Description

Technical Field

[0001] This utility model relates to a heat exchanger structure for wall-hung boilers that is easy to clean and maintain, and belongs to the field of wall-hung boiler technology. Background Technology

[0002] A wall-hung boiler, short for gas-fired wall-hung boiler, is a type of water heater that uses natural gas as its energy source. It features multiple safety protection measures, including anti-freeze protection, anti-dry-burning protection, accidental flameout protection, overheat protection, and water pump anti-seize protection. The heat exchanger is a crucial component of the wall-hung boiler, transferring some of the heat from a hot fluid to a cold fluid. Plate heat exchangers are commonly used in wall-hung boilers. A plate heat exchanger is a highly efficient heat exchanger composed of a series of corrugated metal plates stacked together. Thin rectangular channels are formed between the plates, facilitating heat exchange. Plate heat exchangers are ideal for liquid-liquid and liquid-vapor heat exchange, characterized by high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life.

[0003] Chinese Patent Publication No. (CN 216620316 U) discloses a heat exchanger structure for a gas-fired wall-hung boiler that is easy to clean. The structure includes a heat exchanger body with a top plate and a bottom plate fixedly installed at its top and bottom, respectively. Heat dissipation plates are provided on both sides of the heat exchanger body. An installation groove is formed inside each heat dissipation plate, and a limiting groove is formed on one side of each heat dissipation plate corresponding to the outer ring of the installation groove. An installation plate is snapped into the installation groove, and a fixing plate is fixedly connected to the outer ring of the surface of the installation plate. This easy-to-clean heat exchanger structure for a gas-fired wall-hung boiler, through the design of the installation groove, limiting groove, installation plate, fixing plate, and installation bolts, facilitates the installation and disassembly of the heat exchanger pipe openings by the user. This avoids the situation where the heat dissipation plate is fixedly connected to the heat exchanger pipes, preventing the inability to disassemble it. It assists in the subsequent disassembly of the heat dissipation plate and simplifies the user's operation. The above structure mainly uses multiple bolts to facilitate the disassembly and assembly of the heat exchanger plate, thereby enabling convenient cleaning and maintenance of the heat exchanger's interior. However, each time the heat exchanger plate is disassembled or assembled, it is necessary to use professional tools to repeatedly tighten the bolts, which is a rather cumbersome process. In addition, due to the small size of the bolts, bolts may be lost after the heat exchanger plate is disassembled, resulting in the inability to completely secure the heat exchanger plate, making it inconvenient for operators to use.

[0004] Therefore, a heat exchanger structure for wall-hung boilers that is easy to clean and maintain is proposed. Utility Model Content

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] Please see Figures 1-6 In this embodiment of the utility model, a heat exchanger structure for a wall-hung boiler that is easy to clean and maintain includes: The heat exchanger assembly 1 includes a heat exchanger body 101. A first cavity 102 is provided at the bottom of the inner surface of the heat exchanger body 101. A second cavity 103 is provided on both the left and right sides of the heat exchanger body 101. A third cavity 104 is provided on both the left and right sides of the heat exchanger body 101. A heat dissipation plate 105 is provided in the inner cavity of each of the two third cavities 104. A heat dissipation mesh 106 is embedded on the surface of each of the two heat dissipation plates 105. Insertion holes 107 are provided on both the front and rear sides of each of the two heat dissipation plates 105. Assembly / disassembly component 2 includes a knob 201, which is movably connected to the front side of the heat exchanger body 101. A bidirectional screw 202 is fixedly connected to the rear side of the knob 201. Screw blocks 203 are threaded onto both the front and rear sides of the surface of the bidirectional screw 202. Moving blocks 204 are fixedly installed on the left and right sides of the two screw blocks 203. Vertical rods 205 are fixedly installed on the tops of the four moving blocks 204. Slide plates 206 are fixedly installed on the tops of the four vertical rods 205. Insert blocks 207 are fixedly installed on the surfaces of the four slide plates 206. The threads on the front and rear sides of the surface of the bidirectional screw 202 are in opposite directions. The threads on the front and rear sides are aligned. By setting up the disassembly and assembly component 2 and rotating the knob 201, the slide plate 206 moves the insertion block 207 outward, thereby removing the insertion block 207 from the inner cavity of the insertion hole 107 and disassembling the heat exchange plate 105. The quick disassembly and assembly of the heat exchange plate 105 allows operators to easily maintain and clean the inner cavity of the heat exchanger body 101. Compared with the traditional use of bolts for fixing, it saves the step of repeatedly tightening bolts and avoids the situation where bolts are accidentally lost, resulting in the heat exchange plate 105 not being fully fixed, making it convenient for operators to use.

