Description
Technical field
The utility model relates to electronic equipments, set more particularly to high power electronics such as server, the network equipment, LED light
The dissipation of the standby heat generated.
Background technique
Heat pipe is a kind of efficient radiator, the phase transition process condensed after the evaporation of hot end in cold end using liquid medium,
Conduct heat quickly.Inside heat pipe is to be pumped into negative pressure state, is filled with liquid appropriate, and this boiling point of liquid is low, is easy to wave
Hair.There is liquid-sucking core in heat pipe, is made of capillary-porous material.Heat pipe one end is evaporation ends, and other end is condensation end, works as heat
When pipe one end is heated, liquid rapid vaporization in capillary, steam flows to other end under the power effect of thermal diffusion, and
Cold end condensation releases heat, and liquid flows back to evaporation ends by capillarity along porous material again, and so circulation is more than, until heat pipe
Both ends temperature is equal, and steam thermal diffusion at this time stops.
The structure of existing heat-pipe radiator is usually that the evaporation ends of heat pipe are mounted on the copper soleplate contacted with pyrotoxin
On, the condensation end of heat pipe interts radiating fin.The quantity of heat pipe is limited by the surface size of pyrotoxin, the heat pipe far from pyrotoxin
Thermal resistance it is big, therefore the integral heat sink ability of radiator is restricted.
Summary of the invention
In order to solve the problems, such as that the heat pipe quantity of existing heat-pipe radiator is limited by the surface size of pyrotoxin, this is practical new
Type replaces bottom plate with phase transformation cavity, proposes a kind of phase-change heat equipment scheme.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of phase-change heat equipment, is made of heat pipe and phase transformation cavity, and phase transformation cavity is according to the close of heat pipe principle production
Cavity is sealed, the evaporation ends of heat pipe are inserted into phase transformation cavity；The table wall that cavity is contacted with pyrotoxin is the evaporation ends of phase transformation cavity, cavity
Interior heat pipe table wall is the condensation end of phase transformation cavity.It is inserted into phase transformation cavity using more heat pipes, increases phase transformation cavity condensation end
Area improves radiating efficiency.The condensation end of heat pipe installs the external heat sinks such as cooling fin, or installation water-cooling section.Water cooling portion
The mounting means of part is to be bonded the condensation end of heat pipe with water-cooled plate, or the condensation end of heat pipe is made to be inserted into water-cooling channel；Heat pipe
Evaporation ends and condensation end between water proof component can also be installed, prevent the electronic equipment that evaporation ends are flowed to after cooling water leakage.
The beneficial effects of the utility model are:
Heat pipe is inserted into phase transformation cavity, using the velocity of sound characteristics of heat transfer of steam, can break through by a kind of phase-change heat equipment
The limitation of pyrotoxin surface size increases the quantity of heat pipe in solid space direction, to expand effective heat dissipation area；Cause
This, which has the characteristics that heat radiation power is adjustable, can well solve the heat dissipation problem of high-power die.
