[0036] Typical embodiments embodying the features and advantages of the present utility model will be described in detail in the following description. It should be understood that the present utility model can have various changes in different embodiments, all of which do not depart from the scope of the present utility model, and the descriptions and drawings therein are for illustrative purposes in essence and are not used to limit the present utility model.
[0037] In the following description of different exemplary embodiments of the present utility model, reference is made to the accompanying drawings, which form a part of the present utility model and in which are shown, by way of example, different exemplary structures, systems, and steps that can implement various aspects of the present utility model. It should be understood that other specific solutions of components, structures, exemplary devices, systems, and steps can be used and structural and functional modifications can be made without departing from the scope of the present utility model. Moreover, although terms such as "above", "between", "within", etc. may be used in this specification to describe different exemplary features and elements of the present utility model, these terms are used herein only for convenience, for example, according to the directions of the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional direction of the structure to fall within the scope of the present utility model.
[0038] Referring to Figure 1 , which representatively shows a three-dimensional structural schematic diagram of a partial structure of the battery device proposed by the present utility model, in which a combined structure of one heat exchange component 200 of the heat exchange device proposed by the present utility model and two battery rows 100 is specifically shown. In this exemplary embodiment, the heat exchange device proposed by the present utility model is described by taking an in-vehicle battery as an example. It is easy for those skilled in the art to understand that in order to apply the relevant designs of the present utility model to other types of battery devices, various modifications, additions, substitutions, deletions, or other changes are made to the following specific embodiments, and these changes are still within the scope of the principle of the heat exchange device proposed by the present utility model.
[0039] As Figure 1 shown, in an embodiment of the present utility model, the heat exchange device proposed by the present utility model is adapted to exchange heat with the battery row 100, and the heat exchange device includes a heat exchange component 200 and a heat insulation member 300. With reference to Figures 2 to 4 , Figure 2 representatively shows Figure 1 a three-dimensional exploded schematic diagram, in which specifically the heat exchange component 200 is separated from the battery row 100; Figure 3 representatively shows a planar schematic diagram of the heat exchange component 200; Figure 4 representatively shows a cross-sectional view taken along the Figure 3 line A-A in
[0040] As Figures 1 to 3As shown in the figure, the battery row 100 includes at least two batteries 110 arranged along the first direction X. The heat exchange component 200 is adapted to exchange heat with at least two batteries 110 of the battery row 100. The heat exchange component 200 has a first surface 201 facing the battery 110, that is, the heat exchange component 200 exchanges heat with the battery 110 through this first surface 201. The so-called heat exchange by contact can be understood as direct contact or indirect contact. The heat exchange component 200 has a cavity for accommodating a heat exchange medium inside, and the heat exchange component 200 is provided with a medium inlet 210 communicating with the cavity. The heat insulation member 300 is at least partially located between the battery 110 and the heat exchange component 200. For example, the heat insulation member 300 can be arranged on the first surface 201 of the heat exchange component 200, or can also be arranged on the side of the battery 110 facing the heat exchange component 200. On this basis, for the convenience of understanding and description, a target battery 120 is defined in this specification. The target battery 120 refers to the battery 110 in the battery row 100 that is closer to the medium inlet 210 than other batteries 110. For a battery row 100, the target battery 120 can be one, that is, the one closest to the medium inlet 210, or the target battery 120 can also be two or more, that is, multiple batteries 110 that are relatively closer to the medium inlet 210 than other batteries 110. Among them, taking the plane where the first surface 201 of the heat exchange component 200 is located as the reference plane, on this reference plane, the orthographic projection of the heat insulation member 300 is within the orthographic projection range of the target battery 120, and the orthographic projection of the heat insulation member 300 occupies at least a part of the orthographic projection of the target battery 120, that is, the orthographic projection of the heat insulation member 300 can occupy the entire area of the orthographic projection of the target battery 120, or can also occupy a part or at least two parts of the area included in the orthographic projection of the target battery 120. Through the above structural design, the utility model can use the heat insulation member 300 to block the heat exchange between the heat exchange component 200 and the battery 110 in the area where it is located, avoid a large temperature difference between the battery 110 close to the medium inlet 210 and other batteries 110, and improve the temperature consistency of the battery device.
