Description

Technical Field

[0001] The utility model relates to the technical field of battery boxes, in particular to a battery box with an efficient cooling structure. Background Technique

[0002] With the popularization of new energy vehicles, the power battery, as the core component of new energy vehicles, has become an important direction for future energy transformation. Since a large amount of heat will be released due to the thermal effect of current during the charging and discharging processes of the power battery, the power battery is prone to failures or even explosions due to excessive temperature. Therefore, cooling equipment and structures such as sidewall air conditioners are usually installed in the battery box to cool down the power battery.

[0003] However, when the existing power battery is placed in the battery box, due to the small space in the battery box and the lack of partitioning, the flow paths of the cold air entering the battery box and the heat generated by the power battery are relatively chaotic, resulting in the low temperature brought by the cold air not being able to fully contact the power battery. In order to enable the cold air to fully contact the power battery, it is necessary to increase the refrigeration power of the air conditioner, so more energy is consumed and it is not energy-saving. In addition, in the existing battery box, since the power battery continuously generates heat and the subsequent cold air replenishment speed is slow, it is easy to cause heat accumulation in the battery box, resulting in a poor refrigeration effect of the cooling structure in the battery box. Content of the Utility Model

[0004] The purpose of the utility model is to provide a battery box with an efficient cooling structure to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A battery box with an efficient cooling structure, including a rectifying box, a sidewall air conditioner is fixedly installed on the back of the rectifying box, an air inlet is opened in the middle of the back of the rectifying box, a top plate penetrates through the top of the front of the rectifying box, a middle plate penetrates through the middle of the front of the rectifying box, a bottom plate penetrates through the bottom of the front of the rectifying box, a seat plate is fixedly connected to the bottom end of the rectifying box, channels are opened inside the top plate, the middle plate and the bottom plate, cold conduction sheets are embedded at the top ends of the middle plate, the bottom plate and the seat plate, air outlets are opened on one side of the bottom ends of the top plate, the middle plate and the bottom plate, a flow guiding plate is arranged at the bottom of the air outlet, a vertical plate is fixedly connected to one end of the seat plate away from the rectifying box, and air guiding pipes are fixedly connected to both side walls of the rectifying box.

[0013] 1.

[0023] Such as Figures 1 to 4As shown in the figure, the battery box of this embodiment has an efficient cooling structure, including a rectifier box 1. A sidewall air conditioner 13 is fixedly installed on the back of the rectifier box 1. An air inlet 3 is opened in the middle of the back of the rectifier box 1. A top plate 4 penetrates through the top of the front of the rectifier box 1. A middle plate 8 penetrates through the middle of the front of the rectifier box 1. A bottom plate 9 penetrates through the bottom of the front of the rectifier box 1. A seat plate 10 is fixedly connected to the bottom end of the rectifier box 1. Channels 15 are opened inside the top plate 4, the middle plate 8, and the bottom plate 9. Cold conduction sheets 7 are embedded at the top ends of the middle plate 8, the bottom plate 9, and the seat plate 10. Air outlets 11 are opened on one side of the bottom ends of the top plate 4, the middle plate 8, and the bottom plate 9. A flow guide plate 6 is arranged at the bottom of the air outlet 11. One end of the seat plate 10 away from the rectifier box 1 is fixedly connected to a vertical plate 5. Air ducts 2 are fixedly connected to both side walls of the rectifier box 1.

[0024] Specifically, the rectifier box 1 is a cold air redistribution structure and is an integral structure with the top plate 4, the middle plate 8, and the bottom plate 9. The top plate 4, the middle plate 8, and the bottom plate 9 have the same length and have better load-bearing capacity, capable of placing heavier items such as power batteries 16. The sidewall air conditioner 13 can be used as the refrigeration device of the battery 16 box, capable of providing sufficient cold source inside the battery 16 box. The air inlet 3 enables the cold air generated by the sidewall air conditioner 13 to smoothly enter the inside of the rectifier box 1, and then enter the corresponding channels 15 along the cavity 17, so that the cold air carries low temperature into the inside of the top plate 4, the middle plate 8, and the bottom plate 9, enabling the cold air to fully contact the batteries 16 in the battery 16 box, reducing waste of cold air, and being more energy-efficient. The cold conduction sheets 7 are made of metal materials, enabling the cold air to directly conduct low temperature to the bottom of the battery 16 when flowing in the channels 15, enabling the battery 16 to fully contact with the low temperature directly, thereby improving the cooling effect of this structure. The function of the air outlet 11 is to enable the cold air to blow out from the other side of the channel 15 and form a relatively fast airflow, enabling the heat accumulated above the battery 16 to be quickly rushed towards the side wall of the rectifier box 1, thereby reducing the accumulation of heat in the battery box. The flow guide plate 6 can make the cold air flow blown out from the air outlet 11 change from the vertical direction to the horizontal direction, enabling the airflow to quickly take away the heat accumulated above the battery 16 in a timely manner. The function of the vertical plate 5 is to increase the stability of the structure, and at the same time can guide the airflow blown out from the air outlet 11, enabling the airflow blown out from the air outlet 11 to be smoothly adjusted to the horizontal direction. The air ducts 2 are rectangular structures, capable of guiding the airflow flowing along the side wall of the rectifier box 1 to the pipe orifice of the air ducts 2, enabling the air ducts 2 to drain the heat carried by the airflow to the air return port 14 of the sidewall air conditioner 13, thereby reducing the accumulation of heat in the battery 16 box.

