TECHNICAL FIELD

[0001] The utility model relates to direct cooling plate technical field especially relates to a temperature equalization direct cooling plate assembly. BACKGROUND

[0002] In the energy storage system, a plurality of battery packs generate a large amount of heat when running, and when the ambient temperature is high, the battery cell temperature is easy to be higher than the normal working first temperature value of the battery cell, and when the ambient temperature is low, the battery cell temperature is easy to be lower than the normal working second temperature value of the battery cell. When the battery cell temperature is higher than the normal working first temperature value of the battery cell, the energy storage system needs to dissipate heat for the battery cell in the running battery pack. When the battery cell temperature is lower than the normal working second temperature value of the battery cell, the energy storage system needs to supply heat for the battery cell in the running battery pack. With the development of thermal management technology, battery direct cooling technology (direct cooling plate) is an important means of battery pack thermal management. Battery direct cooling technology is a cooling method for battery thermal management, which directly absorbs the heat generated by the battery to maintain the battery within a suitable working temperature range.

[0041] Embodiment one

[0042] The embodiment provides a uniform temperature direct cooling plate assembly, and the uniform temperature direct cooling plate assembly is good in uniformity and low in cost.

[0043] Specifically, as Figure 1 And Figure 2As shown, the vapor chamber cooling plate assembly includes a vapor chamber plate 300, a flat plate 500, and a flow channel plate 400. The vapor chamber plate 300 is a phase change vapor chamber plate and includes several effective portions; exemplarily, the effective portions can be one, two, or four, etc. The flat plate 500 is sandwiched between the vapor chamber plate 300 and the flow channel plate 400. The inner surface of the flow channel plate 400 facing the flat plate 500 has several circulating channels for allowing a flowing medium (e.g., refrigerant) to flow into or out of the flow channel plate 400. Each circulating channel corresponds to one of the effective portions; that is, the number of circulating channels is the same as the number of effective portions of the vapor chamber plate 300, and they conduct heat in a one-to-one manner. The flow channel plate 400 has connection positions for connecting the flat plate 500, which are located at the intervals of the circulating channels to avoid the circulating channels.

[0044] Based on the above design, the vapor chamber 300, as a heat-conducting device, enables higher heat conduction efficiency due to the phase change principle. The flow channel plate 400, as a heat dissipation device, connects the vapor chamber 300 and the flow channel plate 400 via a flat plate 500. Compared to a direct connection between the flow channel plate 400 and the vapor chamber 300, this connection is easier to operate. Furthermore, the connection between the flat plate 500 and the flow channel plate 400 is achieved through pre-reserved connection points located at the intervals of several circulating flow channels. This avoids the circulating flow channels, preventing bulging of the vapor chamber direct cooling plate assembly and eliminating the need for welding areas between adjacent flow channels within the circulating flow channels, thereby improving the temperature uniformity of the vapor chamber direct cooling plate assembly. The vapor chamber 300 is divided into multiple effective sections corresponding to the number of circulating flow channels, which not only improves the temperature uniformity of large-area vapor chamber direct cooling plate assemblies but also saves the overall area of ​​the effective sections of the vapor chamber 300, reducing costs.

[0045] In this embodiment, the heat spreader 300 includes four effective parts, and the number of circulation channels is also four. The phase change heat spreader 300 is prior art and will not be described in detail here.

[0046] Optionally, the inner surface of the flow channel plate 400 facing the heat spreader 300 is divided into four quadrants by its own width axis (along the x direction in the figure) and length axis (along the y direction in the figure). Specifically, in Figure 2 In the diagram, quadrant one is located in the upper right corner, quadrant two in the upper left corner, quadrant three in the lower left corner, and quadrant four in the lower right corner. Each quadrant contains a circulating flow channel. The two circulating flow channels in quadrants one and two are connected in parallel to form the first flow channel structure, and the two circulating flow channels in quadrants three and four are connected in parallel to form the second flow channel structure. Distributing the four circulating flow channels according to the four quadrants improves the temperature uniformity of this flow channel plate 400, thereby improving the temperature uniformity of the uniform temperature direct cooling plate assembly.

