Abstract

The invention provides a radiator and a cogeneration system comprising the radiator. The radiator comprises a base tube and external fins, wherein the external fins are closed, each closed external fin comprises a fin body and a sealing piece sealing the fin body, and each closed fin is in the shape of a parabola from the lower portion of the base tube to the upper portion of the base tube. According to the intelligent cogeneration system, the structure of the radiator is optimized to enable heat exchanging efficiency to be maximized, and then energy is saved and the environment is protected.

Description

technical field [0001] The invention belongs to the field of heat exchangers, in particular to a radiator in the field of combined heat and power generation, and belongs to the field of F28 heat exchangers and the field of F24D heat supply. Background technique [0002] Among the radiators, finned tube radiators are widely used at present. The heat dissipation area can be enlarged and the heat exchange effect can be enhanced through the fins. However, the radiator type of the finned tubes and the setting of the finned tube parameters all affect the cooling effect. Good or bad, and in the current situation of energy crisis, there is an urgent need to save energy and meet the sustainable development of society. Maximize thermal efficiency to save energy and achieve the purpose of environmental protection and energy saving. [0003] In addition, in the current cogeneration system, the steam extraction volume of the steam turbine cannot be automatically controlled, nor can it b...
