DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] See also Figure 1 to Figure 5 A fixing structure of a heat exchanger accessory according to an embodiment of the utility model comprises a fixing seat 1 for fixing and installing the heat exchanger accessory, and a fixing plate 2 fixed on a heat exchange tube 3, wherein the fixing seat 1 is installed on the fixing plate 2, and the fixing seat 1 and the fixing plate 2 are assembled detachably; a limiting hole 231 is provided on the fixing plate 2, a limiting portion 111 is provided at one end of the fixing seat 1, and a connecting portion 112 is provided at the other end, the limiting hole 231 cooperates with the limiting portion 111, so that the fixing plate 2 limits the limiting portion 111, and the connecting portion 112 is used to be connected to the fixing plate 2.

[0030] In this embodiment, the fixing structure includes a fixing seat 1 and a fixing plate 2. The fixing plate 2 is fixed to the outer wall of the heat exchange tube 3. The fixing seat 1 is used to fix and install heat exchanger accessories, such as a thermostat, a water flow sensor, a water pressure sensor and other accessories. The following description takes the thermostat as an example.

[0031] By installing the fixing seat 1 on the fixing plate 2, the thermostat can be installed on the heat exchange tube 3, and the temperature of the outer wall of the heat exchange tube 3 is transmitted to the thermostat through the fixing plate 2 and the fixing seat 1, so that the temperature of the outer wall of the heat exchange tube 3 is monitored by the thermostat, and the water temperature in the heat exchange tube 3 is controlled, thereby realizing the water temperature control in the heat exchanger. Specifically, in actual implementation, the fixing plate 2 can be fixed on the heat exchange tube 3 by welding or other methods, so that the fixing of the fixing plate 2 on the heat exchange tube 3 is more firmly.

[0032] Since the heat exchange tube 3 of the heat exchanger includes multiple heat exchange tubes installed on the heat exchanger frame 4, and the fixing plate 2 is fixed on one of the heat exchange tubes, in the present application, the assembly of the fixing seat 1 and the fixing plate 2 is detachable, so that the fixing seat 1 and the thermostat can be installed and disassembled on the heat exchange tube 3.

[0033] When assembling the heat exchanger, multiple heat exchange pipes can be installed on the heat exchanger frame 4 first, the fixing plate 2 is pre-fixed on one of the heat exchange pipes, and then the fixing seat 1 is installed on the fixing plate 2, and the thermostat is installed on the heat exchange pipe, thereby preventing the previously installed thermostat from hindering the installation of other heat exchange pipes, thereby making the assembly of the heat exchanger simpler, more convenient and easier to implement.

[0034] Specifically, in the present application, a limiting hole 231 is provided on the fixing plate 2, a limiting portion 111 is provided at one end of the fixing seat 1, and a connecting portion 112 is provided at the other end. When the fixing seat 1 is installed on the fixing plate 2, the limiting portion 111 at one end of the fixing seat 1 is first matched with the limiting hole 231 on the fixing plate 2, and the fixing plate 2 limits one end of the fixing seat 1 through the matching of the limiting hole 231 and the limiting portion 111.

[0035] Then the connecting portion 112 at the other end of the fixing plate 2 is connected to the fixing plate 2, thereby completing the fixed connection between the fixing base 1 and the fixing plate 2. The thermostat is fixedly mounted on the fixing base 1, so that the installation of the thermostat in the heat exchanger is simpler and more convenient, and easy to implement, thereby making the assembly of the heat exchanger simple and convenient, and improving production efficiency.

[0036] Specifically, in this embodiment, the limiting portion 111 can cooperate with the limiting hole 231 by plugging, snapping, etc., and the plugging method is used as an example below, that is, the limiting portion 111 is plugged into the limiting hole 231 to limit one end of the fixing seat 1 by the fixing plate 2.

[0037] In this embodiment, the connecting portion 112 is provided with a first through hole 1121, the fixing plate 2 is provided with a first connecting hole 211, and the fixing structure further includes a first connecting member having one end passing through the first through hole 1121 and connected to the first connecting hole 211. In the present application, the connecting portion 112 at the other end of the fixing seat 1 is provided with a first through hole 1121, and the fixing plate 2 is provided with a first connecting hole 211 at a corresponding position.