[0047] It should be noted that the x direction in the figure is the length direction of the flow channel plate 400, and the y direction is the width direction of the flow channel plate 400. The reserved connection position on the flow channel plate 400 is on the length and width center axes; the connection position is provided with a threaded hole, a bolt is arranged through the threaded hole to connect the flat plate 500 and the flow channel plate 400, improve the stress uniformity of the flow channel plate 400, and then improve the uniformity of the adhesion of the flow channel plate 400 and the flat plate 500, and finally improve the uniformity of the uniform cooling plate assembly.

[0048] Optionally, the flat plate 500 and the uniform plate 300 are separately manufactured and then welded.

[0049] Optionally, as shown in Figure 6 , Figure 7 and Figure 8 , the uniform cooling plate assembly further comprises a connecting head 600, the connecting head 600 is arranged through the flat plate 500 and connected with the flow channel plate 400, the connecting head 600 is provided with a liquid inlet 610 and a liquid outlet 620, and the liquid inlet 610 and the liquid outlet 620 are respectively communicated with the circulating flow channels.

[0050] Further, the two circulating flow channels in the first flow channel structure are symmetrical about the length center axis, and the two circulating flow channels in the second flow channel structure are also symmetrical about the length center axis; the first flow channel structure and the second flow channel structure are symmetrical about the width center axis. The symmetrical first flow channel structure and the second flow channel structure are arranged along the width direction of the flow channel plate 400, which improves the uniformity of the relatively wide flow channel plate 400 along the width direction, and the first flow channel structure and the second flow channel structure are respectively divided by the length center axis, which improves the uniformity of the flow channel plate 400 along the length direction.

[0051] Further, the first flow channel structure and the second flow channel structure share one liquid inlet 610 and one liquid outlet 620.

[0052] In the embodiment, the liquid inlet 610 and the liquid outlet 620 are both located on the side of the flow channel plate 400 away from the length center axis and close to the width center axis. Since the end of the flow channel plate 400 where the liquid inlet 610 and the liquid outlet 620 are located is related to the connection of other components, and the end of the flow channel plate 400 where the liquid inlet 610 and the liquid outlet 620 are located is not an effective part of heat dissipation, the position of the liquid inlet 610 and the liquid outlet 620 is not located at the center position in the width direction of the flow channel plate 400, resulting in that the flow channel of the end is not completely symmetrical about the width center axis, but only approximately symmetrical.

[0053] Optionally, the first flow channel structure comprises a main inlet flow channel 1, parallel one-zone inlet flow channels and two-zone inlet flow channels, parallel one-zone return flow channels and two-zone return flow channels, and a main return flow channel 2 connected in sequence. The main return flow channel 2 extends along the circumference of the flow channel plate 400 and is used for the flowing medium to flow out of the flow channel plate 400. The one-zone return flow channels surround the length and width central axes of the one quadrant, and the two-zone return flow channels surround the width central axes of the two quadrants and are away from the length central axes. The main inlet flow channel 1 is located in the two quadrants away from the length central axes and extends along the length central axes, and is used for the flowing medium to flow into the flow channel plate 400. The one-zone inlet flow channels and the two-zone inlet flow channels respectively enter the one quadrant and the two quadrants and extend out after being spirally wound, and are connected with the one-zone return flow channels and the two-zone return flow channels respectively. Since the second flow channel structure is symmetrical to the first flow channel structure about the width central axes, the main return flow channel 2 extends along the circumference of the flow channel plate 400, that is, the two main return flow channels 2 of the first flow channel structure and the second flow channel structure are arranged around the circumference of the flow channel plate 400, which can shorten the length of the main return flow channel 2 to shorten the flowing distance of the flowing medium in the main return flow channel 2, thereby reducing the pressure drop of the flow channel plate 400 and improving the temperature equalization effect and heat exchange capacity of the temperature equalization cold plate assembly. Meanwhile, the one-zone return flow channels and the two-zone return flow channels are located on the circumferential sides of the respective quadrants, which can shorten the length of the one-zone return flow channels and the two-zone return flow channels to shorten the flowing distance of the flowing medium in the one-zone return flow channels and the two-zone return flow channels, thereby reducing the pressure drop of the flow channel plate 400 and further improving the temperature equalization effect and heat exchange capacity of the temperature equalization cold plate assembly. In addition, the flow channel arrangement of the first flow channel structure and the second flow channel structure makes the flowing medium flow into the flow channel plate 400 from the middle of the flow channel plate 400 and then flow to the edges of the flow channel plate 400 in the width direction, enter the respective quadrants after being spirally wound, flow out of the respective quadrants along the edges of the respective quadrants, and then flow out of the edges of the flow channel plate 400. This arrangement shortens the flowing distance of the flowing medium and increases the flowing distance of the flowing medium, so that the entire flow channel is arranged in a "more inlet and less outlet" manner, which reduces the flowing speed of the flowing medium and increases the flowing speed of the flowing medium, thereby improving the heat exchange efficiency of the flow channel plate 400.

