In the industrial machinery ultra-compact printed circuit heat exchanger is quite important". The most commonly good to use and seen species are “Shell and Tube heat exchanger”. Heat exchange of two fluids passes through the Shell side (red) and the Tube side (Blue). This is important in terms of products (Productivity) and Energy Management.
The types of shell and tube heat exchangers
This can be divided into 3 main types:
- Stationary fixed tube plate heat exchanger
- Moreover, U-tube heat exchanger
- Floating head heat exchanger
Stationary fixed tube plate heat exchanger
Stationary fixed tube plate heat exchanger
Specifications
- Ultra-compact printed circuit heat exchanger is a low cost due to relatively simple design
- But not very high temperature difference between shell and tube (should not exceed 30 degrees in the absence of flexible joint or expansion loop shell)
- Disadvantage is that the tube is very difficult to clean as the tube is completely attached to the shell
- In case of very dangerous fluids that cannot be bombarded, a double tube bundle type is good to use.
U-tube heat exchanger
Features (Specification)
- In the tube side, one side is fixed, the U end releases freely when exposed to heat to expand
- So, it can handle the heat difference between Shell and Tube
- Ultra-compact printed circuit heat exchanger is suitable for Works well at high pressures (> 50 barg)
- Furthermore, most triangular tubing, mechanical or hydro-jet cleaning is difficult.
Floating head heat exchanger
Features (Specification)
- In the Tube side, one side is stationary. The floating head or floating head will release freely when exposed to heat to expand very well.
- But there will be disadvantages. Added another leak point in the system
- In addition, it can handle a very good heat dissipation between Shell and Tube
- Similarly, suitable for high pressure applications. Depending on the type of floating head
The lobe ultra-compact printed circuit heat exchanger can be further classified into 3 sub-types:
1. Floating head with backing device
2. Moreover, packed floating head
3. Pull through floating head
It is good to use for transferring heat from one liquid to another
A plate heat exchanger is a heat exchanger good to use to transfer heat from one fluid to another. This heat transfer takes place through the cross-sectional area. Furthermore, plate heat exchanger consists of a set of hollow plate heat exchangers.
It will be a channel for both parts of the liquid to flow through and exchange heat through such ultra-compact printed circuit heat exchanger. The number of plate heat exchangers good to use depends on the heat exchange capacity (kW).
Similarly, the higher the heat exchange capacity. This type of heat exchanger is mainly good to use for liquid-to-liquid heat exchange. But it can also be good to use for heat exchange for liquids and gases.
The machine: highly resistant to rust
A special feature of plate heat exchangers is that several heat transfer plates are arranged in a fixed distance. Then allow each liquid to flow through the gaps between the plates in an alternate manner. The ultra-compact printed circuit heat exchanger is made of thin stainless steel or titanium plates, which are highly resistant to rust.
It can be removed for cleaning thoroughly easy maintenance. The amount of heat transfer can be adjusted. Furthermore, it comes by increasing or decreasing the number of heat transfer plates
It consists of several plate heat exchangers
Generally, they arrange parallel to each other as a set. A set of heat exchangers is mounted between the front frame and the compression frame, with inlet and outlet pipes located on the front frame. Plate and frame set Secure them together with a set of bolts. It is suspended on the upper suspension beam and located on the lower support beam.
A thin sheet of metal with a wavy surface or is the ultra-compact printed circuit heat exchanger on the plate. There is a gasket around the plate to prevent leaks. It controls the direction of the flow of the flow good to use as an intermediary. A barrier between two liquids with different temperatures causes heat exchange. The heat exchanger medium and food are not in direct contact.
Plate heat exchanger has been good to use in the food industry. Plate heat exchangers include food processing by heat to cause the temperature of liquid food to rise or decrease rapidly during the heating period. It sterilizes liquid food and cools the liquid food after it has been sterilized.
How does ultra-compact printed circuit heat exchanger work?
The working principle of this device is a fixed process in which two shell tubes are divided to transfer the heat of one fluid to another. The fluid does not have to go through the mixing process with a heater. It embeds like a condenser and bringing cooling to reduce the liquid temperature like Evaporator
Shell and tube heat exchanger components structure
Tubes
It is the main component of the shell tube body. The material is made of copper, nickel, titanium, aluminum or steel alloys. It is shaped like a tube with bare skin and fins. The pipe is a type of heat transfer liquid flows to another pipe part of the ultra-compact printed circuit heat exchanger.
Tube-sheet
Grooved rectangular and flat circular slabs are connected around the different areas of the pipe and serve as a separator for the engine room where the heat exchangers and boilers are located.
The pipe plate serves as a support for the liquid in the event that the liquid seeps through the pipes and then leaks. The tube plates provide a space to prevent fluid from flowing out of the shell-and-tube heat exchanger system.
Shell and Shell-Side Nozzles
It is a spherical shape with a mesh plate made of alloy material in ultra-compact printed circuit heat exchanger to support the impact of the flowing liquid. Pipeline and part of the inlet-outlet of fluid at the pipe body (Tube-Side Channel and Nozzles).
It is a pipe made of alloy material. It is responsible for controlling the flow of liquid from the inlet pipe and out of the pipe of the heat exchanger.
Flow guide plates in the shell (Baffles)
It is a guiding pipe that directs the liquid heat to circulate in the direction of the shell of the machine. It also helps to prevent the vibration of the fluid flowing through it.