[0038] This fixing structure also includes a first connecting member. When the limiting portion 111 at one end of the fixing seat 1 is inserted into the limiting hole 231 of the fixing plate 2, and the first through hole 1121 at the other end of the fixing seat 1 coincides with the central axis of the first connecting hole 211 on the fixing plate 2, one end of the first connecting member passes through the first through hole 1121 and is connected to the first connecting hole 211, thereby fixing the connecting portion 112 at the other end of the fixing seat 1 to the fixing plate 2.

[0039] Specifically, in this embodiment, the first connecting hole 211 can be a threaded hole, and the first connecting member can be a screw or a bolt. After one end of the screw or bolt passes through the first through hole 1121 at the other end of the fixing base 1, it is screwed to the threaded hole on the fixing plate 2, thereby fixing the connecting part 112 at the other end of the fixing base 1 to the fixing plate 2.

[0040] It can be foreseen that when disassembling the fixing seat 1 on the fixing plate 2, the first connecting member can be screwed out from the first connecting hole 211 first, and then the limiting portion 111 and the limiting hole 231 can be pulled out to complete the disassembly of the fixing seat 1 on the fixing plate 2, thereby making the disassembly of the thermostat in the heat exchanger simple and convenient.

[0041] In the prior art, in order to ensure the stability of the thermostat when installed on the heat exchange tube 3, both ends of the fixing base 1 on which the thermostat is installed are usually fixedly connected to the fixing plate 2 by screwing. In the present application, one end of the fixing base 1 is plugged into the fixing plate 2, and the other end is screwed to the fixing plate 2, thereby reducing one screwing process. While ensuring the stability of the thermostat installation, the installation of the thermostat in the heat exchanger is simpler, more convenient, and easier to implement, thereby making the assembly of the heat exchanger simple and convenient, and improving production efficiency.

[0042] In this embodiment, the fixing plate 2 is fixed to the water outlet end of the heat exchange tube 3. In the heat exchanger, the heat exchange tube 3 is arranged on the heat exchanger frame 4, and the water inlet pipe is connected with one end of the heat exchange tube 3 to input cold water into the heat exchange tube 3; when the cold water flows through the heat exchange tube 3, the high-temperature flue gas in the heat exchanger frame 4 exchanges heat with the heat exchange tube 3 to heat the cold water; the water outlet pipe is connected with the other end of the heat exchange tube 3, and the cold water in the heat exchange tube 3 is heated and transported to the water outlet pipe, so that hot water is output through the water outlet pipe, realizing the function of the gas water heater to output hot water.

[0043] Therefore, the water temperature at the water outlet of the heat exchange tube 3 is close to the final output hot water temperature. In the present application, the fixing plate 2 is fixed to the water outlet of the heat exchange tube 3, and then the thermostat is fixed to the water outlet of the heat exchange tube 3 by assembling the fixing seat 1 and the fixing plate 2. The temperature of the water outlet of the heat exchange tube 3 is monitored by the thermostat, and the temperature of the hot water output by the heat exchanger can be controlled more accurately.

[0044] Furthermore, in the present embodiment, the outer contour of the limiting portion 111 at one end of the fixing seat 1 can be set to be the same as the outer contour of the connecting portion 112 at the other end of the fixing seat 1, and the first through hole 1121 is set on both the limiting portion 111 and the connecting portion 112. Therefore, when the fixing seat 1 is connected to the fixing plate 2, the connecting portion 112 can serve as the limiting portion 111 and be plugged into the limiting hole 231 of the fixing plate 2. The limiting portion 111 can also serve as the connecting portion 112 and be fixedly connected to the fixing plate 2 through the first connecting member. Therefore, when the fixing seat 1 is connected to the fixing plate 2, there is no need to distinguish between the two ends of the fixing seat 1. Any one end can be plugged into the limiting hole 231 of the fixing plate 2, and the other end can be fixedly connected to the fixing plate 2 through the first connecting member. This further makes the installation of the thermostat in the heat exchanger simpler and more convenient, and easy to implement, thereby making the assembly of the heat exchanger simple and convenient, and improving production efficiency.

