![]() ![]() The simulation analysis of the parallel flow channel after adding the distributor was carried out to explore the influence of the angle and the size of the distributor on the motion state of the fluid medium. In this paper, the distributor angles of 10°, 20°, 30°, 45°, 67.5° and 90° and the distributor radii of 13 mm, 13.5 mm, 14 mm, 15 mm and 16 mm were selected as the research scope. By adding distributors at the inlet of the heat transfer plate, the working performance of the heat exchanger had been improved. The paper analyzed the shortcomings of the current parallel flow channel structure of the plate heat exchanger through the simulation of Fluent software. ![]() The main work of this paper is as follows: (1) Since the parallel flow channels were used in the plate heat exchanger, the working fluid will be unevenly distributed, thereby reducing the heat exchange efficiency of the plate heat exchanger. At the same time, the general law between the structure of the distributor and the fluid uniformity and heat transfer coefficient of plate heat exchanger with small channel had been investigated. The efficiency of heat exchanger was improved by adding a distributor at the entrance of each layer. ![]() The main purpose of this paper is to design a small channel plate heat exchanger that meets the needs of the enterprise. ![]()
