For certain temperatures also high capacity RTs (e.g. Rubitherm RT 5 HC) are available. The RTHC products possess a higher latent heat capacity of 25 - 30% compared to classic RT materials and melt in a narrower temperature range.

RUBITHERM® RT is a pure PCM, this heat storage material utilising the processes of phase change between solid and liquid (melting and congealing) to store and release large quantities of thermal energy at nearly constant temperature.

2020年10月1日 · In this study, the RT 44 HC employed latent heat to absorb the battery heat. Compared with beeswax, the RT 44 HC absorbed more heat, which resulted in a greater battery temperature decrease. Thus, the combination of a PCM and heat pipe as a passive cooling system efficiently reduced the battery temperature and maintained it below 55 °C.

For this application, Rubitherm's RT44HC [26] was used as PCM, held in capsules 20 mm in diameter, whose main thermophysical properties are reported in Table 2. In addition, RT44HC is a...

2025年1月1日 · This study focuses on optimizing the thermal performance of a novel Boron Carbide (B 4 C) enhanced RT44HC phase change material (PCM) nanocomposite by analyzing the effects of different semi-circular partition placements within a closed cavity.

The RT 44 HC has been suggested as an optimal phase change material for battery thermal management, since its melting point is within the battery temperature range and uses latent heat to store...

RUBITHERM® RT ist ein ungebundenes Wärmespeichermaterial und nutzt den Schmelzvorgang fest/flüssig, um bei nahezu konstanter Temperatur große Wärmemengen zu speichern und bei Bedarf wieder abzugeben. So kann man Wärme und sogar Kälte sehr viel effektiver speichern, als mit allgemein verbreiteten Speichermaterialien.

目的是确定冷却系统的效率，并确定在25–55°C的温度范围内的最佳PCM（蜂蜡或Rubitherm RT 44 HC）。 使用热管会使电池温度降低26。 与没有被动冷却系统的情况相比，在60 W热负载下为62°C。

2023年10月3日 · As a result, an RT 44 HC is more efficient than beeswax because its melting temperature is within the acceptable range for the battery working temperature and because it can absorb more heat than beeswax thanks to its latent heat.

Using beeswax as a PCM in HPs reduces the temperature of BTMS by up to 26.62 °C, while the usage of RT44 in HPs reduces the temperature of BTMS by 33.42 °C. The use of fins along with copper...
