Description

Technical Field

[0001] This utility model relates to the field of preparation technology of thermal management fluid for new energy vehicles, and specifically to a mixing and blending vessel for thermal management fluid for new energy vehicles. Background Technology

[0002] New energy vehicle thermal management fluid is a fluid medium specifically used to regulate and control the operating temperature of core components of new energy vehicles (such as batteries, motors, and electronic control systems). New energy vehicle thermal management fluid includes ultrapure water, ethylene glycol, and additives. In the preparation of new energy vehicle thermal management fluid, ultrapure water and ethylene glycol are first thoroughly and uniformly mixed, and then additives are added to complete the preparation.

[0003] To ensure thorough and uniform mixing of ultrapure water and ethylene glycol, mechanical stirring equipment is often used. However, because the stirring paddle is positioned on the central axis of the tank, the bottom and inner wall of the tank become dead zones. To achieve thorough and uniform mixing, the mixing of ethylene glycol and ultrapure water requires a long time, resulting in low efficiency. Furthermore, mechanical stirring can easily introduce metal particles due to the material of the stirring equipment itself and wear on the stirring paddle, contaminating the mixture, leading to increased conductivity, decreased purity, and a decline in the quality of the prepared thermal management fluid for new energy vehicles (this decline in quality, in practical applications, results in lower heat exchange efficiency of the thermal management fluid for new energy vehicles, reducing the overall performance of the system). Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a mixing and blending vessel for thermal management fluid of new energy vehicles, which reduces stirring time, improves stirring efficiency, improves purity, and improves the quality of thermal management fluid preparation for new energy vehicles.

[0005] The technical solution adopted in this utility model is as follows: a mixing and blending vessel for thermal management fluid of new energy vehicles, including a vessel body and a stirring assembly for stirring a mixture of ethylene glycol and ultrapure water. The stirring assembly includes an exhaust component and multiple sets of gas injection components for injecting gas into the mixture. The exhaust component is connected to the upper end of the vessel body and is used to discharge gas from the vessel body. The multiple sets of gas injection components cooperate to inject gas into the vessel body in sequence. The gas injection component includes multiple gas injection plates, and multiple gas injection holes are provided at intervals on the gas injection plates. The gas injection plates are connected to the inner surface of the bottom of the vessel body with a gap. The gas injection holes are opposite to the inner surface of the bottom of the vessel body, and the gas is injected into the vessel body through the gas injection holes on the gas injection plates.

[0006] Explanation: The injected gas is an inert gas.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, through the design of an injection plate and injection holes, allows gas to be injected into the reactor. The gas agitates the mixture of ultrapure water and ethylene glycol. The turbulence and shear force generated by the rising bubbles break the laminar boundary layer in the liquid. As the bubbles rise, a wake zone forms at their tails, where the turbulence intensity is much higher than the surrounding liquid, accelerating the penetration of ethylene glycol molecules into the ultrapure water. The omnidirectional upward movement of the bubbles covers the entire reactor, eliminating dead zones, reducing agitation time, and improving agitation efficiency. Furthermore, the gas agitation avoids mechanical contact with the mixture, preventing contamination, improving purity, and enhancing the quality of thermal management fluids for new energy vehicles. The inert gas agitation of the mixture... When the mixture is in use, a protective layer can be formed on the surface of the mixture to isolate oxygen and prevent ethylene glycol from oxidizing to produce organic acids, thereby extending the service life of the thermal management fluid for new energy vehicles. The vent is set opposite to the inner surface of the bottom of the vessel. Compared with the device that sets the vent opposite to the inner surface of the top of the vessel (that is, sets the vent on the upper surface of the gas injection plate), in this solution, the gas can form a group of fine bubbles. During the ascent, the gas drags the surrounding liquid and pushes the liquid to diffuse from the bottom to the surroundings. The liquid at the top replenishes the liquid downwards, forming a global circulation, which allows the liquid in each area of ​​the vessel to be fully mixed. If the gas is vented from the upper surface of the gas injection plate, it mainly stirs the area near the liquid surface and has a weaker stirring effect on the liquid at the bottom, resulting in insufficient mixing of the liquid at the bottom and the formation of sediment or stratification.

[0008] In a preferred embodiment of the present invention, the stirring assembly further includes an intelligent gas path controller and an air inlet pipe. The intelligent gas path controller is used to control the start and stop of gas injection for each group of gas injection components, as well as to control the gas injection volume. The gas injection component also includes a gas injection pipe, which is connected to the gas injection plate. One end of the intelligent gas path controller is connected to the air inlet pipe, and the other end is connected to the gas injection pipe.

[0009] Beneficial effects: The intelligent gas circuit controller can control the start and stop of gas injection of the corresponding gas injection components, and can allow multiple gas injection components to inject gas sequentially for gas agitation. Compared with continuous gas injection or gas injection and agitation by a single gas injection component, sequential gas injection of multiple gas injection components can form stratified or regional airflow disturbances, which can avoid flow field conflicts caused by simultaneous gas injection of all gas injection components, and can fully and uniformly agitate. Sequential gas injection is equivalent to intermittent energy input, which can reduce gas consumption and compressed air consumption compared with continuous gas injection.

[0010] In a preferred embodiment of this utility model, multiple connecting frames are provided between the gas injection pipes in each group of gas injection components, and the connecting frames are connected to the inner wall of the reactor.

[0011] Beneficial effects: During gas injection, the gas passes through the gas injection pipe, causing the pipe to vibrate. The connecting frame can increase the stability of the connection between the gas injection pipe and the vessel body, thereby preventing the vibration of the gas injection pipe from affecting the stability of the connection with the gas injection plate.

[0012] In a preferred embodiment of the present invention, the stirring assembly further includes multiple sets of limiting members for limiting the gas injection plate in the corresponding gas injection component, and the limiting members and the gas injection plate are detachably connected.

[0013] Beneficial effects: Compared to the fixed connection between the gas injection plate and the inner surface of the bottom of the vessel, such as welding, the setting of the limiting component allows the gas injection plate to be indirectly fixed to the inner surface of the bottom of the vessel. If the gas injection plate needs to be replaced, there is no need to use external force to remove the gas injection plate from the inner surface of the bottom of the vessel, reducing the impact on the inner surface of the bottom of the vessel, ensuring the integrity of the vessel, and improving the service life of the vessel.

[0014] In a preferred embodiment of this utility model, the limiting component includes a limiting rod, a first connecting rod, a telescopic rod, a second connecting rod, and a connecting cylinder. One end of the limiting rod is connected to the inner surface of the bottom of the vessel body, and the other end passes through the gas injection plate. The limiting rod is connected to the first connecting rod. One end of the telescopic rod is rotatably connected to the first connecting rod, and the other end is connected to the second connecting rod. The second connecting rod is rotatably connected to the connecting cylinder. The connecting cylinder can be threadedly connected to the end of the limiting rod that passes through the gas injection plate. After being threadedly connected to the limiting rod, the connecting cylinder can abut against the upper surface of the gas injection plate.

[0015] In this solution, during installation, the air injection plate is placed on the limiting rod, with one end of the limiting rod passing through the air injection plate. Since the first connecting rod and the telescopic rod are rotatably connected, rotating the telescopic rod allows the connecting cylinder to be positioned above the limiting rod. Then, since the connecting cylinder is rotatably connected to the second connecting rod, the connecting cylinder is threadedly connected to the upper end of the limiting rod, and the connecting cylinder abuts against the upper surface of the air injection plate, thus limiting the air injection plate.
