技术领域Technical field
本申请涉及汽车热管理集成模块技术领域，特别是涉及一种歧管组件及热管理集成模块。The present application relates to the technical field of automotive thermal management integrated modules, and in particular to a manifold assembly and a thermal management integrated module.
背景技术Background technique
随着技术的发展，电动汽车热管理***的功能越来越多，且电动汽车热管理***的集成化程度越来越高。因此，用于电动汽车热管理的热管理集成模块应运而生。通过热管理集成模块，大大减少了电动汽车热管理***所需的管路数量，并减少了电动汽车热管理***的故障率。With the development of technology, the thermal management system of electric vehicles has more and more functions, and the thermal management system of electric vehicles is becoming more and more integrated. Therefore, the thermal management integrated module for electric vehicle thermal management emerged as the times require. Through the thermal management integrated module, the number of pipelines required for the electric vehicle thermal management system is greatly reduced, and the failure rate of the electric vehicle thermal management system is reduced.
进一步地，电动汽车热管理***通常含有多个冷却液回路，每个冷却液回路中均至少设有一个液泵。为了提高热管理集成模块的集成度并减小热管理集成模块的体积，通常，相邻液泵的进液口之间距离比较近，并且，分别对应两个不同液泵的两个冷却液回路通常共享一个补液流道。当两个液泵运行时，液泵进液口附近会形成较大的漩涡，并且，漩涡会造成两个冷却液回路内流体的混合，当两个冷却液回路的温差较大时，则会造成其中一个冷却液回路内流体“热量”的损失，以及造成另一个冷却液回路内流体“冷量”的损失。并且，当两个冷却液回路中液泵的功率不同时，漩涡还会造成两个冷却液回路流量的波动。Furthermore, the thermal management system of electric vehicles usually contains multiple coolant circuits, and each coolant circuit is provided with at least one liquid pump. In order to improve the integration level of the thermal management integrated module and reduce the volume of the thermal management integrated module, usually the distance between the liquid inlets of adjacent liquid pumps is relatively close, and they correspond to two coolant circuits of two different liquid pumps. Usually share a rehydration channel. When two liquid pumps are running, a large vortex will be formed near the liquid pump inlet, and the vortex will cause the fluids in the two coolant circuits to mix. When the temperature difference between the two coolant circuits is large, it will Causes a loss of "heat" of the fluid in one of the coolant circuits, and a loss of "cooling" of the fluid in the other coolant circuit. Moreover, when the power of the liquid pumps in the two coolant circuits is different, the vortex will also cause fluctuations in the flow of the two coolant circuits.

请参阅图1-图4，为了解决液泵进液口处的漩涡导致相邻冷却液回路内的流体发生混合的问题，本申请提供一种歧管组件900及热管理集成模块10，歧管组件900设有分液通道910以及分别连通分液通道910的第一回流口920和第二回流口930，第一回流口920用于连通第一液泵100，第二回流口930用于连通第二液泵200。分液通道910包括第一端911和第二端912，分液通道910内设有分液隔板940，分液隔板940沿着预设方向将分液通道910的第一端911分隔成第一分支通道913和第二分支通道914，第一回流口920直接连通第一分支通道913，第二回流口930直接连通第二分支通道914，第一分支通道913通过分液通道910的第二端912连通第二分支通道914。Please refer to Figures 1 to 4. In order to solve the problem that the vortex at the liquid pump inlet causes the fluid in the adjacent coolant circuit to mix, the present application provides a manifold assembly 900 and a thermal management integrated module 10. The assembly 900 is provided with a liquid separation channel 910 and a first return port 920 and a second return port 930 that are respectively connected to the liquid separation channel 910. The first return port 920 is used to communicate with the first liquid pump 100, and the second return port 930 is used to communicate with the liquid separation channel 910. Second liquid pump 200. The liquid separation channel 910 includes a first end 911 and a second end 912. The liquid separation channel 910 is provided with a liquid separation partition 940. The liquid separation partition 940 separates the first end 911 of the liquid separation channel 910 into The first branch channel 913 and the second branch channel 914. The first return port 920 is directly connected to the first branch channel 913. The second return port 930 is directly connected to the second branch channel 914. The first branch channel 913 passes through the third branch channel 910 of the liquid separation channel 910. The two ends 912 are connected to the second branch channel 914.
需要说明的是，“沿着预设方向”可以是沿着预先设定的直线方向，还可以是沿着预先设定的曲线方向。在本实施例中，预设方向为沿着与分液通道910中心线平行或者相同的方向。It should be noted that “along the preset direction” may be along a preset straight line direction or along a preset curve direction. In this embodiment, the preset direction is parallel to or the same direction as the center line of the liquid dispensing channel 910 .
