Can heat exchanger be used for cooling?
Heat exchangers are commonly used in liquid cooling systems to dissipate heat from a fluid that has passed over a cold plate attached to the heat-producing component. The cool fluid is pumped through the system and back across the cold plate.
What is the common arrangement of heat exchanger?
The most common type of heat exchangers, shell and tube heat exchangers are constructed of a single tube or series of parallel tubes (i.e., tube bundle) enclosed within a sealed, cylindrical pressure vessel (i.e., shell).
What is piping heat exchanger?
The double pipe heat exchanger works via conduction, where the heat from one flow is transferred through the inner pipe wall, which is made of a conductive material such as steel or aluminum. The double pipe heat exchanger is often used in counterflow, where its fluids move in opposite directions (as shown above).
Which pipe is used in heat exchanger?
A double-pipe heat exchanger consists of two metal pipes, one inside the other as shown in Figure 9.3. One fluid flows through the inner tube while the other fluid flows in the annular space between the pipe walls.
What is the difference between cooling tower and heat exchanger?
Cooling Tower is a kind of heat exchanger. The difference lies in the method of energy transfer. The cooling tower may also be considered as a Mass Transfer device because the cooling of water takes place because due to the evaporation of water caused by air.
Is a heat exchanger the same as an air conditioner?
In summary, the entire air conditioner could technically be considered the heat exchanger, but the condenser is the main component responsible for heat transfer.
Which is better parallel flow or counterflow?
Counter flow heat exchangers are inherently more efficient than parallel flow heat exchangers because they create a more uniform temperature difference between the fluids, over the entire length of the fluid path.
How do you know if a heat exchanger is parallel or counterflow?
A counter-flow heat exchanger is one in which the direction of the flow of one of the working fluids is opposite to the direction to the flow of the other fluid. In a parallel flow exchanger, both fluids in the heat exchanger flow in the same direction.
What is pipe layout?
A piping designer does piping layout. This is the process of defining the piece of equipment, the maintenance spaces and the related electrical needs. Then routes the piping to accomplish the process function of the piece of equipment then add the space requirements for operation and you have a piping layout.
Which pipe is more efficient in terms of heat transfer?
A loop heat pipe (LHP) is a passive two-phase transfer device related to the heat pipe. It can carry higher power over longer distances by having co-current liquid and vapor flow, in contrast to the counter-current flow in a heat pipe.
How do cooling pipes work?
The heat boils the fluid and pushes the fluid vapor to the colder region of the heat pipe. The colder region, which is typically coupled to a heat sink, is known as “the Condenser”. The fluid gives up its latent heat and condenses back to a liquid, and is again absorbed in the wick structure.
How does a heat exchanger work with a cooling tower?
A cooling tower is a specialized heat exchanger in which air and water are brought into direct contact with each other in order to reduce the water’s temperature. As this occurs, a small volume of water is evaporated, reducing the temperature of the water being circulated through the tower.
What is the difference between a heat exchanger and a chiller?
The major difference between a heat exchanger and a chiller is in the design. While chiller systems possess refrigeration units that cool their circulating chiller fluid, a heat exchanger lacks a refrigeration unit and achieves temperature regulation by direct fluid heat transfer.
Which type of heat exchanger is used in AC?
MicroChannel heat exchangers
You can find these type of heat exchangers on air cooled chillers, condensing units, residential AC, air dryers, cabinet cooling and rooftop units etc. These type of heat exchangers also work using convection as their main method of heat transfer.
Does a heat exchanger use freon?
HVAC Heat Exchangers Explained The basics working principle how …
Why is parallel flow not efficient?
The key difference between counterflow and parallel flow heat exchanger is that counterflow heat exchanger is highly efficient because it can exchange a maximum amount of heat, whereas parallel flow heat exchanger is less efficient because it cannot exchange a high amount of temperature.
Which heat exchanger design is the most efficient?
Plate exchanger
Plate exchanger is the most efficient due to turbulent flow on both sides. High heat-transfer coefficient and high turbulence due to even flow distribution are important.
Which flow is better in heat exchanger?
Counter flow heat exchangers
Counter flow heat exchangers are the most efficient of the three types. In contrast to the parallel flow heat exchanger, the counter flow heat exchanger can have the hottest cold- fluid temperature greater than the coldest hot-fluid temperatue.
How do I create a piping layout?
Piping Layout Guidelines
Piping for vertical vessels should be located radially around the vessel on the pipe rack side, or should align with adjacent equipment. Leave adequate space for access to platforms, ladders, manways, instruments and drop areas.
What are the criteria of piping layout?
These documents or databases define the following essential information: the system design and operating pressures and temperatures; piping materials; pipe wall thickness or schedules; types of fittings to be used, e.g., butt weld, socket weld, or screwed; and the valve and flange pressure rating and insulation …
What is the most efficient heat exchanger design?
Plate exchanger is the most efficient due to turbulent flow on both sides. High heat-transfer coefficient and high turbulence due to even flow distribution are important.
What makes a heat exchanger more efficient?
High fluid velocity, high turbulence, high surface area and a large temperature differential all contribute to more efficient heat transfer.
How do heat pipe coolers work?

What is the approach of cooling tower?
Figure 7.3 Range and Approach
ii) “Approach” is the difference between the cooling tower outlet cold water temperature and ambient wet bulb temperature. Although, both range and approach should be moni- tored, the ‘Approach’ is a better indicator of cooling tower performance.
