Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thermal management equipment, in particular to a flow channel plate and a coolant side integrated module. Background Art
[0002] Compared to traditional fuel-powered vehicles, new energy vehicles (NEVs) have fewer engines and transmissions and more batteries, motors, and electronic controls. This makes the operating modes of the vehicle's coolant-side integrated modules more complex and diverse, and exposes them to harsher operating conditions. The coolant-side integrated modules in NEVs must not only regulate the passenger compartment's daily temperature, but also maintain the normal operating temperatures of the batteries and motors, ensuring safety and efficiency. They also coordinate and manage heat flow across various components to minimize energy consumption.
[0003] In order to meet the complex and diverse working modes of new energy vehicles, the vehicle's coolant side integrated module has added sub-components such as electronic compressors, plate heat exchangers, electronic expansion valves, electronic water valves, and water pumps. It is mainly divided into two major cycles: refrigerant cycle and cooling water cycle. Among them, the design of the coolant side flow plate is the focus and difficulty.
[0004] The coolant-side manifold primarily provides mounting structures for various valves, pumps, and sensors, as well as complex coolant flow paths. When the coolant-side integrated module is operating, coolant circulates directly through the flow paths and components, heating or cooling the required components. However, when gas enters the coolant, especially during non-vacuum filling, it forms bubbles that circulate within the system along with the coolant, severely impacting heat exchange efficiency. This can also affect sensor measurement accuracy, which in turn impacts control accuracy, ultimately impacting vehicle range, comfort, and even safety. Utility Model Content

The height of the second interface is higher than the height of the first interface.
[0009] Optionally, a diversion partition is provided on the first flow channel for separating the first flow channel into a second flow channel and a third flow channel, the first interface is located on the second flow channel, and the second interface is located on the third flow channel.

[0018] As described above, the flow channel plate of the present invention has the following beneficial effects:

The first interface is used for being connected with a water pump, and the second interface is used for being connected with a kettle. The height of the second interface is higher than that of the first interface. The cooling liquid flows in the first flow channel towards the first interface and the second interface. Since the second interface is located in front of the first interface along the flow direction of the fluid in the first flow channel, the cooling liquid can pass through the second interface first. Since the height of the second interface is higher than that of the first interface, the gas bubbles in the cooling liquid will float upwards and enter the expansion kettle through the second interface under the action of the buoyancy, and finally, the gas bubbles are exhausted.

