Description

Technical Field

[0001] This utility model relates to the technical field of thermal management systems and their components, specifically an integrated kettle, a thermal management system, and a vehicle using the same. Background Technology

[0002] The battery packs, motors, and electronic control devices of new energy vehicles all generate a significant amount of heat. Additionally, the passenger compartment of new energy vehicles requires air conditioning. Therefore, new energy vehicles are generally equipped with thermal management systems to meet the thermal management needs of these devices / systems. Furthermore, the battery packs and power conversion devices (such as inverters, converters, and power converters containing various power electronic components) of energy storage systems also generate a significant amount of heat. Therefore, energy storage systems are also generally equipped with thermal management systems to meet the thermal management needs of these devices / systems.

[0003] Liquid medium circulation channels are an important component of thermal management systems, serving the functions of heat exchange and heat storage.

[0004] The liquid medium circulation channel in the thermal management system is usually equipped with an electric water pump to drive the liquid medium circulation flow, and also with a water tank (usually called "auxiliary water tank" or "expansion tank" in new energy vehicles) to store the liquid medium and provide expansion space for the liquid medium.

[0005] In the prior art, the aforementioned water tank is usually roughly spherical, hemispherical, or square. That is, the length of the water tank in the prior art is roughly equal on the X-axis, Y-axis, and Z-axis. Some models with limited installation space (such as narrow installation positions or insufficient engine compartment space) will find it difficult to install the aforementioned water tank. If the length of the water tank on the X-axis, Y-axis, and Z-axis is reduced proportionally, the volume of the water tank will be greatly reduced, thereby limiting the performance of the thermal management system.

[0006] In conclusion, how to provide integrated water tanks that fit the installation space of vehicles has become an urgent problem to be solved. Utility Model Content
