There are many types of heat exchangers already out there in the market today. Air Heat Exchangers are common parts of several devices and machinery used in many industries today. Most of them are used in our everyday devices whilst some of them play a more specific part in machines that are used in heavy industries and other businesses. These products are needed especially for machines that are used for long hours since they constantly need to be cooled to sustain their efficiency in the business processes.
One type commonly used today is the Counterflow Heat Exchanger, also known as the SHE. These features a coiled tube set-up that can usually be seen installed in pairs of flat surfaces that are coiled in such a way that the two channels will feature a counter-flowing arrangement. Each channel posses a curved path where the mediums usually go during the exchange of heat process.
Advantages of Using SHE
Efficiency in spacing is the main selling point of the spiral heat exchanger. This spacing can also be improved and configured to provide more efficiency during the exchange of heat process. Developers can actually tweak their designs a bit in order to fully maximise their Cross Flow Heat Exchangers Design.
These types can be used to lower capital costs and obtain a smaller footprint in your processes. A big SHE on the other hand can be used by businesses that are conscious of their energy costs and would want this aspect of their business lower. Bigger SHEs provide less pressure and pumping energy therefore using lesser energy whilst operating.
The Spiral Heat Exchanger Set-up
Spiral heat exchangers are constructed in such a way that it would maximise space and efficiency when it is used. The spiral channels used by the SHE are usually separated by the use of spacer studs. Once this has been done, the heat exchanger is enclosed once the main spiral tubes have been placed.
The coverings are welded and are then enclosed by bolting a gasket flat or a cone cover on the SHEs body. This efficiently separates the two mediums involved during the exchange of heat process. This set-up also avoids leakages. Since the liquids that the SHE typically processes are combined with some solids, the tendency for these is to usually cause a stink in the machine. But the lower pressure in which a spiral heat exchanger works with enables it to hold up against fouling up more efficiently than other types of heat exchangers.
The set-up of the SHE also helps it in battling foul substances being stuck during its processes. Foul surfaces inside the device increases the fluid velocity of the SHE thus producing fluid friction that ultimately cleans up the fouled parts of the device. This particular feature can be dubbed as the SHEs self-cleaning feature.
Additional information about SHEs
There are three main types of current produced by a SHE. These are countercurrent flows, cross flows and the distributed vapor flow.
Because of the SHE's set-up and ability to create different kinds of flows in its processes, they are extensively used by companies involved in the business of digester heating, heat recovery, recuperation, effluent cooling and even pasteurisation. It can also be used for waste and sludge treatment. In this case, the spiral heat exchangers would be typically smaller.
