In the new Hexact 5th generation heat exchanger design software, we now offer specific design options for the brazed heat exchangers. In addition to the heat exchanger design software we now offer a design calculator that is fully integrated in the heat exchanger design software.
The heat exchangers could be made from brazed aluminium or stainless steel. The choice of material is determined by the properties of the media and the required performance. The heat exchangers from stainless steel offer a long product life and are therefore the most cost-effective solution. A heat exchanger from aluminium is more cost-effective than one from stainless steel. However, a heat exchanger made from stainless steel is more resistant to thermal shock and corrosion and has a longer product life.
BPHE heat exchangers are extremely versatile as they can be used for the three main types of heat transfer applications:
Heat and mass transfer to a liquid,
Heat and mass transfer to a gas,
Heat and mass transfer to a liquid-gas mixture.
The double parallel flow channels are more versatile as they are used for heat and mass transfer to a gas and a liquid-gas mixture while the single parallel flow channels are used for heat and mass transfer to a liquid and a gas. The double parallel flow channels offer higher heat exchange performance than the single parallel flow channels. The double parallel flow channels are designed to be wider and higher than the single parallel flow channels.
The design of the heat exchangers could be based on either one or more inlet ports or a single inlet port. The two alternative designs are used for the heat and mass transfer to a gas and a liquid-gas mixture while the single inlet ports are used for heat and mass transfer to a liquid and a gas. The inlet ports and the flow channels are arranged in a way that the incoming cold and hot media flow through the channels from left to right or right to left.
The classical BPHE heat exchanger designs are based on either single or double parallel flow channels. Parallel flow channels are arranged so that they have a flow direction which is parallel to each other or not. Double parallel flow channels are arranged with a 90° offset.

If another hacker does this, then they will be able to put any game on the ps3 in a matter of minutes! and that means that Sony will be out of the console market for good. We have seen what happens when sony doesn't support games anymore. Nintendo is turning a profit, now it is time for Sony to do the same, or else they are dead. 827ec27edc
