The following technical scheme is adopted: the transverse dimension of the cross section of the liquid collection tube is 16-23mm, the longitudinal dimension thereof is 12-30mm, and the thickness of the cross section in different directions is equal. Compared with the prior art, the D-type liquid collection tube has the advantages of small size, light weight, low cost and simple structure, the welding process is simplified, and the core assembly is more reliable.
Description
Technical field
The utility model relates to a kind of collector tube that is used for air conditioning for automobiles, especially a kind of D type collector tube.
Background technology
Along with the high speed development of automobile industry, people have higher requirement in today that living standard improves energetically to vehicle safety, comfortableness and intellectuality.But increase along with intelligent equipment; Motor space is arranged must be more and more compacter, so air conditioning for automobiles shared space in the car load interior trim is more and more littler, opposite; To air conditioning for automobiles performance demands and increasingly high; Therefore must improve the efficient of each parts of air-conditioning, just can reach user's demand, the reasonability of also accomplishing cost control.
In parallel-flow heat exchangers such as existing condenser, evaporimeter, the circular collector tube liquid collecting of most of employing, the middle insertion through some straight-through flat tubes connects.Require to connect reliable; Need make flat tube insert the certain degree of depth of collector tube, just have the flat tube of certain-length like this in liquid trap inside, be unfavorable for that cold-producing medium flows into flat tube from liquid trap; Thereby produce very big resistance; Simultaneously, when using circular collector tube, cold-producing medium import and export the pore position also inconvenience obtain.
Particularly heater basically all is to be connected with flat tube by hydroecium, main leaf to realize again, because mould is complicated, so product is single and heat exchange efficiency is not fine, and spatial control is limited especially.
Summary of the invention
The purpose of the utility model is more succinct a kind of D type collector tube that takes up room little, that efficient is higher more reliably to automobile air-conditioning evaporator and heater etc. to be provided.
To achieve these goals; The utility model adopts following technical scheme: a kind of D type collector tube that is used for air conditioning for automobiles; The cross section lateral dimension of the cross section of said collector tube is 16-23mm, and longitudinal size is 12-30mm, and the wall thickness of its cross section on all directions equates; Said collector tube becomes the D type by the pultrusion of Al-alloy rod or adopts the Al-alloy plate hight D type that is welded frequently; The shape of cross section left-right symmetric of said liquid trap, surfaces externally and internally is setovered each other, and by last horizontal sides, vertical edge, following circular arc limit, adjacent edge is formed by connecting through fillet in twos; Following circular arc limit is provided with waist-shaped hole; On the last horizontal sides spacer slit is set; Cold-producing medium is imported and exported and is arranged on mouth of pipe two ends or horizontal sides or the vertical edge.
The utility model compared with prior art has the following advantages:
1, because open under collector tube on the arc surface in the flat tube hole, and following circular arc is the great circle cambered surface, so the degree of depth that flat tube inserts can reduce, and flat tube reduces in the length of liquid trap inside like this, helps cold-producing medium and flows into flat tube from liquid trap, thereby reduce flow resistance; Identical, cold-producing medium is imported and exported the pipe place can avoid the bigger situation of resistance too, and cold-producing medium imports and exports to remove and be arranged at mouth of pipe two ends and also can be arranged on horizontal sides or the vertical edge, imports and exports pipe than the cold-producing medium of circular liquid trap and moves towards more convenient.
2,, make the unit are heat exchanger effectiveness far above other pipe types, evaporimeter such as stacked, and cross section is little because to adopt the A/C evaporator and the heater of this collector tube be the concurrent flow structure; Windage is little; Therefore identical heat exchange performance lower volume is little, in light weight, and cost is low.
3, this D type collector tube is applicable to evaporimeter, condenser and heater; And the core body length and width can change with designing requirement; Particularly can replace heater the hydroecium main leaf, can replace mould molding spares such as evaporimeter flow collection pipe component; Extremely convenient, reduced mould development expense and construction cycle that change in size causes.Can adopt single D type pipe or double D type tubular construction to change thickness, applicability is strong.Simple in structure, simplified welding procedure, core assembly is more reliable, has controlled the percent defective that leakage and distortion cause; The heat exchanger that adopts D type collector tube to produce is bigger than round tube contact-making surface when on housing, installing, and the air channel sealing property is better.
