Brief description of the drawings
Fig. 1 is the structural representation of the northeast adobe kang system of the utility model based on pulsating heat pipe heat exchange;
Fig. 2 is the utility model two-phase closed type pulsating heat pipe loop works structure and mechanism schematic diagram.
Detailed description of the invention
As shown in Figure 1, pulsating heat pipe heat-exchange system, comprises smoke chamber 6, heat-exchanging chamber 9, some pulsation suction pipes, the top of heat-exchanging chamber in smoke chamber 6; Smoke chamber 6 is provided with gas approach and exhanst gas outlet; Heat-exchanging chamber is provided with water inlet and delivery port; Some pulsating heat pipes form closed circuit, and a part for pulsating heat pipe is placed in heat-exchanging chamber (this is pulsating heat pipe cooling section), and another part is placed in smoke chamber (this is pulsating heat pipe evaporator section).The flue gas that fuel combustion is discharged is flowed out by kitchen range top main body 2, via flue 3, enters fume sedimentation chamber 5.4 is flue exterior wall.Flue gas enters in the smoke chamber 6 of pulsating heat pipe heat-exchange system from fume sedimentation chamber flows out, and is discharged and is entered chimney by smoke chamber exit 8 after the heat exchange of pulsating heat pipe evaporator section.Condensed water in smoke chamber flows out via condensation-water drain 7.The condensation segment of pulsating heat pipe is placed in heat-exchanging chamber, and for heating domestic water, domestic water, by pipeline section 10, flows into and is stored in kitchen water tank 1.Dust chamber 5 is positioned at kitchen range top smoke outlet, utilizes gravitational dust collection principle, and sedimentation flue dust is also regularly removed.The water inlet of heat-exchanging chamber connects the delivery port of running water pipe; The delivery port of heat-exchanging chamber connects the water inlet pipe of kitchen water tank; The gas approach of smoke chamber 6 connects the smoke outlet of the kitchen range top; The smoke outlet of smoke chamber 6 meets the smoke inlet place of chimney; Smoke chamber 6 bottoms are provided with condensed water delivery port.
As shown in Figure 2, the caliber very little (internal diameter is generally at 0.53mm) of pulsating heat pipe, it is to bend to back-shaped structure by metal capillary, pipe bend one end is fire end (evaporator section), the other end is colling end (condensation segment), can arrange as required adiabatic section in centre.Pipe inside is evacuated, and fills hydraulic fluid.When pulsating heat pipe work, bringing-up section (evaporator section) and cooling section (condensation segment) are respectively at pipeline section two ends, and generally, evaporator section is in bottom, and cooling section is on top.Pulsating heat pipe when work, because caliber is enough little, in pipe, will form bubble column 11 and liquid column 12 intervals and arrange and be the state of random distribution.At evaporation ends, working medium heat absorption produces bubble, expands rapidly and boosts, and promotes working medium and flows to the pressure imbalance existing between adjacent pipe, makes working medium between evaporation ends and condensation end, form gas-liquid post vibration 13, thereby realizes the transmission of heat.In whole process, without consuming exterior mechanical merit and electric work, be the oneself's concussion under heat drives completely.And its evaporator section and condensation segment separate described pulsating heat pipe by a thermal baffle, on evaporator section (being arranged in the part of smoke chamber), some fins 14 are housed, to increase heat exchange area, enhanced heat exchange.
Therefore pulsating heat pipe has following structure and feature:
1) centreless simple in structure, shape can be bending arbitrarily, and equivalent heat transfer coefficient is large, and volume is little, and high heat flux is a kind of high-performance heat transfer components of miniaturization.
2) the cold and hot section of fluid that participates in heat exchange in heat pipe, all in pipe flows outside, makes flow resistance little, and adds fin reinforcement heat transfer.
3) different from conventional heat pipe, pulsating heat pipe inside is without liquid-sucking core material, thereby it is simple in structure, easy to manufacture, with low cost.
4) heat pipe is via twice wall heat exchange, ne-leakage, and Cooling and Heat Source fluid can not mix mutually.
Therefore to have heat transfer temperature difference little for pulsating heat pipe, and the feature such as heat transfer coefficient is large, and flow resistance is little, there is no seepage, simple in structure, with low cost, so be applicable in the utility model type technical scheme high efficient heat exchanging.
The course of work of the present utility model is: the high-temperature flue gas that fuel combustion produces is by after the kitchen range top, enter into smoke chamber 6 by flue, carry out heat exchange with pulsating heat pipe, pulsating heat pipe is used for the heat after absorbing to the cool water heating in heat-exchanging chamber by cooling section, thereby reaches the effect of Mist heat recovering.Flue gas by heat pipe after the condensed water of condensation can absorb part NOx and the SOx in flue gas, discharge via condensation-water drain 7.In addition flue gas carries out gravity type dedusting entering before heat-exchanging chamber, can play protection of the environment with original system ratio, alleviates the effect of haze.
