The following describes specific embodiments of the present utility model in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the utility model, are not intended to limit the utility model.
An embodiment of the first aspect of the present utility model is to provide a heat exchange plate, as shown in fig. 1 and 2, including a first heat exchange runner 1, a second heat exchange runner 2, a split runner 3 and a converging runner 4, where the split runner 3 is provided with a water inlet 31, the converging runner 4 is provided with a water outlet 41, the first heat exchange runner 1 and the second heat exchange runner 2 are both communicated between the split runner 3 and the converging runner 4, and the depth of the first heat exchange runner 1 is smaller than the depth of the second heat exchange runner 2.
When in use, as shown in fig. 1, the cooling liquid can enter the flow dividing flow passage 3 from the water inlet 31, and then enter the first heat exchanging flow passage 1 and the second heat exchanging flow passage 2 after being divided by the flow dividing flow passage 3, and as the depth of the first heat exchanging flow passage 1 is smaller than that of the second heat exchanging flow passage 2, the flow velocity of the cooling liquid in the first heat exchanging flow passage 1 and the flow velocity of the cooling liquid in the second heat exchanging flow passage 2 are different, the heat dissipation effect generated by the two heat exchanging flow passages is different, and one of the internal cooling liquid with higher flow velocity is opposite to the heat concentrated area of the battery, so that the heat in the heat concentrated area is taken away rapidly.
Compared with the prior art, the heat exchange plate is provided with the first heat exchange flow channel 1 and the second heat exchange flow channel 2 with different flow rates of the internal cooling liquid, so that the heat of the battery heat concentration area can be dissipated in a targeted manner, and the cooling resources can be efficiently utilized.
In some embodiments, the width dimension of the second heat exchange flow channel 2 is 8-30mm, and the width dimension of the first heat exchange flow channel 1 is preferably larger than the width dimension of the second heat exchange flow channel 2.
The width dimension of the second heat exchange flow channel 2 may be understood as a direction perpendicular to the direction of the flow of the cooling liquid in the second heat exchange flow channel 2, and the direction perpendicular to the depth dimension of the second heat exchange flow channel 2 on the cutting surface is the direction of the width dimension of the second heat exchange flow channel 2. The width dimension of the first heat exchange flow channel 1 is the same.
In some other embodiments, the width dimension of the first heat exchange flow channel 1 may also be smaller than the width dimension of the second heat exchange flow channel 2.
The size of the first heat exchange flow channel 1 can be comprehensively determined according to the heating position of the battery cell 7 or the module.
In some embodiments, as shown in fig. 2 and 3, the first heat exchange flow channel 1 and the second heat exchange flow channel 2 are formed between the upper plate surface 51 and the lower plate surface 61 of the heat exchange plate, that is, a cavity is formed between the upper plate surface 51 and the lower plate surface 61, and the cavity includes the first heat exchange flow channel 1 and the second heat exchange flow channel 2, so that the forming of the first heat exchange flow channel 1 and the second heat exchange flow channel 2 is facilitated.
Specifically, as shown in fig. 4, the lower plate surface 61 is flush with the surfaces of the first heat exchange flow passage 1 and the second heat exchange flow passage 2.
It can be appreciated that, when in use, the lower plate 6 corresponding to the lower plate surface 61 can be directly contacted with the electric core 7, and the distance between one side, close to the lower plate surface 61, of the first heat exchange flow channel 1 and the second heat exchange flow channel 2 and the electric core 7 is the same by the arrangement, so that the flow velocity of cooling liquid in the two heat exchange flow channels can be positively correlated with the heat dissipation effect, and a person can conduct targeted rapid heat dissipation on the heat concentration area of the electric core 7 according to the flow velocity of the cooling liquid in the two heat exchange flow channels.
In some embodiments, the lower plate surface 61 is planar at the position corresponding to the first heat exchange flow channel 1 and the second heat exchange flow channel 2; the upper plate surface 51 is curved at the position corresponding to the first heat exchange flow channel 1 and the second heat exchange flow channel 2.
