[0041] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0042] See also Figure 1 In this embodiment, a battery 10 is provided, which is used to store electric energy and can transmit electric energy to connected electric devices. The battery 10 provided in this embodiment can improve the technical problem of poor heat dissipation and cooling effect of the battery 10 in the prior art.

[0043] In this embodiment, please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 The battery 10 includes a fixing bracket 100, a battery cell 200, an air inlet assembly 300, an air outlet assembly 400 and a heating element 500. The fixing bracket 100 includes a plurality of fixing plate structures 101 sequentially spliced ​​along a first direction A, any one of the fixing plate structures 101 has a first mounting surface 102 and a second mounting surface 103 opposite to each other, and a mounting space 104 is formed between the first mounting surface 102 and the second mounting surface 103 on the adjacent fixing plate structure 101; a plurality of convex ribs 110 are arranged at intervals on the first mounting surface 102 along the second direction B. The battery cell 200 is arranged in the mounting space 104, and one of the side surfaces of the battery cell 200 along the first direction A abuts against the convex rib 110, so that a plurality of cooling channels 111 arranged at intervals are formed between adjacent convex ribs 110 along the second direction B. The other side surface of the battery cell 200 along the first direction A abuts against the second mounting surface 103. The air inlet assembly 300 is disposed at the bottom of the plurality of battery cells 200, and an air inlet channel 310 is disposed inside the air inlet assembly 300 and is connected to the plurality of cooling channels 111. The air outlet assembly 400 is disposed at the top of the plurality of battery cells 200, and an air outlet channel 410 is disposed inside the air outlet assembly 400 and is connected to the plurality of cooling channels 111. The heating element 500 is disposed on both sides of the plurality of battery cells 200 along the second direction B, and is used to heat the battery cells 200.

[0044] In the battery 10, the battery cell 200 is arranged between two adjacent fixing brackets 100, and a cooling channel 111 adjacent to the battery cell 200 is formed by a plurality of convex ribs 110 on the first mounting surface 102 of the fixing bracket 100; since the battery cell 200 is directly against the convex ribs 110, the airflow in the cooling channel 111 can directly contact the battery cell 200. When the air inlet channel 310 is inlet, the airflow enters the cooling channel 111 and directly contacts the battery cell 200 for heat exchange, which can provide heat dissipation and cooling for the battery cell 200; after the airflow flows through the cooling channel 111, it is guided out by the air outlet channel 410. Since a plurality of convex ribs 110 are arranged on the first mounting surface 102, a plurality of cooling channels 111 are formed, and a cooling effect is provided to the battery cell 200 through the plurality of cooling channels 111, which can directly provide efficient cooling and temperature reduction for the battery cell 200, thereby achieving the purpose of improving the problem of poor cooling and heat dissipation effect of the battery 10 in the prior art. Since the convex rib 110 is against the side surface of the battery cell 200 along the thickness direction, that is, the large surface of the battery cell 200, heat dissipation and cooling can be provided to the battery cell 200 from the large surface of the battery cell 200, which is beneficial for the battery cell 200 to quickly complete heat dissipation and cooling, and improve the heat dissipation effect.

[0045] In addition, if the battery 10 is operating in a low temperature environment, the heating element 500 can be used to heat the battery cell 200, thereby ensuring that the temperature of the environment in which the battery cell 200 is located is maintained in a suitable temperature range to ensure that the battery cell 200 operates stably, which can ensure the stable operation of the battery 10.

[0046] It is worth noting that when the battery 10 is used in a device that is in a moving state during operation, such as an aircraft, the airflow formed during the movement can be used to introduce airflow into the air inlet channel 310, so that the cooling airflow can be continuously introduced into the cooling channel 111 when the battery cell 200 is in operation, thereby improving the cooling effect of the battery cell 200. Of course, in order to facilitate the introduction of airflow into the air inlet channel 310 by equipment such as aircraft during movement, the air inlet of the air inlet channel 310 can be set on the windward side of the equipment, that is, in front of the direction of movement of the equipment, which is conducive to the airflow entering the air inlet channel 310 from the air inlet, thereby improving the cooling effect on the battery cell 200.

[0047] In addition, the convex ribs 110 provided on the first mounting surface 102 of the fixed plate structure 101 can also provide reinforcement for the fixed plate structure 101, thereby improving the overall strength of the fixed plate structure 101, thereby improving the overall strength of the fixed bracket 100, ensuring that the multiple battery cells 200 are stably supported and loaded, and thus improving the overall stability of the battery cells 200. Further, in this embodiment, the convex ribs 110 extend on the first mounting surface 102 in a direction perpendicular to the second direction B to form a strip structure. In other words, the convex ribs 110 are in a vertically arranged state. Based on this, a vertical cooling channel 111 is formed between two adjacent convex ribs 110, and the cooling channel 111 extends from the top of the battery cell 200 to the bottom of the battery cell 200.