[0045] In this embodiment, the fixing plate 2 includes a first mounting plate 21, a second mounting plate 22, and a third mounting plate 23 disposed between the first mounting plate 21 and the second mounting plate 22. The first mounting plate 21 and the second mounting plate 22 are in an up-and-down staggered structure. The third mounting plate 23 connects the first mounting plate 21 with the second mounting plate 22, and the limiting hole 231 is disposed on the third mounting plate 23. In this application, the fixing plate 2 includes a first mounting plate 21, a second mounting plate 22, and a third mounting plate 23. The third mounting plate 23 is disposed between the first mounting plate 21 and the second mounting plate 22.

[0046] Since the first mounting plate 21 and the second mounting plate 22 are in an up-and-down staggered structure, the third mounting plate 23 connects the first mounting plate 21 and the second mounting plate 22, and a limiting hole 231 is provided on the third mounting plate 23. Therefore, a space for the limiting portion 111 at one end of the fixing seat 1 to be inserted is formed between the first mounting plate 21 and the second mounting plate, so that the limiting portion 111 can pass through the limiting hole 231 and be inserted between the first mounting plate 21 and the second mounting plate, and the limiting portion 111 is limited from both sides by the first mounting plate 21 and the second mounting plate 22 respectively.

[0047] The connection portion 112 at the other end of the fixing seat 1 is screwed to the fixing plate 2 to complete the fixed connection between the fixing seat 1 and the fixing plate 2, which not only ensures the stability of the connection between the fixing seat 1 and the fixing plate 2, but also makes the connection between the fixing seat 1 and the fixing plate 2 simple, convenient and easy to implement.

[0048] In this embodiment, the fixing seat 1 includes a connecting plate 11 installed on the fixing plate 2, and a mounting frame for fixing and mounting the thermostat, the mounting frame is arranged on the connecting plate 11, the limiting portion 111 is arranged at one end of the connecting plate 11, and the connecting portion 112 is arranged at the other end of the connecting plate 11. In the present application, the fixing seat 1 includes a connecting plate 11 and a mounting frame, the limiting portion 111 is arranged at one end of the connecting plate 11, and the connecting portion 112 is arranged at the other end of the connecting plate 11, the limiting portion 111 is plugged with the limiting hole 231 on the fixing plate 2, and the connecting portion 112 is fixedly connected to the fixing plate 2 through the first connecting member, thereby realizing the fixed connection between the connecting plate 11 and the fixing plate 2. The mounting frame is arranged on the connecting plate 11, and the thermostat is fixedly mounted on the mounting frame, thereby realizing the installation of the thermostat in the heat exchanger.

[0049] In this embodiment, the mounting frame includes a support column 12 provided on the connecting plate 11, and two clamping plates 13 relatively spaced apart on the support column 12, the two clamping plates 13 are used to clamp the thermostat, and the spacing between the two clamping plates 13 is adjustable. In the present application, the mounting frame includes a support column 12 and two clamping plates 13 relatively spaced apart on the support column 12, and the thermostat is clamped by the two clamping plates 13, so that the thermostat can be fixedly installed on the mounting frame. The support column 12 is provided on the connecting plate 11, so when the connecting plate 11 is fixedly connected to the fixing plate 2, the thermostat can be installed in the heat exchanger.

[0050] Since the two clamping plates 13 are arranged at a relative interval on the support column 12, by installing the thermostat between the two clamping plates 13, the two clamping plates 13 clamp the thermostat, thereby completing the fixed installation of the thermostat on the mounting frame. Therefore, in the present application, the spacing between the two clamping plates 13 on the support column 12 can be adjusted according to the size of the thermostat, so that the two clamping plates 13 can clamp thermostats of different sizes, that is, thermostats of different sizes can be fixedly installed on the mounting frame, and then thermostats of different models and sizes can be installed in the heat exchanger according to needs, so that the application range of the present fixed structure is wider and more practical.

