[0031] Implementation

[0032] Please see Figure 1 -4. A waste heat recovery device for a spiral heat exchanger, comprising:

[0033] Box 1;

[0034] The inner box 5 and the partition 18 for supporting the inner box 5 are arranged inside the box body 1.

[0035] The inner box 5 is equipped with heat-conducting fins 8, which are used to divide the inner box 5 into a high-temperature chamber 9 and a conductive chamber 10.

[0036] The high-temperature chamber 9 is equipped with a heat dissipation component, and the bottom of the conduction chamber 10 is equipped with a heat recovery component. Heat is conducted between the high-temperature chamber 9 and the conduction chamber 10 through the heat-conducting fin plate 8.

[0037] The recycling assembly includes a conductive plate 11 disposed inside the conductive chamber 10 and a thermoelectric element 12 disposed on the lower surface of the conductive plate 11;

[0038] The inside of the box 1 is through a conveying pipe 2, and the outer wall of the conveying pipe 2 is provided with a recycling pipe 3, which is connected to the conveying pipe 2.

[0039] The recycling assembly also includes a cooling fan 14 located at the bottom of the partition 18 and a heat-conducting plate 13 fixedly connected to the positive electrode surface of the thermoelectric element 12. A ventilation grille 15 is provided at the bottom of the housing 1 to provide sufficient heat dissipation space for the cooling fan 14.

[0040] A storage battery 17 is provided at the bottom of the partition 18, and the storage battery 17 is connected to the recycling component.

[0041] The heat dissipation assembly includes a connector 6 and a spiral tube 7 that are fixedly connected to the recovery tube 3. The spiral tube 7 is fixedly connected to the connector 6, and both ends of the spiral tube 7 are connected to the recovery tube 3 through the connector 6.

[0042] The input end of the conveying pipe 2 is connected to the input end of the recovery pipe 3, and the end of the recovery pipe 3 is connected to the end of the conveying pipe 2. A three-way valve 4 is provided at one end of the recovery pipe 3 to control the connection between the conveying pipe 2 and the recovery pipe 3.

[0043] The inner chamber 5 is provided with a first liquid exchange port 19 and a second liquid exchange port 20 on both sides. The first liquid exchange port 19 is connected to the conduction chamber 10, and the second liquid exchange port 20 is connected to the high temperature chamber 9.

[0044] The technical solution provided in this embodiment is as follows: In use, first connect the device to a heat exchanger. Connect one end of the conveying pipe 2 to an external heat input device and the other end to the heat exchanger input. Then ensure sufficient heat transfer fluid inside the high-temperature chamber 9 and the conduction chamber 10. Afterward, it can be used. During use, by adjusting the single-way valve, the liquid inside the conveying pipe 2 flows through the recovery pipe 3 and then into the spiral tube 7. Inside the spiral tube 7, the contact surface increases, and the temperature inside the spiral tube 7 is conducted to the interior of the high-temperature chamber 9, and then through heat conduction... Fin plate 8 enters conduction chamber 10. When it enters conduction chamber 10, conduction plate 11 conducts heat to thermoelectric element 12, generating electrical energy through thermoelectric effect and transferring the electrical energy to the inside of storage battery 17. When thermoelectric effect is generated, cooling fan 14 starts to cool heat conduction plate 13. Heat conduction plate 13 is in close contact with the positive electrode of thermoelectric element 12 to increase temperature difference and improve the efficiency of thermoelectric effect. After the liquid inside high temperature chamber 9 and conduction chamber 10 has been used for a certain period of time, the liquid is replaced through first liquid replacement port 19 and second liquid replacement port 20 to prevent the internal liquid from deteriorating.

[0045] Furthermore, multiple pads 16 are provided above the partition 18 to support the inner box 5 and prevent the inner box 5 from directly contacting the partition 18 and the box body 1.

[0046] Specifically, by setting the pad 16, the high-temperature inner box 5 can be prevented from directly contacting the box body 1, thus avoiding deformation of the box body 1.

[0047] Furthermore, the spiral tubes 7 are arranged linearly in a vortex pattern and interconnected with each other.

[0048] Specifically, by setting up multiple spiral tubes 7, the heat dissipation efficiency can be further increased and the waste heat recovery efficiency can be improved.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
