Abstract
In recent years, the performance of heat exchanger is demanded strictly. Therefore, it’s important to design a high efficiency heat exchanger for energy saving. In this research, changing circuit arrangement is the way which will make temperature distribution uniformity to improve the performanceof heat exchanger.
There are two section in this research. In the first part, all of arrangements have two circuits. Besides, there are five arrangements tested in different mass flow rate. From the results of experiment, the best arrangement, H Type, is better than the worst arrangement 50 percent in effectiveness.
The second section is about the performance of heat exchanger in different circuits. Increaing circuits will let temperature distribution uniformity but the heat resistance of flow which in the heat exchanger will be decreased. It’s not a good operation for heat exchanger. Thus this research will develope the model and proves it by test. In the results, the theory conforms to the experiment. By the consequence, it is able to design a circuit arrangement of heat exchanger which is high efficiency.
The patent of this research is applied.
