Description

Technical Field

[0001] This utility model relates to the field of exhaust pipe technology, and in particular to an exhaust pipe with condensate diversion. Background Technology

[0002] In building exhaust systems and other applications, exhaust ducts are widely used for gas transport. Since the exhaust gas from cooking chambers often contains water vapor, condensation can easily occur during the pipeline transport process, especially at locations with large temperature differences at the exhaust duct outlets. This causes liquid water to condense and accumulate on the inner wall of the pipe. If this condensate is not drained in time, it may flow back into the equipment, causing corrosion, electrical short circuits, or operational malfunctions.

[0003] Most common exhaust systems currently employ a single-channel design, lacking an effective condensate separation and discharge mechanism. The mixing of condensate and gas not only exacerbates corrosion of the duct's inner wall but also easily combines with particulate matter to form deposits, causing duct blockage and reducing ventilation efficiency. Therefore, there is an urgent need for an exhaust duct structure with condensate diversion capabilities to achieve gas-liquid separation and directional condensate discharge, thereby improving the stability and safety of system operation. Utility Model Content

[0004] In view of this, an embodiment of the present invention provides an exhaust duct with condensate diversion to solve the problem that water vapor mixing and flowing in the exhaust duct can easily cause equipment corrosion.

[0005] An embodiment of this utility model provides an exhaust duct with condensate diversion, comprising:

[0006] Air inlet duct and air outlet duct;

[0007] The splitter pipe has its two ends connected to the air inlet pipe and the air outlet pipe, respectively;

[0008] A condensing structure is provided on the inner walls of the upper and lower sides of the split pipe. The condensing structure includes multiple guide plates and multiple condensing plates. The multiple guide plates and multiple condensing plates are continuously arranged along the length of the split pipe, so that the inner cavity of the split pipe forms an S-shaped airflow channel.

[0009] A heat exchange chamber is provided at the upper part of the diversion pipe. The heat exchange chamber is provided with multiple heat exchange structures, and each heat exchange structure is connected to a corresponding condenser plate.

[0010] The heat exchange structure includes a core plate, at least two heat pipes, a fin assembly, and a fan. The core plate is inserted into the interior of the condenser plate, the two heat pipes are connected to the core plate and the fin assembly, and the fan is located on one side of the fin assembly.

[0011] And a water storage tank connected to the bottom wall of the diversion pipe, the water storage tank being detachably connected to the diversion pipe for collecting condensed water droplets.

[0012] Furthermore, the bottom wall of the diversion pipe is inclined downwards as a slope, and the side wall of the diversion pipe transitions to its inclined bottom wall at a slope, with both slopes facing the water storage tank.

[0013] Furthermore, the fin assembly includes multiple rectangular copper plates, and the two heat pipes pass through the multiple rectangular copper plates;

[0014] The fan is positioned on one side of the fin assembly, facing the gap between the plurality of rectangular copper plates.

[0015] Furthermore, a drain pipe is connected to the bottom wall of the diversion pipe, and the drain pipe is detachably connected to the water storage tank.

[0016] Furthermore, a circular ring plate is connected to the open end of the drain pipe, and two folded edges are provided on the upper part of the water storage tank;

[0017] Both of the aforementioned folded edges are L-shaped, and the gap between each folded edge and the upper surface of the water storage tank corresponds to the width of the annular plate. The water storage tank slides with the annular plate through the two folded edges, allowing the water storage tank to slide apart from the drain pipe.

[0018] Furthermore, the top of the water storage tank is provided with a collection port, the diameter of which is smaller than the inner diameter of the drain pipe.

[0021] Furthermore, the air outlet pipe and the air inlet pipe are on the same axis at their connecting ports at both ends of the split pipe.

[0022] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows: The exhaust duct with condensation diversion of this utility model sets a diversion pipe between the air inlet pipe and the air outlet pipe, and arranges guide plates and condensing plates alternately and continuously in the diversion pipe to form an S-shaped airflow channel. This allows the humid gas to change its flow direction multiple times during the flow process and fully contact the condensing plate, thereby significantly improving the water vapor condensation efficiency. The condensate quickly flows into the water storage tank along the inclined bottom wall under the action of gravity, realizing efficient dehumidification and water recovery. At the same time, by connecting the heat exchange structure to the condensing plate, the efficient heat dissipation system composed of core plate, heat pipe, fin group and fan is used to quickly remove the condensation heat, keep the condensing plate at a low temperature, further improve the condensation effect and reduce energy consumption. In addition, the water storage tank and the drain pipe are connected by a sliding and detachable connection, which is convenient for cleaning and maintenance. The guide plate has a drain port and is slidably connected to the bottom wall of the diversion pipe, which is conducive to the rapid discharge of condensate and structural cleaning. The overall structure is compact, stable in operation and convenient in maintenance. It can be widely used in occasions that require dehumidification and exhaust, and has good energy-saving and environmental protection benefits. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings. The following description presents a preferred embodiment of several possible embodiments of this utility model, intended to provide a basic understanding of the utility model, but not intended to identify the key or decisive elements of the utility model or to limit the scope of protection sought.

Also, it should be understood that, for ease of description, the dimensions of the various parts shown in the figures are not drawn to actual scale.

