Abstract
The utility model discloses a heat exchanger with micro -channels, micro channel flat tube bend and are the turn of U type, and the cross -section of the flat pipe that flows back is rectangle, the fin is equipped with between micro channel flat tube and the back flow, left pressure manifold and right pressure manifold are equipped with to the curved both ends of U type of microchannel radiator, the end cover is equipped with in the upper end of left and right pressure manifold and lower extreme setting, and the top of left pressure manifold is provided with the influent stream mouth, and the below of left pressure manifold is provided with outflowing port, left side pressure manifold is provided with in outflowing port's top cuts apart business turn over fluidic baffle. This technique reduces the heat exchanger with micro -channels solder joint, improves the quality and the stability of product.
Description
Technical field:
The utility model relates to a kind of micro-channel heat exchanger, is specially adapted to use on air conditioning for automobiles, domestic air conditioning and main equipment radiator.
Background technology:
At present, micro-channel heat exchanger has compact conformation, the coefficient of heat transfer is high, lightweight, the advantages such as cold-producing medium fluence abundance, at air conditioning for automobiles, domestic air conditioning, in the products such as main equipment heat radiation, be used widely, in order to ensure the abundant heat exchange of fluid, fluid just need to longer flow process make fluid and the abundant heat exchange of medium, the micro-siphunculus flat tube using in micro-channel heat exchanger is at present generally linearity, every flat tube two ends are all welded on header, by being set in header, dividing plate ensures the flow process of fluid, its shortcoming is: product solder joint is many, in two headers, all need to arrange multiple dividing plates, quality stability is poor.
Summary of the invention:
Task of the present utility model is that proposition one is simple in structure, solder joint is few, a kind of micro-channel heat exchanger of constant product quality.
The technical solution of the utility model completes as follows, a kind of micro-channel heat exchanger, it is characterized in that: micro-channel flat bending is U-shaped curved, the cross section of backflow flat tube is rectangle, between described micro-channel flat and return duct, fin is housed, left header and right header are equipped with in the U-shaped curved two ends of described microchannel heat sink, a described left side, the top and bottom of right header arrange is equipped with end cap, the top of left header is provided with influent stream mouth, the below of left header is provided with out head piece, described left header go out head piece above be provided with and cut apart the dividing plate that passes in and out fluid. the U-shaped curved of described micro-channel flat folding is even number, and the width of described backflow flat tube is consistent with described micro-channel flat width, and the circulation area in described backflow flat tube is greater than micro-channel flat.
The technical program has following effect: reduce micro-channel heat exchanger solder joint, improve quality and the stability of product.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model; Fig. 2 is micro-channel flat bending structure schematic diagram; Fig. 3 is backflow flat tube configuration schematic diagram; Fig. 4 is that flat tube and return duct pack fin structure schematic diagram into; Fig. 5 shows fluid flow direction schematic diagram.
Drawing explanation: 1, micro-channel flat, 2, backflow flat tube, 3, influent stream mouth, 4, left header, 5, fin, 6, right header, 7, go out head piece, 8, end cap, 9, dividing plate.
Detailed description of the invention:
It is curved that the micro-channel flat of the technical program is bent into two or more U, the curved two ends of U are connected with header, bending part does not need to be connected with header, fluid flows to from a side header, after micro-channel flat after bending is curved, enter opposite side header, the fluid that flows to opposite side through all micro-channel flat collects in opposite side header, then by a larger backflow flat tube of bore, fluid is flow back into again in the header of side. specific embodiment as shown in Figure 2, micro-channel flat 1 bending is U-shaped curved, U-shaped curved be even number, not only limit to 2, also can be 4 or more, the cross section of backflow flat tube 2 is rectangle, width is consistent with described micro-channel flat width, furtherly: the circulation area in described backflow flat tube is greater than micro-channel flat, circulation area in described micro-channel flat and backflow flat tube is greater than micro-channel flat, fin 5 is housed between described micro-channel flat and return duct and forms microchannel heat sink, left header 4 and right header 6 are equipped with in the U-shaped curved two ends of described microchannel heat sink, bending part does not need to be connected with header, furtherly: a described left side, the top and bottom of right header arrange is equipped with end cap 8, the top of left header 2 is provided with influent stream mouth 3, the below of left header is provided with out head piece 7, described left header go out head piece above be provided with and cut apart the dividing plate 9 that passes in and out fluid.
When work, fluid enters left header 4 through influent stream mouth 3, left header go out head piece 7 above to have dividing plate 9 to pass in and out fluid separated, the fluid entering by influent stream mouth 3 flow in right header 6 through being converted into the curved micro-channel flat of U 1 in header 4. Enter into right header 6 through all micro-channel flat 1 from left header 4 tops and converge, the fluid after converging flows back in left header 6 through backflow flat tube 2, flows out, because the fluid that has turnover in left header 4 of dividing plate 9 can not mix through going out head piece 7. Fin 4 plays auxiliary heat-exchanging effect, therefore improved quality and the stability of product.
