Abstract

The invention discloses a microwave load, comprising: a body, a wedge-shaped plug, an absorbing sheet, a water inlet pipe and a water outlet pipe. The body is a cuboid with a waveguide cavity, and a V-shaped groove is opened on the side wall of the body along the length direction of the cuboid. A plurality of first water holes are opened on the side wall of the body along the width direction of the cuboid; the wedge-shaped plug includes a side plate corresponding to the end face of the body, and a wedge-shaped part connected to the side plate at one end and corresponding to the V-shaped groove , the wedge-shaped portion is provided with a plurality of second water holes; the absorbing sheet includes a first absorbing sheet and a second absorbing sheet respectively connected to the inner surface of the waveguide cavity, and a third absorbing sheet respectively connected to the two side surfaces of the wedge-shaped portion and the fourth absorbing sheet; the water inlet pipe and the water outlet pipe communicate with the two ends of the first water passage hole and the second water passage hole respectively. On the surface of the wedge-shaped part, an absorbing sheet is placed, which doubles the area of ​​absorption, so that the absorbing sheet can quickly transfer the absorbed microwave heat to the cooling water in the second water passage hole.

Description

technical field [0001] The invention relates to the field of microwave technology. More specifically, it relates to a microwave load. Background technique [0002] The microwave load is one of the important components in the microwave circuit. Its main function is to absorb all the microwave power without reflection. The principle is generally to use the medium to absorb the remaining power of the system to form a matching state without reflection at the terminal. In accelerator systems, high-power loads are often required to absorb radio frequency power, and the development of high-power loads has always been one of the research hotspots in the accelerator field. [0003] According to different structures, the load can be divided into surface absorption matching load and volume absorption matching load. Surface absorption loads are often used in low power applications, and body absorption matching loads are often used for high power. Body absorption load can be divided i...
