Description
Technical Field
[0001] The utility model relates to the technical field of battery box air cooling, in particular to a novel battery box air cooling system. Background Art
[0002] Power batteries will generate a lot of heat during long-term use. If the heat cannot be removed in time, it will easily affect the service life of the power battery. Therefore, the battery box of the power battery is usually installed with a system with air cooling technology. Air cooling technology refers to the use of heat sinks or fans and other equipment on the outside of the battery to use wind power to remove the excess heat in the battery to achieve the purpose of cooling. It has been widely used in the field of electric vehicles.
[0003] However, when the existing new battery box air cooling system is in use, the cold air produced by the refrigeration equipment is usually sent to different positions in the same space through the air supply structure. In addition, since the batteries in the battery box are usually arranged relatively closely, the movement path of the cold air in the battery box is relatively long, so the refrigeration equipment needs to produce more cold air to meet the circulation of the cold air, resulting in high energy consumption of the refrigeration equipment. In addition, since the space inside the battery box is large and not divided, and since there is usually no heat dissipation structure on the top of the battery box, the heat in the battery box is more likely to be concentrated on the top of the inner side of the battery box, resulting in a large temperature difference inside the battery box, such as hot top and cold bottom, which is not conducive to the rapid cooling of the batteries inside the battery box. Utility Model Content
[0004] The purpose of the present invention is to provide a novel battery box air cooling system to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a new battery box air cooling system, comprising a shell, a top plate is provided on the top of the shell, three heat collecting boxes are fixedly connected to the top of the top plate, a heat exhaust pipe is passed through one side wall of the heat collecting box, a solenoid valve is installed inside the heat exhaust pipe, a side wall of the solenoid valve is electrically connected to a temperature sensor, a partition is engaged with the inner wall of the shell, a side wall of the shell is fixedly installed with a side wall of the shell, an air-conditioning outlet is provided on the front of the side wall air-conditioning, an air-conditioning outlet is provided on the outer side cover of the air-conditioning outlet, an air-conditioning return air outlet is provided on the back of the side wall air-conditioning, and an air-conditioning return air outlet is provided on the outer side cover of the air-conditioning return air outlet.

[0023] like Figures 1 to 4As shown, the new battery box air cooling system of this embodiment includes a casing 4, a top plate 1 is provided on the top of the casing 4, three heat collecting boxes 2 are fixedly connected to the top of the top plate 1, a heat exhaust pipe 3 is passed through one side wall of the heat collecting box 2, a solenoid valve 17 is installed inside the heat exhaust pipe 3, and a side wall of the solenoid valve 17 is electrically connected to a temperature sensor 11, a partition 5 is engaged with the inner wall of the casing 4, a side wall of the casing 4 is fixedly installed with a side wall of the casing 4, an air-conditioning outlet 18 is provided on the front of the side wall air-conditioning 8, an air-conditioning outlet 18 is provided on the outer side cover of the air-conditioning outlet 18 is provided with an air outlet duct 10, an air-conditioning return air port 19 is provided on the back of the side wall air-conditioning 8, and an air-conditioning return air port 19 is provided on the outer side cover of the air-conditioning return air port 19 is provided with a return air duct 9, three second openings 14 are provided on the front of the casing 4, a diverter plate 15 is fixedly connected to the middle of the second opening 14, and three first openings 7 are provided on the back of the casing 4.
[0024] Specifically, the interior of the casing 4 is divided into three cavities by the partition 5, and the three cavities are not interconnected, so that the interior of the battery box 13 can be divided into smaller spaces, which is more conducive to the flow of cold air inside the battery box 13, thereby shortening the movement path of cold air in the battery box 13, so that refrigeration equipment such as air conditioners only need to produce less cold air to meet the cooling of the batteries 13 in the battery box 13, thereby reducing the energy consumption of refrigeration equipment such as air conditioners. The top plate 1 is a detachable structure, so that the top of the casing 4 can be opened, which is conducive to the inspection or replacement of the temperature sensor 11 on the heat collection box 2. The function of the heat exhaust pipe 3 is to quickly discharge the hot air accumulated in the heat collection box 2 from the casing 4, thereby reducing the accumulation of hot air at the top of the inner side of the battery box 13 and reducing the large temperature difference between the top and bottom of the battery box 13, which is more conducive to the cooling of the batteries 13 in the battery box 13. The function of the solenoid valve 17 is to control the opening and closing of the heat exhaust pipe 3 to prevent cold air from flowing out of the heat collection box 2 and the heat exhaust pipe 3. The temperature sensor 11 is also connected to the controller, so that the temperature sensor 11 can control the opening and closing of the solenoid valve 17 through the controller after monitoring the internal temperature of the heat collecting box 2, thereby facilitating the timely opening and closing of the heat exhaust pipe 3. The function of the partition 5 is to divide the interior of the casing 4 into smaller spaces, making the space inside the casing 4 smaller, thereby shortening the path of the cold air flowing inside the casing 4. The side wall air conditioner 8 is a refrigeration device. The air outlet duct 10 can send the cold air generated by the air conditioner into the interior of the casing 4 through the second opening 14, and blow it directly to the front of the battery 13, so that the cold air can adhere to the outer wall of the battery 13 and flow to the first opening 7, thereby realizing rapid cooling of the battery 13 and shortening the path of the cold air flow. The cold air production required for cooling is reduced, thereby reducing the energy consumption of the refrigeration equipment. The function of the diverter plate 15 is to divert the cold air to both sides of the front of the battery 13 when blowing to the front of the battery 13, thereby facilitating the return speed of the cold air.
