Abstract
The utility model relates to a heterotype parallel flow condenser used for an air conditioner in an automobile. The utility model is composed of a long header pipe 1 and a short header pipe 2 which are arranged in a parallel way, and a heat radiating pipe 3 which is vertical to the long header pipe and the short header pipe. The end part of each header pipe are sealed, and the upper part of each header pipe is provided with a cooling medium inlet 5 or a cooling medium outlet 6. The outer part of the heat radiating pipe is provided with radiating fins 4 which are communicated with the header pipes. The long header pipe is arranged at one side, the short header pipe is arranged at the other side, and the long header pipe and the short header pipe are arranged in a mutually staggered way. The inner part of the long header pipe is provided with a partition plate 7 which is corresponding to the short header pipe, and the partition plate 7 can partition the long header pipe. Thus, the long header pipe and the short header pipe can form two groups of same directional flow passages, so that the larger cooling medium gas-phase region can be divided into two groups or more than two groups of parallel cooling medium flow passages with proper lengths. Thus, the liquid supercooling degree can be enlarged, the heat exchange efficiency can be enhanced, and the load of a refrigeration compressor and an automobile engine can be lightened. The air-conditioning system for the automobile can carry out the normal running under the high temperature.
Description
Affiliated technical field
The utility model relates to a kind of condenser, especially relates to a kind of special-shaped parallel flow condenser that is used for air conditioning for automobiles.
Background technology
Most widely used parallel flow condenser profile is cubic concurrent flow or serpentine condenser in automotive air-conditioning system at present, it generally is made of header and radiating tube, there is parallel radiating tube to be communicated with between two parallel headers, radiating tube is shaped on fin outward, two parallel afflux tube end sealings, on the header refrigerant import is arranged, on another root refrigerant exit is arranged, refrigerant advances, goes out from another root header after the heat radiation of radiating tube fin from a header.This kind condenser is sometimes because of reasons in structure, once short header was divided into two certain header, be staggeredly arranged, wherein have only a short header that refrigerant exit is arranged, another long header at one end has the refrigerant import, there be a dividing plate corresponding that long header is cut off in the long header, so between long header and corresponding short header, be used for the mobile porous flat pipe of fluid and have only one group of equidirectional mobile runner with short header.Through experimental verification in many ways, have only the method for one group of equidirectional mobile runner to be difficult to get a desired effect by this kind, especially in the summer of hot heat, the automobile engine effects of load is very high.Being easy to generate fault quits work compressor.Refrigerant circulation passage in porous flat pipe is bigger, among formed gas phase zone, gas-liquid two-phase district and the liquid phase region, the length ratio of liquid phase region is unreasonable, cause gas-liquid skewness weighing apparatus, make refrigerant after gas phase zone, the heat exchange of gas-liquid two-phase district, the formation liquid phase overstocks, and the heat exchange efficiency of the lower liquid phase region of refrigerant temperature is lower, caused the waste of heat exchange area, liquid phase region is long simultaneously makes the refrigerant resistance increase, these have had a strong impact on condenser to the heat exchange amount, have reduced the air-conditioning system refrigerating capacity simultaneously, have increased system exhaust pressure and power consumption.Cause the condensation effect that do not reach.
The utility model content
The purpose of this utility model, just provide a kind of special-shaped parallel flow condenser that is used for air conditioning for automobiles, its both can satisfy because of reasons in structure will long header be divided into two or more than the requirement that is staggeredly arranged, and refrigerant length ratio of liquid phase region in porous flat pipe is reasonable, the gas-liquid distributing equilibrium has improved the heat exchange efficiency of refrigerant.
For achieving the above object, special-shaped parallel flow condenser of the present utility model constitutes by the header that is arranged in parallel more than at least three with perpendicular to the radiating tube of header, and the sealing of described header end has refrigerant import or refrigerant exit on it; Described radiating tube is communicated with each header, and radiating tube is shaped on fin outward, it is characterized in that: described header is divided into long and short two classes, and long header is contained in condenser one side, and all the other short headers are contained in opposite side, and are staggeredly arranged; There is the dividing plate corresponding that long header is cut off in the described long header with short header.So long header constitutes two groups of runners in the same way with short header.
On the basis of the above, the utility model also can further be retrofited:
A) also have dividing plate will lack header in the described short header and cut off, corresponding therewith, also increasing in the long header has the dividing plate corresponding with short header that long header is cut off, and so long header constitutes four groups or above runner in the same way with short header.
B) fixedly connected with radiating tube between long header and the short header.
The beneficial effects of the utility model are: because the utility model adopts long header and short header to constitute two groups or more flow passage structure, thereby bigger refrigerant gas phase zone can be divided into the parallel refrigerant circulation passage of two groups or more flow process suitable length, refrigerant fluid interchange in each passage forms the rational gas phase zone of length ratio (precooling zone) like this, gas-liquid two-phase district (condensation segment), liquid phase region (super cooled sect), because of wherein liquid phase region length is reasonable, guaranteed that refrigerant is in gas phase zone, the gas-liquid two-phase district has the flow process of sufficient length to carry out high efficient heat exchanging, improve the heat exchange efficiency of condenser greatly, strengthened the degree of supercooling of liquid.Improved the cooling effect in the automobile, the load that has alleviated refrigerant condenser and automobile engine guarantees the normal operation of automotive air-conditioning system under megathermal climate.And have only between former long header and the corresponding short header one group in the same way the parallel flow condenser of runner compare, under the identical situation of conditions such as draught area, it is nearly 20% that the heat exchange amount has improved, and the internal flow passage resistance has reduced by 20% ~ 30%, and internal volume reduces 20%.
