Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a novel gas combustion heat exchanger which is convenient for disassembly and assembly. Background Technique

[0002] The gas combustion heat exchanger uses the heat generated by gas combustion to transfer the heat of the water pipe (or air passage) in the combustion chamber to the external water pipe (or air passage), so as to achieve the purpose of heating water and heating air. Specifically, gas burns in the combustion chamber, and the generated high-temperature flue gas passes through the inside of the heat exchanger and exchanges heat with the water or air passing through the heat exchanger, so that the temperature of the water or air rises, realizing the conversion and utilization of heat energy. The gas combustion heat exchanger is a device that uses the heat generated by gas combustion for heat exchange and is widely used in many fields such as industrial production, heating, ventilation and air conditioning, and domestic gas.

[0003] During the use of the existing gas combustion heat exchanger, it is not easy to repair, maintain or replace parts when a failure occurs. Moreover, when repairing or replacing parts at different positions or separately for the heat exchanger parts, the staff can only perform overall disassembly, resulting in a cumbersome disassembly process and also a cumbersome installation process, thus bringing trouble to the staff and reducing the use effect of the gas combustion heat exchanger. Content of the Utility Model

[0004] In view of the above defects or deficiencies in the prior art, the present application aims to provide a novel gas combustion heat exchanger that is convenient for disassembly and assembly, including a mounting plate.

Partition plates are provided at the left and right ends of the side of the heat exchange pipe. A slot is provided on the upper part of the mounting plate. A plug plate corresponding to the position of the slot is provided under the top plate. A thread groove engaged with a first threaded rod is provided above the top plate. The first threaded rod extends into the thread groove on the mounting plate through the thread groove in the top plate. A first bolt is sleeved outside the first threaded rod. A connecting rod is provided on the side of the mounting plate. The connecting rod extends through the mounting plate and the partition plate to the mounting plate and the partition plate on the other side. A second bolt is sleeved outside the connecting rod. A third bolt is provided on the side of the second bolt. A second threaded rod is provided inside the third bolt. The second threaded rod extends into the thread groove in the partition plate through the thread groove in the mounting plate.

[0005] Preferably, the top plate is installed above the mounting plate, and the air outlet pipe is connected to the middle of one side of the mounting plate.

[0006] Preferably, the heat exchange pipe is connected to the inner wall of the mounting plate, and the partition plates are symmetrically installed at the left and right ends of the side of the heat exchange pipe.

[0009] Preferably, the third bolt is threadedly connected to one side of the second bolt, and the second threaded rod is movably connected to the inner wall of the third bolt. Beneficial effects

[0010] When disassembling and assembling the heat exchanger assembly of this novel gas combustion heat exchanger that is easy to disassemble and assemble, the staff twists the first bolt outside the first threaded rod to remove the first bolt from the first threaded rod and disassembles them in sequence. After removing the first bolt and the first threaded rod above the top plate, the staff then moves the top plate upward to move the plug board out of the slot. At this time, the staff twists the second bolt to move the second bolt out of the connecting rod and disassembles them in sequence, so as to move the connecting rod out of the mounting plate and the partition plate. At the same time, by twisting the third bolt, the third bolt is moved out of the second threaded rod. At this time, there is looseness between the mounting plate and the partition plate, so it can be disassembled, enabling the staff to repair the internal components of the heat exchanger. At the same time, the whole heat exchange tube can be disassembled from the heat exchanger, which has the function of being easy to disassemble and install. And when repairing or replacing components at different positions of the heat exchanger, the staff can disassemble them separately, so that the heat exchanger can be easily disassembled when maintenance or component replacement is needed, improving the maintenance efficiency. At the same time, the installation process is simple and fast, reducing the installation time and cost. Description of the drawings