[0025] Furthermore, a cavity 6 is provided inside the partition 5, and a notch is provided at the top of the cavity 6. The function of the cavity 6 is to make the partition 5 a hollow structure, which has a better heat insulation effect, making it difficult for heat to be transferred between the spaces inside the casing 4 divided by the partition 5, thereby being more conducive to cooling the batteries 13 in the battery box 13.
[0026] Furthermore, a clip 16 is fixedly connected to the bottom end of the top plate 1, and the clip 16 is engaged with the notch. The top plate 1 is movably engaged with the casing 4 through the clip 16. The clip 16 can engage with the notch, so that the top plate 1 can be removed from the top of the casing 4, which is conducive to cleaning the inside of the heat collecting box 2.
[0027] Furthermore, a through opening is opened at the bottom of the heat collecting box 2, and the heat collecting box 2 is connected to the interior of the casing 4 through the through opening. The temperature sensor 11 is fixedly installed on the top of the inner side of the heat collecting box 2. The heat collecting box 2 can collect the heat in the independent space divided in the casing 4, thereby facilitating the discharge of heat outside the casing 4 and reducing the accumulation of heat in the casing 4.
[0028] Furthermore, a vertical frame 12 is placed inside the casing 4, and batteries 13 are placed on the top, middle and bottom of the vertical frame 12. The function of the vertical frame 12 is to allow the batteries 13 to be placed in the casing 4 in an orderly manner for cooling, thereby facilitating the cooling of the batteries 13.
[0029] Furthermore, the battery 13 is movably connected to the first opening 7 and the second opening 14 through the vertical frame 12. The first opening 7 and the second opening 14 are respectively facing the back and the front of the battery 13, so that the blown cold air can directly contact the outer shell of the battery 13, thereby facilitating the cooling of the battery 13.
[0030] Furthermore, the return air duct 9 is connected to the interior of the casing 4 through the first opening 7, and the outlet air duct 10 is connected to the interior of the casing 4 through the second opening 14. The first opening 7 and the second opening 14 are symmetrically distributed on the front and back of the casing 4, so that the cold air blown out from the second opening 14 enters the return air duct 9 from the first opening 7 after contacting the battery 13, thereby effectively shortening the movement path of the cold air in the casing 4.
[0031] The method of using this embodiment is as follows: when using the battery 13 box air cooling system of the present invention, it is necessary to first connect the system to an external power supply, then place the battery 13 and the vertical frame 12 for fixing the battery 13 into the independent small space separated by the partition 5 in the casing 4, then snap the top plate 1 with the top of the casing 4, so that the card strip 16 at the bottom end of the top plate 1 is inserted into the notch at the top of the cavity 6, so that the interior of the casing 4 is divided into multiple independent small spaces by the partition 5, then start the side wall air conditioner 8, so that the air outlet 18 of the side wall air conditioner 8 passes the cold air into the outlet duct 10 and enters the casing 4 through the second opening 14, and at the same time the second opening 1 The cold air blown out will be divided into two air flows by the diverter plate 15, so that the cold air can be dispersed to both sides after being blown to the front of the battery 13, then go around the outer wall of the battery 13 and enter the first opening 7, and then enter the return air duct 9 from the first opening 7. At the same time, the heat generated by the operation of the battery 13 will be squeezed by the cold air and flow upward, and then gather inside the heat collection box 2, and be monitored by the temperature sensor 11 at the same time. When the temperature sensor 11 detects that the temperature inside the heat collection box 2 exceeds the set value, it will send a signal to the controller, so that the controller controls the solenoid valve 17 in the heat exhaust pipe 3 to open, so that the heat accumulated in the heat collection box 2 is discharged in time through the heat exhaust pipe 3.
[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
