Description

Technical Field

[0001] The utility model relates to a cooling module and a battery disconnecting device including the cooling module. More specifically, it relates to a cooling module using a cooling fluid and a battery disconnecting device including the cooling module. Background Art

[0002] Moving away from traditional vehicles powered by fossil fuels such as gasoline or diesel, research on electric vehicles (EVs), hybrid electric vehicles (HEVs), hydrogen vehicles (HVs), etc., which use electricity or hydrogen to drive the vehicle, is actively underway.

[0003] As described above, EVs, HEVs, HVs, etc. must be equipped with a battery for supplying the electricity to drive the vehicle. When the vehicle and the battery driving the vehicle are continuously operating, high heat is generated in the battery and in devices for opening and closing the battery and the load, such as a battery disconnect unit (BDU) densely equipped with switches, etc.

[0004] At this time, if the generated high heat is ignored, the battery, the BDU, or various components provided in the vehicle may be damaged. Therefore, compared with traditional-structured vehicles, that is, vehicles driven by fossil fuels, the demand for effective heat dissipation of the battery in EVs, HEVs, HVs, etc. has increased.

[0005] Methods widely used for cooling the battery can be classified into an air cooling method and a water cooling method. In the case of existing vehicles using fossil fuels, since the heat generated by the battery is not excessive, sufficient cooling efficiency can be expected even by adopting the air cooling method. On the contrary, EVs, HEVs, HVs, etc. including batteries that release high heat generally adopt the water cooling method because it is difficult to sufficiently cool only by the air cooling method.

[0006] However, when cooling the battery by the water cooling method, the path through which the heat transfer medium, i.e., water that receives the heat of the battery, flows must be completely physically isolated from the battery. That is, water flows inside the path, but the connection with the outside must be disconnected.

[0007] Therefore, in order to cool the battery by the water cooling method, additional components such as rubber rings for preventing any leakage of water are required. But this leads to an increase in the unit price of the product and a decrease in assemblability, etc. In addition, the following problem may occur. Since non-airtight empty spaces are generated between each structure, the heat transfer rate decreases, resulting in a decrease in cooling efficiency.

[0008] Therefore, there is an urgent need to develop a cooling module and a battery disconnect device including the cooling module, and the cooling module has high cooling efficiency by improving the heat transfer rate between the heat generating structure and the heat absorbing structure.

[0010] The present utility model is proposed in consideration of the above factors. The object of the present utility model is to provide a cooling module and a battery disconnect device including the cooling module, and the cooling module has high cooling efficiency.

[0011] Another object of the present utility model is to provide a cooling module and a battery disconnect device including the cooling module, and the cooling module has a structure capable of stably ensuring electrical insulation from the combined electronic device.

Figure 2 is an exploded perspective view of a battery disconnect device according to an embodiment of the present invention, viewed from above. Figure 3 is along Figure 1 a cross-sectional view taken along the section line I-I of Figure 4 and Figure 5 are perspective views of a cooling module according to an embodiment of the present invention, viewed from different angles from each other. Figure 6 and Figure 7 are exploded perspective views of a cooling module according to an embodiment of the present invention, viewed from different angles from each other.

[0062] Referring to Figure 1 , a battery disconnect device 1 according to an embodiment of the present invention is disclosed. The battery disconnect device 1 according to the present embodiment is a device for disconnecting the energization of the circuit when an overcurrent flows in the circuit connecting the battery and the load, thereby preventing damage to the battery and other structures due to the overcurrent.

[0063] Such a battery disconnect device 1 can be provided in any form that can allow or disconnect the energization between the battery (not shown) and the load. As an example, the battery disconnect device 1 can be provided as a BDU (Battery Disconnect Unit).

[0064] The battery disconnect device 1 according to the present embodiment can be provided in any vehicle provided with a battery (not shown), such as an EV, HEV, Plug-in Hybrid Electric Vehicle (PHEV), HV, etc. Alternatively, the battery disconnect device 1 can also be provided in any power device provided with a battery, for example, an Energy Storage System (ESS), etc.

[0065] Referring to Figures 1 to 3 , the battery disconnect device 1 according to an embodiment of the present invention may include a disconnect module 10 and a cooling module 20. In the present embodiment, the disconnect module 10 is a structure for allowing or disconnecting the energization of the above circuit.

[0066] According to an embodiment of the present invention, the disconnect module 10 may include a housing 12. The housing 12 is a structure for providing a base for accommodating or disposing another structure of the present battery disconnect device 1.

[0067] In this embodiment, the housing 12 can be provided as a box-shaped structure having a predetermined space inside. In addition, the housing 12 can be made of a material such as plastic having a predetermined rigidity. At this time, the housing 12 may include a material having a predetermined insulation property to ensure the insulation performance between the inside and the outside.