[0041] As Figure 4 shown, in an embodiment of the present utility model, the thickness d1 of the heat insulation member 300 can be 0.1 mm to 2 mm, such as 0.1 mm, 0.5 mm, 1 mm, 2 mm, etc. It should be noted that although Figure 4The illustrated embodiment adopts the structural design of "a thermal conductive adhesive layer 400 is provided between the battery 110 and the heat exchange component 200 and the thermal conductive adhesive layer 400 covers the heat insulation member 300", but the identification of the thickness d1 of the heat insulation member 300 is only exemplary. In other words, whether or not there is a thermal conductive adhesive layer 400 between the battery 110 and the heat exchange component 200, or whether or not the thermal conductive adhesive layer 400 covers the heat insulation member 300, the above-mentioned structural design regarding the thickness d1 of the heat insulation member 300 can be adopted in some embodiments of the present invention. Through the above structural design, the present invention can avoid excessive space occupation caused by too large a thickness d1 of the heat insulation member 300, which is beneficial to improving the space utilization rate of the battery device. At the same time, the present invention can avoid the problem that the effect of blocking heat exchange is not obvious due to too small a thickness d2 of the heat insulation member 300. In some embodiments, the thickness d1 of the heat insulation member 300 can also be less than 0.1 mm or greater than 2 mm, such as 0.09 mm, 2.05 mm, etc., and is not limited to this embodiment.
[0042] As Figure 2 shown, in an embodiment of the present invention, the heat insulation member 300 can be a sheet-like structure, and the heat insulation member 300 can be attached to the heat exchange component 200. Through the above structural design, the present invention can further reduce space occupation by using the sheet-like design of the heat insulation member 300, and it is more convenient for industrial implementation by using the attachment method. In some embodiments, for example Figure 5 shown, the heat insulation member 300 having a sheet-like structure can also be attached to the battery 110, and is not limited to this embodiment.
[0043] Refer to Figure 6 and Figure 7 , Figure 6 , a three-dimensional structural schematic diagram of a part of the structure of a battery device that can embody the principle of the present invention in another exemplary embodiment is representatively shown, in which the combined structure of the heat exchange component 200 and the heat insulation member 300 is shown; Figure 7 Representatively shown in Figure 6 is a partial cross-sectional view.
[0044] As Figure 6 and Figure 7 shown, in an embodiment of the present invention, the heat insulation member 300 can be provided with through holes 310. Through the above structural design, the present invention can further balance the heat exchange between the target battery 120 and the heat exchange component 200 by using the through holes 310, avoid the complete blockage of the heat exchange between the target battery 120 and the heat exchange component 200 in the area of the heat insulation member 300, and avoid the problem of uneven heat generation of the target battery 120. It should be noted that Figure 6 and Figure 7Taking the example that the heat insulation member 300 is schematically shown to be arranged on the heat exchange component 200 in the illustrated embodiment, in some embodiments of the present invention, when the heat insulation member 300 is arranged on the side of the battery 110 facing the heat exchange component 200, the heat insulation member 300 may also be provided with through holes 310, and this embodiment is not limiting.
[0045] As Figure 7 shown, based on the structural design in which the heat insulation member 300 is provided with through holes 310, in an embodiment of the present invention, a thermally conductive adhesive layer 400 may be provided in the through holes 310 of the heat insulation member 300. Through the above structural design, the present invention can utilize the thermally conductive adhesive layer 400 to enhance the heat exchange between the target battery 120 and the heat exchange component 200 in the area of the through holes 310, and at the same time can realize the mutual fixation of the target battery 120 and the heat exchange component 200 in these areas via the thermally conductive adhesive layer 400. In some embodiments, when the heat insulation member 300 is provided with through holes 310, other thermally conductive structures made of other materials may also be provided in the through holes 310, such as thermally conductive structures without a cementing effect, or no filling material may be provided in the through holes 310. Additionally, in combination with Figure 4 the illustrated embodiment, the thermally conductive adhesive layer 400 provided in the through holes 310 may be a part of the thermally conductive adhesive layer 400 covering the heat insulation member 300, for example, formed by the thermally conductive adhesive 400 coated on the surface of the heat insulation member 300 flowing into the through holes 310 before solidification. Of course, whether the heat insulation member 300 is covered by the thermally conductive adhesive layer 400 and whether the thermally conductive adhesive layer 400 is provided in the through holes 310 may have no direct relationship, and the two design schemes can be flexibly selected according to needs, and neither is limited to the above embodiment.
[0046] Based on the structural design in which the heat insulation member 300 is provided with through holes 310, in an embodiment of the present invention, the total area of the heat insulation member 300 is defined as S, and the sum of the areas of all the through holes 310 provided in the heat insulation member 300 is defined as S 1 . On this basis, the above total area and the above sum of areas may satisfy the following conditions:
[0047] 4 ≤ S / (S - 0.92·S 1 ) ≤ 6.
