[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] The heater for internal combustion locomotives disclosed in this utility model is mainly applied to scenarios where existing internal combustion locomotive heaters heat liquids by burning fuel, but a large amount of heat energy is lost with the high-temperature exhaust gas and not recovered, resulting in fuel waste and low thermal efficiency.

[0021] Reference Figures 1-3 A heater for internal combustion engine vehicles, comprising: A connecting plate 7 is fixedly connected to a fixing chamber 3 on its upper side. A setting block 8 is embedded in the upper side of the connecting plate 7. A combustion chamber 12 is fixedly connected to the lower side of the connecting plate 7. A water heating chamber 11 is fixedly connected to the lower side of the connecting plate 7. The combustion chamber 12 is located inside the water heating chamber 11. A water outlet pipe 16 and a water inlet pipe 17 are respectively provided on the outer walls of both sides of the fixing chamber 3. The water inlet end of the water outlet pipe 16 and the water outlet end of the water inlet pipe 17 pass through the connecting plate 7 and are connected to the interior of the water heating chamber 11. The exhaust pipe 14 is located on one side of the outer wall of the fixed chamber 3, and the air inlet end of the exhaust pipe 14 passes through the mounting block 8 and connects to the interior of the combustion chamber 12. The heat recovery and utilization component 6 is installed on the outer wall of the fixed chamber 3. The heat recovery and utilization component 6 is used to utilize the hot exhaust gas generated by the combustion chamber 12, thereby providing heat compensation and preheating for the water outlet pipe 16 and the water inlet pipe 17.

[0022] Reference Figures 1-5 In a preferred embodiment, the heat recovery and utilization component 6 includes: The adjusting rod 609 is connected to the adjusting hole opened on the inner wall of the air outlet end of the air outlet pipe 14 via a bearing. The adjusting plate 608 is fixedly connected to the outer wall of the adjusting rod 609 and is located inside the air outlet pipe 14. The adjusting motor 607 is fixedly connected to the outer wall of the fixed chamber 3 near the air outlet pipe 14. The drive end of the adjusting motor 607 is connected to one end of the adjusting rod 609 through a coupling. Filter chamber 605, two filter chambers 605 are respectively fixedly connected to the fixed chamber 3 on the side near the water outlet pipe 16 and the water inlet pipe 17; Temperature detector 601 is installed on the outer wall of the outlet end of water pipe 16.

[0023] In this solution, the heat recovery and utilization component 6 also includes: The inlet end of the diverter pipe 606 is inserted into the outer wall of the outlet end of the outlet pipe 14, and the two outlet ends of the diverter pipe 606 are respectively inserted into the outer walls of the two filter chambers 605. Rotating shaft 611, multiple rotating shafts 611 are connected at equal intervals to the inside of two filter chambers 605 via bearings, and activated carbon rotating plates 612 are fixedly connected to the outer walls of the two rotating shafts 611 located in the same filter chamber 605.

[0024] In this solution, the heat recovery and utilization component 6 also includes: The air supply pipes 603 are respectively inserted into the outer wall of the corresponding filter chamber 605 at the end away from the diversion pipe 606. Heating sleeves 602 are fixedly connected to the outer walls of the two sides of the fixed chamber 3. The two heating sleeves 602 are respectively sleeved on the outer wall of the water outlet end of the water outlet pipe 16 and the outer wall of the water inlet end of the water inlet pipe 17. The air outlet ends of the two air supply pipes 603 are respectively connected to the interior of the corresponding heating sleeves 602.

[0025] In this solution, the heat recovery and utilization component 6 also includes: Slow-flow baffles 610, multiple slow-flow baffles 610 are fixedly connected to the inside of two heating sleeves 602 respectively, and multiple vent holes are opened on one side of the multiple slow-flow baffles 610 located in the same heating sleeve 602 and are arranged in an alternating manner according to the position of the vent holes. Exhaust pipe 604, two exhaust pipes 604 are respectively inserted into the outer wall of the corresponding heating sleeve 602.

[0026] When the heater for internal combustion engine vehicles is in use, the hot exhaust gas discharged from the combustion chamber 12 first flows through the exhaust pipe 14 and then through the diversion pipe 606 into the two filter chambers 605. The activated carbon rotating plates 612 inside the two filter chambers 605 rotate under the influence of the hot exhaust gas. During this process, the rotating activated carbon plates 612 continuously adsorb particles carried inside the hot exhaust gas, preventing blockage inside the subsequent heating sleeve 602 and improving heating efficiency. The filtered hot exhaust gas then flows through two air supply pipes 603 into the two heating sleeves 602, respectively, into the water outlet pipe 16 and the water inlet pipe 17 for heating. Because the two heating sleeves 602 are equipped with multiple flow-retardant baffles 610, the residence time of the hot exhaust gas inside the reheating sleeves 602 is increased, which greatly improves the heating efficiency. The temperature detector 601 installed on the outer wall of the water outlet pipe 16 detects the temperature of the water outlet pipe 16 in real time. Therefore, the adjustment rod 609 drives the adjustment plate 608 to rotate by adjusting the motor 607 according to the temperature of the water outlet pipe 16. This controls the flow rate of the hot exhaust gas by adjusting the size of the opening inside the exhaust pipe 14. Under this action, thermal compensation can be quickly performed when the water temperature at the water outlet pipe 16 is insufficient, ensuring that the liquid temperature always meets the requirements.

