Description

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

  The cooler heat transfer device receives heat from the heating element, and stores the refrigerant in a vacuum state at both ends of the heat storage frame for storing the refrigerant or in the vicinity thereof, or at both ends or the vicinity thereof and an intermediate position thereof in the upward direction. In addition, a plurality of heat pipes in which the refrigerant rises and falls are extended in a connected state, and the plurality of heat pipes are connected in the lateral direction or the oblique direction by a plurality of heat-dissipating fins. Is the basic configuration.

  In the above basic configuration, the temperatures in the walls and the 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, the top cavities of the plurality of heat pipes are connected and the inner cavities are in communication with each other. A configuration 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 extending upward and one heat pipe extending in the lateral direction.

  In particular, brazing is employed in most cases in the connection in the prior art.

  For this reason, the tops of the plurality of heat pipes are designed to protrude upward from the lower wall part of the one heat pipe, and are fixed by the protruding part and the lower wall part.

  Incidentally, in Patent Document 1, it is described that the boiling cooling pipe 3 and the fins 6 exhibiting a function as a heat pipe are brazed (paragraphs [0026], [0027], [0027] [0029] Such brazing is also employed in the connection of a plurality of heat pipes, that is, the boiling cooling pipe 3 and the communication pipe 5 which is one heat pipe installed horizontally in the upper side. Yes.

  Furthermore, with respect to the refrigerant tank 25 described in FIG. 15 and paragraph [0046] of Patent Document 1, the plurality of condensing portions 26 are in a state in which the end portions protrude, and the brazing is adopted. Is backed up.

  Accordingly, 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 protrude from the lower wall part of the communication pipe 5, but the illustration shows the above protruding state. It is simply 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 tubes 10 are from the lower side wall of one heat-dissipation-side header block 20B installed in the horizontal direction. It protrudes and objectively supports the brazed state as described above.

  Thus, as shown in Patent Documents 1 and 2, when each of the tops protrudes from the lower side wall, the refrigerant that has been condensed and liquefied in the one heat pipe installed in the lateral direction. However, it must be stored in the region surrounded by the protruding top portion of the lower side wall portion.

  However, as a result of such storage, a considerable amount of liquefied refrigerant cannot be dropped down along the inner wall surfaces of the plurality of heat pipes, and as a result, cooling in the plurality of heat pipes becomes impossible. The failure that the function deteriorates occurs.

  The refrigerant condensated and liquefied in this manner accumulates sequentially, and the height level of the storage reaches the height level of the protrusion at the top, and as a result, the refrigerant travels along the inner wall surfaces of the plurality of heat pipes. Therefore, it is attributed to continuing until it reaches the lower side.

  Needless to say, the obstacle with such a continuation is clearly negative in the original cooling function of the cooling heat transfer device.

  However, the prior art does not propose a specific technical configuration for avoiding the failure with the continuation.

  The present invention condenses and liquefies in the one heat pipe by improving the connection state between the plurality of heat pipes extending in the upper direction and one heat pipe extending in the lateral direction. It is an object of the present invention to provide a configuration in which a normal cooling function is quickly exhibited by the refrigerant immediately falling downward along the inner wall surface of each of the plurality of heat pipes.

  In order to solve the above-mentioned problems, the basic configuration of the present invention is to receive one or a plurality of refrigerants that receive heat from the heating element, accommodate the refrigerant in a vacuum state, and extend in the lateral direction. A plurality of heat pipes in which the refrigerant rises and / or descends in an upward direction from both ends of the heat diffusion frame or the vicinity thereof, or at least one end or an intermediate position between the vicinity and both ends, A heat exchanger for cooling, in which the heat pipes are connected by a plurality of heat cooling fins, connected to the tops of the plurality of heat pipes and in communication with the inner cavities. In the horizontal direction, one heat pipe is erected, and the top portion is composed of a heat exchanger for cooling which is in a state where the top portion does not protrude from the inner wall on the lower side of the one heat pipe.

