An in-depth analysis of the usage patterns of used condensers reveals that they are a commonly used cooling equipment, characterized by innovative design, compact size, lightweight, and efficient heat exchange. The heat exchangers in used condensers are made of finned copper tubes and utilize transverse baffle plates, longitudinal turbulence plates, and mechanical expansion tube manufacturing processes. For a detailed understanding of used condensers, refer to the following article.
During actual operation, to cool hydraulic oil with the same flow rate and initial temperature, two used condensers of the same specification are required, along with their respective water circuits for cooling water of the same flow rate and inlet temperature. These two units can be used in parallel or in series.
If a warm oil flow is desired at the outlet, series connection is preferable over parallel connection. This is because when the tube bundle cooler is connected in series, the oil flow velocity increases, leading to a higher heat transfer coefficient and thus a greater heat transfer amount. Moreover, the extended flow path of the oil also corresponds to an increased heat transfer area, further enhancing the heat transfer amount.
Be mindful that when secondary condensers are connected in series, the heat exchange efficiency of the first secondary condenser should exceed that of the subsequent one. Of course, this method also has some drawbacks, such as increased oil flow speed, longer process duration, and greater resistance losses in the process, which will also require a higher power consumption from the oil pump.
Used condensers are connected in series, which means they cannot be alternately maintained. If one unit of equipment encounters an issue leading to system shutdown, the overall stability of the system will significantly decrease.
