Description

Technical Field

[0001] This utility model belongs to the technical field of condensing dual-channel heat exchangers, and specifically relates to a condensing dual-channel heat exchanger. Background Technology

[0002] The condensing dual-channel heat exchanger is a highly efficient and energy-saving heat exchange device. Its core design optimizes heat exchange efficiency through a dual-channel structure, making it particularly suitable for industrial scenarios requiring simultaneous processing of gas and liquid phases or heat recovery. Through structural innovation and thermodynamic optimization, the condensing dual-channel heat exchanger offers significant advantages in improving energy efficiency and reducing emissions. Its design requires comprehensive consideration of operating conditions, material selection, and flow field control. With future advancements in intelligent manufacturing and materials science, it is expected to provide efficient and low-carbon thermal management solutions in more fields. High-temperature gases (such as flue gas and steam) and low-temperature cooling media (such as water and air) flow counter-currently within the dual channels, transferring heat through the pipe walls or plates. As the high-temperature gas temperature decreases, some water vapor condenses into liquid, releasing latent heat. The condensate is collected and discharged through a water collection device, preventing secondary evaporation and heat loss. Some devices also incorporate diversion plates or insulation plates to prevent the condensate from evaporating again.

[0003] Currently, existing condensing dual-channel heat exchangers typically achieve heat exchange through heat dissipation pipes and heat collection fins. However, traditional condensing dual-channel heat exchangers often lack a dustproof structure, so after prolonged use, a large amount of dust easily accumulates on the surface of the heat collection fins. If this dust is not cleaned in time, it may affect the heat exchange effect, thereby reducing the working efficiency of the condensing dual-channel heat exchanger. Utility Model Content

[0004] The purpose of this invention is to provide a condensing dual-channel heat exchanger, which aims to solve the problem that existing condensing dual-channel heat exchangers typically achieve heat exchange through heat dissipation pipes and heat collection fins. However, traditional condensing dual-channel heat exchangers often lack a dustproof structure, so after prolonged use, a large amount of dust easily accumulates on the surface of the heat collection fins. If this dust is not cleaned in time, it may affect the heat exchange effect and reduce the working efficiency of the condensing dual-channel heat exchanger.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a condensing dual-channel heat exchanger, comprising two water tanks, a connecting frame fixedly connected between the two water tanks, a plurality of heat dissipation pipes connected between the water tanks, and heat collection plates connected to the outer walls of the plurality of heat dissipation pipes;

[0006] The outer walls of the two water tanks are respectively connected to a connecting pipe. A dustproof plate is installed on the inner side of the connecting frame. Grooves are opened on both sides of the dustproof plate. A limit slot is opened on the inner side of the groove. An installation seat is fixedly connected to the inner wall of the connecting frame. A spring is movably connected inside the installation seat. A movable block is connected to the end of the spring. A limit pin is fixedly connected to one end of the movable block.

[0007] In a preferred embodiment of this utility model of a condensing dual-channel heat exchanger, the mounting base is located inside the groove.

[0008] In a preferred embodiment of this utility model of a condensing dual-channel heat exchanger, the end of the limiting pin furthest from the movable block is adapted to the size of the limiting slot.

[0009] As a preferred embodiment of the condensing dual-channel heat exchanger of this utility model, the connecting frame can form an elastic locking structure with the dustproof plate through grooves, limiting slots, mounting bases, springs, movable blocks, and limiting pins.

[0010] In a preferred embodiment of this utility model of a condensing dual-channel heat exchanger, an L-shaped insert is fixedly connected to the outer wall of the dustproof plate, positioning grooves are provided at the top and bottom of the connecting frame, fixing blocks are fixedly connected to the top and bottom of the connecting frame, and positioning slots are provided at the ends of the fixing blocks.

[0012] In a preferred embodiment of this utility model of a condensing dual-channel heat exchanger, the end of the L-shaped insert away from the dustproof plate is adapted to the size of the positioning slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By moving the movable block with the lever, the limiting pin is retracted, and then the dustproof plate is embedded inside the connecting frame. At this time, the mounting base will be located inside the groove on the outer wall of the dustproof plate. Then, by releasing the lever, the limiting pin will pop out under the action of the spring and be inserted into the limiting slot inside the groove, thereby realizing the installation and fixation of the dustproof plate. The dustproof plate can then play a dustproof role and prevent dust from adhering to the surface of the heat collection plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 The present invention provides the following technical solution: a condensing dual-channel heat exchanger, comprising two water tanks 1, a connecting frame 2 fixedly connected between the two water tanks 1, multiple heat dissipation pipes 3 connected between the water tanks 1, and heat collection plates 4 connected to the outer walls of the multiple heat dissipation pipes 3.

