Tube condenser is a very common cooling equipment, which also includes a variety of conventional types, such as GLC floating tubular oil condenser, LC tubular condenser, GL tubular condenser. These tubular condensers have the same characteristics: novel structure, small volume, light weight and remarkable heat transfer effect. The tubular condenser can be used in parallel or in series. The following section will give you an analysis of whether the tubular condenser is in series or in parallel.
The heat exchanger in tubular condenser is made of copper tubes with low fins, and advanced manufacturing technologies such as transverse baffle, longitudinal turbulent plate structure and mechanical tube expansion are adopted. Therefore, the above series of advantages can not be compared with ordinary cooling towers. In the actual use process, the same flow rate and initial temperature hydraulic oil should be cooled, two tube-type condensers with the same specifications should be used, and there should be separate waterways to pass the same flow rate and inlet temperature of the cooling water. These two tubular condensers can be used in parallel or in series.
If the oil outlet is cooler, the series connection is better than the parallel connection. Because when the tubular condenser is connected in series, the heat transfer coefficient will increase and the heat transfer capacity will increase with the acceleration of the oil flow rate, and the oil flow will become longer, which corresponds to the increase of the heat transfer area, so the heat transfer capacity will also increase.
However, it should be noted that when the tube-and-tube condensers are running in series, it is necessary to ensure that the heat transfer efficiency of the former condenser is higher than that of the latter. Of course, this method also has some shortcomings, such as faster oil speed, longer process, greater resistance loss of the process, and greater power consumption of the oil pump.
With series connection mode, two tubular condensers can not be overhauled alternately. Once one of the equipments fails and the system is shut down, the reliability of the whole system will be greatly reduced. Therefore, whether in series or in parallel, each has its own advantages, which requires us to measure the actual situation.
