[0048] Embodiment 2

[0049] Reference Figures 1 to 6, the heating pipeline structure of the cogeneration unit of the present invention includes a heating plate body 1, a diversion heating component arranged on the heating plate body 1. The heat gathered by the diversion heating component is transferred to the top of the enhanced heat conduction cover 6, heating the top of the enhanced heat conduction cover 6, and then heat conduction and dissipation are carried out through the enhanced heat conduction cover 6 to distribute the heat in the medium in the heat exchange cavity, thereby heating the medium in the heat exchange cavity. At the same time, the heat-insulating sleeve body 2 is used to insulate the heated medium in the heat exchange cavity, reducing the heat loss rate. The heated medium in the heat exchange cavity is transported to the gathering discharge box 12 through the enhanced medium delivery pipe 10 and discharged after being gathered by the gathering discharge box 12. At the same time, the flow rate of the medium transported to the enhanced medium delivery pipe 10 is adjusted by the regulating valve 9. When the medium is transported into the device for heat exchange and heat supply, the excess medium is discharged through the second drain vertical pipe 17 and the first drain vertical pipe 16, which is convenient for the staff to install a conduit at the end of the first drain vertical pipe 16 and convenient for the medium to be collected after passing through the device for heat exchange, avoiding poor heat exchange effect caused by excessive medium flow rate. And the specific structure of the components is as follows;

[0050] The diversion heating component includes a heat-insulating sleeve body 2 sleeved outside the heating plate body 1. A strengthened partition board 3 is fixedly arranged at the top of the heat-insulating sleeve body 2. A heat exchange cavity is arranged between the heat-insulating sleeve body 2 and the strengthened partition board 3. A number of heat-conducting copper plates 19 are distributed on the outside of the heat-insulating sleeve body 2.

[0051] A number of diversion holes 4 are opened at the top of the strengthened partition board 3, and a diversion triangular frame 5 for diversion is embedded in each diversion hole 4. A filter element 18 is arranged in the diversion triangular frame 5.

[0052] The enhanced heat conduction cover 6 is embedded in the middle of the heating plate body 1. An insulation chamber 13 is opened on the enhanced heat conduction cover 6. A heating wire 7 is arranged at the bottom of the inner wall of the insulation chamber 13. A number of one-way valves 8 are embedded on the outside of the heat-insulating sleeve body 2, and each one-way valve 8 is communicated with the heat exchange cavity. A regulating valve 9 is threadedly connected to the one-way valve 8. A strengthened medium delivery pipe 10 is threadedly connected to the regulating valve 9, and each strengthened medium delivery pipe 10 is communicated with the gathering discharge box 12. The gathering discharge box 12 is communicated with the strengthened medium delivery pipe 10. A strengthened bottom plate 11 is arranged at the top of the gathering discharge box 12. The strengthened bottom plate 11 is located at the bottom of the enhanced heat conduction cover 6, and a sealing gasket is arranged between the gathering discharge box 12 and the enhanced heat conduction cover 6.

[0053] A limiting gasket ring 14 is sleeved outside the enhanced heat conduction cover 6. The limiting gasket ring 14 is located between the heating plate body 1 and the limiting sleeve body 2, and both the limiting sleeve body 2 and the heating plate body 1 are detachably connected to the limiting gasket ring 14 through bolts. A reinforcing vertical pipe 15 is sleeved outside the shunt triangular frame 5, and the reinforcing vertical pipe 15 is fixed to the top of the reinforcing partition plate 3. A first drainage vertical pipe 16 is fixedly arranged in the middle of the enhanced heat conduction cover 6, and a second drainage vertical pipe 17 is fixedly arranged in the middle of the heating plate body 1. The second drainage vertical pipe 17 and the first drainage vertical pipe 16 are stacked, and the second drainage vertical pipe 17 extends to the top of the first drainage vertical pipe 16.

[0054] During use according to the above structure, the staff installs the device at a designated position. When heating, the medium is gathered through the reinforcing vertical pipe 15, and the medium is shunted through each shunt triangular frame 5. Moreover, the filter element 18 embedded in the shunt triangular frame 5 filters the medium shunted by the shunt triangular frame 5 to prevent impurities in the medium from blocking the device.

[0055] When the medium is transported to the heat exchange cavity, it is heated by the heating wire 7. After the heat is gathered by the enhanced heat conduction cover 6, the heat is transferred to the top of the enhanced heat conduction cover 6, heating the top of the enhanced heat conduction cover 6 and dissipating heat through heat conduction by the enhanced heat conduction cover 6, distributing the heat in the medium in the heat exchange cavity, thereby heating the medium in the heat exchange cavity. At the same time, the limiting sleeve body 2 insulates the heated medium in the heat exchange cavity, reducing the heat loss rate.

[0056] The heated medium in the heat exchange cavity is transported to the gathering discharge box 12 through the enhanced medium conveying pipe 10 and discharged after being gathered by the gathering discharge box 12. At the same time, the flow rate of the medium transported to the enhanced medium conveying pipe 10 is adjusted through the regulating valve 9. Moreover, when the medium is transported into the device for heat exchange and then used for heating, the excess medium is discharged through the second drainage vertical pipe 17 and the first drainage vertical pipe 16, making it easy for the staff to install a conduit at the end of the first drainage vertical pipe 16, facilitating the collection of the medium after passing through the device for heat exchange, and preventing poor heat exchange caused by excessive medium flow rate.

[0057] Different from the prior art, the present application discloses a heating pipeline structure of a cogeneration unit. After the heat is gathered, it is transferred to the top of the enhanced heat conduction cover 6, so that the top of the enhanced heat conduction cover 6 is heated and heat conduction and heat dissipation are carried out through the enhanced heat conduction cover 6, and the heat is distributed in the medium in the heat exchange cavity, and then the medium in the heat exchange cavity can be heated. At the same time, the temperature of the heated medium in the heat exchange cavity is insulated by the limiting sleeve body 2 to reduce the heat loss rate. The heated medium in the heat exchange cavity is transported to the gathering discharge box 12 through the enhanced medium delivery pipe 10 and discharged after being gathered by the gathering discharge box 12. At the same time, the flow rate of the medium transported to the enhanced medium delivery pipe 10 is adjusted by the regulating valve 9. When the medium is transported into the device for heat exchange and heat supply, the excess medium is discharged through the second drain vertical pipe 17 and the first drain vertical pipe 16, which is convenient for the staff to install a conduit at the end of the first drain vertical pipe 16 and convenient for the medium to be collected after passing through the device for heat exchange, avoiding poor heat exchange effect caused by too large medium flow rate.
