The cooling and/or heating of human body temperature is of critical importance and interest in a myriad of applications, however, the use of thermoelectric cooling has made little impact in this area. Current solutions focus on the use of wearable materials that assist the natural temperature regulation of the human body, or the use of liquid cooli...

... the positively charged carriers in the p-type pellet, the holes, absorb heat from the cold side of the couple and transfer this heat to the hot side of the couple in an anti-clockwise direction. If the polarity of the DC current applied to the thermoelectric couple input terminals is now reversed, as shown in figure 3(b), the thermoelectric couple will now heat the object connected to the cold side of the couple, with the other side of the couple cooling down. In this condition, the thermoelectric couple is referred to as a thermoelectric heater. ...

Abstract. In the article research results are presented, which aim to development of an algorithm for forming the structure of composite fiber insulation with heat-accumulating properties in clothing. The presence of heat-retaining polymer components in the structure of the fibrous composition of materials leads to its general heterogeneity. Combining such materials with traditional fibrous structures is a rather promising area, as it allows for the use of heat-retaining effect not only in thin materials, but also in voluminous thermal insulating materials. As the main core fibrous composition of materials used to study a system of combining with elements of heatretaining components, we have selected composition of polyester fibers of various configurations and sizes. Pattern of connections between the composition of fibers and groups of materials intended for integrating with heat-retaining components, scheme for creating priority fibrous materials with heat-retaining properties, which form heat-protective textile clothing shells we have developed.

It facilitates precise temperature control to within ±0.1 °C It has low manufacturing costs and a wide operating temperature range It can cool below ambient temperature It is location independent, and can operate in any spatial orientation, at high G-levels or in zero gravity More importantly, the cooling elements of a TE module are easily scalable [167][168][169]. For these reasons, TECs have been previously applied for climate control in EVs [170][171][172][173]. ...
Li-ion battery cells are temperature sensitive devices. Their performance and cycle life are compromised under extreme ambient environment. Efficient regulation of cell temperature is, therefore, a pre-requisite for safe and reliable battery operation. In addition, modularity-in-design of battery packs is required to offset high manufacturing costs of electric vehicles (EVs). However, modularity of battery packs is restricted by flexibility of traditionally used battery thermal management systems. For example, scalability of liquid cooled battery packs is limited by plumbing or piping and the auxiliary equipment used in the system. An alternative thermal management system is, therefore, required for modular EV battery packs. In this paper, state-of-the-art developed to control battery temperature near a pre-specified state is qualitatively reviewed with the intent to identify potential candidate for implementation in a modular architecture. Some of the novel techniques that provide high-scalability in addition to appreciable cost and energy-savings over traditional methods are also evaluated while considering the development state and associated technical risks. It is found that only a hybrid system can meet technical requirements imposed by modular design. Based on the current state, phase change materials and thermoelectric devices are more likely to be part of this next generation thermal management system.
