For example, the battery referred to in the present application may include a battery module or a battery pack, or the like. The battery generally includes a case for enclosing one or more battery cells. The case body can prevent liquid or other foreign matters from affecting the charge or discharge of the battery cells.
The battery cell comprises an electrode assembly and electrolyte, wherein the electrode assembly consists of a cathode pole piece, an anode pole piece and a separation film. The battery cell mainly relies on metal ions to move between the cathode and anode electrode sheets. During the charge and discharge of the battery cell, active ions (e.g., lithium ions) are inserted and extracted back and forth between the positive electrode and the negative electrode.

The thermal management components within the battery typically include water inlets and water outlets, and the water outlets and water inlets of the plurality of thermal management components may be connected to one another by piping to allow communication between the plurality of thermal management components. When the water inlet and the water outlet of the heat management component are connected with the pipeline, the pipeline is usually inserted into the water inlet or the water outlet in an interference fit mode. Because the structural strength of the thermal management component is limited, if the insertion force is large, the structures at the water inlet and the water outlet are easily damaged, for example, the water inlet and the water outlet are easily recessed, the qualification rate of battery processing and assembly is lower, and the reliability and the structural stability of the battery are also affected.
Accordingly, embodiments of the present application provide a thermal management component, a battery, and an electrical device, which can solve the above-mentioned problems. The heat management component of the embodiment of the application comprises a first connecting pipe and a second connecting pipe which are communicated, and a reinforcing pipe, wherein the reinforcing pipe is positioned inside the first connecting pipe and the second connecting pipe and is connected with the first connecting pipe and the second connecting pipe. The side wall of the reinforcing pipe is provided with at least one opening, so that fluid flowing in from the first connection pipe can enter the thermal management component through the at least one opening of the reinforcing pipe and can flow out of the thermal management component through the second connection pipe. Because the first connecting pipe and the second connecting pipe are internally provided with the reinforcing pipe, the reinforcing pipe is provided with at least one opening, fluid can flow into the thermal management component through the at least one opening, and the reinforcing pipe can increase the structural strength of the thermal management component at the first connecting pipe and the second connecting pipe, so that the structural stability and the reliability of the thermal management component are improved.
The technical scheme described in the embodiment of the application is applicable to various electric equipment using batteries.
The electric equipment can be vehicles, mobile phones, portable equipment, notebook computers, ships, spacecrafts, electric toys, electric tools and the like.

Fig. 4 shows a partially schematic exploded structure of the thermal management component 13 of an embodiment of the present application, for example, the thermal management component 13 shown in fig. 4 may be a partially schematic view of the thermal management component 13 shown in fig. 3. Fig. 5 illustrates a schematic cross-sectional view of a thermal management component 13 according to an embodiment of the present application, and the thermal management component 13 illustrated in fig. 5 may be a cross-sectional view of the thermal management component 13 illustrated in fig. 3, which is perpendicular to the length direction Y of the thermal management component 13 through a first connection pipe 131 and a second connection pipe 132 of the thermal management component 13.
As shown in fig. 3 to 5, the thermal management component 13 of the embodiment of the present application includes: a first connection pipe 131 and a second connection pipe 132 which are communicated; a reinforcing pipe 133, the reinforcing pipe 133 being located inside the first and second connection pipes 131 and 132 and connecting the first and second connection pipes 131 and 132, a sidewall of the reinforcing pipe 133 being provided with at least one opening 134, and fluid flowing in from the first connection pipe 131 being used to enter the thermal management part 13 through the at least one opening 134 and to flow out of the thermal management part 13 through the second connection pipe 132.
It should be understood that the communication of the first connection tube 131 with the second connection tube 132 of the present embodiment means that fluid may flow between the first connection tube 131 and the second connection tube 132. Specifically, fluid may enter the thermal management component 13 from the first connection tube 131, and then flow out of the thermal management component 13 from the second connection tube 132. In addition, if the battery 10 includes a plurality of thermal management components 13, for two adjacent thermal management components 13, the first connection pipe 131 of one thermal management component 13 is communicated with the second connection pipe 132 of the other thermal management component 13, so that, for any thermal management component 13, after flowing in from the first connection pipe 131, the fluid flows out from the second connection pipe 132, and then the fluid continues to flow in from the first connection pipe 131 of the next adjacent thermal management component 13 and flows out from the second connection pipe 132 of the thermal management component 13, so that the plurality of thermal management components 13 included in the battery 10 are communicated with each other, thereby improving the efficiency of temperature adjustment of the thermal management components 13.