[0054] As Figures 3 to 5As shown, the first return flow channel 21 is located at the side of the quadrant toward the width mid-axis and is in communication with the main return flow channel 2. The first return flow channel 21 includes the first return branch 211 and the second return branch 212 which are in parallel and are located at the side of the quadrant toward the length mid-axis. The first return branch 211 and the second return branch 212 are in communication with the first return flow channel 21. The first inlet flow channel 11 is in communication with the main inlet flow channel 1 and is in communication with the first inlet branch and the second inlet branch at the side of the flow channel plate 400 along the direction of the width mid-axis. The first inlet branch is in communication with the first return branch 211 after being spirally wound at the half part of the quadrant away from the width mid-axis. The second inlet branch is in communication with the second return branch 212 after being spirally wound at the half part of the quadrant toward the width mid-axis. The circulation flow channels in the quadrant are similar to the circulation flow channels on the whole flow channel plate 400. The return flow path of the flowing medium is short, and the temperature uniformity in the quadrant is improved. The circulation flow channels in the quadrant are divided into two parts (one part is the first inlet branch and the other part is the second inlet branch) along the width direction of the flow channel plate 400 at the edge corner of the quadrant. The temperature uniformity in the quadrant is improved, and the inlet flow velocity of the flowing medium is reduced to improve the heat exchange efficiency.

[0055] Further, the first inlet branch includes the first connecting channel 111 located at the side away from the length mid-axis, the first wave channel 1111 and the second wave channel 1112. The two ends of the first wave channel 1111 and the second wave channel 1112 after being connected in parallel are connected with the first return branch 211 and the first connecting channel 111 respectively. That is, the circulation flow channels in the half part of the quadrant away from the width mid-axis are also divided into two parts (one part is the first wave channel 1111 and the other part is the second wave channel 1112). The “more inlet and less outlet” layout of the circulation flow channels in the range is further added, and the local temperature uniformity and heat exchange efficiency of the flow channel plate 400 are improved. The second inlet branch includes the second connecting channel 112 located at the side away from the length mid-axis, the third wave channel 1121 and the fourth wave channel 1122. The two ends of the third wave channel 1121 and the fourth wave channel 1122 after being connected in parallel are connected with the second return branch 212 and the second connecting channel 112 respectively. That is, the circulation flow channels in the half part of the quadrant toward the width mid-axis are also divided into two parts (one part is the third wave channel 1121 and the other part is the fourth wave channel 1122). The “more inlet and less outlet” layout of the circulation flow channels in the range is further added, and the local temperature uniformity and heat exchange efficiency of the flow channel plate 400 are improved. Finally, the temperature uniformity and heat exchange efficiency of the whole quadrant are further improved.