[0025] Furthermore, a cavity 17 is formed inside the rectifying box 1. The air inlet 3 is in communication with the inside of the cavity 17, and the channel 15 is also in communication with the inside of the cavity 17. This allows the cold air blown out by the sidewall air conditioner 13 to enter the cavity 17 through the air inlet 3 and then enter the channel 15, thus enabling the smooth entry of the cold air.

[0026] Furthermore, an air outlet 18 is provided on the front surface of the sidewall air conditioner 13. The air outlet 18 is movably and snap-fitted with the air inlet 3. The air outlet 18 allows the cold air to smoothly enter the cavity 17 of the rectifying box 1 for redistribution, ensuring that the cooling structure has an adequate cold source.

[0027] Furthermore, air return openings 14 are provided on both sidewalls of the sidewall air conditioner 13, near the pipe orifice on the back surface of the air duct 2. This enables the air flow inside the air duct 2 to smoothly enter the air return duct, allowing the cold and hot air flows inside the battery 16 box to form a microcirculation, thereby enhancing the refrigeration effect of the cooling structure.

[0028] Furthermore, one end of the top plate 4, the middle plate 8, and the bottom plate 9 away from the rectifying box 1 are fixedly connected to the vertical plate 5. Batteries 16 are placed on the top of the middle plate 8, the bottom plate 9, and the seat plate 10. The batteries 16 are placed on the heat conducting sheets 7, enabling the batteries 16 to directly contact the low temperature brought by the cold air, thus directly cooling the batteries 16 and enhancing the cooling effect of this cooling structure.

[0029] Furthermore, the flow guiding plate 6 is fixedly connected to the sidewall of the vertical plate 5. The flow guiding plate 6 is fixedly connected to the air outlet 11 through the vertical plate 5. The air flow blown out from the air outlet 11 will have its direction changed by the flow guiding plate 6, causing the air flow to return to the front of the rectifying box 1, thus facilitating the transfer of the heat at the top of the battery 16 to the sidewall of the rectifying box 1.

[0030] Furthermore, cards 12 are fixedly connected to the bottom ends of the top plate 4, the middle plate 8, and the bottom plate 9. The cards 12 are in the form of inclined sheets and can interfere with the blowing air flow, increasing the flow rate of the air flow. This is more conducive to the air flow carrying away the accumulated heat, thereby enhancing the cooling effect of this cooling structure.

[0031] The usage method of this embodiment is as follows: When using this battery box with an efficient cooling structure, the battery 16 needs to be steadily placed on the heat conduction sheets 7 of the middle plate 8, the bottom plate 9 and the base first. Then, connect the external power supply, and start the sidewall air conditioner 13 on the back sidewall of the rectifying box 1, so that the sidewall air conditioner 13 blows cold air from the air outlet 18 into the air inlet 3, and then enters the cavity 17 of the rectifying box 1. Then, it enters the channel 15 communicating with the cavity 17 through the cavity 17, and then enters the interiors of the top plate 4, the middle plate 8 and the bottom plate 9 along the channel 15, so that the heat conduction sheets 7 on the middle plate 8 and the bottom plate 9 conduct the low temperature brought by the cold air to the battery 16, enabling the battery 16 to be directly cooled, and causing the heat generated by the battery 16 to rise. At the same time, the cold air will continue to flow along the channel 15. When it flows to the end of the channel 15, it will be blown out from the air outlet 11 and flow downward along the sidewall of the vertical plate 5. When it contacts the deflector 6 directly below the air outlet 11, it will change from the vertical direction to the horizontal direction and flow back to the front of the rectifying box 1. At the same time, it will quickly drive the heat accumulated at the card 12 to the front of the rectifying box 1. Until the flowing-back cold air and heat contact the outer wall of the rectifying box 1, they will enter the air duct 2 from both sides of the rectifying box 1, and finally enter the air return port 14 from the pipe orifice of the air duct 2.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