The reinforcing pipe 133 of the embodiment of the present application is disposed inside the first and second connection pipes 131 and 132, and the reinforcing pipe 133 may be used to connect the first and second connection pipes 131 and 132; in addition, since the reinforcing pipe 133 is provided with at least one opening 134, the fluid entering through the first connecting pipe 131 may flow into the thermal management component 13 through the at least one opening 134, and the fluid may also flow out of the thermal management component 13 through the second connecting pipe 132.
Therefore, in the thermal management component 13 of the embodiment of the present application, since the first connection pipe 131 and the second connection pipe 132 are internally provided with the reinforcing pipe 133, the reinforcing pipe 133 is provided with at least one opening 134, and the fluid can flow into the thermal management component 13 through the at least one opening 134, the reinforcing pipe 133 can increase the structural strength of the thermal management component 13 at the first connection pipe 131 and the second connection pipe 132, thereby improving the structural stability and reliability of the thermal management component 13.
It should be appreciated that the size and shape of the stiffening tube 133 of the present embodiments may be flexibly configured depending on the application. For example, the reinforcing tube 133 may be a round tube, or a square tube, for easy processing. For convenience of description, the reinforcing pipe 133 is mainly used as a circular pipe in the embodiment of the present application, but the embodiment of the present application is not limited thereto.
The wall thickness H of the reinforcing tube 133 of the present embodiment may be set according to practical applications to satisfy design requirements. Specifically, the wall thickness H of the reinforcing tube 133 is not too large, and if too large, the inner diameter of the reinforcing tube 133 may be too small, which is not beneficial for the fluid to flow through the reinforcing tube 133 rapidly, or the outer diameter of the reinforcing tube 133 may be too large, which is not beneficial for the space utilization of the battery 10. Conversely, the wall thickness H of the reinforcing tube 133 is not too small, and if too small, the processing difficulty is increased, the structural strength of the reinforcing tube 133 is reduced, the reinforcing effect of the reinforcing tube 133 is weakened, and the structural strength of the thermal management component 13 is not good.
Therefore, the wall thickness H of the reinforcing tube 133 of the embodiment of the present application is not preferably set too large or too small. For example, the wall thickness H of the reinforcing tube 133 may be set to a value in the range of 0.2mm,3mm, and further, for example, 0.8mm,1.2mm, so that the thickness of the reinforcing tube 133 satisfies both strength requirements and is easy to process. In particular, the wall thickness H of the reinforcing tube 133 may be specifically set to 0.2mm, 0.5mm, 0.8mm, 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, 2.2mm, 2.5mm, 2.8mm or 3mm.
The reinforcing pipe 133 of the embodiment of the present application is provided with at least one opening 134, and the number of the at least one opening 134 may be set according to practical applications. For example, the number of openings 134 may be appropriately selected according to the size of the reinforcing tube 133 to facilitate processing.
In some embodiments, if the reinforcing tube 133 is provided with a plurality of openings 134, the plurality of openings 134 may be the same or different in shape, and the plurality of openings 134 may be the same or different in size. For example, a plurality of openings 134 having the same shape may be provided for processing, for example, the shape of the opening 134 may be rectangular, circular, elliptical, or the like. For another example, the plurality of openings 134 may be equally sized for ease of machining and installation.
For another example, the side wall of the reinforcing pipe 133 is provided with a plurality of openings 134, and the plurality of openings 134 are different in size along the circumferential direction W of the reinforcing pipe 133. The fluid flows into the thermal management component 13 through the openings 134 of the reinforcing pipe 133, and the plurality of openings 134 are provided along the circumferential direction W of the reinforcing pipe 133 with different sizes, so that the speed and the flow rate of the fluid entering the thermal management component 13 can be adjusted according to actual requirements, and the processing efficiency of the thermal management component 13 can be improved.
