Heat pipe pile waste heat removal system

Abstract

The embodiment of the invention relates to the technical field of deep sea nuclear power systems, and provides a heat pipe pile waste heat removal system. The heat pipe pile waste heat removal systemcomprises a heat pipe pile and a heat exchanger; the heat pipes of the heat pipe stack are in a horizontal lying state; the heat exchanger comprises a shell; the heat pipes are inserted into the shellin a penetrating mode; the shell comprises an inner layer shell body and an outer layer shell body; a water outlet and a water inlet are formed in the upper portion and lower portion of the shell which are corresponding to each other; the interior of the inner layer shell body is communicated with the exterior of the outer layer shell body through the water outlet and the water inlet. According to the heat pipe pile waste heat removal system provided by the embodiments of the invention, a special cooler is omitted, so that the system is simplified in structure and is reduced in size and can assist in saving precious cabin space compared with a traditional reactor waste heat removal system. The heat pipe pile waste heat removal system can be suitable for underwater vehicles with extremelynarrow internal space.

Description

technical field [0001] The invention relates to the technical field of deep-sea nuclear power systems, in particular to a heat pipe stack waste heat discharge system. Background technique [0002] Unmanned underwater vehicle (UUV for short) is an effective tool for deep-sea scientific investigation, resource survey, development and utilization, and underwater specific task execution. When meeting the requirements for output power and endurance time, nuclear power plants with high energy density, long life, and independent of air are often used as power sources. Restricted by the precious space resources in the deep sea, complex underwater environment and unmanned conditions, advanced reactors must be used. [0003] At present, many researches on heat pipe reactors have been carried out at home and abroad, covering the ocean, land and space. The heat pipe reactor (abbreviation: heat pipe reactor) is an all-solid-state reactor core, which uses heat pipes as the core heat exp...