[0048] Through the above structural design, since the heat insulation member 300 realizes the heat exchange between the target battery 120 and the heat exchange component 200 at the position where the through holes 310 are provided, that is, at least partially determines the heat exchange effect of the target battery 120, the present invention controls the area of the through holes 310 within a suitable range, which can avoid the heat insulation effect of the heat insulation member 300 from being not obvious enough due to the too large area of the through holes 310, and at the same time can avoid the area of the through holes 310 from being too small and being unfavorable for cooling the target battery 120.
[0049] It should be noted here that the heat exchange devices shown in the drawings and described in this specification are only a few examples of the many heat exchange devices that can employ the principles of the present invention. It should be clearly understood that the principles of the present invention are by no means limited to any details or any components of the heat exchange devices shown in the drawings or described in this specification.
[0050] In summary, the heat exchange device proposed by the present invention is suitable for heat exchange with the battery string 100. The heat exchange device includes a heat exchange component 200 and a heat insulation member 300; the heat exchange component 200 has a first surface 201 facing the battery 110, and the heat exchange component 200 has a cavity inside and is provided with a medium inlet 210; the heat insulation member 300 is at least partially located between the battery 110 and the heat exchange component 200; the battery string 100 includes at least one target battery 120, and the target battery 120 is closer to the medium inlet 210 than the other batteries 110 in the battery string 100. Taking the plane where the first surface 201 is located as the reference plane, on the reference plane, the orthographic projection of the heat insulation member 300 is within the orthographic projection range of the target battery 120 and occupies at least a part of the orthographic projection area of the target battery 120. Through the above structural design, the present invention can use the heat insulation member 300 to block the heat exchange between the heat exchange component 200 in the area and the battery 110, avoiding a large temperature difference between the battery 110 close to the medium inlet 210 and the other batteries 110, which is beneficial to improving the temperature consistency of the battery device.
[0051] Based on the above detailed description of several exemplary embodiments of the heat exchange device proposed by the present invention, the following will describe an exemplary embodiment of the battery device proposed by the present invention.
[0052] As Figure 1 shown, in an embodiment of the present invention, the battery device proposed by the present invention includes a battery string 100 and the heat exchange device proposed by the present invention and described in detail in the above embodiments. The battery string 100 includes at least two batteries 110 arranged along the first direction X, and the heat exchange device is suitable for heat exchange with the battery string 100.
[0053] As Figure 3As shown, in an embodiment of the present utility model, taking the plane where the first surface 201 of the heat exchange component 200 facing the battery 110 is located as the reference plane, on this reference plane, the orthographic projection of the heat insulation member 300 may only occupy a partial area of the orthographic projection of the target battery 120. On this basis, a thermal conductive adhesive layer 400 may be provided between each battery 110 and the heat exchange component 200. That is, for the target battery 120, although the area of the first surface 201 of the heat exchange component 200 corresponding to the target battery 120 is provided with the heat insulation member 300, since the heat insulation member 300 does not completely cover the area of the first surface 201 corresponding to the target battery 120, a thermal conductive adhesive layer 400 may be provided between the non-occupied part of this area by the heat insulation member 300 and the target battery 120. It should be noted that for the convenience of observing the heat insulation member 300, Figure 3 the thermal conductive adhesive layer 400 is hidden. Through the above structural design, the present utility model can use the thermal conductive adhesive layer 400 to fix the battery 110 and the heat exchange component 200, and can achieve heat exchange between the two, thereby further improving the heat exchange effect. In some embodiments, when the orthographic projection of the heat insulation member 300 occupies the entire area of the orthographic projection of the target battery 120, the target battery 120 and the heat exchange component 200 can also be fixedly connected by other means, or indirectly connected through connection with other components, and are not limited to this embodiment.
[0054] As Figure 4 shown, based on the structural design that a thermal conductive adhesive layer 400 is provided between the target battery 120 and the heat exchange component 200, in an embodiment of the present utility model, the thermal conductive adhesive layer 400 may cover the heat insulation member 300. In other words, for the target battery 120, the thermal conductive adhesive layer 400 may not only be provided in the area not occupied by the heat insulation member 300, but also be provided in the area occupied by the heat insulation member 300, and in this area, the thermal conductive adhesive layer 400 is located between the heat insulation member 300 and the battery 110 (or between the heat insulation member 300 and the heat exchange component 200). Accordingly, the thermal conductive adhesive layer 400 in the above two areas can be connected together to achieve the covering of the heat insulation member 300. On this basis, the sum of the thickness d2 of the part of the thermal conductive adhesive layer 400 provided on the heat insulation member 300 and the thickness d1 of the heat insulation member 300 may be equal to the thickness d3 of the part of the thermal conductive adhesive layer 400 not provided with the heat insulation member 300. Through the above structural design, the present utility model can ensure that the thickness of the thermal conductive adhesive layer 400 is uniform at each position, which is beneficial to the grouping of the batteries 110, and at the same time can avoid the excessive thickness of the thermal conductive adhesive layer 400 covering the area of the heat insulation member 300.
