Detailed Description
The present utility model will now be more fully described by way of examples with reference to the accompanying drawings.
As shown in fig. 2 and 3, the present embodiment provides a battery pack 100, which includes a housing 120, and a plurality of electric cells 110 and a heat exchanging device 200 disposed inside the housing 120. The heat exchange device 200 is located between adjacent cells 110, and the cells 110 and the heat exchange device 200 are alternately arranged. Specifically, the heat exchanging device 200 is interposed between two adjacent cells 110 in a substantially vertical posture, and extends in the height direction H.
The battery pack 100 is applicable to electric vehicles, electric bicycles, various high-power electric appliances, and the like. It should be understood by those skilled in the art that the "battery pack 100" herein refers to a generic term for forming various forms of batteries in a package shape, a box shape, a column shape, etc., rather than a single-finger package shape.
As shown in fig. 4-7, the heat exchange device 200 in the battery pack 100 provided in this embodiment includes two opposite side plates, the two side plates are a first side plate 210 and a second side plate 220, and a plurality of supporting portions 230 located between the first side plate 210 and the second side plate 220, and upper and lower ends of the first side plate 210 and the second side plate 220 are connected by end plates 240, wherein a flow channel 250 through which a heat exchange medium flows is formed between two adjacent supporting portions 230.
The plurality of supporting parts 230 are arranged along the height direction H of the side plates, the supporting parts 230 include a first portion 231, a middle portion 233 and a second portion 232, the middle portion 233 is connected to the first portion 231 and the second portion 232, respectively, and is located between the first portion 231 and the second portion 232, the first portion 231 is substantially perpendicularly connected to the first side plate 210, the second portion 232 is substantially perpendicularly connected to the second side plate 220, the first portion 231 and the second portion 232 have a space in the height direction H, and the first portion 231 and the second side plate 220 have a space therebetween, and the second portion 232 and the first side plate 210 have a space therebetween.
When the battery cell 110 expands in the thickness direction (X direction as shown in fig. 3) thereof during use, the heat exchange device 200 is compressively deformed, and the first side plate 210 and the second side plate 220 approach each other, thereby driving the first portion 231 and the second portion 232 connected to the first side plate 210 and the second side plate 220, respectively, to move toward each other, and since the first portion 231 and the second side plate 220 have a distance, the second portion 232 has a distance from the first side plate 210, and at the same time, the first portion 231 and the second portion 232 have a distance in the height direction H of the side plates, so that the intermediate portion 233 connected between the first portion 231 and the second portion 232 is adaptively deformed; the first portion 231 and the second portion 232 are substantially perpendicular to the side plates, so that the support is formed along the direction in which the first side plate 210 and the second side plate 220 approach each other, and when the first portion 231 abuts against the second side plate 220 or the second portion 232 abuts against the first side plate 210, the first side plate 210 and the second side plate 220 do not continue to approach each other, so that the heat exchange device 200 is not crushed, the flow channel 250 between two adjacent support portions 230 is not closed, and still can remain clear, as shown in fig. 6 to 7. In addition, the supporting part 230 has a simple structure, does not have excessively complex connection relationship, and is easy to process and install.
By "substantially perpendicular" is meant that the angle of the first side plate 210 to the first portion 231 and the angle of the second side plate 220 to the second portion 232 may be offset by 90 degrees, such as between 85 degrees and 95 degrees, as will be appreciated by those skilled in the art, such minor angular offsets do not affect the support of the first side plate 220 and the first side plate 210 by the first portion 231 and the second portion 232.
In this embodiment, the first portion 231 and the second portion 232 are flat plates. Since the first portion 231 and the second portion 232 are substantially perpendicular to the side plates, when the first side plate 210 and the second side plate 220 are close to each other, the first portion 231 and the second portion 232 are respectively pressed parallel to the extending direction of the first portion 231 and/or the second portion 232, and the flat shape is more helpful for the first portion 231 and/or the second portion 232 to exert a supporting effect, so that the first portion 231 and/or the second portion 232 are not pressed and deformed, thereby ensuring the width of the flow channel 250. However, the present utility model is not limited thereto, and the first portion 231 or the second portion 232 may be formed in a substantially elongated shape, and may also function as a support when the first side plate 210 and the second side plate 220 are close to each other.
In this embodiment, the middle portion 233 is flat. When the intermediate portion 233 is formed in a flat plate shape, the intermediate portion 233 forms corners with the first portion 231 and the second portion 232, respectively, and when the first side plate 210 and the second side plate 220 are brought close to each other, the angles of the corners formed by the intermediate portion 233 and the first portion 231 and the second portion 232 are changed, and the relative positions between the intermediate portion 233 and the first portion 231 and the second portion 232 are twisted, thereby absorbing deformation generated by the first side plate 210 and the second side plate 220 being brought close to each other. In other embodiments, as shown in fig. 9, the middle portion 233 may also be undulating. When the middle portion 233 is waved, not only deformation of the first and second side plates 210 and 220 caused by approaching each other can be absorbed by changing the angle of the corner formed by the middle portion 233 and the first and second portions 231 and 232, but also deformation of the first and second side plates 210 and 220 caused by approaching each other can be absorbed by compressing the middle portion 233 itself while twisting. The middle portion 233 functions to absorb deformation generated by the first and second side plates 210 and 220 approaching each other through deformation thereof, and one skilled in the art can select the shape of the middle portion 233 according to actual needs.
