How Radiator Works in Car Engine

Introduction

The radiator is an essential part of a car’s cooling system. It helps to keep the engine from overheating by dissipating heat from the coolant. Coolant is a fluid that circulates through the engine and absorbs heat from it. The coolant then flows through the radiator, where it is cooled by the air passing through the radiator’s fins.

Construction of a Radiator

A radiator is made up of a series of thin metal tubes that are arranged in a parallel fashion. The tubes are connected to a top and bottom tank. The coolant flows through the tubes, and the air flows through the fins. The fins help to increase the surface area of the radiator, which allows more heat to be dissipated.

How a Radiator Works

The coolant is pumped through the radiator by the water pump. The water pump is driven by the engine’s camshaft or crankshaft. As the coolant flows through the radiator, it absorbs heat from the engine. The coolant then flows through the radiator’s fins, where it is cooled by the air passing through the radiator. The cooled coolant then flows back to the engine, where it absorbs more heat.

Types of Radiators

There are two main types of radiators: crossflow radiators and downflow radiators. Crossflow radiators have the coolant flowing horizontally through the tubes, while downflow radiators have the coolant flowing vertically through the tubes. Crossflow radiators are more efficient than downflow radiators, but they are also more expensive.

Maintaining a Radiator

A radiator should be inspected regularly for leaks and blockages. Leaks can be caused by corrosion or damage to the radiator’s tubes or tanks. Blockages can be caused by dirt, debris, or scale. If a radiator is leaking or blocked, it should be repaired or replaced.
