Embodiment 2

[0062] Figure 5 A schematic structural diagram of a cooling system provided by an embodiment of the present application.

[0063] Please refer to Figure 5 , the present embodiment provides a cooling system, including a water pump 20, a component to be cooled 30, a heat exchanger 40, and any expansion kettle 10 as above. The water pump 20, the component to be cooled 30, the heat exchanger 40 and the expansion kettle 10 pass through The channels are connected in sequence, wherein the heat exchanger 40 is connected to the mixed liquid inlet of the expansion kettle 10 , and the second channel of the expansion kettle 10 is connected to the water pump 20 .

[0064] Specifically, the component to be cooled 30 in this embodiment may be an engine, a motor, or a battery pack. The water pump 20 is used to provide circulation power for the entire system. Under the action of the water pump 20 , the mixture of cooling liquid and gas can circulate along the pipeline in the system to redu...

Embodiment 3

[0066] This embodiment provides an automobile, including the cooling system in Embodiment 2 above.

[0067] Specifically, the cooling system in this embodiment may be located in the engine compartment of the vehicle or in the space between the chassis and the vehicle body. Because the automobile of this embodiment has adopted the cooling system of the above-mentioned embodiment two, there is no need to arrange a special liquid-gas separator in the cooling system, which helps to reduce the number of parts and the total weight in the cooling system, and also reduces the cooling system temperature. The number of pipes in the car reduces the cost and is conducive to the lightweight of the car.

Abstract

The application provides an expansion kettle, a cooling system and an automobile. The expansion kettle includes a kettle body, and the kettle body is provided with a first chamber and a second chamber and a first through hole communicating the first chamber and the second chamber; the kettle The body is provided with a pipeline communicating with the interior of the pot body, the side wall of the pipeline is provided with a mixed liquid inlet, and a second partition is arranged inside the pipeline, one end of the second partition is connected to the side wall of the pipeline, and the other end of the second partition is One end extends to the mixed liquid inlet, so that the first channel and the second channel are formed in the pipeline; the first end of the first channel is connected to the first chamber, the second end of the first channel is closed, and the first end of the second channel is connected to The second chamber and the second end of the second channel are used to connect with the water pump. The expansion kettle of the present application also has the function of gas-liquid separation, so there is no need to install a special liquid-gas separator in the cooling system, which is conducive to reducing the number of parts and total weight in the cooling system, reducing the cost and benefiting the automobile. lightweight.

Description

technical field [0001] The application relates to the manufacturing technology of auto parts, in particular to an expansion kettle, a cooling system and an automobile. Background technique [0002] The main job of the car cooling system is to dissipate heat into the air to prevent parts from overheating, and the expansion kettle is an important part in the car cooling system. The expansion kettle can store the coolant and replenish the coolant for the cooling system in time when the coolant is lacking in the cooling system. [0003] In the solution of the related technology, the cooling system installed on the electric vehicle includes an expansion kettle, a liquid-gas separator, an electronic water pump, components to be cooled (such as battery packs, motors, etc.) and a heat exchanger, a liquid-gas separator, and an electronic water pump. , The components to be cooled and the heat exchanger are connected in sequence through pipelines to form a closed loop; the expansion k...
