The corresponding position of multiple second heat exchange fins offers through hole, and the condensation segment of many heat pipes 51 passes through multiple
The through hole of the second heat exchange fin, and together with the second heat exchange fin fixing assembling.
Heat pipe is a kind of very high heat transfer unit (HTU) of heat transfer efficiency (the leading of the far super any known metal of its capacity of heat transmission
Heat energy power), it will be fast for the heat of heater using the quick thermal transport property of heat-conduction principle and phase change medium
It is external that speed is transferred to heating.Adopt the heat-exchanger rig of heat pipe form in the embodiment of the present invention, can will be derived from clothing
Thing contains the heat Quick diffusing in the damp-heat air in cylinder, is imitated with the condensation improving heat-exchanger rig further
Rate.
According to the work characteristics of heat pipe, heat pipe can be divided into evaporator section, adiabatic section and three sections of condensation segment.When
When the evaporator section of heat pipe is heated (from extraneous absorb heat when), the working medium in heat pipe evaporate by heat for
Steam.Steam flows to the condensation segment of heat pipe in the presence of pressure reduction, and becomes condensation in condensation segment releasing latent heat
Liquid, heat passes through the wick of condensation segment and tube wall scatters and disappears, thus completing heat from high temperature to the transmission of low temperature.
Condensed fluid flows back to evaporator section under the capillary force effect of wick.It will be understood by those skilled in the art that the present invention
The alleged evaporator section of heat pipe 51 in embodiment and condensation segment are with respect to the state of the working medium within heat pipe 51
For, that is, heat pipe 51 absorb heat to make its interior working medium be evaporated to one section of steam is evaporator section, gaseous state
Working medium release latent heat to become one section of condensed fluid be condensation segment.
Further, the material of heat pipe 51 body can be copper, copper alloy, aluminum, aluminium alloy, rustless steel
Or other materials, to ensure the heat conduction efficiency of heat-exchanger rig 50.
In some embodiments of the invention, liquid cooling box 41 can be in substantially cuboid, thus limiting in it
