A heat exchanger is a device that transfers heat between two or more fluids without mixing them, allowing for efficient thermal energy exchange in processes like heating, cooling, or energy recovery. In contrast, a heater is specifically designed to increase the temperature of a single fluid, typically by adding energy to it, such as in electric or gas heaters. While both devices involve heat transfer, their functions and applications differ fundamentally.

Difference between heat rejection and heat absoarb in refrigerator?
Heat is absorbed by the refrigerant liquid inside the fridge, and rejected by the heat exchanger on the back of it.
Which is more in heat transfer between parallel and counter flow heat exchanger?
Counterflow heat exchangers typically transfer more heat to a fluid simply because the hottest part of the exchanger is where the heating medium enters the heater and the heated medium leaves the heater. In a parrallel flow exchanger the hottest part of the heater is where the heating medium enters, and the coolest part where the heated medium enters, and some temperature in between is found where both exit the heater.
Heat exchanger for ammonia absorption refrigeration system?
there are two type of heat exchanger in absorption refrigeration, first is liquid heat exchanger and other is gas heat exchanger.both heat exchanger function is same, to transfer heat (hot medium to cold medium) without violate second newton law of thermodynamics. liquids heat exchanger is between boiler and absorber vessel mean while gas heat exchanger between evaporator and absorber.
What is the difference between double pipe heat exchanger and shell and tube heat exchanger?
double pipe heat exchanger is made if two concentric tubes one carrying cold flow and the other one carrying hot flow. but shell and tube hear exchangers are made of a shell like a vessel filled with many thin tubes to transfer heat between fluids. there are more data available at : http://scopewe.com/double-pipe-heat-exchanger-design-part-1/
What is heat exchanger duty?
The duty of a heat exchanger can be defined in an easy way as "The amount of heat exchanged from a fluid at a higher temperature to the fluid at lower temperature in unit time by a heat exchanger is called its duty"
What is the differences between an oil cooler and a heat exchanger on an airplane?
difference between cooler and heat exchangers
Difference between heat exchanger and condenser?
A heat exchanger is a device used to transfer heat between two fluids at different temperatures. It can be used for both heating and cooling applications. A condenser is a specific type of heat exchanger that is designed to transfer heat from a vapor to a liquid state, typically used in refrigeration and air conditioning systems.
What is the difference between heater and heat recovery?
Heater produsces - heat recovery finds heat and reuses it
Difference between heat rejection and heat absoarb in refrigerator?
Heat is absorbed by the refrigerant liquid inside the fridge, and rejected by the heat exchanger on the back of it.
What are the benefits of using a heat exchanger?
One major benefit of a heat exchanger is that it quickly transfers heat from one medium to another such as an air conditioning unit or a space heater.
What does a heater core do?
A heater core in a vehicle takes some of the heat from the coolant and runs it through a heat exchanger. The blower in the car that blows hot air into your car runs through that heat exchanger which heats the air that enters your car.
Which is more in heat transfer between parallel and counter flow heat exchanger?
Counterflow heat exchangers typically transfer more heat to a fluid simply because the hottest part of the exchanger is where the heating medium enters the heater and the heated medium leaves the heater. In a parrallel flow exchanger the hottest part of the heater is where the heating medium enters, and the coolest part where the heated medium enters, and some temperature in between is found where both exit the heater.

What is difference between condenser and heat exchanger?
A heat exchanger is a device that transfers heat from one fluid to the others. A condenser is simply a heat exchanger. It compresses refrigerants into a hot gas to then condense them into a liquid. Majorly condenser is used to cool the required vapor and heat exchanger is used to heat the required liquid.
How does a heat exchanger in a tankless water heater contribute to its efficiency and performance?
A heat exchanger in a tankless water heater helps to efficiently transfer heat from the energy source to the water, allowing for quick and on-demand heating. This improves the heater's performance by providing a continuous supply of hot water while minimizing energy waste.
What is terminal temperature difference?
Terminal temperature difference (TTD) is the temperature difference between the hot and cold streams at the end of a heat exchanger. It is a critical parameter in the design and operation of heat exchangers, as it directly affects the rate of heat transfer and the overall efficiency of the system. A smaller TTD generally leads to a more efficient heat transfer process.
How a heat exchanger works?
The way a heat exchanger work is that you can exchange for a another heater for a leased value. You may have to pay a little bit more which in some places it is better to purchase then to lease.
