Referring to fig. 1, 2, 3 and 4, as an embodiment of the present invention, the steam generator includes a heating chamber 110 having a hollow structure, and a heat transfer chamber 120 having a hollow structure is fixed to a top of the heating chamber 110. The heating chamber 110 can heat the heat transfer chamber 120. The cavity of the heat transfer chamber 120 stores a heat transfer medium. A first guide means 130 for guiding the flow of water is provided at one side in the heat transfer chamber 120, and a second guide means 140 for guiding the flow of gas is provided at the other side. The first diversion device 130 includes a first water conduit 131 of a linear structure, a second water conduit 132 of a spiral structure, a first connection pipe 133 of an arc structure, a third water conduit 134 of a spiral structure, and a fourth water conduit 135 of a linear structure, which are sequentially connected. An end of the first water introduction pipe 131, which is remote from the second water introduction pipe 132, extends to the outside of the heat transfer chamber 120 through the sidewall of the heat transfer chamber 120, and an end of the fourth water introduction pipe 135, which is remote from the third water introduction pipe 134, also extends to the outside of the heat transfer chamber 120 through the sidewall of the heat transfer chamber 120. The second guiding device 140 comprises a first air duct 141 with a linear structure, a second air duct 142 with a spiral structure, a second connecting pipe 143 with an arc structure, a third air duct 144 with a spiral structure, a fourth air duct 145 with a linear structure and a fifth air duct 146 with a linear structure, which are sequentially communicated, wherein one end of the first air duct 141, which is far away from the second air duct 142, penetrates through the side wall of the heat transfer chamber 120 and extends to the outside of the heat transfer chamber 120; one end of the fifth air duct 146, which is far away from the fourth air duct 145, extends through the top of the heating chamber 110 to the inside of the heating chamber 110.

In this embodiment, the heating chamber 110 is capable of transferring thermal energy to the heat transfer chamber 120. The first deflector 130 is capable of directing water flow and the second deflector 140 is capable of directing gas flow. Wherein, a heat conducting medium is stored in the cavity of the heat transfer chamber 120. The heat transfer medium in the heat transfer chamber 120 is increased in temperature by the heating of the heating chamber 110. When the temperature of the heat transfer medium is greater than 100 ℃, the water flowing through the first deflector 130 can be vaporized. Here, the introduced gas is an exhaust gas generated by combustion in the heating chamber 110. The first flow guiding device 130 increases the contact area of the water and the heat conducting medium in the flow guiding process, and effectively improves the heat conduction efficiency when the heat conducting medium transfers heat energy to the water. Because the waste gas generated by the combustion of the heating chamber 110 has a certain residual temperature, the second guiding device 140 can conduct the residual temperature to the heat-conducting medium in the process of guiding the waste gas, so that the heating medium is heated rapidly. Thus, the heat transfer efficiency of the heating chamber 110 to the heat transfer chamber 120 is effectively improved.

Specifically, the first deflector 130 includes a first water guiding pipe 131 of a straight line structure, a second water guiding pipe 132 of a spiral structure, a first connecting pipe 133 of an arc structure, a third water guiding pipe 134 of a spiral structure, and a fourth water guiding pipe 135 of a straight line structure, which are sequentially connected. Therefore, the heat conduction efficiency of the heat conduction medium for transferring heat energy to water is greatly improved. The second guiding device 140 includes a first air duct 141 with a linear structure, a second air duct 142 with a spiral structure, a second connecting pipe 143 with an arc structure, a third air duct 144 with a spiral structure, a fourth air duct 145 with a linear structure, and a fifth air duct 146 with a linear structure, which are sequentially connected. Thus, the heat transfer efficiency of the heating chamber 110 to the heat transfer chamber 120 is greatly improved. An end of the first water introduction pipe 131, which is remote from the second water introduction pipe 132, extends to the outside of the heat transfer chamber 120 through the sidewall of the heat transfer chamber 120, and an end of the fourth water introduction pipe 135, which is remote from the third water introduction pipe 134, also extends to the outside of the heat transfer chamber 120 through the sidewall of the heat transfer chamber 120. One end of the first air duct 141, which is far away from the second air duct 142, extends to the outside of the heat transfer chamber 120 through the sidewall of the heat transfer chamber 120. One end of the fifth air duct 146, which is far away from the fourth air duct 145, extends through the top of the heating chamber 110 to the inside of the heating chamber 110.

The working principle is as follows: water can flow in from one end of the first water introduction pipe 131, which is far from the second water introduction pipe 132, and heat energy is transferred to the water through the heat transfer medium, so that the flowing water is changed into water vapor and flows out from one end of the fourth water introduction pipe 135, which is far from the third water introduction pipe 134. The exhaust gas generated by the combustion in the heating chamber 110 can flow in from the end of the fifth air duct 146 far away from the fourth air duct 145, and the flowing exhaust gas transfers heat energy to the heat transfer medium and then flows out from the end of the first air duct 141 far away from the second air duct 142.

In an embodiment of the present invention, the end of the first water guiding pipe 131 far from the second water guiding pipe 132 is higher than the end of the fourth water guiding pipe 135 far from the third water guiding pipe 134 in the vertical direction. Thus, in the vertical direction, the inflow point of water is made higher and the outflow point of steam is made lower. The end of the second water introduction duct 132 opposite to the first water introduction duct 131 is lower than the end of the fourth water introduction duct 135 far from the third water introduction duct 134. The power required for water to flow into the first deflector 130 is small, and no additional power source is required. The end of the first air duct 141 remote from the second air duct 142 is higher than the end of the fifth air duct 146 remote from the fourth air duct 145. In this way, in the vertical direction, the inflow point of the exhaust gas is made lower and the outflow point of the exhaust gas is made higher. The end of the first air duct 141 remote from the second air duct 142 is lower than the end of the fifth air duct 146 remote from the fourth air duct 145. The power required by the flowing of the waste gas is small, and no extra power source is needed. The first water guiding pipe 131, the second water guiding pipe 132, the first connecting pipe 133, the third water guiding pipe 134, the fourth water guiding pipe 135, the first air duct 141, the second air duct 142, the second connecting pipe 143, the third air duct 144, the fourth air duct 145 and the fifth air duct 146 are all immersed in the heat transfer medium. Thus, the heat transfer efficiency is further improved.

A heat conductive plate 180 is provided between the top of the heating chamber 110 and the bottom of the heat transfer chamber 120, and the heat conductive plate 180 can isolate the inside of the heating chamber 110 from the inside of the heat transfer chamber 120. One end of the fifth air duct 146, which is far away from the fourth air duct 145, extends through the heat conducting plate 180 to the inside of the heating chamber 110.

Specifically, air is introduced into the heating chamber 110 through the air inlet 170, and gas is introduced into the burner 150 through the gas inlet 160. The heat conductive plate 180 can be heated by burning gas. The heat conductive plate 180 can transfer heat energy to the heat conductive medium. The exhaust gas generated by the combustion in the heating chamber 110 flows into the second guiding device 140 through the end of the fifth air duct 146 far away from the fourth air duct 145. Here, it should be noted that the fuel gas may be natural gas or a mixed gas. The mixed gas is a mixture of natural gas and hydrogen.