It should be appreciated that the opening 134 of the stiffening tube 133 of the present embodiments may be implemented in a variety of ways. For example, the sidewall of the reinforcing tube 133 may be hollow, and the hollow area is at least one opening 134. As another example, as shown in fig. 3 to 5, an opening 134 may be provided at one end of the reinforcing tube 133 to facilitate processing. In particular, fig. 6 illustrates a side view of a stiffening tube 133 of an embodiment of the present application, for example, the stiffening tube 133 illustrated in fig. 6 may be a side view of the stiffening tube 133 comprised by the thermal management component 13 as illustrated in fig. 3-5. As shown in fig. 3 to 6, along the extending direction X of the reinforcing pipe 133, the reinforcing pipe 133 includes a main body section 1331 and an extending section 1332 connected to each other, at least one opening 134 is located at the extending section 1332, and each opening 134 of the at least one opening 134 penetrates the extending section 1332 along the extending direction X of the reinforcing pipe 133. In this way, the at least one opening 134 is relatively fixed at the distribution position of the reinforcing pipe 133, and the extending direction of each opening 134 is uniform, i.e., each opening 134 extends along the extending direction X of the reinforcing pipe 133, thereby facilitating processing and installation.
In some embodiments, if the reinforcing tube 133 includes a plurality of openings 134, the plurality of openings 134 may have the same or different dimensions along the extending direction X of the reinforcing tube 133. For example, as shown in fig. 6, the plurality of openings 134 may be equal in size to L along the extending direction X of the reinforcing pipe 133 for easy processing.
In the embodiment of the present application, the position of the reinforcing tube 133 may also be set according to practical applications. For example, the main body section 1331 is adjacent to the first connecting tube 131 and the extension section 1332 is adjacent to the second connecting tube 132. Considering that the fluid enters the reinforcing pipe 133 and the thermal management member 13 from the first connection pipe 131 and flows out from the second connection pipe 132, the force applied to the reinforcing pipe 133 when the fluid flows in may be slightly greater than the force applied to the reinforcing pipe 133 when the fluid flows out. The main section 1331 excluding the opening 134 has a greater structural strength than the extension section 1332 including the opening 134, so that the main section 1331 is disposed close to the first connection tube 131, which may improve the stability of the reinforcing tube 133 and thus the structural stability of the thermal management component 13.
It should be appreciated that the reinforcing tube 133 of the present embodiment may be fixed between the first and second connection tubes 131 and 132 in various manners. For example, as shown in fig. 3 to 6, the inner wall of the first connection pipe 131 is provided with a first limit structure 1313, the inner wall of the second connection pipe 132 is provided with a second limit structure 1323, and the reinforcement pipe 133 is located between the first limit structure 1313 and the second limit structure 1323. The first limit structure 1313 and the second limit structure 1323 limit the position of the reinforcing pipe 133 together, so that the misalignment between the reinforcing pipe 133 and the first connecting pipe 131 can be reduced, the misalignment between the reinforcing pipe 133 and the second connecting pipe 132 can be reduced, and the structural stability can be improved.
The first stop structure 1313 and the second stop structure 1323 of the embodiments of the present application may be implemented in a variety of ways. For example, as shown in fig. 3 to 6, the first limiting structure 1313 includes a stepped structure provided to an inner wall of the first connection pipe 131; and/or, the second limiting structure 1323 includes a step structure disposed on an inner wall of the second connecting pipe 132, and then two ends of the reinforcing pipe 133 may be disposed between the step structure of the first limiting structure 1313 and the step structure of the second limiting structure 1323, respectively, so that the structure is simple and easy to implement.
In some embodiments, the first connection pipe 131 side wall may have a continuous stepped structure disposed around the circumference W of the first connection pipe 131, or the first connection pipe 131 side wall may also have a plurality of stepped structures spaced around the circumference W of the first connection pipe 131. Similarly, the second connection pipe 132 side wall may have a continuous stepped structure disposed around the circumferential direction W of the second connection pipe 132, or the second connection pipe 132 side wall may have a plurality of stepped structures disposed at intervals around the circumferential direction W of the second connection pipe 132.
