Comparative study on the performance of flat tube type and wasp-waisted tube type radiators

Abstract

Heat dissipation improvement has always been one of the difficulties in research on assembled radiators. On the basis of the existing flat-tube type assembled radiator, a wasp-waisted tube type assembled radiatoroptimizesthe shape of the radiating tubeto form a new type of assembledradiator. In this paper, the heat dissipation performance of flat tube type and wasp-waisted tube type radiators is compared through simulation and experiment, leading to the conclusion that a wasp-waisted tube type assembled radiator has a higher wind temperature at the airside, lower wind resistance, and better heat transfer capacity because the "wasp-waist" of the radiating tube increases the area of the radiating fin.The study proves that the optimization of the shape of the radiating tubecan improve theheat dissipation performanceofassembled radiators. It providesa possible solution to improving heat dissipation;at the same time, the findings map out a new direction for research on how to improve the heat dissipation performance of assembled radiators.
