What is the function of the shell in a heat exchanger?

This form of heat exchanger, as the name indicates, is made up of a shell (a huge pressure vessel) with a bundle of tubes inside it. To transfer heat between the two fluids, one fluid flows through the tubes and another fluid flows over the tubes (via the shell). This is called "two-phase" heat exchange because there are two phases of fluid flowing through the tube bundle - a liquid phase and a gas phase.

The shell has an inlet for the first fluid and an outlet for the second fluid. There may be more than one shell connected in series or parallel to each other. Each shell will have its own inlet and outlet valves so that only one can be open at any given time.

The purpose of the shell is twofold: first, it ensures that both fluids remain under pressure; second, it allows heat to be transferred from one fluid to the other by means of the metal walls of the shell which act as heat bridges between the two fluids.

There are three main types of shell design: flow-through, loop, and cross-flow.

In a flow-through shell, both the inlet and outlet fluids flow directly through the core of the exchanger, coming into contact with all the tubes. Thus, all the heat exchanged between the two fluids takes place within the core of the exchanger.

What is a heat exchanger in marine engineering?

A heat exchanger is a piece of equipment that transfers heat from one fluid to another. A heat exchanger can be used to transfer heat between liquids and gases, liquids and liquids, liquids and liquids, and so on. It can be used for various applications such as air conditioning systems, refrigeration systems, heating systems, and desalination plants.

In marine engineering, a heat exchanger is used to transfer heat between two fluids: liquid and gas. This is necessary because water has low thermal conductivity compared to most other fluids. For example, water can only transmit about 1/7th the heat that oil can transmit at the same temperature. Thus, it becomes important to remove some of the heat from the system to keep the water from becoming too hot or cold.

There are several different types of heat exchangers used in marine engineering.

Which of the following is an example of a heat exchanger?

A heat exchanger is most often seen in an internal combustion engine, where a circulating fluid known as engine coolant runs through radiator coils and air flows through the coils, cooling the coolant and heating the incoming air. But any device that transfers heat from one substance to another without any physical contact between them is correct.

2 A plate heat exchanger. A form of heat exchanger is a plate heat exchanger. A type exchanger is made up of thin corrugated plates that are linked in parallel to form a chamber for fluid flow inside it. The plate's opposite sides contain two distinct fluids, between which heat transfer occurs. The third side is open. One example of this type of heat exchanger is the shell-and-tube heat exchanger.

3 An evaporator-condenser. An evaporator-condenser is a device used to change heat energy from one fluid into another. It is composed of four parts: evaporator, condenser, capillary tube bundle, and cooling tower. The basic function of an evaporator-condenser is to use the temperature difference between two liquids to vaporize one liquid and then return it to its original state of liquid after having transferred some heat to the other liquid.

4 Air handler. An air handler is a device used to move air through a building or house by using fans and heating/cooling systems. It can be found in both home and commercial buildings. There are three main types of air handlers: central air conditioners, split-system air conditioners, and unit air conditioners.

5 Blower. A blower is a machine used to produce a flow of air. It can be hand-powered by a fan belt or electric motor powered internal combustion engine.

What is the principle of heat exchangers?

Concepts of heat exchangers simplified Heat exchangers function because heat naturally transfers from higher to lower temperatures. As a result, if a hot fluid and a cold fluid are separated by a heat-conducting surface, heat can be transmitted from one to the other. This is exactly what happens in a heat exchanger.

There are three main types of heat exchangers: air-to-air, water-to-water, and air-to-water. Air-to-air heat exchangers use the transfer of heat between two streams of air. Water-to-water heat exchangers use the transfer of heat between two streams of water. Air-to-water heat exchangers combine the functions of an air-to-air heat exchanger with those of a water-to-water heat exchanger. They are useful when it is not feasible or desirable to use water as the cooling medium.

Heat exchangers come in many shapes and sizes. They are used in refrigerators, freezers, air conditioners, car heaters, and industrial processes. The most common type of heat exchanger is called a radiator. Radiators use the flow of coolant through tubes that carry heat from the engine or motor to the coolant which then spreads the heat throughout the vehicle's body. A component called a header connects several tubes together and distributes the coolant evenly between them.