It should be appreciated that the thermal management component 13 of the present embodiment includes a first plate 135 and a second plate 136, the first plate 135 having a raised region 1351 and the second plate 136 having a first recessed region 1361, the raised region 1351 being disposed opposite the first recessed region 1361 to form a flow channel 138, the flow channel 138 for receiving a fluid that can be used to regulate the temperature of the battery cell 20, and is simple in construction and easy to implement.
Specifically, fig. 7 shows a schematic partial structure of the second plate 136 according to an embodiment of the present application, and for example, the second plate 136 shown in fig. 7 may be the second plate 136 included in the thermal management component 13 shown in fig. 3 to 5. As shown in fig. 3-7, the second plate 136 of the present embodiment has a first recessed region 1361, and a hollow flow channel 138 may be formed by disposing the first recessed region 1361 opposite at least a portion of the raised region 1351 of the first plate 135, and the flow channel 138 may be used to contain a fluid.
In some embodiments, as shown in fig. 3-7, the raised area 1351 of the first plate 135 may be a continuous large area for ease of processing; the second plate 136 may be disposed in the same or different manner as the first plate 135. For example, as shown in fig. 3 to 7, the second plate 136 may be disposed differently from the first plate 135, and the first concave region 1361 of the second plate 136 may not completely correspond to the convex region 1351, for example, the second plate 136 may further have a protrusion 1364 adjacent to the first concave region 1361, and the protrusion 1364 of the second plate 136 is disposed opposite to a partial region of the convex region 1351 of the first plate 135 and is accommodated in the convex region 1351 of the first plate 135, and the partial region cannot accommodate fluid, so as to reduce the proportion of the flow channel 138 to the thermal management component 13, reduce the weight of the thermal management component 13, and further reduce the weight of the entire battery 10.
In some embodiments, the thermal management component 13 further includes a third plate 137, the second plate 136 being positioned between the first plate 135 and the third plate 137, the third plate 137 having a second recessed region 1371, the second recessed region 1371 for receiving the first recessed region 1361. The third plate 137 may be disposed opposite to the first plate 135, that is, the second concave region 1371 is disposed opposite to the convex region 1351 such that the second plate 136 is located in the middle, and thus, a surface of the second concave region 1371, which is far from the first plate 135, may be disposed flat, and likewise, a surface of the convex region 1351, which is far from the third plate 137, may be disposed flat, so that the thermal management member 13 may improve the stability of the overall structure and facilitate the installation of the battery 10 when being clamped between the plurality of battery cells 20.
It should be understood that the first plate 135 and the third plate 137 may be disposed in a similar manner in the embodiment of the present application, and the description below will mainly be given by way of example of the first plate 135, but the description applies to the third plate 137.
Fig. 8 shows a partially exploded schematic view of the first plate 135, the first connection pipe 131, and the reinforcement pipe 133 according to the embodiment of the present application, for example, the first plate 135, the first connection pipe 131, and the reinforcement pipe 133 shown in fig. 8 may correspond to the first plate 135, the first connection pipe 131, and the reinforcement pipe 133 shown in fig. 3 to 7, respectively.
In the present embodiment, the raised area 1351 is provided with a first hole 1352, and the first connecting tube 131 is connected to the flow channel 138 through the first hole 1352, and the reinforcing tube 133 penetrates the first hole 1352. As shown in fig. 8, the raised area 1351 may be used to form the flow channel 138, and the first hole 1352 is disposed in the raised area 1351, so that the first connection pipe 131 is connected to the first hole 1352, and may be connected to the flow channel 138 through the first hole 1352; in addition, the reinforcing pipe 133 penetrates the first hole 1352, and the reinforcing pipe 133 may be connected to the flow channel 138 through the first hole 1352. In this way, fluid enters the stiffening tube 133 through the first connecting tube 131 and the first hole 1352 and may pass through the stiffening tube 133 into the flow channel 138 at the raised area 1351 for being received in the thermal management device 13.
Similar to the first plate 135, the third plate 137 is provided with a third hole 1372, and the second connection pipe 132 is connected to the flow channel 138 through the third hole 1372, and the reinforcement pipe 133 penetrates the third hole 1372. Specifically, the third plate 137 may be provided with a third hole 1372, and the second connection pipe 132 is connected to the third hole 1372, and thus may be connected to the flow channel 138 through the third hole 1372. In this way, the fluid in the flow channel 138 can flow out of the thermal management component 13 through the third hole 1372 and the second connection tube 132, which is simple in structure and easy to implement. In some embodiments, the third hole 1372 may be provided in the second recess region 1371 of the third plate 137, but the embodiment is not limited thereto.
