Description

Technical Field

[0001] The present invention relates to the technical field of cooling devices for electric equipment, and in particular to an assembled mounting structure for automobile batteries. Background Art

[0002] As one of the important components of electric vehicles, automotive batteries are usually installed in a modular manner to facilitate replacement and upgrades. Modular installation usually involves fixing the batteries in a module rack, and then stacking the module racks in battery trays for storage. The stability and safety of the batteries during use are greatly affected by the battery temperature. Existing modular battery packs use thermal pads to maintain the battery's operating environment.

[0003] Existing devices use thermal pads to dissipate heat and integrated water-cooling pipes for cooling. The thermal pads do not provide uniform cooling during high-power charging and discharging, which can easily cause the batteries located in the center to be damaged by high temperatures and accelerate damage. In addition, water cooling is affected by the heat dissipation position, and the temperature of the battery pack at the water-cooling end cannot be effectively reduced. Moreover, the temperature at the center of the stack of multiple batteries cannot be reduced in time, which can easily cause damage to the batteries, reduce the battery life, and affect the operational stability. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem in the prior art that the heat dissipation uniformity of the thermal pad is poor during high-power charging and discharging, which easily causes the high temperature and accelerated damage of the battery in the center position and the poor cooling effect of the water cooling end and the stacking center of the battery. An assembled mounting structure for automotive batteries is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] Preferably, the cooling component includes a cooling groove opened on the outside of the transfer isolation piece, and the cooling groove is arranged in a trapezoidal shape.

[0009] Preferably, the top closure assembly includes an upper cover plate attached to the top of the outer frame, and the surface of the upper cover plate is respectively provided with exhaust and cooling holes, water outlet holes and battery lead holes, the exhaust and cooling holes are coaxial with the battery, the water outlet holes are coaxial with the constant temperature hole, and an extension cavity is provided in the middle of the constant temperature hole, and the extension cavity is coaxial with the wind cavity.

[0010] Preferably, the bottom support assembly includes a bottom support plate attached to the bottom of the outer frame, the surface of the bottom support plate is respectively provided with battery lead holes, water outlet holes and extension cavities, and the top of the upper cover plate and the bottom of the bottom support plate are both provided with circulation components.

[0011] Preferably, the circulation component includes a closing cover that fits tightly against one end of the water outlet, a collar frame is inserted into the inner wall of the closing cover, and a through hole of the collar frame is sleeved on the outside of the epitaxial cavity.

[0012] Preferably, a sealing plug is inserted into the inner wall of the epitaxial cavity located on the surface of the upper cover plate, and the sealing plug is adapted to the epitaxial cavity.

[0013] Preferably, the upper cover plate, the bottom support plate and the outer frame are connected by a locking assembly, and the locking assembly includes a vertical rod fixed to the surface of the bottom support plate, the top end of the vertical rod passes through the outer frame and the upper cover plate in sequence, and is connected to a flange ring through a flange, one end of the enclosing plate is fixed to the inner side wall of the outer frame, and the bottom of the enclosing plate is fixed to the surface of the support plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention sets an outer frame, and the stacked outer frame can cool the battery segment by segment through the oblique slot blowing holes, so as to avoid the situation that the battery in the center position cannot be effectively cooled during high-power charging and discharging, which causes accelerated battery aging and reduced battery operation stability; at the same time, the gas blown out of the oblique slot blowing holes passes through the constant temperature liquid in the constant temperature hole and is discharged after being heated or cooled in winter or summer to cool or heat the battery segment, so that the battery always works in the best working environment, thereby effectively reducing the aging loss of the battery and improving the stability and safety of the battery during operation.

The enclosure plate can isolate multiple battery cooling rings separately, promoting uniform heat dissipation on the battery surface located in the middle position of the support plate.

