Embodiment 1
[0028] Embodiment 1: a kind of electric heating heat storage heat exchanger, such as Figures 1 to 6 shown. The device includes a housing 5, which is in the shape of a pot with an upper opening, and the upper opening is sealed with a cover plate 7 that can be hoisted and disassembled. The heat storage medium 11 is filled in the casing, and the heat storage medium is a medium capable of phase-change heat storage. Four filling ports c are arranged on the circumference of the upper end of the casing, and a heat storage medium discharge port is arranged at the bottom end of the casing. The shell is provided with a heat exchange pipe 2, such as figure 1 , 2 As shown in , the heat exchange pipe turns back up and down in the vertical plane and coils in a serpentine manner, as shown in Figure 4 As shown in the figure, the heat exchange pipes are arranged in a meandering way back and forth on the horizontal plane, covering the interior of the shell. Such as figure 2 , 6 As sho...
Embodiment 2
[0031] Embodiment 2: An electric heating heat storage heat exchanger in which the distribution density of the heat exchange pipes is designed according to the position of the inlet and outlet of the heat exchange pipes, such as Figure 1 to Figure 3 , Figures 7 to 9 shown. The device includes a housing 5, which is in the shape of a pot with an upper opening, and the upper opening is sealed with a cover plate 7 that can be hoisted and disassembled. The heat storage medium 11 is filled in the casing, and the heat storage medium is a medium capable of phase-change heat storage. Four filling ports c are arranged on the circumference of the upper end of the casing, and a heat storage medium discharge port is arranged at the bottom end of the casing. The shell is provided with a heat exchange pipe 2, such as figure 1 , 2 As shown in , the heat exchange pipe turns back up and down in the vertical plane and coils in a serpentine manner, as shown in Figure 7 As shown, the heat exc...