[0068] On the other hand, in this embodiment, the housing 12 has a box shape, but is not limited thereto, and the shape of the housing 12 can be appropriately deformed according to requirements. For example, the housing 12 can be set to open or bend a part according to the shape of the space where the battery disconnecting device 1 is provided or the shape of other components of the battery disconnecting device 1.

[0069] Refer to Figures 1 to 3 , the disconnecting module 10 of the battery disconnecting device 1 according to an embodiment of the present invention may include a plurality of contactors 14 and a busbar 16.

[0070] In this embodiment, the plurality of contactors 14 and the busbar 16 can be combined and energized in a predetermined manner, so that an external battery, a fuse 18 described later, and other structures provided in the vehicle can be energized. For this purpose, the contactors 14 and the busbar 16 can be made of a conductive material.

[0071] On the other hand, in this embodiment, the contactor 14 can be provided as a component having a hole capable of fastening a coupling member 30 described later, so as to be able to be coupled to other structures. However, if the contactor 14 can be configured to be electrically connected to other structures, its shape is not particularly limited.

[0072] According to this embodiment, the plurality of contactors 14 can be provided in a predetermined space in a predetermined manner. For example, the plurality of contactors 14 can be arranged in a row inside the housing 12 described above. However, the manner and position of arranging the plurality of contactors 14 can be changed differently according to requirements.

[0073] Refer to Figures 1 to 4 , the busbar 16 can be provided so as to energize the contactors 14 and an external battery or other devices. At this time, when current flows, heat may be generated in the busbar 16. Excessive heat generated from the busbar 16 may cause a fire, and may shorten the life of the components due to deterioration or reduce the power-on function or the current-disconnecting function caused by overcurrent of the battery disconnecting device 1. To prevent this, the busbar 16 can be cooled.

[0074] In this embodiment, the busbar 16 can be provided as a flat plate-shaped component provided in the housing 12. Therefore, since the busbar 16 can contact the external air or a cooling module 20 described later through a large area, it can be cooled more effectively.

[0075] In addition, in the present embodiment, the power collecting plate 16 is combined with the upper surface of the housing such that one surface can be exposed to the outside. However, if cooling can be performed by the cooling module 20 described later, the position where the power collecting plate 16 is provided in the housing 12 is not particularly limited.

[0076] On the other hand, in the present embodiment, more than one power collecting plate 16 can be provided. In the described embodiment, a total of six power collecting plates 16 are provided and arranged in a row along the Y-axis direction. The arrangement of such multiple power collecting plates 16 can be appropriately changed according to the relative positions with the contactor 14 and other devices.

[0077] At this time, the six power collecting plates 16 can be formed of flat plate-shaped members having different shapes from each other. The shape of each of these power collecting plates 16 can be appropriately changed, for example, a part is bent to match the part provided in the housing 12.

[0078] On the other hand, in the present embodiment, the power collecting plate 16 is provided as a flat plate-shaped member. The shape of the power collecting plate 16 according to the embodiment is not limited to that shown in the figure, and if it can be in direct or indirect contact with the cooling module 20, the shape of the power collecting plate 16 is not particularly limited.

[0079] Refer to Figure 2 , in the present embodiment, more than one power collecting plate side coupling member hole 17 can be provided in the power collecting plate 16. The power collecting plate side coupling member hole 17 is a structure through which a coupling member 30 described later can penetrate and be coupled. Regarding this, it will be described later together with the coupling member 30.

[0080] Refer to again Figure 2 , the disconnecting module 10 of the battery disconnecting device 1 according to an embodiment of the present utility model may include a fuse 18. In the present embodiment, the fuse 18 is a structure for preventing damage or accidents to other components due to overcurrent.

[0081] In the present embodiment, the fuse 18 can be composed of a device that operates to disconnect when an overcurrent is applied. In addition, as shown at the lower right end of Figure 2 , a part of the plurality of contactors 14 can be coupled to the fuse 18. In addition, the contactor 14 coupled to the fuse 18 can be electrically connected to the power collecting plate 16.

[0082] Therefore, the fuse 18 detects whether an overcurrent flows in the power collecting plate 16, and if an overcurrent flows, it disconnects the power supply. Since the process of the fuse 18 disconnecting the power supply is a well-known technique, its detailed description will be omitted.

[0083] Hereinafter, the cooling module 20 of the battery disconnecting device 1 according to an embodiment of the present utility model will be described. As described above, the cooling module 20 according to an embodiment of the present utility model can be configured to cool the heat generated in the bus bar 16 of the disconnecting module 10.

[0084] Referring to Figures 4 to 7 , the cooling module 20 according to an embodiment of the present utility model may include a heat transfer member 100, a cooling pipe 200, and a heat dissipation member 300. The heat transfer member 100 is a component that receives heat from the bus bar 16 through the heat dissipation member 300 and transfers it to the cooling pipe 200 described later or releases it to the outside. To this end, the heat transfer member 100 may be made of a material having a high thermal conductivity, for example, aluminum or an aluminum-containing alloy material, etc.

