4 Pilan Hydraulic Coolers and Heat Exchangers General Design Considerations A heat exchanger is a device built for effi cient heat transfer from one fl uid to another, both fl uids are separated by a solid wall so that they never mix and are directly contacted thus avoiding contamination. They are widely used in industrial, marine, mining, automotive, chemical and process, Hot water Generation, solar energy, Heating, Ventilation and Air Conditioning Systems. The exchange of heat (energy) from one unit to another is of essence in our today s industry. In fact, no industrial processes to manufacture goods, heating and cooling homes and public places, energy generation and other daily activities could take place without this exchange of heat. There are several sort of Heat Exchanger Desings, the shell and tube heat exchanger is usually the best for higher applications and consists of a series of fi nned tubes, through which one of the fl uids runs. The second fl uid runs over the fi nned tubes to be heated or cooled. Temperature and resistance is set by the choice of materials of its components. The main advantage stems on the easy maintenance thanks to the removable tube stack although surface exchange id smaller than others thus requiring extra length. Another type of heat exchanger is the plate heat exchanger. One is composed of multiple, thin, slightly-separated plates that have very large surface areas and fl uid fl ow passages for heat transfer. This stacked-plate arrangement can be more effective, in a given space, than the shell and tube heat exchanger. Advances in gasket and brazing technology have made the plate type heat exchanger increasingly practical. In HVAC applications, large heat exchangers of this type are called plate-and-frame; when used in open loops, these heat exchangers are normally of the gasketed type to allow periodic disassembly, cleaning, and inspection. There are many types of permanently-bonded plate heat exchangers such as dip-brazed and vacuum-brazed plate varieties, and they are often specified for closed-loop applications such as refrigeration. Plate heat exchangers also differ in the types of plates that are used, and the configurations of those plates. Some plates may be stamped with chevron or other patterns, where others may have machined fins and/or grooves. Other type of Heat Exchangers can be encountered in the market although are not part of the PILAN range, such as Fan coils, Evaporators, Radiators and other devices suited to specific areas of application.

When a physical body, e.g. an object or fl uid, is at a different temperature than its surroundings or another body, transfer of thermal energy, also known as heat transfer, occurs in such a way that the body and the surroundings reach thermal equilibrium. Heat transfer always occurs from a hot body to a cold one. Energy occurs mainly through conduction, convection or radiation. Heat transfer can never be stopped; it can only be slowed down. Heat - a transfer of thermal energy, (i.e., of energy and entropy) from hotter material to cooler material. Heat transfer may change the internal energy of materials. Internal Energy the internal vibrational energy that the molecules or electrons composing all materials contain. Conduction transfer of heat by electron diffusion or phonon vibrations. Convection transfer of heat by conduction in a moving medium, such as a fl uid. Radiation transfer of heat by electromagnetic radiation or, equivalently, by photons. Approach Temperature - is defi ned as the hot fl uid outlet temperature minus the cold fl uid inlet temperature 4

5 Pilan Hydraulic Coolers and Heat Exchangers General Design Considerations Theory and Application of Shell & Tube Heat Exchangers Two fluids, of different starting temperatures, fl ow through the heat exchanger. One fl ows through the tubes (the tube side) and the other s outside the tubes but inside the shell (the shell side). Heat is transferred from one fl uid to the other through the tube walls, either from tube side to shell side or vice versa. The fl uids can be either liquids or gases on either the shell or the tube side. In order to transfer heat efficiently, a large heat transfer area should be used, so there are many tubes. In this way, waste heat can be put to use. This is a great way to conserve energy. Heat exchangers with only one phase (liquid or gas) on each side can be called one-phase or single-phase heat exchangers. Twophase heat exchangers can be used to heat a liquid to boil it into a gas (vapor), sometimes called boilers, or cool a vapour to condense it into a liquid (called condensers), with the phase change usually occurring on the shell side. Boilers in steam engines are typically large, usually cylindrically-shaped shell-and-tube heat exchangers. In large power plants with steam-driven turbines, shell-and-tube condensers are used to condense the exhaust steam exiting the turbine into condensate water which can be recycled back to be turned into steam, possibly into a shell-and-tube type boiler. There can be many variations on the shell and tube design. Typically, the ends of each tube are connected to plenums (sometimes called water boxes or ports) through holes in tubesheets. The tubes may be straight or bent in the shape of a U, called U-tubes. The following sketch shows a typical U-Tube Heat Exchanger with all its components identifi ed: Most shell-and-tube heat exchangers are either 1, 2, or 4 pass designs on the tube side. This refers to the number of times the fl uid in the tubes passes through the fl uid in the shell. In a single pass heat exchanger, the fl uid goes in one end of each tube and out the other. 5

