Technical Field

[0001] The present application relates to the technical field of brake cooling, and in particular to a high-efficiency automobile brake cooling system. Background Art

[0002] In the context of the rapid development of the new energy vehicle industry, especially electric vehicles, the performance of the braking system directly affects the safety and driving experience of the vehicle. In the case of continuous or high-intensity braking, if the heat generated by the brakes cannot be dissipated in time, it will lead to a decrease in braking performance or even brake failure, posing serious safety hazards. At present, air cooling is the most common brake cooling method and is widely used due to its simple structure and low cost. However, the cooling efficiency of air cooling is insufficient in high temperature environments or under heavy braking loads, especially in high temperatures in summer or under continuous braking conditions, the limitations of the air cooling system are more obvious.

[0003] Currently, most automotive brake systems rely on natural air cooling or forced air cooling for cooling. Natural air cooling relies on airflow when the vehicle is moving to dissipate heat, while forced air cooling uses electric fans to enhance air flow.

[0004] These methods are effective for low-speed or intermittent braking, but when braking frequently at high speeds or continuously in high-temperature environments, the efficiency of the air cooling system is limited by the ambient temperature, air flow rate, and the surface area of ​​the brake disc in contact with the air. It is often difficult to provide sufficient cooling effect, reducing the cooling efficiency of the brake system. Summary of the invention

[0005] The purpose of this application is to solve the problem that when braking frequently at high speed or continuously in a high temperature environment, the efficiency of the air cooling system is limited by the ambient temperature, air flow rate and the surface area of ​​the brake disc in contact with the air, which often makes it difficult to provide sufficient cooling effect and reduces the cooling efficiency of the brake system. This application provides a high-efficiency automobile brake cooling system.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions: A high-efficiency automobile brake cooling system comprises a fixed surface plate, one end of the fixed surface plate is fixedly connected to a friction surface plate, a flange connecting shaft is fixedly inserted between the fixed surface plate and the friction surface plate, an internal circulation flow channel is provided inside the fixed surface plate, both ends of the internal circulation flow channel are provided with drainage port 1, one end of the flange connecting shaft is provided with drainage port 2 connected with drainage port 1, one end of the flange connecting shaft is symmetrically fixedly connected to a sealing shaft connector, one end of the sealing shaft connector is rotatably connected to a circulation pipe, two of the circulation pipes are respectively connected to two drainage ports 1 through two drainage ports 2, a circulation component is installed at one end of the sealing shaft connector, a heat sink is installed on one side of the fixed surface plate, a heat sink is provided inside the heat sink, a ventilation groove is provided at one end of the heat sink, one end of the ventilation groove is fixedly connected to a ventilation pipe, one end of the ventilation pipe is fixedly connected to a brake air duct pipe, and the output end of the brake air duct pipe faces one side of the friction surface plate.

A ventilation pipe 12 is fixedly connected to one end of the ventilation groove 11, and a brake air duct pipe 13 is fixedly connected to one end of the ventilation pipe 12, and the output end of the brake air duct pipe 13 faces one side of the friction surface plate 2; Among them, the circulation component includes an outlet pipe 14 rotatably connected to one end of a sealed shaft connector 7, and an inlet pipe 15 rotatably connected to one end of the other sealed shaft connector 7, the input end of the outlet pipe 14 is connected to the output end of the heat dissipation channel 10, and the output end of the inlet pipe 15 is fixedly connected to a circulation pump 16, and the output end of the circulation pump 16 is connected to the input end of the heat dissipation channel 10.

[0031] When in use, firstly, the brake air duct 13 is connected to the front air intake grille, so that when driving, the air is accelerated to pass through the brake air duct 13 and flow to the surface of the friction surface plate 2, and when braking, the flowing air can exchange heat and cool down with the surface of the friction surface plate 2, and at the same time, the circulating pump 16 is started to pump the coolant inside the inner circulation channel 4 to circulate out through the drainage port 5 into the inside of the circulation pipe 8, and then introduced into the inside of the heat dissipation channel 10 through the introduction pipe 15.

[0037] During use, when the brake air duct pipe 13 is set to guide the air flow to the surface of the friction plate 2 through the front air intake grille, the air is intercepted and filtered by the filter net 23, so that foreign matter in the air is intercepted outside the brake air duct pipe 13, reducing the jamming inside the brake air duct pipe 13 and improving the practicality of the device.
