Detailed implementation manners

[0053] Next, in combination with the implementation manners of the present utility model, the technical solutions in the implementation manners of the present utility model will be clearly and completely described. Obviously, the described implementation manners are only a part of the implementation manners of the present utility model, rather than all of the implementation manners. Based on the implementation manners in the present utility model, all other implementation manners obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0054] As Figures 1 to 11 shown, the immersion battery module of the present utility model includes a container 1, a battery cell 2, a cooling channel member 3, an end plate 4, a liquid chiller 5, a liquid inlet pipe 6, a liquid return pipe 7, a side current shunt component 8, a middle current shunt component 9, an agitator 10 and a high-voltage box 11.

[0055] As Figure 1 , Figure 5 , Figure 6 and Figure 7 shown, the container 1 is filled with insulating coolant; a plurality of battery cells 2 and cooling channel members 3 are arranged in parallel in the container 1, and the plurality of battery cells 2 and cooling channel members 3 are arranged staggeredly with each other; the cooling channel member 3 is a through-type structure; at least two end plates 4 are provided to clamp the battery cells 2 and cooling channel members 3 arranged in parallel from both ends; a guiding mechanism is arranged in the container 1 to guide the insulating coolant to flow through the inside of the cooling channel member 3 and the surface of the battery cell 2.

[0056] In the above structure, in this battery module, the battery cells 2 and the cooling channel members 3 are arranged at intervals from each other. In this way, through the cooling channel members 3, effective support for the battery cells 2 can be achieved. At the same time, by relying on the end plates 4 to clamp the battery cells 2 and the cooling channel members 3, and supplemented with fasteners such as cable ties, the stability of the grouping can be ensured;

[0057] Since the cooling channel member 3 has a through structure, the circulation of the coolant can be ensured to quickly remove heat, thereby improving the heat dissipation efficiency;

[0058] At the same time, since a flow guiding mechanism is provided in the container, it can guide the coolant to flow through the inside of the cooling channel member and the surface of the battery cell 2, so that the coolant circulation is smooth and the heat dissipation effect is further improved.

[0059] As Figure 6 and Figure 7 shown, the cooling channel member 3 has a rectangular cylindrical structure, and a partition 31 is provided inside the cooling channel member 3 to form a flow channel 301;

[0060] With the above structure, the cooling channel member 3 has an overall rectangular cylindrical structure, so that it can effectively fit the large surface of the battery cell 2 to ensure the contact area. When the coolant flows through the flow channel 301, the heat transferred from the battery cell 2 to the cooling channel member 3 can be removed.

[0061] As Figure 1 and Figure 5 shown, the end plate 4 and the battery cell 2 and the cooling channel member 3 it clamps form a battery pack 100; a plurality of battery packs 100 are provided in the container 1, and the plurality of battery packs 100 are arranged in a rectangular array and are spaced apart from each other;

[0062] With the above structure, the battery cell 2, the cooling channel member 3 and the end plate 4 form a separate battery pack 100. This battery module includes several battery packs 100. When setting the battery packs 100, the battery packs 100 are arranged in an array and spaced apart to allow the coolant to flow through, thereby ensuring the heat dissipation effect.

[0063] As Figure 1 shown, the space in the container 1 is divided into a first accommodation cavity 101 and a second accommodation cavity 102. Among them, the battery pack 100 is arranged in the first accommodation cavity 101, and the first accommodation cavity 101 is filled with insulating coolant; the liquid cooler 5 is arranged in the second accommodation cavity 102, and the inlet and outlet of the liquid cooler 5 communicate with the first accommodation cavity 101;

[0064] With the above structure, the battery pack 100 is in the first accommodation cavity 101, while the liquid cooler 5 is arranged in the second accommodation cavity, and the inlet and outlet of the liquid cooler 5 communicate with the first accommodation cavity 101. In this way, during application, the liquid cooler 5 can be relied on to circulate the insulating coolant in the first accommodation cavity 101 and cool the coolant to ensure the heat dissipation efficiency.

[0065] As Figure 1As shown, a third accommodation cavity 103 is also spaced inside the container 1. Among them, the third accommodation cavity 103 is located on the periphery of the first accommodation cavity 101; the liquid inlet pipe 6 and the liquid return pipe 7 are arranged in the third accommodation cavity 103. One end of the liquid inlet pipe 6 is connected and communicated with the liquid outlet of the liquid chiller 5, and the other end is connected and communicated with the first accommodation cavity 101. One end of the liquid return pipe 7 is connected and communicated with the liquid inlet of the liquid chiller 5, and the other end is connected and communicated with the first accommodation cavity 101;

[0066] In the above structure, the liquid inlet pipe 6 and the liquid return pipe 7 for the interaction between the liquid chiller 5 and the coolant in the first accommodation cavity 101 are located in the independent third accommodation cavity 103, which can reduce the risk of liquid leakage and avoid component interference, so as to improve the convenience of the battery module grouping;

[0067] Specifically, the pipe orifice of the liquid inlet pipe 6 connected and communicated with the first accommodation cavity 101 is located on the upper side or the lower side of the battery pack 100; the pipe orifice of the liquid return pipe 7 connected and communicated with the first accommodation cavity 101 is located on the opposite side of the battery pack 100;

[0068] In the above structure, by arranging the liquid inlet pipe 6 and the liquid return pipe 7 relatively, convection can be realized to promote the circulation efficiency of the coolant.

