Phase change energy storage cooling device of disc brake

Abstract

The invention discloses a phase change energy storage cooling device of a disc brake, comprising a heat pipe heat transfer module and a phase change material energy storage module which are arranged on a disc brake body. A heat pipe technology is used to realize rapid export of the temperature of a static disc core plate of the disc brake; heat absorption and storage are realized by using a phase-change material phase-change energy storage technology; a shell and fins are designed through aluminum metal; and natural convection heat exchange with a power cabin environment is carried out. On the basis of an original disc brake, the disc brake is designed based on the heat pipe technology and the phase change energy storage technology, a phase change material cools a condensation section of the heat pipe by means of the heat absorption, energy storage and heat release solidification characteristics of the phase change material, and the phase change material conducts heat through the shell and conducts natural convection heat exchange with the power cabin environment, without needing forced convection heat exchange and additional work doing; and compared with a traditional disc brake, the disc brake has the advantages that the temperature of key positions such as the friction surface of the disc brake for circulating braking can be reduced, and the heat fading resistance is enhanced.

Description

technical field [0001] The invention relates to the field of heat control, in particular to a phase-change energy storage cooling device for a disc brake. Background technique [0002] The scene environment with high-temperature disc brake conditions for cyclic braking usually occurs during the travel of tanks and armored vehicles. With the iterative update of tanks and armored vehicles, more complex systems and functions have been added to the tank design, significantly increasing the The weight of the tank, generates a lot of heat. It is particularly important to enhance the thermal fading resistance of the disc brake and improve the braking performance, so the thermal control of the brake system has also received special attention. Document 1 (Q.F.Jian, Y.Shui, Numerical and experimental analysis of transient temperature field of ventilated disc brake under the condition of hard braking[J], Int.J.Therm.Sci.122(2017)115–123.) research shows that the system During the hea...

In Document 2, the heat pipe is buried on the inner surface of the brake disc, which improves the uniformity of temperature, but only uses the rapid heat transfer characteristics of the heat pipe to distribute the heat evenly, and does not export it to the outside of the brake, and its heat dissipation effect is very limited