[0048] Optionally, in this embodiment, the fixed plate structure 101 includes a plate body 120 and two first splicing pieces 130; the first mounting surface 102 and the second mounting surface 103 are arranged on both sides of the thickness direction of the plate body 120; the two first splicing pieces 130 are arranged at intervals on the top of the plate body 120, and the two first splicing pieces 130 are used to respectively splice with the two first splicing pieces 130 on the adjacent fixed plate structure 101; the air outlet assembly 400 is sealed and connected to the first splicing piece 130, and the air outlet channel 410 is connected to the cooling channel 111 through the gap between the two first splicing pieces 130.

[0049] When the plurality of fixed plate structures 101 are spliced, the plurality of first splicing pieces 130 are spliced ​​to form two rows of spaced-apart long strip structures, and the long strip structures are extended along the first direction A. A gap connected to the cooling channel 111 is formed between the two long strip structures, and the gap is also connected to the air outlet channel 410. The airflows derived from the plurality of cooling channels 111 can be gathered in the gap, and then the airflows are derived from the air outlet channel 410.

[0050] Among them, two adjacent fixed plate structures 101 are spliced ​​together by two first splicing pieces 130, which can facilitate the stable connection of the two adjacent fixed plate structures 101 on the one hand; on the other hand, the two fixed plate structures 101 can also be positioned by the first splicing pieces 130 to prevent the fixed plate structures 101 from shifting in the second direction B and causing the two fixed plate structures 101 to be misaligned. In addition, when assembling two adjacent fixed plate structures 101, the splicing of the two first splicing pieces 130 can also improve assembly accuracy and assembly efficiency.

[0051] In addition, in the present embodiment, the air outlet assembly 400 includes a first main body and an air outlet piece. The interior of the first main body is provided with an air outlet channel 410 for air flow to pass through, and the first main body is provided with an opening connected to the air outlet channel 410 on a side close to the first splicing piece 130. The cross section of the portion of the first main body corresponding to the opening in the vertical direction is U-shaped, and it can also be regarded that the opening corresponds to the multiple cooling channels 111 between the multiple battery cells 200, so as to facilitate the collection and export of airflow. In addition, a blocking structure is provided at both ends of the first main body, and the two ends of the long strip structure formed after the multiple first splicing pieces 130 are completed are respectively abutted against the blocking structures at both ends of the first main body, which is conducive to the export of airflow along the air outlet channel 410 and facilitates the smooth flow of airflow. The air outlet piece is provided on the outside of one of the blocking structures, and a channel connected to the air outlet channel 410 is formed on the air outlet piece, and the outlet of the channel forms an air outlet.

[0052] The air outlet assembly 400 and the first assembling piece 130 are sealed together, which means that a second sealing member 420 is provided between the long strip structure formed by the first body and the first assembling piece 130, and the second sealing member 420 is provided at the opening of the first body to seal the gap between the first body and the first assembling piece 130. It should be understood that in other embodiments, the air outlet assembly 400 and the first assembling piece 130 are sealed together, which may refer to other methods, for example, by applying a sealing coating to the gap between the first body and the first assembling piece 130 to achieve sealing; for another example, a groove may be provided on the first assembling piece 130, and the first body may be embedded in the groove to form a seal.

[0053] In addition, in order to improve the assembly stability of the air outlet component 400 and the first splicing piece 130, the two ends of the long strip structure formed by the first splicing piece 130 are respectively matched with the blocking structures at the two ends of the first main body. For example, the first splicing piece 130 can be abutted and matched with the side of the blocking structure close to the air outlet channel 410; for another example, a through hole can be opened in the blocking structure, and correspondingly, the first splicing piece 130 has a structure that is plugged into the through hole, thereby realizing the plug-in cooperation between the first splicing piece 130 and the blocking structure.

[0054] Optionally, in this embodiment, please refer to Figure 5 , Figure 6 and Figure 7The first splicing piece 130 includes a first plug-in portion 131 and a first matching portion 132 connected to the first plug-in portion 131. The first matching portion 132 is connected to the board body 120. A first slot 1321 for use with the first plug-in portion 131 is provided at one end of the first matching portion 132 away from the first plug-in portion 131. The first plug-in portion 131 is inserted into the first slot 1321 of the adjacent fixed plate structure 101, and the two first matching portions 132 are abutted against each other. The first matching portion 132 and the first plug-in portion 131 are extended along the first direction A. When assembling multiple fixed plate structures 101, the first plug-in portion 131 on the first splicing piece 130 is sequentially plugged into the first matching portion 132 on another adjacent first splicing piece 130, so that multiple first splicing pieces 130 can be spliced ​​in sequence, and multiple fixed plate structures 101 can be spliced ​​along the first direction A at the same time.

