Therefore, they should not be construed as limitations on this application.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0034] Example 1

[0035] like Figure 1 As shown, a battery thermal management system layout structure for a hybrid loader is disclosed. The battery thermal management system includes a water tank 1 and a thermal management assembly 2 installed above the battery frame. The water tank 1 and the thermal management assembly 2 are connected by a pipeline. A first pipeline 3 is horizontally led out from the outlet of the thermal management assembly 2, and a second pipeline 4 is horizontally led out from the inlet.

[0036] like Figure 3 As shown, the first pipe 3 horizontally passes forward around the right side of the thermal management assembly 2, then horizontally passes the front side of the thermal management assembly 2, and then passes downward through the upper sealing plate of the battery frame at the left front of the thermal management assembly 2, connecting to the main pipe of the first water distributor 8 fixed on the left side of the battery; the first water distributor 8 leads downward to the first branch pipe 14, the second branch pipe 15 and the third branch pipe 16; the first branch pipe 14, the second branch pipe 15 and the third branch pipe 16 successively pass forward horizontally around the battery from the left side of the battery, and then connect to the left water inlet of the upper, middle and lower layers of the battery respectively;

[0037] like Figure 4As shown, the second pipeline 4 horizontally extends from the right side of the thermal management assembly 2, passes through the upper sealing plate of the battery frame from the right front direction of the thermal management assembly 2, and is connected to the main pipe of the second water distributor 20 fixed on the right side of the battery; the second water distributor 20 leads out the fourth branch pipe 17, the fifth branch pipe 18 and the sixth branch pipe 19; the fourth branch pipe 17, the fifth branch pipe 18 and the sixth branch pipe 19 are connected to the right water outlet of the upper layer, the middle layer and the lower layer of the battery in turn after horizontally extending from the right side of the battery and bypassing the back of the battery.

[0038] All pipelines horizontally or vertically pass through the water tank 1 and the thermal management assembly 2, and do not cross between the pipelines.

[0039] The exhaust pipe 6 is led out from the upper right of the water tank 1, and the other end of the exhaust pipe 6 is connected to the first pipeline 3; the water supplement pipe 5 is led out from the lower right of the water tank 1, and the other end of the water supplement pipe 5 is connected to the second pipeline 4.

[0040] The first branch pipe 14, the second branch pipe 15 and the third branch pipe 16 are the water inlet pipes of the battery; the fourth branch pipe 17, the fifth branch pipe 18 and the sixth branch pipe 19 are the water outlet pipes of the battery.

[0041] The exhaust device is used for discharging the gas in each part of the system when the refrigerant is filled for the first time, and the system is filled with the refrigerant through the opening at the top of the water tank 1, so that the air in the system flows to the water tank 1 through the exhaust pipe 6 on the first pipeline 3 and is discharged. The water supplement pipe 5 is convenient for supplementing the cooling liquid in time to maintain the cooling efficiency of the system. The first branch pipe 14, the second branch pipe 15 and the third branch pipe 16 accurately send the cooling liquid to each level of the battery, which ensures the effective cooling of the battery pack. The fourth branch pipe 17, the fifth branch pipe 18 and the sixth branch pipe 19 guide the liquid after heat exchange in the battery, which realizes the effective transfer and utilization of heat. The whole thermal management system has a compact and reasonable arrangement structure, which effectively improves the battery thermal management efficiency of the hybrid loader.

[0042] In the embodiment, the first water distributor 8 and the second water distributor 20 are symmetrically distributed about the battery and are fixed by two parallel small L-shaped fixing members 10.

[0043] Specifically, the long side of the small L-shaped fixing member 10 is fixed on the battery, and the short side of the small L-shaped fixing member 10 is fixed on the upper sealing plate inside the battery frame; the long side is also fixed with an arc-shaped fixing plate 11 for surrounding the main pipes of the first water distributor 8 and the second water distributor 19, and the two sides of the two main pipes are respectively surrounded. Among them, the long side of the small L-shaped fixing member 10, the long side and the arc-shaped fixing plate 11, and the short side and the upper sealing plate are all fixed by bolts.

