Description

Technical Field

[0001] The present disclosure relates to the field of battery technology, and in particular to a lithium battery module with high heat dissipation and dust resistance and a household energy storage device. Background Art

[0002] Energy storage battery boxes, specifically energy storage battery containers, are devices that encapsulate large-capacity energy storage battery modules within a container. They combine the energy storage capabilities of energy storage batteries with the portability and standardization of containers. Because battery boxes contain battery packs, which generate heat during operation, heat dissipation holes are typically provided on the walls of the battery boxes to improve the heat dissipation performance of the battery packs.

[0003] For example, Chinese patent application number CN202310458706.1 discloses a new type of energy storage battery box, including a box body, a fan is provided on the outer peripheral side of the box body, the fan is connected to a refrigeration device, and a plurality of first heat dissipation holes are provided on the outer peripheral side of the box body. The first heat dissipation holes and the fan are located on different sides of the box body, and the first heat dissipation holes are evenly arranged on the outer peripheral side of the box body.

[0004] However, the structural design of the above energy storage battery box has the following problems during use:

[0005] The aforementioned energy storage battery case has first heat dissipation holes on the outer periphery of the case body. A fan transports heat from the case body to the first heat dissipation holes, thereby reducing the heat inside the battery case. However, because the first heat dissipation holes are elongated and have a large area, impurities such as dust and mosquitoes can easily enter the case through the first heat dissipation holes, potentially causing a battery short circuit.

[0006] Therefore, there is an urgent need for a structural design that has good heat dissipation performance and can prevent impurities from entering the box. Utility Model Content

[0007] The purpose of the present disclosure is to overcome the deficiencies in the prior art and provide a high-heat dissipation and dust-proof lithium battery module and a household energy storage device with good heat dissipation performance and the ability to prevent impurities from entering the box.

[0008] The purpose of this disclosure is achieved through the following technical solutions:

[0011] The lithium battery module also includes a dustproof part, which is connected to the inner side of the box body. The dustproof part is provided with a plurality of second heat dissipation holes arranged at intervals. The first heat dissipation holes and the second heat dissipation holes are arranged correspondingly. The cooling fan is connected to the dustproof part. The cooling fan is arranged towards the first heat dissipation holes and the second heat dissipation holes. There is a preset angle between the first heat dissipation holes and the second heat dissipation holes so that the first heat dissipation holes and the second heat dissipation holes are staggered.

[0012] In one embodiment, the first heat dissipation hole and the second heat dissipation hole are arranged perpendicular to each other.

[0013] In one embodiment, the first heat dissipation holes are arranged in an array along the horizontal direction, and the second heat dissipation holes are arranged in an array along the vertical direction.

[0015] In one embodiment, the length of the first heat dissipation hole is greater than the length of the second heat dissipation hole.

[0016] In one embodiment, the high heat dissipation and dustproof lithium battery module also includes a fastener, the box body is provided with a first connecting hole, the dustproof part is provided with a second connecting hole, and the fastener passes through the first connecting hole and the second connecting hole in sequence to connect the box body and the dustproof part.

[0017] In one embodiment, the high heat dissipation and dustproof lithium battery module also includes a screw connection part, the dustproof part is provided with a first screw connection hole, and the cooling fan is provided with a second screw connection hole. The screw connection part passes through the first screw connection hole and the second screw connection hole in sequence to screw the cooling fan and the dustproof part.

Furthermore, a predetermined angle is formed between the first and second heat dissipation holes, i.e., the first and second heat dissipation holes are staggered, reducing the flow area between the first and second heat dissipation holes. When impurities such as dust or mosquitoes pass through the first heat dissipation holes, they are easily blocked by the corresponding second heat dissipation hole walls, making it difficult for impurities to enter the battery module and thus preventing battery short circuits.

[0031] The present disclosure provides a high-heat-dissipation and dust-proof lithium battery module, comprising a box, a battery pack, a cooling fan and a dustproof member, wherein the battery pack is installed in the box, a plurality of first heat dissipation holes arranged at intervals are opened on the circumference of the box, the dustproof member is connected to the inner side of the box, a plurality of second heat dissipation holes arranged at intervals are opened on the dustproof member, the first heat dissipation holes and the second heat dissipation holes are arranged correspondingly, the cooling fan is connected to the dustproof member, the cooling fan is arranged toward the first heat dissipation holes and the second heat dissipation holes, and there is a preset angle between the first heat dissipation holes and the second heat dissipation holes so that the first heat dissipation holes and the second heat dissipation holes are staggered.