进一步地，需要说明的是，分液通道910的第一端911和第二端912并不局限于分液通道910的两个端部，在本实施例中，分液通道910被分为第一端911和第二端912，并且，第一端911和第二端912共同构成了整个分液通道910，也就是说，分液通道910除了第一端911，剩下的部分都属于第二端912。并且，分液通道910的第一端911和第二端912均没有长度限制，也即，第一端911的第二端912的分界点不一定在分液通道910的中心处，第一端911的第二端912的分界点可能在分液通道910的任意位置。Further, it should be noted that the first end 911 and the second end 912 of the liquid dispensing channel 910 are not limited to the two ends of the liquid dispensing channel 910. In this embodiment, the liquid dispensing channel 910 is divided into One end 911 and a second end 912, and the first end 911 and the second end 912 together constitute the entire liquid dispensing channel 910. That is to say, except for the first end 911, the remaining parts of the liquid dispensing channel 910 belong to the third end. Second end 912. Moreover, there is no length limit on the first end 911 and the second end 912 of the liquid dispensing channel 910. That is, the dividing point between the first end 911 and the second end 912 is not necessarily at the center of the liquid dispensing channel 910. The first end The dividing point of the second end 912 of 911 may be at any position of the liquid dispensing channel 910 .
更进一步地，需要说明的是，“第一回流口920直接连通第一分支通道913”中的直接连通是一个相对概念，相对而言，在本实施例中，由于第一分支通道913通过分液通道910 的第二端912连通第二分支通道914，因此，第二回流口930是通过第二分支通道914以及分液通道910的第二端912间接连通第一分支通道913的。同样的，“第二回流口930直接连通第二分支通道914”中的直接连通也是一个相对概念，在此不作赘述。Furthermore, it should be noted that the direct communication in "the first return port 920 is directly connected to the first branch channel 913" is a relative concept. Relatively speaking, in this embodiment, since the first branch channel 913 passes through the branch channel, The second end 912 of the liquid channel 910 is connected to the second branch channel 914. Therefore, the second return port 930 is indirectly connected to the first branch channel 913 through the second branch channel 914 and the second end 912 of the liquid distribution channel 910. Similarly, the direct connection in "the second return port 930 is directly connected to the second branch channel 914" is also a relative concept and will not be described in detail here.
由于分液隔板940沿着预设方向将分液通道910的第一端911分隔成第一分支通道913和第二分支通道914，第一回流口920直接连通第一分支通道913，第二回流口930直接连通第二分支通道914，第一分支通道913通过分液通道910的第二端912连通第二分支通道914。因此，第一回流口920无法直接连通第二回流口930，冷却液无法在第一回流口920和第二回流口930之间产生漩涡，也即，进入第一回流口920的冷却液难以和进入第二回流口930的冷却液发生混合。当分别进入第一回流口920和第二回流口930的冷却液的温差较大时，分别进入第一回流口920和第二回流口930的冷却液也不会因为发生混合导致进入第一回流口920的冷却液产生“热量”损失或者产生“冷量”损失，同样的，分别进入第一回流口920和第二回流口930的冷却液也不会因为发生混合导致进入第二回流口930的冷却液产生“热量”损失或者产生“冷量”损失。并且，当第一液泵100的功率和第二液泵200的功率不同时，分别进入第一回流口920和第二回流口930的冷却液也不会因为发生混合导致分别进入第一液泵100的流量和第二液泵200的流量发生波动。Since the liquid separation partition 940 separates the first end 911 of the liquid separation channel 910 into the first branch channel 913 and the second branch channel 914 along the preset direction, the first return port 920 is directly connected to the first branch channel 913 and the second branch channel 914 . The return port 930 is directly connected to the second branch channel 914 , and the first branch channel 913 is connected to the second branch channel 914 through the second end 912 of the liquid dispensing channel 910 . Therefore, the first return port 920 cannot directly communicate with the second return port 930, and the coolant cannot generate a vortex between the first return port 920 and the second return port 930. That is, the coolant entering the first return port 920 is difficult to mix with the second return port 930. The coolant entering the second return port 930 is mixed. When the temperature difference between the coolant entering the first return port 920 and the second return port 930 is relatively large, the coolant entering the first return port 920 and the second return port 930 will not enter the first return port due to mixing. The coolant in the port 920 produces "heat" loss or "cooling" loss. Similarly, the coolant entering the first return port 920 and the second return port 930 respectively will not enter the second return port 930 due to mixing. The coolant produces "heat" loss or "cooling" loss. Moreover, when the power of the first liquid pump 100 and the power of the second liquid pump 200 are different, the coolant entering the first return port 920 and the second return port 930 respectively will not enter the first liquid pump respectively due to mixing. The flow rate of 100 and the flow rate of the second liquid pump 200 fluctuate.
