Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Fig. 1 is the structural representation of a kind of flat flow multimedium heat exchanger of the present utility model, and Fig. 2 is the top view of a kind of flat flow multimedium heat exchanger of the present utility model; Described heat exchanger comprises at least two flat pipe group, the first collector tube 5 and the second collector tube 6; Each described flat pipe group comprises from top to bottom the upper flat tube 1 of close contact successively, middle flat tube 2 and lower flat tube 3, wherein goes up flat tube 1 and lower flat tube 3 is first medium flow channel, and middle flat tube 2 is second medium flow channel; Formation the 3rd medium flow channels (for the pipeline that all round closure, two ends are not closed) is organized between two described flat pipe group; Each described upper flat tube 1 is all communicated with 5 with the first collector tube described in the end of the same side of lower flat tube 3, and the end of the same side of each described middle flat tube 2 is all communicated with 6 with the second collector tube described in.First collector tube at described flat pipe group two ends and the second collector tube are respectively as the import and export of medium.
Further, described upper flat tube 1 is equal with lower flat tube 3 length.The length of described upper flat tube 1 is less than the length of described middle flat tube 2.Described first collector tube 5 and the second collector tube 6 that are positioned at the same side are arranged in parallel on the length direction of described flat pipe group, and described second collector tube 6 is positioned at the outside of described first collector tube 5, described middle flat tube 2 runs through described first collector tube 5 and realizes being communicated with described second collector tube 6.
Further, multiple support column is set between adjacent two described flat pipe group, for the formation of described 3rd medium flow channels.
Further, described support column is for supporting fin 4, and end face or the ground of adjacent two described support fins 4 and described 3rd medium flow channels form triangle.
Further, described upper flat tube, middle flat tube and lower flat tube parallel contact, described first medium matter flow channel, second medium flow channel and the 3rd medium flow channels are arranged in parallel.
Further, the medium of described first medium flow channel is liquid or gas-liquid two-phase medium; The medium of described first medium flow channel is liquid or gas-liquid two-phase medium; The medium of described 3rd medium flow channels is the blending agent of gas or gas and spray liquid.
