Abstract
The utility model relates to a tube belt type evaporator for an air conditioner system of an automobile, particularly of a mini microbus. Both ends of each set of flat tube are provided with a liquid collecting tube outlet end and a liquid collecting tube inlet end; two sets of flat tubes adopt an upright front and back folding. The liquid collecting tube outlet end of one set of flat tube is communicated with the liquid collecting tube outlet end of the other set through a gas outlet tube; the liquid collecting tube inlet end of one set of flat tube is communicated with the liquid collecting tube inlet end of the other set through a liquid inlet tube. Both liquid collecting tube inlet ends are respectively positioned on both ends of the evaporator; both liquid collecting tube outlet ends are also respectively positioned on both ends of the evaporator; therefore, both sets of flat tubes carry out the incongruous folding and share an integrated fin.
Description
The utility model is to be applied to automobile particularly to be applied to band-tube evaporator in the mini van a/c system, particularly to the improvement of evaporation structure.
Because the structure of utility van and crew member distribute, its a/c system evaporator great majority adopt pipe sheet type structure at present.The heat exchange efficiency of pipe type evaporator will be lower than band-tube evaporator.As in the utility van a/c system, adopting band-tube evaporator, exist the structure of band-tube evaporator to be unsuitable for the shortcoming of utility van structure again.Utility van generally divides air channel, the left and right sides, and evaporation core body is elongated shape, as adopting band-tube evaporator and being designed to and pipe type refrigerant flow direction horizontal mode roughly the same, then is difficult to solve the problem of impeded drainage.As designing by car vertical mode commonly used, then because evaporator core is long, evaporator in-out end excessive temperature differentials, leaving air temp is extremely inhomogeneous.In view of above-mentioned technical barrier, few band-tube evaporator that adopts on the evaporator designs of utility van a/c system still adopts the low pipe type evaporator of heat efficiency at present
The purpose of this utility model is to solve above-mentioned technical barrier, the band-tube evaporator that provides a kind of utility van a/c system to use.
The purpose of this utility model is to realize like this.Incorgruous superimposed band-tube evaporator has two groups to be continuous U-shaped flat tube 7, is fixed with fin 5 on the flat tube, and every group of flat tube two ends all have collector tube exit end and collector tube entrance point; Two groups of flat tubes adopt vertical front and back superimposed; The collector tube exit end 1 of one group of flat tube is communicated with the collector tube exit end 4 of another group by freeing pipe 2; The collector tube entrance point 6 of one group of flat tube is communicated with the collector tube entrance point 8 of another group by feed tube 3.Two collector tube entrance points lay respectively at the two ends of evaporator, and two collector tube exit end also lay respectively at the two ends of evaporator, the incorgruous layout of flat tube import and export.
Available fin 5 connects between two groups of flat tubes, and promptly fin is whole shared between the flat tube.
Band-tube evaporator is adopted the utility model structure, make mobile two parts that are divided into of refrigerant side flow in opposite directions from two ends, for any end of evaporator, all be that low temperature liquid or liquid phase are two main phase refrigerants and the front and back stack of crossing hot refrigerant vapor like this.For each section in the middle of the evaporator, its refrigerant side mass dryness fraction stack situation is also suitable.Make on whole length direction that like this low temperature liquid refrigerant is evenly distributed, guaranteed more uniform evaporating temperature from the whole structure of fore-and-aft direction, guaranteed the uniform leaving air temp of evaporator by wind side interchange of heat (the end wise air quantity is evenly distributed), thereby satisfy the requirement of air conditioning comfortableness, make the higher heat exchanger of this efficient of tube-strip heat exchanger on utility van, to be applied.
The utility model is provided by following examples and accompanying drawing thereof.
Accompanying drawing is the utility model structural representation.
1 collector tube exit end A, 2 freeing pipes, 3 feed tubes, 4 collector tube exit end B, 5 fins, 6 collector tube entrance point A, 7 flat tubes, 8 collector tube entrance point B.
Embodiment:
There are two groups to be between 7 liang of groups of continuous U-shaped flat tube flat tube with fin 5 connections.Every group of flat tube two ends all have collector tube exit end and collector tube entrance point; Two groups of flat tubes adopt vertical front and back superimposed; The collector tube exit end 1 of one group of flat tube is communicated with the collector tube exit end 4 of another group by freeing pipe 2; The collector tube entrance point 6 of one group of flat tube is communicated with the collector tube entrance point 8 of another group by feed tube 3.Two collector tube entrance points lay respectively at the two ends of evaporator, and two collector tube exit end also lay respectively at the two ends of evaporator, the incorgruous layout of flat tube import and export.
Claims (2)
1 one kinds of incorgruous superimposed band-tube evaporators include flat tube (7), and flat tube is continuous U-shaped, are fixed with fin (5) on the flat tube; The flat tube two ends have collector tube exit end (1) and collector tube entrance point (4); It is characterized in that having two groups, to be the vertical front and back of continuous U-shaped flat tube superimposed; The collector tube exit end (1) of one group of flat tube is communicated with the collector tube exit end (4) of another group by freeing pipe (2); The collector tube entrance point (6) of one group of flat tube is communicated with the collector tube entrance point (8) of another group by feed tube (3); Two collector tube entrance points lay respectively at the two ends of evaporator, and two collector tube exit end also lay respectively at the two ends of evaporator, the incorgruous layout of flat tube import and export.
2,, it is characterized in that two groups of flat tubes are connected by fin (5) according to the described incorgruous superimposed band-tube evaporator of claim 1.
