Embodiment Construction

[0040] The heat pipe used for automobile brake pads provided by the present invention can quickly dissipate heat and cool down, and at the same time generate directional thrust. The evaporation end is fixed on the steel back side of the brake pad. The shape of the heat pipe is I-shaped, and copper is used as the shell material. , the evaporating end and the condensing end are elliptical cylindrical box-shaped cavities, the upper surface of the evaporating end and the upper surface of the condensing end are connected by a circular connecting pipe with a diameter of 15mm, and a liquid-absorbing core is arranged on the inner side of the connecting pipe , is an axial groove composed of multiple Ω shapes, the groove depth is 0.6mm, and the aspect ratio is 1.5:1. The evaporating end has a hole for the insertion and tight welding of the perfusion tube. The perfusion tube is sealed by cold welding and then welding. The inner diameter is 1 / 16 inch and the outer diameter is 1 / 4 inch.

Abstract

The invention relates to a heat pipe radiation and thrust generation device and a production method thereof, which not only can be used for rapidly transmitting heat generated in a braking process outside to rapidly radiate heat for cooling, but also can be used for generating the directional thrust simultaneously while radiating the heat. An evaporation end and a condensation end of the heat pipe are cylindroid box-shaped cavities which are connected by a round connection pipe. A liquid suction core is arranged at the inner side of the connection pipe, the evaporation end is provided with a hole through which an infusion pipe is conveniently inserted and tightly welded, and the infusion pipe is sealed by a way of cold-welding sealing at first and welding later. The invention further provides a production method of a heat pipe applied to an automotive brake pad. The method comprises the steps of: material selecting, mechanical processing, cleaning, assembling, leakage detecting, vacuumizing, working medium injecting, sealing-in and inspecting. By applying the heat pipe to a brake pad heat radiator, not only can the problem about the heat fading of the brake pad be effectively solved, but also the new direction for developing a bake pad heat radiator is provided.

Description

technical field [0001] The invention relates to a heat pipe for automobile brake pads, in particular to a heat pipe for automobile brake pads capable of dissipating heat and generating thrust and a preparation method thereof. Background technique [0002] Automobile braking is achieved through the friction between brake pads and brake discs or brake drums. The process of automobile braking is the process of converting kinetic energy into frictional heat energy. During the braking process of the car, especially during emergency braking at high speed, a large amount of heat will be generated due to friction, and the instantaneous temperature of the brake pads will rise sharply, which can reach 300-400°C. Under the physical and chemical effects, the friction of the brake pads will The sudden change in the properties of the material will cause the coefficient of friction to decrease or fluctuate violently, which will significantly increase the thermal degradation of the brake pa...
