[0053] Hereinafter, embodiments of the present invention will be described with reference to the attached drawings.

[0054] A pulsating heat pipe module according to an embodiment of the present invention is a heat transfer mechanism that transfers heat through the flow of a working fluid while evaporation and condensation are continuously performed as the working fluid circulates through a closed-loop path, and is used as a heat dissipation device that receives heat from a high heat source and releases heat to a low heat sink to cool the high heat source.

[0055] FIG. 1 is a perspective view showing a T-shaped vibrating heat pipe module according to a first embodiment of the present invention. FIG. 2 is a side view of the vibrating heat pipe module shown in FIG. 1. FIG. 3 is an exploded perspective view of the vibrating heat pipe module shown in FIG. 1.

[0056] Referring to FIGS. 1 to 3, the vibrating heat pipe module according to the first embodiment of the present invention is described as having a “⊥” shape with an inverted T-shape cross-section.

[0057] The above-mentioned vibrating heat pipe module includes a channel plate (10), a bottom plate (20), and a cover plate (30).

[0058] The above channel plate (10), the above bottom plate (20), and the above cover plate (30) are all formed using a press, and the forming method will be described in detail later. However, this is not limited thereto, and it is also possible to manufacture at least some or all of the above channel plate (10), the above bottom plate (20), and the above cover plate (30) using various methods such as etching in addition to the press method.

[0059] The above channel plate (10) is formed to be elongated in the vertical direction, and being formed to be elongated in the vertical direction may include being formed to be elongated in the up-down direction or in a direction inclined at a predetermined angle from the up-down direction. In this embodiment, the channel plate (10) is described as an example of a vertical plate arranged to be elongated in the up-down direction.

[0060] The above-mentioned bottom plate (20) is formed to be elongated in the horizontal direction, and being formed to be elongated in the horizontal direction may include being formed to be elongated in the horizontal direction or in a direction inclined at a predetermined angle from the horizontal direction. In this embodiment, the bottom plate (20) is described as an example of a horizontal plate that is elongated in the horizontal direction perpendicular to the channel plate (10).

[0061] However, this is not limited to this, and the angle formed by the channel plate (10) and the bottom plate (20) can be varied and applied.

[0062] Referring to FIG. 2, the channel plate (10) and the bottom plate (20) are perpendicular to each other, and a secondary battery can be mounted in the space between the channel plate (10) and the bottom plate (20). Since the channel plate (10) and the bottom plate (20) are perpendicular to each other, the secondary battery can be in close contact, thereby maximizing the heat transfer area and improving the heat dissipation effect of the secondary battery. Here, the secondary battery may include a cell, a cell module, and a cell pack.

[0063] The above channel plate (10) is a plate formed to form an operating fluid channel by piercing a first base plate into a first fluid pattern that is preset by a press mold. The first base plate is a flat plate made of AL 10 or AL 30 material, and is described as having a thickness of about 0.5 mm to 1.0 mm.

[0064] In the above channel plate (10), a plurality of flow holes (11) and a plurality of flow guides (12) forming the boundaries of the flow holes are formed by the piercing process.

[0065] The above working fluid channel is the entire flow path through which the working fluid flows when the above vibrating heat pipe module is operated, and is a flow path formed by the flow path holes (11) of the channel plate (10) and the flow path groove (21) of the bottom plate (20).

[0066] FIG. 4 is a drawing showing a state in which a channel plate and a bottom plate are combined according to a first embodiment of the present invention, FIG. 5 is an enlarged view of part A of FIG. 4, and FIG. 6 is a plan view of a channel plate according to a first embodiment of the present invention.

[0067] Referring to FIGS. 4 to 6, in this embodiment, the first flow path pattern of the channel plate (10) is described as an example of an unloop pattern with an open bottom so as to communicate with the flow path groove (21) of the bottom plate (20). However, it is not limited thereto, and the width, length, and shape of the first flow path pattern can be varied and applied according to the characteristics of the working fluid.

[0068] The above-mentioned fluid passage holes (11) are formed in multiple numbers by dividing the working fluid channel, thereby defining the first fluid passages through which the working fluid flows. The above-mentioned fluid passage holes (11) are through holes formed by piercing.

