Description

Technical Field

[0001] This invention relates to the field of vehicle cooling system technology, and in particular to an integrated water tank and vehicle. Background Technology

[0002] The car's cooling system is equipped with an auxiliary water tank, also called an expansion tank or coolant replenishment tank, which is connected to the main water tank. It mainly works by utilizing the thermal expansion and contraction properties of coolant: when the engine is running and warming up, the coolant that expands and overflows will flow into the auxiliary water tank for storage; after the vehicle is turned off and cooled down, a negative pressure is formed inside the system, and the coolant in the tank will flow back to replenish the main water tank.

[0003] In addition, the auxiliary water tank can balance the internal air pressure of the cooling system and prevent air from entering the pipes, effectively avoiding problems such as air lock and pipe pressure damage. Because the auxiliary water tank is located at a high position in the cooling system, air and water vapor in the pipes will rise due to their lower density and eventually be discharged through the venting structure of the lid, completing the system exhaust.

[0004] Currently, most auxiliary water tanks rely on a single cap for water replenishment, venting, and pressure balancing, with all functions sharing the same channel. Coolant and air bubbles mix and interfere with each other within this channel, causing not only poor venting but also affecting normal coolant filling. Poor venting allows a large number of free air bubbles to enter the water pump with the coolant. These bubbles collapse instantly in the high-pressure zone, generating high-frequency shock waves and localized negative pressure that continuously impact metal and rubber components, causing cavitation damage. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated coolant reservoir and vehicle to solve the problems existing in the prior art, enabling smooth venting of the coolant reservoir, facilitating coolant filling, and improving the operational stability and service life of the cooling system.

[0006] To achieve the above objectives, the present invention provides the following solution: This invention provides an integrated kettle, comprising a kettle body and an electronic water pump; the kettle body includes a liquid storage tank, a main water inlet channel, a replenishment channel, and a pressure cap; the liquid storage tank is internally divided into a water storage chamber and a replenishment chamber that are interconnected; the main water inlet channel is connected to the water storage chamber, and a main water outlet is provided at the bottom of the water storage chamber; the replenishment channel is connected to the replenishment chamber; the top of the water storage chamber has a pressure relief port, and the pressure cap is fitted to the pressure relief port and connected to the water storage chamber, and the pressure cap has a built-in pressure valve for achieving system pressure relief and air pressure balance; the electronic water pump is fixedly installed at the bottom of the liquid storage tank, and the water inlet pipe of the electronic water pump is sealed and inserted into the main water outlet.

[0014] The present invention achieves the following technical effects compared to the prior art: This invention provides an integrated water tank and vehicle, with the main water inlet channel and the replenishment channel respectively connected to the water storage chamber and the replenishment chamber of the coolant reservoir. This ensures that the replenishment path and the air collection and exhaust path do not interfere with each other, guaranteeing smooth exhaust of the cooling system and convenient coolant filling. It solves the problem of mixed air and liquid in traditional single-channel auxiliary water tanks. It effectively controls the number of air bubbles in the cooling system, significantly reduces the risk of cavitation, effectively protects core components such as the electronic water pump, water pipes, and seals, and extends the overall service life.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The purpose of this invention is to provide an integrated coolant reservoir and vehicle to solve the problems existing in the prior art, enabling smooth venting of the coolant reservoir, facilitating coolant filling, and improving the operational stability and service life of the cooling system.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1 This embodiment provides an integrated kettle, such as Figures 1-5As shown, the system includes a kettle body 1 and an electronic water pump 2. The kettle body 1 includes a liquid storage tank 3, a main water inlet channel 4, a replenishment channel 5, and a pressure cover 6. The liquid storage tank 3 is internally divided into a water storage chamber 7 and a replenishment chamber 8, which are interconnected. The water storage chamber 7 is used for system gas collection, pressure regulation, and main liquid flow, while the replenishment chamber 8 is used for independent replenishment operations. The main water inlet channel 4 is connected to the water storage chamber 7 and is used to connect the circulating coolant and mixed gas of the cooling system. The bottom of the water storage chamber 7 has a main water outlet 9. The replenishment channel 5 is connected to the replenishment chamber 8 to form an independent replenishment path. The top of the water storage chamber 7 has a pressure relief port, and the pressure cover 6 is installed on the pressure relief port and connected to the water storage chamber 7. The pressure cover 6 has a built-in pressure valve to achieve system pressure relief and gas pressure balance. The electronic water pump 2 is fixedly installed at the bottom of the liquid storage tank 3, and the water inlet pipe 15 of the electronic water pump is sealed and inserted into the main water outlet 9. The water outlet pipe 16 of the electronic water pump is connected to the cooling part of the battery in the cooling system. The water storage chamber 7 serves as a dedicated chamber for the main circulation, air collection, and pressure regulation of the cooling system, receiving coolant and mixed gases returning from the cooling pipes. The replenishment chamber 8, in conjunction with the independent replenishment channel 5, serves as a dedicated filling passage. These two passages each perform their specific functions, eliminating the need to occupy the exhaust and circulation channels during coolant filling. The filling process is free from airflow and air bubble interference, resulting in low filling resistance and smooth operation. Simultaneously, the circulating air bubbles and coolant do not interfere with the filling process. This solves the problems of traditional auxiliary water tanks sharing the same channel for water replenishment, circulation, and exhaust, leading to coolant and air bubble mixing, mutual interference, poor exhaust, and obstructed filling. When the engine warms up and the coolant thermally expands, the internal system pressure increases. The pressure valve opens in a timely manner to release excess pressure and gas, preventing the cooling system pipes and seals from bursting due to high pressure. When the system cools down and forms a negative pressure, the vacuum structure of the pressure cap 6 synchronously balances the internal and external air pressure, ensuring normal coolant return and maintaining the system pressure within the rated range. The electronic water pump 2 is fixedly integrated with the bottom of the reservoir 3. Compared to the traditional separate structure of the auxiliary water tank and the external electronic water pump 2, this design eliminates the main water outlet channel on the reservoir body 1 and uses the water outlet pipe 16 of the electronic water pump as a unified water outlet channel. This reduces the number of intermediate connecting hoses, adapters, and other components, resulting in a simpler pipeline and reducing the risk of pipe bending, compression, loosening, and leakage. Furthermore, the water pump is directly integrated into the bottom of the reservoir 3, shortening the coolant delivery path, reducing pipeline flow resistance, increasing coolant circulation speed, and improving the heat exchange efficiency of the cooling system. The overall integrated design occupies less installation space in the engine compartment, facilitating vehicle layout, assembly, and subsequent maintenance. The rigid fixation of the water pump and reservoir 3 ensures synchronized operation and vibration, reducing relative wear between components.

