Heat storage device of travelling wave tube

Abstract

The invention discloses a heat storage device of a travelling wave tube. The heat storage device of the travelling wave tube comprises a phase-change material, a base, a cover plate and a cooling fin, wherein the base is provided with a storage cavity for accommodating the phase-change material, an assembly upper end surface arranged at the top part of the storage cavity, to-be-welded walls of the base, an injection hole, a sealing hole, an assembly lower end surface in contact with a bottom plate of the travelling wave tube, a cooling surface and sealing bolts for sealing the injection hole and the sealing hole, wherein the to-be-welded walls of the base are arranged on the periphery of the inner wall at the top part of the storage cavity; the cooling surface is arranged at the bottom part of the base and is in close fit with a collector of the travelling wave tube; the cover plate comprises a bottom surface of the cover plate and the to-be-welded walls of the cover plate; the bottom surface of the cover plate is in contact with the assembly upper end surface; the to-be-welded walls of the cover plate are welded with the corresponding to-be-welded walls of the base; and the cooling fin and the base are of an integral structure and the cooling fin is in contact with the phase-change material. After heat storage device is adopted, the service lifetime of the traveling wave tube without heat dissipation which is short in continuous working time or the spatial volume is relatively large is prolonged; the effective filling quantity of the phase-change material is increased; and the heat storage capacity of a heat storage part is improved.

Description

technical field [0001] The invention relates to a heat storage device, in particular to a heat storage device on a traveling wave tube. Background technique [0002] Traveling wave tube is an important electronic device in the fields of microwave relay communication, radar, electronic countermeasures and satellite communication. The development of modern communication technology is changing with each passing day, especially the communication equipment in some special fields has a short working time and is limited by the working environment. The ambient temperature exceeds 55°C. It is impossible to provide a cooling system for the traveling wave tube, and the traveling wave tube is required to work without heat dissipation. . As a radio frequency power amplifier, the traveling wave tube has a conversion efficiency of 20% to 50% of the radio frequency power, and 80% to 50% of its energy is converted into heat energy, which needs to be dissipated through the cooling system.

Problems solved by technology

As a radio frequency power amplifier, the traveling wave tube has a conversion efficiency of 20% to 50% of the radio frequency power, and 80% to 50% of its energy is converted into heat energy, which needs to be dissipated through the cooling system. A large number of heat-generating devices such as the collector electrode and the collector electrode will cause accidents such as fusing of the helix of the traveling wave tube and rupture of the collector electrode, which will cause the working of the traveling wave tube to fail.
