Embodiment

Embodiment 1.

In Fig. 1 and Fig. 2, the vacuous solar energy water distillation apparatus of the external additional prolong of evaporation channel, comprises solar energy evacuated heat collector tube element, heat transfer jacket comb, adiabatic water tank 1 and support.Solar energy evacuated heat collector tube element comprises that all-glass vacuum thermal-collecting tube 2 and insertion all-glass vacuum thermal-collecting tube 2 pass hot linked copper water heat pipe 3; Adiabatic water tank 1 comprises bucket 4 in tank shell, thermal insulation layer, water tank, excessive tracheae and passes in and out water barge to be taken over.Heat transfer jacket comb is placed in the thermal insulation layer of adiabatic water tank 1.Heat transfer jacket comb comprises the heat transfer sleeve pipe 5 of several blind pipe structures, and inner the realization with the heat transfer of evaporation runner 6 interior water of evaporation runner 6 that heat transfer sleeve pipe 5 blind ends stretch into a placed horizontally is connected.The open end that the cold junction 7 of heat pipe 3 inserts heat transfer sleeve pipe 5 coordinates heat transfer to be connected with heat transfer sleeve pipe 5.

Adiabatic water tank 1 contains a built-in prolong 8, and the import of built-in prolong 8 and outlet are communicated with evaporation runner 6 and an additional prolong 9 respectively.Additional prolong 9 is a corrugated tube, is placed in adiabatic water tank 1 below.The other end of additional prolong 9 is taken over 10 with distillation water barge and is communicated with.Water in adiabatic water tank 1 enters evaporation runner 6 through filling pipe 11 and an evaporation runner level control valve 12.And keep the liquid level of water to be distilled all the time in inner approximately 1/3rd height of evaporation runner 6; The space of two height that evaporation runner 6 its excess-three are divided is as steam flow channel.

The principle of work of embodiment 1: sunlight is converted to heat energy through the absorbing film on vacuum heat collection pipe 2 inner glass tube surfaces and thermal energy transfer is arrived to cold junction 7 and through the water in heat transfer sleeve pipe 5 heating evaporation runners 6, made it constantly to evaporate mineralization pressure and enter the built-in prolong 8 in adiabatic water tank 1 a little more than the steam of barometric point by vapor communication pipe 14 by heat pipe 3 hot junctions 13 of inserting wherein.In adiabatic water tank 1, possess enough water yields, steam condenses into distilled water through built-in prolong 8 and the water heat exchange in adiabatic water tank 1 and emits heat and the water in adiabatic water tank 1 is heated up.Distilled water is taken over 14 through distillation water barge and is led to the indoor water butt of user.

When summer hot water rate of utilization very few, the interior water temperature of adiabatic water tank 1 is higher, can not fully provide the cooling power of steam time, it is further cooling that additional prolong can provide.To add 2 meters of condensation section length, 0.5 square metre of area of dissipation, 50 DEG C of heat transfer temperature differences, the coefficient of heat transfer 20 kilocalories/when * (square metre * Δ DEG C) meter, heat-sinking capability is 500 kilocalories/time.The water distillation apparatus of 20 thermal-collecting tubes, maximum thermal-arrest ability approximately 800 kilocalories/time.

Additional prolong should be got dull decline and arrange, guarantees that inner water is enough few.