[0044] The selection of the small L-shaped fixing member 10 not only considers the fixing effect, but also takes into account the space utilization, so that the layout of the entire thermal management system is more compact. The addition of the arc-shaped fixing plate 11 further enhances the stability of the main pipe of the water distributor, preventing displacement during operation due to vibration or external forces. At the same time, the bolted fixing method not only facilitates installation, but also ensures firm connection, ensuring reliable operation of the thermal management system under complex working conditions.

[0045] In this embodiment, the horizontal transverse of the first pipeline 3 passes through the front side part 2, and is fixed by two L-shaped fixing members 9.

[0046] Specifically, the short side of the L-shaped fixing member 9 is fixed to the upper sealing plate outside the battery frame, and the long side of the L-shaped fixing member 9 is fixed with an arc-shaped pipe clamp 12 for surrounding and fixing the first pipeline 3. The long side of the L-shaped fixing member 9 and the arc-shaped pipe clamp 12 are fixed by bolts.

[0047] In this embodiment, all pipeline or branch pipe bends are connected by elbows, which is easy to sub-pack and shortens the installation time in the workshop, facilitating disassembly and assembly.

[0048] An overflow port is installed above the water tank 1, and an overflow pipe 7 is led out from the overflow port. If the liquid in the water tank or other liquid container reaches the set maximum liquid level, the excess liquid is discharged through the overflow pipe to avoid the risk of liquid overflowing the container and causing the surrounding environment to be flooded. In addition, in some closed or semi-closed liquid systems, when the liquid expands due to heating or other reasons, the volume increases and the pressure rises, the overflow pipe can allow excess liquid to flow out, thereby maintaining stable pressure in the system.

[0049] The first pipeline 3 and the second pipeline 4 pass through the upper sealing plate of the battery frame through the plate joint 13 Figure 5 .

[0050] A round hole is provided on the upper sealing plate corresponding to the pipe passing position, and the plate joint 13 is connected to the fixed seat welded on the surface of the upper sealing plate Figure 6 to pass through the plate, and a rubber pad is provided between the fixed seat and the plate joint 13 for waterproof sealing.

[0051] The plate joint has good corrosion resistance and high pressure resistance, ensuring long-term stable operation in the battery thermal management system. In combination with the fixed seat and the sealing of the rubber pad, a reliable waterproof barrier is formed, effectively preventing liquid from leaking into the battery frame and ensuring the safe operation of the battery. In addition, the plate joint also has the characteristics of easy installation and disassembly, which facilitates the replacement or maintenance of the pipeline during the maintenance process of the battery thermal management system.

[0052] In this embodiment, the battery thermal management system adjusts the battery in the following manner:

[0053] The heat regulating mode has two modes of refrigeration and heating, and the waterway takes refrigeration as an example:

[0054] The low-temperature water (high-temperature water when heating) flows out from the water outlet of the heat management assembly 2, flows through the plate joint 13 by the first pipeline 3, flows into the first water distributor 8, and is distributed to the first branch pipe 14, the second branch pipe 15 and the third branch pipe 16. The low-temperature water enters the battery from the battery water inlet, becomes high-temperature water (low-temperature water when heating) after heat exchange in the battery, flows out from the battery water outlet, flows into the second water distributor 20 through the fourth branch pipe 17, the fifth branch pipe 18 and the sixth branch pipe 19, flows through the plate joint 13 and the second pipeline 4 to the water inlet of the heat management assembly 2 and enters the heat management assembly 2, and the high-temperature water becomes low-temperature water (when heating, it is the opposite.) Thus, the refrigeration is formed by circulation.

[0055] Although the specific embodiments of the utility model are described in combination with the drawings, it is not a limitation on the protection scope of the utility model, and those skilled in the art should understand that various modifications or deformations made by those skilled in the art on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