[0069] When specifically arranged, two liquid inlet pipes 6 and two liquid return pipes 7 are provided respectively. One end of the liquid inlet pipe 6 is communicated with the liquid outlet of the liquid chiller 5, and the other end is connected to the bottom of the first accommodation cavity 101, and the two liquid inlet pipes 6 are arranged diagonally; one end of the two liquid return pipes 7 is communicated with the liquid inlet of the liquid chiller 5, and the other end is communicated with the top surface of the first accommodation cavity 101 and is arranged diagonally, so as to increase the flow distance of the coolant and thus improve the cooling effect.

[0070] As Figure 1 、 Figure 4 and Figure 8 , the diversion mechanism includes a side shunt member 8. The side shunt member 8 has a plate-like structure. The side shunt member 8 is arranged in contact with the inner wall of the container 1, and a first shunt tab 81 is provided on the side shunt member 8; the first shunt tab 81 is inclined relative to the side shunt member 8, and the first shunt tab 81 corresponds to the interval between the battery packs 100;

[0071] In the above structure, the side shunt member 8 is used to shunt the coolant. When the liquid chiller 5 supplies coolant into the first accommodation cavity 101, with the circulation, the first shunt tab 81 will shunt the coolant. At this time, a part of the coolant changes direction, changing from vertical flow to horizontal flow, so as to pass through between the battery packs 100 and achieve a better cooling effect.

[0072] As Figures 1 to 3 、 Figure 9 、 Figure 10As shown, the diversion mechanism further includes a middle diversion member 9. The middle diversion member 9 has a plate-like structure. The middle diversion member 9 is disposed between the battery packs 100, and a second diversion tab 91 is provided on the middle diversion member 9. The second diversion tab 91 is inclined relative to the middle diversion member 9, and the second diversion tab 91 corresponds to the interval between the battery packs 100. The middle diversion member 9 is provided with a through hole 901, and the through hole 901 corresponds to the flow channel 301.

[0073] In the above structure, similar to the side diversion member 8, the middle diversion member 9 can achieve the diversion of the coolant through the second diversion tab 91. At the same time, since the through hole 901 is provided on the middle diversion member 9, the coolant can pass through the through hole 901 of the middle diversion member 9 and flow through the flow channel 301 of the cooling flow channel member 3 to promote heat dissipation.

[0074] Specifically, a plurality of middle diversion members 9 are provided in the container 1, and the middle diversion members 9 are arranged in pairs. The two middle diversion members 9 arranged in pairs are arranged at an angle.

[0075] In the above structure, when the middle diversion member 9 is applied, the two middle diversion members 9 are used simultaneously. When the coolant flows into the angular space between the two middle diversion members 9, the coolant on both sides will form a turbulent flow by convection. The disturbance of the turbulent flow will form a horizontal flow in the horizontal axis and vertical axis on the horizontal plane. Each layer forms its own horizontal flow in the horizontal axis and vertical axis on the horizontal plane, forming a spatial horizontal flow network with multiple layers of horizontal flow in space.

[0076] In some embodiments, the side diversion member 8 and the middle diversion member 9 are made of a steel plate with a thickness of 2 mm, and the diversion tab is made by stamping the steel plate.

[0077] As Figure 1 and Figure 11 shown, the container 1 is the box body of an energy storage container. The agitator 10 is disposed in the container 1 for agitating the insulating coolant. The high-voltage box 11 is disposed in the container 1 and is relatively isolated from the insulating coolant, and the high-voltage box 11 is electrically connected to the battery cell 2.

[0078] In the above structure, by providing the agitator 10, the coolant in the first accommodating cavity 101 can be agitated, thereby improving the heat exchange effect. The high-voltage box 11 is used for the electrical control of the battery cell 2.

[0079] At the same time, the spatial horizontal flow network with multiple layers of horizontal flow and the vertical flow direction of the coolant formed by the agitator 10 create a spatial flow network, improve the coolant flow, and also improve the convective heat exchange of the coolant at different temperatures in the container 1, control and reduce the temperature difference of the coolant in different regions, and further control and reduce the temperature difference of the battery cells 2 in different spaces, greatly improving the heat dissipation effect of the battery cells 2, ensuring the consistency of the battery cells 2, and improving the battery service life.

[0080] In some embodiments, the temperature of each battery cell 2 is transmitted to the slave BMS in the high-voltage box through a wiring harness. Several slave BMSs calculate the temperature difference of the battery cells 2 in space. The slave BMSs transmit the temperature difference to the master BMS. When the temperature difference reaches a specified value, the master BMS starts the agitator 10. When the temperature difference is lower than the specified temperature difference, the agitator is turned off. The master BMS sets different temperature difference thresholds and controls the agitator at different rotation speeds according to different temperature difference thresholds, thereby controlling the flow rate of the coolant in the coolant tank and further controlling the cooling effect.

[0081] In some embodiments, the agitator 10 is composed of a motor, a controller, wiring harnesses (power wiring harness, communication wiring harness), etc. The agitator 10 is installed at the bottom of the first accommodating cavity 101 through necessary sealing measures and is connected to the master BMS in the high-voltage box through wiring harnesses (power wiring harness, communication wiring harness).

[0082] Specific implementation steps:

[0083] The liquid chiller 5 is used to circulate the coolant in the first accommodating cavity 101, thereby ensuring the flow and cooling effect of the coolant. When the coolant is flowing, the coolant is split by the side splitter 8 and the middle splitter 9 so that the coolant can flow better between the battery packs 100 and in the flow channels 301 of the cooling channel member 3. At the same time, with the agitation of the agitator 10, a good heat dissipation effect can be ensured.

[0084] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
