Both sides above plate, the one side that one side, intermediate plate upper and lower surface and base plate that cover plate is adjacent with intermediate plate are adjacent with intermediate plate
All being machined with conduit, the conduit of intermediate plate upper and lower surface is identical with the channel structure of cover plate and base plate respectively；Intermediate plate upper and lower two
The conduit in face is communicated by through hole；Two cover plates welds with the joint face of intermediate plate, and intermediate plate welds with the joint face of base plate, structure
Becoming closed cavity, at the internal evacuation of closed cavity and fill working medium, working medium is evaporated condensation in cavity and realizes heat and pass
Pass.
Compared with prior art, useful has the technical effect that the present invention
(1) present invention processes conduit at cover plate, base plate and intermediate plate, it is not necessary to wick, simple in construction；(2) present invention
Entity part between conduit can provide the support that intensity is enough, and anti-pressure ability is strong；(3) work will be filled after internal cavity evacuation
Matter, working medium forms vent plug and fluid column interval layout the state in random distribution in conduit, and at evaporation ends, working medium heat absorption produces
Bubble, expands rapidly and boosting, promotes working medium to flow to condensation at low temperature end；At condensation end, bubble cooling meat also ruptures, under pressure
Fall；Owing to evaporation ends and condensation end exist the pressure imbalance existed between pressure reduction and adjacent conduit so that working medium is in evaporation
Oscillation Flows between end and condensation end, thus realize the transmission of heat；Cover plate and intermediate plate and base plate and intermediate plate are constituted
Cavity interconnects up and down, and the heat that base plate evaporation ends can be made to produce is directly transferred to cover plate condensation end, heat-transfer effect by working medium
More preferably；Working medium equally exists Oscillation Flows in upper and lower cavity body, and equivalent heat transfer coefficient is big；During whole, working medium fully relies on
Thermal drivers carries out oneself's concussion；Its runnability is not influenced by gravitation substantially simultaneously, applies the most extensive.
