Abstract:
A cooling device of a linear power amplifier in a mobile communication system, comprising:a base on which said linear power amplifier is mounted; 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 said cooling water generating portion to the interior of the base, absorbing a surrounding heat to the cooling water of the low temperature, and then discharging the resulting water to said cooling water generating portion; said cooling portion comprises: a receiving space having horizontal upper and bottom surfaces and vertical both sides in the interior of said base of a right-angled hexahedron having a predetermined thickness and being opened forward and backward; and a cooling unit inserted and drawn into/from said receiving space and for passing the cooling water of the low temperature pumped in said cooling water generation portion; said cooling unit comprising: a pair of first and second cooling plates each having a cooling water moving passage in the interior thereof, a semicircular guide groove in a longitudinal direction on the up and down horizontal positions of the inner sides thereof, a plurality of spring support grooves into which springs having the same number as said plurality of spring support grooves are mounted at predetermined intervals on the inner sides relative to said guide groove, and upper and lower locking protrusions cut to form upper and lower inclined surfaces inclined by a predetermined angle from the outside to the inside on the edges of the outer sides corresponding to the center of said guide groove; two sets of clips each extending to the both sides thereof at the same angle as in the inclined surface of each of said locking protrusions and having a guide hole on the center of the front surface thereof, such that they are inserted into the respective locking protrusions formed on the front and rear ends of said pair of first and second cooling plates in the state where the inner sides of said pair of first and second cooling plates correspond to each other; and upper and lower wrench bolts forming a wrench groove on the front ends thereof and a helix on the back ends thereof, such that they pass through the respective guide groove on the inner sides of said pair and second cooling plates via the front clips and are screw-coupled to the rear clips.
