Abstract
The utility model relates to a parallel flow condenser for optimizing the flow direction of refrigerant, which is used for automobile air conditioners. The parallel flow condenser is provided with a plurality of condenser tubes in parallel arrangement, wherein pipe walls are connected with radiation fins, and both ends of each tube are respectively inserted in enclosed current-collecting tubes which are perpendicular to and are communicated with the condenser tubes. The inner part of each current-collecting tube is provided with a plurality of partition boards by which the condenser tubes and the current-collecting tubes form a bidirectional liquid path, and a refrigerant inlet is arranged at the middle section of one of the current-collecting pipes and communicated with the condenser tube in the middle. The part of the other current-collecting tube, which is communicated with the condenser tube at the tail end of the bidirectional liquid path, is provided with a refrigerant flow-passing opening that is connected with a liquid storage drying cylinder, and a refrigerant outlet is connected to the liquid storage drying cylinder. The utility model solves the problem the maximum flow region of a blower fan does not correspond to the highest temperature region of the condenser, and the distribution of a flowing refrigerant temperature field is exactly coincident with that of the airflow intensity of the blower fan. Consequently, the quantity of heat exchange is maximumly obtained under the condition that the energy is not increased.
Description
One. technical field
The utility model relates to the air conditioning for automobiles device, parallel flow condenser especially wherein.
Two. background technology
Parallel flow condenser in the air conditioning for automobiles, thus be to make the device that in its process of flowing through, makes refrigerant cools through the high-temperature high-pressure refrigerant of compressor compresses by its outer wall and air generation heat exchange.It has some condenser pipes that are arranged in parallel and perpendicular to their two ends and the header that communicates with it, is provided with in the header cold-producing medium to be turned back flow to the dividing plate of outlet in condenser.The cooling of condenser is normally adopted blower fan to force that air is flow through it and is taken away heat and realize.Because the restriction of interior space position, blower fan faces the middle part of condenser.That is to say, force the flow maximum of air at the condenser middle part.
Existing automobile air conditioner parallel flow condenser, the setting of its refrigerant inlet 1 and dividing plate 2 makes cold-producing medium form the unidirectional flow direction of turning back, (arrow is represented cold-producing medium) as shown in Figure 3, just the high temperature refrigerant that flows into concentrates on one side of condenser, forms from one side to the gradually low Temperature Distribution of another side.Obviously, in blower fan maximum stream flow zone, pairing is not the temperature highest region territory of condenser.This makes the temperature difference of cold-producing medium and air fail to reach maximum, thereby the thermal driving force that is produced makes condenser heat exchange amount not high not for maximum.In addition, liquid storage drying 6 is connected on the refrigerant outlet, might can't guarantee under special circumstances from the degree of supercooling of the cold-producing medium of liquid storage drying outflow.
Three. summary of the invention
The purpose of this utility model is that the refrigerant flow direction that existing automobile air conditioner parallel flow condenser sets is improved, and makes its high-temperature part concentrate on the zone at blower fan maximum stream flow place, to obtain maximum heat exchange amount.
Another purpose of the present utility model is to flow out after making the return condensed pipe of cold-producing medium that has passed through the liquid storage drying, to guarantee the degree of supercooling of cold-producing medium.
The technical scheme that realizes above-mentioned purpose is, with the vertical header that communicates in parallel condenser two ends in, several piece respectively is set makes required condenser pipe and header form the dividing plate on bidirectional shunt liquid road, the stage casing that refrigerant inlet is arranged at a header communicates with the middle part condenser pipe, leave cold-producing medium at the condenser pipe place of communicating with two-way liquid road end of another header and cross head piece, crossing head piece place connection liquid storage drying.
For guaranteeing the degree of supercooling of cold-producing medium, between liquid storage drying and continuous header, the place, condenser pipe place outside two-way liquid road is provided with cold-producing medium again and crosses head piece, on the header at this refrigerant inlet place, place refrigerant outlet is set.
Cold-producing medium flows into from the import in header stage casing, sees Fig. 4 (arrow is represented cold-producing medium), and under pressure promoted, set dividing plate made it flow to both sides along the liquid road that is divided into, and entered the liquid storage drying after shunting is turned back.Like this, the cold-producing medium of maximum temperature just in time is in the condenser middle part of blower fan forced draft maximum, and the distribution of the refrigerant temperature field in flowing also just in time matches with the distribution of fan airflow intensity.Thereby, under the situation that does not increase the energy, obtained the heat exchange amount to greatest extent.
When refrigerant outlet being changed on the header at refrigerant inlet place, and the condenser pipe place outside two-way liquid road be between liquid storage drying and the continuous header cold-producing medium is set again and crosses head piece after, flow to the cold-producing medium of liquid storage drying from two-way liquid road, can turn back to condenser pipe through flowing out after the cooling once more from the head piece of crossing that leads to outlet, like this, just guaranteed the degree of supercooling of cold-producing medium.
The utility model makes the structure of parallel flow condenser more reasonable, thereby the refrigeration performance of air conditioning for automobiles is improved reliably by above-mentioned improvement.
