Description
Technical field
The present invention relates to heat transfer technology, specifically refer to a kind of double evaporators loop circuit heat pipe of a shared compensator, it can be applied to the heat radiation of ground and Space Facilities.
Background technology
Loop circuit heat pipe is mainly used in the heat radiation of ground and Space Facilities.When loop circuit heat pipe is applied to require than the heat radiation of higher big plane to temperature homogeneity, use the loop circuit heat pipe of single long evaporimeter will be difficult to the inhomogeneity requirement of satisfied temperature.Because when evaporimeter is long, gaseous working medium is very big at the resistance of evaporimeter internal flow, thereby cause axially having very big gas pressure intensity gradient along evaporimeter, this can influence along the boiling point of the axial working medium of evaporimeter, finally can cause evaporator surface thermograde vertically excessive, thereby influence the temperature homogeneity on big plane, but single long evaporimeter is divided into two evaporimeters just can be addressed this problem, short evaporimeter can reduce the resistance of gaseous working medium in the evaporimeter internal flow, guarantee the temperature homogeneity of each evaporator surface, thereby can satisfy the uniformity requirement of big plane heat radiation.
When the loop circuit heat pipe that uses the single compensator of single evaporator was tested on ground or used, its operation characteristic will be subjected to the restriction of gravitational field in addition.Especially when compensator was in the evaporimeter below, its startability can be subjected to great influence, but is to use the double evaporators structure of a shared compensator will solve this difficult problem.Because no matter how evaporimeter and compensator vertically arrange an evaporimeter all being arranged below compensator, can overcome arrangement in the gravitational field to the influence of loop circuit heat pipe startability.It is that two evaporimeters can backup each other that this design also has an advantage.Owing to formed two loops, when an evaporimeter lost efficacy, can form an independent loop between another one evaporimeter and the condenser, still can independent operating, can improve the reliability of system, increase the service life.
Summary of the invention
The double evaporators loop circuit heat pipe that the purpose of this invention is to provide an a kind of shared compensator.Its main feature is: two evaporimeters are shared compensator; Compensator is placed on the centre of two evaporimeters, and the inner liquid skirt of " fourth " font that uses of compensator is introduced two evaporimeters respectively with working medium; Two evaporimeters use porous material with the transmission of the working medium between realization and the compensator respectively; Single evaporimeter uses a gas line to connect together with condenser, uses two gas lines altogether.This design can overcome on the one hand uses the loop circuit heat pipe of single long evaporimeter to cause the evaporator surface axial temperature inhomogeneous; And can realize backup mutually between two evaporimeters, improve the reliability of system; Loop circuit heat pipe based on this evaporimeter design of Compensator mode can guarantee it is not subjected to the orientation when moving in gravitational field restriction in addition.
The technical solution used in the present invention is as follows:
A kind of double evaporators loop circuit heat pipe of a shared compensator comprises: by two evaporimeters 1 and the evaporimeter compensator assembly that compensator 2 is formed; Article one, liquid line 4 connects condenser 5 and compensator 2; Single evaporimeter 1 uses a gas line 3 and condenser 5 to connect, and has two gas lines 3, forms two loops.
A kind of double evaporators loop circuit heat pipe of a shared compensator is characterised in that:
Two evaporimeter 1 shared compensators 2, its compensator 2 are placed in the middle of two evaporimeters 1, and realization liquid refrigerant transmission between inferior imbibition core 1-2 that all forms by porous material of each evaporimeter 1 and the compensator 2.
" T-shaped " liquid skirt 1-3 of its compensator 2 inner uses feeds the main imbibition core 1-1 of two evaporimeter inside respectively, thereby guarantees can enter two evaporimeters 1 respectively from the working medium of condenser 5.
Advantage of the present invention is as follows:
(1), use the double evaporators of a shared compensator to replace the structure of single compensator single evaporator, it is inhomogeneous to overcome the evaporator surface axial temperature that the loop circuit heat pipe that uses single long evaporimeter causes.
(2), use the double evaporators project organization of a shared compensator, each evaporimeter all is connected to condenser by independent gas line, formed two loops like this, single evaporimeter lost efficacy does not influence the operation of residue evaporimeter, can improve the reliability of whole system.
(3), use the double evaporators project organization of a shared compensator, can guarantee when gravitational field moves, when vertically arranging evaporimeter compensator assembly, can guarantee that all the time an evaporimeter below condenser, can weaken the influence of gravitational field to the loop circuit heat pipe startability.

The specific embodiment:
Now the present invention is described in detail in conjunction with the accompanying drawings.
As shown in Figure 1, be overall construction drawing of the present invention, comprise by two evaporimeters 1 and the evaporimeter compensator assembly that compensator 2 is formed, article one, liquid line 4 connects condenser 5 and compensator 2, single evaporimeter 1 uses a gas line 3 and condenser 5 to connect, have two gas lines 3, form two loops.
When the loop circuit heat pipe described in the present invention is worked.Design an amount of working medium filling weight, to guarantee having liquid to exist in the compensator 2 all the time, under the effect of silk screen or porous material 1-2, main imbibition core 1-1 will be finally soaked in liquid work.Respectively two evaporimeters 1 are added the heat that adds that is not less than minimum starting power, the then working medium of evaporimeter 1 inside gasification, gaseous working medium flow back into condenser 5 along separately gas line 3 then, in condenser 5 inner liquefy working medium, and flow to compensator 2 inside along liquid line 4, thereby realize the startup of loop circuit heat pipe.
After loop circuit heat pipe starts, the liquid refrigerant that flows out from condenser 5 flows into compensator 2 along liquid line 4, under the effect of compensator 2 inside " T-shaped " liquid skirt 1-3, liquid refrigerant is divided into two strands, flow into 1-1 in the main imbibition core of two evaporimeter 1 inside respectively, replenish liquid refrigerant, guarantee the normal operation of whole loop circuit heat pipe because of the heating and gasifying loss.
When an evaporimeter 1 lost efficacy, remain an evaporimeter and can be used as backup, with compensator 2, condenser 5 and gas line 3, liquid line 4 forms the loop circuit heat pipe of the single compensator of single evaporimeter, still can play the effect of transmitting heat.The backup of meeting between two evaporimeters can improve the reliability of whole loop circuit heat pipe, increases the service life.
