The suction holes (21) are connected to the second flow channel. The suction holes (21) are used to actively suction the immersion liquid.

2. The side-suction immersed cooling structure of claim 1, wherein: Multiple protrusions (24) are provided on both sides of the upright plate (2), and the protrusions (24) are used to increase the gap between the battery cell (3) and the upright plate (2).

3. The side-suction immersed cooling structure of claim 2, wherein: The protrusion (24) is strip-shaped and is perpendicular to the base plate (1).

4. The side-suction immersed cooling structure of claim 2, wherein: The protrusion (24) is used for soft contact with the battery cell (3).

5. The side-suction immersed cooling structure of claim 1, wherein: The suction holes (21) are provided in multiple groups, and the multiple suction holes (21) in each group of suction holes (21) are arranged in a plum blossom shape.

6. A battery pack, characterized by: The side-suction immersion cooling structure according to any one of claims 1 to 5 further includes a housing and a plurality of battery cells (3), wherein an immersion liquid is provided in the housing, and both the side-suction immersion cooling structure and the battery cells (3) are installed in the housing, and the battery cells (3) are fixed between two adjacent upright plates (2).

7. The battery pack of claim 6, wherein: The top of the upright plate (2) is provided with a CTP pressure strip fixing hole (22), and a CTP fixing strip (23) is inserted through the CTP pressure strip fixing hole (22). The battery cell (3) is pressed onto the bottom plate (1) by the CTP fixing strip (23), and the CTP fixing strip (23) is detachably and fixedly connected to the housing.

8. The battery pack of claim 7, wherein: The CTP fixing strip (23) has screw holes at both ends, and the CTP fixing strip (23) is detachably fixed to the box body by a long screw.

9. The battery pack of claim 6, wherein: End plates are provided at both ends of the side-suction immersion cooling structure. Steel strips are provided on the end plates. The steel strips fix the battery cells (3) on the side-suction immersion cooling structure to the upright plate (2) through the two end plates.

10. The battery pack of any one of claims 6-9, wherein: The bottom plate (1) is provided with a liquid inlet (11) and a third flow channel is provided on the bottom plate (1).
