To reduce over heating of an engine by using a modified fin cooling system.

Regulating and controlling the modified cooling systems.

Objective

Basically there are three types of cooling air cooling ,oil cooling and water cooling process.

Modified fin cooling system is the combination of both air and water cooling

Overview

Engine with fins Condenser Coolant (water) Pump Reservoir Copper tube Thermostat Digital display Micro controller Manual switch

Main components of modified fin cooling system

Initially engine with sufficient number of fins are wound with copper tube.

Then from the engine the copper tube is connected to a condenser.

Copper tube from the condenser is connected to a pump. From the pump it is again connected to the engine in a

cyclic process Engine is fitted with a thermostat Thermostat is connected to a digital display Digital display is connected to micro controller Micro controller is connected to the pump Pump is connected to a reservoir The system is provided with a manual switch also

Construction details

Initially coolant is pumped and it passes through the copper tube

The copper tube which is in contact with the surface of the engine absorbs heat

This heat is transferred to the coolant which is flowing inside the tube.

The coolant carrying the heat is condensed by the condenser.

Then the condensed liquid is again pumped to the engine with the help of pump

Working

The engine is connected with a thermostat The thermostat sends the signal to a digital

display The signal is received by the microcontroller If the temperature of the engine reaches the

allotted critical point the micro controller will switch on the pump

This makes the coolant to flow steadily at requierd temperature

Material Copper has many desirable properties for thermally efficient and

durable heat exchangers. First and foremost, copper is an excellent conductor of heat. This means that copper's high thermal conductivity allows heat to pass through it quickly. Other desirable properties of copper in heat exchangers include its corrosion resistance, bio fouling resistance, maximum allowable stress and internal pressure, creep rupture strength, fatigue strength, hardness, thermal expansion, specific heat, antimicrobial properties, tensile strength, yield strength, high melting point, alloy ability, ease of fabrication, and ease of joining.

The combination of these properties enable copper to be specified for heat exchangers in industrial facilities, HVAC systems, vehicular coolers and radiators, and as heat sinks to cool computers, disk drives, televisions, computer monitors, and other electronic equipment.

Non-copper based heat exchangers are also available. Some alternative materials include aluminium, carbon steel, stainless steel, nickel  alloys, and titanium.

This article focuses on beneficial properties and common applications of copper in heat exchangers. New copper heat exchanger technologies for specific applications are also introduced.
