Description

Technical Field

[0001] The utility model relates to the technical field of vehicle brakes, in particular to a disc brake water-cooling heat dissipation system. Background Art

[0002] The disc brake system is often applied to the brake systems of various vehicles. It consists of a brake disc connected to the wheel and brake calipers at the edge of the disc. When braking, high-pressure brake fluid pushes the brake pads to clamp the brake disc, thereby generating a braking effect. Generally, continuous braking of the disc brake system is likely to cause the temperature of the brake calipers to be too high, resulting in a weakening or failure of the braking effect, and posing potential safety hazards.

[0003] Therefore, ventilated disc brakes have emerged. The ventilated disc brakes have many circular ventilation holes drilled on the disc surface, or ventilation grooves cut on the end surface of the disc, or rectangular ventilation holes prefabricated. Although the heat transfer effect of the ventilated disc brakes is better than that of ordinary disc brakes due to the action of air flow, for large vehicles, a large amount of heat is generated during the braking process. The heat dissipation capacity of this ventilated heat dissipation is limited, and it cannot quickly reduce the heat of the outer ring of the disc, making it difficult to meet the heat dissipation requirements. Moreover, after long-term use, a large amount of dust and debris accumulates in the heat dissipation chamber, reducing the heat dissipation efficiency of the heat dissipation chamber, shortening the service life of the disc, and even leading to brake failure, reducing vehicle control and affecting safety.

[0025] Embodiment 1:

[0026] A disc brake water-cooling heat dissipation system provided in this embodiment, as Figures 1-5 shown, includes a disc brake assembly 3, a water-cooling base 1, and a semiconductor refrigeration sheet 2.

[0028] Among them, the water-cooling base exchanges heat through the flow of cooling water to cool the disc brake assembly 3 and the thermoelectric cooler 2. The thermoelectric cooler 2 is a single-piece cooler, which is composed of two ceramic sheets with N-type and P-type semiconductor materials in the middle. This semiconductor element is connected in series in the circuit.

[0029] In this embodiment, the thermoelectric cooler 2 is attached to the disc brake assembly 3, so as to cool the disc brake assembly 3 through the thermoelectric cooler 2, and the water-cooling base 1 is arranged to cool the thermoelectric cooler 2 and the disc brake assembly 3, enabling the thermoelectric cooler 2 to dissipate heat effectively, improving the cooling efficiency of the thermoelectric cooler 2 for the disc brake assembly 3, and at the same time, the water-cooling base 1 can further cool the disc brake assembly 3.

[0030] In this embodiment, the disc brake water-cooling heat dissipation system is based on the fact that heat exhaustion may occur in the existing disc brake assembly 3. The water-cooling base 1 and the thermoelectric cooler 2 are redesigned and added on the original structure. By using the water-cooling base 1 and the thermoelectric cooler 2 in combination, the disc brake assembly 3 is effectively cooled, and the heat dissipation efficiency of the disc brake assembly 3 is improved, thus effectively solving the safety hazard that the braking effect fails due to overheating of the brake caliper.

[0031] As a preferred embodiment, an installation groove 311 is provided on the disc brake assembly 3. The thermoelectric cooler 2 is installed in the installation groove 311 and its two sides are respectively connected to the refrigeration circuit through wires. The refrigeration circuit provides direct current for the thermoelectric cooler 2. Among them, the shape of the installation groove 311 is adapted to the shape of the thermoelectric cooler 2, so as to effectively limit the thermoelectric cooler 2. The shape of the thermoelectric cooler 2 is changed according to the requirements of the caliper, and the shapes include square, circular and irregular shapes.

[0032] The periphery of the water-cooling base 1 is connected to the periphery of the installation groove 311 through a connecting piece. Among them, the connecting piece can be a bolt for convenient disassembly and maintenance.

[0033] As a preferred embodiment, as Figure 2 and Figure 4 shown, a limiting block 312 is provided on the disc brake assembly 3. The limiting block 312 is arranged on the edge of the installation groove 311. A limiting groove 124 adapted to the limiting block 312 is provided on the water-cooling base 1. The limiting groove 124 is engaged with the limiting block 312, so that the connection between the disc brake assembly 3 and the water-cooling base 1 is more reliable. The thermoelectric cooler 2 is clamped in the installation groove 311, so that the disc brake assembly 3 and the water-cooling base 1 can be closely attached to both sides of the thermoelectric cooler 2, enabling the water-cooling base 1 to effectively cool the thermoelectric cooler 2 and the disc brake assembly 3.

[0034] As a preferred embodiment, as Figure 2 and Figure 3As shown, a water cooling chamber 121 is provided in the water cooling seat 1 , and a water inlet and a water outlet are respectively provided on the water cooling seat 1 , the water inlet and the water outlet are respectively connected to a water inlet pipe 13 and a water outlet pipe 14 , and the water inlet pipe 13 and the water outlet pipe 14 are both connected to the water cooling chamber 121 .

