[0001] The present invention relates to the technical field of gas wall-mounted boilers, and particularly to a gas wall-mounted boiler device with a heat exchanger and its heat exchange method. Background Art

[0002] The full name of the "wall-mounted boiler" is: "gas wall-mounted heating furnace". It and the gas instantaneous water heater are both fast heating devices without a hot water storage device, but there are essential differences in structure. The gas wall-mounted boiler has a powerful central heating function for the family, can meet the heating needs of multiple rooms, and can also take into account the hot water bathing function. The heating function of the gas wall-mounted boiler is affected by two factors: local climate conditions and the insulation status of the building.

[0003] For example, in the patent named: A stainless steel coil for a wall-mounted boiler (patent application number: CN202120710036.4), a stainless steel coil for a wall-mounted boiler is disclosed. Through multiple heat exchange pipes, the temperature difference inside can reach the minimum value, ensuring consistent heat exchange effect, improving heat exchange quality, and having a simple structure and convenient use. However, when the liquid enters the inner coil at the bent pipe, due to the sudden change in flow direction, it will cause a large pressure on the bent pipe, and it is easy to be damaged after long-term use, reducing the service life of the stainless steel coil.

[0004] Therefore, it is very necessary to propose a gas wall-mounted boiler device with a heat exchanger and its heat exchange method to solve the above problems. Summary of the Invention

Detailed implementation manners

[0041] The present invention provides a gas wall-mounted boiler device with a heat exchanger as shown in Figures 1 to 10 . The gas wall-mounted boiler device with a heat exchanger includes a housing 1, a gas supply system, a combustion system, an exhaust system, etc. The heat exchanger body 2 is installed inside the housing 1. The gas wall-mounted boiler device and its working principle are both common existing technologies and will not be elaborated here.

[0042] Referring to Figure 3 , Figure 4 , Figure 5 , Figure 7 As shown, the heat exchanger body 2 includes an outer coil 3 and an inner coil 4. The inner coil 4 is distributed along the path of the outer coil 3 and is arranged inside the outer coil 3. A conveying channel 5 is formed between the inner wall of the outer coil 3 and the outer wall of the inner coil 4. The outer coil 3 includes an inlet end 8 and a pressure relief end 6. The conveying channel 5 communicates with the inner coil 4 at the pressure relief end 6. Most of the outer coil 3 and the inner coil 4 are arranged in a spiral shape to ensure the heat exchange area, and the other part is arranged vertically. The pressure relief end 6 corresponds to the vertical part. Among them, the pressure relief end 6 is located at a high position (refer to Figure 4 ), and the pressure relief end 6 may not be in direct contact with the flame of the combustion system, which is convenient for arranging a structure for pressure reduction.

[0043] Referring to Figure 5 As shown, a discharge pipe 7 is provided at the inlet end 8. The discharge pipe 7 penetrates the side wall of the outer coil 3 and communicates with the inner coil 4. An outlet end 9 is provided on the discharge pipe 7.

[0044] The outer coil 3, the inner coil 4, the discharge pipe 7, etc. are all made of heat-conducting materials, and stainless steel materials can be used but are not limited to, and can be adjusted according to specific usage situations.

[0045] During actual use, the inlet end 8 is docked with the water inlet end of the heat exchange system in the gas wall-mounted boiler device, and the outlet end 9 is connected to the water outlet end of the heat exchange system in the gas wall-mounted boiler device.

[0046] Furthermore, the liquid (water flow) enters the conveying channel 5 from the inlet end 8, and the liquid flows along the path of the conveying channel 5 to the pressure relief end 6, and heat exchange occurs with external heat (such as heat generated by the combustion system) during this process; then the liquid turns at the pressure relief end 6 and enters the inside of the inner coil 4. Since the inner coil 4 is arranged along the path of the outer coil 3, the liquid in the inner coil 4 and the liquid in the conveying channel 5 exchange heat again, with a better overall heat exchange effect, reducing the temperature difference during transportation and improving the heat exchange effect.

