Detailed description of the invention
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1-2, the passive cooling system of a kind of mine rescue capsule, comprise the air channel 8 for transporting cold wind be arranged in personnel compartment 13 and the concrete foundation 2 be arranged on outside personnel compartment 13, the one end in described air channel 8 is closed, the other end connects Manual fan 11 and return air inlet 12 in order, air channel is provided with multiple gas distributor 9, air channel 8 is provided with condensation-water drain 7; Condensation-water drain 7 is connected with one-way water outlet valve 5 downwards through personnel compartment base plate 6 by explosion-proof interface 4, for being discharged out of my cabin by condensed water, reduces cabin humidity.
Be embedded with heat sink 14 in concrete foundation 2 and be connected with heat sink 14, part is embedded in heat pipe 1 in concrete foundation 2 in advance.Described heat pipe 1 is positioned at the surface of concrete foundation 2 part and heat sink 14 is coated with heat conductive silica gel or heat-conducting silicone grease on the surface as heat-conducting medium.The depth of burying of heat sink 14 is not less than 1m.Described heat pipe 1 to be entered in personnel compartment by the explosion-proof interface 4 that personnel compartment base plate 6 is arranged and passes in air channel 8, and the top that heat pipe 1 is positioned at air channel 8 is directly arranged with the radiating sleeve 10 of metal material.Apply between radiating sleeve 10 and heat pipe 1 contact surface or be filled with silica gel as thermal conducting agent.Described heat pipe 1 exposes in the part outside personnel compartment 13 and is enclosed with fireproof collet 3.
Heat pipe 1 comprises the tube 102 closed one end, the fin part 103 of the one end being positioned at concrete foundation 2 and capillary wick 101, fin part 103 comprises the ring-type fin of some hollows that be communicated with tube, that manage and be arranged on middle pipe periphery in bottom end closure, tube 102, middle tube cavity and fin cavity interconnect, be filled with a small amount of low-boiling point liquid in it, capillary wick 101 is arranged at the cavity of this connection.
In survival capsule use procedure, personnel and the continuous heat release of equipment in it, the temperature of personnel compartment 13 can constantly rise, the temperature of concrete foundation 2 is then relatively low, tube 102 top that therefore heat pipe 1 can be positioned at personnel compartment 13 is considered as evaporation ends, and the fin part 103 be embedded in concrete foundation 2 is considered as condensation end.When tube 102 top being positioned at air channel 8 be subject to radiating sleeve 10 heat transfer reach uniform temperature time, the low-boiling point liquid of its inside can be vaporized, the heat of air in air channel 8 has been siphoned away while vaporization, steam after vaporization moves along cavity, and distribute in fin part 103 inside, condensation on the limit wall of fin part 103 inside, condensed liquid gets back to tube 102 top along capillary wick 101 under the effect of capillary attraction, and distribute therein, flow to phase transformation generation area, meet the liquid supply required for liquid evaporation, thus form complete circulation, refugee only need shake Manual fan 11 and can be transported in personnel compartment 13 by gas distributor 9 by cold air, realize the continued down to personnel compartment 13.Due to the existence of capillary wick 101, the circulation of liquid is passive, does not need extraneous power, and can work under antigravity.
The above embodiments are the principle of illustrative the invention and effect thereof only, and the embodiment that part is used, but not for limiting the utility model; It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
