Technical Field

[0001] This utility model relates to an explosion-proof heater with good thermal conductivity. Background Technology

[0002] Explosion-proof heaters are heating devices specifically designed for environments containing flammable and explosive media, and are widely used in industries such as chemical, petroleum, and natural gas. Their core function is to raise the temperature of the medium through heating elements while ensuring safety.

[0003] Existing explosion-proof heaters suffer from problems such as concentrated heat in the central heating tube and insufficient temperature in the edge areas, resulting in uneven heating of the medium and even safety hazards due to local overheating. Utility Model Content

[0004] The main objective of this invention is to provide an explosion-proof heater with good thermal conductivity to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] An explosion-proof heater with good thermal conductivity includes an explosion-proof junction box, a heating cylinder, and multiple heating tubes. Multiple heat-conducting plates are arranged on the outer side of the outer wall of the heating tubes. The multiple heat-conducting plates are spaced apart along the length of the heating tubes. The heat-conducting plates extend outward and are connected to the inner wall of the heating cylinder. Spiral guide vanes are arranged inside the heating cylinder along its length.

[0007] Preferably, the heat-conducting plate has an arc-shaped structure and its outer edge is bent downwards.

[0008] Preferably, the heat-conducting plates on different heating tubes are arranged at intervals along the circumference of the heating cylinder, and the heat-conducting plates are staggered at different length positions of the heating tubes.

[0009] Preferably, the two ends of the spiral guide vane are fixed to the bottom of the explosion-proof junction box and the bottom surface of the inner wall of the heating cylinder, respectively.

[0010] Preferably, four spiral guide vanes are spaced apart, and each spiral guide vane is disposed in the gap between two adjacent heat-conducting plates.

[0011] Preferably, a reinforcing ring is provided on the heat-conducting plate at the same length position on different heating tubes.

[0012] Preferably, a spiral water-cooling pipe is provided on the outer wall of the heating cylinder.

[0013] The beneficial technical effects of this utility model are as follows:

[0014] The heat-conducting plate provided by this invention can quickly guide the heat from the center of the heating tube to the edge of the heating cylinder, ensuring a uniform temperature distribution throughout the heating cylinder and significantly increasing the effective heat-conducting area, forming an efficient heat path and achieving excellent heat conduction. The spiral guide vanes lengthen the flow path of the fluid within the heating cylinder, increasing the contact time between the fluid and the heating tube and heat-conducting plate, thus improving the heating effect.

[0021] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0022] like Figures 1-5 As shown, the explosion-proof heater with good thermal conductivity provided in this embodiment includes an explosion-proof junction box 1, a heating cylinder 2 and multiple heating tubes 3. Multiple heat-conducting plates 4 are provided on the outer side of the outer wall of the heating tube 3. The multiple heat-conducting plates 4 are spaced apart along the length direction of the heating tube 3. The heat-conducting plates 4 extend outward and are connected to the inner wall of the heating cylinder 2. Spiral guide vanes 5 are provided inside the heating cylinder 2 along its length direction.

[0023] The heat-conducting plate 4 can quickly guide the heat from the center of the heating tube 3 to the edge of the heating cylinder 2, ensuring a uniform temperature distribution throughout the heating cylinder 2 and significantly increasing the effective heat conduction area, forming an efficient heat path and achieving good heat conduction. The spiral guide vane 5 lengthens the flow path of the fluid within the heating cylinder 2, increasing the contact time between the fluid and the heating tube 3 and the heat-conducting plate 4, thus improving the heating effect.

[0024] In this embodiment, as Figure 1 As shown, the heat-conducting plate 4 has an arc-shaped structure with its outer edge bent downwards to form a flow-guiding structure, which further optimizes the liquid flow path and increases the heat exchange area, thereby further improving the heat conduction effect.

[0025] In this embodiment, as Figure 1 As shown, heat-conducting plates 4 are arranged at intervals along the circumference of the heating cylinder 2 on different heating tubes 3. The heat-conducting plates 4 are staggered at different length positions of the heating tubes 3. The staggered layout forces the medium to change its path multiple times during the flow process, increasing the contact frequency with the heat-conducting plates 4 and enhancing the heat exchange effect.

[0026] In this embodiment, as Figure 5 As shown, the two ends of the spiral guide vane 5 are fixed to the bottom of the explosion-proof junction box 1 and the bottom surface of the inner wall of the heating cylinder 2, respectively, to ensure the structural stability of the spiral guide vane 5.

[0027] In this embodiment, as Figure 1 As shown, four spiral guide vanes 5 are spaced apart, dividing the cross-section of the heating cylinder 2 into multiple vortex regions, enhancing turbulence intensity and improving the convective heat transfer coefficient. Each spiral guide vane 5 is set in the gap between two adjacent heat conduction plates 4, without affecting the heat conduction path of the heat conduction plate 4. At the same time, the gap space is used to form a spiral flow channel, realizing the synergistic optimization of heat conduction and flow guidance.

[0028] In this embodiment, as Figure 1 As shown, reinforcing rings 6 are provided on the heat-conducting plates 4 at the same length position on different heating tubes 3. The reinforcing rings 6 are connected in series with the heat-conducting plates 4 on different heating tubes 3 to form an overall support structure to resist internal pressure or external impact and prevent the heat-conducting plates 4 from deforming.

[0029] In this embodiment, as Figure 3 As shown, a spiral water-cooling pipe 7 is provided on the outer wall of the heating cylinder 2. A water pump is connected to the spiral water-cooling pipe 7 to introduce cooling water into the spiral water-cooling pipe 7, so as to dissipate excess heat on the heating cylinder 2 in time and prevent heat from accumulating on the heating cylinder 2.

[0030] In summary, in this embodiment, the heat-conducting plate 4 can quickly guide the heat from the center of the heating tube 3 to the edge of the heating cylinder 2, ensuring a uniform temperature distribution throughout the heating cylinder 2, and significantly increasing the effective heat conduction area to form a highly efficient heat path and achieve a good heat conduction effect. The spiral guide vane 5 lengthens the flow path of the fluid within the heating cylinder 2, increasing the contact time between the fluid and the heating tube 3 and the heat-conducting plate 4, thereby improving the heating effect.

[0031] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