[0085] In this embodiment, the heat transfer member 100 may include a heat transfer main body portion 110. The heat transfer main body portion 110 may be provided as a block-shaped component extending in one direction. At this time, the direction in which the heat transfer main body portion 110 extends may be parallel to the direction in which the plurality of bus bars 16 are arranged. In the above-described embodiment, the heat transfer main body portion 110 may extend in the Y-axis direction, which is the direction in which the 6 bus bars 16 are arranged.

[0086] Therefore, at least a part of the heat transfer main body portion 110 can be as close as possible to any one of the plurality of bus bars 16, so that the heat generated in the bus bar 16 can be effectively absorbed.

[0087] According to this embodiment, the heat transfer main body portion 110 may include an upper surface 112, a lower surface 113, and side surfaces 114. The upper surface 112 may be defined as the surface facing away from the bus bar 16, so that the heat transferred to the heat transfer main body portion 110 is released to the outside.

[0088] In this embodiment, the upper surface 112 is the surface facing the positive direction of the Z-axis. Such an upper surface 112 may be exposed so that heat can be directly released to the outside. At this time, the upper surface 112 may extend in the Y-axis direction parallel to the extension direction of the heat transfer main body portion 110. Therefore, the upper surface 112 that releases the heat generated from the bus bar 16 is disposed as close as possible to the bus bar 16, so that the heat can be effectively released.

[0089] Secondly, referring to Figure 7 , in this embodiment, the lower surface 113 of the heat transfer main body portion 110 may be defined as the surface facing the bus bar 16, so that heat is transferred to the heat transfer main body portion 110.

[0090] In the above-described embodiment, the lower surface 113 is the surface facing the negative direction of the Z-axis. Such a lower surface 113 may be arranged to contact the heat dissipation surface 320 of the heat dissipation member 300 described later to receive heat.

[0091] At this time, the lower surface 113 of the heat transfer main body 110 may extend in the Y-axis direction parallel to the extending direction of the heat transfer main body 110. In addition, according to this embodiment, a part of the lower surface 113 may be recessed or protruded.

[0092] For example, a part of the lower surface 113 may protrude in the negative direction of the Z-axis so as to be closer to the current collecting plate 16. In addition, another part of the lower surface 113 may be recessed to correspond to the shape of the bottom 410 of the heat dissipation member frame 400 described later.

[0093] Secondly, in this embodiment, the side surface 114 of the heat transfer main body 110 may be defined as the surface surrounding the side portion of the heat transfer main body 110 between the upper surface 112 and the lower surface 113. In the above-described embodiment, both side surfaces of the side surface 114 facing the X-axis direction are arranged to contact the heat dissipation surface 320 of the heat dissipation member 300 described later together with the lower surface 113 and receive heat.

[0094] In this way, in this embodiment, it is arranged to be in surface contact with the heat dissipation member 300 through the lower surface 113 and the side surface 114 of the heat transfer main body 110, so that the heat transfer area between the two structures can be ensured to be as large as possible.

[0095] On the other hand, the heat transfer main body 110 according to this embodiment and the upper surface 112, the lower surface 113, and the side surface 114 included therein may be appropriately changed in consideration of the shape of the space for arranging the heat transfer main body 110 and the relative combination relationship with other structures. For example, a part of the heat transfer main body 110 may be recessed or protruded.

[0096] Refer to Figures 1 to 4 , a heat transfer member side coupling member hole 111 may be formed in the heat transfer main body 110 of the cooling module 20 according to this embodiment. The heat transfer member side coupling member hole 111 is a structure for coupling the coupling member described later, and may be provided at a position corresponding to the above-described housing side coupling member hole 13. Regarding this, it will be described later together with the coupling member 30.

[0097] Refer to again Figures 4 to 7 , the heat transfer member 100 according to an embodiment of the present invention may include a tube coupling portion 120. The tube coupling portion 120 is a part for coupling the cooling tube 200 described later.

[0098] The tube coupling portion 120 according to this embodiment may be recessed in the form of a groove (hereinafter, referred to as a tube coupling groove) on the upper surface 112 of the heat transfer main body 110 so that the cooling tube 200 can be inserted. Such a tube coupling groove may be arranged along the extending direction of the cooling tube 200.

[0099] At this time, asFigure 3 As shown, the depth of the pipe coupling groove is set to be deeper than the radius of the cooling pipe 200. In other words, when viewed along the extending direction, the part of the cooling pipe 200 inserted into the pipe coupling groove can be larger than the part exposed on the upper surface 112 of the heat transfer main body 110. Therefore, the area where the cooling pipe 200 contacts and exchanges heat with the pipe coupling part 120 can be further increased.