[0025] Two water tanks 1 are connected to a connecting pipe 5 on their outer walls respectively. A dustproof plate 6 is installed on the inner side of the connecting frame 2. Grooves 7 are opened on both sides of the dustproof plate 6. A limit slot 8 is opened on the inner side of the groove 7. An installation seat 9 is fixedly connected to the inner wall of the connecting frame 2. A spring 10 is movably connected inside the installation seat 9. A movable block 11 is connected to the end of the spring 10. A limit pin 12 is fixedly connected to one end of the movable block 11.

[0026] It should be noted that spring 10 is made of stainless steel, which has good corrosion resistance and can resist the erosion of various chemicals. Among them, 304 stainless steel springs have good corrosion resistance in general atmospheric environments and weakly corrosive media; 316 stainless steel springs contain molybdenum, which has stronger resistance to chloride ions and other substances, and is suitable for harsher corrosive environments. Both types can be used according to the actual situation.

[0027] Preferably, the mounting base 9 is located inside the groove 7, and the end of the limiting pin 12 away from the movable block 11 is adapted to the size of the limiting slot 8. The connecting frame 2 can form an elastic locking structure with the dustproof plate 6 through the groove 7, the limiting slot 8, the mounting base 9, the spring 10, the movable block 11, and the limiting pin 12.

[0028] In practical use, the movable block 11 is moved by the lever to retract the limiting pin 12, and then the dustproof plate 6 is embedded into the inner side of the connecting frame 2. At this time, the mounting base 9 will be located inside the groove 7 on the outer wall of the dustproof plate 6. Then, by releasing the lever to move the limiting pin 12, it will pop out under the action of the spring 10 and insert into the limiting slot 8 inside the groove 7, thereby realizing the installation and fixation of the dustproof plate 6. Then, the dustproof plate 6 can play a dustproof role and prevent dust from adhering to the surface of the heat collection plate 4.

[0029] Conversely, during disassembly, the movable block 11 is moved by the lever to retract the limit pin 12. At this time, the limit pin 12 will disengage from the inside of the limit slot 8. Then, by pulling the dustproof plate 6 outward, the dustproof plate 6 can be removed from the inside of the connecting frame 2, thereby making it easy to disassemble the dustproof plate 6 and facilitate subsequent cleaning.

[0030] Preferably, an L-shaped insert 13 is fixedly connected to the outer wall of the dustproof plate 6, and positioning grooves 14 are provided at the top and bottom of the connecting frame 2. A fixing block 15 is fixedly connected to the top and bottom of the connecting frame 2, and a positioning slot 16 is provided at the end of the fixing block 15. One end of the L-shaped insert 13 is located inside the positioning groove 14, and the end of the L-shaped insert 13 away from the dustproof plate 6 is adapted to the size of the positioning slot 16.

[0031] In practical use, with the L-shaped insert 13, positioning groove 14, fixing block 15 and positioning slot 16, when the dustproof plate 6 is installed inside the connecting frame 2, one end of the L-shaped insert 13 will be embedded in the positioning groove 14, and the other end of the L-shaped insert 13 will be inserted through into the positioning slot 16 at the end of the fixing block 15, thereby playing a positioning role and improving the stability of the dustproof plate 6 after installation.

[0032] Working principle: First, a condensing dual-channel heat exchanger is assembled from the water tank 1, connecting frame 2, heat dissipation pipe 3, heat collection plate 4, and connecting pipe 5. Then, by moving the movable block 11 with a lever, the limiting pin 12 retracts, and the dustproof plate 6 is embedded into the inner side of the connecting frame 2. At this time, the mounting base 9 will be located inside the groove 7 on the outer wall of the dustproof plate 6. Then, by releasing the lever, the limiting pin 12 will pop out under the action of the spring 10 and insert into the limiting slot 8 inside the groove 7, thereby realizing the installation and fixation of the dustproof plate 6. The dustproof plate 6 can then play a dustproof role, preventing dust from adhering to the surface of the heat collection plate 4. And through the L-shaped insert 13 and positioning groove 14 The fixing block 15 and positioning slot 16 are designed so that when the dustproof plate 6 is installed inside the connecting frame 2, one end of the L-shaped insert 13 will be embedded in the positioning groove 14, and the other end of the L-shaped insert 13 will be inserted through the positioning slot 16 at the end of the fixing block 15, thereby playing a positioning role and improving the stability of the dustproof plate 6 after installation. Finally, during disassembly, the movable block 11 is moved by the lever to drive the limit pin 12 to retract. At this time, the limit pin 12 will disengage from the inside of the limit groove 8. Then, by pulling the dustproof plate 6 outward, the dustproof plate 6 can be taken out from the inside of the connecting frame 2, thereby enabling the dustproof plate 6 to be easily disassembled and facilitating subsequent cleaning.

[0033] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
