Abstract
The utility model discloses a flat heat exchange of heat pipe of on -vehicle air conditioner, including import pipe (1), import collector (2), export collector (3), flat pipe (4), the fin of windowing (5), correspond import pipe (1) in the import collector (2) and locate to be equipped with imported collector baffle (6), keep apart every import pipe (1) completely. Import collector (2), export collector (3) are located the heat exchanger homonymy, still include an intercommunication collector (7), set up in the heat exchanger opposite side, flat pipe (4) both sides of intercommunication collector (7) position will with intercommunication collector baffle (8) intercommunication collector (7) is separated. The utility model discloses follow the structural improvement of optimizing, through the increase of import collector baffle and intercommunication collector baffle, realized the even high purpose of heat exchange efficiency that reaches of heat exchanger reposition of redundant personnel.
Description
Technical field
The utility model relates to in-vehicle air conditioner field, particularly relates to a kind of flat pipe heat exchanger shunted for gas-liquid two-phase uniform refrigerant for automobile air conditioning system industry.
Background technology
Heat exchanger is one of critical piece of air conditioner industry refrigeration system, is a necessaries.Heat exchanger separatory inequality will cause refrigerant flow in different pipeline uneven within air-conditioning systems, in some pipelines, flow is less, cold-producing medium premature evaporation in pipeline is complete, the excessive degree of superheat is there is at tube outlet, in some pipelines, flow is too much, the degree of superheat in exit is too low even there is liquid, and these all can make evaporator heat exchange area can not get effective utilization, system are caused to having a strong impact on.
Existing flat pipe heat exchanger two ends are two collectors, after gas-liquid two-phase cold-producing medium enters heat exchanger from one end collector, shunting enters heat exchanger evaporation, again shunt again after the second flow process is converged, this kind of structure is because being affected by gravity, the cold-producing medium lower end in collector is caused to be liquid, upper end is gaseous state, and shunting effect is limited, causes heat exchange area not to be fully used.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, a kind of heat exchanger structure is provided, heat exchanger is made all to obtain good shunting effect in the first and second flow processs, to solve the problem that heat exchanger inner refrigerant mass flow discrepancy in each passage makes heat exchange area not make full use of by increasing dividing plate to collector.
For solving above technical problem, the technical scheme that the utility model adopts is: a kind of on-board air conditioner flat pipe heat exchanger, comprise inlet tube, inlet header, outlet header, flat tube, louvered fin, in described inlet header, corresponding inlet pipes is provided with inlet header dividing plate, comes completely isolated for every root inlet tube.
Further, described inlet header, outlet header are positioned at heat exchanger homonymy;
Also comprise a connection collector, be arranged at heat exchanger opposite side, the flat tube both sides of described connection collector position are communicated with collector dividing plate and are separated by described connection collector.
Further, described heat exchanger be inlet header with outlet header side higher than the inclination mounting means being communicated with collector side, be beneficial to the draining of fin.
Compared with prior art, the utility model carries out Optimal improvements from structure, by inlet header dividing plate and the increase being communicated with collector dividing plate, achieves the object that heat exchanger shunting is even and heat exchange efficiency is high.

Detailed description of the invention
Below in conjunction with embodiment, embodiment of the present utility model is further described.
Embodiment 1:
As shown in Figure 1-2, present embodiments provide a kind of on-board air conditioner flat pipe heat exchanger of single process, comprise inlet tube 1, inlet header 2, outlet header 3, flat tube 4, louvered fin 5 (for the ease of other structures of clear display, part fin is only depicted) in figure, in described inlet header 2, corresponding inlet tube 1 place is provided with inlet header dividing plate 6, comes completely isolated for every root inlet tube 1.
In this single pass system, according to the quantity of inlet tube 1 in the number of capillaries determination heat exchanger of system liquid-dividing head, in inlet header 2, keep off the both sides at inlet tube with inlet header dividing plate 6, separated completely by each root inlet tube 1, inlet header dividing plate 6 can not block flat tube 4 entrance.
Cold-producing medium in every root inlet tube 1 converges outflow heat exchanger separately through after flat pipes of heat exchanger 4 in outlet header 3.
This structure by inlet header 2 uniform refrigerant be divided into several parts, solving the lower end that the cold-producing medium in inlet header 2 occurs because of gravity effect is liquid refrigerant, and upper end is the problem of gaseous refrigerant.Take full advantage of the heat exchange area in heat exchanger, improve the heat exchange amount of heat exchanger.
Embodiment 2:
As in Figure 3-5, present embodiments provide a kind of on-board air conditioner flat pipe heat exchanger of double-flow, inlet header 2, outlet header 3 are arranged at heat exchanger homonymy by the basis of embodiment 1; Add a connection collector 7 simultaneously, be arranged at heat exchanger opposite side, flat tube 4 both sides of described connection collector 7 position are communicated with collector dividing plate 8 and are separated by described connection collector 7.
Heat exchanger be inlet header 2 with outlet header 3 side higher than the inclination mounting means being communicated with collector 7 side so that the draining of fin.
In the double-flow system of this embodiment, identical with single process in the mode at inlet header place 2, when cold-producing medium from inlet header 2 enter flat tube 4 complete first flow process enter be communicated with collector 7 time, be communicated with collector dividing plate 8 in flat tube 4 both sides connection collector 7 is separated, make the cold-producing medium of first pass enter separately the second flow process and not with shunt again after the refrigerant mixed in other flat tubes 4, completely solve the shunting problems of the second flow process, substantially increase the heat exchange area of heat exchanger, thus add the heat exchange amount of heat exchanger.
Test proves that flat pipe heat exchanger of the present utility model is compared with traditional flat pipe heat exchanger, and identical heat exchange area heat exchange amount increases 20%-40%, and heat exchange amount increases obviously.
The utility model is widely used in automobile air conditioning system industry and other air-cooled occasions needing air cooling heat exchanger.
The content that above-described embodiment is illustrated should be understood to these embodiments only for being illustrated more clearly in the utility model, and be not used in restriction scope of the present utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
