Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fluid delivery, in particular to a water-cooled machine shunt device and a test system. BACKGROUND

[0002] As an important cooling equipment in industrial production, experimental test and air conditioning system, the water-cooled machine is widely used in occasions with high requirements for temperature control accuracy and cooling capacity (such as battery pack electrical performance test). The traditional water-cooled machine system usually adopts one-to-one water supply mode, that is, one water-cooled machine corresponds to one set of water equipment or test station. However, with the diversification of test tasks and the demand for improvement of resource utilization, a single water-cooled machine often cannot meet the requirements of multi-station or multi-system simultaneous operation. If a water-cooled machine is configured for each test station, not only the investment cost is high, but also the equipment utilization rate is low, resulting in resource waste. Therefore, it has important practical significance and application value to develop an efficient and reliable water-cooled machine shunt technology.

[0003] The above information disclosed in the background section is only included to enhance the understanding of the background of the present disclosure, and therefore can contain information that is not prior art known to those of ordinary skill in the art. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a water-cooled machine shunt device and a test system to solve the problem of delayed battery pack electrical performance test due to insufficient number of water-cooled machines.

[0005] The present application adopts the following technical solutions:

[0006] In a first aspect, the present application provides a water-cooled machine shunt device. The water-cooled machine shunt device comprises:

[0007] A first communication structure comprising a first confluence port and at least two first shunt ports in communication with the first confluence port;

[0008] A second communication structure comprising a second confluence port and at least two second shunt ports in communication with the second confluence port and corresponding to the at least two first shunt ports;

[0009] Wherein, the corresponding first shunt port and the second shunt port are connected with a load branch, the first confluence port is connected with the liquid outlet of the water-cooled machine, and the second confluence port is connected with the liquid return port of the water-cooled machine.

[0010] The present application connects the liquid-cooled machine and the load branch by setting a communication structure with one confluence port and multiple shunt ports, which can effectively expand the number of load branches between the liquid outlet and the liquid return port of the liquid-cooled machine, realize multi-way shunting and recycling of the water-cooled machine cooling liquid, and can cool multiple loads at the same time, improve the test efficiency and the flexibility of the system, and facilitate expansion and maintenance.

[0011] As a possible implementation manner, the number of the first shunt ports is two; and the first communication structure comprises a first tee joint.

[0012] In the present application, when only two cooling paths are needed, the tee joint structure can simplify the pipeline design, reduce the cost, and facilitate the installation and maintenance, and the structure is compact, thereby improving the practicability of the system.

[0013] As a possible implementation manner, the first tee joint is a Y-shaped tee joint.

[0014] In the present application, the Y-shaped tee joint can effectively reduce the fluid resistance and the problem of uneven shunting, and improve the flow consistency of each branch, which is beneficial to obtaining balanced cooling effect for each load.

[0015] As a possible implementation manner, the number of the first shunt ports is more than two; the first communication structure is a first multi-tee joint with one more interface than the number of the first shunt ports, or is formed by at least two second tee joints through a cascading connection manner.

[0016] The cascading tee joint is adopted in the present application, which facilitates to expand more branches, flexibly cope with the cooling demand of different numbers of loads, and improves the expansibility and universality of the system.

[0017] As a possible implementation manner, the number of the second shunt ports is two; and the second communication structure is a third tee joint.

[0018] The tee joint structure is adopted as the liquid return interface in the present application, which can maintain the consistency of the inlet and outlet liquid shunting, simplify the pipeline layout, and facilitate the installation and maintenance.

[0019] As a possible implementation manner, the third tee joint is a Y-shaped tee joint.

[0020] The Y-shaped tee joint is adopted as the liquid return port in the present application, which can reduce the resistance when the fluid flows back, ensure the smooth flow of each path, and help to improve the overall performance of the cooling system.

[0021] As a possible implementation manner, the number of the second shunt ports is more than two; and the second communication structure is formed by at least two fourth tee joints through a cascading connection manner.

[0022] The liquid return interface also adopts the cascading tee joint in the present application, which ensures the smooth liquid return of the multi-branch system, avoids the blockage of the backflow, and better adapts to the multi-load test scene.