[0100] On the other hand, if the heat transfer main body 110 and the cooling pipe 200 can be combined to transfer heat to each other, the shape of the pipe coupling part 120 is not particularly limited. For example, when the cooling pipe 200 is combined to pass through the inside of the heat transfer main body 110, the pipe coupling part 120 can also be provided in the form of a hole through which the cooling pipe 200 passes.

[0101] Referring to Figure 3 , Figure 6 and Figure 7 , the heat transfer member 100 of the cooling module 20 according to an embodiment of the present utility model may include a peripheral part 130. In this embodiment, the peripheral part 130 is a structure for preventing the heat dissipation member 300 described later from being exposed to the outside between the heat transfer member 100 and the heat dissipation member frame 400.

[0102] In addition, the peripheral part 130 is combined with the side wall part 420 of the heat dissipation member frame 400 in a shape-matching manner, so that it can also perform the function of supplementing the assembly property of the heat transfer member 100 and the heat dissipation member frame 400.

[0103] In this embodiment, the peripheral part 130 may be provided along the periphery of the side part in the X-axis direction of the upper surface 112 of the heat transfer main body 110. Such a peripheral part 130 may be formed to protrude from the heat transfer main body 110 toward the outside direction. Therefore, it is possible to prevent the heat dissipation member 300 between the side surface 114 of the heat transfer main body 110 and the heat dissipation member frame 400 from being exposed to the outside.

[0104] On the other hand, the peripheral part 130 may not be provided according to the characteristics of the heat dissipation member 300 or the position where the heat dissipation member 300 is provided. As an example, when the heat dissipation member 300 is made of a material (such as rubber, etc.) that is elastically in close contact with the heat transfer member 100, the heat dissipation member 300 will not be exposed to the outside, so the peripheral part 130 may not be provided separately.

[0105] As another example, when the heat dissipation member 300 is not provided between the side surface 114 of the heat transfer main body 110 and the heat dissipation member frame 400, the possibility that the heat dissipation member 300 passes through the side surface 114 and is exposed from the upper surface 112 is small, so the peripheral part 130 may not be provided separately.

[0106] Referring to Figures 3 to 5, as described above, at the pipe joint 120 of the cooling module 20 according to an embodiment of the present invention, the cooling pipe 200 can be joined. The cooling pipe 200 can be provided in the form of a pipe through which a specified cooling fluid can flow inside. The cooling fluid is a fluid that absorbs the heat generated in the current collecting plate 16 and releases it to the outside. As an example, the cooling fluid can be water, but is not limited thereto.

[0107] In this embodiment, the cooling pipe 200 can be formed of a water resistance material. As an example, the cooling pipe 200 can be made of aluminum or an aluminum-containing alloy material. This is to prevent the cooling pipe 200 from being corroded by the cooling fluid in the embodiment where the cooling fluid is water.

[0108] According to this embodiment, the cooling pipe 200 can extend in one direction. At this time, the cooling pipe 200 can extend in a direction parallel to the arrangement direction of the plurality of current collecting plates 16. In the above-described embodiment, the cooling pipe 200 can extend in the direction of the Y-axis in which 6 current collecting plates 16 are arranged.

[0109] Therefore, at least a part of the cooling pipe 200 can be as close as possible to any one of the plurality of current collecting plates 16, and thus the heat generated in the current collecting plate 16 can be absorbed as effectively as possible.

[0110] Of course, according to the arrangement of the current collecting plates 16, a part of the cooling pipe 200 can be bent. Furthermore, the cooling pipe 200 can also be arranged to be bent in a zigzag shape on one surface of the current collecting plate 16 so as to perform heat exchange with each current collecting plate 16 through as large an area as possible.

[0111] On the other hand, openings that can communicate with the outside can be provided at both ends of the cooling pipe 200 in the extending direction. At this time, each end of the cooling pipe 200 extends outside the disconnecting module 10, so that the openings can be located outside the disconnecting module 10.

[0112] The inside of the cooling pipe 200 can communicate with the outside through each of the ends. That is, the cooling fluid can flow into the cooling pipe 200 through any one of the ends, and can flow out of the cooling pipe 200 through the other end. Thus, the flow of the cooling fluid for absorbing the heat of the current collecting plate 16 and releasing it to the outside can be controlled.

[0113] In this way, the cooling module 20 according to this embodiment and the battery disconnecting device 1 including the cooling module 20 are arranged such that the cooling fluid flowing through the cooling pipe 200 is fluidly connected to the outside of the present cooling module 20 and the battery disconnecting device 1 including the cooling module 20, so that the loss of the cooling fluid can be prevented and the cooling fluid can be prevented from leaking to other structures of the present cooling module 20 or the present battery disconnecting device 1.

[0114] Referring again to Figure 3 、 Figure 6 and Figure 7 , a heat dissipation member 300 may be provided between the heat transfer member 100 and the current collecting plate 16 of the cooling module 20 according to an embodiment of the present invention. As described above, the heat dissipation member 300 is a structure for transferring heat by heat conduction between the current collecting plate 16 and the heat transfer member 100.

