Description

Technical Field

[0001] The utility model relates to the technical field of biogas power generation, in particular to a heat dissipation and heat exchange device for a biogas generator set. Background Technique

[0002] As a renewable energy technology, biogas power generation has received extensive attention and promotion globally in recent years. Biogas is produced by the decomposition of organic substances under anaerobic conditions, and its main component is methane, which has a high energy value. Biogas power generation can not only reduce the dependence on fossil fuels, but also effectively solve the problem of organic waste treatment, while reducing greenhouse gas emissions. In the process of using existing biogas generator sets, most of them use circulating water for cooling, but its heat dissipation effect is still limited, which will affect the service life of biogas generator sets. To solve the above defects, the patent document with the publication number of CN215109133U in the prior art provides a heat dissipation and heat exchange device for a biogas generator set. The device is provided with a heat-conducting aluminum plate that fits the generator, so that it can absorb and transfer the heat generated by the motor. Cooperating with the heat-conducting rod, the heat can be conducted to the water tank to improve the heat dissipation effect of the motor.

[0003] However, the heat-conducting aluminum plate provided by this device can only be in contact with the top surface of the generator, which makes the device unable to dissipate heat from the periphery and bottom of the generator, obviously affecting the heat dissipation effect of the generator, and there are relatively large defects. For this reason, we have proposed a heat dissipation and heat exchange device for a biogas generator set. Content of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figure 1-7, the present utility model provides a technical solution: a heat dissipation and heat exchange device for a biogas generator set, including a box body 1. Installation cavities 11 and liquid storage cavities 13 are respectively opened on the upper and lower sides of the inner cavity of the box body 1. A working cavity 12 is opened at the outer end of the box body 1, and the working cavity 12 is arranged between the liquid storage cavity 13 and the installation cavity 11. A heat conduction frame 16 and a generator 17 are fixedly installed in the installation cavity 11 through bolts. The outer rotor of the generator 17 is arranged in the working cavity 12, and the heat conduction frame 16 is arranged outside the generator 17. A liquid outlet pipe 2 and a liquid return pipe 21 communicating with the liquid storage cavity 13 are fixedly installed at the bottom of the installation cavity 11. A first heat dissipation pipe 22 corresponding to the generator 17 is fixedly installed in the installation cavity 11. The two ends of the periphery of the first heat dissipation pipe 22 are respectively connected to the liquid outlet pipe 2 and the liquid return pipe 21. A second heat dissipation pipe 23 and a third heat dissipation pipe 24 which are communicated with each other are respectively fixedly installed on the periphery and the top of the inner cavity of the heat conduction frame 16. The two ends of the head and the tail of the second heat dissipation pipe 23 are respectively inserted into the two ends of the head and the tail of the first heat dissipation pipe 22.

[0028] Working principle: When in use, according to the biogas volume, power generation demand and operation cost, the number of generators 17 can be adjusted in the installation cavity 11, and then the heat conduction frame 16 is installed outside the generator 17, and the second heat dissipation pipe 23 is communicated with the first heat dissipation pipe 22 to complete the installation of the generator 17;

[0029] Through the liquid outlet pipe 2 and the liquid return pipe 21, the coolant can be circulated and guided in the liquid storage cavity 13, the first heat dissipation pipe 22, the second heat dissipation pipe 23 and the third heat dissipation pipe 24. The first heat dissipation pipe 22, the second heat dissipation pipe 23 and the third heat dissipation pipe 24 are respectively attached to the bottom, the periphery and the top of the generator 17, so that the coolant can dissipate heat from all sides of the generator 17, significantly improving the heat dissipation effect.

[0030] As a further description of the above technical solution: An infusion pump 14 is fixedly installed in the liquid storage cavity 13. A first conduit 25 is fixedly installed between the output end of the infusion pump 14 and the liquid outlet pipe 2. A second conduit 26 is fixedly installed between the liquid return pipe 21 and the liquid storage cavity 13. A heat exchanger 15 is fixedly installed in the liquid storage cavity 13.

