Abstract

The invention discloses a waveguide switch with a heat dissipating device, and aims to effectively solve the problem of heat dissipation when the waveguide switch transmits high-power radio frequency signals. The heat dissipating device comprises an inner ring, an outer ring and a heat dissipating wire. The heat dissipating device is mounted at the bottom of the waveguide switch, can quickly transmit heat generated by high-power radio frequency signals to an outer casing of a guided stator of the waveguide switch, effectively reduce the temperature difference between a guided rotor and the guided stator, and avoid rotational failures of the waveguide switch, due to expansion of parts caused by over temperature. The waveguide switch provided by the invention has the advantages of simple structure and light weight, unnecessary nonmetallic materials are not used, the heat dissipation potential of the waveguide switch under high-power working conditions is effectively improved, and the overall high-power reliability of the waveguide switch is improved.

Description

technical field [0001] The invention relates to a waveguide switch for microwave communication, in particular to a waveguide switch with a cooling device, which belongs to the field of electromechanical technology. Background technique [0002] Waveguide switch is an important component of signal path control, widely used in the backup path switch of radar and communication transmitter with high power output; it is also used in microwave transmitting equipment and microwave measurement and control engineering of satellite communication system, and is often used to realize microwave The switch between the antenna and the load-removing channel on the power signal is one of the key components of the satellite signal transmission system. The waveguide switch is mainly used for high-power and high-frequency microwave transmission. Generally, there are four external interfaces. The products that need to be backed up are connected to the four interfaces through the transmission lin...
