Patent ID: 8763735

Claim:
A cooling system for an electric vehicle comprising: a box disposed in a lower portion of a vehicle interior and including an air inlet and an air outlet; an electrical component disposed in the box and having a heat dissipating fin; a cooling duct attached to the electrical component and covering the heat dissipating fin; a fan case coupled to an air outlet portion of the cooling duct and having therein a fan for drawing air; and an exhaust air duct disposed in the air outlet of the box and extending into the box, an air discharge port of the fan case facing an air inlet of the exhaust air duct with a predetermined gap therebetween in a direction of air flow, wherein when the air discharge port of the fan case is projected on a plane including the air inlet of the exhaust air duct, the air discharge port of the fan case is opened inside the air inlet of the exhaust air duct and a predetermined gap is formed in a transverse direction to the air flow between the air discharge port of the fan case and the air inlet of the exhaust air duct, and hot air remaining inside the box is discharged to outside the vehicle interior by a negative pressure generated by a gap formed between the fan case and the exhaust air duct.