[0031] Specifically, by setting the heat exchanger 15, the inside of the liquid storage cavity 13 can be continuously cooled, so that the coolant can always be maintained in a low temperature state, ensuring the heat dissipation effect of the coolant on the generator 17. By setting the infusion pump 14 and cooperating with the first conduit 25, the second conduit 26, the liquid outlet pipe 2 and the liquid return pipe 21, the coolant can be circulated and guided in the liquid storage cavity 13, the first heat dissipation pipe 22, the second heat dissipation pipe 23 and the third heat dissipation pipe 24.

[0032] As a further description of the above technical solution: Outer connecting pipes 31 with corresponding positions are fixedly installed on the peripheries of the liquid outlet pipe 2 and the liquid return pipe 21. A first sealing ring 34 is fixedly installed on the inner wall at the connection of the outer connecting pipe 31 and the first heat dissipation pipe 22. A movable rod 343 is slidably installed in the first heat dissipation pipe 22. A first spring 345 is fixedly installed between the first heat dissipation pipe 22 and the movable rod 343. A sealing pin 341 inserted into the first sealing ring 34 is fixedly installed at the outer end of the movable rod 343. A connecting seat 3 is fixedly installed at the upper end of the first heat dissipation pipe 22. The lower end of the second heat dissipation pipe 23 is inserted and installed on the upper end of the connecting seat 3. A second sealing ring 35 is fixedly installed on the inner side of the mating end faces of the connecting seat 3 and the second heat dissipation pipe 23. Limit sliding rods 352 are respectively fixedly installed on the back faces of the two second sealing rings 35. Sealing plates 351 inserted and connected with the limit sliding rods 352 are respectively arranged on the back faces of the two second sealing rings 35. A second spring 354 is fixedly installed between the adjacent second sealing ring 35 and the sealing plate 351. Push rods 355 are fixedly installed on the facing end faces of the two sealing plates 351. Limit insertion plates 342 are respectively fixedly installed on both sides of the inner cavity of the first heat dissipation pipe 22. Limit insertion rods 344 inserted into the limit insertion plates 342 are fixedly installed at both ends of the movable rod 343. The sealing pin 341 is fixedly installed at the outer end of the outer limit insertion rod 344. An inclined slot 346 is opened at the upper end of the movable rod 343. An inclined insertion block 356 inserted into the inclined slot 346 is fixedly installed at the lower end of the lower sealing plate 351.

[0033] When installing the heat conduction frame 16, the lower end of the second heat dissipation pipe 23 is inserted and installed on the upper end of the connecting seat 3;

[0034] First, through the contact effect between the two push rods 355, the two sealing plates 351 are pushed to move away from each other, so that the sealing plates 351 on both sides are separated from the second sealing ring 35, thereby enabling the second heat dissipation pipe 23 to communicate with the first heat dissipation pipe 22;

[0035] Second, due to the contact effect between the two push rods 355, when the lower sealing plate 351 moves downward, the movable rod 343 can be driven through the insertion effect between the inclined insertion block 356 and the inclined slot 346, so that the sealing pin 341 is separated from the first sealing ring 34, thereby enabling the first heat dissipation pipe 22 to communicate with the liquid outlet pipe 2 and the liquid return pipe 21;

[0036] The liquid outlet pipe 2 can inject the coolant into the first heat dissipation pipe 22, the second heat dissipation pipe 23 and the third heat dissipation pipe 24, and can inject the coolant inside the three into the liquid return pipe 21. After the generator 17 is installed, the circulation of the coolant around it is realized;

[0037] When disassembling the heat-conducting frame 16, the two push rods 355 are separated from each other. In cooperation with the second spring 354, the sealing plate 351 can be reset, so that the two side sealing plates 351 are reattached to the second sealing ring 35, and the lower end of the second heat-dissipating tube 23 and the upper end of the connecting seat 3 can be sealed. When the sealing plate 351 moving upward in the connecting seat 3 drives the oblique insertion block 356 to move upward, in cooperation with the first spring 345, the sealing pin 341 is reinserted into the first sealing ring 34, and the connection between the first heat-dissipating tube 22, the liquid outlet pipe 2 and the liquid return pipe 21 can be sealed. Furthermore, after the generator 17 is disassembled, the first heat-dissipating tube 22, the second heat-dissipating tube 23 and the third heat-dissipating tube 24 around it can be sealed, shortening the flow path of the coolant and not affecting the coolant flow around other generators 17.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