[0027] Reference Figures 1-3In a preferred embodiment, one end of a plurality of heat-conducting plates 13 is fixedly connected to the outer wall of the combustion chamber 12 at equal intervals, and the other end of the plurality of heat-conducting plates 13 is fixedly connected to the inner wall of the water heating chamber 11. The lower side of the connecting plate 7 is fixedly connected to the outer shell 1. The water heating chamber 11 is located inside the outer shell 1. A fuel supply pipe 2 is provided on the side of the fixed chamber 3 away from the gas outlet pipe 14. The oil outlet end of the fuel supply pipe 2 is inserted into the interior of the setting block 8. A fuel injector 10 is provided on the lower side of the setting block 8. The fuel injector 10 is connected to the fuel supply pipe 2. An igniter 9 is provided on the lower side of the setting block 8. Both the fuel injector 10 and the igniter 9 are located inside the combustion chamber 12. A gas collection chamber 4 is fixedly connected to the upper side of the fixed chamber 3. A gas-supporting pump 5 is provided on the upper side of the gas collection chamber 4. Two air inlet pipes 15 are provided at equal intervals on the lower side of the gas collection chamber 4. The outlet ends of the two air inlet pipes 15 pass through the outer wall of the fixed chamber 3 and the setting block 8 respectively and are located inside the combustion chamber 12.

[0028] When the heater for internal combustion engine vehicles is in use, fuel is supplied to the heater through the fuel supply pipe 2 and atomized inside the combustion chamber 12 by the fuel injector 10. Then, the atomized fuel inside the combustion chamber 12 is ignited by the igniter 9 to release a huge amount of heat. During this process, the combustion air is continuously supplied to the combustion chamber 12 through the combustion pump 5 and the two air intake pipes 15 to ensure that the atomized fuel can be fully burned.

[0029] Working Principle: When the internal combustion engine vehicle heater is in use, fuel is first supplied to the heater through the fuel supply pipe 2, and then atomized inside the combustion chamber 12 by the fuel injector 10. The atomized fuel inside the combustion chamber 12 is then ignited by the igniter 9, releasing a large amount of heat. During this process, the combustion air pump 5 continuously supplies combustion air into the combustion chamber 12 through two air intake pipes 15, ensuring complete combustion of the atomized fuel. The hot exhaust gas generated after combustion is discharged through the exhaust pipe 14, while the released heat is transferred to the water heating chamber 11 through multiple heat conduction plates 13. The cold liquid entering the water heating chamber 11 through the water inlet pipe 17 is heated to form hot liquid and then flows out through the water outlet pipe 16. Simultaneously, the hot exhaust gas discharged from the combustion chamber 12 first flows through the exhaust pipe 14 and then through the diversion pipe 606 into the two filter chambers 605. The activated carbon rotating plates 612 inside the two filter chambers 605 rotate under the blowing of the hot exhaust gas. During this process, the activated carbon... The rotation of the rotating plate 612 continuously adsorbs particles carried inside the hot exhaust gas, preventing blockage inside the subsequent heating sleeve 602 and improving heating efficiency. The filtered hot exhaust gas flows into the two heating sleeves 602 through two gas supply pipes 603, namely the water outlet pipe 16 and the water inlet pipe 17, for heating. At the same time, multiple flow-slowing baffles 610 are set inside the two heating sleeves 602 to increase the residence time of the hot exhaust gas inside the reheating sleeves 602, greatly improving heating efficiency. The temperature detector 601 set on the outer wall of the water outlet pipe 16 detects the temperature of the water outlet pipe 16 in real time. Based on the temperature of the water outlet pipe 16, the adjusting rod 609 drives the adjusting plate 608 to rotate by adjusting the motor 607, thereby adjusting the opening size inside the gas outlet pipe 14 to control the flow rate of the hot exhaust gas. Under this action, thermal compensation can be quickly performed when the water temperature at the water outlet pipe 16 is insufficient, ensuring that the liquid temperature always meets the requirements. Finally, the hot exhaust gas is discharged through the exhaust pipe 604.

[0030] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