The cooperation of above-mentioned plane and curved surface can make down the first heat transfer runner 1 and the second heat transfer runner 2 that the degree of depth is different between face 61 and the face 51, can make first heat transfer runner 1 and the second heat transfer runner 2 form planar structure down to the one side of face 61 down simultaneously, and one side that first heat transfer runner 1 and second heat transfer runner 2 deviate from face 61 down is formed with rugged structure, does not influence the area of contact of each heat transfer runner and electric core 7.
In some embodiments, the flow dividing channel 3 is formed between the upper plate surface 51 and the lower plate surface 61 of the heat exchange plate, and the depth of the flow dividing channel 3 is equal to the depth of the second heat exchange channel 2, so that the cooling liquid in the flow dividing channel 3 more smoothly enters the second heat exchange channel 2.
Specifically, the surface of the upper plate surface 51 corresponding to the top end of the flow dividing channel 3 is flush with the surface corresponding to the top end of the second heat exchanging channel 2, and the surface of the lower plate surface 61 corresponding to the bottom end of the flow dividing channel 3 is flush with the surface corresponding to the bottom end of the second heat exchanging channel 2. Therefore, the cooling liquid in the split flow channel 3 cannot generate the level difference when entering the second heat exchange flow channel 2, and the cooling liquid can enter the second heat exchange flow channel 2 more smoothly.
In some embodiments, the converging flow passage 4 is formed between the upper plate surface 51 and the lower plate surface 61 of the heat exchange plate, and the depth of the converging flow passage 4 is equal to the depth of the second heat exchange flow passage 2, so that the cooling liquid in the second heat exchange flow passage 2 more smoothly enters the converging flow passage 4.
Specifically, the surface of the upper plate surface 51 corresponding to the top end of the converging flow passage 4 is flush with the surface corresponding to the top end of the second heat exchange flow passage 2, and the surface of the lower plate surface 61 corresponding to the bottom end of the converging flow passage 4 is flush with the surface corresponding to the bottom end of the second heat exchange flow passage 2. So that the cooling liquid in the second heat exchange flow channel 2 can not generate the level difference when entering the converging flow channel 4, and the cooling liquid can enter the converging flow channel 4 more smoothly.
In some embodiments, as shown in fig. 3 and 4, the heat exchanger plate comprises an upper plate 5 and a lower plate 6, wherein:
The lower plate 6 is a flat plate, and the surface of the upper plate 5 facing the lower plate 6 is an upper plate surface 51. In use, the surface of the lower plate 6 facing away from the upper plate 5 can be in direct contact with the cells 7, which is designed as a flat plate capable of ensuring the contact area between the respective flow channels and the cells 7.
The upper plate 5 is a plate body with a concave groove structure, and the surface of the lower plate 6 facing the upper plate 5 is a lower plate surface 61. After the upper plate 5 is connected with the lower plate 6, a cavity can be formed between the upper plate 5 and the lower plate 6 due to the groove structure concavely arranged on the upper plate 5, and the cavity can comprise the first heat exchange flow channel 1, the second heat exchange flow channel 2, the flow dividing flow channel 3 and the confluence flow channel 4, so that the flow channels can be conveniently formed.
The concave direction of the groove structure on the upper plate 5 is a direction away from the lower plate 6.
The upper plate 5 may be formed by stamping from sheet metal, and the upper plate 5 and the lower plate 6 are welded together using a brazing process.
The first heat exchange flow channels 1 and the second heat exchange flow channels 2 may be configured in multiple numbers, and the number of the first heat exchange flow channels 1 may be greater than, less than or equal to the number of the second heat exchange flow channels 2. Along the flow direction of the cooling liquid in the first heat exchange flow channel 1, the side of the first heat exchange flow channel 1 is not communicated with the second heat exchange flow channel 2, and can be partially or everywhere communicated with the second heat exchange flow channel 2.