[0035] The cooling water in this embodiment enters the water cooling chamber 121 of the water cooling seat 1 from the water inlet pipe 13 and the water inlet, and flows out from the water outlet and the water outlet pipe 14 after heat exchange with the semiconductor cooling plate 2 and the disc brake assembly 3 through the water cooling seat 1. The water flow can also flow into the water cooling chamber 121 from the water outlet and the water outlet pipe 14, and flow out from the water inlet pipe 13 and the water inlet. The cooling water is introduced as the coolant, and other fluid media can also be introduced as the coolant.

[0036] As a preferred embodiment, a drainage block 122 is provided in the water cooling chamber 121. The drainage block 122 is smoothly connected to one side of the water cooling chamber 121 and extends to the opposite side. The water inlet and the water outlet are respectively provided on both sides of the drainage block 122. The drainage block 122 plays the role of diverting and diverting the inflow and outflow water, so that the water flows around the drainage block 122 and flows around the drainage block 122. The drainage block 122 also plays the role of disturbing the flow, thereby improving the heat exchange effect.

[0037] As a preferred embodiment, the water cooling seat 1 includes a base 12 and a cover plate 11, a water cooling chamber 121 is arranged on the base 12 and has an opening, and the cover plate 11 is sealed on the opening of the water cooling chamber 121. A limit groove 124 adapted to the limit block 312 is arranged on the side of the base 12 away from the cover plate 11. The base 12 can be made of a metal material with good thermal conductivity. The cover plate 11 is connected to the disc brake assembly 3 by bolts passing through the cover plate 11 and the base 12. The cover plate 11 can be separated from the base 12 to open the water cooling chamber 121, so as to facilitate cleaning of the water cooling chamber.

[0038] As a preferred embodiment, a sealing groove 123 is provided on the base 12, and the sealing groove 123 is provided along the periphery of the water cooling chamber. A sealing ring 15 is provided in the sealing groove 123, and the sealing groove 123 limits the sealing ring 15. When the cover plate 11 covers the opening of the water cooling chamber 121, the sealing ring 15 is squeezed. By providing the sealing ring 15, the sealing performance of the cover plate 11 to the water cooling chamber 121 is further increased. When the heat dissipation speed is increased, the water cooling chamber 121 can withstand a higher water pressure, and the flow rate of the water in the water cooling chamber 121 can be increased.

[0039] As a preferred embodiment, the disc brake assembly 3 includes a first brake caliper 31 and a second brake caliper 36. A first piston 32 is disposed within the first brake caliper 31, and a second piston 35 is disposed within the second brake caliper 36. A first brake pad 33 and a second brake pad 34 are respectively disposed on one side of the first brake caliper 31 and the second brake caliper 36 that are close to each other. The first brake pad 33 and the second brake pad 34 are connected by a return spring 37. During braking, high-pressure brake fluid pushes the first brake pad 33 through the first piston 32 and pushes the second brake pad 34 through the second piston 35, causing the first brake pad 33 and the second brake pad 34 to move towards each other and clamp the brake disc to generate a braking effect. When in a non-braking state, the return spring 37 moves the first brake pad 33 and the second brake pad 34 in a direction away from each other to return to their original positions. The disc brake assembly 3 can be an existing disc brake system.

[0040] The water-cooling seat 1 and the semiconductor refrigeration sheet 2 are connected to the side of the first brake caliper 31 and / or the second brake caliper 36 that are away from each other. The water-cooling seat 1 and the semiconductor refrigeration sheet 2 can be simultaneously disposed on the side of the first brake caliper 31 and the second brake caliper 36 that are away from each other, or can be only disposed on one side of the first brake caliper 31 or one side of the second brake caliper 36. The specific usage situation depends on the vehicle model to be installed. If there is sufficient space on the outer side of the wheel hub, the water-cooling seat 1 and the semiconductor refrigeration sheet 2 can be installed on the sides of the first brake caliper 31 and the second brake caliper 36 that are away from each other to cool the first brake caliper 31 and the second brake caliper 36 simultaneously.

[0041] In the disc brake water-cooling and heat-dissipating system of this embodiment, after the refrigeration circuit of the water-cooling seat and the semiconductor refrigeration sheet is energized, direct current is provided to the semiconductor refrigeration sheet to turn on the refrigeration effect, which can achieve the purpose of dissipating heat from the brake caliper. At the same time, coolant is introduced into the water-cooling seat to cool the semiconductor refrigeration sheet and the brake caliper simultaneously, generating a heat-dissipating effect. By combining the water-cooling seat and the semiconductor refrigeration sheet to dissipate heat from the brake caliper, this can prevent the brake caliper from overheating and causing the braking effect to fail, thereby greatly improving the safety guarantee for users.

[0042] The disc brake water-cooling and heat-dissipating system of this embodiment can not only be used for the brake calipers of automobiles, but also for the brake calipers of motorcycles and other vehicles to improve the heat-dissipating efficiency.

[0043] The above is only the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can make several deformations and improvements without departing from the creative concept of the present invention, and all should be covered within the protection scope of the present invention.
