Abstract

The utility model provides an air-conditioner evaporator which comprises an upper and a lower liquid-accumulating pipes, a plurality of flat pipes positioned between the upper and the lower liquid-accumulating pipes, a plurality of heat-dissipating fins arranged among the flat pipes, and a plurality of drainage holes formed on the heat-dissipating fins. The air-conditioner evaporator is installed in the same way as the prior parallel-flow heat exchanger and then is turned counterclockwise for 90 DEG C, that is, the liquid-accumulating pipes are positioned at the upper and the lower ends of the evaporator. Therefore, when the condensed water is generated, the water drops are discharged out of the evaporator through the drainage holes under the action of the gravity, thereby avoiding the reduction in heat-exchange efficiency due to the freezing of the evaporator.

Description

A kind of A/C evaporator
Technical field
The utility model belongs to field of air conditioning, relates in particular to a kind of evaporimeter that is applied in the air-conditioner.
Background technology
Existing domestic air conditioning generally comprises evaporimeter and these two main heat exchanger components of condenser.For evaporimeter, the most commonly adopt copper tube and fin formula heat exchanger, therefore this heat exchanger structure compactness is extensively applied in the domestic air conditioning evaporimeter.Copper tube and fin formula heat exchanger is made up of copper pipe and fin, and fin is packed on the copper pipe, and refrigerant flows in heat exchanger tube, contacts the heat exchange of finishing between air and the refrigerant with fin by cross-ventilation then.Though the utilization of copper tube and fin formula heat exchanger is extensively, its complex manufacturing, and need a large amount of copper product of cost, so production cost is higher.In addition, be not to contact fully between the fin in the finned heat exchanger and the copper pipe, certain clearance is wherein arranged, therefore to have influence on the heat exchange efficiency of whole heat exchanger.
In order to improve heat exchange efficiency, parallel-flow heat exchanger begins to be applied in the domestic air conditioning evaporimeter, existing parallel-flow evaporator as shown in fig. 1, and it mainly is made up of liquid trap 1, flat tube 2 and radiating fin 3.In heat transfer process, because the generation of condensed water is unavoidable, when radiating fin 3 forms condensed water, according to the mounting means among Fig. 1, condensed water gravitate and toward dirty, but, radiating fin 3 is to be welded between two flat tubes 2, flat tube 2 does not have special drainage measure, condensed water is subjected to can not getting rid of smoothly after stopping of flat tube 2 like this, and, so very easily cause the frosting of cryogenic condensation water because evaporimeter is in low-temperature condition in process of refrigerastion, influenced the heat exchange property of evaporimeter greatly.
Therefore, a kind of real necessity that belongs to of parallel-flow evaporator that can get rid of the heat exchanger fin condensed water of design.
The utility model content
The purpose of this utility model is to provide a kind of A/C evaporator, and it solves the problem that condensed water can't be got rid of in the existing air-conditioner evaporator.
The A/C evaporator that the utility model provides comprises up and down two liquid traps, at some flat tubes between two liquid traps up and down, be arranged at the some radiating fins between each flat tube, a plurality of osculums are set on the described radiating fin.
Described osculum is the circular row water hole.
9 circular row water holes are set on described each radiating fin.
Evenly arrange according to the mode of triplex row three row in described 9 circular row water holes.
The described distance of center circle of horizontal adjacent circular osculum that vertically reaches is from being 3mm.
The described circular row water hole water conservancy diversion angle of gradient is 45 degree.
The mounting means of the utility model A/C evaporator is that counterclockwise 90 degree are placed on existing parallel-flow heat exchanger mounting means, be the up and down two ends of liquid trap at evaporimeter, like this, when condensed water produces, the globule is discharged evaporimeter by osculum under the effect of gravity, avoid evaporimeter frosting and influence efficient.

The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
In conjunction with referring to shown in Fig. 2, Fig. 3, the evaporimeter that the utility model preferred embodiment is provided comprises up and down two liquid traps 1, at some flat tubes 2 between two liquid traps 1 up and down, be arranged at the some radiating fins 3 between each flat tube 2, it turn 90 degrees installation (as Fig. 2) counterclockwise with existing parallel-flow heat exchanger (shown in Fig. 1), and a plurality of osculums 4 (as Fig. 3) are set on radiating fin 3, condensed water can be got rid of by osculum 4.
In conjunction with referring to shown in Fig. 4, Fig. 5, in the present embodiment, osculum 4 is selected the circular hole shape of easier draining.Have 9 osculums 4 (mode according to triplex row three row is evenly arranged) on the every radiating fin 3, the distance of center circle that vertically reaches horizontal adjacent circular osculum 4 is from being L=3mm;
Fig. 6 is the schematic diagram after the a-quadrant of Fig. 5 is amplified, and as shown in Figure 5, osculum 4 has certain water conservancy diversion gradient, wherein angle of gradient α=45 degree.
The mounting means of the utility model A/C evaporator is that counterclockwise 90 degree are placed on existing parallel-flow heat exchanger mounting means, be the up and down two ends of liquid trap 1 at evaporimeter, like this, when condensed water produces, the globule enters osculum 4 along the water conservancy diversion angle of gradient, flow into one deck radiating fin 3 down along osculum 4, draining downwards in layer splashes into water receiving bowl (figure does not show) at last and compiles outside the discharge machine.
The above only is preferred embodiment of the present utility model, and in order to restriction the utility model, for example, L is not limited to 3mm, and angle of gradient α is not limited to 45 degree yet, and the shape of osculum 4 is not limited to circle yet.In sum, all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present utility model.
