Description

Technical Field

[0001] The embodiments of the present application relate to the field of hot gas variable capacity power generation devices, and specifically to a power generation system that utilizes the thermal energy of a reactor to generate electricity. Background Art

[0002] The statements herein merely provide background information related to the present application and do not necessarily constitute prior art.

[0003] The Stirling engine outputs power through a cycle of cooling, compression, heat absorption, and expansion of the working medium (hydrogen or helium) in the cylinder. It is a commonly used thermoelectric conversion method with the characteristics of high conversion efficiency and good reliability. It is widely used in heat pipe reactor power systems.

[0004] During the power generation process, the heat generated by the reactor core is usually transferred to the Stirling generator using the reactor heat pipe, and the waste heat of the Stirling generator is discharged using the heat dissipation device. However, the Stirling generator will vibrate during the power generation process, and the vibration of the Stirling generator will be transmitted to the heat pipe, the core and the heat dissipation device, causing the heat pipe, the core and the heat dissipation device to be damaged due to the influence of vibration, which brings safety problems. Summary of the invention

[0005] A brief overview of the present application is provided below in order to provide a basic understanding of certain aspects of the present application. It should be understood that this overview is not an exhaustive overview of the present application. It is not intended to identify the key or important parts of the present application, nor is it intended to limit the scope of the present application. Its purpose is merely to present certain concepts in a simplified form as a prelude to a more detailed description discussed later.

[0006] A vibration reduction device is usually used to reduce or alleviate the vibration of the Stirling generator to avoid damage to the heat pipe, core and heat dissipation device due to vibration. In the related art, multiple active vibration absorbers are usually used or the movement phases of two Stirling generators are opposite to each other to reduce or alleviate the vibration. However, the above two methods have a single point failure problem, that is, when one of the multiple active vibration absorbers or one of the two Stirling generators has a problem, the vibration reduction function will completely fail and the reliability is low.

[0007] In response to at least one aspect of the above-mentioned problems, an embodiment of the present application provides a power generation system that utilizes the thermal energy of a reactor to generate electricity. The reactor includes a core and a plurality of heat pipes. The plurality of heat pipes are arranged in the core for transferring heat provided by the core to the power generation system.

[0008] The power generation system provided by the embodiment of the present application includes a shell, a power generation device, a heat sink and a vibration reduction assembly. The power generation device is arranged inside the shell and is thermally connected to a plurality of heat pipes to generate electricity using the heat of the heat pipes; the heat sink is arranged outside the shell and is fixedly connected to the shell, and the heat sink is also thermally connected to the power generation device to cool the power generation device to discharge waste heat; the vibration reduction assembly is arranged inside the shell and is fixedly connected to the shell and the power generation device to reduce the influence of the vibration of the power generation device on the plurality of heat pipes and the heat sink; wherein a first heat transfer medium is arranged between the power generation device and the plurality of heat pipes to enhance the heat conduction capacity between the power generation device and the heat pipes; a second heat transfer medium is arranged between the power generation device and the heat sink to enhance the heat conduction capacity between the power generation device and the heat sink.

[0009] The vibration reduction assembly of the power generation system provided in the embodiment of the present application can reduce the influence of the vibration of the power generation device on multiple heat pipes and the heat dissipation device, thereby protecting the heat pipes, the core and the heat dissipation device; at the same time, the first heat transfer medium arranged between the power generation device and the multiple heat pipes, and the second heat transfer medium arranged between the power generation device and the heat dissipation device can play a damping role in the vibration of the power generation device, which is also beneficial to reducing the influence of the vibration of the power generation device on the multiple heat pipes and the heat dissipation device, and can also protect the heat pipes, the core and the heat dissipation device; through the cooperation of the vibration reduction assembly and the first heat transfer medium and the second heat transfer medium, even if the vibration reduction assembly fails completely, the heat pipes, the core and the heat dissipation device can still be protected by the first heat transfer medium and the second heat transfer medium, which is beneficial to improving the reliability of the power generation system.

[0028] The vibration reduction assembly 40 of the power generation system 100 provided in the embodiment of the present application can reduce the influence of the vibration of the power generation device 20 on the multiple heat pipes 200 and the heat dissipation device 30, thereby protecting the heat pipes 200, the core and the heat dissipation device 30; at the same time, the first heat transfer medium arranged between the power generation device 20 and the multiple heat pipes 200, and the second heat transfer medium arranged between the power generation device 20 and the heat dissipation device 30 can play a damping role in the vibration of the power generation device 20, which is also beneficial to reducing the influence of the vibration of the power generation device 20 on the multiple heat pipes 200 and the heat dissipation device 30, and can also protect the heat pipes 200, the core and the heat dissipation device 30; through the cooperation of the vibration reduction assembly 40 and the first heat transfer medium and the second heat transfer medium, even if the vibration reduction assembly 40 fails completely, the heat pipes 200, the core and the heat dissipation device 30 can still be protected by the first heat transfer medium and the second heat transfer medium, which is beneficial to improving the reliability of the power generation system 100.

[0029] In some embodiments, the power generation device 20 may be a Stirling generator. In some embodiments, the reactor may be a heat pipe reactor, such as a space heat pipe reactor, a ground heat pipe reactor or an ocean heat pipe reactor. The space heat pipe reactor may be, for example, a lunar heat pipe reactor or a Martian heat pipe reactor.
