Description

Technical Field

[0001] This utility model belongs to the field of heat exchange structure technology, and more specifically, it relates to a heat exchange structure for a gas-fired heating hot water boiler. Background Technology

[0002] In the field of gas-fired heating and hot water boilers, heat exchange structures are often used to transfer heat energy generated by gas combustion to cold water to meet users' heating and domestic hot water needs. In daily household use, gas-fired heating and hot water boilers are often equipped with dedicated heat exchange structures to achieve efficient, stable heating and a sufficient supply of hot water. However, traditional devices lack the ability to alter fluid turbulence. As a result, during the heat exchange process, the fluid is in a relatively stable flow state, which prevents it from fully contacting the heat transfer surface and exchanging heat effectively. This leads to low heat transfer efficiency, causing the gas to burn for extended periods to maintain the hot water supply. This not only results in significant energy waste but also shortens the lifespan of the gas equipment. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a heat exchange structure for a gas-fired heating and hot water boiler, thereby solving the technical problem that traditional devices in the prior art do not have the function of changing fluid disturbance.

[0004] The purpose and effect of the heat exchange structure for a gas-fired heating hot water boiler of this utility model are achieved by the following specific technical means:

[0005] A heat exchange structure for a gas-fired heating hot water boiler includes a packaging shell with receiving cavities on both sides. A composite layer is provided inside the packaging shell, and a pressurized water tank is located within the composite layer. A heat exchange mechanism is provided within the pressurized water tank. The heat exchange mechanism includes two sets of sealing head plates, which are respectively located on the inner walls of both sides of the pressurized water tank. The two sets of sealing head plates are connected by multiple sets of connecting columns. Multiple sets of clamping blocks are fitted onto the connecting columns, and each set of clamping blocks has a partition wall heat exchange plate. Multiple sets of perforations are provided on both the partition wall heat exchange plates and the two sets of sealing head plates. Multiple sets of flow ripples are provided on the partition wall heat exchange plates.

[0006] According to a preferred embodiment, the pressurized water tank is provided with multiple sets of cold water flow pipes, which pass through multiple sets of partition heat exchange plates and are installed on two sets of sealing head plates. Each end of the multiple sets of cold water flow pipes is provided with a liquid flow cover.

[0007] According to a preferred embodiment, multiple sets of through holes are provided on the multiple sets of liquid flow covers, and each of the multiple sets of cold water flow pipes is provided with a turbulence column, with both ends of the multiple sets of turbulence columns connected to the multiple sets of liquid flow covers.

[0008] According to a preferred embodiment, the composite layer includes an insulation layer and a reinforcing frame, the reinforcing frame being located on the outer wall of the insulation layer, the insulation layer being bonded to the pressurized water tank, and the insulation layer being made of glass wool.

[0009] According to a preferred embodiment, the packaging shell is provided with caps on both sides, and multiple sets of perforations are provided on the multiple sets of caps, with both ends of the multiple sets of cold water pipes passing through the multiple sets of caps.

[0010] According to a preferred embodiment, each of the multiple sets of caps is fitted with a sealing ring, one end of each sealing ring is attached to the packaging shell, and multiple sets of connection holes are provided on the packaging shell, the composite layer and the pressurized water tank, and each set of connection holes is provided with a hot water inlet / outlet pipe.

[0011] According to a preferred embodiment, filter plates are fitted onto multiple sets of the receiving cavity shells, cold water inlet and outlet pipes are provided on multiple sets of the receiving cavity shells, and foot covers are fitted onto the packaging shell.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This device enhances fluid turbulence during heat exchange by using corrugated flow lines on the heat exchange plate and turbulence columns inside the cold water pipe. This improves the device's heat exchange efficiency. After the heat generated by gas combustion is transferred to the pressurized water tank, the user can change the water flow path through the corrugated flow lines on the heat exchange plate to increase the contact area and time between the water and the heat exchange plate. This allows the user to obtain hot water more quickly and improves the device's capabilities in heat transfer and hot water supply.

[0014] 2. When using this device, users can reduce heat loss by using glass wool as the insulation layer in the composite layer inside the packaging shell, thereby reducing energy consumption and improving the device's insulation performance. Furthermore, the filter plate installed on the housing shell allows the device to filter incoming cold water, reducing the impact of impurities on the heat exchange structure and improving the device's ability to operate stably over long periods.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0022] Example:

[0023] like Figures 1 to 4 As shown, this utility model provides a heat exchange structure for a gas-fired heating and hot water boiler. The packaging shell 11 serves as an external enclosure, providing protection and a base for the internal components. The receiving chamber shells 12 on both sides increase the space utilization of the overall structure. The filter plate 27 installed on the receiving chamber shell 12 can perform preliminary filtration of the cold water entering from the cold water inlet / outlet pipe 28, removing impurities and ensuring the quality of the cold water entering the pressurized water tank 13, thereby ensuring the normal operation of the internal heat exchange components. Through the cooperation of the receiving chamber shell 12, the filter plate 27 and the cold water inlet / outlet pipe 28, the device has the ability to perform preliminary purification of cold water, improving the purity of the cold water entering the heat exchange system and laying the foundation for subsequent stable heat exchange.

