The defects of this method are that it is troublesome to position the two sides of the water box, and the efficiency is too low; and the surface welding of the water box or its welding surface is uneven, and the welding traces affect the appearance, so in order to deal with the above problems, a solution to the problem is proposed;

[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0024] A heat exchanger water box connection structure includes an upper box cover 1, an upper box top plate 2, a lower box top plate 4 and a lower box cover 5. The upper box top plate 2 and the lower box top plate 4 are both provided with annular grooves. The upper box cover 1 is installed in the annular groove of the upper box top plate 2, and the lower box cover 5 is installed in the annular groove of the lower box top plate 4. Foldable rivet nails 10 are installed at the edges of the two annular grooves. The rivet nails 10 in the upper box top plate 2 are folded to abut the upper box cover 1 in the annular groove of the upper box top plate 2, and the rivet nails 10 in the lower box top plate 4 are folded to abut the lower box cover 5 in the annular groove of the lower box top plate 4.

[0025] Among them, an annular groove for accommodating the upper box cover 1 is selected to be opened on the upper box top plate 2, and the upper box cover 1 is subsequently installed in the annular groove, and the bottom surface of the upper box cover 1 contacts the bottom of the annular groove, and a rivet nail 10 is arranged at the edge of the annular groove, and the rivet nail 10 is subsequently turned inward (folded at the center) so that the rivet nail 10 abuts the upper box cover 1 against the bottom and side walls of the annular groove in the upper box top plate 2;

[0026] Similarly, an annular groove for accommodating the lower box cover 5 is also selected to be opened on the lower box top plate 4. The lower box cover 5 is subsequently installed in the annular groove, and the bottom surface of the lower box cover 5 contacts the bottom of the annular groove. Riveting nails 10 are also placed at the edge of the annular groove. The rivet nails 10 are subsequently turned inward (folded at the center) so that the rivet nails 10 can abut the upper box cover 1 against the bottom and side walls of the annular groove in the upper box top plate 2.

[0027] The number of riveting nails 10 is set to six and is evenly distributed along the edge of the annular groove, so that folding and fastening operations can be performed at multiple locations.

[0028] Furthermore, in order to connect the upper and lower chambers, multiple guide tubes 3 are designed as guide rows, and multiple guide tubes 3 are connected between the upper box top plate 2 and the lower box top plate 4. The top of each guide tube 3 is seamlessly connected to the upper box top plate 2, and the bottom of each guide tube 3 is seamlessly connected to the lower box top plate 4. The specific seamless connection is: mounting holes for accommodating the guide tubes 3 are opened on the upper box top plate 2 and the lower box top plate 4, one end of the guide tube 3 is interference fit with the mounting hole of the upper box top plate 2, and the other end of the guide tube 3 is interference fit with the mounting hole of the lower box top plate 4.

[0029] A first water inlet pipe 8 is installed on the upper box cover 1 , and a first drain pipe 6 is installed on the lower box cover 5 .

[0030] A second water inlet pipe 9 is installed on the upper box cover 1 , and a second drain pipe 7 is installed on the lower box cover 5 . An inner tube is inserted into the flow guide tube 3 , and the water inlet end of the inner tube is connected to the second water inlet pipe 9 , and the drain end of the inner tube is connected to the second drain pipe 7 .

[0031] Solder paste is selectively applied in two annular grooves, and the solder paste is applied on the surfaces of the contact parts between the upper box cover 1 and the upper box top plate 2, and the lower box cover 5 and the lower box top plate 4, respectively. The solder paste brings the two connected parts together to form permanently connected solder joints after cooling, so as to enhance the connectivity between the two.

[0032] Baffles 11 are installed at both the upper and lower ends of the guide pipe 3, and a plurality of heat absorbing plates 12 are arranged between the two baffles 11. The heat released by the fuel of the subsequent combustion equipment is absorbed by the heat absorbing plates and conducted to the two pipelines inside the device, thereby realizing dual-channel heating. It is worth noting that the liquid temperature in the outer circulation pipeline is higher than the liquid temperature in the inner circulation pipeline, which can meet the synchronous heating requirements.

[0033] During normal use, the two water inlet pipes and the two drainage pipes are connected to the external pipes respectively, wherein the liquid to be heated enters the internal cavity of the upper box cover 2 through the first water inlet pipe 8, and then enters the internal cavity of the lower box cover 5 through the flow guide pipe 3 interconnected therewith, and is finally discharged through the first drainage pipe 6, which is the first heating pipeline; at the same time, the liquid to be heated enters the internal circulation pipeline inside the device through the second water inlet pipe 9, and is discharged through the second drainage pipe, which is the first heating pipeline; and the internal circulation pipeline in the second heating pipeline is immersed in the liquid in the first heating pipeline, and the heat energy of the external combustion equipment is conducted to the heat absorption plate 12, and the heat absorption plate 12 is conducted to the flow guide pipe 3, and after the liquid in the flow guide pipe 3 is heated, the heat energy is conducted to the internal circulation, so that the liquid in the internal circulation pipeline is heated.