[0027] See Figures 1 to 3 , this embodiment provides a flow channel plate, including a flow channel plate body 1 and an exhaust group. The exhaust group includes a first flow channel 11, a first interface 12 and a second interface 13. The first flow channel 11 is arranged in the flow channel plate body 1. The first interface 12 and the second interface 13 are arranged on the flow channel plate body 1. The first interface 12 and the second interface 13 can be arranged on the same side of the flow channel plate body 1, or on opposite sides of the flow channel plate body 1. The first interface 12 and the second interface 13 are respectively connected to the first flow channel 11. A fluid is arranged in the first flow channel 11 for the fluid to pass through. In this embodiment, the fluid is a coolant. The first interface 12 is used to connect to a water pump, and the second interface 13 is used to connect to a kettle. The height of the second interface 13 is higher than the height of the first interface 12. The second interface 13 is located before the first interface 12 along the flow direction of the fluid in the first flow channel 11, that is, the second interface 13 is connected before the first interface 12 along the flow direction of the fluid in the first flow channel 11.
[0028] In the embodiment, the flow channel plate comprises a flow channel plate body 1 and an exhaust group. The exhaust group comprises a first flow channel 11 arranged in the flow channel plate body 1, a first interface 12 and a second interface 13 arranged on the flow channel plate body 1, and the first interface 12 and the second interface 13 are respectively communicated with the first flow channel 11. The first interface 12 is used to be connected with a water pump, and the second interface 13 is used to be connected with a kettle, and the height of the second interface 13 is higher than that of the first interface 12. The cooling liquid flows in the first flow channel 11 towards the first interface 12 and the second interface 13. Since the second interface 13 is located in front of the first interface 12 along the flow direction of the fluid in the first flow channel 11, the cooling liquid can pass through the second interface 13 first. Since the height of the second interface 13 is higher than that of the first interface 12, the gas bubbles in the cooling liquid will float up under the action of buoyancy, enter the expansion kettle through the second interface 13, and finally be discharged into the air, so that the gas bubbles in the cooling liquid can be completely removed. The degassed cooling liquid is then sucked into the water pump through the second interface 13, so as to avoid that when the gas is mixed into the cooling liquid, the gas will circulate in the system in the form of bubbles with the cooling liquid, which affects the heat exchange efficiency; at the same time, it also avoids affecting the accuracy of sensor measurement, thereby improving the accuracy of control, and further improving the endurance, comfort and safety of the whole vehicle.
[0029] In some embodiments, as shown in Figure 1 and Figure 2 , a flow separation baffle 17 is arranged on the first flow channel 11, which is used to separate the first flow channel 11 to form a second flow channel 14 and a third flow channel 15, and the first interface 12 is located on the second flow channel 14 and the second interface 13 is located on the third flow channel 15. Arranging the first interface 12 and the second interface 13 on two different flow channels respectively can make the gas bubbles in the cooling liquid more accurately enter the kettle through the second interface 13, so as to make the exhaust more thorough. Arranging the flow separation baffle 17 between the second flow channel 14 and the third flow channel 15 can avoid that the cooling liquid is directly sucked into the water pump through the first interface 12 under inertia, which causes exhaust failure, thereby improving the exhaust effect.
[0030] In some embodiments, as shown in Figure 1As shown, a guide structure is provided at the connection between the first flow channel 11 and the third flow channel 15. The inner wall on the opposite side of the first flow channel 11 and the diverter baffle 17 is a guide portion 19 that bends away from the first interface 12. A guide structure is formed between the guide portion 19 and the diverter baffle 17, and the third flow channel 15 also bends away from the first interface 12. The kettle is not shown in the figure. The kettle is arranged directly above the first flow channel 11, so the third flow channel 15 is also arranged directly above the first flow channel 11. Under the guidance and inertia of the guide structure, the coolant in the first flow channel 11 flows in a direction away from the first interface 12. The bubbles in the coolant enter the kettle through the second interface 13 under the action of buoyancy. The coolant flows downward under the action of gravity and is sucked into the water pump through the first interface 12. Through the above structure, the coolant can be moved away from the first interface 12 and the second flow channel 14 under the action of the guide structure, so that the bubbles in the coolant can enter the kettle through the second interface 13 with higher efficiency, thereby improving the degassing effect of the coolant.
[0031] In some embodiments, as Figure 1 and Figure 2 As shown, the first interface 12 is located at the end of the second flow channel 14, so that the coolant will be sucked into the water pump through the first interface 12 only when it flows to the end of the second flow channel 14. If there are still bubbles in the coolant at this time, the time for the bubbles to float up through buoyancy is increased, thereby preventing the bubbles from entering the water pump.
[0032] In some embodiments, as Figure 2 As shown, multiple exhaust groups can be provided, and the multiple exhaust groups can be interconnected or disconnected. With more exhaust groups, bubbles in the same amount of coolant can be exhausted in a shorter time, improving exhaust efficiency.
[0033] In some embodiments, as Figure 2 As shown, the exhaust groups are arranged in two groups, one higher and one lower. The second interfaces 13 of the two exhaust groups are arranged to overlap. The third flow channel 15 of the exhaust group located at the lower position communicates with the second flow channel 14 of the exhaust group located at the upper position, and they have an overlapping common section 16. This structure can save internal space of the manifold plate body 1, and while increasing the number of exhaust groups, it can also avoid the bloated structure of the manifold plate body 1 and reduce the volume of the manifold plate body 1.
[0034] In some embodiments, as Figure 2As shown, the first port 12 of the upper exhaust group is located directly below the first flow channel 11 of the same exhaust group. Both inner walls of the common section 16 are curved toward the first port 12 of the upper exhaust group. The first flow channel 11 and second flow channel 14 of the upper exhaust group form a V- or U-shape, meaning that the first port 12 of the upper exhaust group, located at the end of the second flow channel 14, is located to the right of the lower exhaust group. This structure is equivalent to combining a water pump and a kettle, saving space. The degassed coolant in the second flow channel 14 of the upper exhaust group flows downward, while the aerated coolant in the third flow channel 15 of the lower exhaust group flows upward, potentially interfering with each other. The curved shape of the common section 16 guides the coolant in the second flow channel 14 of the upper exhaust group. After impacting the inner wall of the common section 16, the coolant in the second flow channel 14 of the upper exhaust group flows away from the lower exhaust group, preventing the two coolant streams from impacting each other and affecting exhaust efficiency.
[0035] In some embodiments, as Figure 2 As shown, a baffle 18 is disposed between the second flow channels 14 of the two exhaust groups. Baffle 18 extends along the second flow channel 14 of the upper exhaust group. Baffle 18 prevents convection of coolant between the two exhaust groups, which could affect exhaust quality and efficiency. It also prevents undegassed coolant from the upper exhaust group from being directly drawn into the lower first port 12, causing exhaust failure.
[0036] In some embodiments, the second flow channel 14 and the third flow channel 15 of the exhaust group located below are both arranged along the height direction of the flow channel plate body 1. The height direction of the flow channel plate body 1 is also Figures 1 to 3 It can increase the speed of bubbles rising in the coolant in the third flow channel 15, and can also increase the speed of the coolant after degassing due to gravity, thereby improving the overall degassing and exhaust efficiency.
[0037] In some embodiments, as Figure 3 As shown, the first flow channel 11 is arranged along the length direction of the flow channel plate body 1, and the length direction of the flow channel plate body 1 is also Figures 1 to 3 The first interface 12 and the second interface 13 are connected to different sides of the first flow channel 11. Specifically, the first interface 12 and the second interface 13 are connected to both sides of the first flow channel 11 along the thickness direction of the flow channel plate body 1. The second interface 13 is connected to the top of the first flow channel 11, and the first interface 12 is connected to the bottom of the first flow channel 11. In the direction of coolant flow in the first flow channel 11, the second interface 13 is located before the first interface 12. The above structure is relatively simple and easy to manufacture.
[0038] The embodiment also provides a cooling liquid side integrated module, which comprises the flow channel plate.
[0039] The above embodiment only illustrates the principle and effect of the utility model, and is not used to limit the utility model. Any person skilled in the art can modify or change the above embodiment without departing from the spirit and category of the utility model. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the utility model should be covered by the claims of the utility model.