[0056] Similarly, in order to improve the uniformity and heat exchange efficiency in the second quadrant, the second zone return flow channel includes a second return flow channel 22 and a third return branch 221 and a fourth return branch 222 which are both in communication with the second return flow channel 22, the third return branch 221 and the fourth return branch 222 are parallel and located on the side of the second quadrant away from the lengthwise central axis, and the second return flow channel 22 is located on the side of the first quadrant and the second quadrant towards the widthwise central axis and in communication with the main return flow channel 2; the second zone inlet flow channel includes a second inlet flow channel 12, a third inlet branch and a fourth inlet branch, the third inlet branch and the fourth inlet branch are parallel, the second inlet flow channel 12 is in communication with the main inlet flow channel 1 and in communication with the third inlet branch and the fourth inlet branch along the direction of the widthwise central axis to the lengthwise central axis, the third inlet branch is in communication with the third return branch 221 after being spirally wound in the half of the second quadrant away from the widthwise central axis, and the fourth inlet branch is in communication with the fourth return branch 222 after being spirally wound in the half of the second quadrant towards the widthwise central axis.

[0057] Similarly, further, the third inlet branch includes a third connecting channel 121 located on the side towards the lengthwise central axis, a fifth wave channel 1211 and a sixth wave channel 1212, the two ends of the fifth wave channel 1211 and the sixth wave channel 1212 after being connected in parallel are connected with the third return branch 221 and the third connecting channel 121 respectively; the fourth inlet branch includes a fourth connecting channel 122 located on the side towards the lengthwise central axis, a seventh wave channel 1221 and an eighth wave channel 1222, the two ends of the seventh wave channel 1221 and the eighth wave channel 1222 after being connected in parallel are connected with the fourth return branch 222 and the fourth connecting channel 122 respectively.

[0058] In the embodiment, a plurality of flow channels are arranged between the first inlet flow channel 11 and the second inlet flow channel 12 and the main inlet flow channel 1 to increase the flow channel density on the flow channel plate 400.

[0059] Alternatively, the turning portions of the first wave channel 1111, the second wave channel 1112, the third wave channel 1121, the fourth wave channel 1122, the fifth wave channel 1211, the sixth wave channel 1212, the seventh wave channel 1221 and the eighth wave channel 1222 are all fully designed. The turning portions of the wave flow channels are folded and fully designed, which can avoid the problem of insufficient local heat exchange capacity caused by the small heat exchange area of the turning portions of the wave flow channels.

[0060] Alternatively, the first wave channel 1111 and the second wave channel 1112 have the same direction and are arranged in parallel and at intervals; the third wave channel 1121 and the fourth wave channel 1122 have the same direction and are arranged in parallel and at intervals; the fifth wave channel 1211 and the sixth wave channel 1212 have the same direction and are arranged in parallel and at intervals; and the seventh wave channel 1221 and the eighth wave channel 1222 have the same direction and are arranged in parallel and at intervals. The two wave flow channels have the same direction and are arranged in parallel, which increases the consistency of the heat exchange effect of the two wave flow channels and further improves the local uniformity.

[0061] In the embodiment, the first wave channel 1111, the second wave channel 1112, the third wave channel 1121, the fourth wave channel 1122, the fifth wave channel 1211, the sixth wave channel 1212, the seventh wave channel 1221 and the eighth wave channel 1222 are shaped as rectangular waves which are convex-concave along the width center axis direction and extend along the length center axis direction, and the flowing medium flows along the width center axis direction. In order to ensure the temperature uniformity, the spacing between each channel along the width center axis direction along the length center axis direction is the same. The spacing between two wave channels (the first wave channel 1111 and the second wave channel 1112, the third wave channel 1121 and the fourth wave channel, the fifth wave channel 1211 and the sixth wave channel 1212, or the seventh wave channel 1221 and the eighth wave channel 1222) is the spacing along the width center axis direction. Of course, the spacing cannot be too large, and the two wave channels must be alternately distributed along the length center axis direction.
