Abstract

The invention provides a radiator and communication equipment, and relates to the technical field of heat dissipation. The radiator comprises a substrate and rib plates, the substrate comprises a substrate cavity, and a rib plate comprises a rib plate cavity. The substrate comprises a first plate surface and a second plate surface, the second plate surface is provided with an open groove, and the substrate cavity is filled with a liquid working medium. The rib plate comprises at least one partition plate, the at least one partition plate divides the rib plate cavity into at least two cavities, and the at least two cavities respectively communicate with the substrate cavity; and one end of the rib plate is inserted into the substrate through the open groove, and one end of the partition plate is located in the substrate. According to the radiator, when the liquid working medium in the substrate absorbs heat and becomes a gaseous working medium, the gaseous working medium enters all the cavities of the rib plates. Meanwhile, the rib plates exchange the heat with an external medium, so that an internal gaseous working medium is condensed into the liquid working medium. The liquid working medium flows back to each area position of the substrate along the partition plate, so that efficient two-item uniform-temperature heat dissipation of the radiator can be realized.

Description

technical field [0001] The present application relates to the technical field of heat dissipation, in particular to a heat sink and communication equipment. Background technique [0002] Mobile communication base station video remote unit (radio remote unit, RRU), massive multiple-input multiple-output antenna (massive multiple-input multiple-output antenna, Massive MIMO Antenna), etc., with the continuous increase in transmission power and integration, they are facing Facing the challenge of heat dissipation with high power and high heat density. In order to meet the reliable operation of various outdoor harsh environments such as ice, snow, heat, wind, sand and salt fog, such equipment usually uses fanless natural heat dissipation to avoid overheating and downtime of the base station due to fan failure. [0003] At present, the heat dissipation scheme of the base station is usually that one side or both sides of the base station box is carried with a radiator. The radiato...
