Description
Technical Field
[0001] This utility model relates to the field of battery heat sink technology, specifically to a new energy battery heat sink. Background Technology
[0002] New energy batteries are components that provide electrical energy for new energy vehicles. They are environmentally friendly, producing little or no greenhouse gas emissions during use, which, in contrast to traditional fuels, can effectively improve air quality.
[0003] New energy batteries tend to generate heat during operation. Existing heat dissipation devices are generally installed on the battery, such as using a fan to blow air onto the battery or using water cooling circulation. These types of heat dissipation devices provide a relatively constant amount of heat to the new energy battery. As the vehicle speed changes, the discharge current of the new energy battery also changes, and the heat generated also changes accordingly. A constant amount of heat dissipation is insufficient to meet the needs of heat variation, thus affecting the heat dissipation effect. Utility Model Content

[0037] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0038] like Figures 1-5As shown, this embodiment proposes a new energy battery heat sink, applied to the battery body 1, including: a protective frame 2, heat-conducting plates 3, a passive heat dissipation mechanism, an active heat dissipation mechanism, and an air guide mechanism. The battery body 1 is installed inside the protective frame 2, and thermal grease is applied between the protective frame 2 and the battery body 1. Multiple heat-conducting plates 3 are provided, and multiple heat-conducting plates 3 are fixedly connected to the upper and lower sides of the protective frame 2. Through the cooperation between the protective frame 2, heat-conducting plates 3, passive heat dissipation mechanism, active heat dissipation mechanism, and air guide mechanism, the heat dissipation requirements of the battery body 1 can be adjusted according to the driving speed of the vehicle, thereby improving the heat dissipation effect of the battery body 1.
[0039] The passive heat dissipation mechanism is installed on the protective frame 2 and is used to deliver the airflow generated when the car is running to the space between multiple heat-conducting plates 3. The passive heat dissipation mechanism includes an air inlet box 4 and an air inlet pipe 5. The air inlet box 4 is connected to one side of the protective frame 2. Multiple air inlet pipes 5 are fixedly connected to both the upper and lower sides of the protective frame 2, and one end of each of the multiple air inlet pipes 5 is connected to the air inlet box 4. The output ends of the multiple air inlet pipes 5 are respectively directed towards the space between each pair of adjacent heat-conducting plates 3. Specifically, during the car's operation, the air outside the car enters the air inlet pipe 5 through the air inlet box 4, and then blows the air between the multiple heat-conducting plates 3 through the air inlet pipe 5. The heat on the battery body 1 is transferred to the protective frame 2 through the thermal grease, and the heat is dissipated by blowing air.
[0040] The active cooling mechanism is mounted on the passive cooling mechanism and is used to actively cool the battery body 1 when the vehicle is stopped. The active cooling mechanism includes a rotating plate 6, a fan 7, and a rotating assembly. The rotating plate 6 is rotatably connected inside the air inlet box 4. Multiple fans 7 are provided and are all mounted on the rotating plate 6. When the air inlet box 4 is not receiving air, the rotating plate 6 faces multiple air inlet pipes 5, and the output ends of the multiple fans 7 face multiple air inlet pipes 5. When the air inlet box 4 receives air, the rotating plate 6 is sideways to the multiple air inlet pipes 5 to receive air from the air inlet box 4. The rotating assembly is mounted on the air inlet box 4 and is used to drive the rotating plate 6 to rotate. The rotating assembly includes a rotating gear 9, a motor 10, and a drive gear. 11. A shaft 14 is fixedly connected to the rotating gear 9. The shaft 14 extends through the side wall of the air inlet box 4 and into the air inlet box 4. The shaft 14 is fixedly connected to the rotating plate 6. The motor 10 is installed on the air inlet box 4. The drive gear 11 is fixedly connected to the output end of the motor 10 and meshes with the rotating gear 9. Specifically, when air enters the air inlet box 4, the fan 7 installed on the rotating plate 6 blows the airflow into the air intake pipe and between the two heat conduction plates 3. When the vehicle travels at a high speed, the motor 10 drives the drive gear 11 and the rotating gear 9 to rotate, so that the rotating plate 6 is turned horizontally in the air inlet box 4, thus not affecting the air delivery of the air inlet box 4.
[0041] The system includes two air guides 7, both of which are housed within the protective frame 2, allowing the air to directly contact the battery body 1 for cooling. The air guide mechanism includes air guide pipes 12 and guide plates 13. Multiple guide plates 13 are fixedly connected at an angle within the protective frame 2. There are two air guide pipes 12, which are respectively connected to two air inlet pipes 5 located on the outer side and on the same side. There are multiple guide plates 13, which are fixedly connected within the protective frame 2. The air outlets of the two air guide pipes 12 are directed towards a guide plate 13 that is close to the two air guide pipes 12. Specifically, when the air inlet pipe 5 blows air, a portion of the airflow is diverted through the guide pipe and blown onto the guide plate 13, thereby guiding the airflow to the battery body 1 through the guide plate 13, thus blowing air onto the battery body 1.
[0042] In this embodiment, when the car is traveling at a high speed, the motor 10 drives the drive gear 11 and the rotating gear 9 to rotate, causing the rotating plate 6 to be horizontal inside the air inlet box 4. This does not affect the air delivery of the air inlet box 4, resulting in a stronger airflow entering the air inlet box 4. The strong airflow is blown between the two heat-conducting plates 3 through the air inlet pipe 5. During the blowing process, the strong airflow can carry the airflow between the two heat-conducting plates 3 for heat dissipation. When the car is traveling at a low speed or is stopped, the motor 10 drives the drive gear 11 and the rotating gear 9 to rotate, causing the rotating plate 6 to be vertical. The fan 7 blows air into the air inlet box 4 and the air inlet pipe 5, strengthening the airflow of the air inlet pipe 5 and improving the heat dissipation effect.
[0043] It should also be added that the faster the car travels, the greater the air intake, and the better the heat dissipation effect.
[0044] It should also be noted that motor 10 is a reversible motor, capable of driving drive gear 11 to rotate forward and backward.
[0045] In addition, to improve heat dissipation, a commercially available cooler can be installed inside the air intake box 4 to dissipate cool air, thereby improving the heat dissipation effect.
[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
