“…The effect of inclination is not very noticeable after 15 min of charging, as can be seen from Figure 4a,b. The fluctuations among 0°, 45°, and 90° inclination were attributed to the natural convection on the tablet PC surfaces in the case of the continuous operation [18]. Unlike the continuous operation, no PCM melting was observed at point P3 after 15 min of intermittent charging.…”

“…They employed three cycles of 60 min of battery discharging, 30 min of rest, and 150 min of charging to study the performance of PCM TES units under cyclic operation of the battery packs. Huang et al [18] fabricated a form-stable flexible CPCM for the thermal management of Li-ion batteries that utilizes n-eicosane as PCM. They mimicked a transient working condition by applying 5 min of heating and 10 min of cooling.…”

This paper presents an experimental study of thermal management in a tablet PC under intermittent operation, with phase change materials (PCMs) encapsulated in a very thin aluminized laminate film container. It complements a study of the same system under continuous operation that was published in 2018. Two different types of PCMs were used for the experimental work; PT-37 and n-eicosane. A commercially available tablet PC was used as a test subject to ensure representative dimensions and material properties of every intricate part of the real tablet PC. For intermittent operation, the cycle used corresponds to fifteen minutes of operation (heat generation) followed by fifteen minutes of rest, to imitate a regular usage pattern of a tablet PC. It was observed that thin PCM thermal energy storage (TES) units are capable of providing a reduction in the rate of temperature increase during transient operations for both the electronics and the tablet cover. Reduction in peak temperature of the heat source and external surfaces of the tablet PC was also observed. At the maximum of 8 W operating power, PCMs were able to reduce the back-cover temperature by 20 °C. At all power inputs, heat storage in PCMs resulted in back-cover temperatures lower than 40 °C. Moreover, it was found that the PCM thermal management system tested was not affected by the inclination of the tablet PC. Results obtained from this study confirm that thin PCM encapsulation is indeed a suitable solution to control the temperature in tablet PCs during intermittent operation.

The temperature of high-power lithium-ion batteries has a great influence on their performance, safety, and stability; thus the battery thermal management system (BTMS) is a key component of electric vehicles. In this paper, a novel liquid-cooling BTMS with a thin plate and a slender tube is proposed for prismatic batteries, four different cooling structures of the tube are designed to achieve a high temperature uniformity, and a three-dimensional numerical model is established. The effects of different cooling structures, battery discharge rates, coolant inlet velocities and inner diameters of the slender tube on the thermal performance are investigated. The results indicate that design S3, for which the length of the effective heat transfer tube distributed by each battery increases gradually along the flow direction of the coolant, exhibits the best thermal management performance among the four designed cooling structures, especially in terms of the temperature uniformity. When the inner diameter of the slender tube is 2 mm and the inlet velocity is not less than 0.5 m/s, the maximum temperature difference between the batteries is reduced to 4.23 C at a 2C discharge rate. This study can provide guidance for the structural design of BTMSs for prismatic batteries.

“…Therefore, PCM is an important candidate for applications of energy storage and environmental control materials. For example, PCM-partitioned walls inside buildings can be used to regulate the room temperature [1,2]; PCM-containing temperature-control devices in space equipment can compensate for the large temperature difference between the day and night in space [3]; thermal management by PCMs in electronic devices, batteries, and biochemical storage tanks enables these systems to operate at nominal temperatures [4]; PCMs can be integrated in the design of clothing insulation [5]; the injection of PCM particles into the working fluid in heat flow lines can enhance the heat transfer efficiency [6]; and PCM can also be used in the development of thermal actuators [7]. Kalnaes and Jelle [8] summarized the PCM requirements into high latent heat per unit volume and mass, suitable phase change temperature, capability to operate at low pressure, stable chemical properties, low corrosion rates, nontoxic, recrystallizable, high crystallization rate, low supercooling, small volume change during phase transition, high thermal conductivity, and low cost.…”

In this study, a heat management module containing a microencapsulated phase change material (mPCM) was fabricated from mPCM (core material: paraffin; melting temperature: 37 °C) and aluminum honeycomb structures (8 mm core cell). The aluminum honeycomb functioned both as structural support and as a heat transfer channel. The thermal management performance of the proposed module under constant-temperature boundary conditions was investigated experimentally. The thermal protection period of the module decreased as the Stefan number increased; however, increasing the subcooling factor could effectively enhance the thermal protection performance. When the cold-wall temperature TC was fixed at 17 °C and the initial hot wall temperature was 47–67 °C, the heat dissipation of the module was complete 140 min after the hot-wall heat supply was stopped. The time required to complete the heat dissipation increased to 280 min when TC increased to 27 °C.
