Abstract
The utility model relates to an air-jet impacting cold plate with flow burbling columns, which comprises a heat conducting plate (1), a flow jetting plate (2), a cover plate (3) and an interface flange (4); one end of the flow jetting plate (2) is provided with the interface flange (4), the heat conducting plate (1) is installed at the outer side face of the flow jetting plate (2), and the cover plate (3) is covered on the flow jetting plate (2); the matrices of flow burbling columns (5) are arranged on the heat conducting plate (1), and the matrices of flow jetting holes (6) are arranged on the flow jetting plate (2); and the relative positions of the flow burbling columns (5) and the flow jetting holes (6) are as follows: one flow jetting hole (6) is arranged between every four flow burbling columns (5). By the air-jet impacting cold plate with the flow burbling columns, the heat transfer coefficient of the cold plate is enhanced because of the reinforced heat transfer action of the flow burbling columns. Compared with a cold plate with no flow burbling column, the average temperature of a chip is lower. Moreover, the difference value of the temperature is in a rising trend along with the enhancement of the flow rate and the inlet pressure of air.
Description
Technical field
The utility model relates to a kind of cold drawing, relates in particular to a kind of air-spray with turbulence columns and impacts cold drawing.
Background technology
Since nineteen forties, digital computer came out, microelectric technique developed rapidly, used also more and more widely.Microchip develops to quicker, lighter, more small-sized direction, this makes the heating power of electronic component and density of heat flow rate more and more higher, the cooling heat transferring engineering is faced with formidable challenges, if heat can not in time be evacuated, heat problem will become the bottleneck of electron trade, seriously restrict its development and application.
At present, the most widely used blower fan forced convection that remains of electronic equipment dissipating heat is air-cooled, and this technology is simple, reliable, still along with the lifting of electronic device density of heat flow rate, has been difficult to satisfy the environmental condition requirement of system.
The utility model content
Technical problem to be solved:
Provide a kind of heat exchange coefficient that air-spray impacts cold drawing that improves at above problem the utility model, solved the heat dissipation problem of high heat flux electronic chip, the air-spray of the band turbulence columns of the functional reliability of enhancing electronic equipment impacts cold drawing.
Technical scheme:
A kind of air-spray with turbulence columns impacts cold drawing and comprises heat-conducting plate, fluidic plate, cover plate and flange; End in fluidic plate is provided with flange, and heat-conducting plate is installed in the fluidic plate lateral surface, is stamped cover plate on fluidic plate; Be provided with the turbulence columns matrix on heat-conducting plate, fluidic plate is provided with the jet orifice matrix; The relative position of turbulence columns and jet orifice is: be provided with a jet orifice in the middle of per four turbulence columns.
Beneficial effect:
The air-spray of band turbulence columns of the present utility model impacts cold drawing, because the enhanced heat exchange effect of turbulence columns, improved the heat exchange coefficient of cold drawing, compare with cold drawing not with turbulence columns, the mean temperature of chip is lower, and along with the raising of air mass flow and inlet pressure, temperature gap is in rising trend.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a heat-conducting plate structural representation of the present utility model;
Fig. 3 is a fluidic plate structural representation of the present utility model;
Fig. 4 is that jet orifice of the present utility model and cross section are the relative position figure of square turbulence columns.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
As shown in Figure 1, the air-spray of this band turbulence columns impact cold drawing comprises heat-conducting plate 1, fluidic plate 2, cover plate 3 and flange 4; End in fluidic plate 2 is provided with flange 4, and heat-conducting plate 1 is installed in fluidic plate 2 lateral surfaces, is stamped cover plate 3 on fluidic plate 2;
As Fig. 2, shown in Figure 3, on heat-conducting plate 1, be provided with turbulence columns 5 matrixes, fluidic plate 2 is provided with jet orifice 6 matrixes;
As shown in Figure 4, turbulence columns 5 with the relative position of jet orifice 6 is: be provided with a jet orifice 6 in the middle of per four turbulence columns 5, turbulence columns 5 can be foursquare turbulence columns for cylindrical turbulence columns, conical turbulence columns or cross section.
Turbulence columns links to each other with heat-conducting plate, has increased the volume of heat-conducting plate, helps thermal diffusion; The area of dissipation that increases helps heat exchange; Turbulence columns has changed the high velocity air normal flow direction after impacting, and has increased the turbulivity of air-flow, has improved convection transfer rate.
Though the utility model with preferred embodiment openly as above; but they are not to be used for limiting the utility model; anyly be familiar with this skill person; in the spirit and scope that do not break away from the utility model; can do various variations or retouching from working as, what therefore protection range of the present utility model should be defined with the application's claim protection range is as the criterion.
