High-efficiency heat radiation structure and method for photovoltaic power generation prefabricated substation

Abstract

The invention relates to a high-efficiency heat radiation structure for a photovoltaic power generation prefabricated substation. A protection casing of the photovoltaic power generation prefabricated substation is a casing, wherein the casing comprises a framework (2) and a casing cover (1), wherein the casing cover is a liftable casing cover, a jacking and fixing device is arranged between the liftable casing cover and the framework, for the jacking and fixing device, an upper inner side of the casing framework and a corresponding bottom inner side of the casing cover are fixed with a lower horizontal hole board and an upper horizontal hole board, a space capable of accommodating a jack is arranged between the lower horizontal hole board and the upper horizontal hole board, vertical holes of the lower horizontal hole board and the upper horizontal hole board correspond mutually, connection bolts of sheath positioning supporting circular pipes penetrate through the vertical holes of the lower horizontal hole board and the upper horizontal hole board and are then screwed with nuts, four edges of the casing cover are fixed with rain shield baffle board modules, and four corners at a top portion of the casing cover are provided with rotary pull type rain shield baffle boards. The high-efficiency heat radiation structure is advantaged in that the structure is compact, high transportation requirements are satisfied, heat radiation efficiency during operation is high, operation is simple and convenient, strong applicability and high reliability are realized, and modular production application is realized.

Description

technical field [0001] The invention relates to a high-efficiency heat dissipation structure of a photovoltaic power generation prefabricated substation. The present invention also relates to a method for efficiently dissipating heat from a photovoltaic power generation prefabricated substation using the structure. Background technique [0002] Photovoltaic power generation prefabricated substations generally operate outdoors with better lighting conditions. In order to reduce the impact of the outdoor environment, IP33 box-type enclosures are generally designed for protection, which will generate an additional temperature rise of 10K or higher for the product. [0003] Existing photovoltaic power generation prefabricated substations generally use 35KV products. The height of this type of product is often large, but for the convenience of transportation, there are strict restrictions on the size of the product in the height direction. Therefore, this type of product usually ...

Problems solved by technology

[0003] Existing photovoltaic power generation prefabricated substations generally use 35KV products. The height of this type of product is often large, but for the convenience of transportation, there are strict restrictions on the size of the product in the height direction. Therefore, this type of product usually needs to be designed in a compact form. The area of ​​the air outlet at the top of the body is small, which is not conducive to the smooth flow of hot air, thus affecting the heat dissipation effect
