Thermoelectric Cooler

Thermoelectric coolers are widely used for electronics cooling in various application areas, ranging from consumer products to spacecraft design. Exploiting the Peltier effect, they consist of several thermoelectric legs sandwiched between two thermally conductive plates, one cold and one hot. Due the variety of applications, there can be many different thermoelectric cooler configurations. The ...

Rapid Thermal Annealing

In the semiconductor industry, rapid thermal annealing (RTA) is a semiconductor process step used for the activation of dopants and the interfacial reaction of metal contacts. In principle, the operation involves rapid heating of a wafer from ambient to approximately 1000–1500 K. As soon as the wafer reaches this temperature, it is held there for a few seconds and then finally quenched. An ...

Parameterized Window and Glazing Preset Model

During the design of a building, environmental issues have gained considerable influence in the entire project. One of the first concerns is to improve thermal performances. In this process, simulation software are key tools to model thermal losses and performances in the building. The international standard ISO 10077-2:2012 deals with thermal performance of windows, doors and shutters. It ...

Thermal Bridges in Building Construction - 2D Composite Structure

This example studies heat transfer in a composite two-dimensional structure. Four materials with distinct thermal conductivities k compose the structure. The top and bottom boundaries are facing environments respectively at 0°C and 20°C. The temperature distribution and the heat flux through the structure are compared with published data. This example corresponds to the case 2 described in ...

Thermal Bridges in Building Construction - 3D Structure Between Two Floors

This model studies the heat conduction in a building structure separating two floors from the external environment. Four materials with distinct thermal conductivities k compose the structure. The exterior and interior boundaries are facing environments respectively at 0°C and 20°C. The lowest temperatures on internal surfaces and the heat fluxes through each surface is compared with published ...

Equivalent Properties of Periodic Microstructures

Periodic microstructures are frequently found in composite materials, such as carbon fibers and honeycomb structures. They can be represented by a unit cell repeated along three directions of propagation. To reduce computational costs, simulations may replace all of the microscopic details of a composite material with a homogeneous domain with equivalent properties. This app computes the ...

Thermal Bridges In Building Construction - 2D Square Column

This example studies heat transfer in a square column. Cold and hot temperature conditions are applied to the boundaries. Due to the symmetry of the problem, the geometry is simplified to half of the square. The temperature field is compared with the analytic data. This example corresponds to the case 1 described in the European standard EN ISO 10211:2007 for thermal bridges in building ...

Thermal Bridges in Building Construction - 3D Iron Bar Through Insulation Layer

This model studies the heat conduction in a thermal bridge made up of an iron bar and an insulation layer that separates a hot internal side from a cold external side. The heat flux between internal and external side and the maximum temperature on the external wall are compared them with published values. This example corresponds to the case 4 described in the European standard EN ISO 10211 ...

Finned Pipe

Finned pipes are used for coolers, heaters, or heat exchangers to increase heat transfer. They come in different sizes and designs depending on the application and requirements. When the fins are placed outside the pipe, they increase the heat exchange surface of the pipe so that a cooling or heating external fluid can exchange heat more efficiently. When placed inside the pipe, it is the inner ...
