[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a battery thermal management device with a rapid cooling structure, such as... Figure 1 and Figure 2 As shown, the battery thermal management storage structure 1 includes a battery thermal management housing 11. A top cover 12 is detachably installed on the upper side of the battery thermal management housing 11. A shock-absorbing component 13 is installed on the lower side of the battery thermal management housing 11 and plays an auxiliary role in shock absorption. The shock-absorbing component 13 includes a support rod 131. A shock-absorbing pad 132 is installed on the lower side of the support rod 131. A base 133 is installed on the lower side of the shock-absorbing pad 132.

[0025] Among them, the battery thermal management housing 11 is equipped with a control device for controlling the overall equipment;

[0026] Specifically, the battery thermal management housing 11 has an exhaust vent on the lower side. There are two sets of exhaust vents, and filter screens are installed in the two sets of exhaust vents, so as to play the role of exhausting air and preventing mosquitoes.

[0027] Furthermore, the battery thermal management housing 11 is disassembled and installed on the top cover 12 by bolts, which facilitates the maintenance and treatment of the internal power battery in the future.

[0028] In the above scheme, the top cover 12 is placed on the battery thermal management housing 11, and the bolts are passed through the battery thermal management housing 11 and the top cover 12, so as to facilitate the sealing of the battery thermal management housing 11. With the assistance of the shock-absorbing pad 132 between the support rod 131 and the base 133, it plays an auxiliary role in shock absorption.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the battery thermal management storage structure 1 is connected to a rapid cooling structure 2 at both its left and right ends for rapid cooling of the battery thermal management storage structure 1. The rapid cooling structure 2 includes a first air inlet pipe 21. A first baffle 22 is welded to the end of the first air inlet pipe 21 away from the battery thermal management housing 11. A motor drives a first sealing assembly 23 to rotate on the first baffle 22. A uniform air distribution plate 24 is provided on the right side of the first sealing assembly 23. The uniform air distribution plate 24 is installed inside the first air inlet pipe 21. A cooling fan 25 is installed on the uniform air distribution plate 24 to assist in heat dissipation. An air inlet is provided at the connection between the first air inlet pipe 21 and the battery thermal management housing 11. 27, thereby ensuring that the heat dissipation air enters the battery thermal management housing 11 for heat dissipation treatment. The water cooling component 28 is embedded in the battery thermal management housing 11 and the top cover 12 and is used for water cooling heat dissipation. A heat conduction plate 29 is provided in the space enclosed by the water cooling component 28. The first sealing component 23 includes a rotating plate 231. Air inlets 232 are opened on both the rotating plate 231 and the first baffle 22. A first filter screen 233 is installed in the air inlets 232 on the rotating plate 231 and is used to filter impurities. The water cooling component 28 includes a water cooling pipe 281. One end of the water cooling pipe 281 is connected to the water inlet 282, and the other end of the water cooling pipe 281 is connected to the water outlet 283.

[0030] Among them, there are two sets of first air intake pipes 21, and the two sets of first air intake pipes 21 are symmetrically arranged about the central axis of the battery thermal management shell 11;

[0031] A humidity sensor is installed inside the first air intake pipe 21, and a temperature sensor is installed inside the battery thermal management housing 11. The temperature sensor is model CWDZ11 and the humidity sensor is model DHT11. The temperature sensor and humidity sensor transmit the detected data to the processor, and the information processed by the processor is transmitted to the control device. The control device adjusts other electrical components such as the cooling fan 25, heater 26, and small dehumidifier 32 according to the humidity and temperature data.

[0032] Specifically, multiple sets of air inlets 232 are penetrated on both the first baffle 22 and the rotating plate 231. The multiple sets of air inlets 232 are distributed at equal intervals on the first baffle 22 and the rotating plate 231. The number and inner diameter of the air inlets 232 opened on the first baffle 22 and the rotating plate 231 are the same.

[0033] The motor fixed on the first baffle 22 is a small stepper motor, which is existing technology;

[0034] Furthermore, the water-cooling pipe 281 is embedded in the battery thermal management housing 11 and the top cover 12 in a serpentine shape, thereby better playing the role of water cooling.

[0035] In the above scheme, heat conduction is performed with the assistance of heat-conducting plate 29. The stepper motor on the air distribution plate 24 inside the first air intake pipe 21 drives the cooling fan 25 to rotate. As the cooling fan 25 rotates, natural air passes through the air intake holes 232 on the rotating plate 231 and the first baffle 22, and is filtered through the first filter screen 233. The filtered air enters the air inlet 27 on the first air intake pipe 21, finally cooling the battery inside the battery thermal management casing 11. If the battery pack remains at a high temperature, cooling liquid enters the water cooling pipe 281 through the water inlet 282. The water cooling pipe 281 conducts heat within the battery thermal management casing 11, and the heat-absorbing liquid is discharged through the water outlet 283. With the assistance of the heat-conducting plate 29, water-cooling pipe 281, and cooling fan 25, the battery is quickly cooled down, thus preventing it from being in a high-temperature environment for a long time and affecting its service life. If the humidity sensor installed in the first air intake pipe 21 detects that the internal humidity is too high or when the battery is not in use, the stepper motor on the first baffle 22 is rotated. The stepper motor drives the rotating plate 231 to rotate, so that the air intake hole 232 on the rotating plate 231 rotates to the unopened position of the first baffle 22, thereby assisting in the sealing function and increasing practicality. If it is necessary to heat up the air entering the battery thermal management shell 11, the control device starts the heater 26. With the assistance of the heater 26, the air is heated up, thus preventing the temperature from being too low and affecting the battery's service life.

[0036] like Figure 2 and Figure 4 As shown, the rapid cooling structure 2 is connected to the auxiliary dehumidification component 3 on the lower side and is used for auxiliary dehumidification. The auxiliary dehumidification component 3 includes a second air inlet pipe 31, which is connected to a small dehumidifier 32 and is used for dehumidification. The small dehumidifier 32 is connected to a third air inlet pipe 33. A second sealing component 34 is installed on the third air inlet pipe 33, and an air intake fan 35 is installed inside the second air inlet pipe 31.

[0037] The second sealing component 34 and the first sealing component 23 have the same structure, so as to seal the third air intake pipe 33 when not in use;

[0038] Specifically, the small dehumidifier 32 is existing technology. A moisture-absorbing net is provided at the connection between the second air inlet pipe 31 and the small dehumidifier 32, so as to further process the air after it has been processed by the small dehumidifier 32, thereby improving the moisture absorption effect.

[0039] The small dehumidifier 32 can be disassembled and installed with the second air inlet pipe 31 and the third air inlet pipe 33, which facilitates the later maintenance of the small dehumidifier 32 and the replacement of the dehumidifying screen. A sealing ring is provided between the small dehumidifier 32 and the second air inlet pipe 31 and the third air inlet pipe 33 to prevent air leakage.

[0040] In the above scheme, when the external air humidity is high, the second sealing component 34 is opened, and the air enters the small dehumidifier 32 for dehumidification. The treated air is then treated again through the dehumidifying net to improve the dehumidification effect. With the assistance of the fan 35 in the second air inlet pipe 31, the airflow is accelerated to the first air inlet pipe 21.

[0041] Working principle: When using this battery thermal management device with a rapid cooling structure, the external power supply is turned on. The battery thermal management storage structure 1 acts as a shock absorber for the battery. The rapid cooling structure 2 quickly cools the battery inside the battery thermal management storage structure 1. The auxiliary dehumidification component 3 dehumidifies the air entering the battery thermal management housing 11.
