PURPOSE: A cooling apparatus of a synthetic resin intake manifold is provided to improve efficiency of an engine by elevating the charging ratio of air by falling the temperature of a synthetic resin intake manifold, to improve stiffness by connecting respective runner to each other and to buffer noise and vibration occurred in a vehicle. CONSTITUTION: A cooking apparatus(100) of an intake manifold formed of synthetic resin for a vehicle is composed of cooling pipes(130) formed on respective runner(110) separated a certain distance from outside, an inlet line(132) flowing in cooling water and installed on one side of the cooling pipes, and an outlet line(134) flowing out the cooling water absorbing the heat of the air of the runners and formed on the other side of the cooling pipes. The inlet line connected to the outlet of a radiator(140) has a pump(142) circulating the cooling water forcibly and connected to respective cooling pipe dividedly. The outlet line is connected to the cooling line of a transmission(143) by being concentrated from the respective cooling pipe, connected to the inlet of the radiator and circulates in the radiator. Thus, the heat absorbed from the sucked air is released, and the outlet line has lower temperature. And the cooling pipes having the inlet line and the outlet line is separated from the runners.
