Fig. 2 is the local annexation sketch map of water pipeline 2 and phase-change working substance heat release section 3 among Fig. 1.
Fig. 3 is the enlarged diagram of water pipeline 2 and phase-change working substance heat release section 3 among Fig. 1.
Fig. 4 is the structural representation of a plurality of water pipeline 2 polyphones.
The specific embodiment: shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, present embodiment comprises domestic gas hot water apparatus main frame 7 and secondary machine 5.Domestic gas hot water apparatus main frame 7 is installed in outdoor, and secondary machine 5 is installed in the environment temperature higher position.
Be provided with main frame heat exchanger 4 and burner 1 in the domestic gas hot water apparatus main frame 7, main frame heat exchanger 4 is installed in the high-temperature flue gas exit of burner 1.Secondary machine 5 is provided with secondary machine heat exchanger 6; Secondary machine heat exchanger 6 comprises water pipeline 2 and phase-change working substance heat release section 3; Water pipeline 2 directly or indirectly contacts with phase-change working substance heat release section 3, and main frame heat exchanger 4 is communicated with the back and forms the complete heat pipe on the thermodynamic significance with phase-change working substance heat release section 3.
Can dash the refrigerant that uses in the refrigeration air-conditioner of irritating conventional in the main frame heat exchanger 4, like common ammonia, R134a etc., main frame heat exchanger 4 internal pressures are higher than atmospheric pressure under the room temperature at this moment; Also can dash and irritate hot superconduction phase-change working substance, it is fast that the superconduction phase-change working substance has axial heat conduction speed, and radiation loss is few; The characteristics of environment-friendly high-efficiency; Its freezing point is the enhance heat transfer effect far below 0 ℃, and main frame heat exchanger 4 internal pressures must be lower than atmospheric pressure under the room temperature; Be vacuum state, disclosed similar superconduction phase-change working substance has following document: the CN200410003982.6 heat transfer medium; The CN90104025.8 energy-saving high efficient heat tranfer device; The heat-pipe working medium that CN1102200 is made up of inorganic material; CN1051750 Lnoganic medium heat-conducting material or the like.In the present embodiment, main frame heat exchanger 4 is the cavity of vacuum for being equipped with under the hot phase-change working substance normal temperature of superconduction (25 ℃).
During installation; Secondary machine 5 is installed in the environment temperature higher position; As indoor or install the outdoor of protection attemperator additional, because phase-change working substance has lower freezing point, so it can avoid in the heat exchanger of domestic gas hot water apparatus water pipe to be damaged by frost in environment temperature lower (being lower than 0 ℃) time.Domestic gas hot water apparatus main frame 7 can be installed in indoor or outdoor.
Between main frame heat exchanger 4 and phase-change working substance heat release section 3, the return duct that is communicated with both can be set.
Secondary machine heat exchanger 6 can be double pipe heat exchanger, plate type heat exchanger, plate-fin heat exchanger or shell-and-tube heat exchanger; Secondary machine heat exchanger 6 is a double pipe heat exchanger among the present invention; Water pipeline 2 can encase phase-change working substance heat release section 3 in the secondary machine heat exchanger 6, but also phase-change working substance heat release section 3 encases water pipeline 2.
Secondary machine heat exchanger 6 can be copper product, aluminum or stainless steel material and processes.
Secondary machine heat exchanger 6 can be provided with plural water pipeline 2 and the phase-change working substance heat release section 3 that matches, and between the adjacent phase-change working substance heat release section 3 and downlink connection, can contact between the adjacent water pipeline 2 connects or and downlink connection.
Main frame heat exchanger 4 can be installed in burner 1 above or below.
Main frame heat exchanger 4 can be provided with fin with enhanced heat exchange.
During the work of domestic gas hot water apparatus, the gas ignition burning of burner 1 ejection produces high-temperature flue gas; High-temperature flue gas contacts with main frame heat exchanger 4 in flowing; Discharge from flue becoming low-temperature flue gas behind the heat transferred main frame heat exchanger 4, main frame heat exchanger 4 is again with the phase-change working substance in the heat transferred chamber, and phase-change working substance is heated and vaporizes rapidly; With the secondary machine heat exchanger 6 of heat transferred; The water that secondary machine heat exchanger 6 need heat heat transferred again, phase-change working substance is back in the main frame heat exchanger 4, is heated once more.So circulation adopts phase-change working substance as heat transfer medium, between flue gas and water, transmits heat, and the heat that main frame heat exchanger 4 is absorbed passes to the water that needs heating through secondary machine heat exchanger 6.
Be the heat transfer load of the heat exchanger that increases the domestic gas hot water apparatus, thereby strengthen the power of domestic gas hot water apparatus, main frame heat exchanger 4 can be communicated with a plurality of secondary machine heat exchangers 6 through pipe.
Main frame heat exchanger 4 and secondary machine heat exchanger 6 split settings; The water that the secondary machine heat exchanger 6 of the heat transferred of main frame heat exchanger 4 absorptions is used for heating secondary machine heat exchanger 6 through hot superconduction phase-change working substance; Because it is fast that hot superconduction phase-change working substance has axial heat conduction speed; The characteristics that radiation loss is few, so it can reduce the loss of the hot water heat of domestic gas hot water apparatus heating effectively, also can reach main frame heat exchanger 4 with secondary machine heat exchanger 6 distances the far away and less effect of hot water thermal loss.
Owing to constituted split type domestic gas hot water apparatus; Realized the isolation of burner and water-heating device; Also can preventing leaks causes damage to burner and circuit control device, and domestic gas hot water apparatus main frame 7 is installed in and has also reduced the potential hazard that combustion gas is revealed with CO discharges and combustion noise causes the user when outdoor.
