For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0037] Embodiment 1:
[0038] See also Figure 1 As shown, this embodiment proposes a furnace for heating phase change materials, including a furnace body 1, a plurality of shock-absorbing bases 2 are fixedly installed at the bottom of the furnace body 1, and a closing cover 3 is fixedly installed at the top of the furnace body 1 to prevent heat loss while facilitating material loading.
[0039] like Figure 3 and 4 As shown, the furnace also includes a preheating component 4. Specifically, the preheating component 4 includes a heat conducting plate 41, a heating rod 43 and a preheating pipe 44. The heat conducting plate 41 is fixedly installed on the inner wall of the furnace body 1. The heating rod 43 is fixedly installed between the heat conducting plate 41 and the furnace body 1. The preheating pipe 44 is fixedly installed on the top of the heat conducting plate 41. Phase change material flows in the preheating pipe 44. The heating rod 43 transfers heat to the preheating pipe 44 through the heat conducting plate 41. The temperature transferred to the preheating pipe 44 is reduced by the heat conducting plate 41 to avoid direct contact between the heating rod 43 and the preheating pipe 44, which causes the phase change material in the preheating pipe 44 to heat up too quickly and lose its performance.
[0040] Among them, Figure 2 and 3As shown, the heat conducting plate 41 adopts a hollow truncated cone structure, the preheating pipe 44 adopts a mosquito coil-like structure, and the center thereof protrudes upward, the preheating pipe 44 is attached to the heat conducting plate 41, and the preheating pipe 44 is divided into multiple sections, each section has a different heat conducting medium, and the heat conducting capacity of the preheating pipe 44 gradually increases from the inner circle to the outer circle. In this embodiment, the preheating pipe 44 is divided into three spiral sections, each section has a different heat conducting medium, and the preheating pipe 44 is from the inner circle to the outer circle. The first spiral section adopts an alumina tube, The second spiral section adopts aluminum nitride tube, and the third spiral section adopts silicon carbide tube, whose thermal conductivity is gradually enhanced. Therefore, the temperature of the preheating pipe 44 gradually increases from the inner circle to the outer circle, that is, when the phase change material enters from the end of the inner circle of the preheating pipe 44, the temperature it is subjected to is low. With the continuous addition of phase change material at the end of the inner circle of the preheating pipe 44, the phase change material flows inside the preheating pipe 44 and is preheated through the preheating pipe 44. At the same time, different media are used to achieve different temperatures in multiple sections to control the heating speed.
[0041] In this embodiment, a heating bin 42 is fixedly installed on the inner wall of the furnace body 1 and below the heat conducting plate 41, and the end of the preheating pipe 44 located at the outer circle penetrates into the interior of the heat conducting plate 41, and the heat conducting plate 41 and the heating bin 42 are connected to each other. A material adding pipe 45 is fixedly installed at the end of the preheating pipe 44 located at the inner circle, and the material adding pipe 45 penetrates the closing cover 3. The phase change material enters from the material adding pipe 45 and flows along the preheating pipe 44 into the interior of the heating bin 42.
[0042] like Figure 3 As shown, the top of the closing cover 3 is fixedly threaded with an insulation cover 46 located at the material adding pipe 45. By opening the insulation cover 46, the phase change material is heated from the material adding pipe 45 into the heating chamber 42, and the closing cover 3 insulates the heating chamber 42 to prevent heat loss.
[0043] Furthermore, heating rods 43 are fixedly installed at the bottom and around the heating chamber 42, and the phase change material entering the heating chamber 42 is heated by the heating rods 43. When the heating rods 43 and the preheating pipe 44 cooperate to preheat the added phase change material, the heating rods 43 also heat the heating chamber 42, and the phase change material is heated by the preheating pipe 44 so that the phase change material has a certain temperature after entering the heating chamber 42, thereby avoiding excessive temperature difference between the heating chamber 42 and the phase change temperature.
[0044] Furthermore, the preheating pipe 44 prolongs the path of the phase change material entering the heating chamber 42, thereby increasing the time for the phase change material to enter the heating chamber 42, improving the preheating effect of the phase change material, and in this process, the heating chamber 42 is heated to the set temperature, saving heating time and improving heating efficiency.
[0045] In this embodiment, heat is transferred to the preheating pipe 44 through the heating rod 43, so that the preheating pipe 44 preheats the phase change material flowing therein, and because the preheating pipe 44 is divided into multiple sections, each section has a different heat transfer medium, and the temperature of the preheating pipe 44 gradually increases from the inner circle to the outer circle, so that the phase change material can be progressively heated during preheating, thereby avoiding a large temperature difference between the heating temperature of the phase change material and the heating rod 43 after the phase change material enters the heating chamber 42, resulting in excessive heating speed and causing the phase change material to lose its performance.
[0046] Embodiment 2:
[0047] like Figure 3 As shown, based on the first embodiment, this embodiment proposes a furnace for heating phase change materials, wherein a mixing assembly 5 is arranged inside the furnace body 1, and the mixing assembly 5 comprises a stirring shaft 51, stirring blades 52 and a motor 53, wherein the end of the stirring shaft 51 passes through the heating bin 42 and is rotatably connected to the furnace body 1, and the stirring blades 52 are fixedly installed at the shaft of the stirring shaft 51, and the motor 53 is fixedly installed at the end of the stirring shaft 51, and the motor 53 is fixedly installed inside the closing cover 3. The stirring blades 52 are driven to rotate by the stirring shaft 51 to stir the phase change material in the heating bin 42.
[0048] A plurality of stirring blades 52 are provided, and the plurality of stirring blades 52 are distributed in a straight line and equidistantly along the stirring shaft 51 , and the stirring blades 52 are in contact with the phase change material inside the heating chamber 42 , thereby increasing the stirring area of the stirring blades 52 .
[0049] In this embodiment, the phase change material in the heating chamber 42 is stirred by rotating the stirring blades 52, so that the phase change material in the heating chamber 42 is heated evenly while avoiding local heating. The design of multiple stirring blades 52 increases the stirring area of the stirring blades 52.
[0050] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
