The brake disc is inside to be hollow, and the hollow cross -section is the L type, and heat pipe evaporation zone and heat pipe condensation segment constitute the L type, add working medium with the inside cavity of L type to sealed after the evacuation, radiating fin is welded to the outside of heat pipe condensation segment. When the vehicle took place the braking action or brakies the action for a long time, brake block and brake disc friction, production of heat, heat passed through the inside working medium of brake disc heating cavity, and the condensation segment is reachd to working medium evaporation back, and radiating fin through the condensation segment gives off the heat to the atmosphere in, reduced the temperature of brake disc, reduced braking heat fading phenomenon, improved driving safety.

Description

A kind of hot tube automobile brake disc cooling unit

Technical field

The utility model relates to a kind of hot tube automobile brake disc cooling unit, utilizes heat pipe principle, is cooled fast by brake disc, belong to automobile equipment technical field.

Background technique

Braking is one of most important parts of automobile, and the quality of braking ability, directly affects traffic safety.Automobile is when braking for a long time, and brake disc temperature is very high, at night, even can see that brake disc sends red as fire color.In this case, be very easy to produce braking failure.At rugged mountain path, when running into long and steep downgrade, this situation is abnormally dangerous.Even if when routine use service brake, also there will be braking heat fade phenomenon.

At present, vehicle is for reducing heat fade phenomenon, and automobile brake producer generally adopts hollow brake disc, punches on brake disc, with increasing heat radiation area, reduces heat fade phenomenon.Also there are some large vehicles, adopt water spray projector system, brake disc is cooled.Water spray easily brings other negative effect to brake system, as water may cause brake system to get rusty, corrode, Properties of Friction Materials such as to go down at the phenomenon.

Model utility content

Model utility object: for above-mentioned existing Problems existing and deficiency, the object of a kind of hot tube automobile brake disc of the utility model cooling unit reduces the temperature of brake disc, prevent brake disc temperature too high and the braking failure that causes, thus the traffic accident produced.

technological scheme:a kind of hot tube automobile brake disc cooling unit, comprises brake disc (1), heat pipe evaporator section (2), radiating fin (3), heat pipe condenser section (4);

Brake disc (1) inside is hollow, hollow cross section is L-type, and heat pipe evaporator section (2) and heat pipe condenser section (4) form L-type, and L-type internal cavities is added working medium, and sealed after being vacuumized, the outside weldings radiating fin (3) of heat pipe condenser section (4).

Described radiating fin (3) adopts aluminium, and is uniformly distributed in circumference, and welding procedure adopts laser bonding.

Described heat pipe evaporator section (2) is positioned at brake disc corresponding to brake block (1) internal cavities position, and heat pipe condenser section (4) is positioned at internal cavities position corresponding to brake disc (1) center.

Described brake disc (1) is after gray cast iron casting, then fine finishing, and the brake disc of the present utility model difference maximum with traditional brake disc is brake disc inside is cavity structure, and cavity formation heat pipe, inside is filled with working medium.

Described heat pipe evaporator section (2) is brake disc internal cavities, is positioned at the internal cavities that the region of brake block work is corresponding.

Described radiating fin (3) is made up of aluminium flake, and size is even, and circumference is evenly distributed, and utilizes laser welding technology to be welded on heat pipe condenser section (4) around.

Described heat pipe condenser section (4) is brake internal cavities, is positioned at the internal cavities that brake disc central position is corresponding.Heat pipe condenser section (4) and heat pipe evaporator section (2) are the internal cavity structures of L-type at brake disc (1) Inner Constitution section, as shown in Figure 1, the top that pipe evaporator section (2) is L-type, L-type is the bottom of L-type, and heat pipe condenser section (4) and heat pipe evaporator section (2) UNICOM.

Working principle: hot tube automobile brake disc cooling unit, be heat tube structure by brake disc (1) indoor design, when braking occurs vehicle, brake block and brake disc (1) rub and produce a large amount of heats, and heat is by brake disc (1), the working medium that heat hot brake disc (1) is inner, after working medium evaporation, to heat pipe condenser section (4), heat pipe condenser section (4) installs radiating fin (3), heat can be passed rapidly, reduce the temperature of brake disc (1).

Vehicle is when motion state, brake disc (1) is in rotation, under the influence of centrifugal force, the inner working medium of brake disc (1) is distributed in the most edge in brake disc (1) inside, the brake disc (1) being just in time positioned at brake block corresponding position is inner, this position is the place that in brake process, heat is maximum, the heat that braking produces passes to working medium rapidly, working medium is evaporated, according to heat energy basic principle, arrive heat pipe condenser section (4) after working medium evaporation, heat pipe condenser section (4) is provided with radiating fin (3), distributes heat to fast in air.Further, in the process of moving, radiating fin (3), along with wheel fast rotational together, dispels the heat vehicle more effectively.

When vehicle is in halted state, under gravity, working medium rests on the bottommost of brake disc (1), if brake disc (1) is overheated, heat energy also can heating working medium, arrive heat pipe condenser section (4) after working medium evaporation, distribute heat in air through radiating fin, play brake disc (1) refrigerating function.

beneficial effect:the utility model has the following advantages.

(1) the utility model adopts brake disc inside to be cavity structure, and internal cavities forms heat pipe, can be distributed by the heat of brake disc fast, effectively improve brake security, reduces braking heat fade.
