Abstract
The invention relates to an automotive brake structure, in particular to automotive brake heat dissipating device. The automotive brake heat dissipating device comprises a heat dissipating sheet and a heat dissipating plate. The device is characterized in that a synthetic jet flow heat dissipating device is fixed on a brake block which is bored at a nozzle of the synthetic jet flow heat dissipating device. The device provided by the invention has the beneficial effects that 1, the heat dissipating sheet can be continuously dissipated by virtue of a high heat dissipating property of the synthetic jet flow heat dissipating device; 2, the synthetic jet flow heat dissipating device is small in size, and the thickness is only several millimeters, so that the operating property of a wheel is finitely affected; and 3, a synthetic jet flow device module is long in service life, low in power supply voltage, convenient to detach and convenient to maintain.
Description
Technical field
The present invention relates to a kind of braking automobile chip architecture, more particularly to a kind of automobile brake sheet heat abstractor.
Background technology
Brake block is critically important stop component, and in brake, brake block is compressed on brake disc and produces friction to reach
The purpose of brake, but substantial amounts of heat can be also produced simultaneously, when heat oversteps the extreme limit, brake pad is just easily deformed, and makes brake
It is extremely unstable, it is prone to accidents.
The automobile brake sheet for using at present is divided into actively heat exchange and passive heat exchange two parts.Automobile brake sheet actively lead by heat exchange
If brake block water-cooled or oil cooling exchange heat, this radiating mode heat exchange efficiency is high, but structure bulky, influence the operation of wheel
Performance.Passively heat exchange is mainly brake block by structure improvement to automobile brake sheet, and back increases the heat exchange of the construction forces such as fin, this
Simple structure is planted, it is easy to use, have the disadvantage that radiating efficiency is poor, particularly under long-time braking conditions, brake pad is just easy to become
Shape.
Synthesizing jet-flow excitor (Synthetic jet actuator) is proposed in recent years in the world a kind of brand-new
Flow control technique, its general principle is to set the annular seal space in (or hole) of cracking in flowing wall, using shaking for piezoelectric
It is dynamic, a series of successively abducent unsteady vortex pairs (or collar vortex) are produced at gap, its effect to main flow is similar to
In one jet, so as to reach the purpose of active Flow Control.
The content of the invention
In order to solve the technological deficiency of above-mentioned radiator structure, the present invention uses synthesizing jet-flow device radiation, reaches brake block
Radiating purpose.
A kind of automobile brake sheet heat abstractor, including fin and cooling plate structure, it is characterised in that：Synthesizing jet-flow radiates
Device is fixed on brake block, and brake block is in synthesizing jet-flow heat abstractor nozzle perforate.
The synthesizing jet-flow heat abstractor spout and brake block position of opening are corresponded, and aperture is identical, brake block
The rubbing surface of perforate is in indent funnel-form, and when brake disc is contacted with brake block, perforate keeps 2-4mm with contact surface.
The synthesizing jet-flow heat abstractor includes cavity, spout and vibrating diaphragm, and spout is in the top of cavity, vibrating diaphragm
In the lower section of cavity.
The nozzle diameter 0.2-2mm of the synthesizing jet-flow heat abstractor, cavity diameter 25-40mm, inside cavity is highly
1.5-5mm。
The vibrating diaphragm vibration frequency 0.001-5KHZ of the synthesizing jet-flow heat abstractor.
Beneficial effect of the present invention：1. the high-cooling property of synthesizing jet-flow device can be continuously fin radiating；2. synthesis is penetrated
Stream device radiation piece small volume, thickness only has several millimeters, and the handling influence on wheel is limited；3 synthesizing jet-flow device moulds
Block long lifespan, supply voltage is low, and convenient dismounting, is easy to maintenance.

Specific embodiment
Fig. 1 and Fig. 2 are respectively brake block outer surface and inner surface structure, during braking, the friction brake disk 3 of brake block 1.Synthesis
Jet heat abstractor 2 is fixed on the outer surface of brake block 1, the perforate at the spout 22 of synthesizing jet-flow heat abstractor 2 of brake block 1.
As shown in figure 4, the rubbing surface of brake block perforate be in indent funnel-form, when brake disc is contacted with brake block, perforate and
Contact surface keeps 2-4mm.During braking automobile, brake block 1 and brake disc friction, synthesizing jet-flow heat abstractor 2 are started working.
As shown in figure 3, the nozzle diameter 0.2-2mm of synthesizing jet-flow heat abstractor, cavity diameter 25-40mm, inside cavity
Height 1.5-5mm.Vibrating diaphragm 23 shakes in the lower section of cavity 21, and vibration frequency control is empty in 0.001-5KHZ, cavity 21
Gas sprays with vibrations from spout 22, the perforate that turbulent gases pass through brake block 1, is ejected into brake plate surface, plays instantaneous drop
The effect of temperature.
After end of braking, synthesizing jet-flow heat abstractor 2 is stopped.
