Description
Technical field
The utility model relates to coach air conditioner design and manufacturing technology field, specifically, is a kind of reservoir of the finned automotive air conditioning device of pipe.
Background technology
Along with the progress of production technology and the raising of people's living standard, the passenger vehicle of producing now has been air-conditioning vehicle nearly all.It is an essential assembly of aircondition design that refrigerant accumulator in the conventional automotive air conditioning device is considered for, and people seldom consider other problems to it except considering its amount of capacity.But liquid reservoir but may become the key of liquid refrigerant control in application practice, and it not only can affect condensing pressure and refrigerant cools degree, and usually can affect the reserves of refrigerant liquid.The structure that existing liquid reservoir adopts is (referring to Fig. 1): tank body 11 is made of by connector 14 two tank bodies, and tank body 11 is longer, and the rear and front end all is provided with supporting seat 15.What feed tube 12 generally adopted is straight tube, and the outlet of feed tube 12 is at the end of straight tube; Drain pipe 13 is the structure of front straight palintrope, and the rear end (import) of drain pipe 13 bendings is located at the bottom of tank body 11, and the front end exit of drain pipe 13 is arranged on the centre position (referring to Fig. 2) of tank body opposite side end cap.
The deficiency of existing liquid reservoir mainly is: (1) feed liquor and fluid are positioned at the two ends of reservoir, and like this, tank body 11 is difficult to do compactly, thereby has increased required installing space, and the capacity that reduces liquid reservoir is difficult to meet design requirement.(2) fluid of feed tube 12 becomes spray regime to penetrate under the effect of condensation side high pressure, and the liquid in the liquid reservoir tank is caused larger disturbance, has promoted the vaporization of tank inner refrigerant.Like this, when aircondition is full of when moving under (cold-producing medium) state in that tank body is non-, not exclusively be liquid from drain pipe 12 to the cold-producing medium the expansion valve and be in saturation state, at this moment gas-liquid mixture can cause expansion valve liquid feeding (cold-producing medium) deficiency, make the decrease in efficiency of expansion valve, thereby affect refrigeration.(3) condenser core adopted the cold flow journey to establish timing in tube-fin condenser, needed through reservoir before the super cooled sect, and the result of heteropleural turnover has required to increase the length of pipeline and the technology difficulty of pipeline processing.
The utility model content
The utility model is intended to address the above problem, a kind of reservoir that is applied to manage finned automotive air conditioning device is provided, structurally reduce length of tank, feed tube and drain pipe rationally are set and can adapt to arranging of cold flow journey pipeline, shorten length of pipe, the technology difficulty of arranging of cold flow journey pipeline was reduced; Make the fluid of feed tube less to the liquid perturbation in the liquid reservoir tank in function, thereby guarantee that expansion valve liquid feeding is complete, make liquid state that certain degree of supercooling be arranged, guarantee refrigerating efficiency.
For realizing above-mentioned purpose, the utility model has adopted following technical proposals.
Manage a kind of reservoir of finned automotive air conditioning device, contain tank body, feed tube, drain pipe and supporting seat, it is characterized in that, described tank body is made of an intermediate and tank body protecgulum and rear cover of tank, tank body adopts the structure of one-sided turnover, described feed tube and described drain pipe are welded on the same side of tank body: described feed tube is arranged on through the side on the horizontal line of axis, described drain pipe is arranged on through the side under the horizontal line of axis, and the setting position of described feed tube and described drain pipe is the same side about the central point that axis and horizontal line intersect not; A fluting that makes progress is set in the exit of described feed tube front end, and the plug of front end welding at described fluting makes described fluting form the outlet opening that perforate makes progress; Described drain pipe is a bend pipe structure, and the import of drain pipe is arranged under the horizontal line and close tank bottom by bend pipe structure.
Further, the diameter of described tank body is between 100～120mm and can adjust according to the headspace of housing, and hour, described tank body can be done shortly than the conventional design tank body of same specification on the headspace length direction, and diameter is large.
Further, described feed tube and described drain pipe are welded on the tank body protecgulum.
Optionally, described feed tube is arranged on the axis of tank body one side through 30 ° on the horizontal line of axis～60 ° of angles.
Optionally, described outlet opening is square or the rectangle perforate.
Further, described drain pipe is arranged on and comprises under the horizontal line of tank body the same side through the axis and pasting described horizontal line position up and down.
Good effect of the present utility model is:
(1) in the limited situation of installing space, the homonymy that feed tube and drain pipe are arranged on tank body has shortened the length of tank body, makes product compacter, can satisfy the installation demand that reduces the tank body volume, thereby can save the installation cost.
When (2) flowing through reservoir before condenser adopted cold flow journey design and made super cooled sect, the homonymy turnover of feed tube and drain pipe can make pipeline arrange more to simplify.
(3) outlet opening that adopts feed tube to make progress makes the injection fluid little to the stirring that the tank body inner refrigerant causes, the tank body larger with diameter of joining, like this, when cold-producing medium is in non-full state, liquid level is higher with respect to conventional tank body, make the drain pipe import be positioned at all the time the below of liquid level, the impact of feed tube outlet opening is difficult to generate bubble in tank body lower floor, make the fluid of drain pipe fully liquid, effectively prevented from containing in the feed flow of expansion valve the phenomenon of flash steam, thereby the refrigerating efficiency of system is improved, and performance is more stable.
(4) design of big bus air conditioning for automobiles is become more meticulous more, can improve the product integrated quality, save manufacturing cost.