为了便于调节分别进入第一回流口920和第二回流口930的冷却液的流量，在一实施例中，如图4所示，歧管组件900还设有分别连通分液通道910的第一进液口950、第二进液口960和第三进液口970，第一进液口950直接连通第一分支通道913，第二进液口960直接连通第二分支通道914，第三进液口970直接连通分液通道910的第二端912。冷却液能够分别从第一进液口950、第二进液口960或者第三进液口970进入分液通道910，并且冷却液能够通过分液通道910分别进入第一回流口920和第二回流口930。In order to facilitate the adjustment of the flow rate of the coolant entering the first return port 920 and the second return port 930 respectively, in one embodiment, as shown in FIG. The liquid inlet 950, the second liquid inlet 960 and the third liquid inlet 970, the first liquid inlet 950 is directly connected to the first branch channel 913, the second liquid inlet 960 is directly connected to the second branch channel 914, and the third liquid inlet 950 is directly connected to the first branch channel 913. The liquid port 970 is directly connected to the second end 912 of the liquid dispensing channel 910 . The coolant can enter the liquid distribution channel 910 from the first liquid inlet 950, the second liquid inlet 960 or the third liquid inlet 970, and the coolant can enter the first return port 920 and the second liquid inlet 920 through the liquid separation channel 910 respectively. Return port 930.
进一步地，为了减少分别从第一进液口950、第二进液口960和第三进液口970回流的冷却液发生混合串热的串热量，在一实施例中，如图4所示，分液隔板940沿着预设方向延伸的长度M和分液通道910沿着预设方向的总长度N，满足以下关系式：0.22≤M/N≤0.65。如此，M/N≤0.65，有利于第一分支通道913通过分液通道910的第二端912连通第二分支通道914，进而有利于歧管组件900调节分别进入第一回流口920和第二回流口930的冷却液的回流量。M/N≥0.22，能够有效避免分别进入第一回流口920和第二回流口930的冷却液发生混合串热。可选地，M/N的值为0.31。Further, in order to reduce the cascading heat of the cooling liquid flowing back from the first liquid inlet 950, the second liquid inlet 960 and the third liquid inlet 970 respectively, in an embodiment, as shown in Figure 4 , the length M extending along the preset direction of the liquid separation partition 940 and the total length N of the liquid separation channel 910 along the preset direction satisfy the following relationship: 0.22≤M/N≤0.65. In this way, M/N≤0.65 is conducive to the first branch channel 913 connecting to the second branch channel 914 through the second end 912 of the liquid separation channel 910, which is conducive to the adjustment of the manifold assembly 900 into the first return port 920 and the second return port respectively. The return amount of coolant in the return port 930. M/N≥0.22 can effectively prevent the coolant entering the first return port 920 and the second return port 930 from mixing and heating. Optionally, the value of M/N is 0.31.
通常，歧管组件900内的串热模式包括以下三种模式：温度不同的冷却液分别从第一进液口950和第二进液口960进入分液通道910，或者，温度不同的冷却液分别从第一进液口950和第三进液口970进入分液通道910，或者，温度不同的冷却液分别从第二进液 口960和第三进液口970进入分液通道910。具体如下：Generally, the serial heating mode in the manifold assembly 900 includes the following three modes: coolant with different temperatures enters the liquid distribution channel 910 from the first liquid inlet 950 and the second liquid inlet 960 respectively, or coolant with different temperatures The cooling liquids with different temperatures enter the liquid separation channel 910 from the first liquid inlet 950 and the third liquid inlet 970 respectively, or the cooling liquids with different temperatures enter the liquid separation channel 910 from the second liquid inlet 960 and the third liquid inlet 970 respectively. details as follows:
Figure PCTCN2022142415-appb-000001
Figure PCTCN2022142415-appb-000001
需要说明的是，串热模式为“三+二”代表，第三进液口970和第二进液口960进液，串热模式为“二+一”代表，第二进液口960和第一进液口950进液，串热模式为“三+一”代表，第三进液口970和第一进液口950进液。It should be noted that the string heating mode is represented by "three + two", and the third liquid inlet 970 and the second liquid inlet 960 are filled with liquid. The string heating mode is represented by "two + one", and the second liquid inlet 960 and The first liquid inlet 950 is filled with liquid, the serial heating mode is represented by "three + one", and the third liquid inlet 970 and the first liquid inlet 950 are filled with liquid.
进一步地，需要说明的是，定义串热量小于或等于3000W满足要求。Further, it should be noted that the defined string heat is less than or equal to 3000W to meet the requirements.
通过测试实验得出以下数据表格1。由以下表格1分析可知，当M/N的值小于0.22时，三种串热模式下的串热量均大于3000W，当M/N的值大于或者等于0.22时，三种串热模式下的串热量均小于3000W。并且，为了便于第一分支通道913通过分液通道910的第二端912连通第二分支通道914，进而有利于歧管组件900调节分别进入第一回流口920和第二回流口930的冷却液的回流量，设置M/N的值小于0.65。The following data table 1 is obtained through test experiments. From the analysis in Table 1 below, it can be seen that when the value of M/N is less than 0.22, the string heat in the three string heating modes is greater than 3000W. When the value of M/N is greater than or equal to 0.22, the string heat in the three string heating modes is The heat is less than 3000W. In addition, in order to facilitate the first branch channel 913 to communicate with the second branch channel 914 through the second end 912 of the liquid distribution channel 910, and thereby facilitate the manifold assembly 900 to adjust the coolant entering the first return port 920 and the second return port 930 respectively.