[0069] Referring to FIG. 6, the Euro holes (11) are described as including a plurality of circumferential holes (11a) formed to form a multiple bent Euro along the circumference of the channel plate (10), and a plurality of straight holes (11b) formed inside the circumferential holes (11a) and extending in the vertical direction.

[0070] The above circumferential hole (11a) is connected by Euro bridges (13) described later. The above circumferential hole (11a) may be provided with an inlet (not shown) for injecting working fluid.

[0071] The above linear holes (11b) are formed in multiple numbers in the vertical direction (Y) and spaced apart from each other at a set interval to guide the working fluid in the vertical direction (Y). However, this is not limited thereto, and the width, length, shape, and number of the flow path holes (11) are pre-set according to the working fluid channel, and can be varied and applied as long as they can be formed by the piercing process.

[0072] The above-mentioned Euro bridge (13) is formed by piercing the Euro holes (11) in the first disc and then stepping a portion of the remaining part so that its thickness is thinner than the thickness of the channel plate (10). The above-mentioned Euro bridge (13) connects adjacent Euro holes (11) and serves as a fluid passage through which the working fluid can pass between the Euro holes (11). That is, when piercing the first disc, if the circumferential hole (11a) is processed as a single hole, the outer and inner sides of the circumferential hole (11a) are separated. Therefore, the circumferential hole (11a) is divided into multiple parts and pierced, and the portion connecting the circumferential holes (11a) is step-forged to form the above-mentioned Euro bridge (13). In this embodiment, the Euro bridge (13) is described as connecting only the circumferential holes (11a), but it is not limited thereto and it is also possible to connect the straight holes (11b). The thickness of the Euro bridges (13) is processed to be about 40% to 80% of the thickness of the channel plate (10).

[0073] The above-mentioned flow guide (12) is the remaining portion after piercing the flow holes (11) in the first disc, forms the boundary of the flow holes (11), and a plurality of them are formed spaced apart from each other at a predetermined interval. In this embodiment, the flow guide (12) is formed in the shape of a long rod in the vertical direction (Y) and is described as having the shape of a comb. The flow guide (12) serves to guide the flow of the working fluid by being formed long in the vertical direction (Y), which is the flow direction of the working fluid in the channel plate (10). The shape or size of the flow guide (12) is pre-set according to the first flow pattern and can be applied by changing it in various ways.

[0074] Referring to FIGS. 5 and 6, the Euro guides (12) are formed to protrude downward by a set length (d) from the left and right side portions (10a) and (10b) of the channel plate (10). The set length (d) is described as being formed to be equal to the depth of the slot (22) of the bottom plate (20) described later. Accordingly, the lower portion of the Euro guides (12) is inserted so as to be in contact with the bottom surface of the slot (22).

[0075] In this embodiment, the lower portion of the fluid guides (12) is inserted until it comes into contact with the bottom surface of the slot (22). However, this is not limited thereto, and it is also possible for the lower portion of the fluid guides (12) to be inserted into the slot (22) but only to a position spaced apart from the bottom surface of the slot (22) by a predetermined height, and it is also possible to have them placed above the slot (22) without being inserted into the slot (22) so that the working fluid can flow through the slot (22).

[0076] FIG. 7 is a perspective view of a bottom plate according to the first embodiment of the present invention.

[0077] Referring to FIGS. 3 and FIGS. 7, the bottom plate (20) is a plate forming the bottom of the vibrating heat pipe module, and the lower part of the channel plate (10) is inserted and joined.

[0078] The above-mentioned bottom plate (20) is a plate formed by forming the second plate. The above-mentioned second plate is a flat plate made of AL 10 or AL 30 material, and is described as having a thickness of about 0.5 mm to 1.0 mm.

[0079] The upper surface of the above-mentioned bottom plate (20) is formed into a preset second Euro pattern, thereby forming the plurality of Euro grooves (21) and the plurality of slots (22).

