The specific embodiment
When the surface of radiating fin in the radiator formed hotting mask, this layer hotting mask can stop the heat exchange between cooling medium and the radiating fin, reduced the heat transfer efficiency of radiating fin, therefore will eliminate the hotting mask on radiating fin surface.
The approach of eliminating hotting mask is to make cooling fluid form turbulent flow, eliminates hotting mask by turbulent flow in the souring on radiating fin surface.Make cooling fluid form turbulent flow, the Reynolds number of cooling fluid (Ra=v/ υ, v is a rate of flow of fluid, υ is a fluid viscosity, Ra is a Reynolds number) just can not be lower than certain numerical value (generally being not less than 2400), the desired flow velocity of the fluid that viscosity is big is high more, and fluid resistance (abbreviating flow resistance as) and flow velocity square be directly proportional therefore also increase thereupon of flow resistance when flow velocity is high.Heat transfer efficiency and flow resistance are two aspects that contradiction exists, and flow resistance is the heat transfer efficiency height greatly then, and the little then heat transfer efficiency of flow resistance is low.If therefore adopt the method that improves the cooling fluid flow velocity to make when cooling fluid forms turbulent flow, though eliminated the hotting mask on radiating fin surface, the raising of flow velocity directly causes flow resistance to increase, and directly influences the working condition of cooling water pump circulation.The utility model applicant improves the structure of radiating fin, under the situation that does not increase the cooling fluid flow velocity, make cooling fluid form turbulent flow, eliminate the hotting mask on radiating fin surface, reach the purpose that improves heat transfer efficiency, and radiating fin simple in structure, processing technology is easy, expense is lower.
