Problems solved by technology

When the temperature of the brake disc rises to a certain level, the brake heat will decline when the car is braking, which will affect the braking effect.
In the prior art, in order to reduce the phenomenon of vehicle thermal decay, automobile brake manufacturers use hollow brake discs or drill holes in the brake discs for heat dissipation, but these methods cannot be used under continuous long-term braking conditions. The temperature of the brake disc drops instantly, which seriously affects the braking effect

Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with accompanying drawing, as Figure 1-2 Shown: a high heat dissipation brake disc, including a disc body 1, the side wall of the disc body is provided with an annular opening groove 2, and a plurality of self-excited oscillation flow heat pipes 3 are arranged in the opening groove, and the self-excited oscillation The two ends of the flow heat pipe are respectively connected to the top and bottom of the open groove. A plurality of cavity-shaped grids 5 are arranged in the self-excited oscillating flow heat pipe along the pipe extending direction, and fixed particles 6 are arranged in the grid. During the braking process, the friction between the bottom of the disc body and the brake generates heat. On the one hand, the heat can be dissipated through the open groove. On the other hand, the self-excited oscillating flow heat pipe is encapsulated with a working medium, and the working medium forms a pl...

Abstract

The invention discloses a high heat-dissipation brake disc, which comprises a disc body. Annular opening slots are formed in side walls of the disc body; a plurality of selfexcited oscillating-flow heat pipes are arranged in the opening slots; and two ends of the selfexcited oscillating-flow heat pipes are connected with the top parts and the bottom parts of the opening slots. The high heat-dissipation brake disc with the structure has the advantages of rapidness and promptness in cooling during a brake process.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a high heat dissipation brake disc. Background technique [0002] The brake disc is an important part of the car when braking. The quality of the car's braking performance directly affects the driving safety of the car. Especially for large-scale heavy-duty vehicles, due to their large inertia when braking, the brakes will rub against the brake disc, and the temperature of the brake disc will rise rapidly. When the temperature of the brake disc rises to a certain level, the brake heat decline phenomenon will occur when the car is braking, which will affect the braking effect. In the prior art, in order to reduce the phenomenon of vehicle thermal decay, automobile brake manufacturers use hollow brake discs or drill holes in the brake discs for heat dissipation, but these methods cannot be used under continuous long-term braking conditions. The temperature of the brake disc drops instan...
