Description

Technical Field

[0001] This utility model relates to the field of vehicle engineering technology, and in particular to a wheel cooling device. Background Technology

[0002] In the field of modern transportation, vehicle performance and safety have always been the focus of attention. As an important component of a vehicle that directly contacts the road surface and undertakes key functions such as driving and braking, the stability of the wheel's working state has a crucial impact on the overall vehicle performance. During long-term driving, the friction between the wheel and the ground will cause the wheel temperature to rise rapidly. If heat dissipation is not timely, the gas inside the tire will expand due to heat, which may lead to excessive tire pressure, increase the risk of tire blowout, and seriously endanger driving safety.

[0003] Traditional wheel cooling methods mainly rely on simple natural convection, which slowly dissipates heat into the surrounding air through the metal material of the wheel itself. However, this method is extremely inefficient. In the face of modern high-speed and heavy-load traffic demands, natural convection is far from meeting the heat dissipation requirements of the wheels. Insufficient heat dissipation will lead to a decline in wheel performance and affect driving.

[0004] Therefore, there is an urgent need to provide a wheel cooling device to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a wheel cooling device.

[0006] To solve the above-mentioned technical problems, the present invention provides a wheel cooling device, including a wheel hub. Multiple heat-conducting fins are fixedly connected to the outer wall of the wheel hub. A mounting groove is formed near the center of the wheel hub's interior. Multiple ventilation ducts are formed inside the wheel hub. Cooling vents corresponding to the ventilation ducts are formed at both the front and rear ends of the wheel hub. Multiple placement slots are formed near the front and rear ends of the wheel hub's interior. A liquid cooling circulation mechanism is installed inside each placement slot. Multiple fixing screw holes are formed at both the front and rear ends of the wheel hub. A protective shell is rotatably connected to both the front and rear ends of the wheel hub.

[0007] The present invention is further configured such that a plurality of the heat-conducting sheets are circumferentially distributed on the outer wall of the hub in a uniformly spaced manner.

[0008] The above technical solution ensures that all parts of the outer wall of the wheel hub can be effectively cooled. During vehicle operation, the probability of heat generation in different parts of the wheel is relatively balanced. This distribution method allows heat to be evenly conducted to the heat-conducting fins, avoiding local overheating. By increasing the heat dissipation area, heat can be absorbed more quickly by the heat-conducting fins, which then evenly distribute the heat to the wheel hub. Heat dissipation is achieved through the heat dissipation channels of the wheel hub, thereby reducing the temperature of the gas inside the tire.

[0009] The present invention is further configured such that: all of the ventilation ducts extend radially from the center of the hub to the edge, and the inner walls of the ventilation ducts are all treated with a smooth finish.

[0010] Through the above technical solutions, this layout enables air to flow more efficiently from the center of the wheel hub to the edge. By utilizing the centrifugal force generated when the wheel rotates, the airflow in the channel is accelerated, improving heat dissipation efficiency. The radial distribution also ensures uniform heat dissipation in all parts of the wheel hub, avoiding local overheating. Furthermore, the smooth inner wall of the ventilation duct greatly reduces the frictional resistance during airflow.

[0011] The present invention is further configured such that the mounting slot is interconnected with multiple ventilation ducts.

[0012] Through the above technical solution, this interconnected structure greatly improves heat dissipation efficiency. The liquid storage tank in the placement slot absorbs a large amount of heat during operation, causing the temperature to rise. By connecting with the ventilation duct, the heat can be quickly transferred to the ventilation duct. Since the ventilation duct extends radially from the center of the wheel hub to the edge and has a smooth inner wall, it can utilize the centrifugal force generated when the wheel rotates and the oncoming airflow during vehicle movement to quickly carry away the heat. The air flows at high speed in the ventilation duct, continuously carrying away the heat transferred from the liquid storage tank, thereby efficiently reducing the temperature of the liquid storage tank and ensuring the cooling performance of the coolant.

[0013] The present invention is further configured such that: the liquid cooling circulation mechanism includes a liquid storage tank installed inside the placement tank, one end of the liquid storage tank is rotatably connected to a bottle stopper, and both ends of the liquid storage tank are respectively fixedly connected to a plurality of flexible liquid outlet pipes and a plurality of flexible liquid inlet pipes, each of the plurality of flexible liquid outlet pipes and the plurality of flexible liquid inlet pipes is equipped with a one-way valve, and the other end of each of the flexible liquid outlet pipes and the flexible liquid inlet pipes is equipped with a cooling pipe.