[0051] Specifically, two slide grooves 121 are relatively spaced apart on the support column 12, and the two clamping plates 13 are respectively slidably connected to the two slide grooves 121. By sliding the two clamping plates 13 in the two slide grooves 121, the spacing between the two clamping plates 13 on the support column 12 can be adjusted, so that the two clamping plates 13 can clamp thermostats of different sizes, that is, thermostats of different sizes can be fixedly installed on the mounting frame, and then thermostats of different models and sizes can be installed in the heat exchanger according to needs, so that the application range of the fixing structure is wider and the practicality is stronger.

[0052] In this embodiment, the clamping plate 13 includes a horizontally arranged sliding connection portion 131, and a clamping portion 132 vertically arranged on the sliding connection portion 131, the sliding connection portion 131 is slidably connected to the slide groove 121, and the clamping portions 132 of the two clamping plates 13 clamp the thermostat. In the present application, the clamping plate 13 includes a sliding connection portion 131 and a clamping portion 132, the sliding connection portion 131 is horizontally arranged, and the horizontal movement of the clamping plate 13 in the slide groove 121 can be achieved by sliding the sliding connection portion 131 with the horizontally arranged slide groove 121, so that the adjustment of the distance between the two clamping plates 13 can be achieved by the horizontal movement of the sliding connection portions 131 of the two clamping plates 13 in the slide groove 121.

[0053] The clamping portion 132 is vertically arranged on the sliding connection portion 131. When the sliding connection portions 131 of the two clamping plates 13 move horizontally in the slide groove 121, the clamping portions 132 of the two clamping plates 13 move closer to each other or farther away from each other. When the clamping portions 132 of the two clamping plates 13 move closer to each other, thermostats of different sizes can be clamped, thereby achieving fixed installation of the thermostat on the fixing seat 1; when the clamping portions 132 of the two clamping plates 13 move away from each other, the clamped thermostat can be loosened, so that the thermostat can be removed from the fixing seat 1, thereby facilitating the installation and removal of the thermostat.

[0054] Further, in the present application, the sliding connection part 131 is provided with a second through hole 1311, the second through hole 1311 is a strip hole, the bottom of the slide groove 121 is provided with a second connection hole 122, and the fixing structure further includes a second connection piece with one end passing through the second through hole 1311 and being screwed with the second connection hole 122. Since the second through hole 1311 is a strip hole, when the thermostat is installed on the fixing seat 1, the sliding connection parts 131 of the two clamping plates 13 can be firstly moved horizontally in the slide groove 121, driving the clamping parts 132 of the two clamping plates 13 to approach each other, so that the clamping parts 132 of the two clamping plates 13 are respectively abutted against the two opposite side surfaces of the thermostat to clamp the thermostat, and then the second connection piece is connected to the second connection hole 122 at the bottom of the slide groove 121 after one end passes through the second through hole 1311 on the sliding connection part 131, so that the two clamping plates 13 are fixed on the support column 12, so that the installation stability of the thermostat on the fixing seat 1 is stronger.

[0055] Specifically, in this embodiment, the second connection hole 122 may be a threaded hole, and the second connection member may be a bolt or a screw. After one end of the bolt or the screw passes through the second through hole 1311 on the sliding connection part 131, it is screwed to the threaded hole at the bottom of the slide groove 121, so that the two clamping plates 13 can be fixed on the support column 12.

[0056] On the contrary, when removing the thermostat from the fixing base 1, the second connecting member can be screwed out from the second connecting hole 122 first, and then the sliding connecting parts 131 of the two clamping plates 13 can be moved horizontally in the sliding groove 121, driving the clamping parts 132 of the two clamping plates 13 away from each other, so that the clamping parts 132 of the two clamping plates 13 are respectively away from the two opposite sides of the thermostat, thereby loosening the thermostat.

[0057] Furthermore, in the present application, a third through hole 1321 is provided on the clamping portion 132. It is foreseeable that threaded holes are provided on two opposite sides of the temperature controller, and the fixing structure further includes a third connecting member, which is a screw or a bolt.

[0058] The clamping parts 132 of the two clamping plates 13 are respectively in contact with the opposite side surfaces of the thermostat. When the thermostat is clamped, the third connecting member can pass through the third through hole 1321 and be screwed to the threaded holes at the corresponding positions on the thermostat to fix the thermostat to the clamping part 132, thereby further making the installation stability of the thermostat on the fixing base 1 stronger.