[0023] As a possible implementation manner, the load branch comprises a measured load to be water-cooled and a flow meter connected in series with the measured load.

[0024] Alternatively, the water chiller shunt device further comprises at least two pipelines corresponding to the at least two first shunt ports, and the pipelines are connected in series with the measured load to be water cooled and a flow meter.

[0025] The application adds a flow meter in each pipeline to monitor the flow of cooling liquid in each pipeline in real time, facilitate cooling effect control, abnormality detection and data recording, and improve system reliability and intelligent level. The application specifies the specific installation mode of each component, which is helpful for standardized installation and standardized design, and facilitates system replication and popularization and application.

[0026] In a second aspect, the application further provides a test system comprising at least two load branches, a water chiller and the water chiller shunt device realized by any of the above implementation manners.

[0027] As a possible implementation manner, the load branch comprises a measured load to be water cooled, and the measured load is a battery pack.

[0028] The beneficial effects of the above second aspect can be referred to the first aspect or any of the possible implementation manners of the first aspect, which will not be described here. On the basis of the implementation manners provided in the above aspects, the application can be further combined to provide more implementation manners.

[0035] The terms used in the implementation part of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application. Some concepts that may be involved in the present application will be briefly introduced below.

[0036] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The drawings show typical embodiments of the present application. However, the present application can be implemented in many different forms, and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, and are not limitations of the technical solutions of the present application. In the case of no conflict, the technical features in the embodiments of the present application and the embodiments can be combined with each other.

[0037] The following will be described in detail respectively. It should be noted that the order of the following embodiment descriptions is not intended to limit the priority order of the embodiments.

[0038] Please refer to Figure 1 , Figure 1 A structure schematic diagram of a water-cooled machine shunt device provided by an embodiment of the present application is shown. The present application provides a water-cooled machine shunt device and a test system. The water-cooled machine shunt device comprises:

[0039] The first communication structure 101 comprises a first confluence port 1011, and at least two first shunt ports 1012 in communication with the first confluence port 1011;

[0040] The second communication structure 102 comprises a second confluence port 1021, and at least two second shunt ports 1022 in communication with the second confluence port 1021 and corresponding to the at least two first shunt ports 1012;

[0041] Among them, the corresponding first shunt port 1012 and the second shunt port 1022 are connected with a load branch 103, the first confluence port 1011 is connected with the liquid outlet of the water-cooled machine, and the second confluence port 1021 is connected with the liquid return port of the water-cooled machine.

[0042] For example, the load branch 103 refers to an independent cooling loop (such as a water pipe cooling different devices) through which the water flow passes, and there is a measured load (such as a battery pack) to be cooled on the loop. The first communication structure 101 includes a first converging port 1011 and at least two first diverging ports 1012, wherein each first diverging port 1012 is in communication with the first converging port 1011 and corresponds to a load branch 103. It can be understood that the cooling liquid of the water chiller flows out of the first converging port 1011 and then flows to different load branches 103 through the first diverging ports 1012, thereby achieving the distribution of the cooling liquid of the water chiller.

[0043] In addition, after the cooling liquid completes the cooling task on the load branch 103, it needs to flow back to the water chiller, and therefore the second communication structure 102 is for backflow. The second communication structure 102 includes a second converging port 1021 and at least two second diverging ports 1022, wherein each second diverging port 1022 is in communication with the second converging port 1021 and corresponds to a load branch 103. The cooling liquid flowing through each load branch 103 can flow into the second converging port 1021 through the second diverging ports 1022 and then return to the water chiller.

[0044] It is worth noting that the load branch 103 is connected between the corresponding first diverging port 1012 and the corresponding second diverging port 1022, the first converging port 1011 is connected with the liquid outlet of the water chiller, and the second converging port 1021 is connected with the liquid return port of the water chiller.

[0045] In some embodiments, the number of first diverging ports 1012 is two; the first communication structure 101 includes a first three-way joint.

