Calorimetry methods, there is several measurement methods and means (usually air or water) used to take the heat produced by the tested device. Ideally, the heat is completely absorbed by this means. The calorimeter of open type in which the device under test is placed directly on the circuit and that the refrigerant has to be air. The main disadvantages with the air as refrigerant are difficulties for heat capacitance, temperature increase and the volume flow, we also have that air is very sensitive to environmental changes, humidity, temperature and density, which in its entirety all leads to major errors in measurement each time. Some of its benefits are a simple construction and a response time fast. Improve the accuracy of the open type calorimeter, it performs a balancing test is basically a measure of reference with a certain amount of power that is supplied to the heaters in the test Chamber. With these plays the main measure. Therefore, measures losses can be recalculated by the relationship between the State of temperatures in both tests and the power known as reference. A very common and very important in all types of calorimeter error is the escape of heat through the walls of the calorimeter. The design proposed is based on the technique of direct calorimetry. Presents some design points for its construction methods and the results obtained. As well know the importance having the thermal behavior in an electronic circuit to determine the correct operation, it is of utmost importance to determine quantitatively the flow of heat generated during operation. To do this you need a system that allows us to know this type of data, complying with these limitations and features: A direct and real-time analysis. Designing a system that throw us real results of their thermal behavior during operation, thus will know how it behaves for some time in which it is running. Is suitable for different measurements of heat flow, taking into account their size and geometry of the Board. Reproducible, precise and repeatable measurements, to make reliable thrown results. Visualization of results in a manner that is clear and clean, for ease in understanding and management of results. Materials used are inexpensive and are available in our midst. Make a system that throw us reliable results to evaluate the thermal behavior of an electronic circuit, and thus be able to design, construct and verify, electronic circuits more efficient and better quality standards. Electronic Design Display of data on the PC, the LabView software was used. Design necessarily conformed to economic needs, the way to get a good team at a low cost. The utilities of this software is that it can monitor the temperature (aim), storing data, analysis and transmission of data.
