Description

Technical Field

[0001] The utility model relates to the technical field of heating, in particular to a spoiler spring, a heat exchange component and a gas water heater. Background Art

[0002] A gas water heater uses gas as fuel, heating water through combustion, transferring heat to cold water flowing through a heat exchanger assembly to produce hot water. During use, the heat exchanger assembly of a gas water heater is prone to supercooling and boiling, causing water to vaporize on the inner walls of the heat exchanger tubes. This vaporization produces a humming noise, which can be detrimental to the user experience.

[0003] In order to avoid excessive noise during the operation of the gas water heater, a spoiler spring assembly is generally provided in the heat exchange tube of the heat exchange assembly in the prior art. Figure 1-Figure 3 As shown, the spoiler spring assembly includes a spring 10 and a spoiler 20 mounted on the inner ring of the spring 10. The spoiler 20 is generally twisted in a spiral shape. After water flows through the spoiler spring assembly, the water flow changes from laminar flow to turbulent flow, reducing water vaporization and thus reducing the water vaporization noise.

[0004] However, during assembly of the aforementioned spoiler spring assembly, the spoiler 20 needs to be assembled into the inner coil of the spring 10. To prevent relative displacement between the spoiler 20 and the spring 10 after assembly, which could affect the normal operation of the spoiler spring assembly, the largest cross-sectional area of the spoiler 20 is in a tight contact with the inner coil of the spring 10. Since the spoiler 20 has multiple largest cross-sectional areas, assembly of the spoiler spring assembly is time-consuming and labor-intensive. Utility Model Content

[0005] One of the technical problems solved by the present invention is to provide a spoiler spring, which can effectively solve the technical problem in the prior art that the assembly is time-consuming and labor-intensive when the spoiler needs to be assembled into the spring.

[0006] The second technical problem solved by the present invention is to provide a heat exchange assembly, which can effectively solve the technical problem in the prior art that the assembly is time-consuming and labor-intensive when the spoiler needs to be assembled into the spring.

[0007] The third technical problem solved by the present invention is to provide a gas water heater, which can effectively solve the technical problem in the prior art that the spoiler needs to be assembled into the spring, which causes time-consuming and labor-intensive assembly.

[0008] The first technical problem mentioned above is solved by the following technical solution:

[0009] A spoiler spring comprises a plurality of spoilers connected in series and a plurality of coaxially arranged spiral supports, wherein the spoilers and the spiral supports are alternately arranged and projected along the axial direction of the spiral supports. The projection of each spoiler is located within the inner ring projection of the spiral support, and the projections of at least two spoilers do not overlap.

[0010] Compared with the background technology, the spoiler spring of the present invention has the following beneficial effects:

[0011] When in use, the spoiler spring proposed in the utility model is installed in the heat exchange tube of the heat exchange assembly of the gas water heater, and the spoiler spring is arranged coaxially with the heat exchange tube. Due to the presence of multiple spoilers, and the projections of at least two spoilers along the axial direction of the spiral support member do not overlap, such an arrangement is equivalent to at least two spoilers with different orientations, that is, it is equivalent to setting multiple blocking members in the direction of the water flow, and at least two blocking members have different blocking angles. When the water flows along the axial direction of the spoiler spring, there will be a spoiler that can disrupt the flow in the water flow cross section every time it passes through a spiral support member. The multiple spoilers can play a role in strengthening the flow disturbance, changing the water flow from laminar flow to turbulent flow, reducing water vaporization, and thus reducing vaporization noise. In this way, the spoiler spring can maintain a good flow disturbance effect and eliminate the spoiler in the prior art, which can not only save the process of assembling the spoiler, but also reduce material costs and labor costs.

[0012] In one embodiment, when projected along the axial direction of the spiral support, the projection of each of the spoilers extends along the radial direction of the inner ring of the spiral support.

[0013] In one embodiment, when projected along the axis of the spoiler spring, the included angles between the projections of any two adjacent spoilers are the same.

[0014] In one embodiment, the number of the spoilers is: the ratio of 360° to the angle between two adjacent spoilers.

[0015] In one embodiment, when projected along the axis of the spoiler spring, the angle between the projections of two adjacent spoilers is not less than a set angle.

[0016] In one embodiment, the spoiler is in a straight line shape.

[0017] In one embodiment, among two adjacent spiral support members, the end of one of the spiral support members is connected to one end of the spoiler, and the other end of the spoiler is connected to the front end of the other spiral support member.

[0018] In one embodiment, the spoiler is provided at the free end of at least one of the two spiral support members located at both ends.

