Abstract
Disclosed is a cooling device of a linear power amplifier in a mobile communication system capable of continuously and repeatedly circulating a cooling water heat-exchanged at a low temperature in a base on which the linear power amplifier is mounted, thus to enable the heat transmitted to the whole liner power amplifier from a radio frequency transistor to be cooled by using the cooling water having a substantially higher coefficient of heat transfer than that of air. The cooling device includes a cooling water generating portion for generating a cooling water of a low temperature within an outer body of a base station transceiver subsystem, and a cooling portion for flowing the cooling water of the low temperature generated in the cooling water generating portion to the interior of a base on which the linear power amplifier is mounted, absorbing a surrounding heat to the cooling water of the low temperature, and then discharging the resulting water to the cooling water generating portion.