In the present embodiment, the first hole 1352 is provided with a shielding region 1353, and the shielding region 1353 is accommodated in the first opening 1341 of the at least one opening 134. In particular, the shielding region 1353 of the first hole 1352 may be a local irregular region of the first hole 1352. Taking the example of a symmetrical pattern when the first hole 1352 does not include the shielding area 1353, the shielding area 1353 may be configured such that the first hole 1352 becomes an asymmetrical pattern. For example, as shown in fig. 3 to 8, taking the first hole 1352 as an example of a circular hole, the shielding area 1353 may be implemented by setting a local area of the circular hole to be a linear type, which is not limited thereto.
The shielding region 1353 can be received in the first opening 1341, the first opening 1341 can be any one of the openings 134 of the stiffening tube 133, and the shielding region 1353 can be used to limit movement of the stiffening tube 133 within the first hole 1352, thereby enabling positioning and mounting of the stiffening tube 133. For example, the shielding region 1353 may limit the amount of angle by which the stiffening tube 133 rotates within the first bore 1352 along the circumferential direction W of the stiffening tube 133, and for example, the shielding region 1353 may also limit the amount of length of the stiffening tube 133 that moves within the first bore 1352 along the length direction X of the stiffening tube 133.
It should be appreciated that considering that the battery 10 may include multiple thermal management components, the relative positions of the shielding regions 1353 of different thermal management components 13 may be the same or different. For example, the location of the shielding region 1353 of the plurality of thermal management members 13 relative to the first aperture 1352 may be provided differently so as to distinguish between the different locations of the thermal management members 13 by the relative location of the shielding region 1353. For example, the shielding regions 1353 of different thermal management members 13 may be rotatably disposed along the circumferential direction W of the first aperture 1352.
In the present embodiment, the third plate 137 may be provided with a shielding region to restrict movement between the reinforcing tube 133 and the third hole 1372, similar to the first plate 135; alternatively, the third plate 137 may not be provided with a shielding region to facilitate installation.
It should be appreciated that the first connection pipe 131 of the present embodiment may be connected to the first hole 1352 in various manners; the second connection tube 132 may be connected to the second hole 1362 in various manners; the connection between the first connection pipe 131 and the first hole 1352 and the connection between the second connection pipe 132 and the second hole 1362 may be the same or different.
Fig. 9 illustrates a schematic structural view of another angle of the first connection pipe 131 according to the embodiment of the present application, for example, the first connection pipe 131 illustrated in fig. 9 may be a schematic structural view of another angle of the first connection pipe 131 illustrated in fig. 8.
In some embodiments, the first connection tube 131 includes a first connection segment 1311, the first connection segment 1311 being received within the first bore 1352. As shown in fig. 3 to 9, since the first plate 135 has a certain thickness, the first connection section 1311 of the first connection pipe 131 is received in the first hole 1352, the area of the contact area between the first connection pipe 131 and the first hole 1352 can be increased, and thus the connection strength between the first connection pipe 131 and the first hole 1352 can be improved. For example, the fixed connection between the first connection pipe 131 and the first hole 1352 may be achieved by welding, and then the first connection section 1311 is accommodated in the first hole 1352, so that the area of the weldable region between the first connection pipe 131 and the first hole 1352 may be increased, thereby improving welding strength and welding efficiency.
Similarly, the second connection tube 132 may include a second connection section 1321, the second connection section 1321 being received in the third hole 1372 to enhance the connection strength between the second connection tube 132 and the third hole 1372.
In some embodiments, first connecting section 1311 includes a relief opening 1312, with relief opening 1312 serving to clear an occlusion region 1353. Since the first hole 1352 may be provided with a shielding area 1353, the shielding area 1353 may obstruct the first connection section 1311, and thus, the shielding area 1353 may be avoided by providing the avoidance opening 1312, so that an area of the first connection section 1311 other than the avoidance opening 1312 may be accommodated in the first hole 1352.
