Abstract The use of aluminum radiators in heating systems began with the foreign companies products such as Fondital Group, Global Radiatori, Ferroli, etc. There are now Russian aluminum radiators companies that adhere to European standards, for example ROYAL Thermo, Rifar. The thermal characteristics of radiators are usually specified by the manufacturer. However, they are not always confirmed in practice. This is due to the fact that radiator connecting method is not taken into account. In some technical data sheets, the power reduction factors are given depending on the difference between t

In simulation of the heat transfer between radiator and air flow field, the adoption of the radiator full-size model containing its core body structure with small feature sizes would require huge storage space and not be economical. In view of this question, based on the coupling of multi-scale models simulations, a calculation method of radiator performance is proposed in this paper the reliability of which is verified by an experiment test. Subsequently, the influence on the radiators’ thermal performance of the layout of the parts in front of the radiators is analyzed. Lastly, the layout of

As a key component of the vehicle thermal management system, the design of the frontend cooling module has a significant impact on the overall energy consumption of the vehicle. This article focuses on improving fuel consumption through front-end module matching optimization design. The specific methods are as follows: 1. Adjust the intake to operate the cooling system at the optimal temperature; 2. Reasonably arrange the positions of low-temperature radiators and condensers to achieve the optimal level of air conditioning energy consumption and engine intake temperature affected by radiators;

The quality of the honeycomb radiator structure has a great impact on thermal performance of the LED lamp. In order to make honeycomb radiators structure more uniform and materials fluidity much better; we firstly take use of cold extrusion to form the honeycomb radiator, then it will be machined. In the honeycomb radiator deformation than the larger places where prone to stress concentration, that has a seriously affect on the effect of the radiator forming. Therefore, we optimized the extrusion die, including upper and lower mold prone to stress concentration places create fillet. The result

The automotive industry is growing, encouraging more efficient car cooling systems, especially radiators. Innovations are constantly being made to improve the performance of radiators. Choosing the correct fluid is one of the ways to increase heat transfer. This study aimed to compare the performance of coolant OBC and TiO2/CuO hybrid fluid mixed with coolant OBC to investigate the increase in heat transfer in the car's radiator. The first step is to make TiO2/CuO hybrid fluid with a two-step method, with volume fraction variations of 1.0, 2.0, 3.0, 4.0, and 5.0%, and observe stability for 30

Low-temperature district heating will play an important role in a future free of fossil fuels. This will only be able to be realized through the low-temperature operation of heating systems in existing buildings. Existing radiator systems can operate with low temperatures for most of the year because they are designed for extremely cold days, but errors have to be corrected and the control of the radiator systems needs to be improved. In this paper, we present a strategy to achieve low-temperature operation from the radiator system of a multi-family building in Denmark without a pre-setting fu

Space radiators used in aerospace applications are required to have a minimum weight, for the desired heat transfer rate. To ensure that the radiator has an optimal geometry, it is important that the heat transfer rate be calculated accurately. To obtain the heat transfer rate from the radiator accurately, the radiative interaction between the fin surface and fin base and the variation of thermal conductivity with temperature should be included in the analysis. Taking into account these two phenomena, this study was conducted in order to explore the optimal dimensions of a space radiator. The

As electronic components progressively downsize and their power intensifies, thermal management has emerged as a paramount challenge. This study presents a novel, high-efficiency finned heat exchanger, termed Flat-Plate Oscillating Heat Pipe Finned Radiator (FOHPFR), which employs arrayed flat-plate oscillating heat pipes (OHP) as heat dissipation fins. Three-dimensional (3D)-printed techniques allow the internal microchannels of the FOHPFR to become rougher, providing excellent surface wettability and capillary forces, which in turn significantly improves the device’s ability to dissipate hea

The majority of dwellings in Lithuania are situated in blocks of flats. The dwellings were built after World War II and they are heated by single pipe central heating systems, connected to district heating. The dwellers are not quite satisfied with such a heating system and try to improve it, but do that in a wrong way, by increasing the surface of radiators. Such means lead to violation of thermal regime and comfort conditions for other dwellers. There exists sometimes the necessity of reconstructing premises and together—the heating system.