[0055] As Figure 4As shown, based on the structural design of the heat-conducting adhesive layer 400 covering the heat-insulating member 300, in an embodiment of the present utility model, the heat-insulating member 300 is disposed on the first surface 201 of the heat-exchanging component 200, and the heat-conducting adhesive layer 400 covers the side and edge of the heat-insulating member 300 facing the battery 110. In other words, the heat-conducting adhesive layer 400 covers all sides of the heat-insulating member 300 except the side facing the heat-exchanging component 200.
[0056] Referring to Figure 5 , Figure 5 FIG. shows a partial cross-sectional view of the heat-exchanging component 200 of the battery device capable of embodying the principle of the present utility model in another exemplary embodiment, and specifically, it can be referred to Figure 4 with respect to Figure 3 the intercepting position.
[0057] Different from Figure 4 the embodiment shown, the structural design of the heat-insulating member 300 disposed on the heat-exchanging component 200 is adopted. As Figure 5 shown, in another embodiment of the present utility model, the heat-insulating member 300 can be disposed on the side of the battery 110 facing the heat-exchanging component 200. At this time, when the heat-conducting adhesive layer 400 covers the heat-insulating member 300, the heat-conducting adhesive layer 400 specifically covers the side and edge of the heat-insulating member 300 facing the heat-exchanging component 200. In other words, the heat-conducting adhesive layer 400 covers all sides of the heat-insulating member 300 except the side facing the target battery 120.
[0058] As Figures 1 to 2 shown, in an embodiment of the present utility model, the battery 110 can be a cylindrical battery 110.
[0059] As Figure 1 and Figure 2 shown, based on the structural design of the battery 110 being a cylindrical battery 110, the cylindrical battery 110 faces the heat-exchanging component 200 with one end face (i.e., the circular surface) thereof. In other words, the end face of the cylindrical battery 110 contacts the heat-exchanging component 200 for heat exchange.
[0060] As Figure 1As shown, in an embodiment of the present invention, the battery device proposed by the present invention includes a battery 110 box body, and the battery 110 box body includes a bottom plate. Among them, the first surface 201 of the heat exchange component 200 can be arranged perpendicular to the bottom plate. In other words, taking the heat exchange component 200 as a heat exchange plate as an example, the heat exchange plate is arranged on the bottom plate in a "vertical" manner. Further, when the battery 110 is a cylindrical battery 110 and the end face of the cylindrical battery 110 contacts the first surface 201 of the heat exchange component 200 for heat exchange, it is equivalent to that the axis of the cylindrical battery 110 is parallel to the bottom plate and perpendicular to the first surface 201 of the heat exchange component 200. Accordingly, the cylindrical battery 110 adopts a "lying" arrangement method.
[0061] As Figure 1 As shown, in an embodiment of the present invention, the battery device proposed by the present invention may include at least two battery columns 100, and these battery columns 100 are arranged along the second direction Y, and the second direction Y is perpendicular to the above-mentioned first direction X. For example, at least one heat exchange component 200 is provided with a battery column 100 on both sides in the second direction Y, that is, at least one heat exchange component 200 simultaneously realizes heat exchange for the two battery columns 100 on both sides. Another example is that at least one heat exchange component 200 is provided with a battery column 100 on only one side in the second direction Y. On this basis, a heat insulation member 300 is provided between the target battery 120 of the battery column 100 located at the end in the second direction Y and the corresponding heat exchange component 200. In other words, a heat insulation member 300 may or may not be provided between the target battery 120 of the battery column 100 located in the middle (except the end) in the second direction Y and the corresponding heat exchange component 200. Through the above structural design, since among the multiple battery columns 100, the temperature of the battery 110 of the battery column 100 located at the end is lower than the temperature of the battery 110 of the battery column 100 located in the middle, the present invention can improve the temperature consistency of the multiple battery columns 100.
[0062] It should be noted here that the battery devices shown in the drawings and described in this specification are only a few examples of many battery devices that can adopt the principles of the present invention. It should be clearly understood that the principles of the present invention are by no means limited to any details or any components of the battery devices shown in the drawings or described in this specification.
[0063] In summary, for the battery device proposed by the present utility model, by adopting the heat exchange device proposed by the present utility model, it is possible to avoid a large temperature difference between the battery 110 (such as the target battery 120) close to the medium inlet 210 and other batteries 110, and has better temperature consistency.

However, the embodiments of the present utility model are not limited to the specific embodiments described herein.
