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.
It's the flat, flanged cover on the front (and sometimes the rear) of a shell & tube heat exchanger.
Dissipates the heat produced by the heat exchanger through convection and creates static and velocity pressure to distribute the hot air throughout the duct system.
The assumption to design heat exchanger is that it must be a shell and tube device. This device must allow the transfer of heat from one fluid to another without mixing the two fluids.

A condenser boiler has a primary and a secondary heat exchanger. Fuel that is used to simply warm up water can be sent to the secondary heat exchanger and reused. This is a substantially more efficient use of energy.
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.
California has very hot summers and reaches very high temperatures. A heat exchanger can function as air conditioner for someone living in california.
Similar function to a car radiator or an air conditioning condenser. The heat from the fluid is pressurized to build up heat. As it passes through the heat exchanger, the heat from the heated fluid is exhanged to the ambient air which passes through the cooling fins.

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"

It is necessary to schedule a heat exchanger replacement when the current heat exchanger is damaged, malfunctioning, or no longer efficient in transferring heat effectively. Regular maintenance and inspections can help determine when a replacement is needed.
The efficiency of a heat exchanger is directly proportional to its surface area. This means that a larger surface area allows for more heat transfer, resulting in a more efficient 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.
It's the flat, flanged cover on the front (and sometimes the rear) of a shell & tube heat exchanger.
the most effective way to do so is to reduce the flow of the heat exchanger
