TCCbuilder: an open-source tool for the analysis of thermal switches, thermal diodes, thermal regulators, and thermal control circuits

admin — Mon, 11 Nov 2024 07:21:40 +0000

Researchers of the LAHDE laboratory of the Faculty of Mechanical Engineering, University of Ljubljana, have developed an open-source tool for 1D modeling of thermal control circuits, TCCbuilder. It is the first tool of its kind that enables quick and easy modeling of thermal control circuits thanks to its graphical user interface and thr associated library of materials used to create thermal control elements.

In addition to the library of materials, there is also a library of already designed thermal control elements from the literature. Researchers from various fields are invited to complement both libraries as well as to add functionality to the tool. Thus, TCCbuilder is not only an indispensable tool for simulations, but also a platform for the exchange of information and networking of researchers in the field of heat transfer and materials.

The tool is presented in the article TCCbuilder: an open-source tool for the analysis of thermal switches, thermal diodes, thermal regulators, and thermal control circuits, which describes the validation and examples of the use of the tool. The article is published in the journal iScience (IF = 4.6), Special Issue: Advanced thermal control: fundamentals and applications.

The article is freely accessible under the following link: https://doi.org/10.1016/j.isci.2024.111263

Summary:

In the area of thermal management, thermal control elements (TCEs) and thermal control circuits (TCCs) are proving to be innovative solutions to the challenges of temperature control and heat dissipation in various applications, ranging from electronic cooling to energy conversion and temperature control in buildings. Their integration promises to improve power density, energy efficiency, system reliability and system life expectancy. With the aim of connecting researchers in the field of thermal management and accelerating the development of TCEs and TCCs, we have developed an open-source TCC simulation tool called TCCbuilder that enables a quick and easy time-dependent 1D numerical analysis of the behavior of TCEs and TCCs. It uses the heat conduction equation to solve temperature profiles in different devices. The TCCbuilder application offers features not previously available with any other TCC modelling tool: a large adjacent library of materials and TCEs as well as a user-friendly graphical user interface (GUI).

The Calorics 2024 conference took place in the historic city of Cambridge (UK), at the Møller Institute in Churchill College. This event brought together leading experts, researchers, and industry professionals to exchange ideas and insights on the latest advancements in caloric materials and heat-pump technologies.

The presentations highlighted the recent development in magnetocaloric, electrocaloric, elastocaloric, and barocaloric materials, as well as their potential integration in (multi)caloric devices such as heat pumps and active regenerators.

The LAHDE’s contribution to the conference was Prof. Andrej Kitanovski’s presentation: »Challenges, opportunities, and future roadmap for energy applications of magnetocaloric materials«.

One of the standout moments of the conference was the demonstration of a refrigerator utilizing the barocaloric effect to efficiently pump heat, presented by Xavier Moya. Its cooling power was impressive enough to chill beers to the perfect temperature, which were then served to attendees after the presentations. We cannot wait for the day when we can have solid-state refrigerators in our own homes.

Attending the Calorics 2024 conference was an exceptional experience, offering invaluable opportunities for learning and collaboration, encompassed by the engaging discussions with fellow attendees. The wide range of presentation topics provided deep insights into the latest caloric materials and technologies.

We are excited to attend and present our research at the upcoming Calorics conference. We can’t wait to see how the field will develop in the future.

Experimental investigation of buckling stability of superelastic Ni-Ti tubes under cyclic compressive loading: Towards defining functionally stable tubes for elastocaloric cooling

lahde — Mon, 21 Nov 2022 20:28:04 +0000

Within the ERC project SUPERCOOL we have investigated buckling stability of elastocaloric tubes and define the buckling phase diagrams, based on which functionally stable tubes to be used in elastocaloric devices can be selected. The results are published in International Journal of Solid and Structures.

The paper is available here in open access: https://www.sciencedirect.com/science/article/pii/S0020768322004012

Abstract:

Elastocaloric cooling technology recently attracted significant attention as an environmental friendly alternative to vapor-compression technology. It is based on the elastocaloric effect, which occurs in superelastic shape memory alloys (SMAs) during stress-induced martensitic transformation. To date, several proof-of-concept devices (mostly based on tensile loading) have been developed, but limited fatigue life was shown to be one of the major issues. Compressive loading improves the fatigue life of such devices significantly, but in return buckling of SMA structure might occur. To overcome this challenge, it is crucial to understand the buckling phenomena of SMA structures, especially for thin-walled tubes that seem to be ideal candidates for application in elastocaloric cooling devices. Here, we experimentally investigated the effects of the diameter-to-thickness ratio (D_out/t) and slenderness (λ) on buckling stability of Ni-Ti tubes that were subjected to cyclic compressive loading. In total, 161 superelastic Ni-Ti tubes with outer diameter (D_out) ranging from 2 mm to 3 mm, Dout/t ranging from 5 to 25 and gauge lengths (Lg) ranging from 6 to 20 mm were tested. The loading procedure consisted of 3 parts: (I) 1 isothermal full-transformation loading cycle, (II) 50 training cycles, and (III) 20 adiabatic cycles to simulate loading conditions in elastocaloric device. We constructed experimental phase diagrams of buckling modes in λ – D_out/t space for constant Dout and in λ – Dout space for constant D_out/t ratio. Marked areas of functionally stable tubes in these phase diagrams give the design guidance for future developments of durable and efficient elastocaloric devices and other applications, e.g. actuators and dampers.

High-performance cooling and heat pumping based on fatigue-resistant elastocaloric effect in compression

lahde — Wed, 19 Oct 2022 20:35:00 +0000

Within the ERC project SUPERCOOL we have developed fatigue-resistant elastocaloric regenerator with record cooling and heat-pumping performance. The results are published in prestigious journal Joule.

The paper is available here in open access: https://www.sciencedirect.com/science/article/pii/S2542435122004123

Abstract:

In recent years, elastocaloric cooling has shown great potential as an alternative to vapor-compression refrigeration. However, there is still no existing elastocaloric device that offers fatigue-resistant operation and yet high cooling/heat-pumping performance. Here, we introduce a new design of an elastocaloric regenerator based on compression-loaded Ni–Ti tubes, referred to as a shell-and-tube-like elastocaloric regenerator. Our regenerator design, which can operate in both cooling and heat-pumping modes, enables durable operation and record performance with a maximum temperature span of 31.3 K in heat-pumping mode or maximum heating/cooling powers of more than 60 W, equivalent to 4,400 W/kg of the elastocaloric material (at temperature span of 10 K). In terms of both maximum performance metrics, these results surpass all previously developed caloric (magnetocaloric, electrocaloric, and elastocaloric) devices and demonstrate the enormous potential of compression-loaded elastocaloric regenerators to be used in elastocaloric devices for a wide range of cooling and heat-pumping applications.
