Description

Technical Field

[0001] This utility model relates to the field of water heaters, and in particular to a heat exchanger installation assembly and a water heater including the same. Background Technology

[0002] In the water heater industry, heat exchangers play a crucial role, their primary function being the efficient transfer of heat. Currently, most water heaters on the market employ traditional heat exchanger designs, typically featuring a four-sided enclosed shell with air inlets and outlets only at the top and bottom of the fins. This type of heat exchanger requires complex bending, pipe threading, and welding processes during manufacturing, resulting in a cumbersome and time-consuming assembly process. Furthermore, existing heat exchangers often include coiled heat exchange tubes, which are prone to heat loss in the coiled portion outside the heat exchanger shell. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art, such as the difficulty in assembling heat exchangers and the easy loss of heat from exposed coil parts, and to provide a heat exchanger installation assembly and a water heater including the assembly.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A heat exchanger mounting assembly includes a heat exchanger and a housing. The heat exchanger includes heat exchange tubes and side plates arranged at both ends of the heat exchange tubes. The two ends of the heat exchange tubes pass through the housing and / or the side plates, respectively. The heat exchange tubes include coils protruding from the outer side of the housing and / or the side plates. The heat exchanger mounting assembly also includes heat protection plates, which are plate-shaped structures disposed at both ends of the heat exchange tubes away from the heat exchanger. The two ends of the heat protection plates are fixedly connected to the housing and / or the side plates. The heat protection plates extend in the peripheral space of the coils and position the coils between the side plates and the heat protection plates.

[0006] In this design, a heat shield is installed, extending around the coil and positioning the coil between the side plate and the heat shield. The heat shield has better thermal conductivity than air, and its arrangement facilitates heat flow and conducts heat back to the side plate structure of the heat exchanger through a fixed connection, thereby reducing heat loss. In addition, the heat shield also provides protection, preventing damage to the heat exchanger from impacts during disassembly and assembly.

[0007] Preferably, the heat shield is bent as a whole and forms a bend in the direction away from the heat exchanger to accommodate the coil at the corresponding position.

[0008] Preferably, a limiting boss protruding away from the heat exchanger is provided on the end face of the bent portion, and an antifreeze heating block is provided inside the limiting boss.

[0009] In this design, an antifreeze heating block is installed within the limiting boss. When the heat exchanger operates at low temperatures, the exposed coil portion is heated by the antifreeze heating block to prevent the coil from freezing and affecting or damaging the heat exchanger. The limiting boss ensures that the antifreeze heating block is fixed between the heat protection plate and the coil, preventing it from moving. The antifreeze heating block is mounted on the heat protection plate, and its fixation is indirectly achieved through the connection between the heat protection plate and the heat exchanger housing or side plate. This ensures the stability of the antifreeze heating block installation while avoiding the risk of drilling holes in the coil or heat exchanger that would reduce structural strength or cause leakage. Furthermore, the antifreeze heating block is located within the limiting boss, on the side of the heat protection plate closest to the coil. The heat protection plate also guides the heat from the heating block to the side plate area, further preventing heat loss and improving heating efficiency.

[0010] Preferably, the limiting bosses are spaced apart on the heat protection plate and extend along the length of the coil. This arrangement ensures that the shape of the limiting bosses corresponds to the shape of the coil, improving heat conduction and aligning the position of the antifreeze heating block with the coil portion, thus enhancing heating efficiency and preventing heat loss.

[0011] Preferably, a notch is formed on at least one face of the housing, and the side panel closes the notch and is connected to the side of the housing to form an integral part.

[0012] In this solution, the design of the outer shell and side plate structure allows the side plates to replace part of the outer surface of the heat exchanger. During assembly, after the width between the side plates is determined by those skilled in the art, the internal components of the heat exchanger are fixed, and the side plates are inserted from both ends before the heat exchange tubes are inserted. This completes the assembly of the heat exchanger without needing to consider the assembly of the front and back surfaces of the heat exchanger shell, excluding the side plate positions at both ends. This shortens the assembly time, reduces the material used on the remaining outer surfaces of the heat exchanger, lowers costs, and improves the assembly efficiency of the heat exchanger. The heat exchange tubes are inserted into the side plates through flanged holes; by using flanged holes instead of through holes, the structural strength of the side plates is improved.

[0013] Preferably, the outer peripheral edges of the side plates are bent away from the heat exchanger to form flanges perpendicular to the side plates; the flanges include a first flange distributed along the length direction of the side plates and a second flange distributed along the width direction of the side plates. By bending the outer peripheral edges of the side plates, flanges are formed to enhance the structural strength of the outer shell.

