Abstract
The utility model discloses a micro-channel flat tube used for a parallel current evaporator. The flat tube comprises a flat tube body (1), guide grooves (2) are formed in the two sides of the flat tube body (1), the guide grooves (2) can enable condensate water generated by the parallel current evaporator in the process of heat exchanging to be discharged out of the parallel evaporator timely and effectively, the guide grooves (2) are multiple, and the plurality of guide grooves (2) are distributed in parallel along the length direction of the flat tube body (1). With the special structure, the guide grooves are adopted in the micro-channel flat tube used for the parallel current evaporator, the condensate water can be discharged timely and effectively, phenomena of freezing and frosting are greatly prevented from happening, and the situation that splashing of water drops has affects on comfort of passengers is avoided. The introduction of the guide grooves can enable the condensate water to be discharged timely, the situation that due to local accumulation of the condensate water, local heat exchanging is not smooth is avoided, and temperature evenness of the surface of the parallel current evaporator is improved.
Description
Technical field
The utility model relates to the air conditioning for automobiles field, especially relates to a kind of parallel-flow evaporator micro-channel flat.
Background technology
For the heat exchange efficiency that improves the used for automobile air conditioning evaporimeter, reduce its installation footprint and weight, its version develops into stacked from pipe type, corrugated tube type, laminated evaporator is again by more compact structure at present, heat exchange efficiency is higher, surface temperature is more even, and the simple more parallel flow evaporators of processing technology replaces.
Parallel-flow evaporator adopts heat exchange porous flat pipe and fin efficiently, can improve heat exchange efficiency, yet these new technologies also have some problems to need to be resolved hurrily in the process of using, as: the temperature homogeneity of evaporator surface is relatively poor, drainage is not smooth, for solving the technology that draining increases hydrophilic treated, increasing cost virtually again.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of parallel-flow evaporator micro-channel flat at problems of the prior art, and its objective is increases the unobstructed property of parallel-flow evaporator draining, and then makes the temperature of evaporator surface more even.
The technical solution of the utility model is this kind parallel-flow evaporator micro-channel flat, described flat tube comprises the flat tube body, and the both sides of flat tube body are provided with the condensed water that parallel-flow evaporator is produced and discharge guiding gutter outside the parallel-flow evaporator timely and effectively in the process of heat exchange.
Described guiding gutter has a plurality of, and a plurality of guiding gutter is along the parallel distribution of the length direction of flat tube body.
This kind parallel-flow evaporator with said structure has the following advantages with micro-channel flat:
1. this kind parallel-flow evaporator increases guiding gutter with micro-channel flat by the both sides at flat tube, the condensed water that parallel-flow evaporator is produced in the process of heat exchange is discharged outside the parallel-flow evaporator timely and effectively, be unlikely to cause condensed water to gather, can be timely and effectively with the condensed water draining, prevented generation icing, the frosting phenomenon greatly, and water-drop sputtering influences passenger comfort.
2. this kind parallel-flow evaporator can be discharged condensed water timely with quoting of micro-channel flat guiding gutter, has avoided the caused local heat exchange of gathering of partial condensation water not smooth, has improved the temperature homogeneity on parallel-flow evaporator surface.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view of structure shown in Figure 1.
In Fig. 1-2,1: the flat tube body; 2: guiding gutter.
The specific embodiment
By the combination of structure shown in Fig. 1-2 as can be known, this kind parallel-flow evaporator comprises flat tube body 1 with micro-channel flat, and the both sides of flat tube body 1 are provided with the condensed water that parallel-flow evaporator is produced and discharge guiding gutter 2 outside the parallel-flow evaporator timely and effectively in the process of heat exchange, guiding gutter 2 has a plurality of, and a plurality of guiding gutter 2 is along the parallel distribution of the length direction of flat tube body 1.
This kind parallel-flow evaporator increases guiding gutter 2 with micro-channel flat by the both sides at flat tube body 1, the condensed water that parallel-flow evaporator is produced in the process of heat exchange is discharged outside the parallel-flow evaporator timely and effectively, be unlikely to cause condensed water to gather, and then increase flowing resistance, influence local heat exchange, and then cause the temperature difference on parallel-flow evaporator surface bigger.
Operation principle of the present utility model is: cold-producing medium flows in porous flat pipe, and the air that is cooled is along the porous flat pipe flows outside, and cold-producing medium is met thermal evaporation, absorbs airborne heat, thus the cooling air.Parallel-flow evaporator is started working after air-conditioning system starts, and fin surface produces condensed water, and condensed water is discharged from evaporator surface timely and effectively by the guiding gutter of micro-channel flat.
Superior effect of the present utility model is: adopted the micro-channel flat of band guiding gutter prevented generation icing, the frosting phenomenon greatly, and water-drop sputtering to influence passenger comfort timely and effectively with the condensed water draining; Quoting of guiding gutter can be discharged condensed water timely, avoided the caused local heat exchange of gathering of partial condensation water not smooth, improved the temperature homogeneity on parallel-flow evaporator surface.
Claims (2)
1. parallel-flow evaporator micro-channel flat, it is characterized in that: described flat tube comprises flat tube body (1), and the both sides of flat tube body (1) are provided with the condensed water that parallel-flow evaporator is produced and discharge guiding gutter (2) outside the parallel-flow evaporator timely and effectively in the process of heat exchange.
2. a kind of parallel-flow evaporator micro-channel flat according to claim 1, it is characterized in that: described guiding gutter (2) has a plurality of, and a plurality of guiding gutter (2) is along the parallel distribution of length direction of flat tube body (1).
