Using fins increases the surface area of the cover plate and more is the surface area meaning more place for heat dissipation or heat exchange. In simple words it multiplies the cooling effect.

What is fin pitch in heat exchanger?

Fin pitch refers to the spacing between the fins of a finned heat exchanger. It is often confused as a measure of the fin density which is expressed in terms of fins per inch (FPI). Fin pitch is measured from the centerline of one fin to another and can be determined from summing the fin spacing (distance between fins) and the fin thickness. Generally speaking, smaller fin pitches result in more dense fin arrays which can remove more heat. A point of diminishing returns exists in which the heat exchanger is too dense resulting in insufficient flow of the cooling fluid between fins.


Heat energy is transferred from the hot end of a metal wire to the cool end through?

Heat conduction, by means of particle collisions transferring energy.


A device that heats your home by transferring thermal energy from a region of low temperature to a region at a higher temperature is a?

I think you're talking about a heat engine or heat mover..


What force that is being produced by rubbing two things together?

Rubbing two surfaces together creates friction, which expresses itself as heat. It is possible that static electricity will also be created (probable, actually), but there may or may not be a visible result of the buildup and/or neutralization of the charge (and usually there isn't). The force of friction derives from the electromagnetic forces of atoms and their electrons, so it is atomic and molecular forces that give rise to the phenomenon of friction. There are a lot of variables involved when two surfaces come into contact and move past one another. A link to the Wikipedia post on friction is provided. Heat is studied under the heading thermodynamics, and you'll need to fasten your seatbelt when you get ready to surf over there. An additional link is provided.


Do land surfaces of earth heat more rapidly than water surfaces?

Because sunlight penetrates to greater depths in land than in water.Land is dry, but water washes up onto water surfaces making it wet.

What is Fin efficiency?

actual heat flow rate/ideal heat flow rate if the whole fin was the same temperature as the base of the fins This applies to finned surfaces usually in heat exchangers


What materials insulate heat the best?

Air is the best heat insulator, provided you can prevent it from transferring heat by convection. This is normally made into use in double-glazed windows.


Why are cooling pipes of fridge are provided with thin copper fins?

The thin copper fins on the cooling pipes of a fridge help to dissipate heat more efficiently. The larger surface area created by the fins allows for better heat transfer from the refrigerant inside the pipes to the surrounding air, helping to cool down the fridge more effectively.


What is the purpose of the fins on the indoor and outdoor coils?

The fins act to distribute heat from the system or absorb heat into the system from the surrounding air depending on the location and purpose of the coils carrying the coolant. In a heat pump system, the fins function depends on which way the heat is being transferred. For an air conditioner, the indoor fins bring heat to the coolant from the air and expel heat at the outdoor fins into the air


Is conduction or convection faster when transferring heat?

Convection is generally faster than conduction when transferring heat.


What does ac condenser do?

Refrigerant enters the condenser as a high pressure vapor. In the condenser, the heated refrigerant is cooled by transferring its heat to the air which passes through the condenser fins, and it changes state to a liquid during this time.


How are the processes of heating and freezing related?

They both have to do with the transfer of heat. Heating an object is transferring heat into the system. Freezing an object is transferring heat out of the system.

Which type of surfaces are poor radiators and absorber of heat?

Shiny metallic surfaces, polished surfaces, and light-colored surfaces are poor radiators and absorbers of heat. These surfaces reflect more heat energy than they absorb, which results in lower heat gain.


How does heat flow during heat transfer?

Heat flows through a substance when heat is provided to a substance, the molecules that receives it first gets excited and begins to vibrate to and fro thereby hitting another molecule and transferring this vibration to more molecules thereby transferring the heat energy.
