Abstract

Abstract An intercooler for a supercharger in an internal combustion engine for a vehicle. The intercooler is an air cooled type provided with a pair of tanks which are connected by a core having a plurality of parallel heat exchanger pipes, between which cooling air is passed to cool the air in the pipes. Each heat exchanging pipe is vertically extended. The core has a horizontal elongation in the direction in which the pipes are arranged in juxtaposition which is larger than the vertical elongation in the direction in which each heat exchanger pipe is extended.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 229 words
A vehicle comprising an engine room having a radiator grille at a front end thereof, an engine room hood lock support at a position behind said radiator grille, a bumper located below said radiator grille, and an air dam skirt located below said bumper; a tranversely extending chamber-like space formed between said radiator grille, said hood lock support, said bumper and said air dam skirt; an engine body provided within said engine room; a supercharging system in fluid communication with said engine body, said supercharging system comprising a pair of turbochargers arranged in parallel; and an intercooler provided in said chamber-like space, said intercooler comprising an inlet tank in fluid communication with said supercharger system for receiving compressed air therefrom, an outlet tank in fluid communication with said engine body for introducing cool air into said engine body, and a radiator core arranged between said inlet tank and said outlet tank, said radiator core comprising a plurality of horizontally juxtaposed and vertically extending heat exchanger pipes between which air can pass in order to cool compressed air in said heat exchanger pipes, said radiator core having a length in the horizontal direction which is greater than a height of said radiator core in the vertical direction; wherein air passing over said air dam skirt, below said bumper, is directed onto said vertically extending heat exchanger pipes of said intercooler.
Claim 2
Dependent Claim 229 words
A vehicle comprising an engine room having a radiator grille at a front end thereof, an engine room hood lock support at a position behind said radiator grille, a bumper located below said radiator grille, and an air dam skirt located below said bumper; a tranversely extending chamber-like space formed between said radiator grille, said hood lock support, said bumper and said air dam skirt; an engine body provided within said engine room; a supercharging system in fluid communication with said engine body, said supercharging system comprising a pair of turbochargers arranged in parallel; and an intercooler provided in said chamber-like space, said intercooler comprising an inlet tank in fluid communication with said supercharger system for receiving compressed air therefrom, an outlet tank in fluid communication with said engine body for introducing cool air into said engine body, and a radiator core arranged between said inlet tank and said outlet tank, said radiator core comprising a plurality of horizontally juxtaposed and vertically extending heat exchanger pipes between which air can pass in order to cool compressed air in said heat exchanger pipes, said radiator core having a length in the horizontal direction which is greater than a height of said radiator core in the vertical direction; wherein air passing over said air dam skirt, below said bumper, is directed onto said vertically extending heat exchanger pipes of said intercooler.
Claim 3
Dependent Claim 18 words
