A kind of loop heat pipe-type astronomical telescope focusing surface heating radiator that walks abreast, it is mainly by evaporation cavity 3 (as quarrelling shown in 1), loop pipe 4, heat abstractor 6 is formed, the two ends of loop pipe 4 all communicate with evaporation cavity 3, the passage that they form is vacuum state and is filled with hydraulic fluid, astronomical telescope focusing surface 1 contacts with a chamber wall of evaporation cavity 3 or as one of chamber wall of evaporation cavity 3, the top of loop pipe 4 is condensation segment, heat abstractor 6 is installed on described condensation segment, during concrete enforcement, described heat abstractor 6 or be to loose the 7 heat radiation type structures of forming (as Fig. 2 by radiating fin 601 and heat radiation wind, shown in 3), or be by the import 9 on big envelope 8 and the big envelope 8, the liquid cooling structure that outlet 10 is formed is (as Fig. 4, shown in 5).For the ease of the filling and vacuumizing of hydraulic fluid, can right loop pipe 4 or the appropriate position of evaporation cavity 3 corresponding connecting pipe is installed.
Also can be on loop pipe 4 when specifically implementing in addition,, the bottom of described condensation segment is provided with adiabatic section 11 (as shown in Figure 3).The inside imbibition core of pottery, foaming metal, mesh grid, sintering net, fibre bundle, wire gauze, groove or sintering metal powder also can be installed in loop pipe 4.
The utility model is the vaporization by focal plane inside cavity actuating medium, under the effect of minute-pressure difference, make the gas flow condensation segment, condensed hydraulic fluid is back to evaporation ends, so move in circles and constantly transmit heat, the heat that focusing surface is absorbed constantly is delivered to cooling section, dispels the heat by cooling system again.Its inner hydraulic fluid is the solution-air two-phase can take place change, the state that is in high vacuum less than the predetermined value and the inside cavity of cavity volume 40% substantially at the filling rate of inside cavity.
During concrete enforcement, loop pipe 4 and cavity can adopt soft metal, carbon steel pipe, alloy pipe, stainless-steel tube and other shell material to make, and can be all when adopting the soft metal or predetermined portions through partly or completely annealing softening processing, thereby can be arbitrarily crooked, and adopt carbon steel pipe, alloy pipe, stainless-steel tube equal strength, tubes of material that hardness is big can adopt the mechanical system manufacturing of clod wash or hot bending.
During concrete enforcement, the cavity of evaporation cavity 3 can change its geometric shape and inner-cavity structure according to the needs of actual conditions.
During concrete enforcement, can use also and can not use according to actual conditions inside liquid sucting core structure.The adiabatic section is also not essential, and evaporator section and condensation segment can change according to actual conditions.Can also electroplate or spraying enhanced rad material figure layer at bringing-up section, adiabatic section, cooling section tube wall.

In addition, when specifically implementing, also an exhausr port can be set on the loop pipe, this exhausr port can be the form of solder up or renewable valve.
The moving situation of internal work liquid stream-liquid two-phase flow can change with different operating angle condition decline in different through-put powers, heating radiator can be in the slewing area of 3 °＜θ≤90 ° trouble free service.
The fin form in this heat radiation type heat abstractor 6 can be the type of attachment of ratio-frequency welding fin, mechanical suit fin and other fins and tubing, the type of fin can be evolving forms such as sheet, needle-like, thorn-like.Fin material can be the same with tubing, also can be different with tubing, and also can be the thermally-conductive sheet of other material and profile geometry form.
The parallel heat pipe-type astronomical telescope focal plane heating radiator of loop that this reality has novelly provides that a kind of heat-transfer capability is big, toggle speed is fast, heat flow density is high, heat transfer temperature difference is little, unidirectional heat transfer, long service life, average temperature performance are good, need not additionaling power, the angle usable range is wide.Its first characteristics are to have provided the parallel heat pipe-type astronomical telescope focal plane heating radiator of a kind of loop, can effectively solve the heat radiation difficult problem of large-scale astronomical telescope focusing surface.Second characteristics have been to provide the version of the parallel heat pipe of a kind of loop, it can be under very little angle (0 angle) condition steady operation, overcome the phenomenon of thermal siphon work unstability, the heat transfer deterioration phenomenon appears dryouting etc. in heat pipe evaporator section.The 3rd characteristics are that loop parallel heat pipe-type astronomical telescope focal plane heating radiator has overcome the situation that thermal siphon can not steady operation when the equipment work angle constantly changes condition.The 4th characteristics are to utilize the version of the parallel heat pipe of loop, overcome the little problem that can't arrange heat dissipation element in device interior space, and heat delivered to device external, is expanded area of dissipation, help selecting suitable heat dissipating method according to different conditions.
Because heating radiator is along with the telescope cylindrical shell rotates in ° scope of 3 °＜θ≤90, therefore, the axis of heating radiator evaporation cavity and the angle of surface level also change between 3 °～90 °.When θ=90 °, hydraulic fluid is full of the wedge angle that 45 ° of inclined-planes form fully, and focal plane is submerged under the hydraulic fluid; When the increase of θ along with angle, hydraulic fluid is owing to the effect of gravity, and the area of submergence focal plane reduces gradually; When θ equaled 3 °, it is minimum that the area of submergence focal plane reaches, as shown in Figure 2.The height change of liquid level causes the evaporation of liquid temperature to change, and then has influence on the focusing surface hot-fluid and also change.
The power that liquid refluxes in the loop parallel type heat pipe at the component along the pipe range direction, also is subjected to the frictional resistance of steam and wall from the condensed fluid self gravitation simultaneously, and cold and hot two sections acting forces owing to the pressure reduction generation.Because the continuous variation from big to small of the operating angle of heating radiator makes the component that refluxes also along with changing from big to small.Low-angle the time since the component of gravity much larger than its residual resistance sum, pipe surface temperature and variation tendency unanimity; When wide-angle, the component of condensed fluid gravity during less than its residual resistance sum top pipe wall surface temperature be higher than bottom pipe wall surface temperature, hydraulic fluid forms big looped cycle at tube cavity, and steam then is back to evaporator section by the bottom pipe by the mobile condensed fluid of top pipe.