[0046] For example, when the first diverging port 1012 is only two (i.e., the load branch 103 is only two), the first communication structure 101 can be implemented by a three-way joint, including but not limited to a Y-shaped three-way joint, a T-shaped three-way joint, etc.

[0047] In some embodiments, the first three-way joint is a Y-shaped three-way joint.

[0048] For example, when the first diverging port 1012 is only two (i.e., the load branch 103 is only two), the first three-way joint used by the first communication structure 101 can be a Y-shaped three-way joint.

[0049] In some embodiments, the number of first diverging ports 1012 is greater than two; the first communication structure 101 is a first multi-way joint with one more interface than the number of first diverging ports 1012, or is composed of at least two second three-way joints through a cascading connection mode.

[0050] Exemplarily, when the number of the first shunt ports 1012 is one, two, or even more (i.e., the number of the load branches 103 is three, four, or even more), the first communication structure 101 can be formed by at least two three-way joints, and the connection mode between the three-way joints can be a cascade mode.

[0051] In some embodiments, the number of the second shunt ports 1022 is two; and the second communication structure 102 is a third three-way joint.

[0052] Exemplarily, when the number of the second shunt ports 1022 is two (i.e., the number of the load branches 103 is two), the second communication structure 102 can be implemented by a three-way joint, including but not limited to a Y-shaped three-way joint, a T-shaped three-way joint, and the like.

[0053] In some embodiments, the third three-way joint is a Y-shaped three-way joint.

[0054] Exemplarily, when the number of the second shunt ports 1022 is two (i.e., the number of the load branches 103 is two), the third three-way joint adopted by the second communication structure 102 can be a Y-shaped three-way joint.

[0055] In some embodiments, the number of the second shunt ports 1022 is greater than two; the second communication structure 102 is a second multi-way joint with a number of interfaces being one more than the number of the second shunt ports 1022, or the second communication structure 102 is formed by at least two fourth three-way joints through a cascade connection mode.

[0056] Exemplarily, when the number of the second shunt ports 1022 is one, two, or even more (i.e., the number of the load branches 103 is three, four, or even more), the second communication structure 102 can be formed by at least two three-way joints, and the connection mode between the three-way joints can be a cascade mode.

[0057] In some embodiments, the load branch 103 includes a to-be-water-cooled measured load and a flow meter connected in series with the measured load.

[0058] Alternatively, the water-cooling machine shunt device further includes at least two pipelines corresponding to the at least two first shunt ports 1012, and the pipelines are connected in series with the to-be-water-cooled measured load and the flow meter.

[0059] Exemplarily, each load branch 103 includes a measured load (e.g., a battery pack in an electrical performance test) that needs to be cooled and a flow meter connected in series with the measured load. The flow meter is used to measure the flow rate of the cooling liquid flowing through the branch in real time, and is a key component for monitoring and guaranteeing the water flow of each load branch 103 in the water-cooling system, which helps to ensure the safe operation, performance optimization, and fault protection of the system.

[0060] Or, the water chiller shunt device further comprises a pipeline corresponding to the first shunt port 1012, each pipeline corresponds to a first shunt port 1012, so there are at least two pipelines, and each pipeline is connected in series with the measured load to be cooled and the flow meter.

[0061] In some embodiments, the water chiller shunt device can also be applied to a test system comprising at least two load branches 103, a water chiller, and the water chiller shunt device of any of the above embodiments.

[0062] For example, the test system can be applied in the electrical performance test of a battery pack, but is not limited to, comprising at least two load branches 103 (such as the branch composed of the battery pack and the flow meter), a water chiller, and any of the above-mentioned water chiller shunt devices, to achieve efficient cooling and improve test efficiency.

[0063] In some embodiments, the load branch 103 comprises a measured load to be water-cooled, and the measured load is a battery pack.

[0064] For example, the load branch 103 comprises a measured load to be cooled, and the measured load can be but is not limited to a battery pack.

[0065] Please refer to Figure 2 , Figure 2 A structure diagram of a water chiller shunt device based on a Y-type tee joint one-to-two provided by an embodiment of the present application is shown.

