A structure for cooling an exhaust manifold, comprising:
- a duct cooling the exhaust manifold by using traveling wind or fan wind;
- a duct opening and closing portion mounted at a rear end of the duct to open or close the duct for cooling an exhaust manifold;
- and
- an exhaust manifold protector disposed at a lower end of the duct for cooling the exhaust manifold and enclosing the exhaust manifold,
- wherein the duct includes:
- a body portion into which the traveling wind or fan wind is introduced;
- and
- a hollow-shaped heat insulation portion having an upper end mounted at a rear end of the body portion and a lower end opened toward an upper surface of the exhaust manifold protector,
- wherein the exhaust manifold protector includes:
- a cooling hole formed on an upper surface of the exhaust manifold;
- and
- a guide portion protruding upwardly from an outer circumferential surface of the cooling hole,
- wherein an upper end of the guide portion and the lower end of the heat insulation portion are connected to each other.
