Description
Technical field
The utility model belongs to automobile construction technical field, is related to automobile air-conditioning evaporator, and more specifically, this practicality is new
Type is related to a kind of automobile air conditioner evaporator core assembly.
Background technology
With making rapid progress for automotive engineering, requirement of the people to automobile comfort level is higher and higher, especially air conditioning for automobiles；
At the same time auto vendor provides in fierce market competition while meeting customer need, it is desirable to provide more efficiently
The product of rate.
On-board air conditioner becomes the essential part of automobile, and evaporator is then the important component of air conditioning for automobiles, in order to carry
The heat exchange efficiency of high evaporator for motor vehicle air conditioner reduces its installation footprint, and people are in the structure of automobile air-conditioning evaporator
It is constantly improving, but current evaporator still has the shortcomings that uneven shunting, poor refrigerating efficiency.
The content of the invention
The purpose of the utility model is to overcome drawbacks described above of the prior art, provide a kind of shunting uniformly and heat exchange is imitated
The good automobile air conditioner evaporator core assembly of fruit.
In order to solve the above technical problems, the utility model adopts the following technical scheme that：
Including fin and the U-tube with multilayer arrangement being applied on the fin, it is characterised in that：On being arranged in
What the U-tube of layer was connected is gas collecting tube, and what is be connected with the U-tube for being arranged in lower floor is liquid-dividing head, is connected with the gas collecting tube
It is gas collection connecting leg, what is be connected with the liquid-dividing head is feed liquor connecting leg.
Preferably, one end of the gas collection connecting leg and feed liquor connecting leg is equipped with screwed copper sleeve.
Preferably, blanking cover is installed on the screwed copper sleeve.
Compared with prior art, the beneficial effects of the utility model are：
The utility model uses equal by gas collecting tube and liquid-dividing head between Multilayer U-shaped pipe, Multilayer U-shaped pipe in fin
Divide connection, realize and uniform divided flows are carried out to refrigerant, the refrigerant after uniform divided flows can fully evaporate in pipeline, final real
Existing high energy efficiency refrigeration.
Description of the drawings
Fig. 1 is the utility model main structure diagram；
Fig. 2 is the utility model overlooking the structure diagram；
Fig. 3 is the utility model left view structural representation.
Specific embodiment
Referring to shown in attached drawing 1- Fig. 3, a kind of automobile air conditioner evaporator core assembly including fin 1 and is applied in the wing
The U-tube 2 with multilayer arrangement on piece 1, what is be connected with the U-tube 2 for being arranged in upper strata is gas collecting tube 3, with being arranged in lower floor
U-tube 2 be connected be liquid-dividing head 4, what is be connected with the gas collecting tube 3 is gas collection connecting leg 5, is with what the liquid-dividing head 4 was connected
Feed liquor connecting leg 6.
Preferably, one end of the gas collection connecting leg 5 and feed liquor connecting leg 6 is equipped with screwed copper sleeve 7.
Preferably, blanking cover 8 is installed on the screwed copper sleeve 7.
A kind of automobile air conditioner evaporator core assembly of the utility model, fin 1 are equal using flat plate, corrugated plate or crack piece
Can, it is stamped with installing the flanging bore of the U-tube 2 on fin 1, U-tube 2 is punctured into the flanging bore and is set by tube expansion
The standby tube expansion that carries out forms A/C evaporator core, and gas collecting tube 3 is welded on A/C evaporator core top layer U-tube 2, liquid-dividing head 4
Lowest level U-tube 2 is welded on, to realize the connection with refrigeration system, what is be connected with the gas collecting tube 3 is gas collection connecting leg 5, with institute
State that liquid-dividing head 4 is connected is feed liquor connecting leg 6, the connection of feed liquor connecting leg 6 with after refrigeration system orifice union, the connection of gas collection connecting leg 5 with
In refrigeration system compressor return duct group, after being connected with refrigeration system, refrigerant is carried out by feed liquor connecting leg 6 into liquid-dividing head 4
Uniform divided flows, the refrigerant after shunting return after fin 1 is radiated after gas collecting tube 3 is collected through gas collection connecting leg 5
It flows in compressor and continues cycling through.
More than content is only to the utility model structure example and explanation, the technology people of affiliated the art
Member does various modifications or additions to described specific embodiment or substitutes in a similar way, without departing from reality
With new structure or surmount scope defined in the claims, all should belong to the protection range of the utility model.