  In the present invention based on the basic configuration, since each top portion does not protrude from the lower wall portion of one heat pipe installed in the lateral direction, the inner side surface of the lower wall portion is accompanied by unevenness. By forming a flat state, the refrigerant condensed and liquefied in the one heat pipe can be quickly transferred from the tops to the plurality of refrigerants when the one heat pipe is installed horizontally. It can be dripped downward along the inner wall of each heat pipe.

  As a result, multiple heat pipes exhibit their natural cooling function from the beginning of use in a substantially uniform temperature state, and prevent adverse effects caused by the storage of condensed liquid refrigerant as in the case of the prior art. can do.

  Further, each of the one refrigerant rising heat pipe and the refrigerant lowering heat pipe is 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. The refrigerant smoothly flows from the refrigerant raising heat pipe to the one heat pipe and smoothly descends from the one heat pipe to the refrigerant lowering heat pipe. Based on the circulation, quick cooling can be realized.

It is a front view showing the basic configuration, (a) shows an embodiment in which the plurality of heat pipes intersect with the one heat pipe at the top, (b), An embodiment in which the cross section in the lateral direction increases linearly in the vicinity of the tops of the plurality of heat pipes, and (c) shows the vicinity of the tops of the plurality of heat pipes extending upward. In this embodiment, the lateral cross-section is sequentially increased in a curved state. An embodiment in which a plurality of refrigerant housing heat diffusion frames are extended on the upper side and the lower side, and a gap for inserting a heat source is formed at a connecting portion between them. FIG. 3 is a cross-sectional view of a heat exchanger for cooling according to the longitudinal direction of the fins, and a two-dimensional mesh is stretched along the vertical direction and the horizontal direction of the refrigerant diffusion heat diffusion frame, and the refrigerant diffusion heat diffusion An embodiment in which the vertical direction of the frame is designed to be large is shown, (a) shows a state where no heating element is arranged, and (b) shows that a planar heating element is attached to a two-dimensional mesh surface. Indicates the state. It is each sectional drawing of the direction orthogonal to the longitudinal direction of a heat pipe or the thermal diffusion frame for refrigerant | coolant accommodation, Comprising: (a) is extending along the longitudinal direction the shape by the two-dimensional mesh stretched in the cross section in a cavity. (B) shows an embodiment in which the shape of a bar-shaped convex portion protruding in the cross section in the cavity is extended along the longitudinal direction, and (c) The embodiment by which the shape by the convex part of the surface shape projected in the cross section was extended along the longitudinal direction is shown, (d) is by the convex part projected to the center position of the said cross section in the cross section in a cavity The embodiment which extended the shape along the longitudinal direction is shown. An embodiment is shown in which one refrigerant raising heat pipe is extended upward and one refrigerant lowering heat pipe is extended upward. 1 shows an embodiment in which one refrigerant raising heat pipe is extended upward and two refrigerant lowering heat pipes are extended upward. 1 shows an embodiment in which one refrigerant lowering heat pipe is extended upward and two refrigerant rising heat pipes are extended upward. The manufacturing process of the heat exchanger for cooling which concerns on the said basic structure is shown, All of (1), (2), (3) have shown the top view, (4), (5) is each The perspective view by having combined the top view is shown. The manufacturing process of the heat exchanger for cooling which concerns on the said basic structure is shown, All of (1), (2), (3) have shown the top view, (4), (5) is each The perspective view by having combined the top view is shown.

  In the basic configuration, as shown in FIGS. 1 (a), (b), and (c), the top cavities of the plurality of heat pipes 2 extending in the upward direction are connected, and the inner cavity is formed. In a state where they are in communication with each other, one heat pipe 2 is installed in the horizontal direction along the horizontal direction, and each top portion protrudes from the inner wall on the lower side of the one heat pipe 2. As a result, the inner wall forms a flat state with no irregularities.

  For this reason, as described in the section of the effect, when the one heat pipe 2 is installed in the horizontal direction, the condensed liquid refrigerant does not protrude in the heat pipe 2. It can descend | lower along the inner wall of the said several heat pipe 2 via a top part.