[0047] In addition, an installation fixing frame is provided on the heat exchanger body 2 for fixing the outer coil 3 and the inner coil 4 to ensure the stability of use.

[0048] Refer to Figure 6 、 Figure 7 、 Figure 8 As shown in Figure 7 , since the flow direction of the liquid changes at the pressure relief end 6, a relatively large impact pressure will be generated at this location. To achieve the effects of pressure reduction and guiding, and extend the service life of the heat exchanger body 2, a buffer block 11 is provided inside the pressure relief end 6. A diversion groove 12 is opened at the bottom end of the buffer block 11, and the central position at the bottom end of the buffer block 11 protrudes downward, so that the cross-section of the diversion groove 12 is in the shape of a ram's horn (refer to Figure 7 ), and the protruding position corresponds to the top end of the inner coil 4. At the same time, the outer diameter of the protruding position is significantly smaller than the inner diameter of the inner coil 4, which does not affect the liquid from entering the inside of the inner coil 4.

[0049] During actual use, the liquid flows along the path of the conveying channel 5 to the pressure relief end 6, and quickly enters the inside of the inner coil 4 under the guiding action of the diversion groove 12, playing a guiding role and ensuring the efficiency of liquid flow.

[0050] Refer to Figure 7 As shown in Figure 7 , a fixing plate 28 is integrally formed inside the pressure relief end 6. A through groove is opened on the fixing plate 28. A sliding column 13 is slidably arranged inside the through groove. A first spring 14 is sleeved outside the sliding column 13. The top end of the first spring 14 is fixedly connected to the bottom of the fixing plate 28, and the bottom end of the first spring 14 is fixedly connected to the bottom of the sliding column 13, and the buffer block 11 is rotatably arranged at the bottom end of the sliding column 13.

[0051] The buffer block 11 can be made of, but is not limited to, stainless steel. The first spring 14 can be made of, but is not limited to, high-temperature resistant materials, such as nickel-based superalloys, etc., which are suitable for high-temperature environments and can be adjusted according to specific usage conditions.

[0052] Specifically, the liquid flows upward through the conveying channel 5 and first acts on the buffer block 11, pushing the buffer block 11 to move upward. The first spring 14 contracts, playing a role in unloading force and buffering. Since the buffer block 11 has a certain thickness and under the guiding cooperation of the diversion groove 12, compared with the liquid directly impacting the pressure relief end 6, by setting structures such as the buffer block 11 and the diversion groove 12 in the present invention, the effects of reducing the impact pressure and guiding can be achieved, improving the heat exchange efficiency.

[0053] Refer to Figure 7 , Figure 9 , Figure 10 As shown in, a diversion bar 15 is installed on the diversion groove 12. The diversion bars 15 are inclinedly distributed, and there are multiple diversion bars 15, which are evenly distributed.

[0054] Since the buffer block 11 is rotatably arranged at the bottom end of the sliding column 13, when the liquid flows along the path of the conveying channel 5 to the pressure relief end 6, it will act on the diversion bar 15, causing the buffer block 11 to rotate and the liquid to generate a spiral motion.

[0055] First, generate a spiral motion to reduce the eddy current generated by the sudden change in flow velocity and flow direction of the liquid at the pressure relief end 6;

[0056] Second, generate a spiral motion to reduce the impact force and shear force of the liquid on the pressure relief end 6, thereby reducing the wear degree of the heat exchanger body 2 and extending the service life of the heat exchanger body 2;

[0057] Third, generate a spiral motion to achieve gas-liquid separation, separating the gas generated by heating in the liquid.

[0058] In summary, by setting the diversion bar 15 in cooperation with the diversion groove 12, the effects of reducing eddy current, reducing wear, and gas-liquid separation are achieved simultaneously, and the water flow is more stable.