As shown in fig. 5, the first portion 231 is bent toward the middle portion 233, a first connection portion 234 is formed at the bent portion, the first portion 231 is connected to the middle portion 233 through the first connection portion 234, the second portion 232 is bent toward the middle portion 233, a second connection portion 235 is formed at the bent portion, and the second portion 232 is connected to the middle portion 233 through the second connection portion 235.
The first portion 231 and the second portion 232 are respectively connected with the middle portion 233, and since the angle of the corner formed by the middle portion 233 and the first portion 231 and the second portion 232 is changed when the first side plate 210 and the second side plate 220 are close to each other, the first connection portion 234 and/or the second connection portion 235 is formed by bending the first portion 231 and/or the second portion 232 toward the middle portion 233, so that the whole structure of the support 230 has toughness, is suitable for absorbing deformation, and avoids the connection between the first portion 231 and the middle portion 233 and/or the second portion 232 and the middle portion 233 from being too stiff, and is broken when the angle of the corner formed by the middle portion 233 and the first portion 231 and/or the second portion 232 is changed.
In the present embodiment, the first connecting portion 234 and the second connecting portion 235 are arc-shaped. When the first connection portion 234 and/or the second connection portion 235 are provided in an arc shape, the connection transition between the first portion 231 and/or the second portion 232 and the intermediate portion 233 is more gentle, and breakage is further prevented.
In other embodiments, the first and second connection parts 234 and 235 are flat plates, i.e., the first portion 231, the first connection part 234, and the middle portion 233 are formed as three-stage folding lines, or the second portion 232, the second connection part 235, and the middle portion 233 are formed as three-stage folding lines; alternatively, the first and second connection portions 234 and 235 may be formed in an angular shape, i.e., the first and middle portions 231 and 233, and the second and middle portions 232 and 233 are formed as two-stage folding lines, respectively. The first connection portion 234 and/or the second connection portion 235 may be provided in a flat plate shape, an arc shape, or an angle shape according to actual needs by those skilled in the art.
In the present embodiment, as shown in fig. 5, the first portions 231 of the adjacent two support portions 230 are close to each other and the second portions 232 are distant from each other in a direction away from the first side plate 210 connecting the first portions 231. Since the second portions 232 are spaced apart from each other, a sufficient space is left for the adjacent support portions 230 to deform, and the adjacent support portions 230 do not contact each other after being pressed, thereby further ensuring the smoothness of the flow passage 250.
In other embodiments, as shown in fig. 8 and 9, two adjacent support portions 230 may be arranged substantially in parallel, that is, arranged such that: the distance between the first portions 231 of the adjacent two support portions 230 and the distance between the second portions 232 of the adjacent two support portions 230 are substantially equal. By "substantially equal" is meant herein that the difference in distance between the two is within a range such that adjacent two supports 230 assume a substantially parallel pattern. Adjacent supporting portions 230 are arranged substantially in parallel in the height direction H of the side plate, so that the mounting process of the supporting portions 230 is more convenient, and the processing and manufacturing efficiency is improved.
The two end plates 240 of the heat exchange device 200 are disposed between the first side plate 210 and the second side plate 220 and at both ends of the two side plates in the height direction H, respectively, and the end plates 240 connect the first side plate 210 and the second side plate 220, respectively. The end plates 240 are disposed at both ends of the two side plates in the height direction H, so that the support portions 230 at the highest and lowest positions disposed along the height direction H of the side plates can also form the flow passages 250 with the end plates 240, and in addition, the support portions 230 at the highest and lowest positions disposed along the height direction H of the side plates are protected from damage by the arrangement of the end plates 240.
The support 230 is preferably integrally formed. The support part 230 is integrally formed, so that the connecting process of the first part 231 and the middle part 233 and the connecting process of the second part 232 and the middle part 233 are saved, the structure of the support part 230 is complete, and the cracking at the connecting position during the deformation absorption is avoided.
Specifically, the support portion 230 in this embodiment is made of an aluminum alloy, and is integrally formed into an S-shape from an aluminum alloy plate. The aluminum alloy has good plasticity and corrosion resistance, is suitable for molding a specific shape and suitable for circulation of heat exchange media, and has good toughness and is suitable for bearing compression deformation. In alternative embodiments, the support 230 may be formed of steel alloys or other more ductile materials.
The heat exchange medium in this embodiment may be a heat exchange medium commonly used in the battery field such as water, and will not be described herein. The heat exchange medium is used to remove heat from the battery pack 100 when the battery pack 100 has a cooling requirement, and is used to provide heat to the battery pack 100 when the battery pack 100 has a heating requirement.
It should be understood by those skilled in the art that the present embodiment illustrates only one use of the heat exchanging apparatus 200, but the present utility model is not limited thereto, and the heat exchanging apparatus 200 of the present utility model may be applied to other apparatuses and devices requiring heat exchange.
