Abstract

A structure of a brake-cooling duct, which is disposed at one side of an intercooler tank to cool a brake disc using air may include the brake-cooling duct has an air movement channel and a through-hole formed in a side surface thereof to expose the channel to an outside, wherein the brake-cooling duct is disposed close to one side of the intercooler tank so that an external surface of the intercooler tank is exposed to the channel via the through-hole, allowing the air introduced into the channel to be brought into contact with the external surface of the intercooler tank, and thereafter be discharged rearward thereof.

Claims

1. A structure of a brake-cooling duct, the brake-cooling duct being configured to cool a brake disc by rearwardly discharging air introduced from a front side thereof and being mounted to be disposed at a first side of an intercooler tank, the structure including:

the intercooler tank; and

the brake-cooling duct having an air movement channel defined therein and a through-hole formed in a side surface thereof to expose the channel to an outside of the side surface,

wherein the brake-cooling duct is disposed at the first side of the intercooler tank wherein an external surface of the intercooler tank is exposed to the channel via the through-hole, allowing the air introduced into the channel to be brought into contact with the external surface of the intercooler tank, and thereafter be discharged rearward thereof.

2. The structure according to claim 1, wherein the brake-cooling duct is provided with a plurality of bosses at a front side of the through-hole to create an eddy during air movement.

3. The structure according to claim 2, wherein the bosses are disposed to form a matrix.

4. The structure according to claim 1, wherein the external surface of the intercooler tank, on which the through-hole is located, is provided with a cooling fin to increase a contact area with the air that passes through the channel.

5. The structure according to claim 4, wherein the cooling fin includes at least two cooling fins, and the at least two cooling fins are formed in parallel to each other along a direction in which the channel is open to guide a flow of the air.

6. The structure according to claim 1, wherein the external surface of the intercooler tank that faces the brake-cooling duct and the side surface of the brake-cooling duct that faces the intercooler tank are inclined by an angle at which an upper surface of the intercooler tank and an upper surface of the brake-cooling duct are in parallel to each other.

7. The structure according to claim 1, wherein one of the intercooler tank and the brake-cooling duct is provided with a tip portion for insertion of a bolt, and the intercooler tank and the brake-cooling duct are fixedly coupled to each other by the bolt inserted into the tip portion.

8. The structure according to claim 1, wherein the intercooler tank is formed of a metal material and the brake-cooling duct is formed of a material having a thermal conductivity lower than that of the material of the intercooler tank.