[0055] It should be understood that in other embodiments of the present application, the first assembling pieces 130 may be assembled in other ways, for example, a plurality of first assembling pieces 130 may be assembled in sequence by bonding.

[0056] Furthermore, in this embodiment, the cross-sectional area of ​​the first connector gradually decreases from one end close to the first mating portion 132 to one end away from the first mating portion 132. Correspondingly, the first slot 1321 on the first mating portion 132 is flared, thereby facilitating the insertion of the first connector into the first mating portion 132 and improving assembly efficiency.

[0057] Optionally, in this embodiment, the fixed plate structure 101 further includes a first closing member 140, which is disposed on a side of the plate body 120 close to the first mounting surface 102, and the first closing member 140 covers the gap outside the two first splicing members 130. A plurality of convex ribs 110 are disposed on the first mounting surface 102, and the area where the convex ribs 110 are arranged partially corresponds to the area outside the two first splicing members 130. In order to facilitate the cooling channel 111 corresponding to the area outside the two first splicing members 130 to guide the airflow to the air outlet channel 410, the first closing member 140 is disposed on the plate body 120 to block the cooling channel 111 corresponding to the area outside the two first splicing members 130. Of course, in order to facilitate the cooling channel 111 corresponding to the external area of ​​the two first splicing parts 130 to guide the airflow to the air outlet channel 410, the end of the rib 110 is spaced from the first closing part 140, thereby preventing the first closing part 140 from completely closing the cooling channel 111, making it convenient for the airflow to flow through the cooling channel 111 to dissipate heat and cool the battery cell 200.

[0058] It is worth noting that when the battery cells 200 are arranged between the fixed plate structures 101 , the first sealing member 140 is arranged in contact with the poles of the battery cells 200 to conveniently shield the cooling channels 111 corresponding to the outer areas of the two first assembling members 130 .

[0059] Furthermore, the fixed plate structure 101 further includes a second closing member 150, which is disposed on the side of the plate body 120 close to the second mounting surface 103, and the second closing member 150 is spaced apart from the first mounting surface 102 in the adjacent fixed plate structure 101. When the fixed plate structure 101 and the battery cell 200 are assembled, the second closing member 150 contacts the top surface of the battery cell 200, and the second closing member 150 has a notch corresponding to the explosion-proof valve. The provision of the second closing member 150 can provide a limiting effect on the battery cell 200, ensuring the stability of the battery cell 200; on the other hand, the first closing member 140 can also transfer the temperature of the top surface of the battery cell 200 to the plate body 120, thereby achieving heat dissipation and cooling of the top surface of the battery cell 200, and improving the heat dissipation efficiency of the battery cell 200. In addition, spacing the second closing member 150 from the first mounting surface 102 in the adjacent fixed plate structure 101 can prevent the second closing member 150 from blocking the cooling channel 111 corresponding to the area between the two first splicing members 130 , thereby preventing the airflow in the cooling channel 111 from being affected.

[0060] In this example, please continue to refer to Figure 3 , Figure 4 and Figure 5 The fixed plate structure 101 further includes a splicing assembly 160, which is disposed on a side of the plate body 120 away from the first splicing piece 130. The splicing assembly 160 is spliced ​​with the splicing assembly 160 of the adjacent fixed plate structure 101 to form a gap connected to the cooling channel 111; the air inlet channel 310 is connected to the cooling channel 111 through the gap. When the air inlet channel 310 is fed with air, the airflow in the air inlet channel 310 is introduced from the gap between the splicing assembly 160 and another fixed plate structure 101 to the multiple cooling channels 111, so as to achieve heat dissipation and cooling of the battery cell 200.

[0061] Among them, one side of the board body 120 is spliced ​​by multiple first splicing pieces 130, and the other side is spliced ​​by splicing a splicing assembly 160, which can provide a connection function to the board body 120 from both sides, which is beneficial to improve the assembly stability of multiple fixed board structures 101, and then improve the assembly stability of the battery cell 200.

[0062] In this embodiment, the splicing assembly 160 includes a third closing piece 162 and two second splicing pieces 161. The third closing piece 162 is arranged at the bottom of the plate body 120, and the two second splicing pieces 161 are arranged at intervals at the bottom of the third closing piece 162; the two second splicing pieces 161 are respectively spliced ​​with the two second splicing pieces 161 in another fixed plate structure 101, and the third closing piece 162 is spliced ​​with the third closing piece 162 in another fixed plate structure 101, and a gap connecting the cooling channel 111 is formed between the two second splicing pieces 161, and the air inlet channel 310 is connected to the cooling channel 111 through the gap; the air inlet assembly 300 is connected and sealed to the two second splicing pieces 161.

