It is widely used in mobile communications, digital television, broadcasting, wireless local area networks, radar, navigation and other fields. A power amplifier generates a large amount of heat when working. If the heat is not discharged in time and is retained in the power amplifier, the components inside the power amplifier will be subjected to very high temperatures, affecting the performance of the power amplifier and reducing the service life of the power amplifier. The existing method usually uses circulating water for cooling and heat dissipation. At present, the cooling equipment of the power amplifier using circulating water cooling is generally in the form of a plug-in, the power amplifier is set in a shielding cover, and the water cooling structure is also set in the shielding cover;
