows from the refrigerant rising heat pipe to the one heat pipe side, and smoothly descends from the one heat pipe to the refrigerant lowering heat pipe.

The manufacturing process of the heat exchanger for cooling which concerns on the said basic structure is shown, and all (1), (2), (3) is showing the top view, (4), (5) shows each. Figure 3 shows a perspective view from a combination of plan views.

  In the reference configuration and the basic configuration, as shown in FIGS. 1 (a), 1 (b) and 1 (c), each of the plurality of heat pipes 2 extending in the upper direction is connected to the top and In the state where the cavities of 1 are communicated with each other, one heat pipe 2 is installed in the horizontal direction along the horizontal direction. However, each of the tops projects from the inner wall of the lower side of the one heat pipe 2. The structure which is not provided is adopted, and as a result, the inner wall forms a flat state without unevenness.

  For this reason, as described in the section of the effect, when the one heat pipe 2 is horizontally installed, the condensed and liquefied refrigerant does not protrude in the heat pipe 2. It is possible to descend along the inner walls of the plurality of heat pipes 2 via the top.

The connection structure in which the respective tops do not protrude from the lower inner wall can be realized by molding or welding based on a predetermined dimensional design.
The structure in which the one heat pipe 2 is installed in an inclined state instead of in the horizontal direction will be described later with reference to FIG.

FIG. 1 (a) shows an embodiment of the reference configuration, in which the tops of the plurality of heat pipes 2 and the one heat pipe 2 are in an intersecting state. In the case of the embodiment, the refrigerant that has risen in the plurality of heat pipes 2 collides with the upper side wall portion of the one heat pipe 2 that is installed in the lateral direction, so that the refrigerant flows slightly laterally and Even if the heat pipe 2 at the position is mixed with the ascending refrigerant, the amount of the mixing is not large at all.
The black circles in FIGS. 1 (a), 1 (b) and 1 (c) indicate the refrigerant inlet 20.

  1 (a), 1 (b), and 1 (c) show an embodiment in which the heat pipe 2 extending upward is provided at both ends and the intermediate position thereof, the heat pipe 2 extending upward is 2 It is also possible to adopt a configuration in which the heat pipe of the present invention is extended to both ends or the vicinity thereof, or one end or the other end of the intermediate position and both ends or the vicinity thereof, and the embodiment of FIG. Has been adopted.

  As in the embodiment shown in FIGS. 1A, 1B, and 1C, when the one heat pipe 2 is installed horizontally, the refrigerant is condensed in the heat pipe 2. At the stage of liquefaction, the original heat pipe 2 must be lowered.

  That is, even if one heat pipe 2 is installed in the horizontal direction, there is a tendency that the refrigerants rising and falling in the plurality of heat pipes 2 are mixed with each other and further the alternating current is extremely insufficient.

  1 (b) and 1 (c) show the end portions of the plurality of heat pipes 2 as the transverse cross sections of the heat pipes 2 located at both ends become the upper side near the top. The embodiment of the basic configuration is characterized in that the heat pipes 2 are sequentially expanded in the opposite direction, and the heat pipes 2 are sequentially expanded on both sides as the cross section of the heat pipe 2 at the intermediate position becomes the upper side.

  In addition, in FIG. 1B, the cross-sections of the plurality of heat pipes 2 increase at the same rate as the upper side near the top, and the lower side surface of the wall near the top is increased. FIG. 1C shows an embodiment characterized by forming a slanted shape by a straight line, and FIG. 1C shows a cross section in the lateral direction sequentially as the cross section of the plurality of heat pipes 2 becomes the upper side near the top. The embodiment is characterized in that the lower side surface of the wall portion near the top portion forms a curved shape by increasing the degree of expansion.

  In these embodiments, the refrigerant that has risen in the plurality of heat pipes 2 smoothly flows in the lateral direction and flows into the heat pipe 2 that is installed in the lateral direction, and as a result, the adjacent position is increased. It can be attributed to the fact that the refrigerants rising from the heat pipe 2 in FIG.

