Abstract

A radiator is part of the cooling system of an engine that emits a mixture of water and antifreeze, emitting heat while inhaling cool air before returning to the engine.
One issue regarding radiators is where they are mounted on various automobiles.
In automobiles and trucks, the radiator's frontal placement subjects it to extensive damage following a front-end collision and thereby to further automobile impairment due to coolant leakage from the compromised radiator. This report strives to present a new system in the form of a shell-tube heat exchanger to replace the radiator and also do its job. It is able to come up with a scheme that utilizes the radiator by solving the issues and enhancing it in terms of capacity as well as security. This paper is a low-error simulation of the Om457-946 diesel engine manufactured by IDEM Tabriz Company and includes a test report and a precise performance curve. The values are 65.3125 for the no-load heat load and 900 rpm and 120.9513 for the full engine load and 2000 rpm. The engine and thermal efficiency changes at various speeds were studied, and it was discovered that substituting the shell-and-tube exchanger with an automobile radiator not only raises the volume and resistance of the car's cooling system but also raises the power of the engine by 2% and its thermal efficiency by 7%.
