Description
Technical field
The present invention relates to heat dissipation technology, particularly relate to a kind of plume structure.
Background technology
Plume is seethed with excitement by liquid working substance or evaporates and absorbs amount of heat, and produce steam, steam discharges a large amount of latent heats of vaporization in the place's condensation of plume wall, realizes the exchange of heat.Plume is widely used in the field such as LED lamp, cooling electronic component, the heat on LED chip or electronic devices and components surface is constantly absorbed bottom plume, liquid working substance circulating vaporization-condensation process constantly in condenser pipe, the latent heat of vaporization is dispersed in external environment or the heat dissipation equipment that matches via condensation tube wall rapidly, thus effectively control the temperature of LED chip or electronic devices and components, ensure that stability and the reliability of its work.Existing plume inwall is generally provided with capillary structure, utilizes the capillary force of capillary structure to accelerate the back-flow velocity of condensed water, but owing to generally only arranging capillary structure on the sidewall of plume, under efficiency comparison in existing heat pipe structure.
How effectively to solve heat radiation, become and face problem the most in the urgent need to address at present.
Summary of the invention
The present invention provides a kind of plume structure to solve deficiency of the prior art, arrange integral type capillary structure, efficiency is high, back-flow velocity is fast, good heat conduction effect, and Temperature Distribution is homogeneous in the inside of cylinder.
For achieving the above object, the technical solution used in the present invention is:
A kind of plume structure, the capillary structure comprising cylinder, capillary and be arranged in cylinder, the two ends up and down of cylinder are provided with the upper cover suitable with cylinder and base plate, described upper cover, base plate and cylinder are sealed and matched, have a through hole in the middle part of upper cover, capillary lower end is welded on this through hole, the upper end closed of capillary, and making column body form vacuum seal, vacuum-packed column body rushes filling appropriate amount of fluid working medium; Capillary structure comprises the upper capillary structure arranged along upper cover, cylinder and plate inner wall respectively, middle capillary structure and bottom capillary structure, described upper capillary structure, middle capillary structure are connected with bottom capillary structure, form integrated radiating structure, rapidly heat can be distributed, further raising radiating effect, substantially prolongs the service life of product.
As a kind of preferred version of plume structure of the present invention, described bottom capillary structure is sintered copper powder, and thickness is 1-4mm, middle capillary structure sintered copper powder, and thickness is 0.2-0.5mm.