[0028] Example, see Figures 1 to 6, an assembled mounting structure for a car battery, comprising a battery 1 arranged in an assembled mounting assembly, the assembled mounting assembly comprising an outer frame 2, a support plate 3 fixed to the inner middle part of the outer frame 2, a battery cooling ring 4 fixed to the upper surface of the support plate 3, a damping support plate 5 fixed to the inner wall of the battery cooling ring 4, and an inclined slot blowing hole 6 is also opened on the inner wall of the battery cooling ring 4, an inclined slot is opened on the side of the damping support plate 5, and the upper and lower inclined slots can form a converging channel 24, a plurality of damping support plates 5 and inclined slot blowing holes 6 are alternately arranged, the damping support plate 5 is located at the upper and lower ends of the inner wall of the battery cooling ring 4, and the support plate 3 is fixed to the upper and lower ends of the inner wall of the battery cooling ring 4. A constant temperature hole 7 is provided in the middle, an air cavity 8 is provided in the middle of the constant temperature hole 7, a dispersion hole 9 is provided on the outside of the air cavity 8, a transfer isolation plate 10 is fixed on the outside of the dispersion hole 9, an enclosure plate 25 is fixed at one end of the transfer isolation plate 10, one end of the enclosure plate 25 is fixed to the inner wall of the outer frame 2, and the bottom of the enclosure plate 25 is fixed to the surface of the support plate 3. A through cavity 11 is provided in the middle of the transfer isolation plate 10, and the dispersion hole 9 is communicated with the through cavity 11. A cooling component is provided on the outside of the transfer isolation plate 10. Furthermore, the cooling component includes a cooling groove 12 provided on the outside of the transfer isolation plate 10, and the cooling groove 12 is arranged in a trapezoidal shape.

[0029] The further benefit of adopting the above method is that the cooling groove 12 can increase the contact area between the transfer isolation plate 10 and the air, and the air blown out from the through cavity 11 of the wind cavity 8 in combination with the constant temperature liquid in the constant temperature hole 7 can cool or heat the air, thereby ensuring that each position of the battery 1 is always in a good working temperature environment. The various structural parts in the outer frame 2 are all metal forgings, and their function is to improve the cooling and heating efficiency of the battery 1 under the joint action of the constant temperature liquid in the constant temperature hole 7 and the air in the wind cavity 8. The dispersion holes 9 on the wind cavity 8 can ensure that the gas blown out from each section of the battery 1 is effective cooling or heating gas, and the inclined slot blowing hole 6 is set at an angle, which can make the air blown to the surface of the battery 1 The gas flows around the battery 1 to a certain extent to ensure that each section and each position of the battery 1 can be effectively cooled or heated. The gas blown out of the cavity 11 is blown into the interior of the battery cooling ring 4 through the inclined slot blowing hole 6. The inclined surface of the inclined slot blowing hole 6 can cause the gas to form an oblique flow, and then it is guided by the large-diameter end of the converging channel 24 to form a circulation on the surface of the battery 1, so as to facilitate uniform heat dissipation on the surface of the battery 1.

A collar 20 is inserted into the inner wall of the closed cover 19, and the through-hole of the collar 20 is sleeved onto the outer side of the extension cavity 16. A further advantage of this arrangement is that the closed cover 19 is connected to the thermostatic hole 7, enabling the thermostatic liquid to circulate within the thermostatic hole 7 through the temperature control system, thereby cooling or heating the gas flowing out of the air cavity 8.

[0035] The upper cover plate 13, the bottom support plate 17 and the outer frame 2 are connected by a locking assembly, and the locking assembly includes a vertical rod 22 fixed to the surface of the bottom support plate 17. The top end of the vertical rod 22 passes through the outer frame 2 and the upper cover plate 13 in sequence, and is connected to a flange ring 23 through a flange.

[0036] The battery 1 can be fixed in the upper cover plate 13 , the bottom support plate 17 and the outer frame 2 by means of the flange ring 23 and the vertical rod 22 .

[0037] When the present invention is in use, the closed cover 19 connected to the bottom support plate 17 is the constant temperature liquid inlet section. The constant temperature liquid flows in from here, passes through the constant temperature hole 7, and then flows out from one end of the closed cover 19 connected to the upper cover 13. The upper and lower ports of the closed cover 19 are connected through the temperature control circulation system.

[0038] The epitaxial cavity 16 connected to the bottom support plate 17 is connected to the air pump of the temperature control circulation system through a pipeline, which continuously provides cooling or heating gas to the wind cavity 8;

[0039] The gas in the air cavity 8 flows out from the dispersion hole 9 and is blown out through the through cavity 11 of the transfer isolation plate 10. During the blowing process, the transfer isolation plate 10 at one end of the constant temperature hole 7 can be cooled or heated by the constant temperature liquid.

[0040] The gas blown into the outer frame 2 is blown out through the inclined slot blowing holes 6, forming an annular airflow on the surface of the battery 1 to cool the battery 1.
