DETAILED DESCRIPTION

[0038] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] like Figure 1~Figure 4 As shown, this embodiment proposes

[0040] A closed gas internal combustion heater, comprising:

[0041] Bracket 1,

[0042] The combustion chamber 2 is arranged on the bracket 1.

[0043] The heat dissipation chamber 3 is arranged on the bracket 1 and communicated with the combustion chamber 2. The heat dissipation chamber 3 has an exhaust gas outlet 4.

[0044] The heat dissipation pipe 18 is wound around the outer wall of the combustion chamber 2 and is connected to the combustion chamber 2.

[0045] The heat exhaust fan 7 is arranged on the bracket 1 and is used to disperse the heat of the combustion chamber 2, the heat dissipation pipe and the heat dissipation chamber 3.

[0046] Furthermore, it also includes:

[0047] There are a plurality of buffer plates 5 which are arranged at intervals in the heat dissipation chamber 3 . The buffer plates 5 are provided with through holes 6 , and the through holes 6 on adjacent buffer plates 5 are arranged in a staggered manner.

[0048] In this embodiment, the combustion of gas in the combustion chamber 2 will generate a large amount of heat and high-temperature exhaust gas containing a large amount of heat. The combustion chamber 2 will quickly heat up and dissipate heat into the surrounding air, and the generated high-temperature exhaust gas will enter the heat dissipation chamber 3 and the heat dissipation pipe 18 connected to the combustion chamber 2. After the high-temperature exhaust gas enters the heat dissipation chamber 3, because the through holes 6 on the buffer plate 5 are staggered, the flow of the high-temperature exhaust gas in the heat dissipation chamber 3 is tortuous rather than straight, which increases the contact area and contact time between the high-temperature exhaust gas and the heat dissipation chamber 3 and the buffer plate 5, so that the heat dissipation chamber 3 can absorb more heat from the high-temperature exhaust gas; the heat dissipation pipe 18 is wrapped around the outer wall of the combustion chamber 2, and a heat dissipation structure is also formed. Then, the heat exhaust fan 7 is used to blow air to the heat dissipation pipe 18 and the heat dissipation chamber 3, thereby increasing the heat dissipation efficiency, improving the heat utilization rate of the gas, and solving the problem of low gas utilization rate of heating equipment in related technologies. Finally, the exhaust pipe can be connected to the exhaust outlet 4 on the heat dissipation chamber to discharge the exhaust gas to the outdoors.

[0049] Furthermore, it also includes

[0050] The temperature sensor 8 is disposed in the heat dissipation chamber 3 , and is used to monitor the temperature of the heat dissipation chamber 3 .

[0051] In this embodiment, a temperature sensor 8 is provided inside the heat dissipation chamber 3 , and the temperature sensor 8 can detect the temperature of the heat dissipation chamber 3 in real time.

[0052] Furthermore, it also includes:

[0053] The ignition needle 11 is arranged in the combustion chamber 2.

[0054] The air supply ring 12 is sleeved around the gas nozzle 9 and has a plurality of air outlet holes 13.

[0055] The oxygen pipe 14 is connected to the air supply ring 12.

[0056] The oxygen enrichment fan 15 is arranged on the bracket 1, and the oxygen enrichment fan 15, the oxygen pipeline 14 and the air supply ring 12 are connected in sequence.

[0057] In this embodiment, the gas pipeline 10 transports the gas to the gas nozzle 9 and releases it to the combustion chamber 2. The oxygen enrichment fan 15 transports air to the air supply ring 12 through the oxygen pipeline 14, and then ejects it through the air outlet 13 surrounding the gas nozzle. At this time, the ignition needle 11 ignites. Because of the continuous supply of fresh air, the gas is burned more fully, further improving the utilization rate.

[0058] Furthermore, it also includes:

[0059] The sensing needle 16 is disposed in the combustion chamber 2 , and is used to monitor the temperature of the combustion chamber 2 .

[0060] In this embodiment, the sensing needle 16 can detect the temperature in the combustion chamber 2 to determine whether the ignition is successful or not. The sensing needle 16 is connected to the solenoid valve that controls the gas pipeline 10. When the gas in the combustion chamber 2 is extinguished due to abnormal reasons, the gas supply can be cut off immediately.

[0061] Furthermore, it also includes:

[0062] The shell 17, the combustion chamber 2, the heat dissipation pipe 18, the heat dissipation chamber 3 and the bracket 1 are arranged inside the shell 17. The top of the shell 17 has an opening, which is located at the top of the combustion chamber 2 and the heat dissipation chamber 3. When the heat exhaust fan 7 blows air, the heat is discharged from the opening; preferably, a through hole can also be opened on the shell 17 for air circulation inside the shell 17.

[0063] In this embodiment, the combustion chamber 2, the heat dissipation pipe 18, the heat dissipation chamber 3 and the bracket 1 are all arranged in the shell 17. An opening is arranged on the shell 17, and the heat is discharged from the opening. The heat discharge is concentrated, and the heating efficiency is better.

[0064] Furthermore, it also includes:

[0065] The gas cylinder 19 is arranged outside the shell 17 and is connected to the gas pipeline 10 , and the gas is supplied to the combustion chamber 2 through the gas cylinder 19 .

[0066] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
