What is the difference between a cooler and a condenser
Article source: unknown Publisher: admin

We don't know where the difference between the cooler and the condenser is in the design. Today we will first talk about this aspect. The differences between the design of the cooler and the condenser are mainly three points. The first point is whether there is a phase change, the second point is the difference in heat transfer coefficient, and the third is the series heat exchanger. Let's talk about these three points in sequence.
1. With or without a phase change condenser, the gas phase is condensed and changed into a liquid phase. The cooling water of the cooler is cooled, there is no phase change, only a simple temperature change; other cooling media they use are not the same. The use is also different, the cooler is used to cool the material, no phase change. The condenser is used to cool and condense the gas phase, and has a phase change.
2. Difference in heat transfer coefficient Generally speaking, because the heat transfer film coefficient in the condensation process is much larger than the cooling process without phase change, the total heat transfer coefficient of the condenser is generally much larger than the simple cooling process, and sometimes it is larger. Magnitude. The condenser is generally used to cool the gas into a liquid. The shell of the condenser is generally very hot, and the concept of the cooler is relatively broad. It mainly refers to a type of heat exchange that converts the hot cold medium to room temperature or a lower temperature. device.
3. If there are two series heat exchangers in series, how should the condenser and cooler be different? In general, the condenser with a large inlet and a small outlet is a cooler, and the same diameter is usually a cooler, which can be easily seen from the shape of the instrument. In addition, when two heat exchangers are connected in series, under the condition of the same mass flow rate, because the latent heat is much higher than the sensible heat, and under the same type of heat exchanger, the larger heat exchange area is the condenser, that is The larger one should be the condenser. The condenser is a heat exchange device that absorbs the heat of vaporous materials and condenses them into liquid materials. There are changes in the phase state, and the changes are appropriate and obvious. The cooling medium can absorb heat directly or directly from the condensed medium, but there is no change in phase change.
