Problems solved by technology
[0003] Existing heat dissipation performance test schemes mostly use various heaters to transfer heat to the radiator, roughly judge its heat dissipation performance according to the temperature change before and after, or collect and calculate the parameters of some semiconductor devices on some radiators in the power-on state. The resistance value, the test results of these methods have certain limitations. When it comes to the heat loss of the measured object, the more accurate heat dissipation performance data of the radiator cannot be directly collected, so it cannot accurately reflect the heat dissipation of the radiator itself. ability

Description
technical field [0001] The invention relates to the field of performance evaluation of radiators, in particular to a measuring device for the heat dissipation performance of metal radiators. Background technique [0002] With the continuous development of electronic and electrical technology, the degree of circuit integration of semiconductor devices is getting higher and higher, the power of components is higher and the physical size is getting smaller and smaller, and the heat flux density is also increasing. Higher thermal control requirements for electrical components. Also due to the development of the LED lighting industry, its energy efficiency has attracted much attention. Various metal heat sinks have emerged on the market, but there are no corresponding clear heat dissipation performance parameters. Therefore, effectively solving the heat dissipation performance evaluation problem of metal radiators will definitely make the heat dissipation technology of current el...