[0032] The aforementioned high-heat and dust-proof lithium battery module features a plurality of spaced-apart first heat dissipation holes on the periphery of the housing, a plurality of spaced-apart second heat dissipation holes on the dustproof member, and a cooling fan mounted on the dustproof member and oriented toward the first and second heat dissipation holes, thereby improving heat dissipation within the battery module. Furthermore, a predetermined angle is formed between the first and second heat dissipation holes, i.e., the first and second heat dissipation holes are staggered, reducing the flow area between the first and second heat dissipation holes. When impurities such as dust or mosquitoes pass through the first heat dissipation holes, they are easily blocked by the corresponding second heat dissipation hole walls, making it difficult for impurities to enter the battery module and thus preventing battery short circuits.

[0033] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0034] like Figures 1 to 3As shown, a high-heat-dissipation and dust-proof lithium battery module 10 of an embodiment includes a case 100, a battery pack 200, a cooling fan 300 and a dustproof member 400. The battery pack 200 is installed in the case 100. A plurality of first heat dissipation holes 110 arranged at intervals are opened on the circumference of the case 100. The dustproof member 400 is connected to the inner side of the case 100. The dustproof member 400 is opened with a plurality of second heat dissipation holes 410 arranged at intervals. The first heat dissipation holes 110 and the second heat dissipation holes 410 are arranged correspondingly. The cooling fan 300 is connected to the dustproof member 400. The cooling fan 300 is arranged towards the first heat dissipation holes 110 and the second heat dissipation holes 410. There is a preset angle between the first heat dissipation holes 110 and the second heat dissipation holes 410 so that the first heat dissipation holes 110 and the second heat dissipation holes 410 are staggered. Specifically, the first heat dissipation holes 110 and the second heat dissipation holes 410 are not arranged in parallel, but are staggered, thereby reducing the flow area between the first heat dissipation holes 110 and the second heat dissipation holes 410 .

[0035] In this embodiment, first heat dissipation holes 110 are provided on both sides of the box body 100, and there are multiple first heat dissipation holes 110 on each side. There are two dustproof parts 400, and the two dustproof parts 400 are respectively arranged on both sides of the box body 100. The cooling fan 300 is connected to one of the dustproof parts, and the cooling fan 300 is arranged toward the first heat dissipation holes 110 and the second heat dissipation holes 410 on the other side, so that the cooling fan 300 transfers the heat of the battery pack in the middle to the other dustproof part 400, and discharges it through the first heat dissipation holes 110 and the second heat dissipation holes 120. Furthermore, a preset angle exists between the first heat dissipation holes 110 and the corresponding second heat dissipation holes 410, so that the first heat dissipation holes 110 and the second heat dissipation holes 410 are arranged in an interlaced manner, that is, the first heat dissipation holes 110 and the second heat dissipation holes 410 are not arranged in parallel. This reduces the flow area between the first heat dissipation holes 110 and the second heat dissipation holes 410. Dust or mosquitoes passing through the first heat dissipation holes 110 are easily blocked by the hole walls of the second heat dissipation holes 410, thereby improving the dust and insect resistance of the battery module. Furthermore, the dustproof member 400 is a dustproof net.

[0036] The aforementioned high-heat-dissipation and dust-proof lithium battery module 10 has a plurality of first heat dissipation holes 110 spaced apart on the periphery of the housing 100, a plurality of second heat dissipation holes 410 spaced apart on the dustproof member 400, and a cooling fan 300 mounted on the dustproof member 400 and oriented toward the first heat dissipation holes 110 and the second heat dissipation holes 410, thereby improving heat dissipation within the battery module. Furthermore, a predetermined angle is formed between the first heat dissipation holes 110 and the second heat dissipation holes 410, i.e., the first heat dissipation holes 110 and the second heat dissipation holes 410 are staggered, reducing the flow area between the first heat dissipation holes 110 and the second heat dissipation holes 410. When impurities such as dust or mosquitoes pass through the first heat dissipation holes 110, they are easily blocked by the corresponding second heat dissipation holes 410, making it difficult for the impurities to enter the battery module, thereby preventing battery short circuits.

[0037] like Figure 1 and Figure 3 As shown, in one embodiment, the first heat dissipation holes 110 and the second heat dissipation holes 410 are arranged perpendicular to each other. In this embodiment, the first heat dissipation holes 110 and the second heat dissipation holes 410 are arranged perpendicular to each other, that is, the preset angle between the first heat dissipation holes 110 and the second heat dissipation holes 410 is 90 degrees, so that the first heat dissipation holes 110 and the second heat dissipation holes 410 are staggered to reduce the flow area between the first heat dissipation holes 110 and the second heat dissipation holes 410.