[0019] The second technical problem mentioned above is solved by the following technical solution:

[0020] Heat exchange components, including:

[0021] heat exchange tubes;

[0022] The above-mentioned flow-disturbing spring is arranged inside the heat exchange tube along the axial direction of the heat exchange tube.

[0023] Compared with the background technology, the heat exchange component of the present invention has the following beneficial effects:

[0024] When the heat exchange assembly proposed by the present invention is in operation, a flow-disturbing spring is installed in the heat exchange tube of the heat exchange assembly. Due to the presence of multiple flow-disturbing parts of the flow-disturbing spring, and the projections of at least two flow-disturbing parts along the axial direction of the spiral support, the projections do not overlap. Such an arrangement is equivalent to providing multiple blocking parts in the direction of the water flow, and the blocking angles of at least two blocking parts are different. When the water flows along the axial direction of the flow-disturbing spring, a flow-disturbing part will be present in the cross section of the water flow each time it passes through a spiral support. The multiple flow-disturbing parts can enhance the flow disturbance, change the water flow from laminar flow to turbulent flow, reduce water vaporization, and thus reduce vaporization noise. In this way, the flow-disturbing spring can maintain a good flow-disturbing effect and eliminate the spoiler in the prior art. This can eliminate the process of assembling the spoiler and reduce material and labor costs.

[0025] The third technical problem mentioned above is solved by the following technical solution:

[0026] Gas water heater, including:

[0027] heat exchange room;

[0028] The above-mentioned heat exchange component is arranged in the heat exchange chamber and exchanges heat with the high-temperature flue gas in the heat exchange chamber.

[0029] Compared with the background technology, the gas water heater of the present invention has the following beneficial effects:

[0030] The heat exchange assembly of the gas water heater proposed by the present invention has the aforementioned flow-disrupting spring installed inside its heat exchange tube. When the gas water heater is in operation, due to the presence of multiple flow-disrupting parts of the flow-disrupting spring, and the projections of at least two flow-disrupting parts along the axis of the spiral support, do not overlap. This arrangement is equivalent to providing multiple blocking parts in the direction of the water flow, and at least two blocking parts have different blocking angles. When the water flows along the axial direction of the flow-disrupting spring, each time it passes through a spiral support, a flow-disrupting part will be present in the cross-section of the water flow. The multiple flow-disrupting parts can enhance the flow disturbance, changing the water flow from laminar flow to turbulent flow, reducing water vaporization, and thereby reducing vaporization noise. In this way, the flow-disrupting spring can maintain a good flow-disrupting effect and eliminate the spoiler used in the prior art. This not only eliminates the process of assembling the spoiler, but also reduces material and labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Example 1

[0050] See also Figure 4-Figure 8 This embodiment provides a spoiler spring, which is applied to the heat exchange component of the gas water heater and installed in the heat exchange tube of the heat exchange component to reduce the vaporization noise generated by the heat exchange component during operation and improve the user experience.

[0051] Specifically, see Figure 7 and Figure 8 In this embodiment, the spoiler spring includes a plurality of spoilers 2 connected in series and a plurality of coaxially arranged spiral support members 1. The spoilers 2 and the spiral support members 1 are arranged alternately. Projected along the axis of the spiral support member 1, the projection of each spoiler 2 is located within the projection of the inner circle of the spiral support member 1, and the projections of at least two spoilers 2 do not overlap. The projections of at least two spoilers 2 do not overlap, that is, at least two spoilers 2 are oriented in different directions.

[0052] The spoiler spring provided in this embodiment is installed in the heat exchange tube of the heat exchange assembly of the gas water heater when in use, and the spoiler spring is arranged coaxially with the heat exchange tube. Due to the presence of multiple spoilers 2, and the projection along the axial direction of the spiral support 1, the projections of at least two spoilers 2 do not overlap. Such an arrangement is equivalent to providing multiple blocking members in the direction of water flow, and the blocking angles of at least two blocking members are different, so as to enhance the effect of flow disturbance. When the water flows along the axial direction of the spoiler spring, each time it passes through a spiral support 1, there will be a spoiler 2 that can disrupt the flow in the water flow cross section. The multiple spoilers 2 can enhance the effect of flow disturbance, change the water flow from laminar flow to turbulent flow, reduce the vaporization of water, and thus reduce the vaporization noise. In this way, the spoiler spring can maintain a good flow disturbance effect and eliminate the spoiler in the prior art, which can eliminate the process of assembling the spoiler and reduce material cost and labor cost.