  In particular, as shown in FIG. 1C, in the case of an arched shape in which the ratio of the increase in the lateral cross section increases toward the upper side in the vicinity of the top of the heat pipe 2, the refrigerant smoothly rises. It is possible to change from a directional to a lateral flow.

  In the plurality of heat pipes 2, the region in which the transverse cross section is sequentially enlarged in the vicinity of the top portion also corresponds to the lower side wall portion of the one heat pipe 2 installed in the lateral direction.

  FIG. 1B shows an embodiment in which a flat surface exists as the lower side wall portion of the one heat pipe 2, while FIG. 1C shows an embodiment in which such a flat surface does not exist. ..

Of the plurality of heat pipes 2, the two heat pipes 2 at both ends do not necessarily have to be linear in the upward extending direction, and have a curved shape as shown in FIG. 1 (b). Can be
Further, in the reference configuration and the basic configuration, as shown in FIG. 1A, one or a plurality of heat pipes are provided at intermediate positions other than the tops of the plurality of heat pipes 2. It is also possible to adopt an embodiment characterized in that 2 is extended in the lateral direction and connected to the plurality of heat pipes 2 (note that in FIG. 1A, one heat pipe 2 is The embodiment extended laterally is shown.).
Even in the heat pipe 2 extending in the lateral direction, the lower side surface of the wall portion near the connection portion with the plurality of heat pipes 2 is formed by a straight line as shown in FIG. 1 (b). By adopting the configuration of forming the oblique shape and the configuration of forming the curved shape as shown in FIG. 1C, it is possible to realize the smooth mixing of the refrigerants.

Regarding the arrangement of the heat-releasing fins 3 connected to the plurality of heat pipes 2 extended to the upper side, as shown in FIG. As shown in FIG. 1C, the heat-dissipating fins that connect between the heat pipes of the plurality of heat pipes 2 are arranged so as to form a bent or curved surface. 3, another heat radiation fin 3 that further connects the heat radiation fins 3 to each other is provided in the up-down direction, and one heat pipe 2 erected on the upper side and a refrigerant storage Any of the arrangement states in which the thermal diffusion frame 1 is connected can be adopted.
In the case of the embodiment adopting the arrangement state shown in FIGS. 1 (b) and 1 (c), heat cooling is performed as compared with the case of the embodiment adopting the arrangement state shown in FIG. 1 (a). By setting the surface area of the fins 3 to be large, the cooling effect can be further promoted.

  One fin 3 for heat radiation is provided on both outer sides and / or laterally of two heat pipes 2 extending vertically from both ends of the heat diffusion frame 1 for storing the refrigerant or in the vicinity thereof. In the case of the embodiment characterized in that a plurality of heat-releasing fins 3 are connected to the upper side of the heat pipe 2 (not shown), the heat-releasing cooling connected to the both outer sides. The cooling fin 3 and the heat-releasing fin 3 connected to the upper side can promote the cooling effect in the two heat pipes 2 and the one heat pipe 2, respectively.

In the reference configuration and the basic configuration, as shown in FIG. 2, it is possible to select a configuration in which two heat diffusion frames 1 for storing a refrigerant are extended along the lateral direction, one on the upper side and the other on the lower side.
In the above configuration, the heating element 4 can be inserted between the upper and lower connecting portions.

As for the heat spreader frame 1 for storing refrigerant in the reference configuration and the basic configuration, as shown in FIG. 3A, the width in the vertical direction is set to be large, and then the two-dimensional mesh is arranged in the vertical direction and the horizontal direction. It is also possible to adopt an embodiment in which the heat capacity absorbed by the heat source is set large by stretching 21.
In the case of the above embodiment, as shown in FIG. 3B, by attaching the planar heating element 4 to the surface of the two-dimensional mesh 21, efficient and quick heat conduction can be realized. it can.