[0022] In a further preferred embodiment of this invention, the end of the replenishment channel 5 away from the storage tank 3 is used to connect with the main water tank. The replenishment channel 5 is connected to the main water tank to form an independent replenishment flow channel, which makes it convenient to add coolant without interference. With the help of the electronic water pump 2 to force the circulation of the circuit medium, the gas accumulated in the battery cooling circuit can be transported to the water storage chamber 7 and discharged smoothly through the pressure valve, realizing active venting of the circuit.

[0023] In a further preferred embodiment of this invention, the pressure cover 6 is connected to the main water tank via the exhaust channel 10, forming a through-type exhaust passage, allowing the gas in the cooling system to be uniformly discharged through the main water tank. This achieves synchronized regulation of air pressure across the entire system, ensures a smooth exhaust path and high exhaust efficiency, and effectively prevents gas stagnation that could cause air resistance.

[0024] In the implementation of this embodiment, it is further preferred that, as follows: Figures 6-8 As shown, a horizontal baffle 11 is installed inside the water storage chamber 7. The horizontal baffle 11 is located below the outlet of the main water inlet channel 4 and directly above the main water outlet 9. The horizontal baffle 11 divides the internal space of the water storage chamber 7 into zones for flow guidance, constraining the coolant to flow along a preset path, suppressing disorderly rolling and turbulence of the liquid in the chamber, and making the liquid flow state more stable. By blocking and buffering, the flow velocity of the coolant is reduced, the surface disturbance is weakened, and the entrainment of external air during the flow is reduced, thereby reducing the generation of free bubbles from the source. The stable flow field disrupts the environment for bubble adhesion and aggregation, avoids the accumulation of large amounts of bubbles, and alleviates the problems of air accumulation and air resistance in the system. In a further preferred embodiment, to accommodate the horizontal anti-surge baffle 11, multiple vertical baffles 12 are installed within the water storage cavity 7. These vertical baffles 12, in conjunction with the horizontal anti-surge baffle 11, divide the cavity into multiple interconnected small chambers. This serves two purposes: firstly, it gradually buffers coolant sloshing, suppressing liquid splashing and turbulent air entrainment, dispersing bubbles, preventing bubble aggregation, improving venting efficiency, and reducing the risk of cavitation; secondly, it strengthens the structure of the kettle body 1, increasing shell strength. Simultaneously, it results in a more stable liquid surface, more accurate liquid level observation, and reduces abnormal noises caused by liquid impact.

[0025] In a further preferred embodiment of this invention, the liquid storage tank 3 includes an integrally formed upper tank portion 17 and a lower tank portion 18, and the electronic water pump 2 is fixedly connected to the lower tank portion 18 by bolts.

[0026] In a further preferred embodiment of this invention, the coolant reservoir 3 is made of a transparent material and is equipped with a low level line 13 and a high level line 14. The transparent material of the reservoir 3, combined with the high and low level markings, allows for direct observation of the internal coolant level. The level can be quickly determined without disassembling components, making inspection convenient and efficient. Using the high and low level lines as a reference for filling allows for precise control of the coolant filling amount, preventing overfilling or underfilling, and ensuring the cooling system operates under rated conditions. The transparent reservoir 3 also allows for real-time observation of the liquid flow and bubble status within the cavity, facilitating timely detection of faults such as gas leakage, abnormal bubbling, and seepage, thus improving troubleshooting efficiency.

Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
