The plate-fin heat exchanger is generally used as a key heat recovery heat exchanger. The heat of natural gas combustion heats the water through the plate-fin heat exchanger, and hot water will flow out from the water outlet continuously. After searching, a Chinese patent with the authorization announcement number CN219714108U discloses a natural gas plate-fin heat exchanger that is easy to disassemble, including a heat exchanger; the top and bottom ends of the heat exchanger are fixedly connected with a mounting plate, and the mounting plate is installed with a mounting assembly, and the mounting assembly includes a mounting plate, a first limit assembly The utility model relates to a component and a second limiting component, wherein a mounting hole is provided on the mounting plate, a mounting cylinder is fixedly connected to one side of the mounting plate, a movable rod is clamped in the mounting cylinder, a connecting rod is fixedly connected to the other end of the movable rod, a button is fixedly connected to the other end of the connecting rod, and a first return spring is sleeved on the circumferential surface of one side of the mounting cylinder of the connecting rod; through the structural design of the mounting component, the limiting state of the first limiting component and the limiting state of the second limiting component can be released, and the plate-fin heat exchanger can be quickly disassembled through the reverse action of the compressed first return spring, thereby simplifying the disassembly steps and making it more convenient for the staff to replace or repair.