[0059] To discharge the gas separated at the pressure relief end 6 and achieve the effect of pressure reduction, refer to Figure 7 As shown in, a gas channel 17 is opened on the buffer block 11, and the gas channel 17 penetrates the bottom end of the buffer block 11. The gas channel 17 corresponds to the protruding position. When the liquid flows along the path of the conveying channel 5 to the pressure relief end 6 and quickly enters the interior of the inner coil 4 under the guiding action of the diversion groove 12, and the pressure relief end 6 is located at a high position, the protruding position is cleverly set, making it difficult for the liquid to enter the interior of the gas channel 17, thus ensuring the treatment of the gas.

[0060] Refer to Figure 7As shown in the figure, a circular plate 10 is fixedly connected to the top end of the sliding column 13. The circular plate 10 is slidably arranged inside the pressure relief end 6. A high-temperature resistant sealing ring is arranged between the circular plate 10 and the inner wall of the pressure relief end 6 to ensure the sealing performance during the sliding process. A suction chamber 29 is formed between the circular plate 10 and the fixed plate 28; a sliding cap 20 is slidably arranged at the top end of the pressure relief end 6. A stacking chamber 19 is formed between the sliding cap 20 and the circular plate 10. A second spring 21 is fixedly connected to the top end of the pressure relief end 6, and the top of the second spring 21 is fixedly connected to the sliding cap 20. Since the sliding cap 20 is slidably arranged at the top end of the pressure relief end 6 and the second spring 21 is provided, the stacking chamber 19 can collect the accumulated gas.

[0061] The gas passage 17 extends to the inside of the sliding column 13. The suction chamber 29 cooperates with the gas passage 17 and the stacking chamber 19 by means of a connecting component.

[0062] Specifically, the connecting component includes a first air hole 22 and a first one-way valve 23. The first air hole 22 is opened on the circular plate 10, and the first one-way valve 23 is installed inside the first air hole 22. By setting the first one-way valve 23, the gas inside the suction chamber 29 can enter the inside of the stacking chamber 19 through the first air hole 22 without reverse flow.

[0063] The connecting component further includes a second air hole 24 and a second one-way valve 25. The second air hole 24 is opened on the side wall of the top of the sliding column 13. The gas passage 17 is communicated with the suction chamber 29 through the second air hole 24. The second one-way valve 25 is installed inside the second air hole 24. By setting the second one-way valve 25, the gas at the gas passage 17 can enter the inside of the suction chamber 29 through the second air hole 24 without reverse flow.

[0064] Refer to Figure 7 As shown in the figure, a first pressure valve 18 is installed at the bottom end of the gas passage 17, and the opening and closing threshold value of the first pressure valve 18 can be set according to the size of the heat exchanger body 2, the model of the gas wall-mounted boiler equipment, etc., and will not be elaborated here.

[0065] An exhaust pipe 26 is installed on the sliding cap 20. The exhaust pipe 26 is communicated with the stacking chamber 19. A second pressure valve 27 is installed on the exhaust pipe 26. Similarly, the opening and closing threshold value of the second pressure valve 27 can be set according to the size of the heat exchanger body 2, the model of the gas wall-mounted boiler equipment, etc.; and a processing pipe is arranged to be docked with the exhaust pipe 26, and the processing pipe extends to the outside of the gas wall-mounted boiler equipment, so that the gas can be directly discharged without affecting the normal use of the gas wall-mounted boiler equipment.

