Technical Field
[0001] This utility model relates to the field of new energy vehicle technology, specifically a heat dissipation device for the battery compartment of a new energy locomotive. Background Technology
[0002] With the rapid development of the new energy vehicle industry, the power battery, as its core component, directly affects the vehicle's range, safety, and lifespan. However, power batteries generate a large amount of heat during operation. If this heat cannot be dissipated effectively and in a timely manner, it will lead to excessively high battery temperatures, affecting battery performance and safety, and even causing serious problems such as thermal runaway. Therefore, developing efficient and reliable heat dissipation devices is crucial for the battery compartments of new energy vehicles. Although some existing heat dissipation devices are inexpensive, their heat dissipation effect is limited and cannot meet the heat dissipation requirements of high-energy-density and high-power-density power batteries. Although some devices are simple in structure and low in cost, their heat dissipation efficiency is low and they are easily affected by the external environment, resulting in unstable heat dissipation. Some heat dissipation devices have complex designs, occupying a lot of battery compartment space and reducing the vehicle's energy density and range. Some high-end heat dissipation devices have good heat dissipation effects, but their complex structures and high maintenance costs increase the vehicle's operating costs. Currently, some heat dissipation devices lack intelligent temperature control systems and cannot automatically adjust the heat dissipation power according to the actual battery temperature, resulting in energy waste or insufficient heat dissipation. To address these issues, we propose a heat dissipation device for the battery compartments of new energy vehicles. Utility Model Content

[0025] The refrigeration device 11 includes a heat dissipation water pipe 12, a fixing column 13, a cooling plate 14, and an installation platform 16. The installation platform 16 is provided at the bottom of the refrigeration device 11. Fixing columns 13 are fixedly installed around the bottom of the installation platform 16. The refrigeration device 11 is fixedly installed inside the bottom of the base plate 2 by multiple sets of fixing columns 13.

The heat dissipation water pipe 12 is fixedly installed on the side of the installation platform 16 away from the cooling plates 14.
[0026] Furthermore, a sealing strip 9 is fixedly installed around the bottom of the top cover 1.
[0027] Furthermore, a sealing groove 10 is provided at the top of the base plate 2, and the top cover 1 and the base plate 2 are connected together by a sealing strip 9 and the sealing groove 10.
[0028] Furthermore, the cooling chip 14 is a semiconductor cooling chip, and the medium inside the heat dissipation pipe 12 is a refrigerant. Through the semiconductor cooling chip and the refrigerant, combined with the design of the air guide slot 2, the device can efficiently conduct the heat generated by the battery and dissipate it to the external environment, ensuring that the battery compartment temperature is always kept within a safe range, extending the battery life and improving system stability.
[0029] Furthermore, the integrated connector 4 has a groove on the side facing away from the base plate 2 to form a power supply connector 15, and the inlet and outlet of the heat dissipation water pipe 12 are respectively fixedly installed on both sides of the power supply connector 15.
[0030] Working principle: The device is equipped with two temperature sensors—a first temperature sensor 7 and a second temperature sensor 8—installed inside the upper cover 1 on one side near the integrated connector 4 and the other away from it, respectively. These two sensors are responsible for monitoring the temperature distribution inside the battery compartment in real time and transmitting the temperature data to the control unit 6. After receiving the data from the temperature sensors, the control unit 6 analyzes and judges according to the preset temperature threshold. If the temperature inside the battery compartment exceeds the normal range, the control unit will activate the cooling device 11 to cool it down. The cooling device 11 consists of a heat dissipation pipe 12, a fixing column 13, a cooling element 14, and a mounting platform 16. The cooling element 14 is a semiconductor cooling element; when powered on, it absorbs heat on one side (the battery compartment side) and releases heat on the other side (the battery compartment side). On the side of the cooling water pipe 12, the cooling fin 14 absorbs heat from inside the battery compartment, lowering the battery compartment temperature. Simultaneously, the generated heat is transferred to the cooling water pipe 12 via the mounting platform 16. The cooling water pipe 12 is filled with refrigerant, which carries away the heat generated by the cooling fin 14 during circulation. The refrigerant is connected to an external cooling system through its inlet and outlet for final heat dissipation. The inlet and outlet of the cooling water pipe 12 are fixedly installed on both sides of the power supply connector 15 on the integrated connector 4. The power supply connector 15 not only provides power to the cooling device but also serves as the interface for the refrigerant circulation. After being cooled by an external cooling system such as a radiator or fan, the refrigerant flows back into the cooling water pipe 12, forming a circulation. The upper cover 1 and the bottom plate 2 are connected by a sealing strip 9 and a sealing... The sealing groove 10 is tightly fitted to ensure the airtightness of the battery compartment, preventing external dust and moisture from entering and reducing heat loss. The fixing block 5 is used to fix the device in the appropriate position in the battery compartment, while the fixing column 13 ensures that the cooling device 11 is firmly installed inside the base plate 2. The entire heat dissipation process is intelligently controlled by the control unit 6, which automatically adjusts the cooling intensity according to the actual temperature of the battery compartment to achieve the best heat dissipation effect. At the same time, the design of the integrated connector 4 makes the power supply and coolant circulation of the cooling device more convenient, improving the reliability and maintainability of the system. When the locomotive is moving, the external airflow will flow with the movement of the vehicle. The design of the air guide duct 3 can guide these airflows through the bottom of the battery compartment in a more efficient way, increasing the airflow in the base plate 2 and its surrounding area. The directional airflow, guided by the dynamic speed, can more effectively remove the heat generated by the battery, thereby reducing the temperature of the battery compartment and improving heat dissipation efficiency. The raised design of the air guide slot 3 provides an additional protective barrier for the base plate 2 at a physical level. During locomotive operation, especially on complex or uneven roads, various obstacles or road protrusions may be encountered. The presence of the air guide slot 3 can reduce the chance of the base plate 2 coming into direct contact with these potential threats, thereby reducing the risk of the base plate being scratched or scraped. In addition, the material and structure of the air guide slot 3 are often carefully selected and designed to ensure that it has a certain degree of impact resistance and wear resistance, further enhancing the protection of the base plate 2. By guiding the airflow smoothly through the bottom of the battery compartment, the generation of turbulence and vortices is reduced.This reduces the drag coefficient, improving the locomotive's fuel economy or electricity utilization efficiency. Simultaneously, reducing airflow turbulence also helps reduce noise. The air guide slot 3 not only plays a crucial role in optimizing heat dissipation in the battery compartment cooling system of new energy locomotives, but also provides an effective protective barrier for the floor plate 2 through its unique design, potentially reducing wind resistance and noise to some extent. These functions collectively enhance the overall performance and reliability of the locomotive.