[0080] The above-mentioned fluid grooves (21) are grooves formed by the press. The above-mentioned fluid grooves (21) are formed to communicate with the fluid holes (11) so that the working fluid moving downward along the fluid holes (11) of the channel plate (10) flows. The above-mentioned fluid grooves (21) define the second fluid paths through which the working fluid flows.

[0081] The above slots (22) are also grooves formed by the above press. The above slots (22) are formed so that the lower end of the above flow guides (12) is inserted. The above slots (22) are described as being formed long in the left-right direction from the center of the upper surface of the bottom plate (20) so that the channel plate (10) is inserted into the center of the upper surface of the bottom plate (20).

[0082] The above Euro grooves (21) and slots (22) can be formed in one step with a single forming process.

[0083] Figure 8 is a cross-sectional view along line BB in Figure 7, and Figure 9 is a drawing showing the state in which a cooling plate is combined with the bottom plate shown in Figure 8.

[0084] Referring to FIGS. 8 and 9, a plurality of embossings (23) are formed on the lower surface of the bottom plate (20) by forming the Euro grooves (21) and the slots (22) downwardly.

[0085] By forming the embossings (23) on the lower surface of the bottom plate (20), the heat transfer area with the cooling plate (50) mounted on the lower surface of the bottom plate (20) is increased, thereby further improving heat dissipation efficiency. The cooling plate (50) is a cooling unit for providing a cooling source to cool a working fluid. In FIGS. 8 and 9, reference numeral 40 is a thermal interface material, such as a gap pad, for filling the gap between the bottom plate (20) and the cooling plate (50).

[0086] Referring to FIG. 3, the cover plate (30) is formed to cover the channel plate (10) and the bottom plate (20) respectively, and is a plate that shields the flow holes (11) and the flow grooves (21).

[0087] The above cover plate (30) is a plate formed by forming the third plate using a press. The above third plate is a flat plate made of AL 10 or AL 30 material, and is described as having a thickness of about 0.1 mm to 0.3 mm.

[0088] The above cover plate (30) includes a first cover plate (31) and a second cover plate (32). In this embodiment, since the cross-section of the vibrating heat pipe module is in the shape of an inverted T, the first cover plate (31) and the second cover plate (32) are formed with the same shape.

[0089] The first cover plate (31) comprises a first vertical portion (31a) formed to be joined to the front surface of the channel plate (10) and to shield the open front surface of the flow hole (11), and a first horizontal portion (31b) formed to be bent forward from the bottom of the first vertical portion (31a) and extended, and to be laminated on the upper surface of the bottom plate (20) and to shield the open upper surface of the flow grooves (21).

[0090] The second cover plate (32) comprises a second vertical portion (32a) formed to be joined to the rear surface of the channel plate (10) and to cover the open rear surface of the flow hole (11), and a second horizontal portion (32b) formed to be bent backward from the bottom of the second vertical portion (32a) and extended, and to be laminated on the upper surface of the bottom plate (20) and to cover the open upper surface of the flow grooves (21).

[0091] The first and second cover plates (31)(32) may include a clad layer in which an adhesive material such as flux is laminated on at least one of the front and rear surfaces of a metal plate made of a metal such as aluminum. Additionally, the first and second cover plates (31)(32) may be formed as thin plates with a thickness thinner than that of the channel plate (10) and the bottom plate (20). In this embodiment, the first and second cover plates (31)(32) are described as having a thickness of approximately 0.1 mm to 0.3 mm.

[0092] Meanwhile, in this embodiment, the first and second cover plates (31)(32) are clad material and the channel plate (10) and the bottom plate (20) are aluminum (AL) material, but are not limited thereto. It is also possible for the first and second cover plates (31)(32) to be aluminum (AL) material and for the channel plate (10) and the bottom plate (20) to be clad material including a clad layer.

[0093] The method for manufacturing a vibrating heat pipe module according to the first embodiment of the present invention configured as described above is as follows.

[0094] A method for manufacturing a vibrating heat pipe module according to a first embodiment of the present invention utilizes a press and includes a piercing press processing step, a forging press processing step, a first forming press processing step, a second forming press processing step, and a joining step.

[0095] First, in the above piercing press processing step, the above channel plate (10) is formed by piercing the above flow holes (11) in a first base plate of a preset thickness.

