Abstract

The invention provides a heat radiator and a combined heat and power generation system including the same. The heat radiator comprises a base tube and external fins, the external fins are sealed, the sealed external fins comprise fins and a sealing sheet for sealing the fins, and the distance between the sealing sheet and the base tube gets closer from the lower portion of the base tube to the upper portion of the base tube. According to the heat radiator and the combined heat and power generation system, the structure of the heat radiator is optimized, heat transfer efficiency of the heat radiator is maximized, energy is saved, and the purposes of environmental protection and energy saving are achieved.

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 i...