[0115] In this embodiment, the heat dissipation member 300 may be provided to entirely surround the lower surface 113 and the side surface 114 of the above-mentioned heat transfer main body portion 110. In other words, the heat dissipation member 300 may be constituted by a heat conductive layer provided with a prescribed thickness on the lower surface 113 and the side surface 114 of the heat transfer main body portion 110.

[0116] Therefore, the heat dissipation member 300 is in large-area contact with the heat transfer member 100 and the current collecting plate 16, and heat can be transferred through heat conduction. Hereinafter, the surface where the heat dissipation member 300 and the current collecting plate 16 are in contact with each other is referred to as a heat absorption surface 310, and the surface where the heat dissipation member 300 and the heat transfer member 100 are in contact with each other is referred to as a heat dissipation surface 320.

[0117] At this time, the heat dissipation member 300 of the cooling module 20 according to this embodiment may be provided to be airtight between the current collecting plate 16 and the heat transfer member 100 so as to perform effective heat exchange between the current collecting plate 16 and the heat transfer member 100.

[0118] This is because when an air layer having a low thermal conductivity is provided between the current collecting plate 16 and the heat transfer member 100, the heat exchange efficiency between the current collecting plate 16 and the heat transfer member 100 may be reduced due to the air layer.

[0119] For this purpose, the heat dissipation member 300 may be made of a material having a prescribed elasticity so that the heat transfer member 100 and the current collecting plate 16 are airtight. For example, the heat dissipation member 300 may include at least one of thermal conductive rubber, thermal conductive pad, and thermal conductive gel, but is not limited thereto.

[0120] When the current collecting plate 16 and the heat transfer member 100 are brought close to each other and combined during the manufacturing process of the present cooling module 20 or the present battery disconnecting device 1, the elastic heat dissipation member 300 may elastically deform to fill the empty space between the current collecting plate 16 and the heat transfer member 100.

[0121] Alternatively, the heat dissipation member 300 may be made of a material having a specified fluidity, and at least when being set, it deforms and flows according to the shape of the accommodating space, so as to be able to make the heat transfer member 100 and the current collecting plate 16 airtight. For example, the heat dissipation member 300 may include at least one of a thermal conductive gel, a thermal conductive pad, and a thermal conductive rubber, but is not limited thereto.

[0122] When, during the manufacturing process of the present cooling module 20 or the present battery disconnecting device 1, the current collecting plate 16 and the heat transfer member 100 approach and bond to each other, the heat dissipation member 300 having fluidity can flow in and fill the empty space between the current collecting plate 16 and the heat transfer member 100.

[0123] On the other hand, the heat dissipation member 300 may be made of a material having a specified thermal conductivity. As an example, the heat dissipation member 300 may be made of a material having a thermal conductivity of 1 W / mK or more. However, the thermal conductivity of the material forming the heat dissipation member 300 is not particularly limited, as long as in any case, it can improve the thermal conductivity compared with ordinary rubber, gel, or pad.

[0124] At this time, the heat dissipation member 300 may be made of a material having a specified insulation property. This is to prevent the plurality of current collecting plates 16 and the plurality of contactors 14 from being energized with each other through the heat dissipation member 300.

[0125] On the other hand, referring again to Figures 3 to 7 , the cooling module 20 according to an embodiment of the present utility model may include a heat dissipation member frame 400. In this embodiment, the heat dissipation member frame 400 is a frame that covers the outer surface of the heat dissipation member 300 and protects it from external contamination or impact.

[0126] In addition to the above functions, such a heat dissipation member frame 400 can also perform various functions together. For example, the heat dissipation member frame 400 can fix the relative positions between the heat dissipation member 300, the heat transfer member 100, and the current collecting plate 16. Or, the heat dissipation member frame 400 can fix and maintain the overall shape of the heat dissipation member 300.

[0127] For this purpose, the heat dissipation member frame 400 may be made of plastic or the like having a specified rigidity. At this time, the heat dissipation member frame 400 may be made of an insulating material so as to ensure the insulation performance between the current collecting plates 16.

[0128] For example, the heat dissipation member frame 400 can be formed by mixing a material capable of imparting electrical insulation and thermal conductivity into synthetic resins such as polyphenylene sulfide (PPS), polycarbonate (PC), polyamide (PA), polybutylene terephthalate (PBT), and liquid crystal polymer (LCP).

[0129] As an example, the insulating material can be provided as ceramic fillers such as boron nitride (BN), aluminium nitride (AlN), silicon carbide (SiC), magnesium oxide (MgO), and aluminium oxide (Al2O3).

[0130] The heat dissipation member frame 400 of the cooling module 20 according to an embodiment of the present utility model may include a bottom 410. In this embodiment, the bottom 410 can be provided as a plate-like member for covering the lower surface of the outer surface of the heat dissipation member 300 facing the negative direction of the Z axis.

