[0026] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 7 , the utility model provides a technical solution:

[0028] like Figure 1-Figure 7 As shown, a condenser structure for a hot water unit includes a shell 12 and a baffle assembly and a water pipe 9 located in the shell 12. The shell 12 is a U-shaped structure. The shell 12 includes two cavities of the same specification. A water connection channel 11 and a smoke connection channel 10 are provided between the two cavities. A smoke outlet 8 and a water inlet 7 are provided at the lower end of one of the cavities, and a smoke inlet 6 and a water outlet 5 are provided at the lower end of the other cavity.

[0029] Each cavity is correspondingly provided with a baffle assembly, and the two baffle assemblies are symmetrically arranged. The baffle assemblies include a first baffle assembly 1, a second baffle assembly 2, a third baffle 3 and a fourth baffle 4. The second baffle assembly 2, the third baffle 3 and the fourth baffle 4 are all provided with a through hole 13 adapted to the outer diameter of the water pipe 9, and each of the through holes 13 is matched with a corresponding water pipe 9. The size of the third baffle 3 and the fourth baffle 4 is smaller than the inner size of the cavity, and the third baffle 3 and the fourth baffle 4 are staggered.

[0030] Through the above technical solution, the hot exhaust gas generated by the hot water unit enters the cavity through the smoke inlet 6 and flows between the baffle assemblies. At the same time, water enters the cavity on the other side from the water inlet 7 and flows along the water pipe 9. The second baffle assembly 2, the third baffle 3 and the fourth baffle 4 are all provided with a through hole 13 for the water pipe 9 to pass through. When the water pipe 9 is inserted into the through hole 13, the through hole 13 is filled, and the hot exhaust gas cannot flow through the through hole 13, and can only flow through the gaps between adjacent pipes and the staggered flow channels formed by the staggered third baffles 3 and the fourth baffles 4. The third baffle 3 and the fourth baffle 4 increase the residence time of the hot exhaust gas in the cavity. The hot exhaust gas fully exchanges heat with the water in the water pipe 9 through the flow channel formed after being blocked by the baffle assembly, and then enters the corresponding cavity on the other side from the smoke connecting channel 10 and the water connecting channel 11 respectively. Finally, the hot exhaust gas is discharged from the smoke outlet 8, and the water in the water pipe 9 enters the water bucket of the hot water unit from the water outlet 5 to replenish the water, thereby reducing the temperature of the hot exhaust gas and improving the heat utilization rate.

[0031] Furthermore, the through holes 13 of the overlapping areas of the second baffle assembly 2, the third baffle 3 and the fourth baffle 4 in the vertical direction are correspondingly located on the same axis.

[0032] Through the above technical solution, the same water pipe 9 can pass through the second baffle assembly 2, the third baffle 3 and the fourth baffle 4 in sequence, and form a channel for the circulation of hot exhaust gas through the gaps between multiple water pipes 9 and the staggered third baffles 3 and fourth baffles 4.

[0033] Furthermore, the water connecting channel 11 and the smoke connecting channel 10 are located at the top of the two cavities and respectively connect the two cavities, and the water connecting channel 11 is located above the smoke connecting channel 10 .

[0034] Furthermore, the size of the first baffle assembly 1 is adapted to the inner size of the cavity, and the first baffle assembly 1 includes an upper first baffle and a lower first baffle, the upper first baffle is fixed above the cavity and located on one side of the water connecting channel 11, and the lower first baffle is fixed at the bottom of the cavity.

[0035] Furthermore, the size of the second baffle assembly 2 is adapted to the inner size of the cavity, and the second baffle assembly 2 includes an upper second baffle and a lower second baffle, the upper second baffle is located below the upper first baffle and fixed on one side of the smoke connecting channel 10, and the lower second baffle is located above the lower first baffle.

[0036] Through the above technical solution, the first baffle assembly 1 seals the upper and lower ends of the cavity, and the water pipe 9 passes through the water connection channel 11. The water connection channel 11 forms a sealed space that can only be used for the water pipe 9 to pass through through the upper second baffle and the water pipe 9, thereby preventing hot exhaust gas from entering the water connection channel 11. The hot exhaust gas can only pass through the smoke connection channel 10.

[0037] Furthermore, the third baffle 3 and the fourth baffle 4 are located between the smoke connecting channel 10 and the lower second baffle.

[0038] Through the above technical solution, the third baffle 3 and the fourth baffle 4 are located between the smoke connecting channel 10 and the lower second baffle. Multiple baffles can be set as needed and arranged in a staggered manner to control the residence time of hot exhaust gas in the cavity to improve the heat exchange effect.

[0039] Furthermore, the water pipe 9 is a U-shaped pipe, and the middle portion of the water pipe 9 passes through the water connecting channel 11 .

[0040] Through the above technical solution, the water pipe 9 extends from the cavity on one side through the water connecting channel 11 into the cavity on the other side.

[0041] Furthermore, the water inlet 7 and the water outlet 5 are located between the lower second baffle and the lower first baffle, and the smoke inlet 6 and the smoke outlet 8 are located between the third baffle 3 and the lower second baffle.

[0042] Through the above technical solution, the water inlet 7 and the smoke outlet 8 are located in the same side cavity, and the water outlet 5 and the smoke inlet 6 are located in the same side cavity, so that the water flow direction and the hot exhaust gas flow direction are opposite, thereby improving the cooling and heat exchange effects of the smoke.

[0043] See also Figure 1 The hot exhaust gas generated by the burner in the hot water unit enters the cavity of the shell 12 through the smoke pipe from the smoke inlet 6. At the same time, external water enters the cavity of the shell 12 through the water inlet 7 and the water pipe 9.

[0044] Figure 1 The hollow arrow in the figure indicates the passage path of the hot flue gas in the shell 12. The space through which the hot flue gas passes is the space formed by the gap between the adjacent water pipes 9 and the inside of the cavity. Since the water pipes 9 are connected to the baffle assembly through the through holes 13, the hot flue gas flows through the area between the staggered third baffles 3 and the fourth baffles 4, and then enters the cavity on the other side from the flue gas connection channel 10. Since the baffle assemblies in the two cavities are symmetrical to each other, the hot flue gas continues to flow through the channel between the third baffle 3 and the fourth baffle 4. After the heat in the hot flue gas is fully heat-exchanged with the water in the water pipe 9 in the path, it is finally discharged from the smoke outlet 8, and the temperature of the hot flue gas is reduced while the heat conversion efficiency of the overall equipment is improved.

[0045] Figure 1 The solid arrow in the middle indicates the path of water in the shell 12. While the smoke route is running, the water at the water inlet 7 passes through the water pipe 9 and then through the water connecting channel 11 to reach the cavity on the other side of the shell 12. Since the baffle assemblies in the two cavities are symmetrically installed, the positions of the through holes 13 on the baffles are symmetrical, so the water pipes 9 are also symmetrically arranged in the two cavities. The water pipes 9 and the through holes 13 fit closely together to achieve a sealing effect, so the water eventually reaches the water outlet 5 and enters the water storage inside the hot water unit. During the path, the water in the water pipe 9 fully exchanges heat with the hot exhaust gas flowing in the opposite direction.

[0046] The utility model can improve the heat conversion efficiency, reduce the temperature of the exhaust hot gas, improve the safety of the working environment and equipment, and has a simple structure, is easy to install and has a low cost.

[0047] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be protected by the claims attached to the utility model.
