As distributed antenna system, inbuilding solution system , RF passive components , RF power divider, RF Directional coupler, RF coaxial attenuator, and also the RF dummy load are very important.

Dummy load have several kinds.

The simulated load equipment mainly has self-cooling, air cooling, water cooling and other heat dissipation modes. The water-cooled load uses liquid with high specific heat capacity instead of air as refrigerant to dissipate heat for heating power components.

Compared with common air-cooled loads, water-cooled loads consume less power and make less noise. Water-cooled loads are suitable for data centers that require high energy consumption and silence. You can test, accept, and maintain key power supplies such as power supplies, UPS, emergency power supplies, and generators in equipment rooms.

Simulated load device and rack type false load usually adopt air-cooled heat dissipation. Compared with air-cooled, water-cooled load has the following main advantages:

Higher energy consumption efficiency: water-cooled load can save 30%-50% power consumption on average compared with air-cooled load.

Better silence quality: at the same heat dissipation level, the noise of water-cooled load can be reduced by 20-35 dB than that of air-cooled load.

Higher heat dissipation efficiency: the heat taken away by the same volume of liquid is nearly 3000 times that of the same volume of air, and the thermal conductivity of liquid is 25 times that of air.