[0131] The bottom 410 can extend parallel to the extension direction of the heat transfer main body portion 110 so as to entirely cover the lower surface of the heat dissipation member 300. In the described embodiment, the bottom 410 extends in the Y-axis direction.

[0132] At this time, contact holes 411 can be provided in the bottom 410 according to this embodiment. The contact holes 411 can expose the heat absorption surface 310 of the heat dissipation member 300 to the outside of the heat dissipation member frame 400.

[0133] In other words, a part of the heat dissipation member 300 can protrude outward through the contact holes 411 of the bottom 410, and the above-mentioned heat absorption surface 310 can be provided on the protruding part. Therefore, the heat absorption surface 310 can be in direct surface contact with the current collecting plate 16.

[0134] At this time, a plurality of contact holes 411 in the bottom 410 can be provided corresponding to the number of the plurality of current collecting plates 16. And each contact hole 411 can have a shape corresponding to the shape of the corresponding current collecting plate 16.

[0135] Thereby, the heat absorption surface 310 of the heat dissipation member 300 can be in surface contact with the current collecting plate 16 with as large an area as possible, and the heat generated in the current collecting plate 16 can be effectively transferred to the heat dissipation member 300 and the heat transfer member 100.

[0136] Refer again to Figures 3 to 7 , the heat dissipation member frame 400 of the cooling module 20 according to an embodiment of the present invention may include a side wall portion 420. The side wall portion 420 may be provided as a plate-like member that covers the side surface of the heat dissipation member 300. In other words, the side wall portion 420 may be provided as a plate-like member that entirely covers the side surface 114 of the heat transfer main body portion 110.

[0137] At this time, the lower portion of the side wall portion 420 may be connected to the bottom portion 410. In addition, the upper portion of the side wall portion 420 may be coupled to the peripheral portion 130 of the heat transfer member 100 in a shape-matching manner. Therefore, the heat dissipation member frame 400 according to this embodiment may entirely cover and protect the outer surface of the heat dissipation member 300. In particular, when the heat dissipation member 300 has a specified fluidity, the overall shape of the heat dissipation member 300 may be maintained and the heat dissipation member 300 may be prevented from flowing outwards.

[0138] Thus, the heat dissipation member 300 of the cooling module 20 according to an embodiment of the present invention is airtight between the heat transfer member 100 and the power collecting plate 16, so that the heat of the power collecting plate 16 is transferred to the heat transfer member 100 through heat conduction. In addition, the heat transferred to the heat transfer member 100 can be effectively released to the cooling pipe 200 and the external air. Therefore, the power collecting plate 16 can be effectively cooled.

[0139] In addition, the cooling module 20 according to this embodiment is arranged to cool the power collecting plate 16 by using a cooling fluid with excellent heat transfer performance. Therefore, the amount of thermal energy that can be cooled per unit volume of the cooling module can be increased, so that it can be provided more compactly than other types of cooling modules that do not use a cooling fluid. Therefore, it can be applied to various types of electronic devices, and the utilization rate of the internal space of the electronic device can be increased.

[0140] On the other hand, refer again to Figures 1 to 3 , the battery disconnecting device 1 according to an embodiment of the present invention may include a coupling member 30. The coupling member 30 is a structure for coupling the disconnecting module 10 and the cooling module 20 to each other.

[0141] According to an embodiment of the present invention, the coupling member 30 may be provided as a screw-shaped member, and a plurality of them may be provided. A part of the plurality of coupling members 30 is penetrated and coupled to the heat transfer member side coupling member hole 111 of the heat transfer member 100 and the housing side coupling member hole 13 described above, so that the cooling module 20 and the housing 12 can be coupled to each other.

[0142] Another part of the plurality of coupling members 30 is penetrated and coupled to the power collecting plate side coupling member hole 17 of the power collecting plate 16 and the housing side coupling member hole 13, so that the power collecting plate 16 and the housing 12 can be coupled to each other.

[0143] Alternatively, another part of the plurality of coupling members 30 is coupled to the busbar-side coupling member holes 17 of the busbar 16 and the contactor 14, so that the two structures can be electrically connected. For this purpose, the coupling member 30 can be made of a metal having a predetermined conductivity.

[0144] On the other hand, in the present embodiment, the coupling member 30 is provided in the form of a screw or a bolt, but the coupling member 30 can be constituted by various structures capable of coupling the disconnect module 10 and the cooling module 20 to each other. Furthermore, if the disconnect module 10 and the cooling module 20 can be self-coupled by shape matching or the like, the coupling member 30 may not be provided separately.

[0145] Hereinafter, with reference to different drawings, a battery disconnecting device according to another embodiment of the present invention will be described. Figure 8 is a perspective view of a battery disconnecting device according to an embodiment of the present invention as viewed from above. Figure 9 is along Figure 8 a cross-sectional view taken along the section line II-II. Figure 10 is a perspective view of a cooling module according to another embodiment of the present invention as viewed from below. Figure 11 and Figure 12 are exploded perspective views of a cooling module according to another embodiment of the present invention as viewed from different angles.