[0096] In the above piercing press processing step, the first plate is pierced into the first flow path pattern using a press to form the flow path holes (11). The first flow path pattern is a flow path pattern in which the working fluid channel is divided into the plurality of flow path holes (11), and at least a portion of the plurality of flow path holes (11) can be connected by the flow path bridge (13). That is, if the working fluid channel is pierced into a single flow path hole, there is a problem in that the remaining part after piercing the flow path holes in the first plate separates and detaches into pieces. On the other hand, in this embodiment, since the working fluid channel is pierced into the plurality of flow path holes, the remaining part after piercing the flow path holes (11) in the first plate is not separated, and the channel plate (10) can be formed as a single plate.

[0097] In the above piercing press processing step, it is also possible to process the first disc into the contour shape of the vibrating heat pipe module.

[0098] The above forging press processing step is a step of forming the flow bridge (13) by forging the part to be connected to the flow holes (11) in the remaining part after processing the flow holes (11) in the channel plate (10).

[0099] In the above forging press processing step, the flow channels (11) are processed in the channel plate (10), and the remaining portion where the flow channels (11) need to be connected is forged in a stepped manner so that it is thinner than the thickness of the channel plate (10) to form the flow channel bridge (13). The flow channel bridge (13) serves to connect the flow channels (11) so that the working fluid of adjacent flow channels (11) can move to each other. The flow channel bridge (13) can be forged using a pre-made forging press die (not shown). The thickness of the flow channel bridge (13) can be processed to be about 40% to 80% of the thickness of the channel plate (10).

[0100] The first forming press processing step is a step of forming the bottom plate (20) having the lower flow grooves (21) and lower slots (22) formed by forming a second base plate of a preset thickness into a preset second flow pattern using a forming press mold.

[0101] In the first forming press processing step, the flow grooves (21) and the slots (22) are formed concavely downward, and the depth of the flow grooves (21) and the slots (22) can be formed to be as deep as the protruding length (d) of the flow guides. As the flow grooves (21) and the slots (22) are formed, embossings (23) protruding downward by the depth of the flow grooves (21) and the slots (22) can be formed on the lower surface of the bottom plate (10).

[0102] In the first forming press processing step described above, the Euro grooves (21) and slots (22) are formed at once, but this is not limited thereto, and it is also possible to form them at different depths or form them separately.

[0103] The second forming press processing step is a step of forming the cover plate (30) by bending a third base plate of a preset thickness using a forming press mold.

[0104] In the second forming press processing step, the third plate is formed by bending a portion of it through forming, so as to form it into a shape that can cover the front and rear surfaces of the channel plate (10) and the upper surface of the bottom plate (20). The first and second cover plates (31)(32) can be manufactured identically.

[0105] The first and second cover plates (31)(32) may have a clad layer formed by laminating an adhesive material, such as flux, on at least one of the front and rear surfaces of a metal plate made of a metal such as aluminum, in order to simplify joining processes such as brazing. Additionally, the first and second cover plates (31)(32) may be formed as thin plates with a thickness thinner than that of the channel plate (10) and the bottom plate (20). In this embodiment, the first and second cover plates (31)(32) are described as having a thickness of approximately 0.1 mm to 0.3 mm.

[0106] The above joining step is a step of completing the vibrating heat pipe module by assembling the channel plate (10), the bottom plate (20), and the cover plate (30) and brazing them together.

[0107] In the above joining step, the channel guides (12) of the channel plate (10) are inserted into the slots (22) of the bottom plate (20), and then the channel plate (10) and the bottom plate (20) are brazed together. Additionally, the first and second cover plates (31) and (32) are each laminated on the outer sides of the channel plate (10) and the bottom plate (20), respectively, and then brazed together. However, this is not limited to this method, and various joining methods such as diffusion bonding and bonding, in addition to brazing, can be applied.

[0108] The vibrating heat pipe module according to the present invention, configured as described above, is manufactured by a press method, making it easier to produce than when manufactured by a conventional etching method, thereby reducing working time and costs.