Similarly, if the third aperture 1372 is also provided with a shielding region, the second connecting segment 1321 may also be provided with an escape opening to escape the shielding region of the third aperture 1372. Alternatively, if the third hole 1372 is not provided with a shielding region, the second connection segment 1321 may not be provided with a relief opening.
In some embodiments, other connection manners may be used between the first connection tube 131 and the first hole 1352. Fig. 10 shows another possible schematic cross-sectional view of the thermal management device 13 according to an embodiment of the present application, where the thermal management device 13 shown in fig. 10 may be an alternative form of the cross-sectional view of the thermal management device 13 shown in fig. 5, and the cross-section shown in fig. 10 corresponds to the direction of the cross-section shown in fig. 5, i.e. the cross-section shown in fig. 10 passes through the first connection pipe 131 and the second connection pipe 132 of the thermal management device 13 and is perpendicular to the length direction Y of the thermal management device 13.
As shown in fig. 10, the first plate 135 has a first protrusion structure 1354 protruding toward the first connection pipe 131, the first protrusion structure 1354 surrounding at least a partial region of the first hole 1352 and surrounding at least a partial region of the first connection section 1311. The first protrusion 1354 is disposed around at least a portion of the first hole 1352, that is, the first protrusion 1354 may serve as a further extension area of the first hole 1352, and thus, the first protrusion 1354 may further increase the area of the contact area between the first plate 135 and the first connection pipe 131, thereby improving the connection strength between the first connection pipe 131 and the first hole 1352 of the first plate 135. For example, the fixed connection between the first connection pipe 131 and the first hole 1352 may be achieved by welding, and then the first connection section 1311 is accommodated in the first protrusion structure 1354 and in the first hole 1352, so that the area of the weldable area between the first connection pipe 131 and the first hole 1352 may be increased, thereby improving welding strength and welding efficiency.
In some embodiments, the first protrusion structure 1354 and other areas of the embodiments of the present application may be an integrally formed structure, or may be a separate structure, which is not limited thereto.
Similarly, the third plate 137 may be provided with a second protrusion structure 1373 protruding toward the second connection tube 132, and the second protrusion structure 1373 of the third plate 137 surrounds at least a partial area of the third hole 1372 and at least a partial area of the second connection segment 1321 of the second connection tube 132, thereby increasing the area of a contact area when the second connection tube 132 is connected with the third hole 1372, thereby increasing structural strength.
It should be understood that fig. 5 and 10 are each described by taking the same example of the connection between the first plate 135 and the first connection pipe 131 and the connection between the third plate 137 and the second connection pipe 132, and the connection between the first plate 135 and the first connection pipe 131 and the connection between the third plate 137 and the second connection pipe 132 may be different.
For example, fig. 11 shows a schematic cross-sectional view of a thermal management device 13 according to an embodiment of the present application, where the thermal management device 13 shown in fig. 11 may be another alternative form of the cross-sectional view of the thermal management device 13 shown in fig. 5 or fig. 10, and the cross-section shown in fig. 11 corresponds to the direction of the cross-section shown in fig. 5 or fig. 10, that is, the cross-section shown in fig. 11 passes through the first connection pipe 131 and the second connection pipe 132 of the thermal management device 13 and is perpendicular to the length direction Y of the thermal management device 13. Fig. 12 is a partially exploded schematic view of a thermal management component 13 according to another embodiment of the present application, and the thermal management component 13 shown in fig. 12 may be the thermal management component 13 shown in fig. 11.
In the embodiment of the present application, the connection manner between the first plate 135 and the first connection pipe 131 and the connection manner between the third plate 137 and the second connection pipe 132 may also be different to adapt to different application scenarios. For example, as shown in fig. 11 and 12, the first plate 135 may not be provided with the first protrusion structure 1354 protruding toward the first connection pipe 131, and the first connection section 1311 of the first connection pipe 131 is received in the first hole 1352; and the third plate 137 is provided with a second protrusion structure 1373 protruding toward the second connection pipe 132, and the second connection section 1321 of the second connection pipe 132 is located in the second protrusion structure 1373 of the third plate 137.