[0014] Preferably, the first flange extends and bends inward again relative to the side plate to form a third flange perpendicular to the first flange and parallel to the side plate. Both ends of the heat-protecting plate abut against the end face of the third flange away from the side plate and are fixedly connected to the third flange. By bending the first flange again, a third flange with higher strength and stability is formed. The heat-protecting plate is then installed and fixed via the third flange, increasing the stability of the heat-protecting plate installation. This allows the heat-protecting plate to abut against the installation end face of the third flange near the heat-protecting plate, enabling the heat-protecting plate to conduct heat to the third flange and then back to the side plate, improving the heat conduction effect and preventing heat loss.

[0015] Preferably, mounting holes are provided at both ends of the heat shield plate, and screw holes corresponding to the mounting holes are provided at intervals on the third flange. Screws pass through the mounting holes and screw holes to connect the heat shield plate to the side plate on the third flange. The screw connection method makes the connection between the heat shield plate and the side plate more stable, reliable, simple and quick, and facilitates assembly and disassembly.

[0016] Preferably, a gap is left between the first flange and the second flange. By leaving a gap, it is convenient for operators to insert the sealant applicator through the gap to apply sealant during the assembly of the heat exchanger, thereby improving assembly efficiency.

[0017] This utility model also provides a water heater, which includes the heat exchanger mounting assembly described above.

[0018] The positive and progressive effects of this utility model are as follows: by setting up a heat shield, the heat shield extends in the space around the coil and the coil is located between the side plate and the heat shield. The heat shield has better thermal conductivity than air. Through the arrangement of the heat shield, it plays a role in guiding heat and conducts heat back to the shell or side plate of the heat exchanger through the fixed connection, thereby reducing heat loss. In addition, setting up a heat shield can also play a protective role, avoiding impact damage to the heat exchanger during disassembly and assembly. Attached Figure Description

[0041] Gap 5 Detailed Implementation

[0042] The present invention will be described more clearly and completely below with reference to the accompanying drawings, but this does not limit the scope of the present invention to the present invention.

[0043] like Figures 1-6 As shown, this embodiment provides a heat exchanger 1 mounting assembly, which includes a heat exchanger 1 and a housing 2. The heat exchanger 1 includes a heat exchange tube 3 and side plates 20 arranged at both ends of the heat exchange tube 3. The two ends of the heat exchange tube 3 pass through the housing 2 and / or the side plates 20, respectively. The heat exchange tube 3 includes a coil 31 exposed on the outside of the housing 2 and / or the side plates 20. The heat exchanger 1 mounting assembly also includes a heat protection plate 4. The heat protection plate 4 is a plate-shaped structure arranged on the side away from the heat exchanger 1 at both ends of the heat exchange tube 3. The two ends of the heat protection plate 4 are fixedly connected to the housing 2 and / or the side plates 20. The heat protection plate 4 extends in the peripheral space of the coil 31 and places the coil 31 between the side plates 20 and the heat protection plate 4.

[0044] In this embodiment, by setting a heat shield 4, the heat shield 4 extends in the peripheral space of the coil 31 and the coil 31 is located between the side plate 20 and the heat shield 4. The heat shield 4 has better thermal conductivity than air. Through the arrangement of the heat shield 4, it plays a role in guiding heat and conducts the heat back to the side plate 20 structure of the heat exchanger 1 through the fixed connection, so as to reduce heat loss. In addition, setting the heat shield 4 can also play a protective role, avoiding impact damage to the heat exchanger 1 during disassembly and assembly.

[0045] In the specific implementation process, the number of heat protection plates 4 can be adjusted and arranged according to the number of exposed coil 31 parts of heat exchange tube 3, which can all play a heat conduction effect and prevent heat loss.

[0046] like Figure 1 , Figure 4 and Figure 5 As shown, the heat shield 4 is bent as a whole and forms a bend 41 in the direction away from the heat exchanger 1 to accommodate the coil 31 at the corresponding position. A limiting boss 42 protruding in the direction away from the heat exchanger 1 is provided on the end face of the bend 41, and an antifreeze heating block 43 is provided inside the limiting boss 42. In this embodiment, by providing the antifreeze heating block 43 inside the limiting boss 42, when the heat exchanger 1 is operating at low temperatures, the exposed portion of the coil 31 is heated by the antifreeze heating block 43 to prevent the coil 31 from freezing and affecting or damaging the heat exchanger 1; the setting of the limiting boss 42 ensures that the antifreeze heating block 43 is fixed between the heat shield 4 and the coil 31 and does not move; the antifreeze heating block 43 is set on the heat shield 4, and the connection between the heat shield 4 and the outer shell 2 or the side plate 20 indirectly achieves... The current method of fixing the antifreeze heating block 43 can ensure the stability of the antifreeze heating block 43 installation and fixation, while avoiding the risk of drilling holes in the coil 31 or heat exchanger 1 to reduce the structural strength or cause liquid or gas leakage. The antifreeze heating block 43 is located in the limiting boss 42, that is, on the side of the heat protection plate 4 near the coil 31. The heat protection plate 4 can play a role in guiding the heat of the heating block, guiding the heat of the antifreeze heating block 43 to the side plate 20 area, further preventing heat loss and improving the heating effect.

