Abstract
The invention discloses a vehicle-mounted air conditioner flat tube heat exchanger. The vehicle-mounted air conditioner flat tube heat exchanger comprises inlet tubes (1), an inlet header (2), an outlet header (3), flat tubes (4) and window opening fins (5). The positions, corresponding to the inlet tubes (1), of the inlet header (2) are provided with inlet header partition plates (6), and therefore the inlet tubes (1) can be totally isolated. The inlet header (2) and the outlet header (3) are located on the same side of the heat exchanger. The vehicle-mounted air conditioner flat tube heat exchanger further comprises a communication header (7) which is arranged on the other side of the heat exchanger. The communication header (7) is partitioned through communication header partition plates (8) on the two sides of the position, where the communication header (7) is located, of the flat tubes (4). The vehicle-mounted air conditioner flat tube heat exchanger is structurally optimized and improved, and the purposes that flow diversion of the heat exchanger is uniform and heat exchange efficiency is high are achieved by additionally arranging the inlet header partition plates and the communication header partition plates.
Description
Technical field
The present invention relates to in-vehicle air conditioner field, particularly relate 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.
Summary of the invention
The object of the invention is to 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 solution adopted in the present invention 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 present invention 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, embodiments of the present invention are 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 invention 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 present invention 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 present invention, and be not used in and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
