[0033] 2. Heat exchange mechanism and core channel principle The heat exchange channel 101 adopts an oblong cross-section design. When the medium flows through, it is decelerated due to the flow channel restriction, which prolongs the residence time and thus enhances the heat exchange effect.

[0034] 3. Connection relationship between solenoid valve 5 and equipment The front solenoid valve 5 on the left is connected to the gas outlet of the gas heating equipment; the front solenoid valve 5 on the right is connected to the gas inlet of the gas heating equipment through the front-end pipe; the rear solenoid valve 5 on the left is connected to the liquid outlet of the liquid heating equipment; the drain pipe 1004 is connected to the liquid inlet of the liquid heating equipment; the circulation pump 7 is used to drive the medium circulation of the longitudinal heat exchange channel 101.

[0035] Example 2: Multi-scenario heat exchange device adaptation solution (1) External heat exchange device of hot furnace Installation steps The interior of the heat exchanger 6 is pre-filled with a heat exchange medium and sealed with a direct heat exchange plate 8 , which is then fixed against the flat surface of the heat furnace.

[0036] Cycle Path The circulation pump 7 pushes the medium downward, enters the heat exchanger 6 through the check valve 11, passes through the lower heat exchange channel 101, the lower connecting bucket 2, the upper heat exchange channel 101, the upper connecting bucket 2 in sequence, and then flows back to the circulation pump 7 through the upper distribution and integration pipe 4 and the upper front solenoid valve 5.

[0037] (2) Internal heat exchange modification of equipment core components The extended heat exchange plate 9 is used to replace the straight heat exchange plate 8, the heat exchanger 6 and the deformed gooseneck tube 902 (memory metal material, can be manually shaped) are pre-filled with the medium, and the deformed gooseneck tube 902 is installed at a hole in the preset position of the equipment.

[0038] Circular Logic The medium is transported downward, enters the heat exchanger 6 through the check valve 11, and flows into the connecting module 901 and the deformed gooseneck 902 through the docking channel 903 to complete the cyclic heat exchange.

[0039] (3) Heat exchange mode of hot furnace exhaust gas Connect the heat exchanger 6 to the outside of the hot furnace, close the upper front electromagnetic valve 5, open the upper rear electromagnetic valve 5 and connect it to an external chimney or exhaust gas treatment equipment, and use the exhaust gas from the hot furnace for circulating heat exchange.

[0040] Example 3: Medium circulation mode and operating specifications (1) Pure gas medium circulation Only the left front solenoid valve 5 is opened, and the air in the gas heating equipment enters the horizontal heat exchange channel 101 through the left dividing and integrating pipe 4 and the left connecting bucket 2, and then flows back to the gas heating equipment through the right connecting bucket 2, the right dividing and integrating pipe 4 and the right front solenoid valve 5. The solenoid valve 5 that does not participate in the circulation remains closed.

[0041] (2) Pure liquid medium circulation Open the left rear solenoid valve 5. After the liquid is input, it circulates through the heat exchange channel 101 and flows into the water-gas integrated processor 10 from the right rear solenoid valve 5. Finally, it flows back to the liquid inlet end of the liquid heating equipment through the drain pipe 1004. If the liquid contains air, an air vent valve can be connected to the right front solenoid valve 5 to exhaust the air. The solenoid valve 5 that does not participate in the circulation remains closed.

[0042] (3) Gas-liquid dual synchronous heat exchange Open all solenoid valves 5 except the front solenoid valve 5 on the right side, input air and liquid media at the same time, and the gas and liquid enter the heat exchange core 1 synchronously for heat exchange, and then flow into the water-gas integrated processor 10 - the liquid is discharged from the drain pipe 1004, and the gas is discharged from the exhaust pipe 1001, realizing double heat exchange. The above situations can be matched with each other as needed.