[0047] In other embodiments, those skilled in the art can determine the specifications, quantity, location, or absence of the antifreeze heating block 43 according to actual needs. It can also serve the purpose of conducting heat through the heat protection plate 4 and preventing heat loss as described in this application.

[0048] like Figure 1 , Figure 4 and Figure 5Limiting bosses 42 are spaced apart on the heat-protecting plate 4 and extend along the length of the coil 31. By setting them, the shape and extension direction of the limiting bosses 42 correspond to the coil 31, improving the heat conduction effect, and the position of the antifreeze heating block 43 corresponds to part of the coil 31, improving the heating effect and preventing heat loss.

[0049] In other embodiments, those skilled in the art can design the shape and extension direction of the limiting boss 42 according to actual needs, so as to correspond with the coil 31. All of these can facilitate the installation of the antifreeze heating block 43 to improve the installation stability of the antifreeze heating block 43, and optimize the heat conduction and heating effect through the heat protection plate 4.

[0050] like Figure 6 As shown, a notch is formed on at least one surface of the outer shell 2, and the side plate 20 closes the notch and is connected to the side of the outer shell 2 to form an integral unit. Through the design of the structure of the outer shell 2 and the side plate 20, the side plate 20 replaces part of the outer surface of the outer shell 2. During assembly, after the width between the side plates 20 is determined by those skilled in the art, the internal components of the heat exchanger 1 are fixed, and the side plates 20 are inserted from both ends before the heat exchange tubes 3 are inserted to complete the assembly of the heat exchanger 1. There is no need to consider the assembly of the front and back surfaces of the outer shell 2, except for the positions of the side plates 20 at both ends, thereby shortening the assembly time, reducing the material used on the remaining outer surfaces of the outer shell 2, reducing costs, and improving the assembly efficiency of the heat exchanger 1. The heat exchange tubes 3 are inserted into the side plate 20 through flanged holes 200. By using flanged holes 200 instead of through holes, the structural strength of the side plate 20 can be improved. In other embodiments, the connection structure can be designed according to actual needs to facilitate the insertion and positioning of the coils 31.

[0051] like Figures 1-4 As shown, the outer peripheral edges of the side plate 20 are all bent away from the heat exchanger 1 to form flanges perpendicular to the side plate 20; the flanges include a first flange 21 distributed along the length direction of the side plate 20 and a second flange 22 distributed along the width direction of the side plate 20. By bending the outer peripheral edges of the side plate 20, flanges are formed to strengthen the structural strength of the outer shell 2.

[0052] like Figures 1-3As shown, the first flange 21 extends and bends inward relative to the side plate 20 to form a third flange 23 perpendicular to the first flange 21 and parallel to the side plate 20. Both ends of the heat-protecting plate 4 abut against the end face of the third flange 23 away from the side plate 20 and are fixedly connected to the third flange 23. By bending the first flange 21 again, a third flange 23 with higher strength and stability is formed. The heat-protecting plate 4 is then installed and fixed via the third flange 23, increasing the stability of the heat-protecting plate 4 installation. This allows the heat-protecting plate 4 to abut against the third flange 23 near its mounting end face, enabling the heat-protecting plate 4 to conduct heat to the third flange 23 and then back to the side plate 20, improving the heat conduction effect and preventing heat loss.

[0053] like Figure 1 , Figure 4 and Figure 5 As shown, mounting holes 44 are provided at both ends of the heat-protecting plate 4, and screw holes 231 corresponding to the mounting holes 44 are provided at intervals on the third flange 23. Screws pass through the mounting holes 44 and screw holes 231 to connect the heat-protecting plate 4 and the side plate 20 to the third flange 23. The screw connection method makes the connection between the heat-protecting plate 4 and the side plate 20 more stable and reliable.

[0054] In this embodiment, the screw connection method is relatively reliable, simple, and easy to assemble and disassemble. In other embodiments, operators can also design and select other fixed connection methods such as welding as needed, all of which can enable the heat protection plate 4 to conduct heat and prevent heat loss.

[0055] like Figure 3 As shown, a gap 5 is left between the first flange 21 and the second flange 22. By leaving a gap 5, it is convenient for operators to insert the glue applicator through the gap 5 to apply sealant when assembling the heat exchanger 1, thereby improving assembly efficiency.

[0056] This embodiment also provides a water heater, which includes the heat exchanger 1 mounting assembly described above.
