The feature is that it comprises hollow level header that the refrigerant can flow through; several refrigerant tubes insert in the level header, so it has the discharge sump that can discharge the condensed water, and it can distribute the refrigerant that flow in the level header. Pins are fixed among the vertical refrigerant tubes.
Description
Technical field
The present invention relates to the arm structure of a kind of ultra-fine pipeline (micro channel) heat exchanger (Micro Channel HeatExchanger), it can be discharged the condensed water that condenses in wire surface smoothly.
Background technology
Fig. 1 is the side view of the outward appearance of heat exchanger, and Fig. 2 is the exploded view of respectively forming structure of heat exchanger, and Fig. 3 is the profile of the arm among Fig. 2.
Can learn that existing heat exchanger is by constituting with the lower part with reference to above-mentioned accompanying drawing, that is: be positioned at upper header 2 corresponding to the top of lower header 1; Several arms 3 between above-mentioned upper header 2 and lower header 1; Be formed on the pin 6 between above-mentioned each arm 3.In general, in order to improve heat exchanger effectiveness, the pin of sheet material shape is housed on the outer surface that the arm that refrigeration machine flows through is arranged of heat exchanger, can realizes heat exchange to greatest extent by this structure.Above-mentioned lower header 1 cylindrical shape, its inside is hollow, a side that has constituted the outer peripheral portion of its outward appearance has formed several and has been used for inserting and the fixing header aperture 4 of arm 3, and these header aperture 4 along the length direction of lower header 1 at a distance of identical distance.
Have the shape identical with upper header 2 that above-mentioned lower header 1 is positioned at its top accordingly here, with above-mentioned lower header 1.Above-mentioned each arm 3 is separately fixed in above-mentioned each header aperture 4 along the two ends of its length direction, thereby above-mentioned each arm 3 is arranged side by side along the length direction of collector 1,2.
The face that moving air couples together the axis on the length direction of two collectors 1,2 relatively keeps certain ground, angle of inclination to flow, thereby air can flow through the gap of each arm 3 and two collectors 1,2.Above-mentioned arm 3 has certain length, thickness and width, wherein length is meant its distance between the two ends on two collectors 1,2 of being fixed on, thickness be meant its with the flow direction of moving air keep distance on the vertical direction, width be meant it with the direction of the flow direction keeping parallelism of moving air on distance.Above-mentioned arm 3 is at right angles tetragonal tabular, and it has the width and the very thin thickness that can be inserted in two collectors 1,2, and its inside has formed the pipeline (channel) 5 of several hollows.
In addition, above-mentioned each arm 3 is being fixed on two collectors 1,2 with the mode of the flow direction keeping parallelism of moving air on the width with each arm 3.Several pipelines 5 that form on above-mentioned each arm 3 have small sectional area on the direction vertical with the length direction of arm 3, length direction along arm 3 then has certain length, and they are arranged in proper order along the flow direction of moving air.
Be fixed on two collectors 1,2 owing to have the both-side ends of the arm 3 of said structure, thereby above-mentioned arm 3 is connected with the hollow spaces that form in collector 1,2 inside.And, can make the space that moving air flows through and a plurality of pins 6 have been installed in order to form in the gap of above-mentioned each arm 3.Be above-mentioned a plurality of pin 6 owing to be the tabular of very thin thickness, so be installed between each arm 3 with can being bent into several " it " fonts.Though above-mentioned pin 6 can fixedly mount with multiple shape, in general preferably its formed space can make the flow impedance of moving air reach minimum.
Fig. 4 is the side view of installment state of the pin of prior art.
As shown in Figure 4, in the ultra-fine pipeline thermal interchanger that adopts prior art, the pin 6 that is installed between each arm 3 begins till the lower header 1 from upper header 2, it is certain at interval, the condensed water 7 that forms on each pin 6 can compile downwards, and particularly all condensed waters 7 can assemble and be stuck in pin 6 places of below at last.
The moving air in gap that flows through pin 6 this moment is when the pin 6 that flows through near upper header 2, owing to can not produce special flow impedance, so the heat exchange meeting between moving air and the pin 6 realizes smoothly.But the moving air that flows through the pin 6 of close lower header 1 can be subjected to the effect of king-sized flow impedance, and this is to be stuck in this because the periphery of the pin 6 of close lower header 1 has condensed water to flow down and assemble from top, therefore can produce bigger flow impedance.Can there be following problem in this case, that is: because the increase of flow impedance can make that the heat exchange between moving air and the pin 6 can not effectively be carried out, therefore can makes the heat exchange performance variation.
Summary of the invention
The present invention designs in order to solve aforesaid problem, and purpose is by forming condensation gutter on the arm of ultra-fine channel heat-exchanging, thereby the condensed water that will condense in wire surface is successfully discharged.
The heat exchanger that possesses rhone provided by the invention is characterized in that, comprises with lower member constituting: the level header of hollow can make cold-producing medium flow through; Several vertical refrigerant pipes are inserted in the above-mentioned level header, possess the rhone that condensed water can be discharged, and can make the cold-producing medium that flows in above-mentioned level header obtain distributing; Pin is installed between the above-mentioned vertical refrigerant pipe.
Adopt the heat exchanger that possesses rhone of the present invention can reach following effect: can make the condensed water that flows down from the top of refrigerant pipe more successfully be discharged to the outside.
The present invention another effect that can reach be can reduce under the effect of fan and the atmospheric pressure lost of flow air, and can prevent that heat conduction amount from reducing.

The specific embodiment
With reference to the accompanying drawings to adopting the embodiment that possesses the heat exchanger of rhone of the present invention to be described in detail.
Fig. 5 is the side view of the outward appearance of the arm that possesses rhone of the present invention, and Fig. 6 is the view of the discharge state of condensed water in the heat exchanger of the present invention.
As shown in the figure, adopt the arm 3a of heat exchanger of the present invention that arm rhone 3b is set on the downstream position of air-flow direction, above-mentioned arm rhone 3b is the structure with certain depth that forms on the surface of above-mentioned arm 3a, and it forms along the length direction of above-mentioned arm 3a.Said structure can play following effect: the lip-deep condensed water 7 that condenses in above-mentioned pin 6 is flowed down along gravity direction along above-mentioned arm rhone 3b.
That is to say, can move and assemble to the rear of above-mentioned pin 6 under the effect of the impedance of moving air at the condensed water of the surface condensation of above-mentioned pin 6, if it is big that the particle of above-mentioned condensed water 7 becomes gradually, and it is big to the lip-deep degree that can't remain in above-mentioned pin 6, these condensed waters 7 will flow down along the surface of above-mentioned arm 3a so, this moment, above-mentioned condensed water 7 can form the passage of oneself, thereby discharges at an easy rate under the effect of the power of above-mentioned moving air.
