Description

Technical Field

[0001] The utility model relates to the technical field of broadband power amplification equipment, in particular to a broadband power amplifier. Background Art

[0002] Broadband power amplifiers are mainly composed of power dividers, power amplifier modules, power combiners, couplers and various control circuits. The important characteristics of broadband power amplifiers are that the power amplifier modules have high power consumption, the key processing chip has a small area, generates a lot of heat, and is difficult to dissipate. At present, broadband power amplifiers generally have heat dissipation holes on the casing to ensure the heat dissipation of the processing chip.

[0003] Opening heat dissipation holes on the casing will allow moisture and dust in the external environment to enter the broadband power amplifier, corrode the electronic components in the broadband power amplifier, and shorten the service life. At present, there is also a water cooling method to cool the broadband power amplifier. For example, a liquid-cooled broadband power amplifier disclosed in Chinese patent application number CN201921720615.6 has the following specific contents: including a liquid cooling device circulation pump to fill the lower groove with coolant in the water tank. When the coolant passes through the lower groove, it will take away the heat on the lower heat conduction plate, thereby cooling the processing chip. After carrying the heat, the coolant will enter the cooling pipe for heat dissipation and cooling, and finally flow back to the water tank to realize the circulation of water flow. After being heated, part of the coolant will evaporate and produce a small amount of bubbles. The bubbles will reduce the cooling effect in the lower groove. After floating up, the bubbles will enter the upper groove through the breathable and hydrophobic membrane, and then be discharged from the casing from the exhaust pipe, thereby avoiding the negative effect of bubbles on cooling in the lower groove, thereby achieving efficient cooling and cooling. It has the following technical problems:

[0004] In current life, the broadband power amplifier is prone to fall to the ground due to accidental collision. When the ground is relatively hard, the broadband power amplifier and the liquid cooling device are easily damaged. Utility Model Content
