Material selection for the manufacturing of the engineering parts is a difficult and complex process. A lot of considerations and calculations are carried out before its selection. In this section, tubular heat exchanger double plates will be manufactured. There are 4 different kinds of metals which was out of which nickel alloy will be used. As stated by Bahmani et al. (2018), it is one of the most useful metallic alloys that can be used for building machinery and engineering parts. The following sections also explain the reason for its selection and also describe the process of using this metal in the manufacturing process.
Section 1: Component Function and Operating Environment
The functioning of the tubular heat exchanger happens with the multiple layers of heat transfer systems present in it. These tubular heat exchangers are used to transmit heat from one object to another which can be either solid or fluid. The exact working specification of a tubular heat exchanger is with the assistance of heat exchanging mechanisms. As opined by Zhao et al. (2017), it is a mechanism used to transfer heat from one object to other using specially designed plates. Summit exchangers and single plates while others have a double bridge to which state and various temperatures and pressures of the substance is used. The main reasons exchanger is reheating substance without actually causing damage to its chemical nature and properties (Hosseinnezhad et al. 2018). For instance, it is very popular in food industries where it is used for heating of food items as well as dehydrating food particles to decrease the moisture. A significant reason why a double plate heat exchanger is more preferred than a single plate is because of its efficiency and speed with which it is allowed to transfer the heat. The functional specification also states that a double plate tubular heat exchanger can retain heat for a longer period as compared to a single plate tubular heat exchanger.
The service conditions for an ideal tubular heat exchanger are explored in the section. Various ways and considerations that must be taken into discussion while designing tubular heat exchanger double plates. These can be temperature approach, plate gaps, joint specifications, pressure drops as well as channel velocity. According to Kangazian and Shamanian (2017), it is observed that several factors come into play while designing a tubular heat exchanger with higher heating accuracy and reheating retention. For instance, exchanger comes with a very low temperature of fruits which can be lesser than 3 F. This kind of temperature approach requires multiple channeling and radiation in the heat plates of the heat exchanger. With increasing gradations in the heat plates, prices of heat exchanger also increase. From the viewpoint of an industrial application, an ideal heat exchanger works in the range of temperature approach of 5 to 10 F which is enough to heat and reheat items in both solids and fluids. In the case of plate gaps, the tubular heat exchanger performs well with lower blood gas because it shows that there is less amount of pressure drop, and the fuel remains close to each other work-related heat transmission. An industrial tubular heat exchanger has applied a gap less than 1.5 mm which insurance a lower velocity as well (Tamna et al. 2016). This velocity also called the channel velocity is essential to consider because in industrial tubular heat exchanger is liable to foul hot malfunction during operation. This happens due to the heat present in the plates that can make the heat exchanger foul the operation. It is also an important state that channel velocity of fewer than 2 feet per flow is sufficient for handling industrial pressure of heat transmission. Thus these considerations are essential while designing and developing a tubular heat exchanger with a double place for any industrial or domestic application.
As observed in the study, nickel alloy is ideal for the manufacturing of the tubular heat exchanger with double plates. The heat exchanger is useful for the transmission of heat from one object to another and is a very effective metal. It will assist in the process of heat transmission during the process. The malleability and conducting ratio of nickel are also very high that helps the nickel alloy to be properly used in the manufacturing of the tubular heat exchanger. Another reason why Nickel alloy is used for the manufacturing of engineering parts like a heat exchanger is that it allows the transmission of heat properly between various surfaces.
