Description
Technical field
The invention belongs to thermal control fields, are related to capillary pump used in a kind of loop circuit heat pipe, especially this kind of loop circuit heat pipe
Component.
Background technique
Loop circuit heat pipe (LHP) is the two-phase fluid circuit system that heat exchange is completed using capillary power drive working medium circulation, it is logical
It crosses flexible pipeline and heat from heat source is quickly transmitted to heat sink, flexibility needed for flexible conduit is applicable to rotation/moving heat source
Heat transfer link has many advantages, such as that heat transfer temperature difference is small, heat power is big, heat transfer distances are remote, temperature-controlled precision is high and flexible for installation.Base
In this, loop circuit heat pipe has become a kind of advanced in accurate thermal control system and has accurate thermal control production with broad prospects for development
Product, working principle are as shown in Figure 1.
Starting characteristic, heat-transfer capability and the reliability of service life of loop circuit heat pipe are performance ginsengs mostly important in its engineer application
Number." heart " of the capillary pump assembly as loop circuit heat pipe, rational Design on Plane are the key that determine above three performance indicator.
It is that loop circuit heat pipe smoothly starts and stable operation that capillary wick in capillary pump assembly is sufficiently infiltrated by liquid working substance
Necessary condition.Currently, the capillary wick of domestic cylindrical type capillary pump assembly is only arranged in evaporator, when Ground Application, can lead to
Adjustment capillary pump posture is crossed, liquid flows by gravitational force into evaporator to guarantee that capillary wick infiltrates；And under in-orbit microgravity environment,
Most liquid are randomly distributed in liquid storage device in droplet form, and capillary wick has locally dry possibility in evaporator at this time, this
The risk that loop circuit heat pipe will be made to there is starting failure or outage.Foreign countries are connected to evaporator by adding secondary capillary wick at present
With liquid storage device, i.e., secondary capillary wick one end is inserted into main capillary wick and (is located inside evaporator) inside, and the two fits closely, and the other end is deep
Enter in liquid storage device, collect liquid and is sent to main capillary wick.But this assembly method is used, major and minor capillary wick assembly difficulty is big,
And secondary capillary wick and main capillary wick connecting portion outer diameter are small, mechanical property is poor, and in Spacecraft Launch section, there are the risks of injured.
In addition, both at home and abroad a large number of studies show that, (degree of superheat) loop when evaporator is higher by certain value than liquid storage device temperature
Heat pipe could normally start.However when evaporator is heated, heat can pass through capillary pump assembly shell and the thermally conductive biography of capillary wick
Liquid storage device is passed, liquid storage device temperature rises with it, and the degree of superheat is difficult to be formed, and leads to loop circuit heat pipe starting failure；Or the degree of superheat
Overlong time is formed, loop circuit heat pipe delay start limits its engineer application range.
The maximum heat transport capability of loop circuit heat pipe directly depends on the micropore size and porosity of capillary wick in capillary pump assembly,
The chemical stability of capillary wick own material is also to determine the principal element in loop circuit heat pipe service life simultaneously.Capillary wick effective apearture hole
Diameter is smaller, and the REFRIGERATION SYSTEM DRIVEN BY CAPILLARY FORCE power provided is bigger, and open-cell porosity is bigger, and flow resistance is smaller inside capillary wick, i.e. small-bore, large opening
The capillary wick of porosity can make loop circuit heat pipe have bigger heat-transfer capability.Mostly use the metal materials such as nickel, titanium both at home and abroad at present
Prepare capillary wick.In blank, capillary wick can guarantee lesser aperture and big open-cell porosity, however add in surface machinery
In working hour, since metal material ductility is big, turning or wire cutting will lead to surface micropore closure, reduce open-cell porosity.Separately
On the one hand, capillary wick is as porous media, and effective surface area accounts for the exhausted large scale of loop circuit heat pipe inner wall area, and metal material
Relative activity is higher, poor with working medium compatibility, causes working medium decomposition rate to increase, reduces loop circuit heat pipe service life.