The connection configuration in which the top portions do not protrude from the lower inner wall can be realized by die molding or welding based on a predetermined dimensional design.
A configuration in which the one heat pipe 2 is installed in an inclined state rather than in a horizontal direction will be described later with reference to FIG.

FIG. 1A shows an embodiment in which each of the tops of the plurality of heat pipes 2 and the one heat pipe 2 are in an intersecting state. In the case of such an embodiment, FIG. The refrigerant that has moved up the plurality of heat pipes 2 collides with the upper wall portion of one heat pipe 2 installed in the horizontal direction, so that the refrigerant flows in the horizontal direction and is in an adjacent position. Even though the heat pipe 2 is mixed with the raised refrigerant, the amount of the mixing is never large.
In FIG. 1A, FIG. 1B, and FIG.

  1 (a), 1 (b), and 1 (c) show an embodiment in which heat pipes 2 extending upward are provided at both ends and intermediate positions thereof, but for heat pipes 2 extending upward, 2 It is also possible to adopt a configuration in which the heat pipe 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. Is adopted.

  When the one heat pipe 2 is installed in the horizontal direction as in the embodiment shown in FIGS. 1A, 1B, and 1C, the refrigerant is condensed in the heat pipe 2. At the liquefied stage, the original heat pipe 2 must be lowered.

  That is, even if one heat pipe 2 is installed in the horizontal direction, mixing of refrigerants that rise and fall the plurality of heat pipes 2 and further alternating current tend to be extremely insufficient.

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

  1 (b) shows that the lower side surface of the wall near the top is increased by the same ratio as the cross section of the plurality of heat pipes 2 becomes higher at the top near the top. FIG. 1 (c) shows an embodiment characterized by forming a slanted shape by straight lines, and FIG. 1 (c) shows a lateral cross section in order as the cross section of the plurality of heat pipes 2 becomes the upper side near the top. An embodiment will be described in which the lower surface of the wall near the top forms a curved shape by increasing the degree of expansion.

  In these embodiments, the refrigerant that has risen up the plurality of heat pipes 2 smoothly flows in the lateral direction and flows into the heat pipes 2 that are installed in the lateral direction. This is because the refrigerant that has risen from the heat pipe 2 in the above mixes with each other.

  In particular, as shown in FIG. 1C, the refrigerant rises smoothly in the case of an arch shape in which the rate of increase in the transverse cross-section increases as it becomes the upper side near the top of the heat pipe 2. It becomes possible to change from a direction to a lateral flow.

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

  FIG. 1B shows an embodiment in which a flat surface exists as the lower 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 are curved as shown in FIG. It can be.
Further, as shown in FIG. 1 (a), at each intermediate position other than the tops of the plurality of heat pipes 2, one or a plurality of heat pipes 2 are extended in the lateral direction and An embodiment characterized in that it is connected to a plurality of heat pipes 2 can also be adopted (Note that FIG. 1A shows an embodiment in which one heat pipe 2 is extended in the lateral direction. .)
In addition, also in the heat pipe 2 extended in the horizontal direction, the lower side surface of the wall portion in the vicinity of the connection portion with the plurality of heat pipes 2 is a straight line as shown in FIG. By adopting a configuration that forms an oblique shape and a configuration that forms a curved shape as shown in FIG. 1C, smooth mixing of refrigerants can be realized.

As for the arrangement of the heat cooling fins 3 connected to the plurality of heat pipes 2 extending upward, as shown in FIG. 1 (a), the arrangement in the horizontal direction is shown in FIG. 1 (b). As shown in FIG. 1 (c), the heat-dissipating fins connecting the heat pipes of the plurality of heat pipes 2 as shown in FIG. 1 (c). 3, another heat-dissipating fin 3 that further connects the heat-dissipating fins 3 is provided in the vertical direction, and one heat pipe 2 installed on the upper side and the refrigerant storage Any arrangement state in which the thermal diffusion frame 1 is connected can be adopted.
In the case of the embodiment adopting the above-described arrangement state shown in FIG. 1B and FIG. 1C, compared with the embodiment adopting the arrangement state shown in FIG. By setting the surface area of the fin 3 large, the cooling effect can be further promoted.

