Embodiment Construction

[0019] The liquid metal radiator is used for the internal heat dissipation of gas-insulated metal-enclosed switchgear to solve the problem of excessive temperature rise in the gas-insulated metal-enclosed switchgear cabinet. figure 1 This is a schematic diagram of the structure of the liquid metal radiator of this application, such as figure 1 As shown, the liquid metal heat sink includes a heat exchange element 1 and a heat dissipation element 2. When in use, the heat exchange element 1 is placed inside the gas-insulated metal enclosed switchgear 7, and the heat dissipation element 2 is placed in the external environment.

[0020] Both the heat exchange element 1 and the heat dissipation element 2 are provided with accommodating cavities, and the accommodating cavity of the heat exchange element 1 and the accommodating cavity of the heat dissipation element 2 are connected by a circulation pipe 3. The accommodating cavity of the heat exchange element 1 contains the liquid metal...

Abstract

The application discloses a liquid metal radiator. The liquid metal radiator comprises a heat exchange part, a radiating part, a circulating pipeline and a driving pump and like components; through the cooperation of above components, the physical characteristic that the liquid metal is low in melting point and high in high-temperature heat conductivity is used for cooling the internal of the cabinet of the gas-insulated metal closed switch equipment, and the problem that the temperature rise in the gas-insulated metal closed switch equipment is excessively high is effectively solved. In the liquid metal radiator disclosed by the application, the liquid metal is used as the circulating cooling liquid, compared with the traditional air, water, non-metallic medium and like cooling mediums, and the liquid metal has higher heat conductivity, so that the liquid metal has more efficient heat transport and extreme radiating capacity. Furthermore, the liquid state is hard to evaporate, hard toleak, safe and non-toxic, and stable in physic-chemical property, and capable of guaranteeing efficient, long-term and stable running of the radiator.

Description

Technical field [0001] This application relates to the technical field of heat dissipation of switchgear, in particular to a liquid metal radiator. Background technique [0002] Switchgear is a kind of power equipment that opens and closes, controls and protects in the process of power generation, transmission, distribution, and power conversion of the power system. The components in the switch cabinet include circuit breakers, disconnect switches, load switches, operating mechanisms, transformers and various protection devices. At present, commonly used switch cabinets include gas-insulated metal-enclosed switchgear. [0003] Gas-insulated metal-enclosed switchgear (hereinafter referred to as switchgear) uses SF6 and other gases as the main insulating medium, uses a vacuum interrupter as a switch arc component, and seals the vacuum interrupter and primary conductive circuit in an epoxy resin shell Or stainless steel gas box. Since the epoxy resin shell or stainless steel air bo...
