During the conventional brazing process of aluminium heat exchanger component (HEX), the temperature measurement of component in brazing furnace is a general requirement in order to control & achieve the required brazing temperature (around 590°C - 610°C) to ensure efficient brazing joints of the aluminium products. The temperature measurement & monitoring during brazing is usually done with the help of temperature sensors alongwith the data logging system, in fact this is currently a widely used method. However, there are many drawbacks in this type of method for which a suitable solution needs to be developed. In this study, a possible development of simulation tool on the basis of data from Al-Si phase diagram & Lever rule, predicting the temperature on the component during brazing using this tool & comparing w.r.t actual measured data are discussed in detail. As a part of further validation, the data from both the data-logger as well as the estimated temperature from the simulation
During thermal performance testing, achieving thermal balance between two fluid mediums of any heat exchanger is critical. Heat balance ratio (HBR) measures the heat transfer imbalance between two sides (source and sink) in a heat exchanger and also helps in ensuring accuracy of test data. There could be many factors which may lead to the imbalance in thermal performance of the sample under testing e.g. sensors accuracy, test operating range, sample orientation, hysteresis in the data acquisition systems etc. Therefore, a testing procedure needs to be established to achieve a better heat balance ratio as low as less than ±5%, which accounts for errors during instrumentation processes, flow losses & manual errors during testing. The current experimental study focuses on a typical coolant aluminium brazed heater core product which is used in automotive applications for passenger cabin heating during the cold climate conditions, windshield demisting and defrosting. In this study, three

As environmental problems such as global warming are emerging, regulations on automobile exhaust gas are strengthened and various exhaust gas reduction technologies are being developed in various countries in order to satisfy exhaust emission regulations. Exhaust gas recirculation (EGR) technology is a very effective way to reduce nitrogen oxides (NOx) at high combustion temperatures by using EGR coolers to lower the combustion temperature. This EGR cooler has been mass-produced in stainless steel, but it is expensive and heavy. Recently, high efficiency and compactness are required for the EGR cooler to meet the new emission regulation. If aluminum material is applied to the EGR cooler, heat transfer efficiency and light weight can be improved due to high heat transfer coefficient of aluminum compared to conventional stainless steel, but durability is insufficient. Therefore, the aluminum EGR cooler has been developed to enhance performance and durability. Test results showed that the

Engine air induction systems hydrocarbon trap (HC trap) designs to limit evaporative fuel emissions, have evolved over time. This paper discusses a range of HC traps that have evolved in engine air induction systems. (AIS) The early zeolite flow through HC trap utilized an exhaust catalyst technology internal stainless steel furnace brazed substrate coated with zeolite media. This HC trap was installed in the AIS clean air tube. This design was heavy, complicated, and expensive but met the urgency of the implementation of the new evaporative emissions regulation. The latest Ford Motor Company HC trap is a simple plastic tray containing activated carbon with breathable non-woven polyester cover. This design has been made common across multiple vehicle lines with planned production annual volume in the millions. The cost of the latest HC trap bypass design is approximately 5% of the original stainless steel zeolite flow through HC trap. There have been a variety of HC trap designs

To assess the ability of a material to create filler metal flow and fill the brazing joint areas during the brazing process, we adapted a method which is called aluminum Flow Factor test. The target is to take benefit of this test in order to reach an optimum level of heat exchanger performance from project development steps. This paper studies similar aluminum clad material compositions coming from different suppliers. After brazing process, significant differences were noticed in the filler metal flow results. This study highlighted the impact of brazing peak temperature to create more or less flow of filler metal. The Flow Factor is promoted by the increase of brazing peak temperature. It also showed that regardless the material gage, at a low peak temperature of 591°C, Flow Factor are quite similar around 0,18. Even if the silicon particle size was not especially studied, compared to others papers, this study didn't show a main impact on Flow Factor results compared to other
As greater emphasis is placed on the development of small fuel-efficient cars, there is a growing need to reduce the size of the inverter used in hybrid vehicles (HVs). However, semiconductor devices and other components are generating larger amounts of heat and the parts used to cool these components are becoming thinner. One issue resulting from these trends is perforations that propagate from coolant paths. This development secured corrosion resistance by controlling sacrificial corrosion protection performance, optimizing the use of Mn and Si materials to reduce susceptibility to grain-boundary corrosion, and taking a microstructural approach to the flow of the brazing filler metal. The developed material was applied to the inverter cooler of a small HV released at the end of 2011
