[0028] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-3 As shown, the embodiment of the utility model provides an energy storage type built-in circulation channel electromagnetic heating device, including an electromagnetic induction control component and an electromagnetic heating body component, the electromagnetic heating body component includes a liquid inlet central tube 1, an outer support plate 3, an inner circulation reciprocating channel body 4, a plurality of inner circulation channels 9 and a liquid outlet pipe 18;

[0034] By utilizing the inner circulation channel 9, the medium is made to flow back and forth in the inner circulation reciprocating channel body 4, so as to increase the heat exchange stroke of the medium.

[0035] In one embodiment, one end of the liquid inlet center tube 1 is fixedly connected to a center tube sealing flange 12, and the center tube sealing flange 12 is flange-connected to the inner side wall of the inner circulation reciprocating channel body 4, and a branch liquid inlet 13 is evenly opened on one side of the inner side wall of the inner circulation reciprocating channel body 4, and a branch liquid outlet 14 is evenly opened on one side of the inner side wall of the inner circulation reciprocating channel body 4. A partition plate 20 is fixedly connected to one side of the inner side wall of the inner circulation reciprocating channel body 4, and an outlet liquid confluence cavity 19 is provided between the partition plate 20 and the liquid outlet pipe 18, and a branch liquid confluence port 16 is evenly opened on the outer side wall of the liquid outlet pipe 18, one end of a plurality of electric valves 15 are connected to the branch liquid outlet 14, and the other end of a plurality of electric valves 15 are connected to the branch liquid confluence port 16.

[0037] In one embodiment, an inner heat insulation layer 10 is fixedly connected between the outer wall of the liquid inlet central tube 1 and the inner wall of the inner circulation reciprocating channel body 4, and a central tube bracket 5 is fixedly connected to one side of the inner wall of the inner circulation reciprocating channel body 4;

[0038] The inner heat-insulating layer 10 is used to provide heat-insulating protection between the liquid inlet central tube 1 and the inner circulation reciprocating channel body 4, and the inner circulation reciprocating channel body 4 and the liquid inlet central tube 1 are supported by a central tube support 5.

[0039] In one embodiment, a front protective cover 26 is installed on one side of the outer support plate 3, the outer wall of the liquid inlet center tube 1 is fixedly connected to the inner wall of the front protective cover 26, the other side of the outer support plate 3 is fixedly connected to the rear protective cover 22, the outer wall of the liquid outlet pipe 18 is fixedly connected to the inner wall of the rear protective cover 22, and the front protective cover 26, the rear protective cover 22 and the outer support plate 3 are filled with insulating material 23.

[0040] The outer support plate 3 is insulated and heat-insulated by using the insulating and heat-preserving material 23 .

[0041] In one embodiment, the outer wall of the outer support plate 3 is covered with an electromagnetic coil protection insulation plate 6, the outer wall of the electromagnetic coil protection insulation plate 6 is covered with an anti-corrosion and thermal insulation layer 7, a heat medium 11 flows inside the liquid inlet central tube 1, and the bottom of the outer wall of the outer support plate 3 is fixedly connected to an equipment base 25.

[0042] The electromagnetic induction coil 8 is insulated and protected by the electromagnetic coil protection insulating plate 6 , and the external support plate 3 and the electromagnetic coil protection insulating plate 6 are insulated by the anti-corrosion and thermal insulation layer 7 .

[0043] In one embodiment, the inner circulation reciprocating channel body 4 is divided into three circulation areas as an example. Figure 3 As shown, D is the outer diameter of the inner circulation reciprocating channel body 4, d is the inner diameter, and the length of the inner circulation reciprocating channel body 4 is L. After the heating medium 11 is introduced, it is circulated and heated in the reciprocating circulation channel in a high temperature environment, so that the heating distance of the medium in each area of ​​the heating device reaches several times the length of the heater body. The heating medium 11 obtains more heat exchange time and heat exchange area, thereby improving the heating efficiency. The specific heating effect is as follows Figure 2 shown.

[0044] When the utility model is working: the electromagnetic induction coil 8 is started to heat the inner circulation reciprocating channel body 4 as a whole, and then the heat medium 11 to be heated is injected into the inner circulation reciprocating channel body 4 through the liquid inlet center tube 1, and then the heat medium 11 is introduced into the inner circulation channel 9 through the branch liquid inlet 13, and then the heat medium 11 is made to reciprocate inside the inner circulation reciprocating channel body 4 through the inner circulation channel 9, so as to make full use of the space in the inner circulation reciprocating channel body 4 to increase the heat exchange stroke of the heat medium 11, and then the heated heat medium 11 is introduced into the outlet liquid confluence cavity 19 of the liquid outlet pipe 18 through the branch liquid outlet 14 in cooperation with the electric valve 15 and the branch liquid confluence port 16, so as to mix the heated heat medium 11 and discharge it uniformly through the liquid outlet pipe 18.

[0046] When the data detected by the inlet temperature sensor 2 and the outlet temperature sensor 17 are both lower than the threshold value, the controller 27 uses the relay to start the electromagnetic induction coil 8, and the working electromagnetic induction coil 8 heats the inner circulation reciprocating channel body 4 as a whole, and controls the electric valve 15 through the controller 27 to reduce the amount of the heated medium 11 flowing out of the inner circulation channel 9, so as to reduce the flow speed of the heated medium 11 in the inner circulation channel 9, increase its heat exchange time, and avoid insufficient heating of the heated medium 11.

[0047] When the data detected by the inlet temperature sensor 2 is lower than the threshold value, and the data detected by the outlet temperature sensor 17 is within the threshold range, the electric valve 15 is controlled by the controller 27 to restore the amount of the heat medium 11 flowing out of the inner circulation channel 9 to normal, so that the heat medium 11 moves at a normal flow rate in the inner circulation channel 9 to ensure the heating efficiency.

[0048] When the data detected by the inlet temperature sensor 2 is lower than the threshold value, and the data detected by the outlet temperature sensor 17 is higher than the threshold value, the electromagnetic induction coil 8 is closed by means of a relay through the controller 27, and the electric valve 15 is controlled to be fully opened, thereby increasing the flow speed of the heated medium 11 in the inner circulation channel 9 to reduce its heat exchange time and prevent the heating temperature from being too high.

[0049] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
