Abstract

The objective of the present invention is to provide a pipe for generating fluid turbulence and a heat exchanger including the same, which increases the mixing of fluids flowing into the heat exchanger header by increasing the generation of fluid turbulence through the formation of a spiral structure in the inner diameter of a pipe connected to the heat exchanger header that generates fluid turbulence. A pipe for forming turbulence of a fluid according to one embodiment of the present invention for achieving the above objective is characterized by comprising a pipe frame in which a passage for fluid movement is formed, and a turbulence generating part installed in the passage and including a spiral projection.

Description

Pipe for forming turbulence of fluid and heat exchanger including the same The present invention was devised (conceived) as a result of the research on the "Development of a Numerical Model of a Composite Heat Exchanger for Eco-friendly Vehicles through Ideal Flow Analysis Techniques" of the 3rd stage Industry-Academic Cooperation Leading University Development Project (LINC 3.0), which was supported by funding from the Ministry of Education and the National Research Foundation of Korea. The objective of the present invention is to provide a pipe for forming fluid turbulence to increase the mixing rate of the fluid flowing in the heat exchanger header, and a heat exchanger including the same. A heat exchanger is a device that transfers heat between two or more fluids. The primary purpose of a heat exchanger is to efficiently transfer heat from one fluid to another to save energy or maintain a desired temperature. Typically, heat exchangers operate using various heat transfer methods such as convection, conduction, and radiation. The most common methods among them are convection and conduction, where the hot fluid loses heat and the cold fluid gains heat; thus, in this process, the two fluids are not directly mixed, and heat is exchanged while physically separated. Heat exchangers with this type of operation are widely used in industrial fields such as heating, air conditioning, power generation, waste heat recovery, and chemical processes. There are many types of heat exchangers, including shell and tube heat exchangers, plate heat exchangers, and fin-tube heat exchangers. Among them, plate heat exchangers, which exchange heat by stacking several thin, corrugated metal plates, are widely used because they are easy to maintain and can be easily disassembled and cleaned due to their simple structure. Meanwhile, conventional pipes, which serve as passages for introducing or discharging fluid into plate heat exchangers, were mainly configured in a circular shape. The fluid flows through a conventional circular pipe to the heat exchanger header and is then distributed from the header to multiple plates installed in the heat exchanger; however, the structure of the circular pipe does not allow for proper mixing of the fluid, which leads to a problem of reduced heat transfer performance in the heat exchanger.
