Description
Technical field
The present invention relates to a kind of concurrent flow warm braw core body.Belong to field of air conditioning.Be specially adapted to the engineering car air-conditioner.
Background technology
Along with the continuous development of engineering truck industry, on-board air conditioner becomes the requisite part of automobile, and the warm braw core body then is the vitals of engineering car air-conditioner.And engineering truck adopts the warm braw core body to be the copper tube aluminum formula mostly at present, and surface temperature is inhomogeneous, and heat exchange efficiency is low, and cost is high.The not anti-wind locking because the work under bad environment of engineering truck, the warm braw core body of said structure then seem, and anti-decay property is poor; The flat tube of existing in addition air conditioning for automobiles heater warm braw core body is generally single hole or two holes, and intensity is low, and withstand voltage properties can not satisfy the requirement of engineering truck.
Summary of the invention
For overcoming the deficiency of prior art; The present invention provides a kind of and has more high efficiency, engineering truck is with concurrent flow warm braw core body cheaply; To reach the heat exchange efficiency that improves the warm braw core body to the full extent; And make surface temperature reach balance and the low flow resistance purpose of low windage, reduced cost significantly.
The present invention addresses the above problem the technical scheme that is adopted: a kind of concurrent flow warm braw core body; Comprise left and right hydroecium, described left and right hydroecium is arranged in parallel, and is connected with a plurality of flat tubes between the left and right hydroecium; The two ends of flat tube are inserted in the through hole of left and right hydroecium left and right hydroecium are communicated with; Be provided with heat exchange fin between the flat tube, it is characterized in that: between left and right hydroecium two ends, be respectively equipped with upper and lower backplate, the said fin that changes is a corrugated fin; Described flat tube is the porous flat pipe at least three holes.
The height of described corrugated fin is preferably 6-9mm.
Be provided with corrugated fin between the porous flat pipe, the structure that this kind porous flat pipe cooperates with corrugated fin has strengthened compression resistance property, heat exchange property and the fade resistance of concurrent flow warm braw core body.Two ends are respectively equipped with backplate, thereby when improving evaporimeter and air contact area, improve the stability of whole warm braw core body.
The present invention also is applicable to the warm braw core body of upper and lower hydroecium.
Advantage of the present invention is following: 1, farthest improve heat exchange efficiency, make warm braw core surface temperature more even; 2, have lightweight characteristics; 3, processing technology is simple, is fit to large-scale production; 4, easy for installation, improve evaporator assembly production efficiency.

Among the figure: 1, screw rivet; 2, support; 3, left hydroecium; 4, upper guard board; 5, flat tube; 6, blanking cover; 7, inlet tube; 8, partition; 9, right hydroecium; 10, outlet; 11, following backplate; 12, heat exchange fin.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Embodiment as shown in Figure 1, concurrent flow warm braw core body are the left and right layout of hydroecium.Left side hydroecium 3 is arranged in parallel with right hydroecium 9, is connected with a plurality of porous flat pipes 5 between left hydroecium 3 and the right hydroecium 9; As shown in Figure 3, flat tube 5 has three holes.The middle part of right hydroecium 9 is provided with partition 8; Right hydroecium 9 is provided with inlet tube 7, outlet 10; As shown in Figure 2, be provided with corrugated fin 12 between the flat tube 5; The height of corrugated fin is 8mm.Be respectively equipped with upper guard board 4, following backplate 11 between left side hydroecium 3 and right hydroecium 9 two ends, thereby when improving evaporimeter and air contact area, improve the stability of whole evaporimeter.
Two ends at left hydroecium 3, right hydroecium 9 are equipped with blanking cover 6, make whole warm braw core body constitute the integral body of a sealing.
Be equipped with support 2 on left side hydroecium 3, the right hydroecium 9, support 2 is provided with screw rivet 1, makes the warm braw core body be more convenient for installing.
Core material is full aluminium, has reduced cost significantly.
Operation principle of the present invention is: high temperature glycol after engine or fuel heater heating and water mixed liquid body get into partition 8 first halves of left hydroecium 9 through inlet tube 7; Get in the porous flat pipe 5 and flow; Carry out carrying out heat exchange, thereby heated air with corrugated fin 12, air.Along with porous flat pipe 5 left hydroecium 3 high temperature glycol of inflow and water mixed liquid body mix once more, get in the left hydroecium 3 bottom porous flat pipes 5 to flow, carry out carrying out heat exchange, thereby heated air with corrugated fin 12, air.Along with flowing into right hydroecium bottom, porous flat pipe 5 gets into outlet 10 outflows.The present invention effectively utilizes porous flat pipe 5, corrugated fin 12 structures; Ethylene glycol and water mixed liquid body and flat tube 5 and air side heat exchange area are increased, and inner flow resistance of core body and air drag are littler, core body flow process appropriate design; Make surface temperature more even; Increase unit interval inner refrigerant flow, improved the coefficient of heat transfer, improved heat exchange efficiency.
The present invention has adopted porous flat pipe, corrugated fin structure, U flow process or single process runner distribution mode and rational feed tube and escape pipe arrangement; Reduced the inner flow resistance of core body, air side windage effectively, strengthened concurrent flow warm braw core body compression resistance property, heat exchange property fade resistance, ethylene glycol and water mixed liquid body have been carried out scientific and reasonable regulating and distributing; Make surface temperature more even; Increase unit interval inner refrigerant flow, improved the coefficient of heat transfer, improved heat exchange efficiency; Simple in structure, practical more economically.
Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way, if the various improvement of having adopted method design of the present invention and technical scheme to carry out, or directly apply to other occasion without improvement, all within protection scope of the present invention.
