- the immersion power battery thermal management system in the embodiment of the present invention includes a battery unit and a thermal management unit; wherein the battery unit includes a box body 1, a battery module 2 and a liquid cooling plate 3, the box body 1 is provided with an external liquid inlet 4 and an external liquid outlet 5, the liquid cooling plate 3 is provided with an internal liquid outlet 8, the liquid cooling plate 3 is located below the battery module 2, a liquid flow channel 6 is provided inside the liquid cooling plate 3, an immersion space 7 is formed inside the box body 1, the internal liquid outlet 8 is connected between the liquid flow channel 6 and the immersion space 7, the external liquid inlet 4 is connected to the liquid flow channel 6, and the external liquid outlet 5 is connected to the immersion space 7; the thermal management unit includes a controller 18 and an external circulation path formed outside the box body 1, the external circulation path is connected from the external liquid outlet 5 to the external liquid inlet 4, and the external circulation path includes an expansion tank 9 connected in sequence from the external liquid outlet 5 , a circulation pump 10, a water cooling unit 11, a heater 12 and a check valve 13, the expansion

- the serpentine flow channels in this embodiment are in the form of four parallel channels.
- the liquid entering from the external liquid inlet 4 enters the liquid cooling plate 3 from the four channels at the same time. After the interior of the liquid cooling plate 3 is filled with liquid, the liquid overflows from the internal liquid outlet 8 to the immersion space 7.
- Thermally conductive silicone is provided between the battery module 2 and the liquid cooling plate 3 to enhance heat transfer therebetween.
- Internal liquid outlets 8 are provided at both ends of the liquid cooling plate 3, and the thermally conductive silicone should not block the nearby internal liquid outlets 8.
- the system also has a self-circulation mode and a static mode.
- the controller 18 controls the system to switch between the cooling mode, the heating mode, the self-circulation mode and the static mode, as follows:
- the circulation loop is filled with heat transfer liquid, including the interior of the power battery unit box 1 .
- the controller 18 When the cooling mode is running, the controller 18 will send an operation instruction to the circulation pump 10 and the water cooling unit 11 to start working. At this time, the heat generated by the battery module 2 will gradually be transferred to the immersion liquid in the power battery unit. Driven by the circulation pump 10, the liquid enters the external circulation path through the external liquid port 5. Since the battery module 2 will generate gas overflow in the internal cavity of the power battery unit during use, if it cannot be removed in time, it will seriously affect the system's heat transfer efficiency and the safety of the power battery. Therefore, the liquid enters the external circulation path, first through the expansion tank 9 to remove the generated gas, and then the liquid flows through the filter 15 to filter out the impurities carried out of the power battery unit, and the liquid then flows into the circulation pump 10.
- the liquid enters the water cooling unit 11, transfers the heat absorbed from the battery module 2 to the water cooling unit 11, and reduces the temperature of the liquid itself.
- the heater 12 does not work at this time, so the liquid does not change after passing through the heater 12, and directly flows into the check valve 13.
- the check valve 13 is used to prevent the liquid from flowing back, and finally flows into the liquid flow channel 6 of the liquid cooling plate 3 through the external liquid inlet 4, and overflows from the internal liquid outlet 8, gradually replacing the original liquid filled in the power battery unit, and taking away the heat, gas and impurities generated during the use of the battery module 2, thereby forming a complete power battery cooling circuit.
- the controller 18 monitors the temperature of the liquid entering and leaving the power battery unit through the first temperature sensor 16 and the second temperature sensor 17, and then adjusts the operating power of the circulation pump 10 and the water cooling unit 11.
- the controller 18 will send an operation instruction to the circulation pump 10 and the heater 12 to start working.
- Other operation methods are the same as the cooling mode.
- the controller 18 will send an operation instruction to the circulation pump 10 to start it working, so as to achieve uniform temperature inside the power battery unit through the flow of liquid. At this time, the water cooling unit and the heater are not working.
- the thermal management system In static mode, the thermal management system is at rest and does not operate.
- the liquid overflows from just above the serpentine flow channel in the liquid cooling plate 3, the overflowing fluid can directly immerse the battery module 2, and the liquid in the serpentine flow channel of the liquid cooling plate 3 can indirectly exchange heat with the bottom of the module, thereby solving the problem of poor heat exchange uniformity caused by the bottom of the battery module 2 not being able to be immersed, and ensuring good heat exchange uniformity of the battery module 2.
- the liquid outlet of the power battery unit is arranged at the upper part of the box body 1.
- the generated gas will undoubtedly accumulate in the upper part of the box body 1. Setting the liquid outlet at the upper part of the box body 1 can more conveniently discharge the generated gas together with the liquid in the box, greatly reducing the risk of thermal safety accidents of the power battery unit.
- the present invention provides an expansion tank 9 in the system loop, and the connection is close to the outgoing liquid port 5 of the power battery unit, which can quickly and effectively absorb the gas brought out of the liquid from the inside of the power battery unit and discharge it into the atmosphere, thereby alleviating the harm caused by the gas to the system.
- the serpentine flow channel used in this design is a parallel four-channel, and the liquid enters from both ends of the serpentine flow channel to ensure the temperature consistency of the liquid inside the liquid cooling plate 3.
- the inner liquid outlet 8 is set above the serpentine flow channel at both ends of the liquid cooling plate 3 to ensure that the liquid enters the power battery Temperature uniformity of the unit cavity.
- the present invention provides a water cooling unit 11 and a heater 12 in the system loop, so that the system has the functions of cooling and heating the power battery, thereby improving the adaptability of the power battery to operate in high and low temperature harsh working conditions.
- a liquid level sensor is provided in the expansion tank 9, and a signal acquisition line is provided to connect to the controller 18.
- the liquid flow rate in the system can be properly adjusted by the change of the liquid level, and a refilling signal can also be given, which is conducive to the efficient and safe use of the thermal management system.
- the interior of the liquid cooling plate 3 is divided into two liquid inlet spaces.
- the external liquid inlets 4 are connected one-to-one with the liquid flow channels 6 of the liquid inlet spaces to allow liquid to circulate from the outside into the interior of the liquid cooling plate 3.

- the interior of the liquid cooling plate 3 is divided into the same number of liquid inlet spaces, and the external liquid inlet 4 is connected to the liquid inlet space one-to-one, and each liquid inlet space is provided with a liquid flow channel 6.
