Description
Technical field
The present invention relates to a kind of condenser, particularly a kind of heat exchanger structure and assembly method thereof.
Background technology
When room air conditioner moved at cooling condition, the room air evaporimeter of flowing through made temperature reduce.Simultaneously because the temperature of evaporator surface generally is starkly lower than the dew-point temperature of air, so air is when flowing through evaporator surface, and airborne part moisture will be separated out, thereby form condensate water at evaporator surface.Condensate water at evaporator surface should in time be drained.If it is more that condensate water is gathered at evaporator surface, with the obstruct airflow road, increase the flow resistance of air, reduce the efficient of evaporimeter: water droplet also might take place be blown into indoor situation, cause the off quality of air-conditioner.
Fin-tube heat exchanger is a heat exchanger pattern with the most use in the present refrigerating air conditioning device, and room air conditioner and air-cooled handpiece Water Chilling Units mostly adopt this heat exchanger.This heat exchanger is adding man-hour, is punching on fin, flange, and the height of flange is the spacing between fin, and the annulus that flange forms is enclosed within on the pipe, by expansion tube process fin is fixedlyed connected with pipe then.
Fig. 1 is the fin-tube type heat exchanger structural representation of prior art.As shown in Figure 1, it comprises: the fin 3 that banded aluminium foil cracks and forms through roll wave, the pipe single tube 1 that inserts in the fin 3 and realize by expand tube being connected with fin 3, and the elbow 2 that two adjacent pipe single tubes 1 are communicated with by the gas brazing welding, single tube 1 and elbow 2 are formed equally spaced serpentine coil.
But when the heat exchange amount requires greatly, fin-tube type heat exchanger thickness is restricted, require fin-tube type heat exchanger windward side size bigger, cause serpentine coil longer, the refrigerant circulation passage is longer, refrigerant is fluid interchange in coil pipe, formed gas phase zone, the gas-liquid two-phase district, the length ratio of liquid phase region is unreasonable, because flow process is longer, makes refrigerant through gas phase zone, after the heat exchange of gas-liquid two-phase district, the liquid phase region of formation is longer, and the heat exchange efficiency of the lower liquid phase region of refrigerant temperature is lower, caused the waste of heat exchange area, liquid phase region is long simultaneously makes cold resistance power increase, and these have had a strong impact on the performance of heat exchanger.
Simultaneously, fin flange and flat tube connected mode adopt soldering, and the cost height of soldering; And because the aluminium flake fusing point is low, the soldering control ratio is difficulty, makes the fin distortion easily and burns residual weld tabs; Can not guarantee that flange closely contacts with flat tube, causes radiating efficiency low.
Summary of the invention
Technical problem to be solved by this invention is to overcome deficiency that above-mentioned Fin-tube Condenser exists to provide a kind of and be easy to install and heat exchanger structure that the coefficient of heat transfer that is connected firmly is high.
The technical solution adopted in the present invention is:
A kind of heat exchanger structure, comprise inlet header, outlet header is arranged on the fin that closely piles up between inlet header and the outlet header, and running through the flat tube of fin with inlet header and outlet header connection, described fin offers the pipe-line tank that can allow flat tube to insert smoothly; The ring washer that annular shape and flat tube profile were complementary in it also comprised, described packing ring internal diameter is less than the thickness of flat tube.
Described packing ring internal diameter is than the little 0.1-5mm of flat tube.
Described flat tube is the microchannel aluminium flat conduit.
A kind of assembly method of heat exchanger structure as claimed in claim 1, (1) heats packing ring;
(2) be arranged on the plummer fin and packing ring are successively corresponding; (3) flat tube was inserted fin and packing ring in turn, and made flat tube can pass the cooling pad circle and form matched in clearance; (4) use the equipment of exerting pressure and promote to exert pressure platform,, fin and packing ring are fitted tightly to compress fin and packing ring; (5) keep constant voltage, pressure satisfies fin and washer arrangement is adjacent to, and to packing ring blast-cold gas, the cooling pad makes between packing ring and the flat tube interference fit to occur to normal temperature, thereby finish fixedlying connected of fin and flat tube, then flat tube is connected with collector.
The heating-up temperature of packing ring is 100-150 ℃.
The invention has the beneficial effects as follows: flat tube and packing ring interference fit, fin added be held between two packing rings, realize the fine location between fin and the flat tube, avoid occurring the relative displacement sliding phenomenon, and easily assembling; Fin is original four times with the contact area of heat radiation packing ring approximately, promoted the radiating efficiency of radiator, and fixed form has avoided soldering, has saved wlding, reduces cost.
