hi my name is Cosmo perky Olli and I'm
00:00:08.150 00:00:08.160 the data center cooling solution manager
00:00:09.920 00:00:09.930 for Alfa Laval and today we talk about
00:00:12.830 00:00:12.840 flow rates and how they affect the
00:00:15.200 00:00:15.210 performance of a gasket I paid in frame
00:00:17.120 00:00:17.130 heat exchanger so different flow rates
00:00:19.190 00:00:19.200 are challenging for a gasket Paden frame
00:00:22.190 00:00:22.200 heat exchanger because you have the
00:00:24.380 00:00:24.390 inlet of the cold side and inlet of the
00:00:27.229 00:00:27.239 hot side but then they get distributed
00:00:29.269 00:00:29.279 through the fixed number of channels
00:00:31.549 00:00:31.559 inside the heat exchanger and it's the
00:00:33.319 00:00:33.329 same so a thousand GPM one side and 100
00:00:37.040 00:00:37.050 GPM the other side one of the two is
00:00:39.349 00:00:39.359 inefficient most heat exchangers are
00:00:42.700 00:00:42.710 more efficient if the different if the
00:00:45.950 00:00:45.960 two flow rates are similar between the
00:00:49.099 00:00:49.109 hot and the cold side
00:00:53.090 00:00:53.100 okay here we have a very simple diagram
00:00:56.190 00:00:56.200 it's a draw of Gaskell a plane frame
00:00:59.220 00:00:59.230 heat exchanger when you have the front
00:01:00.900 00:01:00.910 plate the pressure plate and all the
00:01:03.750 00:01:03.760 heat transfer plates so here you have
00:01:07.440 00:01:07.450 your cold Inlet and here you have you so
00:01:18.450 00:01:18.460 as you can see you have the same number
00:01:20.790 00:01:20.800 of channels for the two sides that
00:01:23.640 00:01:23.650 implies that if you have significant
00:01:26.070 00:01:26.080 different flow rates there is a
00:01:28.080 00:01:28.090 challenge for a traditional design
00:01:30.710 00:01:30.720 cascade it put in framing heat exchanger
00:01:33.540 00:01:33.550 if you know that you have different flow
00:01:35.340 00:01:35.350 rates and you cannot avoid that talk
00:01:37.650 00:01:37.660 with your preferred vendor and a
00:01:39.300 00:01:39.310 solution can be designed to minimize
00:01:41.400 00:01:41.410 that effect for instance here the follow
00:01:43.889 00:01:43.899 all we have asymmetrical plates that can
00:01:47.310 00:01:47.320 handle very efficiently different flow
00:01:49.740 00:01:49.750 rates
