Heat Dissipation Design of High Power LED Headlamp

1. Overview: 2. Background: High-brightness white light-emitting diodes (LEDs) are very promising in many new illumination applications. LED light sources offer advantages such as long lifespan, fast response speed, environmental friendliness (mercury-free), and a color temperature (5500K-6000K) closer to natural light than xenon sources (4000K). The increasing use of LEDs in automotive lighting (interior lights,

Design of gravity assisted heat exchanger and its application on enhanced waste heat recuperation utilizing organic Rankine and LNG system

1. Overview: 2. Research Background: The research addresses the growing global energy demand, projected to increase by 33% by 2050 [1]. A significant portion of energy is wasted as low-grade waste heat in industries like manufacturing and power generation [2, 4]. Conventional waste heat recovery (WHR) methods using heat exchangers often face challenges such as

Design and Manufacturing of High Performance, Reduced Charge Heat Exchangers

1. Overview: 2. Background: Heating, ventilation, air-conditioning, and refrigeration (HVAC&R) systems consume a significant portion of residential and commercial building energy. Reducing refrigerant charge to mitigate greenhouse gas emissions is a crucial objective. Traditional heat exchangers (HXs) using round tubes and fins have limitations in performance improvement and require further miniaturization to meet reduced refrigerant

A Review of Air-Cooling Battery Thermal Management Systems for Electric and Hybrid Electric Vehicles

1. Overview: 2. Background: The paper begins by highlighting the increasing concentration of greenhouse gases (GHGs) since the 1900s, primarily due to the combustion of fossil fuels in internal combustion engines (ICEs). Transportation is a significant contributor to these emissions. Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs) are presented as promising solutions to reduce

Figure 3. Radio filter produced by means of the RSF/RheoMetalTM process. A unique feature of this product is the weight reduction of 1.6 kg facilitated by wall thicknesses as low as 0.4 mm at 40 mm height (aspect ratio 100). High conductivity low Si alloys were used, and thermal transport properties further increased by up to 20% depending on the alloy composition by means of heat treatments, as depicted in the top right diagram by means of arrows denoting the course of the latter (images provided by Comptech AB, Skillingaryd, Sweden).

High-Pressure Die Casting of Al–Ce–La–Ni–Fe Alloys

Benjamin E. MacDonald1, Stuart Wiesner2, Ryan Holdsworth1, Carl Söderhjelm1 & Diran ApelianORCID:orcid.org/0000-0001-9743-606X1 Abstract The effects on phase equilibria of La and Fe additions to the Al–Ce–Ni-based alloy system are explored under high-pressure die casting conditions. The addition of La to Al–Ce–Ni-based alloy system only reacts with Ce synergistically to promote the formation of the Al11(Ce,La)3 intermetallic phase as predicted by CALculation
