The average life span of a heat exchanger is roughy 20 to 25 years. Some can and will make it longer some will go after a few days. It is due to the expading and contracting of the metal with the heat involved.

What is fouling factor this factor used in heat exchangers?
Fouling factor is essentially used in determining the efficiency of the heat exchangers. Fouling factor is obtained from service (product) on either side of tubes and material of tubes. It basically represents corrosion of heat exchangers tubes which affects efficiency of heat transfer.
What is microchannel heat exchangers?
A compact heat exchanger with a hydraulic diameter on the order of 1 mm or less. Flow is typically laminar and heat transfer coefficients are proportional to velocity.
Function of heat exchanger?
There are actually many types of plate heat exchangers, and the YOJO brand has introduced brazed plate heat exchangers and gasket plate heat exchangers. Today is the home of brazed heat exchangers.Brazed plate heat exchangers have no headers, tie rods or sealing gaskets, and the plates are brazed at a temperature of 1100 ° C. During the assembly stage, a piece of brazing material (usually copper, and nickel) is placed between the two plates, the package is compressed, and then baked for several hour.BPHE is more compact and lighter, and the brazing material has the functions of both washer and frame. The intersection between the corrugations of the two coupling plates forms a dense network of contact points, which impart pressure tightness and generate vortex flow, thereby improving heat exchange. In this way, even at low nominal input speeds, the turbulence of the fluid is high, and for low flow rates, the fluid flows from laminar to turbulent.
What is monel metal?
A nickel-copper alloy with high strength and excellent corrosion resistance in a range of media including sea water, hydrofluoric acid, sulfuric acid, and alkalies. Used for marine engineering, chemical and hydrocarbon processing equipment, valves, pumps, shafts, fittings, fasteners, and heat exchangers.
How long do mechanical pencils last?
A life time if you have lead.
Heat exchangers are used in refrigerator or not?
Yes, heat exchangers are used.
What are the problems of heat exchangers?
blocked lines and wear of lines are the most important problems of heat exchangers.
Name the types of heat exchangers used as super-heaters?
Water tube heat exchanger swimming pool, Coaxial heat exchanger for laser and stainless steel exchangers are some of the heat exchangers used as super-heaters.

What is heat duty?
heat duty refers to the heat exchangers. heat duty of the heat exchangers is defined as the amount of heat transfered of 1kg of hot fluid to the 1 kg of cold fluid in one hour.
What is the different between plate heat exchangers and tube heat exchangers?
One uses tubes, the other uses hollow, flat conduits.

What is the purpose of heat exchangers?
Heat exchangers are a system which transfers heat from one place to another. This is an efficient way of heating that is used so that no one place over exceeds the maximum temperature.

Do heat exchangers cause a fire hazard in apartment buildings?
Heat exchangers can be used in many things like space heaters, refrigeration and air conditioning. Heat exchangers by themselves are likely not a significant fire hazard. Space heaters can create a threat of fire if not watched and used properly.