[0024] The composite layer inside the packaging shell 11 consists of an insulation layer 22 and a reinforcing frame 23. The insulation layer 22 is made of glass wool and is attached to the pressurized water tank 13. Its main function is to reduce heat loss within the pressurized water tank 13, reduce energy consumption, and improve the energy efficiency of the device. The reinforcing frame 23 is located on the outer wall of the insulation layer 22, enhancing the overall structural strength of the composite layer and providing support for the pressurized water tank 13. Through the coordinated arrangement of the reinforcing frame 23 and the insulation layer 22, the composite layer possesses both excellent thermal insulation performance and reliable structural stability, ensuring the safe and stable operation of the pressurized water tank 13.

[0025] The heat exchange mechanism installed inside the pressurized water tank 13 is the core component for achieving heat exchange. Two sets of sealing head plates 14 are located on the inner walls of both sides of the pressurized water tank 13 and are interconnected by multiple sets of connecting columns 15. The sealing head plates 14 not only seal both ends of the pressurized water tank 13 but also provide fixed support for other heat exchange components. The connecting columns 15 connect the sealing head plates 14 on both sides, ensuring the integrity of the overall structure of the heat exchange mechanism. The arrangement of the sealing head plates 14 and connecting columns 15 ensures the stability of the heat exchange mechanism within the pressurized water tank 13, guaranteeing smooth heat exchange under pressure. Multiple sets of clamping blocks 16 fitted onto the multiple sets of connecting columns 15 each hold a partition heat exchange plate 17. Multiple sets of flow corrugations on the partition heat exchange plate 17 and multiple sets of perforations on the two sets of sealing head plates 14 enhance heat exchange.

[0026] The ripples alter the flow path of the fluid on the surface of the partition heat exchange plate 17, enhancing fluid turbulence and improving heat exchange efficiency; the perforations are used for the passage of the cold water flow pipe 18, enabling connection and fluid flow between components. Through the arrangement of the clamping block 16, the partition heat exchange plate 17, the ripples, and the perforations, the device enhances fluid turbulence, optimizes heat exchange efficiency, and simultaneously achieves a reasonable layout and connection of components, ensuring the operation of the heat exchange system. Multiple sets of cold water flow pipes 18 within the pressurized water tank 13 pass through multiple sets of partition heat exchange plates 17 and are fixed to two sets of sealing head plates 14. The liquid flow caps 19 at both ends not only seal the cold water flow pipes 18, but also, through multiple through holes, cooperate with the turbulence columns 21 within the cold water flow pipes 18 to change the flow state of the cold water inside the pipes. Through the arrangement of the cold water flow pipes 18, liquid flow caps 19, through holes, and turbulence columns 21, complex flow patterns are formed within the pipes, further enhancing fluid turbulence and promoting more complete heat transfer from the high-temperature region to the cold water, thus improving overall heat exchange efficiency. The sealing caps 24 on both sides of the packaging shell 11 have multiple perforations for the insertion of the multiple sets of cold water flow pipes 18 at both ends. The sealing caps 24 seal both sides of the packaging shell 11 and, through the perforations, cooperate with the cold water flow pipes 18 to achieve connection and positioning of the internal and external pipes. With the cover 24, perforation, and cold water pipe 18, the device ensures overall airtightness while facilitating the inlet and outlet of cold water and the installation layout of the device. The sealing ring 25 fitted on the cover 24 fits against the packaging shell 11 at one end, enhancing the seal between the cover 24 and the packaging shell 11 and preventing heat loss and the entry of external impurities.

[0027] Multiple sets of connection holes on the packaging shell 11, composite layer, and pressurized water tank 13, along with hot water inlet and outlet pipes 26 installed thereon, provide channels for hot water flow and connection to external heating systems. Through the sealing ring 25, the connection holes, and the hot water inlet and outlet pipes 26, the device ensures smooth hot water output and connection to external heating facilities while maintaining good sealing. The placement feet 29 fitted at the bottom of the packaging shell 11 support the entire device, making it more stable and preventing direct contact between the bottom of the device and the ground, reducing the risk of moisture and corrosion and extending the device's service life.

[0028] The specific usage and function of this embodiment are as follows:

[0029] When the gas-fired heating and hot water boiler is running, cold water flows into the housing shell 12 from the cold water inlet / outlet pipe 28, and after being filtered by the filter plate 27, it enters the pressurized water tank 13. The housing shell 11 provides overall protection, and its internal composite insulation layer 22 is made of glass wool, which fits against the pressurized water tank 13 to reduce heat loss. The reinforcing frame 23 enhances the structural strength. Inside the pressurized water tank 13, the sealing head plate 14 is fixed to the inner walls on both sides and connected by the connecting column 15. The connecting column 15 is fitted with the clamping block 16, which clamps the heat exchange plate 17. Its flow corrugation enhances heat exchange. The cold water flow pipe 18 passes through it, and the flow cover 19 at both ends cooperates with the internal turbulence column 21 to make the cold water flow turbulently and improve the heat exchange efficiency. The sealing cover 24 is installed on both sides of the housing shell 11, and the cold water flow pipe 18 passes through its perforation. The sealing ring 25 enhances the sealing performance. Finally, the hot water flows out through the hot water inlet / outlet pipe 26 to provide heating or domestic hot water for users. The foot cover 29 ensures the placement of the device.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