[0033] In the description of this utility model, it should be noted that the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0034] It should be further noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] Please refer to Figure 1 An embodiment of this utility model provides an exhaust duct with condensation diversion, including an air inlet pipe 1, a diversion pipe 2, an air outlet pipe 3, a condensation structure, and a water storage tank 9.

[0036] The air inlet pipe 1 and the air outlet pipe 3 are connected by a split pipe 2. The connection ports of the air inlet pipe 1 and the air outlet pipe 3 at both ends of the split pipe 2 are located on the same axis to ensure smooth airflow and reduce turbulence loss.

[0037] Please refer to Figure 1 and Figure 2 The condensation structure is set on the inner walls of the upper and lower sides of the split pipe 2, including multiple guide plates 4 and multiple condensation plates 5. The guide plates 4 and condensation plates 5 are arranged alternately and continuously along the length of the split pipe 2, so that the inner cavity of the split pipe 2 forms an S-shaped airflow channel.

[0038] As the gas flows through the S-shaped channel, it changes direction multiple times and comes into full contact with the condenser plate 5. Water vapor condenses into water droplets on the surface of the condenser plate 5, thus achieving condensation and diversion.

[0039] It should be noted that the bottom wall of the diversion pipe 2 is inclined downwards, and the bottom wall has two inclined surfaces, both of which face the water storage tank 9.

[0040] This design allows condensate to flow quickly into the water storage tank 9 under the influence of gravity, preventing water accumulation.

[0041] In another optional embodiment, a heat exchange chamber 6 is provided at the upper part of the diversion pipe 2. The heat exchange chamber 6 is provided with a plurality of heat exchange structures 7, each heat exchange structure 7 being connected to a corresponding condenser plate 5. The heat exchange structure 7 includes a core plate 10, at least two heat pipes 11, a fin assembly 12, and a fan 13.

[0042] It should be noted that the core plate 10 is inserted into the interior of the condenser plate 5 and can be fixed by using thermal grease or welding to improve the heat conduction efficiency. One end of the heat pipe 11 is connected to the core plate 10, and the other end is inserted into the fin assembly 12.

[0043] Furthermore, the fin assembly 12 is composed of multiple rectangular copper plates, and two heat pipes 11 pass through the multiple rectangular copper plates; the fan 13 is located on one side of the fin assembly 12, and its air outlet faces the gap between the rectangular copper plates to accelerate airflow, remove heat, and improve condensation efficiency.

[0044] Based on the above embodiments, the heat exchange chamber 6 can be connected to an external refrigeration cycle loop to further reduce the temperature of the condenser plate 5 and improve the dehumidification efficiency. The rest of the structure is the same as in Embodiment 1, and will not be described again here.

[0045] Please refer to Figures 4 to 5 The bottom wall of the diversion pipe 2 is connected to the drain pipe 8, and the drain pipe 8 is detachably connected to the water storage tank 9.

[0046] Specifically, the opening end of the drain pipe 8 is connected to the outer ring plate 14, and the upper part of the water storage tank 9 is provided with two folded edges 15, both of which are L-shaped. Each folded edge 15 forms a slot with the upper surface of the water storage tank 9, and the width of the slot matches the thickness of the ring plate 14.

[0047] During installation, push the water tank 9 horizontally to allow the ring plate 14 to slide into the slot for quick installation; during disassembly, slide it in the opposite direction to separate.

[0048] In addition, a collection port 16 is provided on the top of the water storage tank 9. The diameter of the collection port 16 is smaller than the inner diameter of the drain pipe 8 to prevent condensate from splashing out.

[0049] The guide plate 4 is connected to the bottom wall of the diversion pipe 2 and has multiple drain ports 401. The drain ports 401 prevent condensate from accumulating on the guide plate 4.

[0050] In another optional embodiment, in order to facilitate changing the gap between the guide plate 4 and the multiple condenser plates 5 and change the gas flow rate, the multiple guide plates 4 are connected by a connecting plate 17, and the guide plates 4 can be slidably connected relative to the bottom wall of the diversion pipe 2.

[0051] For example, the bottom wall of the splitter 2 is provided with a groove, and the bottom of the guide plate 4 is provided with a slider. The slider and the groove cooperate to achieve a sliding connection. When multiple guide plates 4 are slidably adjusted to one side, the adjacent gap between the guide plate 4 and the condenser plate 5 is reduced, so the gas flow speed is faster, so as to adapt to different working conditions.

[0052] The working process of this embodiment is as follows:

[0053] Gas containing water vapor enters the split pipe 2 through the air inlet pipe 1. It comes into contact with the condenser plate 5 multiple times in the S-shaped airflow channel inside the split pipe 2. The water vapor condenses into water droplets upon contact with the cooler condenser plate 5. The water droplets flow downward along the condenser plate 5 and fall between the guide plate 4 and the inner wall of the split pipe 2. They then flow into the water storage tank 9 through the drain outlet 401 and the drain pipe 8. The condensed dry gas is discharged through the air outlet pipe 3. The heat absorbed by the condenser plate 5 is transferred to the fin assembly 12 through the core plate 10 and the heat pipe 11. The fan 13 provides forced convection cooling, keeping the condenser plate 5 at a low temperature and enabling continuous and efficient condensation.

[0054] In this document, the directional terms such as front, back, top, and bottom are defined based on the position of the components in the accompanying drawings and their relative positions to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.

[0055] Where there is no conflict, the above embodiments and features described herein can be combined with each other.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