  One of the heat-dissipating fins 3 is installed on both outer sides and / or in the lateral direction of the two heat pipes 2 extending in the vertical direction from both ends of the heat storage frame 1 for storing refrigerant or in the vicinity thereof. In the case of the embodiment characterized in that a plurality of heat-dissipating fins 3 are connected to the upper side of the heat pipe 2 (not shown), the heat-cooling connected to both outer sides The cooling effect of the two heat pipes 2 and the one heat pipe 2 can be promoted by the heat fins 3 and the heat cooling fins 3 connected to the upper side, respectively.

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

As shown in FIG. 3 (a), with respect to the heat storage frame 1 for storing the refrigerant, by setting the width in the vertical direction large, and stretching the two-dimensional mesh 21 along the vertical direction and the horizontal direction, An embodiment in which the heat capacity absorbed from the heat source is set large can also be adopted.
In the case of the above-described embodiment, as shown in FIG. 3B, efficient and quick heat conduction can be realized by attaching the planar heating element 4 to the surface of the two-dimensional mesh 21. it can.

  The wall portions of the refrigerant housing heat diffusion frame 1 and the heat pipe 2 contribute to cooling similarly to the heat cooling fins 3, and the amount of heat radiated per unit area is determined by the heat cooling fins 3. Is roughly the same.

In the present invention, after paying attention to the heat dissipation effect of the surface of such a heat pipe 2,
In the plurality of heat pipes 2 and / or the one heat pipe 2 and / or the heat storage frame 1 for storing refrigerant and / or in the cavity of 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 perpendicular to the longitudinal direction of the cavity is extended along the longitudinal direction, or
Cavity from the plurality of heat pipes 2 and / or the one heat pipe 2 and / or the heat diffusion frame 1 for storing refrigerant and / or the inner wall of the one or more heat pipes 2 extending in the lateral direction. Embodiment which has extended the convex part 22 which is the shape protruded in each cross section orthogonal to the longitudinal direction of this along the longitudinal direction is employable.

  By such a stretched configuration by the shape of the two-dimensional mesh 21 and a projecting configuration by the shape of the convex portion 22, the inner 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 portion of each heat pipe 2.

  FIG. 4A shows an embodiment in which the shape of the two-dimensional mesh 21 in each cross section perpendicular to the longitudinal direction of the cavity in the heat diffusing frame 1 for storing refrigerant or the heat pipe 2 is extended along the longitudinal direction. 4 (b), 4 (c), and 4 (d) all 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 housing heat diffusion frame 1 or the heat pipe 2. The embodiment extended along the direction is shown, FIG.2 (b) has shown the state of the convex part 22 with a cross section in a cross section, and FIG.2 (c) has the convex part 22 with a planar cross section. FIG. 2D shows a shape in a state in which the convex portion 22 is extended to the center position of the cavity.

  FIG. 5 shows that one refrigerant elevating heat pipe 2 is extended in a connected state from one end of the refrigerant storage heat diffusion frame 1 or in the vicinity thereof, or from an intermediate position between both ends in an upward direction. One refrigerant lowering heat pipe 2 is extended in an upward direction from the other end of the thermal diffusion frame 1 or the vicinity thereof, and the lower side surface of the horizontal heat pipe 2 is the refrigerant rising heat pipe 2. An embodiment is characterized in that it is installed in an inclined state so as to be sequentially lowered from the upper end toward the upper end of the refrigerant descending heat pipe 2.

  For example, in each of the embodiments shown in FIGS. 1, 2, and 3, the horizontal heat pipe 2 on the upper side is installed in the horizontal direction, and as a result, the heat pipe 2 extended in the upper direction is a refrigerant. However, there is a case where a so-called gas-liquid mixture state occurs, which causes a slight hindrance to the smooth rise of the refrigerant vapor.