In some embodiments, the first heat exchange flow channel 1 is located on at least one side of the second heat exchange flow channel 2 along the flow direction of the cooling liquid in the first heat exchange flow channel 1.
In some embodiments, as shown in fig. 4, the surfaces of the lower plate surface 61 corresponding to the first heat exchange flow channel 1 and the second heat exchange flow channel 2 are spaced from the surfaces of the upper plate surface 51 corresponding to the first heat exchange flow channel 1 and the second heat exchange flow channel 2, so that the first heat exchange flow channel 1 communicates with the side surface of the second heat exchange flow channel 2.
The side surfaces of the first heat exchange flow channel 1 and the second heat exchange flow channel 2 are as follows: along the flow direction of the cooling liquid in the first heat exchange flow channel 1, the side surface of the first heat exchange flow channel 1 and along the flow direction of the cooling liquid in the second heat exchange flow channel 2, the side surface of the second heat exchange flow channel 2.
The arrangement can enable the side surfaces of the first heat exchange flow channel 1 and the second heat exchange flow channel 2 to be completely communicated along the flowing direction of the cooling liquid in the two flow channels, the cooling liquid in the flow dividing flow channel 3 can only enter the cooling liquid from the end part of the first heat exchange flow channel 1 or only enter the cooling liquid from the end part of the second heat exchange flow channel 2, and the flow velocity of the cooling liquid in the two heat exchange flow channels can be adjusted according to the difference of the positions of the entering cooling liquid, so that different heat dissipation effects are realized.
In addition, the arrangement does not occupy more space to separate the first heat exchange flow channel 1 from the second heat exchange flow channel 2, and the processing cost is lower.
In at least one embodiment, as shown in fig. 3, the first heat exchange channels 1 are configured into two, the second heat exchange channels 2 are configured into three, one ends of the three second heat exchange channels 2 are communicated with the flow dividing channels 3, the other ends of the three second heat exchange channels are communicated with the converging channels 4, and the three second heat exchange channels 2 are uniformly arranged at intervals. One of the first heat exchange flow passages 1 is positioned on one side of the whole of the three second heat exchange flow passages 2 and is completely communicated with the side of the adjacent second heat exchange flow passage 2, and the other first heat exchange flow passage 1 is positioned on the other side of the whole of the three second heat exchange flow passages 2 and is completely communicated with the side of the adjacent second heat exchange flow passage 2.
In some embodiments, as shown in fig. 3, the water inlet 31 is located in the middle of the flow-dividing channel 3. When the second heat exchange flow passages 2 are configured into three, the arrangement can enable the flow velocity of the second heat exchange flow passages 2 positioned in the middle to be the fastest, so that the middle of the heat exchange plate has a good heat dissipation effect.
In some embodiments, as shown in fig. 3, the water outlet 41 is located in the middle of the converging flow passage 4, and when the second heat exchange flow passages 2 are configured into three, the water outlet 41 can accelerate the discharge of the cooling liquid in the second heat exchange flow passage 2 located in the middle, so as to further improve the heat dissipation effect in the middle of the heat exchange plate.
It should be noted that, the water inlet 31 and the water outlet 41 may be located at one end of the heat exchange plate, or may be located at two ends of the heat exchange plate as shown in fig. 3.
An embodiment of the second aspect of the present utility model is to provide a battery, as shown in fig. 5, where the battery provided by the embodiment of the second aspect of the present utility model includes a cell 7 and the heat exchange plate, the cell 7 has a heat collecting region, and one of the first heat exchange flow channel 1 and the second heat exchange flow channel 2 with a larger flow rate of the cooling liquid is disposed opposite to the heat collecting region.
In the battery provided by the embodiment of the second aspect of the utility model, the heat exchange plate can be attached to the top surface of the battery core 7 to radiate the battery core 7, and through reasonable arrangement of the first heat exchange flow channel 1 and the second heat exchange flow channel 2, the heat concentration area of the battery core 7 can be radiated in a targeted manner, so that the battery has a better radiating effect and efficiently utilizes cooling resources.