[0063] It is worth noting that in this embodiment, the third sealing member 162 is divided into two parts. One part corresponds to the position between the two second splicing members 161. After the two fixed plate structures 101 are spliced, a gap is formed between the third sealing members 162 of this part. In addition, after the two fixed plate structures 101 are spliced, the third sealing members 162 of the other part contact each other to block the cooling channel 111 corresponding to the area, preventing the airflow of the cooling channel 111 in the area from leaking out; and the second splicing member 161 is arranged on the third sealing member 162 of this part.

[0064] In this embodiment, the second splicing piece 161 includes a second plug-in portion 1611 and a second matching portion 1612 connected to the second plug-in portion 1611, the second matching portion 1612 is connected to the board body 120, and a second slot 1613 for use with the second plug-in portion 1611 is provided at one end of the second matching portion 1612 away from the second plug-in portion 1611; the second plug-in portion 1611 is inserted into the second slot 1613 of the adjacent fixed plate structure 101, and the two second matching portions 1612 are abutted against each other. In other words, the structure of the second splicing piece 161 is similar to that of the first splicing piece 130, and will not be described in detail here.

[0065] In addition, in this embodiment, a connecting portion 430 is provided at the end of the air inlet assembly 300. Fig. 9 , a third slot 431 is provided on the connecting portion 430, and the second splicing piece 161 is inserted into the third slot 431. The air inlet assembly 300 can also be divided into a second body and an air inlet piece. The structure of the second body is similar to that of the first body, and will not be repeated here. The connecting portion 430 is a blocking structure located at the end of the second body. The air inlet piece is arranged on one of the blocking structures, and forms a channel connected to the air inlet channel 310, and the entrance of the channel is the air inlet.

[0066] It should be noted that the air inlet assembly 300 is connected and sealed with the two second assembling pieces 161, which means that a first sealing piece 320 is provided between the second body and the second assembling piece 161, and the gap between the second body and the second assembling piece 161 is sealed by the first sealing piece 320. The first sealing piece 320 is provided in the air inlet channel 310 and is located on both sides of the second direction B, and the second assembling piece 161 abuts against the first sealing piece 320 to achieve sealing.

[0067] In this embodiment, the air inlet member and the air outlet member are arranged at two different ends in the first direction A, thereby forming a diagonal arrangement, such as Figure 8 , which is beneficial to ensure uniform air volume, improve the average temperature of the battery cell 200 and the service life of the entire battery 10.

[0068] Based on the battery 10 provided above, this embodiment further provides an electric device (not shown), which adopts the battery 10 and can improve the technical problem of poor heat dissipation and cooling effect of the battery in the prior art.

[0069] In summary, in the battery 10, the battery cell 200 is arranged between two adjacent fixing brackets 100, and a cooling channel 111 adjacent to the battery cell 200 is formed by a plurality of convex ribs 110 on the first mounting surface 102 of the fixing bracket 100; since the battery cell 200 is directly against the convex ribs 110, the airflow in the cooling channel 111 can directly contact the battery cell 200. When the air inlet channel 310 is inlet, the airflow enters the cooling channel 111 and directly contacts the battery cell 200 for heat exchange, which can provide heat dissipation and cooling for the battery cell 200; after the airflow flows through the cooling channel 111, it is guided out by the air outlet channel 410. Among them, since a plurality of convex ribs 110 are arranged on the first mounting surface 102, a plurality of cooling channels 111 are formed, and a cooling effect is provided to the battery cell 200 through the plurality of cooling channels 111, which can directly provide efficient cooling and temperature reduction for the battery cell 200, thereby achieving the purpose of improving the problem of poor cooling and heat dissipation effect of the battery 10 in the prior art. In addition, if the battery 10 is operating in a low temperature environment, the heating element 500 can be used to provide heating to the battery cell 200, thereby ensuring that the temperature of the environment in which the battery cell 200 is located is maintained in a suitable temperature range, so as to ensure the stable operation of the battery cell 200, and the stable operation of the battery 10 can be ensured. It is worth noting that when the battery 10 is applied to equipment that is in a moving state, such as an aircraft, the airflow formed during the moving process can be used to introduce airflow into the air inlet channel 310, and the cooling airflow can be continuously introduced into the cooling channel 111 when the battery cell 200 is in a running state, thereby improving the cooling effect of the battery cell 200.

[0070] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
