Abstract
The invention provides heat source simulation devices for measuring heat flow density of a spray cooling experiment system, which is mainly applied to a spray cooling or jet cooling test bench and belongs to the field of heat dissipation measurement. For the problem that the heat flow density of heat dissipation in a spray cooling experiment or a jet cooling experiment is not well calculated, theinvention designs a set of relatively reliable heat source simulation devices by changing an input voltage to adjust the simulated heat source power and collecting temperatures of different sections with one-dimensional heat transfer on the heat conducting column to calculate the heat flow density. The device mainly comprises two parts of a ceramic heating part and a heat conducting column measuring heat flow density part, wherein the ceramic heating part is mainly composed of a silicon electronic voltage regulator, an electric parameter measuring instrument, a ceramic heating ring, an insulating cotton, a sheet heat sink and the like; and the heat conducting column measuring heat flow density part is mainly composed of a heat conducting brass column, a thermocouple, an insulating cotton and the like. The device provided by the invention has the advantages such as wide simulation range, stable measurement, simple and safe operation.
Description
technical field [0001] The invention belongs to the field of spray cooling experiments or jet cooling experiments, and more specifically relates to a simulated heat source device which can measure and calculate the heat flux density and is applied to the heat dissipation and cooling experiment platform. Background technique [0002] With the rapid development of science and technology, the power density of electronic components such as electronic high-performance chips, large-scale radars, and high-end servers is increasing year by year. The ensuing heat accumulation and temperature increase have a great negative impact on the service life and performance stability of the equipment. Therefore, efficient heat dissipation in a limited space has become a bottleneck in the development of high-performance, highly integrated electronic devices. The heat generated by high-power electronic equipment is mainly transferred from the inside of the package to the outside of the package t...
