Abstract
The utility model discloses a loop heat pipe with a channel heat pipe section used as a condenser. The loop heat pipe mainly comprises three core components of an evaporator, a compensation chamber and the condenser. The three core components are connected together through stainless steel flexible pipes to form a loop. For overcoming the defects that a traditional S-shaped coil condenser is large in size and high in weight, in the design of the condenser, the characteristics that a channel heat pipe is large in heat exchange area and high in heat exchange efficiency are considered fully, the channel heat pipe section is improved to serve as the condenser of the loop heat pipe, and therefore the weight and the size of the condenser are greatly reduced.
Description
Technical field
This patent relates to a kind of loop heat pipe, is specifically related to a kind of loop heat pipe of making condenser by conduit heat pipe section, and it is applied to ground and Space Facilities heat radiation.
Background technology
Loop heat pipe is a kind of passive type two-phase heat transmission equipment efficiently, is mainly used to solve the heat dissipation problem of ground and spacecraft parts, equipment.Along with fast development domestic, external space technology, the load of spacecraft is increasing in recent years, and power consumption also progressively increases, and traditional cooling technology cannot meet the demand of large cold.Quarter-phase circuit cooling technology becomes the optimal selection addressing this problem efficiently.
The condenser that traditional loop heat pipe uses is that flexible stainless steel tube or copper pipe are bent into serpentine coil, is then welded direct on copper cold drawing.But owing to being subject to bending curvature and the larger impact of welding thermal contact resistance, the size of such serpentine coil condenser is larger, and weight is heavier, be not easy to install in spaceborne layout, and thermal resistance is larger, condensation ability is poor, thereby causes the performance of loop heat pipe to reduce.
Goal of the invention
The object of this patent has been to provide a kind of loop heat pipe of making condenser by conduit heat pipe section, is to solve that conventional circuit heat pipe condenser size is large, Heavy Weight, problem that condensation efficiency is low.
This loop heat pipe has evaporimeter 1, compensated chamber 2, condenser 3, liquid line 4, gas piping 5 and forms loop.Evaporimeter 1 directly links together with compensated chamber 2, in evaporimeter 1, contains liquid-sucking core.By gas piping 5, evaporimeter 1 and condenser 3 are linked together, condensation 3 is connected to form loop by liquid line 4 with compensated chamber 2.
Described condenser 3 adopts " Ω " type conduit heat pipe section of aluminium, and at inwardly processing one cavity collecting in order to liquid refrigerant 3.4 of liquid outlet end, conduit inside heat pipe in the inner one end near liquid line 4 and cavity 3.4 of condenser adds one to stop that steam directly enters into the stainless steel sprue 3.1 of liquid line 4 by vapor chamber 3.2, install additional respectively at the two ends of condenser 3 one be convenient to gas, liquid line imports and exports with condenser the stainless steel joint connector 6 being connected.
Beneficial effect:
In the design of condenser 3, take into full account that conduit heat pipe heat exchanging ability is strong, the height of heat exchange efficiency, also improved as the condenser of loop heat pipe by conduit heat pipe section.Reduce weight and the size of condenser, greatly reduced the weight in whole loop, also improved the condensation ability of condenser simultaneously.
Accompanying drawing explanation:
Fig. 1: use the loop heat pipe overall construction drawing of conduit heat pipe as condenser.
Fig. 2 (a): conduit heat pipe condenser structure chart.
Fig. 2 (b): conduit heat pipe section sectional view.
The specific embodiment:
Now by reference to the accompanying drawings this patent is elaborated.
As shown in Figure 1, be the overall construction drawing of this patent.The critical piece of loop circuit heat pipe is evaporimeter 1, compensated chamber 2, condenser 3, and by liquid line 4, gas line 5, and joint connector 6 couples together 1,2 and 3 three parts to form loop.Liquid line through compensated chamber 2, is deep in the core of capillary wick of evaporimeter 1 inside, and together with compensated chamber 2 is welded direct to evaporimeter 1.
In the time that this loop heat pipe condenser 3 is reduced to the temperature of normal work, liquid refrigerant enters into the core of the capillary wick of evaporimeter 1 by liquid line 4, and capillary wick is infiltrated.Evaporimeter 1 is applied to thermic load, and liquid refrigerant, in the outer surface vaporization of capillary wick, by the axial gas conduit in capillary wick, forms superheated steam in the process by axial gas conduit, and superheated steam enters into condenser 3 by steam pipe line 5.In condenser 3, superheated steam cooling condensation gradually in vapor chamber, the condensate liquid of formation enters into " Ω " conduit 3.3.Due to sprue 3.1, steam can not directly pass through condenser air chamber, but promote condensate liquid, along " Ω " conduit 3.3, to flow to condensate liquid collector groove 3.4 excessively cold.The supercooled liquid forming flow in the capillary wick core of evaporimeter 1 along liquid line 4, thereby completes a cyclic process.Unnecessary liquid working substance flows into compensated chamber 2, can guarantee like this capillary wick complete wetting in evaporimeter 1.
