Description

Technical Field

[0001] This utility model relates to the field of fuel-fired heater technology, and more specifically, to a heat dissipation pipe and a fuel-fired heater having the same. Background Technology

[0002] A fuel-fired heater is a device that relies on fuel combustion to provide warmth. Due to its high heating efficiency and good heating effect, fuel-fired heaters are widely used in cold regions. Currently, Chinese Patent Publication No. CN110925863A discloses a heater in which the heat generated by fuel combustion is mainly radiated outward through a straight pipe section to achieve the purpose of heating. However, in the existing structure of this type of heater, the straight pipe section used for outward heat radiation is a hollow tubular structure. As a result, when the flue gas generated by fuel combustion flows through the straight pipe section, there is a disadvantage of a small contact area between the straight pipe section and the flue gas. Consequently, there is a disadvantage of low heat exchange efficiency between the straight pipe section and the flue gas. That is, the straight pipe section absorbs less heat from the flue gas and radiates less heat outward, resulting in poor heating effect and low energy utilization of the fuel-fired heater. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a heat dissipation pipe and a fuel-fired heater having the same. When the heat dissipation pipe is applied to a gas heater, it can improve the heating effect of the fuel-fired heater and improve the energy utilization rate.

[0004] This utility model provides a heat dissipation pipe, including a heat dissipation pipe body. A plurality of heat conduction frames are formed circumferentially at intervals on the inner sidewall of the heat dissipation pipe body. Each heat conduction frame extends along the length direction of the heat dissipation pipe body. The inner side of each heat conduction frame and the sidewall of the heat dissipation pipe body form a first channel for supplying flue gas flow. The outer sides of the plurality of heat conduction frames and the sidewall of the heat dissipation pipe body form a second channel for supplying flue gas flow. A plurality of fins are provided on the inner and / or outer sides of the heat conduction frames.

[0005] By employing the heat dissipation tube with the aforementioned structure, this invention increases the contact area between the heat dissipation tube and the flue gas when the flue gas generated by fuel combustion flows through the first and second channels, thanks to the heat-conducting frame and several fins. This allows the heat dissipation tube to more reliably absorb heat from the flue gas and radiate heat outwards. Consequently, when the heat dissipation tube is applied to a gas heater, it improves the heating effect of the fuel heater and increases the energy utilization rate.

[0006] In one possible implementation, each heat conduction frame includes two side plates and a connecting plate for connecting the inner ends of the two side plates. The outer end of each side plate is connected to the inner wall of the heat dissipation pipe body. Several fins on each heat conduction frame are formed on the inner and / or outer sides of the side plates.

[0007] In one possible implementation, each connecting plate is formed into an arc-shaped structure.

[0008] In one possible implementation, each side plate extends from the inner wall of the heat pipe body along the center of the heat pipe body.

[0009] In one possible implementation, several heat-conducting frames are distributed at equal intervals along the circumferential direction of the heat dissipation pipe body.

[0010] In one possible implementation, a plurality of heat-conducting fins are also formed circumferentially at intervals on the inner sidewall of the heat dissipation pipe body, each heat-conducting fin extending from the inner wall of the heat dissipation pipe body along the center of the heat dissipation pipe body.

[0011] In one possible implementation, a number of heat-conducting fins are distributed at equal intervals along the circumferential direction of the heat dissipation pipe body, with some of the heat-conducting fins located in the first channel and the remaining heat-conducting fins located in the second channel.

[0012] In one possible implementation, each heat-conducting fin has an expansion portion at its inner end, with both sides of the expansion portion extending along the circumferential direction of the heat dissipation pipe body.

[0013] A fuel-fired heater includes a housing with a front-opening heat radiation cavity. A protective net is fixed to the front opening of the heat radiation cavity. A burner is fixed inside the heat radiation cavity. An exhaust pipe is fixed to the top of the housing. The fuel-fired heater also includes several heat dissipation pipes. The heat dissipation pipes are fixed in parallel and at intervals in the heat radiation cavity. The heat dissipation pipes are connected end to end in sequence through a first connecting pipe. The first end of the first heat dissipation pipe is connected to the exhaust port of the burner, and the last end of the last heat dissipation pipe is connected to the exhaust pipe.

[0014] When the aforementioned fuel-fired heater uses the aforementioned heat dissipation pipe, the pipe body can more reliably absorb heat from the flue gas and radiate heat outwards. Thus, when the heat dissipation pipe is applied to a gas heater, it can improve the heating effect of the fuel-fired heater and increase the energy utilization rate.

[0015] In one possible implementation, several heat dissipation pipes are fixed at equal intervals in the heat radiation cavity. The first end of the first heat dissipation pipe is connected to the exhaust port of the burner through a second connecting pipe, and the last end of the last heat dissipation pipe is connected to the exhaust pipe through a third connecting pipe. Each heat dissipation pipe is pressed tightly against the rear wall of the heat radiation cavity by at least one clamp. Attached Figure Description

[0023] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] See Figure 1-2As shown in the figure, this application discloses a heat dissipation pipe, including a heat dissipation pipe body 1. A plurality of heat conduction frames 11 are formed circumferentially at intervals on the inner sidewall of the heat dissipation pipe body 1. Each heat conduction frame 11 extends along the length direction of the heat dissipation pipe body 1. The inner side of each heat conduction frame 11 and the sidewall of the heat dissipation pipe body 1 form a first channel 12 for supplying flue gas flow. The outer sides of the plurality of heat conduction frames 11 and the sidewall of the heat dissipation pipe body 1 form a second channel 13 for supplying flue gas flow. A plurality of fins 111 are provided on the inner and / or outer sides of the heat conduction frames 11.