[0053] Specifically, the spiral support member 1 is a spiral spring.

[0054] When the spoiler spring is disturbing the flow, the bubbles generated by vaporization in the water flow may collide with the spoiler 2 or the spring coil of the spiral support 1. After the collision, the bubbles will be broken up or even disappear under the reaction force of the spiral support 1, thereby reducing the vaporization noise of the heat exchange component during operation.

[0055] Optionally, in one embodiment, the spoiler 2 is in a straight line shape, and the straight line spoiler 2 is easy to process and manufacture.

[0056] Of course, in other embodiments, the shape of the spoiler 2 can also be curved, such as a wavy curved strip, or other irregular curved strips. Alternatively, the shape of the spoiler 2 can also be a flattened sheet.

[0057] Specifically, in one embodiment, among two adjacent spiral support members 1 , the end of one spiral support member 1 is connected to one end of the spoiler 2 , and the other end of the spoiler 2 is connected to the front end of the other spiral support member 1 .

[0058] Furthermore, in one embodiment, when projected along the axial direction of the spiral support 1 , the projection of each spoiler 2 extends along the radial direction of the inner ring of the spiral support 1 .

[0059] For this setting, see Figure 8 Each spoiler 2 is arranged to pass through the axis of the spoiler spring. When each spoiler 2 disturbs the water flow, it is located in the middle position of the water flow cross section to ensure sufficient uniformity of the spoiler.

[0060] Optionally, in one embodiment, when projected along the axis of the spoiler spring, the included angles between the projections of any two adjacent spoilers 2 are the same.

[0061] The axial direction of the spiral support member 1 is collinear with the axial direction of the spoiler spring.

[0062] With this arrangement, each time the water flow passes through a spiral support member 1, the spoiler 2 that disturbs the water flow changes along the same angle, ensuring sufficient uniformity of the disturbance, ensuring that the spoiler spring continuously disturbs the water flow with the spoiler 2 with the same disturbing effect, and at the same time ensuring the uniformity of heat exchange of the water flow by the heat exchange tube.

[0063] Of course, in other embodiments, the angles between any two adjacent spoilers 2 may also be set to be different, so that the water flow is more turbulent and the noise reduction effect is better.

[0064] Furthermore, in one embodiment, when projected along the axis of the spoiler spring, the angle between the projections of any two adjacent spoilers 2 is the same, the number of spoilers 2 is: the ratio of 360° to the angle between the two adjacent spoilers 2.

[0065] With such an arrangement, during the flow of water, the angles of the multiple spoilers 2 change continuously and evenly, fully allowing the water flow to continuously bypass the spoilers 2 at different angles, making the flow of water more complex and disordered. This flow will destroy the original laminar flow and can also destroy the bubbles in the water flow, thereby strengthening the flow of water.

[0066] In one embodiment, when projected along the axis of the spoiler spring, the angle between the projections of two adjacent spoilers 2 is not less than a set angle.

[0067] It can be understood that when projected along the axis direction of the spoiler spring, the angle between the projections of any two adjacent spoilers 2 is the same, the number of spoilers 2 is: the ratio of 360° to the angle between the two adjacent spoilers 2; at this time, theoretically, the smaller the angle between the two adjacent spoilers 2, the better. The smaller the angle between the two adjacent spoilers 2, the more spoilers 2 can be, and the better the spoiler effect.

[0068] However, based on the manufacturing difficulty and the length of the heat exchange tube, the angle is optionally set to 5°-30°. Exemplarily, the angle can be set to 5°, 10°, 15°, 20°, 25° or 30°.

[0069] For example, in this embodiment, the angle between two adjacent spoilers 2 is 30°. In this case, the number of spoilers 2 is twelve.

[0070] Of course, in other embodiments, the angle between two adjacent spoilers 2 may also be set to other values as needed, and no further restrictions are imposed herein.

[0071] Optionally, in one embodiment, the spiral support member 1 is a cylindrical spiral spring or a conical spiral spring.

[0072] Both cylindrical coil springs and conical coil springs are easy to process.

[0073] Furthermore, the spiral support member 1 is a cylindrical coil spring. When the spiral support member 1 is manufactured, the outer diameter of the spiral support member 1 is set to be the same as the inner diameter of the heat exchange tube. When the flow-disrupting spring is installed in the heat exchange tube, the outer side of the spiral support member 1 abuts against the inner side of the heat exchange tube, fully limiting the flow-disrupting spring and ensuring the working stability of the flow-disrupting spring.