Fig. 13 shows a schematic partial structure of the second plate 136 according to an embodiment of the present application, for example, the second plate 136 shown in fig. 13 may be a schematic partial structure of the second plate 136 included in the thermal management component 13 according to any one of fig. 3 to 12; fig. 14 is a schematic view showing a partial structure of the second plate 136, the second connection pipe 132, and the reinforcement pipe 133 in the thermal management unit 13 according to the embodiment of the present application, and fig. 15 is a schematic view showing a partial structure of the second plate 136, the first connection pipe 131, the second connection pipe 132, and the reinforcement pipe 133 in the thermal management unit 13 according to the embodiment of the present application, wherein the angles shown in fig. 14 and 15 are different, and the thermal management unit 13 shown in fig. 14 and 15 may be a partial schematic view of the thermal management unit 13 according to any one of the embodiments shown in fig. 3 to 12.
In the present embodiment, the second plate 136 is provided with a second aperture 1362, the second aperture 1362 extending through at least a portion of the first recessed area 1361, and the stiffening tube 133 extending through the second aperture 1362. As shown in fig. 13-15, a first recessed region 1361 may be used to form the flow channel 138, a second bore 1362 extending through at least a portion of the first recessed region 1361, and the stiffening tube 133 extending through the second bore 1362, whereby the stiffening tube 133 may communicate with the flow channel 138 through the second bore 1362 to inject fluid into the flow channel 138.
In some embodiments, a side of the second plate 136 facing the first plate 135 is provided with a shielding structure 1363, the shielding structure 1363 surrounding a partial region of the second aperture 1362, the shielding structure 1363 being adapted to shield at least a partial region of the second opening 1342 of the at least one opening 134. In particular, as shown in fig. 13-15, the shielding structure 1363 surrounds a partial region of the second hole 1362 and the reinforcing tube 133 penetrates the second hole 1362, and thus, the shielding structure 1363 may serve to shield at least a partial region of the second opening 1342 provided in at least one opening 134 of the reinforcing tube 133, the second opening 1342 may be any one of the at least one opening 134, and the shielding structure 1363 may shield one or more openings 134 of the reinforcing tube 133, i.e., the reinforcing tube 133 may include one or more second openings 1342. By adjusting the position and the size of the shielding structure 1363, the size of the second opening 1342 shielded by the shielding structure 1363 can be adjusted, and the shielding structure 1363 can be used for adjusting the speed and the flow of the fluid entering the flow channel 138 to meet different processing requirements because the fluid needs to enter the flow channel 138 through the second opening 1342.
In some embodiments, if the battery 10 includes a plurality of thermal management components 13 that are in communication with each other, for example, a plurality of thermal management components 13 aligned along the first direction X, when fluid is injected into the plurality of thermal management components 13, the fluid may be generally injected into the thermal management components 13 from the first connection pipe 131 of the first thermal management component 13, the fluid may also flow out from the second connection pipe 132 of the thermal management component 13 to the first connection pipe 131 of the next thermal management component 13, and so on, the fluid flows into each thermal management component 13 in turn. Considering that the fluid flows into each of the thermal management members 13 in turn, if the structures of the plurality of thermal management members 13 are not different, the flow rate of the front thermal management member 13 is larger than that of the rear thermal management member 13, i.e., the front thermal management member 13 is filled with the fluid in preference to the rear thermal management member 13, which has a larger time difference, which is detrimental to the efficiency of fluid injection of the plurality of thermal management members 13 as a whole.
Accordingly, the flow rate and velocity of fluid into the thermal management component 13 may be adjusted by adjusting the area of the corresponding second opening 1342 that is blocked by the blocking structure 1363 of each thermal management component 13. Specifically, in the case where the battery includes a plurality of thermal management members 13, the areas of the corresponding second openings 1342 shielded by the shielding structures 1363 provided with the plurality of thermal management members 13 are different. For example, the area of the corresponding second opening 1342 blocked by the blocking structure 1363 of the front thermal management component 13 may be provided to be larger, i.e., to reduce the flow and velocity of fluid into the front thermal management component 13 so that more fluid flows to the rear thermal management component 13; accordingly, the area of the corresponding second opening 1342 that is blocked by the blocking structure 1363 of the rearward thermal management component 13 is smaller, i.e., the flow rate and velocity of the fluid into the rearward thermal management component 13 is increased. For another example, for the plurality of thermal management components 13 arranged along the first direction X, the areas of the corresponding second openings 1342 blocked by the blocking structure 1363 of the first thermal management component 13 to the areas of the corresponding second openings 1342 blocked by the blocking structure 1363 of the last thermal management component 13 are gradually reduced in order along the order of fluid inflow, so as to reduce the flow rate and speed of the preceding thermal management component 13 and increase the flow rate and speed of the following thermal management component 13, so that the flow rate and speed of fluid flowing into the plurality of thermal management components 13 are relatively balanced, and further the efficiency of fluid injection of the plurality of thermal management components 13 is improved.
