The potential customer can therefore easily find an adequate exchanger that will suit his application. However, a number of pieces in a batch is lower in HVAC sector than in the automotive industry, and aerodynamic tunnel testing would be too costly for each piece as a result. The solution ...

If some passages in the heat exchanger are very wide, i.e. have several parallel channels, the turbulence during cleaning may not be enough to remove fouling deposits effectively. On the other hand, if some passages are very narrow, i.e. few parallel channels, the turbulence may be so...
To model a multi-pass heat exchanger, you can arrange multiple Heat Exchanger (TL-MA) blocks in series or in parallel. For example, to achieve a two-pass configuration on the moist air side and a single-pass configuration on the thermal liquid side, you can connect the moist air sides...
Chapter 10 Heat Exchanger (换热器)传热学 教学课件.ppt,10-4 Types of Heat Exchangers 1. Heat exchangers of double-pipe arrangement (套管式换热器). Either parallel flow (顺流) or counterflow (逆流) may be used with either hot or cold fluid occupying the an
through one part of the exchanger and transfers its heat either to a cool fluid (water or air, for example) in another part or to the air outside of the exchanger. A car radiator is a heat exchanger, transferring the heat in a liquid that has circulated through the engine to the air...
transfer performance for a given heat exchanger. Usually in this case the flow rates, the heat capacities of the two fluids, surface area, and two of the four temperatures are known, and the other two temperatures are to be evaluated. 5. Off-design calculation (校核计算) When the inle...
14.6. In the second part of the chapter, basic considerations for heat exchanger design have been presented followed by defining of fouling factor, and clean and design overall heat transfer coefficients. An illustrative example of double pipe heat exchanger design has been given....