  On the other hand, in the case of the above-described embodiment, the refrigerant vapor rises in the refrigerant raising heat pipe 2 on one side, and the refrigerant liquid falls in the other refrigerant lowering heat pipe 2. The refrigerant sequentially circulates through the thermal diffusion frame 1.

As a result, an efficient rise of the refrigerant vapor can be realized, and as a result, efficient cooling can also be realized.
In FIG. 5, the refrigerant raising heat pipe 2 is extended upward from the intermediate positions at both ends of the refrigerant housing heat diffusion frame 1. By extending to such an intermediate position, heat dissipation is achieved. The space for extending the cooling fin in the lateral direction is from the intermediate position to the one side end portion, and it is not necessary to extend further from the one side end portion to the lateral side, thereby realizing a compact design. .

  FIG. 6 shows two refrigerant lowering heat pipes 2 extending in an upward direction from or near both ends of the refrigerant storage heat diffusion frame 1, and the both ends of the refrigerant storage heat diffusion frame 1. One refrigerant raising heat pipe 2 is extended in an upward direction from the middle position of the refrigerant, and the lower side surface of the horizontal heat pipe 2 extends from the upper end of the refrigerant raising heat pipe 2 to the refrigerant lowering heat pipe. 2 shows an embodiment characterized in that it is installed in an inclined state so as to be sequentially lowered toward the upper end of 2.

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

  FIG. 7 shows that two refrigerant rising heat pipes 2 are connected in an upward direction from both ends of the refrigerant storage heat diffusion frame 1 or the vicinity thereof, and the both ends of the refrigerant storage heat diffusion frame 1. One refrigerant lowering heat pipe 2 is extended in an upward direction from the middle position of the refrigerant, 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 characterized in that it is installed in an inclined state so as to be sequentially lowered toward the upper end of 2.

  In the embodiment shown in FIG. 7, the embodiment shown in FIG. 6 and the refrigerant raising heat pipe 2 and the refrigerant lowering heat pipe 2 are reversed, but as in the case of the embodiment shown in FIG. The circulation of the refrigerant can be realized.

  As in the case of the embodiment shown in FIG. 3A, the refrigerant diffusion heat diffusion frame 1 shown in FIG. 6 employs a two-dimensional mesh 21 having a predetermined gap, as shown in FIG. 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 refrigerant-storing heat diffusion frame 1 shown in FIG. 7 employs two extending configurations on the upper and lower sides along the lateral direction on both sides, and in the case of the embodiment of FIG. Similarly, a plurality of heating elements 4 can be inserted between the upper and lower connecting portions.
In addition, in the case where the heating element 4 is attached as shown in FIGS. 3B and 6 and the case where it is inserted as shown in FIGS. 2 and 7, only one heating element 4 is provided. Instead, a plurality can be targeted.

  In the case where the heating element 4 and the refrigerant lowering heat pipe 2 are close to each other or adjacent to each other, the lowering of the refrigerant lowering heat pipe 2 hinders the lowering of the refrigerant and exhibits a sufficient circulation effect. I can't.

  In consideration of such points, 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 lowering heat pipe 2.

  In particular, as shown in FIGS. 5, 6, and 7, the heat insulating region 5 is disposed between the lower region of the refrigerant descending heat pipe 2 and the region where the heating element 4 exists. Is used, the heat generated from the heating element 4 by the heat insulating region 5 can be prevented from being directly transferred to the lower region of the refrigerant lowering heat pipe 2.

In addition, as shown in FIGS. 5, 6, and 7, when the heat insulating region 5 is coupled to the refrigerant lowering heat pipe 2 along the vertical direction, the transfer of heat generated from the heating element 4 can be sufficiently prevented. It becomes possible and contributes to the circulation of a smooth refrigerant.
As shown in FIGS. 5 and 6, the heat insulating region 5 simply adopts a structure of a space surrounded by a wall part 51 or a structure in which a heat insulating material 52 is housed inside the wall part 51 and inside thereof. can do.

  Hereinafter, it demonstrates according to an Example.