It should be appreciated that the difference in the area of the corresponding second openings 1342 that are blocked by the blocking structure 1363 providing a plurality of thermal management components 13 may be achieved in a variety of ways. For example, the second openings 1342 of the plurality of thermal management components 13 may be provided in the same shape and size for ease of machining and installation; in addition, the shielding structures 1363 of the plurality of thermal management components 13 may be provided to be different in size and position, so that the areas of the corresponding second openings 1342 shielded by the shielding structures 1363 of the plurality of thermal management components 13 may be made different.
In some embodiments, the second opening 1342 is the same opening as the first opening 1341, such that the location of the second opening 1342, i.e., the specific area shielded by the shielding structure 1363, can be positioned for ease of installation by the shielding region 1353 of the first aperture 1352; particularly in the case where the areas of the corresponding second openings 1342 blocked by the blocking structures 1363 of the plurality of thermal management components 13 are different, there is a difference between each thermal management component 13, and the position of the second openings 1342 may be located by the blocking regions 1353 to expedite the installation.
It should be appreciated that the second opening 1342 of the present embodiment may be any opening of the stiffening tube 133. For example, the second opening 1342 is an opening having the largest dimension along the circumferential direction W of the reinforcing pipe 133 among the at least one opening 134, which is convenient for adjusting the flow rate and speed of the fluid entering the thermal management component 13 on the one hand, and on the other hand, the position of the second opening 1342 can be quickly identified, so that the installation efficiency is improved, and the probability of the installation error is reduced.
Therefore, in the thermal management component 13 of the embodiment of the present application, since the first connection pipe 131 and the second connection pipe 132 are internally provided with the reinforcing pipe 133, the reinforcing pipe 133 is provided with at least one opening 134, and the fluid can flow into the thermal management component 13 through the at least one opening 134, the reinforcing pipe 133 can increase the structural strength of the thermal management component 13 at the first connection pipe 131 and the second connection pipe 132, thereby improving the structural stability and reliability of the thermal management component 13. The thermal management component 13 may include a first plate 135 and a second plate 136, wherein the second plate 136 may be provided with a shielding structure 1363, and the shielding structure 1363 may be used to shield the second opening 1342 of the at least one opening 134, thereby adjusting the flow rate and speed of the fluid entering the thermal management component 13 to flexibly set the flow rate and speed of the fluid flowing into the thermal management component 13 at different locations, thereby improving the efficiency of the fluid flowing into the thermal management component 13, and the processing and mounting efficiency of the battery 10.
Further, as shown in fig. 4 to 15, the side wall of the reinforcing pipe 133 of the thermal management part 13 of the embodiment of the present application may be provided with a plurality of openings 134, and the plurality of openings 134 may be provided in different sizes along the circumferential direction W of the reinforcing pipe 133. The first plate 135 of the thermal management component 13 is provided with a first aperture 1352, the first aperture 1352 being provided with a shielding region 1353, the shielding region 1353 being received in the first opening 1341 in the at least one opening 134 of the stiffening tube 133. The side of the second plate 136 of the thermal management component 13 facing the first plate 135 is provided with a shielding structure 1363, the shielding structure 1363 surrounding a partial region of the second aperture 1362, the shielding structure 1363 being adapted to shield at least a partial region of the second opening 1342 of the at least one opening 134. Also, the second opening 1342 and the first opening 1341 may be the same opening.
While the present application has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the present application. In particular, the technical features mentioned in the respective embodiments may be combined in any manner as long as there is no structural conflict. The present application is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions falling within the scope of the claims.
