Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a heat dissipation measurement system, a heat dissipation measurement method, and a heat dissipation measurement control device. Background technique [0002] The main heat dissipation methods of the equipment with built-in heat source to the external environment are radiation heat exchange and natural convection heat exchange. It directly affects the power consumption and user experience of the device, such as a refrigerator with a built-in condenser. [0003] The heat dissipation of the equipment with the built-in heat source is small in magnitude, and the natural convection has a greater impact on the radiation heat dissipation. The existence of natural convection heat dissipation will also cause the temperature of the outer wall surface of the equipment to decrease, which will reduce the measured radiation heat dissipation and change the range. larger. Therefore, in th...

[0003] The heat dissipation of the equipment with the built-in heat source is small in magnitude, and the natural convection has a greater impact on the radiation heat dissipation. The existence of natural convection heat dissipation will also cause the temperature of the outer wall surface of the equipment to decrease, which will reduce the measured radiation heat dissipation and change the range. larger

Therefore, in the process of measuring radiation heat dissipation, if the influence of natural convection heat dissipation is not suppressed, it is impossible to accurately evaluate the proportion of radiation heat dissipation and the radiation heat dissipation, which is not conducive to the improvement of radiation heat dissipation efficiency of products, and is not conducive to guiding the energy saving of the equipment under test.
