Figure 1. Self Sufficient Home with Combined Heat and Power Combined Heat and Power (CHP) Engineers combined heat and power (CHP) systems, also known as cogeneration, generate electricity and useful thermal energy in a single, integrated system. CHP is not a technology, but an approach to applying technologies. Heat that is normally wasted in conventional power generation is recovered as useful energy, which avoids the losses that would otherwise be incurred from separate generation of heat and power. While the conventional method of producing usable heat and power separately has a typical combined efficiency of 45 percent, CHP systems can operate at levels as high as 80 percent. Some micro-CHP technologies use mechanical engines, such as internal combustion [...]
IC thermal management introduction. This relates to the heat transfer problems encountered by an electrical engineer in semiconductor design.
Figure 1: FLIR image of two houses showing energy loss. Colors towards red on the scale indicate warmer surfaces and more energy loss. The basic principle behind thermal insulation is simple to understand. The harder it is for heat to travel through a material, the better insulator that material will make. In this blog, I’m going to take a look at how that effectiveness is quantified, after a brief review of the three methods of heat transfer. The building and construction industry use a ratio called the R-factor to indicate how well a building material can insulate a space. Also called the thermal insulance or thermal resistance, a higher R-value indicates a more effective insulator. Heat Transfer Methods There are [...]

In this week’s blog we will follow up the previous series of espresso thermal analysis with a thermal analysis that is a little more fitting for this
A thermal analysis experiment of a Bodom tm insulated espresso cup.
Thermal Analysis of Espresso Cup Materials In our blog this week focuses on espresso coffee and the material of the cup in which it is served. The three standard materials that will be tested are paper, Styrofoam and ceramic. Paper cups are designed for cold drinks, so it is likely that they will result in the lowest amount of thermal energy retention in the espresso coffee. Styrofoam cups are designed as a cheaper and single-use alternative to standard ceramic coffee cups. Since they have the ability to handle a large range of temperatures, they will be able to manage the thermal energy in the espresso coffee. Ceramic cups are designed to handle extremely hot temperatures and then be washed [...]
