00:00:04.740 hi my name is Cosmo perky Olli and I'm 00:00:08.15000:00:08.160 the data center cooling solution manager 00:00:09.92000:00:09.930 for Alfa Laval and today we talk about 00:00:12.83000:00:12.840 flow rates and how they affect the 00:00:15.20000:00:15.210 performance of a gasket I paid in frame 00:00:17.12000:00:17.130 heat exchanger so different flow rates 00:00:19.19000:00:19.200 are challenging for a gasket Paden frame 00:00:22.19000:00:22.200 heat exchanger because you have the 00:00:24.38000:00:24.390 inlet of the cold side and inlet of the 00:00:27.22900:00:27.239 hot side but then they get distributed 00:00:29.26900:00:29.279 through the fixed number of channels 00:00:31.54900:00:31.559 inside the heat exchanger and it's the 00:00:33.31900:00:33.329 same so a thousand GPM one side and 100 00:00:37.04000:00:37.050 GPM the other side one of the two is 00:00:39.34900:00:39.359 inefficient most heat exchangers are 00:00:42.70000:00:42.710 more efficient if the different if the 00:00:45.95000:00:45.960 two flow rates are similar between the 00:00:49.09900:00:49.109 hot and the cold side 00:00:53.09000:00:53.100 okay here we have a very simple diagram 00:00:56.19000:00:56.200 it's a draw of Gaskell a plane frame 00:00:59.22000:00:59.230 heat exchanger when you have the front 00:01:00.90000:01:00.910 plate the pressure plate and all the 00:01:03.75000:01:03.760 heat transfer plates so here you have 00:01:07.44000:01:07.450 your cold Inlet and here you have you so 00:01:18.45000:01:18.460 as you can see you have the same number 00:01:20.79000:01:20.800 of channels for the two sides that 00:01:23.64000:01:23.650 implies that if you have significant 00:01:26.07000:01:26.080 different flow rates there is a 00:01:28.08000:01:28.090 challenge for a traditional design 00:01:30.71000:01:30.720 cascade it put in framing heat exchanger 00:01:33.54000:01:33.550 if you know that you have different flow 00:01:35.34000:01:35.350 rates and you cannot avoid that talk 00:01:37.65000:01:37.660 with your preferred vendor and a 00:01:39.30000:01:39.310 solution can be designed to minimize 00:01:41.40000:01:41.410 that effect for instance here the follow 00:01:43.88900:01:43.899 all we have asymmetrical plates that can 00:01:47.31000:01:47.320 handle very efficiently different flow 00:01:49.74000:01:49.750 rates