[0109] In addition, because the manufacturing method is simple, it is easy to process more diverse and complex Euro patterns, thereby maximizing the heat dissipation effect.

[0110] Meanwhile, FIG. 10 is a plan view of a channel plate of a vibrating heat pipe module according to a second embodiment of the present invention.

[0111] Referring to FIG. 10, the vibrating heat pipe module according to the second embodiment of the present invention differs from the first embodiment in that the first flow path pattern of the channel plate (110) is a loop-shaped pattern in which at least some of the plurality of flow path holes (111) are in communication with each other, and the rest of the configuration and operation are similar to the first embodiment. Therefore, a detailed description of the similar configuration is omitted, and the description focuses on the differences.

[0112] The above-mentioned Euro holes (111) include a plurality of circumferential holes (111a) formed to form a multiple bent flow path along the circumference of the channel plate (110), and internal holes (111b) formed inside the circumferential holes (111a), extending vertically, and having at least a portion bent to change the flow direction of the working fluid.

[0113] Each of the internal holes (111b) is formed with a bent upper end and an open lower end, forming an inverted U-shape so that the working fluid moves upward and then moves downward. However, this is not limited thereto, and the width, shape, etc. of the internal holes (111b) can be varied and applied.

[0114] In this embodiment, a plurality of Euro bridges (113) are arranged in a horizontal line as an example. However, this is not limited thereto, and the number or position of the Euro bridges (113) can be varied and applied.

[0115] Meanwhile, FIG. 11 is a perspective view showing an L-shaped vibrating heat pipe module according to a third embodiment of the present invention. FIG. 12 is an exploded perspective view of the vibrating heat pipe module shown in FIG. 11. FIG. 13 is a perspective view of a bottom plate according to a third embodiment of the present invention.

[0116] Referring to FIGS. 11 to 13, the vibrating heat pipe module according to the third embodiment of the present invention comprises a channel plate (310), a bottom plate (320), and a cover plate (330). The channel plate (310) is inserted at a position spaced apart from the center on the upper surface of the bottom plate (320), and the cross-section of the vibrating heat pipe module is formed in an L-shape, which is different from the first embodiment. Since the remaining configuration and operation are similar to the first embodiment, a detailed description of the similar configuration is omitted, and the description focuses on the differences.

[0117] On the upper surface of the above-mentioned bottom plate (320), a plurality of flow grooves (321) and slots (320) are formed by a forming process using a press.

[0118] The slot (320) is a groove formed at a position spaced rearward from the center on the upper surface of the bottom plate (320) so that the lower end of the flow guides (312) of the channel plate (310) is inserted therein.

[0119] The above cover plate (330) includes a first cover plate (331) and a second cover plate (332) and is formed by the press. In this embodiment, since the cross-section of the vibrating heat pipe module is L-shaped, the first cover plate (331) and the second cover plate (332) are formed in different shapes.

[0120] The first cover plate (331) comprises a first vertical portion (331a) formed to be joined to the front surface of the channel plate (310) and to shield the open front surface of the flow holes (311), and a first horizontal portion (331b) formed to be bent forward from the bottom of the first vertical portion (331a) and laminated on the upper surface of the bottom plate (320) to shield the upper surface of the flow grooves (321). That is, the cross-section of the first cover plate (331) is formed in an L-shape.

[0121] The second cover plate (332) is formed in a flat shape to be joined to the rear surface of the channel plate (310) and to cover the open rear surface of the Euro holes (311).

[0122] FIG. 14 is a cross-sectional view along line CC in FIG. 13. FIG. 15 is a drawing showing the state in which a cooling plate is combined with the bottom plate shown in FIG. 14.

[0123] Referring to FIGS. 14 and 15, the embossings (323) are formed on the lower surface of the bottom plate (320), so that the heat transfer area with the cooling plate (350) mounted on the lower surface of the bottom plate (320) is increased, thereby further improving heat dissipation efficiency. In FIGS. 14 and 15, reference numeral 340 is a thermal interface material, such as a gap pad, for filling the gap between the bottom plate (320) and the cooling plate (350).