[0074] Optionally, in one embodiment, the free end of at least one of the two spiral support members 1 at both ends is provided with a spoiler 2. This arrangement can increase the number of spoilers 2 as much as possible and enhance the spoiling effect of the spoiler spring.

[0075] Specifically, in this embodiment, the spiral support member 1 and the spoiler 2 are both made of spring steel to ensure that both can exert a reaction force on the bubbles in the water flow to break or eliminate the bubbles and reduce vaporization noise.

[0076] Alternatively, see Figure 9 , a spoiler tooth 21 can be provided on the spoiler 2. The spoiler tooth 21 is arranged at an angle to the spoiler 2 and parallel to the radial direction of the spiral support member 1 to enhance the flow disturbance effect. Specifically, the length of the spoiler tooth 21 is less than the radius of the spiral support member 1. For example, a plurality of spoiler teeth 21 can be provided on the spoiler 2 along the extension direction of the spoiler 2. The lengths of the spoiler teeth 21 on each spoiler 2 can be set to be the same or different.

[0077] Specifically, if Figure 9 As shown, three spoiler teeth 21 are provided on the spoiler 2 , and the lengths of the three spoiler teeth 21 are different.

[0078] Example 2

[0079] This embodiment provides a heat exchange component.

[0080] Specifically, the heat exchange assembly includes a heat exchange tube and the spoiler spring of embodiment one.

[0081] The spoiler spring is arranged in the heat exchange tube along the axial direction of the heat exchange tube.

[0082] The heat exchange assembly provided in this embodiment can reduce vaporization noise and reduce material and labor costs of the heat exchange assembly by arranging a spoiler spring in the heat exchange tube.

[0083] When the heat exchange assembly is in use, due to the presence of multiple spoilers 2 within the heat exchange tube, and projected along the axial direction of the spiral support member 1, the projections of at least two spoilers 2 do not overlap. This arrangement is equivalent to providing multiple blocking members in the direction of the water flow, and the blocking angles of at least two blocking members are different. When the water flows along the axial direction of the spoiler spring, each time it passes through a spiral support member 1, a spoiler 2 capable of disrupting the flow will be present in the water flow cross-section. The multiple spoilers 2 can enhance the flow disturbance, change the water flow from laminar flow to turbulent flow, reduce water vaporization, and thereby reduce vaporization noise. In this way, the spoiler spring can maintain a good flow disturbance effect and eliminate the spoiler in the prior art, which can not only eliminate the process of assembling the spoiler, but also reduce material and labor costs.

[0084] When the spoiler spring disturbs the water flow in the heat exchange tube, the bubbles generated by vaporization in the water flow may collide with the spoiler 2 or the spring coil of the spiral support 1. After the collision, the bubbles will be broken up or even disappear under the reaction force of the spiral support 1, thereby reducing the vaporization noise of the heat exchange component during operation.

[0085] Example 3

[0086] This embodiment provides a gas water heater.

[0087] The gas water heater includes a heat exchange chamber and the heat exchange component of the second embodiment. The heat exchange component is arranged in the heat exchange chamber and exchanges heat with the high-temperature flue gas in the heat exchange chamber.

[0088] When the gas water heater provided in this embodiment is in operation, the flow-disrupting spring is installed in the heat exchange tube of the heat exchange assembly of the gas water heater, and the flow-disrupting spring is arranged coaxially with the heat exchange tube. Due to the presence of multiple flow-disrupting members 2, and the projections along the axial direction of the spiral support member 1, the projections of at least two flow-disrupting members 2 do not overlap. Such an arrangement is equivalent to providing multiple blocking members in the direction of water flow, and the blocking angles of at least two blocking members are different. When the water flows along the axial direction of the flow-disrupting spring, each time it passes through a spiral support member 1, there will be a flow-disrupting member 2 in the water flow cross section. The multiple flow-disrupting members 2 can play a role in strengthening the flow disturbance, changing the water flow from laminar flow to turbulent flow, reducing the vaporization of water, and thereby reducing the vaporization noise. In this way, the flow-disrupting spring can maintain a good flow-disrupting effect and eliminate the spoiler in the prior art, which can eliminate the process of assembling the spoiler and reduce material and labor costs.

[0089] When the spoiler spring is disturbing the flow, the bubbles generated by vaporization in the water flow may collide with the spoiler 2 or the spring coil of the spiral support 1. After the collision, the bubbles will be broken up or even disappear under the reaction force of the spiral support 1, thereby reducing the vaporization noise of the heat exchange component during operation.

In order to make the description concise, not all possible combinations of the above-mentioned technical features are described.
