Description

High-efficient heat-dissipating gilled radiator
Technical field
The utility model belongs to oil-filled transformer component technology field, and in particular to a kind of high-efficient heat-dissipating chip radiating Device.
Background technology
As is known in the industry, need to be in oil-filled transformer body in order to ensure oil-filled transformer is run steadily in the long term The both sides of long side direction configure gilled radiator, chip radiating by means of flange connection or other similar connected modes Device forms circulation cooling circuit with the conduction oil inside oil-filled transformer, plays and the iron core inside oil-filled transformer is cooled down Effect, controlled the temperature rise of oil-filled transformer, ensure the normal operation and safety of power supply-distribution system.
Nowadays the structure that the radiator of in the market is all connected using oil inlet pipe, fin with flowline mostly is dissipated Heat, and at present most of fin runner transformer oil by when can all produce thermal boundary layer hinder transformer oil radiating, and And the air flow property between fin is poor, transformer oil is caused can not often to cool the temperature to desired level.
In prior art, one kind " transformation for being provided such as Chinese utility model patent Authorization Notice No. CN201773665U Device tangential fin heat radiator ", but for example one kind disclosed in Chinese utility model patent Authorization Notice No. CN202258670U " changes Enter the transformer radiator of structure " etc., the drawbacks of above-mentioned be present, and Chinese invention patent application publication No. CN106683831A The one kind " special-shaped oil duct gilled radiator " recommended, it forms heat radiation oil duct irregular special-shaped oil duct by pad, reaches Secondary Flow is formed to the fluid made in heat radiation oil duct and plays the purpose destroyed deep fat boundary layer and use raising heat transfer coefficient, but It is by the way of forward and backward fin is connected to each other by pad, its bonding strength is relatively low, the risk of oil leak be present.
In view of above-mentioned have problem, it is necessary to which the structure of existing gilled radiator is reasonably improved.Therefore, this Shen Ask someone to have made actively effectively to explore, form technical scheme described below finally.
The content of the invention
The purpose of this utility model is to provide a kind of high-efficient heat-dissipating gilled radiator, helps to improve heat radiating fin structure So that fluid produces Secondary Flow and destroys fluid thermal boundary layer and use and greatly improve heat dispersion, be advantageous to optimize attachment structure Using reduces oil leak risk and improves compressive resistance, increases the service life.
The purpose of this utility model is such to what is reached, a kind of high-efficient heat-dissipating gilled radiator, including oil inlet pipe, goes out Oil pipe and one group not only longitudinally of one another it is parallel configure spaced reciprocally again between oil inlet pipe and flowline for by oil inlet pipe The fin for leading to flowline is returned after the high-temperature oil liquid radiating of introducing, one group of fin is respectively by preceding fin and rear groups of fins Into, it is characterised in that:Set respectively in the opening position to correspond to each other between described preceding fin and described rear fin Have a preceding hole flanging and rear hole flanging, described preceding hole flanging has an a plurality of rows being spaced apart from top to bottom, in each row before Hole flanging is spaced, and the position of the preceding hole flanging in upper and lower two adjacent courses is mutually staggered, and described rear hole flanging equally has certainly It is upper and under a plurality of rows for being spaced apart, the rear hole flanging in each row is spaced, and in upper and lower two adjacent courses after The position of hole flanging is mutually staggered, and punching press is fused into one and in each other at the edge of the corresponding preceding hole flanging in position and rear hole flanging Between form riveted holes, be provided with rivet in described riveted holes, the rivet in preceding hole flanging and rear hole flanging melt each other by punching press The edge of conjunction, and by preceding hole flanging and rear the hole flanging edge that punching press is merged each other by between preceding fin and rear fin Heat radiation oil duct is separated to form runner staggeredly.
In a specific embodiment of the present utility model, described preceding hole flanging and rear hole flanging are at the edge that punching press is merged Place has a circle antiseepage bakie.
In another specific embodiment of the present utility model, the cross sectional shape of described antiseepage bakie takes the shape of the letter U.
In another specific embodiment of the present utility model, the centre of described rivet has a through hole.
In another specific embodiment of the present utility model, the both sides of described one group of fin are respectively arranged with more Piece connecting rod, using being welded and fixed between described connecting rod and described fin.
Also have a specific embodiment of the present utility model, one end of described oil inlet pipe form have one be used for The oil inlet pipe adapting flange of the transformer oil-out mating of oil-filled transformer, and the other end of oil inlet pipe is closed.
In an of the present utility model and then specific embodiment, one end of described flowline form have one be used for The flowline adapting flange of the transformer oil inlet mating of oil-filled transformer, and the other end of flowline is closed.
Of the present utility model more and in a specific embodiment, described preceding fin and rear fin are stainless steel Plate.
After the utility model uses said structure, have the advantage that:Firstly, since employ forward and backward hole flanging punching press Riveting makes to form runner staggeredly in fin, thus transformer oil in runner staggeredly by when can produce Secondary Flow and play Deep fat boundary layer is destroyed, so as to enhance cooling effect;Secondly as antiseepage bakie is provided with hole flanging edge, in punching press When by instantaneous pressure make forward and backward fin is thinning to be fused into one, while riveted holes are formed among hole flanging, and riveting Rivet is set in hole, thus not only reduces the oil leak risk at hole flanging edge, and improves the compressive resistance of fin, makes to dissipate Hot device entirety voltage endurance capability brings up to 200KPa;3rd, the through hole among rivet adds the mobility of air, when air passes through When produce flow-disturbing, convection transfer rate is lifted, so as to further enhancing the cooling effect of radiator.