[0043] Specific usage and function of this embodiment: In the present invention, first assemble the heat exchange core 1 and the connecting bucket 2, then install the outer plate 3 and other external accessories. The outer plate 3, the connecting multi-ribbed beam 302, and the side sealing plate 303 are fixed with sealant. The T-shaped pipe opening 201, the connecting pipe 301, and the pipe openings in other parts are fixed with butterfly pipe racks or similar tools. After assembly is completed, a vacuum pump is connected to the rear end of the one-way valve 304 to extract air, so that the interior of the four sets of peripheral plates 3 is in a vacuum state, reducing heat loss; conversely, the pull ring 308 can be pulled to inflate the air; since the heat exchange channel 101 is a long and flat channel, it will slow down the medium flowing through it, thus allowing the medium to flow in the heat exchange channel 101, thereby exchanging heat; When in use, the solenoid valves 5 on the left and right sides are assembled as inlet and outlet ends to connect the medium input and output sources; Connect the left front solenoid valve 5 to the gas outlet of the gas heating equipment; A pipe is provided at the front end of the right front solenoid valve 5 to connect to the air inlet end of the gas heating device; The outside of the left rear solenoid valve 5 is connected to the liquid outlet of the liquid heating device; The liquid discharge pipe 1004 is connected to the liquid inlet end of the liquid heating device; The circulation pump 7 is used to circulate the longitudinal heat exchange channel 101. If a heat exchange device needs to be installed outside the heat furnace of the equipment, the inside of the heat exchanger 6 can be pre-filled with medium, sealed with a straight heat exchange plate 8, and the straight heat exchange plate 8 is attached to the flat surface of the heat furnace and installed with bolts or other fixing methods; the circulation pump 7 provides a circulation effect, pushing the medium downward, passing through the check valve 11 into the heat exchanger 6, passing through the lower heat exchange channel 101 into the lower connecting bucket 2, passing through the heat exchange channel 101 and being discharged from the upper connecting bucket 2, passing through the upper distribution and integration pipe 4 and the upper front side solenoid valve 5 and returning to the circulation pump 7 to complete the circulation; If heat exchange is required inside the device, an expanded heat exchange plate 9 can be used instead of the straight heat exchange plate 8. The heat exchanger 6 and the deformed gooseneck tube 902 are also pre-filled with medium. The device is pre-opened and the deformed gooseneck tube 902 is installed inside the device. The deformed gooseneck tube 902 is made of memory metal and can be easily manually adjusted into a suitable shape and placed in a suitable position for continuous heat exchange. When the medium is transported downward, passes through the check valve 11 and enters the heat exchanger 6, it passes through the docking channel 903 and enters the connection module 901 and the deformed gooseneck tube 902 for circulation. In addition, you can also choose to use the hot air in the hot furnace for heat exchange, directly connect the heat exchanger 6 to the outside of the hot furnace, close the upper front solenoid valve 5, open the upper rear solenoid valve 5, and connect a chimney or exhaust gas treatment equipment outside the upper rear solenoid valve 5 to circulate; According to the different heat exchange media, you can choose as needed; When gas medium circulation is required, the left front solenoid valve 5 can be directly opened to allow the air in the gas heating device to flow into the left branching and integrating pipe 4 and the left connecting bucket 2, pass through the horizontal heat exchange channel 101, enter the right branching and integrating pipe 4 from the right connecting bucket 2, and flow back to the gas heating device through the right front solenoid valve 5 to circulate; during this period, the solenoid valve 5 not involved in the circulation is in the closed state; When liquid medium circulation is required, the left rear solenoid valve 5 is opened to input liquid for circulation heat exchange. The liquid medium flows through the right rear solenoid valve 5 into the water-gas integrated processor 10, and is finally discharged from the drain pipe 1004 and flows back to the liquid inlet end of the liquid heating device. In addition, if there is air in the liquid medium, the gas will be automatically discharged from the top. An air release valve can be installed outside the right front solenoid valve 5 to discharge the air. During this period, the solenoid valve 5 not participating in the circulation is in a closed state. If both devices need to be heated, all solenoid valves 5 can be opened and only the right front solenoid valve 5 can be closed. Air and liquid media can be input at the same time, and the gas and liquid can enter the heat exchange core 1 synchronously for heat exchange. Finally, both gas and liquid enter the water-gas integrated processor 10, and the liquid is discharged from the drain pipe 1004 and the gas is discharged from the exhaust pipe 1001, thus achieving dual synchronous heat exchange. Since liquid leakage is easily discovered by operators, but gas leakage is not easy to detect, if gas leakage occurs during the circulation, resulting in excess gas in the liquid circulation, the excess liquid will rise and the float valve 1003 will automatically close the exhaust; a liquid level sensor can be optionally set in the water-gas integrated processor 10 for monitoring; The above situations can be used as appropriate and matched with each other as needed to adopt different working combinations; if the inflow of the medium has no power, a pump body can be installed outside the two groups of solenoid valves 5 on the left as a power source to provide input power.
