Description
Technical field
The utility model relates to a kind of air-conditioning concurrent flow heater cores.Belong to field of air conditioning.Be specially adapted to the engineering car air-conditioner.
Background technology
Along with the development of engineering truck industry, on-board air conditioner becomes the requisite part of automobile, and heater cores then is the vitals of engineering car air-conditioner.And heater cores that engineering truck adopts mostly is greatly the copper tube aluminum formula 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 heater cores of said structure then seem, and anti-decay property is poor; The flat tube of existing automobile air conditioner heater heater cores is generally single hole or two holes in addition, 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 utility model provide have more high efficiency, engineering truck is with a kind of air-conditioning concurrent flow heater cores cheaply, to reach the heat exchange efficiency that improves to the full extent heater cores, and so that surface temperature reaches the low flow resistance purpose of balance and low windage, decrease cost.
The technical scheme in the invention for solving the above technical problem is: a kind of air-conditioning concurrent flow heater cores, comprise left and right hydroecium, described left and right hydroecium is arranged in parallel, be 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: be respectively equipped with upper and lower backplate between left and right hydroecium two ends, described heat exchange fin is 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, heat exchange property and the fade resistance of concurrent flow heater cores.Two ends are respectively equipped with backplate, thereby when improving evaporimeter and air contact area, improve the stability of whole heater cores.
The utility model also is applicable to the heater cores of upper and lower hydroecium.
Advantage of the present utility model is as follows: 1, farthest improve heat exchange efficiency, make the heater cores 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.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model structural representation;
Fig. 2 is the heat exchange fin structural representation;
Fig. 3 is the flat tube configuration schematic diagram.
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, lower backplate; 12, heat exchange fin.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment as shown in Figure 1, a kind of air-conditioning concurrent flow heater cores is the left and right layout of hydroecium.Left 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, lower backplate 11 between left 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, so that whole heater cores consists of the integral body of a sealing.
Be equipped with support 2 on left hydroecium 3, the right hydroecium 9, support 2 is provided with screw rivet 1, so that heater cores is more convenient for installing.
Core material is full aluminium, decrease cost.
Operation principle of the present utility model is: the high temperature glycol after engine or fuel heater heating and water mixed liquid body enter left hydroecium 9 by inlet tube 7 partition 8 first halves, enter porous flat pipe 5 interior flowing, carry out carrying out heat exchange with corrugated fin 12, air, thereby heated air.Along with porous flat pipe 5 left hydroecium 3 high temperature glycol of inflow and water mixed liquid body mix again, enter left hydroecium 3 bottom porous flat pipes 5 interior flowing, carry out carrying out heat exchange with corrugated fin 12, air, thereby heated air.Along with flowing into right hydroecium bottom, porous flat pipe 5 enters outlet 10 outflows.The utility model 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, the inner flow resistance of core body and air drag are less, 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 utility model 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, the inner flow resistance of core body, air side windage have effectively been reduced, concurrent flow heater cores compression resistance, heat exchange property fade resistance have been strengthened, ethylene glycol and water mixed liquid body are 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 utility model specific implementation is not subjected to the restriction of aforesaid way, if the various improvement of having adopted method design of the present utility model and technical scheme to carry out, or directly apply to other occasion without improvement, all within protection domain of the present utility model.
