firstly, fixedly connecting the mounting plate (2) in a new energy battery box by using bolts, when the module battery is used, supplying pressure to a pressure division pipe (102) in a fixed box (10) by a variable-frequency booster pump (9), increasing the pressure in the pressure division pipe (102), boosting the pressure of the pressure division pipe (102) in a plurality of connecting water pipes (103), enabling cooling liquid filled in a boosting bag (104) and part of the cooling liquid filled in a frame-shaped hollow water channel (8) to move upwards, enabling the cooling liquid to flow upwards from a second cooling liquid channel (11) and the frame-shaped hollow water channel (8) and simultaneously flow upwards from a first cooling liquid channel (12) and a second cooling liquid channel (11) and to be gathered in a convection mode above the module battery, enabling the cooling liquid to enter each single battery (6) in the module battery from the upper part, and enabling the single battery (6) in each module battery to be cooled, a plate-type water cooling jacket (7) is arranged between two adjacent single-chip batteries (6), so that the phenomenon that the temperatures of the two adjacent single-chip batteries (6) are mutually interfered can be avoided, the safety and the stability of the single-chip batteries (6) can be further improved, and the problem of mutual interference does not exist even if the single-chip batteries (6) have abnormal temperatures;

secondly, when cooling water enters the single-chip battery (6), the cooling water firstly enters the isolating and radiating box (61) from the pressure-supply type water inlet resetting mechanism and is respectively shunted at the outer sides of the two battery clamping plates (62) and flows through the surface of the single-chip battery (63), the cooling water under strong pressure can quickly take away heat generated on the single-chip battery (63), the operation of quick radiation is carried out, the single-chip battery (63) is ensured to be at a stable working temperature, the flow is gathered at the position of the cooling liquid pressure adjusting start-stop switch, when the cooling liquid above the pressure adjusting start-stop switch reaches the specified weight, and under the pressurizing condition, the pressure adjusting start-stop switch is opened, the cooling liquid in the single-chip battery (6) is quickly circulated, the internal heat can be quickly treated, the radiating efficiency of the single-chip battery (6) is increased, and the safety of the whole structure can be increased, the service life of the battery is ensured;

a third step; when the water pressure of the cooling water is increased, the sealing plate (645) is subjected to the action of the water pressure, and the sealing plate (645) moves downwards, so that the overlapping state is separated between the sealing plate (645) and the bottom of the elastic plate (644), the cooling liquid is released from a release space between the sealing plate (645) and the bottom of the elastic plate (644), and the cooling liquid can be uniformly distributed on the outer sides of the two battery clamping plates (62);

the fourth step; the cooling liquid gathers at the pressure regulating on-off switch, the water flow gathers in the water collecting sleeve (67), thus make the water level in the water collecting sleeve (67) rise, the cooling liquid above the water collecting sleeve (67) can increase the time staying in the single-chip battery (6) fully, and a part of cooling liquid in the water collecting sleeve (67) flows down in the drain funnel (68), the cooling liquid gathers between two side wing plates (616) and two water blocking cloths (615), make two side wing plates (616) and two water blocking cloths (615) fill up the cooling liquid, thus in the weight of the cooling liquid, two side wing plates (616) drive the riser (613) to move downward, at this moment, after the riser (613) sinks on the triangle strip, release the space of flow between riser (613) and two sealing strips (612), thus when the cooling liquid passes through this space, the cooling liquid finishes the primary circulation, when the circulating cooling liquid enters the hollow water (8) of the frame type, the cooling liquid with the increased temperature is subjected to secondary circulation after being subjected to heat dissipation and cooling in the frame-type hollow water route device (8), so that the heat exchange time of the cooling liquid can be prolonged, and the high temperature generated by the single module battery (63) can be quickly dissipated;
