Closed high-power travelling wave tube transmitter with phase change heat radiator

Abstract

The invention discloses a closed high-power travelling wave tube transmitter with a phase change heat radiator, belonging to the field of a ship borne high-power radar signal environment simulator. The high-power travelling wave tube transmitter comprises a travelling wave tube, a feeder line, a high-voltage line junction box, a high-voltage module, a low-voltage module, a field amplifier, a power supply, an isolator and a phase change heat radiator. When the phase change heat radiator with a low-temperature liquid area, a copper pipe, a high-temperature gas area and heat radiation teeth is used for cooling, cooling liquid in the high-temperature gas area is liquefied under the action of the low-temperature liquid area and flows back under the action of gravity so as to achieve the integral heat balance and ensure that the transmitter does not need to adopt the traditional heat radiation manner. The closed high-power travelling wave tube transmitter with the phase change heat radiatorhas simple structure, low cost and high reliability. The components such as the high-voltage module, the low-voltage module and the like in the transmitter are designed in modular and standard way and distributed reasonably, and have good maintenance performance; and the integral structure can be designed in series.

Description

Technical field [0001] The invention relates to a closed high-power traveling wave tube transmitter with a phase change radiator, belonging to the field of ship-borne high-power radar signal environment simulators, in particular to a ship-borne high-power radar using a closed high-power traveling wave tube transmitter Signal environment simulator field. Background technique [0002] The transmitter is an important part of the high-power radar signal environment simulator, which is generally composed of high-voltage modules, low-voltage modules, traveling wave tubes, and feeders. [0003] Most of the traditional transmitters are in-cabin equipment. Since the interior of the cabin is generally equipped with air-conditioning equipment and the environmental conditions are relatively good, most of the transmitters use an open air-cooled structure as much as possible, and the structural design is relatively simple. For the high-power transmitter in the cabin, due to its large heat dissi...

Problems solved by technology

However, a set of air-cooling or water-cooling system is added, resulting in a large amount of system equipment, high cost, reduced system reliability, and poor adaptability

[0005] Therefore, the existing airtight high-power traveling wave tube transmitters have problems such as large volume, high cost, low reliability and poor adaptability.
