Description
Technical field
The utility model is related to a kind of plume structure, specifically a kind of composite type heat rod structure.
Background technology
Plume, a kind of special shape of heat pipe（The heated heat pipe in relatively short butt end face）, it is a kind of efficient heat transfer device,
Its axial heat conduction efficiency is more than hundreds times or more of fine copper, the superconductor for heat of being known as.
Operation principle is phase-change heat transfer, and structure is device capillary wick and liquid work in closed vacuum metal pipe
Matter, when heat is passed to from plume bottom inside plume, liquid working substance heat absorption becomes gas evaporation, and quickly turns to tube body condensation end
It moves, liquid is condensed into after condensation end discharges heat, return to fire end along liquid-sucking core, thus constantly recycle, a large amount of heat quilt
It takes away rapidly.
Advantage：1. being functioned under 30 DEG C of low temperature of ＜, generating heat since the heat source position of bottom just plays a protective role；2.
Heat radiation module is made in plume, and heat radiation power is big, and heat conductivility is stablized, and cyclic fluctuation is small.
The shortcomings that prior art：
One, body portions
1》Major part manufacturer produces the upper cover that plume all uses vehicle pin to process, tube body, lower cover three in enormous quantities at present
Then part reuses the formation welding of silver soldering ring and forms seal cavity, vehicle pin is processed with high costs, often covers cost in 10RMB
More than, and easily cause overflow after solder melts when upper cover and pipe welding and enter inboard wall of tube body, pore is blocked, welding portion is not close
The problems such as envelope, average fraction defective is 10% or so.
Two, wicking portions
1, copper powder sintering capillary (filling out powder) needs to use stainless steel or graphite jig as center bar, and jig is easily lost, and takes
With height, low production efficiency；
2, copper mesh capillary can not be fitted closely with inboard wall of tube body, and liquid reflux is caused to have some setbacks, and cannot be satisfied high-power
Demand；
3, it is applied to inboard wall of tube body using resin, adds appropriate copper powder, copper powder is made to be attached in tube wall, though this method
It is easy to operate, it is efficient, but capillary layer thickness is partially thin（About 0.3mm or less）, cannot be satisfied high-power demand.
Three of the above capillary mode respectively has advantage and disadvantage, is all unable to reach high efficiency, high-performance, it is therefore desirable to change to it
Into.
Utility model content
It is mentioned above in the background art to solve the purpose of this utility model is to provide a kind of composite type heat rod structure
Problem.
To achieve the above object, the utility model provides the following technical solutions：
A kind of composite type heat rod structure, including tube body, bottom cover, sintered copper powder capillary layer, copper mesh capillary layer and degasification tubule,
The tube body is arranged in the top of bottom cover, and the inner wall of the tube body is equipped with sintered copper powder capillary layer, sintered copper powder capillary layer it is interior
Copper mesh capillary layer is arranged in side, and degasification tubule is arranged in the top of tube body, and the degasification tubule is connect by welding with tube body.
As further program of the utility model：Annular groove there are two being set on the bottom cover.
As further program of the utility model：The depth of two annular grooves is different, and deeper annular groove is used for
The opening of tube body is inserted into cooperation, and silver soldering ring is placed in the inside of shallower annular groove.
As the utility model further scheme：The inside of the tube body is arranged spring, the end of the spring with
The inner wall of tube body is fixedly connected.
Compared with prior art, the utility model has the beneficial effects that：
1. tube body is high using punching press or the integrally formed production efficiency of rolling mode with upper cover, cost can reduce by 30% or more；
2. tube body is reduced to 0 with upper cover welding the bad of gas leakage,（Solder is easily caused when vehicle pin upper cover is with pipe welding to melt
The problems such as overflow enters inboard wall of tube body after change, blocks pore, welding portion blow-by, average fraction defective is 10% or so）；
3. the capillary structure of design different-thickness can be selected according to the demand of client's power, plume monomer power can be accomplished
200W or more (130W can only generally be accomplished by gluing powder technique using resin).
