Description

Technical Field

[0001] The present invention relates to the technical field of energy storage batteries, and in particular to an energy storage battery pack capable of improving heat dissipation effect. Background Art

[0002] An energy storage battery pack refers to a number of energy storage batteries connected together to provide more powerful power. The connection methods of the energy storage batteries in the energy storage battery pack are divided into series and parallel. The parallel connection requires that the voltage of the energy storage batteries is the same. The energy storage battery pack using parallel connection can provide a larger current.

[0003] When the energy storage battery pack is charging or discharging, a large amount of heat is generated. Coupled with the influence of the close arrangement of the battery space, the temperature inside the energy storage battery pack will rise rapidly. Even if the temperature inside the energy storage battery pack can be effectively reduced by the existing heat dissipation device, the local heat in the box is difficult to discharge evenly, and there are large differences in the operating environment of the energy storage battery. The long-term operation of the energy storage battery pack in an environment with a large temperature difference will lead to serious differences in the internal resistance and capacity between the batteries, which may cause some batteries to be overcharged or over-discharged, affecting the performance and life of the energy storage battery pack, and even causing serious safety hazards.

[0004] In the prior art, the heat dissipation method inside the energy storage battery pack is mostly air cooling, and air cooling is mainly achieved by air supply components such as heat dissipation fans. However, the remaining space inside the energy storage battery pack is limited, and it is difficult to install a large fan. The only alternative is to use a porous air duct to supply air. However, the position of the air duct is relatively fixed. When the air is supplied by the air duct, the wind direction, wind speed and other parameters of the cold air are difficult to adjust, resulting in uneven air supply and affecting the air cooling effect.

The limiting shaft 16 rotates, driving the limiting bevel gear 17 to rotate, thereby driving the linkage bevel gear 15 to rotate, and then driving the second linkage shaft 14 to rotate, and then driving a group of movable shafts 12 to rotate.

[0049] See also Figure 2 - Fig. 9 An installation box 21 is installed inside the energy storage battery pack body 1, and liquid collecting boxes 22 are installed on both sides of the installation box 21. The two groups of liquid collecting boxes 22 are made of rubber material. Push plates 23 are installed at one end of the two groups of liquid collecting boxes, and the inner walls of the two ends of the two groups of push plates 23 are respectively threadedly connected with the outer walls of multiple groups of third linkage shafts 24. The multiple groups of third linkage shafts 24 rotate to drive the two groups of push plates 23 to move back and forth, thereby driving the two groups of liquid collecting boxes 22 to deform.

[0050] See also Figure 2 - Fig. 9 Coolant is provided inside the installation box 21 and the two sets of liquid collecting boxes 22. A liquid outlet pipe 27 and a liquid inlet pipe 31 are respectively installed at both ends of the installation box 21. A one-way valve is installed inside the liquid outlet pipe 27, and a one-way valve with an opposite effect to the one-way valve inside the liquid outlet pipe 27 is installed inside the liquid inlet pipe 31. The two sets of liquid collecting boxes 22 are deformed, squeezing the coolant, so that the coolant is discharged through the liquid outlet pipe 27 and refluxes through the liquid inlet pipe 31.

[0051] See also Figure 2 - Figure 8 A liquid distributor 28 is installed at the upper end of the liquid outlet pipe 27, and the outer walls of the multiple groups of cooling plates 8 are provided with reserved grooves 9. The inner walls of the multiple groups of reserved grooves 9 are installed with cooling pipes 29, and one end of the multiple groups of cooling pipes 29 is connected to the liquid distributor 27. After the coolant enters the liquid outlet pipe 27, the coolant flows into the liquid distributor 28, and the coolant is diverted to the multiple groups of cooling pipes 29 through the liquid distributor 28.

[0052] See also Figure 2 - Figure 8 A collecting pipe 30 is installed at one end of the liquid inlet pipe 31, and the collecting pipe 30 is connected to one end of the multiple groups of cooling pipes 29. The liquid inlet pipe 31 generates negative pressure, and the coolant inside the multiple groups of cooling pipes 29 is introduced into the collecting pipe 30, and refluxes to the installation box 21 and the two groups of collecting boxes 22 through the liquid inlet pipe 31.

[0053] See also Figure 2 - Figure 8 The cross-sections of the multiple groups of reserved grooves 9 and the multiple groups of cooling pipes 29 are all "S"-shaped, and the outer walls of the multiple groups of cooling pipes 29 are connected to the outer walls of the multiple groups of energy storage battery bodies 32 to increase the contact area between the cooling pipes 29 and the energy storage battery bodies 32, thereby improving the heat absorption effect of the cooling pipes 29.

[0054] See also Figure 1 , filters are installed at the upper ends of the two groups of air inlets 2, and filter plates are installed at one end of the two groups of air outlets 3. The setting of the filters and the filter plates prevents floating dust particles from entering the energy storage battery pack body 1 through the air inlet 2 or the air outlet 3, thereby affecting the heat dissipation effect.