[0066] As Figure 2 shown, the water chiller shunt device based on a Y-type tee joint one-to-two comprises a first Y-type tee joint 201, a second Y-type tee joint 202, a first load branch 2031, a second load branch 2032, a water chiller 204, and an external circulation pump 205.

[0067] It should be noted that the liquid outlet of the water chiller 204 is connected with the external circulation pump 205 and the first Y-type tee joint 201, and the liquid return port of the water chiller 204 is connected with the second Y-type tee joint 202, wherein the first Y-type tee joint 201 serves as a first communication structure, the second Y-type tee joint 202 serves as a second communication structure, and the external circulation pump 205 is used to push the cooling liquid to circulate in the cooling loop (i.e. the load branch).

[0068] In addition, the first load branch 2031 and the second load branch 2032 each comprise a measured load and a flow meter, both flow meters are connected with the first Y-type tee joint 201 and the measured load, and the measured load is also connected with the second Y-type tee joint 202.

[0069] It can be understood that the first Y-type tee joint 201 can serve as a first communication structure to split the cooling liquid flowing out of the water cooler and then flow to different load branches; the second Y-type tee joint 202 can serve as a second communication structure to combine the cooling liquid flowing through different load branches and then flow into the liquid return port of the water cooler.

[0070] Referring to Figure 3 , Figure 3 Fig. 1 shows a structure schematic diagram of a one-to-three water cooler splitting device based on a four-way joint according to an embodiment of the present application.

[0071] As Figure 3 shown, the one-to-three water cooler splitting device based on a four-way joint includes a first four-way joint 301, a second four-way joint 302, a first load branch 3031, a second load branch 3032, a third load branch 3033, a water cooler 304, and an external circulation pump 305, wherein each load branch has a measured load and a flow meter connected in series with the measured load, one end of the flow meter is connected with the first four-way joint 301, the other end is connected with the measured load, and the end of the measured load not connected with the flow meter is connected with the second four-way joint 302.

[0072] It is worth noting that the second four-way joint 302 is connected with the liquid return port of the water cooler, and the first four-way joint 301 is connected with the liquid outlet port of the water cooler, and an external circulation pump is further connected at the liquid outlet port to push the cooling liquid to circulate in the cooling loop (i.e. the load branch).

[0073] It can be understood that the first four-way joint 301 can serve as a first communication structure to split the cooling liquid flowing out of the water cooler and then flow to different load branches; the second four-way joint 302 can serve as a second communication structure to combine the cooling liquid flowing through different load branches and then flow into the liquid return port of the water cooler.

[0074] It should be noted that in addition to the one-to-two and one-to-three splitting cases described above, a one-to-many water cooler splitting device can also be implemented, and here, a one-to-four case is taken as an example but is not limited to the one-to-four case. Figure 4

[0075] Referring to Figure 4 , Figure 4 Fig. 2 shows a structure schematic diagram of a one-to-many water cooler splitting device based on a Y-type tee joint according to an embodiment of the present application.

[0076] As Figure 4 ​As shown, the Y-shaped three-way joint-based one-to-multiple water-cooled machine shunt device includes a sixth Y-shaped three-way joint, four flow meters and four loads. Among them, three Y-shaped three-way joints can be combined into a first communication structure 401; another three Y-shaped three-way joints can be combined into a second communication structure 402; the four flow meters and the four loads form four load branches respectively, and constitute a branch 403.

[0077] It can be understood that the coolant of the water-cooled machine is divided into two through one Y-shaped three-way joint in the first communication structure 401, and is divided into four through the remaining two Y-shaped three-way joints in the first communication structure 401, so that the coolant is changed from one load branch (i.e. the cooling circuit formed by the flow meter and the load) to four load branches, and the one-to-multiple shunt of the coolant is completed.

[0078] In addition, after the coolant flows through the flow meter and the load, it will be converged through the three Y-shaped three-way joints in the second communication structure 402, and then flow back to the water-cooled machine liquid return port, thereby realizing the complete process of the water-cooled machine shunt.