  The respective wall portions of the heat diffusion frame 1 for storing the refrigerant and the heat pipe 2 contribute to cooling like the fins 3 for cooling heat, and the amount of heat radiated per unit area is the fin 3 for cooling heat. Is almost the same as.

In the reference configuration and the basic configuration, focusing on the heat radiation effect of the surface of the heat pipe 2,
Inside the cavities of the plurality of heat pipes 2 and / or the one heat pipe 2 and / or the heat diffusion frame 1 for storing a refrigerant and / or the one or more heat pipes 2 extending in the lateral direction. An embodiment in which a two-dimensional mesh 21 having a shape stretched in each cross section orthogonal to the longitudinal direction of the cavity is extended along the longitudinal direction, or
A cavity from the inner wall of the plurality of heat pipes 2 and / or the one heat pipe 2 and / or the heat diffusion frame 1 for storing a refrigerant and / or the one or more heat pipes 2 extending in the lateral direction. It is possible to employ an embodiment in which the convex portion 22 having a shape protruding in each cross section orthogonal to the longitudinal direction is extended along the longitudinal direction.

  Due to the stretched structure having the shape of the two-dimensional mesh 21 and the protruding structure having the shape of the convex portion 22, the inside area in contact with the refrigerant is increased in the cavity, and as a result, the heat for storing the refrigerant is increased. It is possible to promote the cooling effect through the diffusion frame 1 and the wall portions of each heat pipe 2.

  FIG. 4A shows an embodiment in which the shape of the two-dimensional mesh 21 in each cross section orthogonal to the longitudinal direction of the cavity in the heat storage frame 1 or the heat pipe 2 for refrigerant storage is extended along the longitudinal direction. 4 (b), 4 (c), and 4 (d) show the shape of the convex portion 22 in each cross section orthogonal to the longitudinal direction in the cavity from the inner wall of the refrigerant-diffusing heat diffusion frame 1 or the heat pipe 2 in the longitudinal direction. 2B shows an embodiment extending along the direction, FIG. 2B shows a state of a protrusion 22 having a rod-shaped cross section, and FIG. 2C shows a protrusion 22 having a planar cross-section. 2D shows the shape according to FIG. 2D, and FIG. 2D shows the shape according to the state where the convex portion 22 is extended to the center position of the cavity.

  FIG. 5 shows that one refrigerant rising heat pipe is extended in a concatenated state from one end of or close to the refrigerant storage heat diffusion frame, or from an intermediate position of both ends to the above refrigerant storage heat diffusion frame. From the other end of the frame or in the vicinity thereof, one refrigerant lowering heat pipe is extended in a concatenated state, and the lower side surface of the horizontal heat pipe extends from the upper end of the refrigerant rising heat pipe to the refrigerant lowering heat pipe. The embodiment of the said reference structure and the said basic structure characterized by being installed in the inclined state which becomes a lower position one by one toward the upper end of a pipe is shown.

  For example, in each of the embodiments shown in FIGS. 1, 2, and 3, the upper heat pipe 2 in the horizontal direction is laid horizontally, and as a result, the heat pipe 2 extending in the upper direction is a refrigerant. However, the so-called gas-liquid mixed state may occur and the smooth rise of the refrigerant vapor may be hindered to some extent.

  On the other hand, in the case of the above-described embodiment, the refrigerant vapor rises in the refrigerant rising heat pipe 2 on one side and the refrigerant liquid descends in the refrigerant lowering heat pipe 2 on the other side, so that the refrigerant storage The refrigerant is sequentially circulated through the heat diffusion frame 1.

As a result, an efficient rise of the refrigerant vapor can be realized, and thus an efficient cooling can also be realized.
In FIG. 5, the refrigerant rising heat pipe 2 extends upward from the intermediate position of both ends of the refrigerant storage heat diffusion frame 1, but by extending to such an intermediate position, heat is released. Since the space for extending the cooling fins in the horizontal direction is from the intermediate position to the one side end and it is not necessary to extend further from the one side end to the lateral side, a compact design can be realized. ..

