Abstract

The invention discloses a phase-change radiator, which comprises a base plate, a cover plate and a phase-change channel, wherein one end of the phase-change channel is communicated with an inner cavity of the cover plate, the other end of the phase-change channel is communicated with an inner cavity of the base plate, and a working medium is contained in the inner cavity of the base plate. The phase-change radiator is characterized in that the base plate comprises an upper base plate, a lower base plate and supporting partition plates; the upper base plate is connected with the lower base plate, and a base plate inner cavity is formed between the upper base plate and the lower base plate; the supporting partition plates are arranged in an inner cavity of the base plate; multiple supportingpartition plates are arranged in parallel, and the inner cavity of the base plate is divided into multiple channels by the multiple supporting partition plates; each supporting partition plate is provided with a plurality of through holes, the through holes are evenly distributed in the horizontal direction, and every two adjacent channels are communicated through the corresponding through hole;and a gap is formed between the supporting partition plate and the inner wall of the inner cavity of the base plate in the vertical direction, and the gap is communicated with the two adjacent channels.

Description

technical field [0001] The invention belongs to the technical field of radiators, and in particular relates to a phase change radiator. Background technique [0002] Phase change radiators have excellent heat transfer performance and compact size, and are widely used in the cooling of frequency converters in industrial transmissions, as well as heat dissipation or heat exchange components of high-power devices in new energy, smart grid and transportation industries. In the field of heat dissipation technology at home and abroad, many high-efficiency phase-change radiators have been developed by utilizing the characteristics of high evaporation coefficient and uniform temperature of gas condensation and liquid boiling, and high-power electronic components are arranged on the phase-change radiator. If the temperature uniformity of the substrate of the phase change radiator is not good, resulting in a temperature difference between the heating components, it is easy to have tec...