[0146] Referring to Figure 8 , there is disclosed a battery disconnecting device 1' according to another embodiment of the present invention. The battery disconnecting device 1' according to the present embodiment may include a disconnect module 10, a cooling module 20', and a coupling member 30.

[0147] At this time, the disconnect module 10 and the coupling member 30 of the battery disconnecting device 1' according to the present embodiment may be provided in the same manner as the disconnect module and the coupling member of the battery disconnecting device according to an embodiment of the present invention, and a detailed description thereof will be omitted. A detailed description of the cooling module 30' according to the present embodiment will be given. Figures 1 to 7 Referring to

[0148] Referring to Figures 8 to 12 , the cooling module 20' according to another embodiment of the present invention may include a heat transfer member 100, a cooling pipe 200, and a heat dissipation member 300. In the present embodiment, the heat transfer member 100 is a structure that releases the heat generated in the busbar 16 to the outside and protects the heat dissipation member 300 described later from external contamination or impact.

[0149] In the present embodiment, the heat transfer member 100 may include a heat transfer main body portion 110 and a pipe coupling portion 120. The heat transfer main body portion 110 may be provided in the form of a block extending in one direction.

[0150] In addition, the lower surface of the heat transfer main body 110 may be located on the upper surface of the current collecting plate 16. In this embodiment, the lower surface of the heat transfer main body 110 is in surface contact with the upper surface of the current collecting plate 16. At this time, the heat transfer main body 110 may be made of a material having a specified heat transfer rate so as to be able to effectively release heat. For example, the heat transfer main body 110 may be made of aluminum or an aluminum-containing alloy material.

[0151] According to this embodiment, the heat transfer main body 110 may extend in the Y-axis direction parallel to the direction in which a plurality of current collecting plates 16 are arranged. Therefore, at least a part of the heat transfer main body 110 is arranged as close as possible to any one of the plurality of current collecting plates 16, and the heat generated in the current collecting plate 16 can be effectively absorbed and released to the outside.

[0152] Of course, the shape of the heat transfer main body 110 may be appropriately changed in consideration of the installation space or the combination relationship with other structures. For example, a part of the heat transfer main body 110 may be recessed or protruded.

[0153] Refer to Figure 9 and Figure 12 , a pipe coupling part 120 may be provided on one surface of the heat transfer main body 110. Here, the one surface may be the lower surface facing the current collecting plate 16. In this embodiment, the pipe coupling part 120 is a part for coupling the cooling pipe 200 described later.

[0154] At this time, as shown in the figure, according to this embodiment, the pipe coupling part 120 may be provided in the form of a groove (hereinafter, referred to as a pipe coupling groove) for inserting the cooling pipe 200 and the heat dissipation member 300 surrounding the inserted cooling pipe 200. In addition, such a pipe coupling groove may be provided along the extending direction of the cooling pipe 200.

[0155] In this way, in this embodiment, a pipe coupling groove is provided on the lower surface of the heat transfer main body 110 facing the current collecting plate 16, so that one side portion of the heat dissipation member 300 surrounding the cooling pipe 200 is in surface contact with the current collecting plate 16, and the other side portion is surrounded by the heat transfer main body 110 and may not be exposed to the outside.

[0156] Therefore, the heat dissipation member 300 can be protected from external contamination and impact by the heat transfer main body 110. Alternatively, the heat dissipation member 300 can be fixed in position by the heat transfer main body 110 so as not to be separated from the cooling pipe 200. Or, when the heat dissipation member 300 has a specified fluidity, the heat dissipation member 300 can be fixed and maintained in its overall shape by the heat transfer main body 110.

[0157] On the other hand, in the present embodiment, the tube coupling part 120 may be provided in the form of a groove, but the form of the tube coupling part 120 is not particularly limited as long as the cooling tube 200 can be coupled. For example, when the cooling tube 200 passes through the inside of the heat transfer main body part 110 and is coupled, the tube coupling part 120 may be provided in the form of penetrating and coupling the cooling tube 200.

[0158] Referring to Figure 9 and Figure 11 , the heat transfer member 100 of the cooling module 20' according to another embodiment of the present utility model may include a heat sink 130. The heat sink 130 is for effectively releasing the heat transferred to the power collecting plate 16 of the heat transfer main body part 110.

[0159] Such a heat sink 130 may be provided on the outer side surface of the heat transfer main body part 110 that is exposed to the outside. In the described embodiment, the heat sink 130 is provided on the upper surface of the heat transfer main body part 110.

[0160] The heat sink 130 may have a structure for effectively releasing heat. To this end, the heat sink 130 may be arranged to be able to expand the area of the outer side surface of the heat transfer member 100.