[0014] With the above technical solution, when the wheel hub is rotating, the coolant inside the higher cooling pipes will flow into the reservoir through the flexible outlet pipe under the influence of gravity. The one-way valve inside the flexible outlet pipe ensures that the coolant inside the flexible outlet pipe will not flow back. When the wheel hub rotates and the cooling pipes are in a lower position, the coolant inside the reservoir will flow into the cooling pipes through the flexible inlet pipe. The one-way valve inside the flexible inlet pipe ensures that the flowing coolant will not flow back into the reservoir. When the coolant level in the reservoir is low, the vehicle system will remind the driver to add coolant. Simply turn the bottle cap to open the reservoir and add coolant.

[0015] The present invention is further configured such that: the plurality of cooling pipes adopt a flat design, and the outer wall of the cooling pipes is attached to the inner wall of the corresponding placement groove.

[0016] Through the above technical solutions, the flat design greatly increases the surface area of ​​the cooling pipe. A larger surface area means that there is more contact area between the coolant and the external environment, thus enabling more efficient heat exchange.

[0017] The present invention is further configured such that: the flexible liquid outlet pipe is connected to the bottom of the corresponding cooling pipe, and the flexible liquid inlet pipe is connected to the top of the corresponding cooling pipe.

[0018] Through the above technical solution, the connection method of bottom liquid outlet and top liquid inlet makes the cooling pipe more evenly stressed. When the wheel rotates at high speed, the centrifugal force will act on the coolant and the cooling pipe.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model designs a liquid cooling circulation mechanism. When the wheel hub rotates, the coolant in the high-positioned cooling pipe flows into the storage tank through a flexible outlet pipe under gravity. A one-way valve prevents the coolant from flowing back into the cooling pipe. Meanwhile, the coolant in the storage tank flows into the low-positioned cooling pipe through a flexible inlet pipe, and the one-way valve again prevents the coolant from flowing back into the storage tank. This ensures the unidirectional and stable circulation of the coolant, allowing the entire liquid cooling system to work continuously and efficiently. With the help of gravity and the rotation of the wheel, the coolant can circulate naturally between the cooling pipe and the storage tank. This natural circulation method does not require additional power equipment, which not only reduces the system's energy consumption and cost, but also continuously transfers heat from the cooling pipe to the storage tank during the wheel's rotation, and then dissipates it through the ventilation duct, effectively reducing the temperature of the wheel hub.

[0021] 2. This utility model connects the mounting slot with multiple ventilation ducts through its design. The liquid storage tank in the mounting slot absorbs a large amount of heat during operation. By connecting with the ventilation ducts, the heat can be quickly transferred to the ventilation ducts. Since the ventilation ducts extend radially from the center of the wheel hub to the edge, they can utilize the centrifugal force generated when the wheel rotates and the oncoming airflow during vehicle movement to quickly carry away the heat. The air flows at high speed in the ventilation ducts, continuously carrying away the heat transferred from the liquid storage tank, thereby efficiently reducing the temperature of the liquid storage tank and ensuring the cooling performance of the coolant.

Detailed Implementation

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0030] Please see Figure 1 - Figure 4A wheel cooling device includes a wheel hub 1. Multiple heat-conducting fins 2 are fixedly connected to the outer wall of the wheel hub 1. These fins are evenly spaced and circumferentially distributed on the outer wall of the wheel hub 1. This even distribution ensures effective heat dissipation for all parts of the outer wall of the wheel hub 1. During vehicle operation, the probability of heat generation in different parts of the wheel is relatively even. This distribution method allows heat to be evenly conducted to the heat-conducting fins 2, avoiding localized overheating. By increasing the heat dissipation area, heat can be absorbed more quickly by the heat-conducting fins 2, which then evenly distribute the heat to the wheel hub 1. Heat dissipation is achieved through the ventilation ducts 4 of the wheel hub 1, thereby reducing the internal gas temperature of the tire. A mounting groove 3 is located near the center of the interior of the wheel hub 1. The mounting groove 3 is interconnected with multiple ventilation ducts 4. This interconnected structure greatly improves heat dissipation efficiency. A liquid storage tank 701 within the mounting groove 3 absorbs a large amount of heat during operation, causing its temperature to rise. Through its connection with the ventilation ducts 4, the heat can be quickly transferred to the ventilation ducts 4. The hub 1 extends radially from the center to the edge, and its inner wall is smooth. It can quickly carry away heat by utilizing the centrifugal force generated when the wheel rotates and the oncoming airflow during vehicle movement. The air flows at high speed in the ventilation duct 4, continuously carrying away the heat transferred from the liquid reservoir 701, thereby efficiently reducing the temperature of the liquid reservoir 701 and ensuring the cooling performance of the coolant. Multiple ventilation ducts 4 are provided inside the hub 1, all of which extend radially from the center of the hub 1 to the edge, and the inner walls of the ventilation ducts 4 are all smooth. This layout allows air to flow more efficiently from the center of the hub 1 to the edge. Utilizing the centrifugal force generated when the wheel rotates, the airflow in the channel is accelerated, improving heat dissipation efficiency. The radial distribution also ensures the uniformity of heat dissipation in all parts of the hub 1, avoiding local overheating. The smooth inner wall of the ventilation duct 4 can greatly reduce the frictional resistance during airflow. The front and rear ends of the hub 1 are provided with heat dissipation vents 5 corresponding to the ventilation ducts 4. Multiple placement slots 6 are provided inside the hub 1 near the front and rear ends.

