Abstract
The utility model discloses a kind of reducing flat tube for micro-channel heat exchanger, micro-channel heat exchanger also comprises upper hose, downcomer, the first header, the second header and outer fin.First header is communicated with the second header by some pieces of reducing flat tubes, and outer fin is fixedly connected between two pieces of adjacent reducing flat tubes.Be arranged with some fluid passages in parallel in reducing flat tube, the cross-sectional area of fluid passage successively from large to small.The side that fluid passage cross-sectional area is larger is all arranged on the windward side of micro-channel heat exchanger, the cross-sectional area of the fluid passage in reducing flat tube along flat tube outside cry-fluid flow direction from large to small, in same time, micro-channel heat exchanger is that the heat that the fluid in fluid passage is taken away is more, and heat exchange efficiency is larger.
Description
Technical field
The utility model belongs to the technical field of heat exchange heat abstractor, specifically, relates to a kind of reducing flat tube for micro-channel heat exchanger.
Background technology
In theory, when there is not extraneous heat trnasfer, the heat dissipation capacity in the different fluid passage same time in same cross section is consistent; In fact, due to the existence of external fluid, the heat dissipation capacity in the different runners same time in same cross section is inconsistent.When cryogen flows to opposite side from flat tube side, heat up due to cryogen heat absorption, the high temperature fluid simultaneously in flat tube is lowered the temperature due to heat radiation.On same cross section, due to cryogen and flat tube Contact, cryogen temperature is minimum, and the fluid temperature (F.T.) in flat tube is the highest, and therefore the temperature difference of the two is maximum, and heat exchange amount is this moment maximum.Along with cryogen is along the flowing of cross-wise direction, temperature raises, and the temperature difference also diminishes, and heat exchange amount reduces.Therefore, the flat tube that current fluid passageway width is identical does not meet the Changing Pattern of fluid heat transfer amount.
Utility model content
For deficiency above-mentioned in prior art, the purpose of this utility model is to provide a kind of reducing flat tube for micro-channel heat exchanger, and this device has the higher feature of heat exchange efficiency.
In order to achieve the above object, the solution that the utility model adopts is: a kind of reducing flat tube for micro-channel heat exchanger, micro-channel heat exchanger also comprises upper hose, downcomer, the first header, the second header and outer fin, first header is communicated with the second header by some pieces of reducing flat tubes, and outer fin is fixedly connected between two pieces of adjacent reducing flat tubes; Described reducing flat tube is the stripe board of hollow, is arranged with some fluid passages in parallel in reducing flat tube, and the cross-sectional area of fluid passage successively from large to small.
Further, fluid passage is provided with internal tooth.
Further, formed in the stripe board that fluid passage is fixedly connected on hollow by pitches inner fin.
Preferably, be fixedly connected with partition panel in the first header, the first header is divided into forebay and lower water section by partition panel, upper hose and forebay conducting, downcomer and the conducting of lower water section.
The beneficial effects of the utility model are, the cross-sectional area of the fluid passage in reducing flat tube along flat tube outside cry-fluid flow direction from large to small, meet the Changing Pattern of fluid heat transfer amount, then in same time, micro-channel heat exchanger is that the heat that the fluid in fluid passage is taken away is more, and heat exchange efficiency is larger.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
The utility model provides a kind of reducing flat tube for micro-channel heat exchanger, as shown in Figures 1 and 2, micro-channel heat exchanger also comprises upper hose 1, downcomer 2, first header 3, second header 4 and outer fin 5, first header 3 is communicated with the second header 4 by some pieces of reducing flat tubes 7, and outer fin 5 is fixedly connected between two pieces of adjacent reducing flat tubes 7.Reducing flat tube 7 is the stripe board of hollow, is arranged with some fluid passages 8 in reducing flat tube 7 in parallel, and the cross-sectional area of fluid passage 8 successively from large to small.The side that fluid passage 8 cross-sectional area is larger is all arranged on the windward side of micro-channel heat exchanger, formed fluid passage 8 cross-sectional area along flat tube outside cry-fluid flow direction from large to small, meet the Changing Pattern of fluid heat transfer amount, then in same time, micro-channel heat exchanger is that the heat that fluid passage inner fluid is taken away is more, and heat exchange efficiency increases.
As shown in Figure 3, the cross section of fluid passage 8 is set to rectangle; As shown in Figure 4, internal tooth 81 is provided with in fluid passage 8.As shown in Figure 5, formed in the stripe board that fluid passage 8 also can be fixedly connected on hollow by pitches inner fin 9.
As shown in Figure 1, be fixedly connected with partition panel 6 in the first header 3, the first header 3 is divided into forebay 31 and lower water section 32 by partition panel 6, upper hose 1 and forebay 31 conducting, downcomer 2 and the conducting of lower water section 32.Cold-producing medium enters the forebay 31 of the first header 3 from upper hose 1, enter the first half reducing flat tube 7 again, after the cryogen heat exchange of reducing flat tube 7 outside, then the second header 4 is flowed to, cold-producing medium in second header 4 continues the reducing flat tube 7 flowing to the latter half, finally flows out from the downcomer 2 be communicated with of lower water section 32.
