Abstract
The invention relates to a micro-channel heat exchanger which comprises a micro-channel pipe, wherein two ends of the micro-channel pipe are respectively connected with a dividing collecting pipe; an access pipe is arranged on the dividing collecting pipe; and a heat exchange enhancing device is arranged on the micro-channel pipe. Under the condition of the same materials, a plenty of heat exchange surfaces can be supplied by such an acicular heat exchange enhancing device, so that the heat exchange efficiency is further increased. Besides, the flow resistance of condensate water is reduced by the acicular heat exchange enhancing device, so that the application of the micro-channel heat exchanger to an evaporator is more advantaged.
Description
Technical field
The present invention relates to the heat transmission equipment in the mechanical field application, relate in particular to a kind of micro-channel heat exchanger.
Background technology
Previous micro-channel heat exchanger is to adopt plane wave shape wave heat exchange stiffening device, after on wavy surface, increased again and windowed, improving heat exchange efficiency, but still can not reach the effect of anticipation.And original technology was unfavorable for the discharge of condensed water, big limitations the application of micro-channel heat exchanger on evaporimeter.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of novel micro-channel heat exchanger, through adopting superfine aciculiform rib, the rib diameter can replace the template rib less than 0.5mm, further increases the disturbance of heat exchange area and heat exchanging fluid, improves heat exchange efficiency.And, can promote the broader applications of micro-channel heat exchanger as evaporimeter because the space between the aciculiform much larger than the space of the sheet of windowing, makes condensed water flow out easily.
The technical solution adopted for the present invention to solve the technical problems is: a kind of micro-channel heat exchanger, comprise micro-channel tubes, and the micro-channel tubes two ends are connected with the branch header respectively, divide header to be provided with the turnover pipe, and micro-channel tubes is provided with the heat exchange stiffening device.
Further, the heat exchange stiffening device is made up of the aciculiform rib, and the aciculiform rib has 1 at least.
Further, the aciculiform rib becomes non-90 degree angles so that the discharge of condensed water perpendicular to heat-transfer surface or with heat-transfer surface.
Further, the cross sectional shape of aciculiform rib is that circle, ellipse or polygon are with further enhanced heat exchange.
Further, according to minute header and turnover pipe stream allocation requirements, divide header and turnover pipe in the same side or respectively in both sides.
Further, dividing header is the single tube or the annular closed pipeline of closed at both ends.
Further, heat exchange surface can select to increase or do not increase hydrophilic membrane as required.
The invention has the beneficial effects as follows: adopt aciculiform heat exchange stiffening device, under the situation of same material usage, more heat exchange surface will be provided, improve the coefficient of heat transfer, improve heat to increase flow disturbance.And this new design has increased the distance between the heat exchange stiffening device, has improved the flowability of condensed water, has realized the effective utilization of micro-channel heat exchanger as evaporimeter, and this describes does not influence the application of heat exchanger as other non-evaporator heat exchanger.

Among the figure: 1 micro-channel tubes 2, heat exchange stiffening device 3, divide header 4, turnover pipe.
The specific embodiment
Describe the present invention below in conjunction with the accompanying drawing and the specific embodiment: a kind of micro-channel heat exchanger as depicted in figs. 1 and 2; Comprise micro-channel tubes 1; Micro-channel tubes 1 two ends are connected with branch header 3 respectively; Divide header 3 to be provided with turnover pipe 4, micro-channel tubes 1 is provided with heat exchange stiffening device 2, so just is formed with the cavity of import and export; Heat exchange stiffening device 2 is made up of the aciculiform rib, and the aciculiform rib has 1 at least, and the arrangement of rib line is in-line arrangement or is staggered; The aciculiform rib becomes non-90 degree angles so that the discharge of condensed water perpendicular to heat-transfer surface or with heat-transfer surface; The cross sectional shape of rib line can be made into circle, polygon or oval to strengthen heat exchange according to technology; According to minute header and turnover pipe stream allocation requirements, divide header 3 and turnover pipe 4 in the same side or respectively in both sides; Dividing header 3 is can be the closed pipelines in two ends, also can be end to end closed annular pipeline; Micro-channel heat exchanger can be metal or nonmetal polymer, and heat exchange surface can select to increase or do not increase hydrophilic membrane as required, improves condensed water and flows.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