[0066] During actual use, the liquid flows upward through the conveying channel 5 and first acts on the buffer block 11, pushing the buffer block 11 to move upward by a certain distance. The first spring 14 contracts, playing a role in unloading force and buffering. As the liquid continues to be conveyed, the temperature rises and gas continues to be separated, causing the pressure inside the pressure relief end 6 to gradually increase. This continues to push the buffer block 11 upward. When the pressure exceeds the threshold of the first pressure valve 18, the first pressure valve 18 opens. Since the buffer block 11 moves upward, the suction chamber 29 gradually expands. With the cooperation of the connection component, the gas is sucked into the inside of the suction chamber 29, playing a role in reducing pressure. After the gas is discharged, the pressure inside the pressure relief end 6 decreases, and the first pressure valve 18 closes, reducing heat loss and improving the heat exchange efficiency. Moreover, under the elastic supporting force of the first spring 14, the buffer block 11 and the circular plate 10 move downward to reset, and the suction chamber 29 gradually shrinks. With the cooperation of the connection component, the gas inside the suction chamber 29 enters the inside of the accumulation chamber 19.

[0067] By arranging structures such as the buffer block 11, the diversion groove 12, the diversion strip 15, and the gas channel 17, the present invention uses the liquid flow as the power, and simultaneously achieves effects such as guiding, unloading force and buffering, gas separation, and exhaust pressure reduction, avoiding excessive pressure inside the heat exchanger body 2 and improving the heat exchange efficiency of the gas-fired wall-mounted boiler equipment.

[0068] The first pressure valve 18 is arranged in cooperation with the gas channel 17 to selectively discharge the gas (not continuously and directly discharge), reducing heat loss and improving the heat exchange efficiency.

[0069] Since the sliding cap 20 is slidably arranged at the top of the pressure relief end 6 and is cooperated with the second spring 21, the accumulation chamber 19 is an elastic space that can expand and change for accumulating gas. The pressure of the gas accumulated inside the accumulation chamber 19 will only cause the second pressure valve 27 to open after exceeding the threshold of the second pressure valve 27, and it is discharged through the exhaust pipe 26, reducing contact with the external environment and further reducing heat loss.

[0070] Refer to Figure 7 As shown in [reference], a pressure sensor 16 is installed at the pressure relief end 6. During actual use, the probe end of the pressure sensor 16 can be extended into the pipeline, while the sensor body is arranged outside the heat exchanger body 2 at a position not affected by the combustion system, and the wires and the like are heat-insulated. By arranging the pressure sensor 16 to monitor the pressure at the pressure relief end 6, if the pressure at the pressure relief end 6 exceeds the bearing capacity of the exhaust structures such as the gas channel 17 due to continuous high-intensity use or faults of the gas-fired wall-mounted boiler equipment, etc., and the pressure sensor 16 monitors that this pressure exceeds the set threshold, the gas-fired wall-mounted boiler equipment is controlled to suspend use through structures such as the controller, ensuring the safe use of the gas-fired wall-mounted boiler equipment.

[0071] A pressure sensor 16 is provided to assist the main body 2 of the auxiliary heat exchanger in emergency treatment, ensuring the safe use of the gas wall-mounted boiler equipment.

[0072] The present invention also discloses a heat exchange method for a gas wall-mounted boiler equipment with a heat exchanger, which is applied to the above-mentioned gas wall-mounted boiler equipment with a heat exchanger, and further includes the following operation steps:

[0073] S1. The liquid flows along the path of the conveying channel 5 and exchanges heat with external heat.

[0074] S2. The liquid generates a spiral motion at the pressure relief end 6 and discharges the gas.

[0075] S3. The liquid enters the interior of the inner coil 4 and exchanges heat again.

[0076] Working principle: The liquid (water flow) enters the conveying channel 5 from the inlet end 8, and the liquid flows along the path of the conveying channel 5 to the pressure relief end 6, and exchanges heat with external heat (such as the heat generated by the combustion system) during this process; then the liquid turns at the pressure relief end 6 and enters the interior of the inner coil 4. Since the inner coil 4 is arranged along the path of the outer coil 3, the liquid in the inner coil 4 and the liquid in the conveying channel 5 exchange heat again, resulting in a better overall heat exchange effect, reducing the temperature difference during the conveying process, and improving the heat exchange effect.
