Through control logic control, can guarantee total consumption and every under the prerequisite of heating module 6 temperature in the difference in temperature scope, intelligent regulation is every the consumption of heating module 6 has been avoided being close to the heat-generating body temperature of 3 air intakes of fan is low excessively, and the temperature that is close to the air-out department heat-generating body is too high because the heat superposes, and the high temperature has been solved heat unbalance in the heat load system and the heat-generating body that is close to air-out department reduces the power consumption because of the high temperature and the condition that the trouble frequently takes place.
The intelligent control technology of the fan 3 and the heating module 6 is adopted, so that the problems of unbalanced heat, unbalanced temperature (concentrated heating points), high-temperature derating of a heating body, insufficient heat dissipation area and the like of a traditional heat load system are solved, the power consumption density with the same heat load is further improved, and the real conditions of various communication devices can be simulated.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