[0055] The working principle of the present invention is as follows: when the energy storage battery pack body 1 is in use, the driving motor 18 is started, driving the driving shaft 19 to rotate, thereby driving the driving bevel gear 20 to rotate, and the driving bevel gear 20 is meshed and connected with the transmission bevel gear 26, so the transmission bevel gear 26 rotates, thereby driving the transmission shaft 25 to rotate, the transmission shaft 25 is connected to a group of first linkage shafts 4 through a synchronous belt, so a group of first linkage shafts 4 rotates, and two groups of first linkage shafts 4 are connected through a synchronous belt, so the two groups of first linkage shafts 4 rotate synchronously, thereby driving the two groups of first fans 5 to rotate;

[0056] When the two groups of first fans 5 rotate, airflow is driven to enter from the two groups of air inlets 2, and the filter plate arranged at the upper end of the air inlet 2 blocks the dust particles in the air, and the airflow enters the two groups of air collecting pipes 6 through the two groups of air collecting pipes 6, and enters the air collecting plate 7 through the two groups of air collecting pipes 6, and then enters the multiple groups of cooling plates 8 through the air collecting plate 7. The multiple groups of cooling plates 8 are attached to the outer walls of the multiple groups of energy storage battery bodies 32, and absorb heat from the multiple groups of energy storage battery bodies 32. The airflow enters the multiple groups of cooling plates 8 and absorbs the heat absorbed by the multiple groups of cooling plates 8;

[0057] When the driving shaft 19 rotates, the driving shaft 19 is connected to two groups of third linkage shafts 24 through synchronous belts, the two groups of third linkage shafts 24 rotate, and one group of third linkage shafts 23 is connected to the limiting shaft 16 through a synchronous belt, so the limiting shaft 16 rotates, thereby driving the limiting bevel gear 17 to rotate, and the limiting bevel gear 17 is meshed and connected with the linkage bevel gear 15, so the linkage bevel gear 15 rotates, thereby driving the second linkage shaft 14 to rotate, and then driving a group of movable shafts 12 to rotate, and multiple groups of movable shafts 12 are connected through synchronous belts, so multiple groups of linkage shafts 12 rotate synchronously, thereby driving multiple groups of second fans 13 to rotate;

[0058] When the multiple sets of second fans 13 rotate, the internal airflow of the multiple sets of cooling plates 8 is guided to the air outlet plate 11 through the connecting pipe 10, and the airflow is conducted to the air outlet 3 through the two ends of the air outlet plate 11 for discharge, which further accelerates the flow of airflow inside the cooling plates 8. In addition, the arrangement of the multiple sets of second fans 13 avoids the situation where the airflow inside some cooling plates 8 is too small, so that the airflow enters the multiple sets of cooling plates 8 more evenly, thereby improving the heat dissipation effect of the energy storage battery body 32.

[0059] When the two sets of third linkage shafts 24 rotate, the multiple sets of third linkage shafts 24 are connected by synchronous belts, so the multiple sets of third linkage shafts 24 rotate, and the inner walls at both ends of the two sets of push plates 23 are respectively threadedly connected with the outer walls of the multiple sets of third linkage shafts 24, so the two sets of push plates 23 move back and forth;

[0060] When the two push plates 23 push one end of the two liquid collecting boxes 22 to move toward the installation box 21, the coolant in the two liquid collecting boxes 22 is pushed out through the liquid outlet pipe 27, and the one-way valve inside the liquid inlet pipe 31 is set, so that the coolant is not discharged from the liquid inlet pipe 31;

[0061] After the coolant enters the liquid outlet pipe 27, the coolant flows into the liquid distributor 28, and is distributed to the multiple cooling tubes 29 through the liquid distributor 28. The multiple cooling tubes 29 are respectively attached to the outer walls of the multiple energy storage battery bodies 32 and the inner walls of the multiple reserved grooves 9, so as to further absorb the heat generated by the multiple energy storage battery bodies 32, thereby improving the heat dissipation effect of the multiple energy storage battery bodies 32.

[0062] When the two groups of push plates 23 drive the two groups of liquid collecting boxes 22 to move toward the two ends of the energy storage battery column body 1 respectively, the liquid inlet pipe 31 generates negative pressure, and the coolant inside the multiple groups of cooling pipes 29 is introduced into the liquid collecting pipe 30, and flows back to the installation box 21 and the two groups of liquid collecting boxes 22 through the liquid inlet pipe 31. The setting of the one-way valve inside the liquid outlet pipe 27 makes the coolant reflux not pass through the liquid outlet pipe 27, so that the coolant is reciprocated and circulated, further improving the heat dissipation effect inside the energy storage battery group body 1 while reducing the loss of coolant;

[0063] The present invention is provided with an air collecting plate 7, a cooling plate 8 and an air outlet plate 11. The airflow enters the air collecting plate 7 and enters the multiple cooling plates 8 through the air collecting plate 7. The multiple cooling plates 8 are attached to the outer walls of the multiple energy storage battery bodies 32 to absorb heat from the multiple energy storage battery bodies 32. The airflow enters the multiple cooling plates 8 to absorb the heat absorbed by the multiple cooling plates 8 and conducts the airflow to the air outlet 3 through the two ends of the air outlet plate 11 for discharge, thereby improving the heat dissipation effect inside the energy storage battery body 1.