[0023] In this embodiment, preferably, each of the four second cavities 103 has a guide hole 208 on its inner side. The insert block 207 passes through the inner cavity of the guide hole 208 and is inserted into the inner cavity of the insertion hole 107. The inner cavity of the guide hole 208 and the inner cavity of the insertion hole 107 are interconnected. The size of the inner cavity of the guide hole 208 and the size of the inner cavity of the insertion hole 107 are consistent with each other. By setting the guide hole 208, the movement of the insert block 207 can be limited to avoid the insert block 207 from deviating when it moves.

[0024] In this embodiment, preferably, each of the four second cavities 103 has a movable groove 209 at its bottom, and the vertical rod 205 passes through the inner cavity of each of the four movable grooves 209 and extends into the inner cavity of the second cavity 103. By setting the movable grooves 209, the movement of the vertical rod 205 can be limited, ensuring the accuracy of the linear movement of the vertical rod 205.

[0025] In this embodiment, preferably, guide rods 210 are fixedly installed on both the left and right sides of the inner cavity of the first cavity 102, and four moving blocks 204 are slidably connected to the surfaces of two guide rods 210. By setting the guide rods 210, the movement of the moving blocks 204 can be limited to prevent the moving blocks 204 from changing direction when moving.

[0026] In this embodiment, preferably, limit rods 211 are fixedly installed on both the left and right sides of the inner cavity of the first cavity 102, and the two screw blocks 203 are slidably connected to the surfaces of the two limit rods 211. By setting the limit rods 211, the movement of the screw blocks 203 can be limited, preventing the screw blocks 203 from rotating synchronously with the bidirectional screw 202.

[0027] In this embodiment, preferably, baffles 108 are provided on both the left and right sides of the heat exchanger body 101, and mounting bolts 109 are threadedly connected to the surfaces of the two baffles 108. By providing baffles 108 and mounting bolts 109, it is convenient to maintain and repair the components in the inner cavities of the first cavity 102 and the second cavity 103.

[0028] When this utility model is in operation: when it is necessary to maintain and clean the components in the inner cavity of the heat exchanger body 101, firstly, by rotating the knob 201, the knob 201 drives the bidirectional screw 202 to rotate. The bidirectional screw 202 drives the screw block 203 and the moving block 204 to move outward, so that the moving block 204 simultaneously drives the vertical rod 205, the sliding plate 206 and the insertion block 207 to move outward. The insertion block 207 moves out of the inner cavity of the insertion hole 107. Then, the heat dissipation plate 105 is pulled to both sides, so that the heat dissipation plate 105 is detached from the inner cavity of the third cavity 104, thus completing the disassembly and assembly of the heat dissipation plate 105. The operator can then perform maintenance and cleaning of the components inside the heat exchanger body 101. After cleaning, the heat sink 105 is placed in the inner cavity of the third cavity 104. Then, the knob 201 is rotated in the opposite direction, causing the bidirectional screw 202 to move the screw block 203 and the moving block 204 inward. The moving block 204 moves the vertical rod 205, the sliding plate 206 and the insertion block 207 inward simultaneously. The insertion block 207 is inserted into the inner cavity of the insertion hole 107, thus completing the installation of the heat sink 105.

Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