[0025] In this embodiment, each heat conduction frame 11 includes two side plates 112 and a connecting plate 113 for connecting the inner ends of the two side plates 112. The outer end of each side plate 112 is connected to the inner wall of the heat dissipation pipe body 1. A plurality of fins 111 on each heat conduction frame 11 are formed on the inner and / or outer sides of the side plates 112. With this structure, the heat conduction frame can be reliably connected to the inner wall of the heat dissipation pipe body, and has the advantages of high structural strength and strong resistance to deformation. In addition, the fins can be formed on the inner or outer sides of the side plates, or the fins can be formed on the inner or outer sides of the side plates at the same time. Under the action of the fins, the heat conduction efficiency between the heat conduction frame and the flue gas flowing through the first channel and / or the second channel can be improved. In addition, the heat conduction frame is integrally formed with the heat dissipation pipe body, and the fins are integrally formed with the heat conduction frame.

[0026] In this embodiment, each connecting plate 113 is formed into an arc shape structure. By using an arc-shaped connecting plate, it has the advantages of strong resistance to deformation and large contact area with the flue gas flowing through the first and second channels, thereby improving the heat exchange efficiency between the connecting plate, the heat conduction frame, the heat dissipation pipe body and the flue gas.

[0027] In this embodiment, each side plate 112 extends from the inner wall of the heat dissipation pipe body 1 along the center of the heat dissipation pipe body 1. By adopting this structure, the heat conduction frame can form a structure that is wide at the outer end and narrow at the inner end, thereby improving the structural stability and deformation resistance of the heat conduction frame. That is, when the flue gas flows through the first channel and the second channel, the deformation of the heat conduction frame can be effectively avoided.

[0028] In this embodiment, several heat conduction frames 11 are evenly distributed along the circumferential direction of the heat dissipation pipe body 1. By adopting this structure, the heat conduction frames can uniformly exchange heat with the flue gas flowing through the first and second channels, thereby enabling the heat conduction frames and the heat dissipation pipe body to be heated uniformly, and thus improving the uniformity of heat radiation when the heat dissipation pipe body radiates heat outward.

[0029] In this embodiment, a plurality of heat-conducting plates 14 are also formed circumferentially at intervals on the inner sidewall of the heat dissipation pipe body 1. Each heat-conducting plate 14 extends from the inner wall of the heat dissipation pipe body 1 along the center of the heat dissipation pipe body 1. By setting a plurality of heat-conducting plates, the contact area between the heat dissipation pipe body and the flue gas flowing through the heat dissipation pipe body can be further increased, thereby further improving the heat exchange efficiency between the heat dissipation pipe body and the flue gas, and thus enabling the heat dissipation pipe body to reliably absorb the heat in the flue gas and radiate the heat outward.

[0030] In this embodiment, a plurality of heat-conducting plates 14 are evenly distributed along the circumferential direction of the heat dissipation pipe body 1, with a portion of the heat-conducting plates 14 located in the first channel 12 and the remaining portion of the heat-conducting plates 14 located in the second channel 13. By adopting this structure, the plurality of heat-conducting plates can simultaneously absorb the heat of the flue gas flowing through the first channel and the second channel, thereby enabling the heat-conducting plates to absorb the heat in the flue gas more reliably and evenly and radiate the heat outward. The aforementioned heat-conducting plates are integrally formed on the inner wall of the heat dissipation pipe body.

[0031] Each heat-conducting fin 14 has an expansion portion 141 at its inner end. The two sides of the expansion portion 141 extend along the circumferential direction of the heat dissipation pipe body 1. With this structure, the contact area between the heat-conducting fin and the flue gas flowing through the first and second channels can be further increased under the action of the expansion portion. This allows the heat-conducting fin to absorb heat from the flue gas more reliably and evenly and radiate the heat outward. The expansion portion is integrally formed on the inner end of the heat-conducting fin.

[0032] See Figure 1-4 As shown, a fuel-fired heater includes a housing 2, a front-opening heat radiation cavity 21 on the housing 2, a protective net 3 fixed at the front opening of the heat radiation cavity 21, a burner 4 fixed inside the heat radiation cavity 21, and an exhaust pipe 5 fixed on the outer top of the housing 2. The fuel-fired heater also includes the aforementioned heat dissipation pipes, with several heat dissipation pipes fixed parallel and at intervals in the heat radiation cavity 21. The several heat dissipation pipes are connected end to end in sequence through a first connecting pipe 6. The first end of the first heat dissipation pipe is connected to the exhaust port of the burner, and the last end of the heat dissipation pipe is connected to the exhaust pipe 5. By adopting this structure, several heat dissipation pipes can be reliably connected end to end through the first connecting pipe, and because the several heat dissipation pipes are fixed parallel and at intervals in the heat radiation cavity, the uniformity of heat radiation from the heat dissipation pipes to the outside through the heat radiation cavity can be improved.

[0033] In this embodiment, several heat dissipation pipes are fixed at equal intervals in the heat radiation cavity 21. The first end of the first heat dissipation pipe is connected to the exhaust port of the burner through the second connecting pipe 7, and the last end of the heat dissipation pipe is connected to the exhaust pipe 5 through the third connecting pipe 8. Each heat dissipation pipe is pressed tightly against the rear side wall of the heat radiation cavity 21 by at least one clamp 9. With this structure, the first end of the first heat dissipation pipe can be reliably connected to the exhaust port of the burner through the second connecting pipe, and the last end of the heat dissipation pipe can be reliably connected to the exhaust pipe through the third connecting pipe. Since several heat dissipation pipes are fixed at equal intervals in the heat radiation cavity, the uniformity of heat radiation from the heat dissipation pipes to the outside through the heat radiation cavity can be further improved. In addition, under the action of the clamps, the heat dissipation pipes can be reliably pressed and fixed in the heat radiation cavity.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