6 Pilan Hydraulic Coolers and Heat Exchangers General Design Considerations Flow arrangement The arrangement is of great importance for Heat Exchangers performance. Flow arrangement indicates the sense on which s are desinged to fl ow. Heat exchangers may be classifi ed according to their fl ow arrangement as follows: Parallel- heat exchangers, the two fl uids enter the exchanger at the same end, and travel in parallel to one another to the other side. (B in the below sketch). Counter- heat exchangers, the two fl uids enter the exchanger from opposite ends. The counter current design is most effi cient, in that it can transfer the most heat. In a cross-fl ow heat exchanger, the fl uids travel roughly perpendicular to one another through the exchanger. (A in the below sketch). Pilan - is a trademark of Comeval Valve Systems Data subject to change without prior notice For efficiency, heat exchangers are designed to maximize the surface area of the wall between the two fl uids, while minimizing resistance to fluid through the exchanger. The exchanger s performance can also be affected by the addition of fi ns or corrugations in one or both directions, which increase surface area and may channel fl uid fl ow or induce turbulence. Optimized devices are known as compact heat exchangers. Shell and tube heat exchanger, single pass (parallel fl ow) Shell and tube heat exchanger, two pass tube side (counter fl ow) 6

7 Pilan Hydraulic Coolers and Heat Exchangers General Design Considerations Concurrent exchange and countercurrent exchange The diagram presents a generic representation of a countercurrent exchange system, with two parallel tubes containing fl uid separated by a permeable barrier. The property to be exchanged, whose magnitude is represented by the shading, transfers across the barrier in the direction from greater to lesser according to the second law of thermodynamics. With the two fl ows moving in opposite directions, the countercurrent exchange system maintain a constant gradient between the two fl ows over their entire length. With a sufficiently long length and a suffi ciently low fl ow rate this can result in almost all of the property being transferred. By contrast, in the concurrent (or co-current, parallel) exchange system the two fl uid fl ows are in the same direction. As the diagram shows, a concurrent exchange system has a variable gradient over the length of the exchanger and is only capable of moving half of the property from one fl ow to the other, no matter how long the exchanger is. It can t achieve more than 50%, because at that point, equilibrium is reached, and the gradient declines to zero. 7

8 Pilan Hydraulic Coolers and Heat Exchangers Single Phase Shell & Tube Heat Exchangers Series A to F The PILAN range of Single Phase Heat Exchangers for liquids consist of a standardised manufacture programme of 6 series and 33 models for thermal transfer application with heat load capabilities well up to 500 KW. Each Unit provides a specifi c performance depending on the process parameters which, conveniently, entered into our selection programme will identify a range of 2 to 3 models that can accommodate to the required service. These Units are manufactured against our inventory of more than 1000 models for immediate delivery being a cheap option thanks to the scale production methods. The main range covers for Hydraulic Coolers (hydraulic oil as process fl uid), Solar Heat Exchangers (to provide hot water from the sun energy obtained through solar panels), Swimming Pool Exchangers (to heat water pools or, otherwise, keep pools cool), coolers for underground duties and other applications within the liquid / liquid fluid phase parameter. All exchangers are based on the designs shown on these data sheets with just some likely variations depending on the duty sector. Main design advantages: 1 Floating Tube Stack; inserted into the accurately machined shell, no recess between the shell and the outside baffl es of the tube stack to avoid thermal loss and fully replaceable for easy maintenance. 2 Brazed or mechanically expanded plate sheet; ensuring tightness of tube circuit to avoid fl uid contamination. Can be brazed to Tin or silver process. Pilan - is a trademark of Comeval Valve Systems Data subject to change without prior notice 3 Three Passes Circuit arrangement; with water inlet and outlet ports in opposite sides. The multiple tube stack baffl e arrangement drives the process fluid across the outside path from inlet to outlet ports ensuring maximal thermal exchange with the cooling medium. Smaller physical units can accomplish the requested heat power thus being lighter and more economical. 4 Bolted Covers; to ease permanent access to the tube stack for maintenance operations. Made in Hot pressed brass or Bronze as standard to avoid pipe work connection clogging. 5 Finned Tubes; precision rolled, cut to each series length, with bevelled tube ends. Standard 6.5 mm O.D and 0.3 mm wall thickness what increases the thermal exchange properties. 6 Integral anchoring; what provides robustness to the exchanger and eases anchoring to the equipment if wished. 7 Draining Plug; For fl uid emptying during maintenance operations. It is made in brass material to avoid jamming. 8