The heating size of the battery cell 7 is related to the position of the battery cell 7, and the heat exchange plate can adjust the sizes of the first heat exchange flow channel 1 and the second heat exchange flow channel 2 according to the heating size of the battery cell 7, so that the flow rates of the two heat exchange flow channels can be controlled, the battery cell 7 is fully cooled, the temperature difference between the battery cells 7 is reduced, and the full release and output of battery energy are facilitated.
In some embodiments, as shown in fig. 5, when the first heat exchange flow channel 1 is communicated with the side surface of the second heat exchange flow channel 2, and the cooling liquid at the water inlet 31 enters from the second heat exchange flow channel 2 and is discharged from the second heat exchange flow channel 2 to the water outlet 41, the flow rate of the cooling liquid in the second heat exchange flow channel 2 is faster than the flow rate of the cooling liquid in the first heat exchange flow channel 1, and the second heat exchange flow channel 2 is opposite to the heat concentration area.
In the above embodiment, the coolant in the split flow channel 3 enters the first heat exchange flow channel 1 from the second heat exchange flow channel 2, and the coolant in the first heat exchange flow channel 1 enters the converging flow channel 4 from the second heat exchange flow channel 2.
In some embodiments, when the first heat exchange flow channel 1 is communicated with the side surface of the second heat exchange flow channel 2, and the cooling liquid at the water inlet 31 enters from the first heat exchange flow channel 1 and is discharged from the second heat exchange flow channel 2 to the water outlet 41, the flow rate of the cooling liquid in the first heat exchange flow channel 1 is faster than the flow rate of the cooling liquid in the second heat exchange flow channel 2, and the first heat exchange flow channel 1 is opposite to the heat concentration area.
In the above embodiment, the cooling liquid in the split flow channel 3 enters the second heat exchange flow channel 2 from the first heat exchange flow channel 1, and the cooling liquid in the first heat exchange flow channel 1 enters the converging flow channel 4 from the second heat exchange flow channel 2.
At present, most new energy vehicles have fast middle temperature rise and slow four-side temperature rise of the battery cell 7 under the running working condition. Under the condition that the battery cell 7 is slowly charged and discharged, the heat generated in the continuous discharging process is generated by uniform power because the power is not large, and the flow velocity of the middle part of the heat exchange plate is required to be faster than the flow velocity of the periphery. As shown in fig. 5, in this case, the coolant at the water inlet 31 enters from the second heat exchange flow channel 2, and is suitably discharged from the second heat exchange flow channel 2 to the water outlet 41, and the second heat exchange flow channel 2 is disposed opposite to the portion where the heat generation amount of the battery cell 7 is greatest.
If the heat exchange plate is used on a vehicle type needing quick release and quick charge, the battery cell 7 is continuously charged and discharged with high power, the heating value of the battery cell 7 is in direct proportion to the charging and discharging power, and the heating value is huge. At this time, the cooling liquid at the water inlet 31 needs to enter from the first heat exchange flow channel 1 and be discharged from the second heat exchange flow channel 2 to the water outlet 41, and the first heat exchange flow channel 1 and the part with the largest heat productivity of the battery cell 7 are arranged oppositely. The large-flow water inlet 31 enables the cooling liquid to flow in the first heat exchange flow channel 1 rapidly, and can take away heat emitted by the battery cell 7 rapidly.
An embodiment of the third aspect of the present utility model is to provide an electric apparatus, where the electric apparatus provided by the embodiment of the third aspect of the present utility model includes the heat exchange plate or the battery.
According to the electric equipment provided by the embodiment of the third aspect of the utility model, through different depths of the first heat exchange flow channel 1 and the second heat exchange flow channel 2 on the heat exchange plate and different flow rates of the cooling liquid in the heat exchange plate, different heating parts on the battery core 7 can dissipate heat at different heat dissipation speeds, and long-term effective use of the electric equipment is facilitated.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
