In contrast to the predominant herringbone shape of heat plates, a microplate heat
exchanger has an array of relatively small dimples. Its number and shape define the …

The development of plate heat exchangers has facilitated the extended application of air-
source heat pump water heaters. This study proposes a new type of continuous dimple-plate …

This research discusses single-phase fluid flow conditions at low Reynolds number (Re) in
the heat exchanger with a dimple structure of the heat plate. Flow at 70≤ Re≤ 469 was …

Novel dimple brazed-plate heat exchanger (D-BPHE) for air-conditioning heat-pump
applications is introduced in this study. Understanding the effects of the dimple geometric …

This study analyzes several design cases to identify the optimum geometric structure of the
offset fin, determined by two design factors: the number of fins in the flow direction and the …

The forming of helical coils using a rolling process results in geometrical irregularities
(wrinkles and ovality) that are likely to influence the hydrodynamic behaviour of the flow field …

In engineering phase-change phenomena are found in a multitude of applications, ranging
from refrigeration and air conditioning to steam turbines and petroleum refining. This study …

Abstract" How long is the coast of Britain?" was the question stated by Mandelbrot. Using
smaller and smaller rulers the coast length limits to infinity. If this logic is applied to the fractal …

Offset fin 타입 열교환기는 우수한 열전달 성능으로 인해 소형화가 가능하다는 점 때문에
최근활발하게 연구가 진행되고 있다. 하지만 동시에 비교적 큰 압력강하가 발생한다는 특징이 …
