Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to a temperature difference power generation device used in a heating device. Background Art

[0002] Currently, due to technical limitations, existing processing chips generate a lot of heat when working, and need to be equipped with a heat sink to actively dissipate heat for the chip. Most of the heat sinks on the market directly dissipate the heat, and do not use the generated heat, resulting in energy loss.

[0003] A thermoelectric generator is disclosed in Chinese patent CN201510099016.7, including multiple cooling channels, heat flow channels, multiple heat conducting plates and multiple thermoelectric generating elements. The heat conducting plates pass through the heat flow channels to separate them longitudinally. The heat conducting plates located in the heat flow channels are inner fins, and the heat conducting plates located outside the heat flow channels are outer fins. The cooling channels are arranged between every two outer fins. The thermoelectric generating elements are arranged between the outer fins and the cooling channels. After the multiple thermoelectric generating elements are electrically connected, the positive and negative electrodes are led out through wires. The thermoelectric generating function is realized by arranging the heat flow channels and the cooling channels for the heat source to pass through in a three-dimensional manner, and enabling the thermoelectric generating elements to contact the heat flow channels and the cooling channels at the same time and be located on different sides of the thermoelectric generating elements.

[0004] However, the above-mentioned equipment is specially equipped with a heat source for generating electricity and cannot generate electricity using the heat generated by ordinary equipment during operation.

[0005] Therefore, it is necessary to design a device that can utilize the heat emitted by the device to generate electricity. Utility Model Content

[0016] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0017] like Figure 1 to Figure 2As shown, it is a schematic diagram of the structure of a thermoelectric power generation device for a heating device provided by the utility model. The thermoelectric power generation device for a heating device includes a heat dissipation device 10, and a thermoelectric power generation device 20 arranged on one side of the heat dissipation device 10. It can be imagined that the thermoelectric power generation device for a heating device also includes some other functional structures, such as a condenser, etc., which are well known to those skilled in the art and will not be described in detail here.

[0018] The heat dissipation device 10 includes a heat dissipation fin unit 11 , a heat dissipation fan 12 disposed on a side of the heat dissipation fin unit 11 having a gap, and a heat conduction portion 13 inserted on the heat dissipation fin unit 11 .

[0019] The heat dissipation fin unit 11 is made of a plurality of aluminum sheets stacked together, so that the heat is transmitted through the heat dissipation fin unit 11 to improve the heat dissipation effect. The heat dissipation fin unit 11 is a prior art and will not be described in detail herein.

[0020] The heat dissipation fan 12 is screwed to the heat dissipation fin unit 11. The blowing surface of the heat dissipation fan 12 is arranged toward the heat dissipation fin unit 11, so that the heat dissipation fin unit 11 is further radiated by the heat dissipation fan 12 to improve the heat dissipation efficiency of the heat dissipation fin unit 11. The heat dissipation fan 12 is an existing technology on the market, and the heat dissipation fan 12 is an existing technology and will not be described in detail here.

[0021] The heat conducting part 13 includes two heat conducting pipes 14 inserted in the heat dissipation fin unit 11 , and a heat conducting seat 15 disposed at one end of the two heat conducting pipes 14 .

[0022] The two heat-conducting pipes 14 are inserted into the heat-dissipating fin unit 11 at intervals. The length of the heat-conducting pipe 14 is greater than the height of the heat-dissipating fin unit 11, so that the heat-dissipating fin unit 11 as a whole can help the heat-conducting pipe 14 to dissipate heat. A heat-conducting medium is poured into the heat-conducting pipe 14 to improve the thermal conductivity. The end of the heat-conducting pipe 14 away from the heat-conducting seat 15 is closed. The heat-conducting seat 15 abuts against one side of the temperature difference power generation device 20, and the heat-conducting seat 15 is used to connect the temperature difference power generation device 20 to dissipate heat from the side wall of one side of the temperature difference power generation device 20.

[0023] The temperature difference power generation device 20 includes a heat conducting head 21 , a fixing plate 22 disposed on the heat conducting head 21 and connected to the heat conducting seat 15 , and a temperature difference power generation plate 23 embedded in the fixing plate 22 .

[0024] The outer contour of the heat conducting head 21 is circular, which increases the contact area and improves the heat conduction effect. The area of ​​the heat conducting head 21 is larger than the area of ​​the heat conducting seat 15, so that the heat transferred by the heat conducting head 21 is greater than the heat transferred by the heat conducting seat 15, forming a temperature difference.

[0025] The fixing plate 22 and the heat conducting head 21 are connected together by screwing. A mounting groove for embedding the temperature difference power generation plate 23 is reserved in the fixing plate 22.

[0026] The thermoelectric power generation sheet 23 is embedded in the fixing sheet 22. One end face of the thermoelectric power generation sheet 23 is in conflict with the heat-conducting seat 15, and the other end face is in conflict with the heat-conducting head 21. The thermoelectric power generation sheet 23 is connected to the external device by wiring. The working principle of the thermoelectric power generation sheet 23 is based on the Seebeck effect, that is, when there is a temperature difference in a closed loop composed of two different conductors or semiconductor materials, an electromotive force will be generated at both ends. The thermoelectric power generation sheet is usually composed of strips of two different materials arranged alternately, the hot end is connected to the heat source, and the cold end is connected to the radiator or cooling system. The thermoelectric power generation sheet 23 is an existing technology on the market and will not be described here.

[0027] When in use, the device is pressed onto the heat source so that the thermal head 21 is pressed onto the heat source. The thermal head 21 absorbs and transfers heat to the thermoelectric power generation sheet 23. The thermoelectric power generation sheet 23 transfers the absorbed heat to the heat conducting part 13, and dissipates the heat into the air through the heat dissipation fin unit 11. The cooling fan 12 blows air toward the heat dissipation fin unit 11 to help the heat dissipation fin unit 11 dissipate heat, so that the temperature of the thermal seat 15 is always lower than the temperature of the thermal head 21, maintaining the temperature difference so that the thermoelectric power generation sheet 23 generates electricity. Dissipating heat from the heat dissipation fin unit 11 by the cooling fan 12 is a common method for air-cooled radiators on the market, that is, the temperature difference between the thermal head 21 and the thermal seat 15 is always maintained during use. Therefore, the electricity generated by the thermoelectric power generation sheet 23 is all generated by utilizing excess heat, and there is no need to set up an additional cooling fan for cooling for power generation.

[0028] Compared with the prior art, the utility model provides a thermoelectric power generation device for use in a heating device by providing the heat dissipation device 10 and a thermoelectric power generation device 20 provided on one side of the heat dissipation device 10. The heat dissipation device 10 includes a heat dissipation fin unit 11, a heat dissipation fan 12 provided on one side of the heat dissipation fin unit 11 having a gap, and a heat conduction portion 13 inserted on the heat dissipation fin unit 11. The thermoelectric power generation device 20 includes a heat conduction head 21, a fixing plate 22 provided on the heat conduction head 21, and a thermoelectric power generation plate 23 embedded in the fixing plate 22. During use, one end face of the temperature difference power generation sheet 23 contacts the heat conductive seat 15, and the other end face contacts the heat conductive head 21. Heat is transferred to one side of the temperature difference power generation sheet 23 through the heat conductive head 21, and the other side of the temperature difference power generation sheet 23 is cooled through the heat conductive seat 15 in the heat dissipation fin unit 11. The heat dissipation fan 12 actively dissipates the heat dissipation fin unit 11, so that there is a temperature difference between the two sides of the temperature difference power generation sheet 23, so that the temperature difference power generation sheet 23 is continuously used to generate electricity, thereby improving energy utilization.
