in my opinion because the gas is more efficient for trans heat to the material and we use the fins for icrease the heat transfer from the body to the surrounding and the gas will help for econtinuatioin heat transfer from the body because the gas not constant in its temperature and other properties

What is test ring in Heat exchanger?
A test ring in a heat exchanger is a device used during the manufacturing process to verify the integrity and quality of the welds. It typically consists of a metal ring that is welded onto the heat exchanger assembly and then tested for leaks or other defects using pressure or other testing methods. This helps ensure that the heat exchanger will perform effectively and safely once it is installed in its intended application.
What is the application of baffles in heat exchanger?
Baffles in heat exchangers serve to enhance heat transfer efficiency by directing the flow of fluids across the heat exchange surfaces. They create turbulence, which increases the fluid velocity and improves the mixing of the fluids, leading to more effective heat transfer. Additionally, baffles help support the tubes or plates within the exchanger, preventing vibration and ensuring structural integrity. Overall, they optimize thermal performance while minimizing pressure drop across the system.
What tester do you use to test an heat exchanger?
There are different types of heat exchangers. To get an answer the type of exchanger and what type of test you want to do should be stated.
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.
Exchanger is not transfer heat why?
Heat exchanger manufacturers is an ISO 9001 certified company located in Coimbatore, Tamilnadu. The company started its functioning 2011 in, with a strong background in heat exchanger manufacturing. Our well-experienced and dedicated employees consistently thrive to serve our customers with the best heat exchanger solution. visit :: heatexchangersmanufacturers.in
Capacity ratio of a heat exchanger?
It is the ratio of (mdot*Cp)min/(mdot*Cp)max where the heat exchanger contains two fluids for which the mdot*Cp should be calculated for each to determine which one is greater. by doing so one can define the ability of one fluid to carry thermal/heat energy with respect to the other. so this is a way of saying how well can heat be transferred and so how effective is the heat exchanger
Regarding water flow-should pool water go through the filter before it goes to the heat exchanger or should pool water go to the heat exchanger then through the filter before going back into the pool?
it goes ....pump, filter, heater, auto feeder, back to pool...this way the super chlorated water doesn't hurt the heat exchanger...
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"
How many tubes are in the heat exchanger?
The number of tubes in a heat exchanger can vary widely depending on its design, size, and intended application. Typically, shell-and-tube heat exchangers can have anywhere from a few dozen to several hundred tubes. The specific number is determined by factors such as the required heat transfer area, fluid flow rates, and pressure drop considerations. For accurate information, it is essential to refer to the specifications provided by the manufacturer or designer of the heat exchanger.
Why Expansion bellows are required in heat exchanger?
expension belows are used for heat exchanger to avoid thermal stress
When is it necessary to schedule a heat exchanger replacement?
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.
What is the relationship between the efficiency of a heat exchanger and its surface area?
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.
