Heat pipe nuclear reactor thermoelectric conversion waste heat direct discharge system and working method

Abstract

The invention discloses a heat pipe nuclear reactor thermoelectric conversion waste heat direct discharge system which comprises a water tank, a water tank outlet communicates with a plurality of coldplate heat exchanger inlets through a pipeline, an electric control valve and a circulating pump are arranged on the pipeline, cold plate heat exchanger outlets communicate with a shell heat exchanger inlet through a pipeline, and a shell heat exchanger outlet communicates with a water tank inlet. A shell heat exchanger is arranged in seawater. Heat conduction bases and thermoelectric power generation modules are arranged between adjacent cold plate heat exchangers, one ends of heat pipes of a nuclear reactor are inserted into the heat conduction bases, and fuel rods are arranged between theother ends of the heat pipes. Closed circulation is adopted, the conversion efficiency of a thermoelectric power generation device is improved, meanwhile, corrosion caused by direct contact between the interior of underwater equipment and outside seawater is avoided, the service life of the underwater equipment is prolonged, the underwater endurance time is prolonged, and meanwhile the controllability of an energy conversion system is improved; and besides, the waste heat discharge system is efficient and compact in structure and easy to install and maintain, the size of unmanned underwater equipment can be effectively reduced, and investment is reduced.

Description

technical field [0001] The invention belongs to the technical field of heat pipe reactor energy conversion, and in particular relates to a heat pipe nuclear reactor thermoelectric conversion waste heat direct discharge system. Background technique [0002] As a new type of marine equipment, unmanned submersibles will be the focus of research and development of underwater equipment in various countries in the future. Most of the existing unmanned submersibles are powered by traditional chemical energy sources, with low endurance and poor concealment, which seriously restrict their application. Semiconductor thermoelectric power generation technology is a technology that uses the Seebeck effect of materials to directly convert heat energy into electrical energy. It has a series of advantages such as compact structure, no wear, no leakage, clean, no noise, long life, and high reliability. It is a kind of Green and environmentally friendly power generation technology. Heat pip...