[0031] like Figure 5 and Figure 6As shown, the interior of the placement tank 3 is equipped with a liquid cooling circulation mechanism 7. The liquid cooling circulation mechanism 7 includes a liquid storage tank 701 installed inside the placement tank 3. One end of the liquid storage tank 701 is rotatably connected to a bottle stopper 702. Multiple flexible liquid outlet pipes 703 and multiple flexible liquid inlet pipes 704 are fixedly connected to both ends of the liquid storage tank 701, respectively. Each of the multiple flexible liquid outlet pipes 703 and multiple flexible liquid inlet pipes 704 is equipped with a one-way valve 705. The other end of each flexible liquid outlet pipe 703 and flexible liquid inlet pipe 704 is equipped with a cooling pipe 706. The multiple cooling pipes 706 adopt a flat design and have a cooling effect. The outer wall of tube 706 fits into the inner wall of the corresponding placement slot 6. The flat design greatly increases the surface area of ​​the cooling tube 706. The larger surface area means that there is more contact area between the coolant and the external environment, thus enabling more efficient heat exchange. The flexible outlet tube 703 is connected to the bottom of the corresponding cooling tube 706, and the flexible inlet tube 704 is connected to the top of the corresponding cooling tube 706. The bottom outlet and top inlet connection method makes the cooling tube 706 more evenly stressed. When the wheel rotates at high speed, centrifugal force will act on the coolant and the cooling tube 706.

[0032] like Figure 5 and Figure 6 As shown, when the wheel hub 1 is rotating, the coolant inside the high-positioned cooling pipe 706 will flow into the reservoir 701 through the flexible outlet pipe 703 under the influence of gravity. The one-way valve 705 inside the flexible outlet pipe 703 ensures that the coolant inside the flexible outlet pipe 703 will not flow back. When the wheel hub 1 rotates and the cooling pipe 706 is in a low position, the coolant inside the reservoir 701 will flow into the cooling pipe 706 through the flexible inlet pipe 704. The one-way valve 705 inside the flexible inlet pipe 704 ensures that the flowing coolant will not flow back into the reservoir 701. When the coolant content in the reservoir 701 is low, the vehicle system will remind the driver to add coolant. Simply turn the bottle stopper 702 to open the reservoir 701 to add coolant.

[0033] like Figure 1 and Figure 2 As shown, the front and rear ends of the hub 1 are provided with multiple fixing screw holes 8, and the front and rear ends of the hub 1 are rotatably connected with protective shells 9.

[0034] In use, during the rotation of the wheel, a large amount of heat is generated due to continuous friction. At this time, the coolant inside the high-positioned cooling pipe 706 flows into the reservoir 701 through the flexible outlet pipe 703 under the influence of gravity. The reservoir 701 absorbs a large amount of heat, causing its temperature to rise. By connecting to the ventilation duct 4, the heat can be quickly transferred to the ventilation duct 4. Since the ventilation duct 4 extends radially from the center of the wheel hub 1 to the edge and has a smooth inner wall, it can quickly dissipate the heat by utilizing the centrifugal force generated when the wheel rotates and the oncoming airflow during vehicle movement. As air flows at high speed through the ventilation duct 4, it continuously carries away the heat transferred from the reservoir 701, thereby efficiently reducing the temperature of the reservoir 701. When the wheel hub 1 rotates, causing some of the cooling pipes 706 to be in a lower position, the coolant that has completed heat exchange inside the reservoir 701 will flow into the cooling pipes 706 through the flexible inlet pipe 704 to replenish the coolant in this part of the cooling pipes 706, making it easier for the cooling pipes 706 to cool the wheel hub 1. When the coolant content inside the reservoir 701 is low, the vehicle system reminds the driver to open the reservoir 701 by turning the bottle stopper 702 to replenish the coolant.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