[0124] Meanwhile, FIG. 16 is a schematic side view of a vibrating heat pipe module according to a fourth embodiment of the present invention. FIG. 17 is an exploded perspective view of the vibrating heat pipe module shown in FIG. 16.

[0125] The vibrating heat pipe module according to the fourth embodiment of the present invention comprises a channel plate (410), a bottom plate (420), and a cover plate (430). It differs from the first embodiment in that a plurality of channel plates (410) are inserted into and joined to the bottom plate (420), and the remaining configuration and operation are similar to the first embodiment. Therefore, a detailed description of the similar configuration is omitted, and the description focuses on the differences.

[0126] The plurality of channel plates (410) are inserted at positions spaced apart from each other at a predetermined distance on the upper surface of the bottom plate (420). At least some of the channel plates (410) have different flow path patterns formed so that the direction of the working fluid is different from each other.

[0127] In this embodiment, the channel plates (410) are described as including two first and second channel plates (411) (412). However, this is not limited thereto, and the number of channel plates (410) can be varied to two or more.

[0128] The first flow pattern of the first channel plate (411) may have first flow holes formed long in the vertical direction, and the second flow pattern of the second channel plate (412) may have second flow holes formed long in the horizontal direction. That is, in this embodiment, the first flow pattern of the first channel plate (411) and the flow pattern of the second channel plate (412) are described as being formed in directions perpendicular to each other. However, this is not limited to this, and various directions other than perpendicular can be applied. By forming the flow patterns of the first channel plate (411) and the second channel plate (412) differently from each other, there is an advantage that heat transfer is possible in more directions.

[0129] On the upper surface of the floor plate (420), first and second slots (not shown) are formed at a predetermined distance from each other so that the lower portions of the first and second channel plates (411) (412) are respectively inserted.

[0130] The above cover plate (430) includes a first cover plate (431), a second cover plate (432), and an intermediate plate (433).

[0131] The first cover plate (431) comprises a first vertical portion (431a) formed to be joined to the front surface of the first channel plate (411) to shield the open front surface of the first flow holes (not shown), and a first horizontal portion (431b) formed to be bent forward from the lower end of the first vertical portion (431a) and extended, and laminated on the upper surface of the bottom plate (420) to shield the open upper surface of the flow grooves (not shown) of the bottom plate (420).

[0132] The second cover plate (432) comprises a second vertical portion (432a) formed to be joined to the rear surface of the second channel plate (412) and to shield the open rear surface of the second Euro holes (not shown), and a second horizontal portion (432b) formed to be bent backward from the second vertical portion (432a), extended, and laminated on the upper surface of the bottom plate (420) to shield the open upper surface of the Euro grooves (not shown).

[0133] The intermediate plate (433) is a flat plate placed between the first channel plate (411) and the second channel plate (412). In this embodiment, since there are two channel plates (410), the intermediate plate (433) is described as one, but it is not limited to this and the number of intermediate plates (433) can be changed differently depending on the number of channel plates (410).

[0134] In this embodiment, the vibrating heat pipe module is described as having an inverted T-shape according to the first embodiment, but it is not limited thereto and can also be applied to an L-shape according to the third embodiment.

[0135] The vibrating heat pipe module according to the fourth embodiment of the present invention configured as described above has the advantage of being able to respond to high heat sources because the amount of working fluid injected can be further increased by including the plurality of channel plates (410).

[0136] In addition, since the direction of each flow pattern of the plurality of channel plates (410) can be designed differently, heat transfer is possible in multiple directions, and thus the heat dissipation efficiency can be further improved.

[0137] In the embodiments of the present invention, the channel plate is formed by piercing and the bottom plate is formed by forming, and the vibrating heat pipe module is manufactured by a press method as an example; however, the invention is not limited thereto, and if the vibrating heat pipe module according to the embodiments of the present invention can be manufactured, it is of course possible to manufacture at least part or all of the vibrating heat pipe module by a method other than the press method.

[0138] The present invention has been described with reference to the embodiments illustrated in the drawings, but this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true technical scope of protection of the present invention should be determined by the technical spirit of the appended claims.

[0139] According to the present invention, a vibrating heat pipe module with improved heat dissipation effect can be manufactured.