  FIG. 6 shows two refrigerant lowering heat pipes 2 extending in an upward direction from both ends of the refrigerant storage thermal diffusion frame 1 or in the vicinity thereof, and the two ends of the refrigerant storage thermal diffusion frame 1 are connected to each other. From the middle position of the above, one refrigerant rising heat pipe 2 is extended in a connected state, and the lower side surface of the horizontal heat pipe 2 extends from the upper end of the refrigerant rising heat pipe 2 to the refrigerant lowering heat pipe. 2 shows an embodiment of the reference configuration and the basic configuration, which are installed in an inclined state such that the position gradually lowers toward the upper end of 2.

  In the case of the above-described embodiment, as a result of providing the heat pipes 2 for lowering the refrigerant on both sides, as compared with the embodiment shown in FIG. 5, more efficient circulation of the refrigerant and efficient cooling of the heating element 4 are realized. be able to.

  FIG. 7 shows that two refrigerant rising heat pipes 2 are extended in an upward direction from both ends of the refrigerant storage thermal diffusion frame 1 or in the vicinity thereof, and both ends of the refrigerant storage thermal diffusion frame 1 are connected to each other. From the middle position to the upper side, one heat pipe 2 for lowering the refrigerant is extended in a connected state, and the lower side surface of the heat pipe 2 in the horizontal direction extends from the upper end of the heat pipe 2 for raising the refrigerant to the heat pipe for lowering the refrigerant. 2 shows an embodiment of the reference configuration and the basic configuration, which are installed in an inclined state such that the position gradually lowers toward the upper end of 2.

  In the embodiment shown in FIG. 7, the refrigerant ascending heat pipe 2 and the refrigerant descending heat pipe 2 are reversed from the embodiment shown in FIG. 6, but as in the case of the embodiment shown in FIG. It is possible to circulate various refrigerants.

  As in the case of the embodiment shown in FIG. 3A, the heat-diffusion frame 1 for storing refrigerant shown in FIG. 6 employs a two-dimensional mesh 21 having a predetermined gap, and is shown in FIG. 3B. Similar to the embodiment, the planar heating element 4 can be attached to the surface of the two-dimensional mesh 21.

On the other hand, the thermal diffusion frame 1 for storing a refrigerant shown in FIG. 7 adopts the two extended constructions on the both sides, that is, the upper side and the lower side in the lateral direction, and in the case of the embodiment of FIG. Similarly, a plurality of heating elements 4 can be inserted between the upper and lower connections.
It should be noted that only one heating element 4 is attached when the heating element 4 is attached as shown in FIGS. 3B and 6 and when it is inserted as shown in FIGS. 2 and 7. Instead, a plurality can be targeted.

  When the heating element 4 and the refrigerant descending heat pipe 2 are close to or adjacent to each other, in the lower region of the refrigerant descending heat pipe 2, there is a hindrance to the descending of the refrigerant, and a sufficient circulation action is exhibited. I can't.

  In consideration of such a point, in each of the embodiments shown in FIGS. 5, 6 and 7, a predetermined distance is set between the heating element 4 and the refrigerant descending heat pipe 2.

  In particular, as shown in FIGS. 5, 6 and 7, an embodiment characterized in that a heat insulating region 5 is arranged between the lower region of the heat pipe 2 for lowering the refrigerant and the region where the heating element 4 is present. When adopting, it is possible to prevent the heat generated from the heating element 4 from being directly transmitted to the lower region of the refrigerant descending heat pipe 2 by the heat insulating region 5.

In addition, as shown in FIGS. 5, 6 and 7, when the heat insulating region 5 is joined to the refrigerant descending heat pipe 2 along the vertical direction, it is possible to sufficiently prevent the heat generated from the heating element 4 from being transferred. This makes it possible to contribute to smooth circulation of the refrigerant.
As shown in FIGS. 5 and 6, the heat insulating region 5 adopts either a structure in which the periphery is simply surrounded by the wall 51, or a structure in which the wall 51 and the heat insulating material 52 are housed inside. can do.
