“…Due to the advantages of solar energy, such as its universality, environmental friendliness, capacity, accessibility, and cost-effectiveness, it is posited as a viable solution for solving long-term energy crises [61]. A solar collector is a device that utilizes solar energy to heat fluid (usually water or air), and its main function is to convert solar energy into thermal energy for heating, hot water, and other thermal applications.…”

With the reduction in fossil fuels and growing concerns about global warming, energy has become one of the most important issues facing humanity. It is crucial to improve energy utilization efficiency and promote a low-carbon transition. In comparison with traditional heat exchangers, heat pipe heat exchangers indicate high compactness, a flexible arrangement, complete separation of hot and cold fluids, good isothermal operations, etc. As a result, heat pipe heat exchangers have attracted wide attention and application in various fields in recent years. This paper provides an overview of the application of heat pipe heat exchangers, with a focus on the application in waste heat recovery, and analyzes the opportunities and challenges of heat pipe heat exchanger applications based on existing publications.

“…Heat pipes (Figure 10) can be used to recover waste heat from sources at up to 600 • C [120] or, according to some sources [12], even 1000 • C, but the selection of the working fluid inside the heat pipe as well as the material of the pipe must reflect the actual operating conditions [121]. For example, liquid metals must be used when operation under high temperatures is required [122]. The compatibility of the fluid and pipe material must also be ensured [81].…”

“…Heat pipes feature thermal conductivity rates of up to 200,000 W m −1 K −1 (thus making them suitable for the transfer of heat over relatively long distances [123]), great reliability, and a long service life [103]. The main weakness of heat pipes-primarily in cases when the working medium is solid at ambient temperaturesis their "frozen" startup [122]. The application of heat pipes is common not only in thermal management (typically in the IT sector or the automotive or power generation industries) [120], but also in glass production or solar concentrators [48].…”

The efficient utilization of waste heat from industrial processes can provide a significant source of energy savings for production plants, as well as be a driver of sustainable operations and the abatement of emissions. Industrial waste heat usually is contained in liquid or gaseous outlet streams. Although the possible ways to utilize waste heat are discussed in a wide variety of papers, these either provide only a general overview of utilization options and opportunities or focus on a narrow range of industrial processes. The aim of the present paper is to discuss the practical aspects of waste heat utilization in the European Union so that the reader can gain perspective on (i) the thermal classification of waste heat, (ii) liquid and gaseous waste streams and their typical temperatures for industrial use cases, (iii) the technical, economic, physical, and environmental aspects barring full utilization of the available waste heat, (iv) waste heat sources in various industries, and (v) standardized equipment and technologies applicable to industrial waste heat utilization, including their advantages, disadvantages, and weak points.
