The three-dimensional arrangement facilitates subsequent maintenance by operators. A water cooling device 4 is provided at the top of the frame 2. Water inlet transition pipes 5 are vertically fixed on both sides of the frame 2. The water cooling device 4 is respectively connected to the water inlet transition pipes 5 through water distribution pipes 7.

Return water transition pipes 6 are fixed on both sides of the frame 2. The return water transition pipes 6 are all connected to the water outlets of the storage battery 3 cooling pipes. The two return water transition pipes 6 are connected to the water cooling device 4 through water distribution pipes 7;

[0026] The water inlet transition pipe 5 includes a first pipe body 51. The first pipe body 51 is vertically arranged. The vertical arrangement avoids bubbles from circulating in the cooling pipeline. A first water inlet 52 is provided on the upper side of the first pipe body 51. A number of first water outlets 53 are provided on the side surface of the first pipe body 51. The first water outlets 53 are arranged below the first water inlet 52. The first water inlet 52 is arranged at the uppermost end of the first pipe body 51 to avoid bubbles from entering the pipeline circulation.

[0027] The return water transition pipe 6 includes a second pipe body 61 which is vertically arranged. The vertical arrangement prevents air bubbles from circulating in the cooling pipeline. An air outlet 64 is provided at the top of the second pipe body 61. A second water outlet 62 is provided on the side of the second pipe body 61 and is arranged below the air outlet 64. A plurality of second water inlets 63 are provided on the side of the second pipe body 61 and are all arranged below the second water outlet 62. The second water outlet 62 is arranged at the uppermost end of the second pipe body 61, where the air bubbles float to the topmost point, preventing the air bubbles from entering the pipeline circulation.

[0028] Specifically, the first water inlet 52 is communicated with the corresponding water distribution pipe 7 through a pipeline, and a plurality of first water outlets 53 are respectively communicated with the water inlets of the corresponding battery 3 cooling pipes.

[0029] Specifically, the air outlet 64 is communicated with the water cooling device 4 through a pipeline. A plurality of second water inlets 63 are respectively communicated with the water outlets of the corresponding battery 3 cooling pipes, and the second water outlet 62 is connected with the corresponding water distribution pipe 7 through a pipeline.

[0030] Specifically, the water distribution pipe 7 is fixedly connected to the frame 2 through a pipe support 9.

[0035] Specifically, the water inlet transition pipe 5 and the water outlet transition pipe are both arranged close to the middle of the frame 2, which is convenient for maintenance.

[0036] The principle of the present utility model is that the coolant in the water cooling device 4 enters the water distribution pipe 7, and is split by the water distribution pipe 7 and enters the water inlet transition pipes 5 on both sides respectively. The water inlet transition pipes 5 are vertically arranged and the first water inlet 52 is at the uppermost position. The coolant entering the water inlet transition pipe 5 through the first water inlet pipe is split through the first water outlet 53 and enters the cooling pipes of each storage battery 3. When the coolant enters the water inlet transition pipe 5, air bubbles will reach the uppermost end of the water inlet transition pipe 5 due to buoyancy and will not enter the cooling pipes. The number of air bubbles generated at this stage is small. After the coolant enters the storage battery 3 for heat exchange to cool the storage battery 3, it flows back to the water return transition pipe 6 through the pipeline, and then returns to the water cooling device 4 through the second water outlet 62 for circulation. The air bubbles rise to the highest end of the water return transition pipe 6 due to buoyancy and are regularly discharged through the air outlet 64. After being discharged from the air outlet 64, they re-enter the water cooling device 4 to condense and return the coolant.

[0037] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
