Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a three-in-one expansion kettle. Background Technology

[0002] In recent years, as drivers have gained more driving experience, their awareness of safety and comfort has increased, and people's demands for automotive comfort have risen. Therefore, many automobile manufacturers are strengthening the development of automotive thermal management systems in their research and development, leading to higher requirements for thermal management components and increased component integration.

[0003] Currently, thermal management expansion tanks are mostly distributed, which takes up a lot of space and the piping is often complicated and messy. This leads to an increase in the overall weight of the vehicle, and consequently, an increase in fuel consumption.

[0004] Therefore, it is necessary to design a three-in-one expansion tank to improve the integration of thermal management components, reduce space occupation and piping, and facilitate the layout of other vehicle components while ensuring the vehicle's cooling effect. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a three-in-one expansion tank that improves the integration of thermal management components, reduces space occupation and piping, and facilitates the arrangement of other components in the vehicle while ensuring the vehicle's cooling effect.

[0006] To achieve the above objectives, this utility model is a three-in-one expansion kettle, comprising a kettle body, a heater exhaust pipe, a heater circuit water inlet, a heater pressure cap, a battery and motor exhaust pipe, a battery and motor circuit water inlet, a battery and motor pressure cap, an isolation grid, and an internal grid. The interior of the kettle body is divided into a heater circuit coolant chamber and a battery and motor circuit coolant chamber by the isolation grid. The heater circuit coolant chamber and the battery and motor circuit coolant chamber are respectively provided with an internal grid. The bottom and top of the internal grid are respectively provided with a flow hole and an exhaust hole. The top of the kettle body is provided with a heater pressure cap and a battery and motor pressure cap. The sides of the kettle body are respectively provided with a heater exhaust pipe and a battery and motor exhaust pipe. The bottom of the kettle body is provided with a heater circuit water inlet and a battery and motor circuit water inlet. The heater pressure cap, heater exhaust pipe, and heater circuit water inlet are connected to the heater circuit coolant chamber. The battery and motor pressure cap, battery and motor exhaust pipe, and battery and motor circuit water inlet are connected to the battery and motor circuit coolant chamber.

[0007] The pressure threshold of the heating air pressure cover is 90 kPa, and the pressure threshold of the battery and motor pressure cover is 50 kPa.

[0008] The kettle body has three mounting points, which are located at the bottom and both rear ends of the kettle body.

[0009] Compared with the prior art, this utility model integrates the battery cooling circuit, motor cooling circuit, and heater circuit of an electric vehicle into an expansion tank, reducing the number of tanks and the space occupied, simplifying the pipeline routing, saving layout space, and facilitating the overall vehicle layout. At the same time, the tank is divided into two chambers by a grid to prevent coolant cross-flow. The grid inside the chamber is provided with flow holes and vent holes to avoid air resistance affecting the vehicle's cooling effect. Attached Figure Description

[0016] The present invention will now be further described with reference to the accompanying drawings.

[0017] See Figures 1-6This utility model is a three-in-one expansion tank, including a tank body, a heater exhaust pipe, a heater circuit water inlet, a heater pressure cap, a battery and motor exhaust pipe, a battery and motor circuit water inlet, a battery and motor pressure cap, an isolation grid, and an internal grid. The interior of the tank body 7 is divided by the isolation grid 73 into a non-connected heater circuit coolant cavity 71 and a battery and motor circuit coolant cavity 72. The heater circuit coolant cavity 71 and the battery and motor circuit coolant cavity 72 are respectively provided with an internal grid 74. The bottom and top of the internal grid 74 are respectively provided with a flow hole 741 and an exhaust hole 742, which facilitates the flow of coolant inside the cavity and avoids air resistance affecting the vehicle cooling effect. The top of the kettle body 7 is equipped with a warm air pressure cover 4 and a battery and motor pressure cover 3. The sides of the kettle body 7 are respectively equipped with a warm air exhaust pipe 1 and a battery and motor exhaust pipe 2. The bottom of the kettle body 7 is equipped with a warm air circuit water inlet 6 and a battery and motor circuit water inlet 5. The warm air pressure cover 4, the warm air exhaust pipe 1, and the warm air circuit water inlet 6 are connected to the warm air circuit coolant cavity 71. The battery and motor pressure cover 3, the battery and motor exhaust pipe 2, and the battery and motor circuit water inlet 5 are connected to the battery and motor circuit coolant cavity 72.

[0018] To prevent material corrosion and aging due to alternating high and low temperatures, this invention uses materials that are resistant to ethylene glycol and high temperatures, such as PA66+GF30.

[0019] The pressure threshold of the heater pressure cover 4 is 90 kPa, and the pressure threshold of the battery and motor pressure cover 3 is 50 kPa, which facilitates the exhaust of the circuit.

[0020] The coolant chamber 71 of the heating circuit and the coolant chamber 72 of the battery and motor circuit are reserved with an expansion volume space of more than 15% to avoid coolant overflow during thermal expansion and reduce damage to the kettle body 7 due to thermal expansion.

[0021] The temperature of the coolant in the battery and motor circuits is different from that in the heater circuit. The two chambers contain coolants of different temperatures separately, which reduces internal heat exchange and is more conducive to the cooling effect of each circuit. It also avoids the problem of heat loss caused by internal circuit convection.

[0022] The kettle body 7 has three mounting points 75, located at the bottom and rear ends of the kettle body 7. When installing the kettle, only three bolts are needed to secure the three mounting points 75, reducing the complexity of the matching structure.

[0023] This invention integrates the cooling of the battery and motor into the battery and motor circuit coolant chamber 72 inside the reservoir. The battery and motor circuits share a common piping. The heater circuit coolant chamber 71 serves as the reservoir point for the heater circuit cooling circuit. During use, coolant is introduced into the corresponding water pumps through the heater circuit inlet 6 and the battery and motor circuit inlet 5, where it is pressurized and circulates in each circuit. Gas generated during circulation returns to the reservoir body 7 through the heater exhaust pipe 1 and the battery and motor exhaust pipe 2. Bleeding is required after the vehicle rolls off the production line for the first time or after subsequent maintenance and replacement of the three-in-one expansion tank.

[0024] This invention integrates the battery cooling circuit, motor cooling circuit, and heater circuit of an electric vehicle into a single expansion tank, reducing the number of tanks and the space they occupy, simplifying the piping layout, saving space, and facilitating vehicle layout. It can also reduce the number of mold sets and lower costs. At the same time, the tank is divided into two chambers by a grid to prevent coolant cross-flow. The grid inside the chamber is equipped with flow holes and vent holes to avoid air resistance affecting the vehicle's cooling effect.