[0161] As shown in the figure, the heat sink 130 may be provided as a plurality of plate-like members having a narrow thickness. In addition, some of the plurality of heat sinks 130 may be spaced apart in the X-axis direction and arranged parallel to each other, and the remaining heat sinks may be arranged in the Y-axis direction in a manner intersecting the X-axis direction. The structure and arrangement of such a heat sink 130 may be appropriately changed according to requirements.

[0162] Here, referring to Figures 9 to 12 , in the tube coupling part 120 of the heat transfer member 100 according to the present embodiment, the cooling tube 200 can be coupled. At this time, the cooling tube 200 may be configured similarly to the cooling tube 200 ( Figure 1 shown) according to the above embodiment.

[0163] At this time, referring to Figure 9 , the cross-section perpendicular to the extending direction of the cooling tube 200 of the cooling tube 200 according to the present embodiment may have a quadrilateral shape. Therefore, the area of the outer side surface of the cooling tube 200 becomes larger compared to the size, so that external heat can be effectively transferred to the cooling fluid flowing through the cooling tube 200.

[0164] At this time, in the cross-section of the cooling pipe 200, the width in the direction parallel to one surface of the current collecting plate 16 (i.e., the width in the X-axis direction) can be set to be greater than the width in the direction perpendicular to or inclined to one surface of the current collecting plate 16 (i.e., the width in the Z-axis direction). Therefore, the area of the surfaces of the cooling pipe 200 and the current collecting plate 16 facing each other becomes larger, so that the heat of the current collecting plate 16 can be transferred to the cooling pipe 200.

[0165] Referring again to Figures 9 to 12 , as described above, the heat dissipation member 300 of the cooling module 20' according to an embodiment of the present invention can be arranged to surround the outer peripheral portion of the cooling pipe 200. The heat dissipation member 300 can integrally surround the portion of the outer peripheral portion of the cooling pipe 200 that is joined to the pipe joint portion 120. At this time, the heat dissipation member 300 can be arranged to make the heat transfer member 100 and the current collecting plate 16 airtight.

[0166] More specifically, in the present embodiment, the heat dissipation member 300 is arranged to make the pipe joint groove airtight. Thereby, the heat exchange between the current collecting plate 16, the heat transfer member 100, and the cooling pipe 200 can be effectively carried out.

[0167] This is because when an air layer with low thermal conductivity is provided between the current collecting plate 16 and the heat transfer member 100, the heat transfer rate between the two structures can be reduced thereby.

[0168] For this purpose, the heat dissipation member 300 can be made of a material having a predetermined elasticity to make the heat transfer member 100 and the current collecting plate 16 airtight. For example, the heat dissipation member 300 can be made of thermal conductive rubber or thermal conductive pad, but is not limited thereto.

[0169] Alternatively, the heat dissipation member 300 can be made of a material having a predetermined fluidity that can deform and flow at least when set according to the shape between the heat transfer member 100 and the current collecting plate 16, so as to make the heat transfer member 100 and the current collecting plate 16 airtight. For example, the heat dissipation member 300 can be made of thermal conductive gel or thermal conductive pad, but is not limited thereto.

[0170] On the other hand, the heat dissipation member 300 can be made of a material having a predetermined thermal conductivity. As an example, the heat dissipation member 300 can be made of a material having a thermal conductivity of 1 W / mK or more. However, the thermal conductivity of the material forming the heat dissipation member 300 is not particularly limited as long as it can improve the thermal conductivity compared with ordinary rubber, gel, or pad in any case.

[0171] At this time, the heat dissipation member 300 may be made of a material having a specified insulation property. This is to prevent the plurality of current collecting plates 16 and the plurality of contactors 14 from being energized with each other through the heat dissipation member 300.

[0172] According to the present embodiment, an endothermic surface that is in surface contact with the current collecting plate 16 may be provided on the lower side portion of the heat dissipation member 300, and a heat dissipation surface that is in surface contact with the inner surface of the pipe coupling groove may be provided on the upper portion and the side portion of the heat dissipation member 300.

[0173] Therefore, a part of the heat transferred from the current collecting plate 16 to the heat dissipation member 300 through the endothermic surface may be transferred to the cooling pipe 200, and the remaining part is released to the outside through the heat transfer member 100.

[0174] In addition, the cooling module 20' according to the present embodiment is different from the cooling module 20 according to the above embodiment, and a separate heat dissipation member frame may not be provided, so that the structure of the cooling module can be set more compactly. As a result, the manufacturing cost of the cooling module can be reduced and the space utilization rate can be improved.

[0175] As described above, an embodiment of the present invention has been described, but the idea of the present invention is not limited to the embodiments described in this specification. Those skilled in the art who understand the idea of the present invention can easily propose other embodiments by addition, change, deletion, addition, etc. within the same idea range, but this also belongs to the idea range of the present invention.
