A heat dissipation device for a heating element based on thermosyphon effect and an outdoor unit

Abstract

The utility model belongs to the phase change material refrigeration and heat dissipation technical field especially relates to a heat generating element heat dissipation device and outdoor unit based on thermal siphon effect, and this heat dissipation device includes first evaporation part, condensing portion, gas header, liquid header, wherein, first evaporation part, condensing portion inner chamber is vertically arranged, and gas header, liquid header are distributed in the upper and lower ends of first evaporation part, condensing portion, first evaporation part, condensing portion, gas header and liquid header jointly form closed circulation channel, and utilize thermal siphon effect to make working medium complete evaporation, transmission, condensation and reflux natural circulation, thereby realize the heat dissipation of heat generating element. The application is optimized through structure, makes full use of the self-circulation characteristics of working medium in the evaporation, condensation and reflux process, has the advantages of no external power, high heat dissipation efficiency, compact structure and strong reliability, and is suitable for the application scene such as outdoor unit with limited space and high heat dissipation demand.