[0038] like Figure 1 and Figure 3 As shown, in one embodiment, the first heat dissipation holes 110 are arranged in a horizontal array, and the second heat dissipation holes 410 are arranged in a vertical array. In this embodiment, the preset angle between the first heat dissipation holes 110 and the second heat dissipation holes 410 is 90 degrees, so that the first heat dissipation holes 110 and the second heat dissipation holes are arranged in an alternating manner.

[0039] In one embodiment, the first heat dissipation holes 110 are arranged in a vertical array, and the second heat dissipation holes 410 are arranged in a horizontal array. In this embodiment, the preset angle between the first heat dissipation holes 110 and the second heat dissipation holes 410 is 90 degrees, so that the first heat dissipation holes 110 and the second heat dissipation holes are arranged in an alternating manner.

[0040] In another embodiment, the first heat dissipation hole 110 is tilted on the box body 100, and the second heat dissipation hole 410 is tilted on the dustproof part 400. The inclination direction of the first heat dissipation hole 110 is opposite to the tilt direction of the second heat dissipation hole 410, so that the first heat dissipation hole 110 and the second heat dissipation hole 410 are staggered.

[0041] In one embodiment, the length of the first heat dissipation hole 110 is greater than the length of the second heat dissipation hole 410. In this embodiment, the length of the first heat dissipation hole 110 is greater than the length of the second heat dissipation hole 410, so that the multiple second heat dissipation holes 410 on the dustproof member 400 are more densely packed, further reducing the flow area between the first heat dissipation holes 110 and the second heat dissipation holes 410, thereby making it more difficult for impurities such as dust and mosquitoes to enter the interior of the housing 100 through the dustproof member 400.

[0042] like Figure 2 As shown, in one embodiment, the high-heat dissipation and dust-proof lithium battery module further includes a fastener 500. The housing 100 is provided with a first connection hole, and the dustproof member 400 is provided with a second connection hole 420. The fastener 500 sequentially passes through the first connection hole and the second connection hole 420 to connect the housing 100 to the dustproof member 400. In this embodiment, the fastener 500 is a bolt to thread the housing 100 and the dustproof member 400 to facilitate assembly and disassembly.

[0043] In one embodiment, the high-heat dissipation and dust-proof lithium battery module further includes a screw connection member. The dustproof member 400 has a first screw connection hole, and the cooling fan 300 has a second screw connection hole. The screw connection member sequentially passes through the first screw connection hole and the second screw connection hole to screw the cooling fan 300 to the dustproof member 400. In this embodiment, the screw connection member is a bolt, which screws the cooling fan 300 to the dustproof member 400 to facilitate assembly and disassembly.

[0044] like Figure 3 As shown, in one embodiment, the dustproof member 400 is provided with a receiving slot 430, and the second heat dissipation hole 410 is provided on the slot wall of the receiving slot 430. In this embodiment, the second heat dissipation hole 410 is provided on the bottom wall of the receiving slot 430. When impurities such as dust or mosquitoes pass through the first heat dissipation hole 110, they are easily blocked by the hole wall of the second heat dissipation hole 410 and fall into the receiving slot 430, making it easier to clean them later.

[0045] like Figure 1 As shown, in one embodiment, the first heat dissipation hole 110 is a waist-shaped hole. In other embodiments, the first heat dissipation hole 110 can also be a circular or rectangular hole.

[0046] like Figure 3 As shown, in one embodiment, the second heat dissipation hole 410 is a waist-shaped hole. In other embodiments, the second heat dissipation hole 410 can also be a circular or rectangular hole.

[0047] The present application also provides a household energy storage device, comprising the high heat dissipation and dustproof lithium battery module 10 described in any of the above embodiments.

[0048] Compared with the prior art, the present disclosure has at least the following advantages:

[0049] The aforementioned high-heat-dissipation and dust-proof lithium battery module 10 has a plurality of first heat dissipation holes 110 spaced apart on the periphery of the housing 100, a plurality of second heat dissipation holes 410 spaced apart on the dustproof member 400, and a cooling fan 300 mounted on the dustproof member 400 and oriented toward the first heat dissipation holes 110 and the second heat dissipation holes 410, thereby improving heat dissipation within the battery module. Furthermore, a predetermined angle is formed between the first heat dissipation holes 110 and the second heat dissipation holes 410, i.e., the first heat dissipation holes 110 and the second heat dissipation holes 410 are staggered, reducing the flow area between the first heat dissipation holes 110 and the second heat dissipation holes 410. When impurities such as dust or mosquitoes pass through the first heat dissipation holes 110, they are easily blocked by the corresponding second heat dissipation holes 410, making it difficult for the impurities to enter the battery module, thereby preventing battery short circuits.

[0050] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art could make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the present patent shall be determined by the appended claims.
