Abstract
The invention discloses a heat exchanger, in particular a flat tube heat exchanger which comprises collecting tubes and flat tubes, wherein an inlet and outlet tube is arranged on each collecting tube, a plurality of minute channels are arranged in the flat tubes, a plurality of flat tubes are vertically connected between the two collecting tubes at parallel equal intervals to form fluid channels, the number of the fluid channels is two, the flat tube of one fluid channel protrudes outwards, the convex part is separately inserted in an interval of the flat tubes arranged on the other fluid channel to enable the flat tubes arranged on the two fluid channels to be superposed and tightly jointed, an aluminum foil is arranged between every two jointed flat tubes on the two fluid channels, the collecting tubes are punched with equal distances, and both ends of the plurality of flat tubes are respectively inserted in punched holes in the collecting tubes to form a whole body through welding. The invention greatly enhances the heat transfer performance and the pressure resistance of the heat exchanger, has low cost, and can be used in places with high heat transfer performance, high fluid pressure and compact space.
Description
Technical field
The present invention is a kind of heat exchanger, particularly a kind of flat tube heat exchanger.
Background technology
Heat exchanger is a kind of device that carries out power conversion through two or more temperature different fluids.Existing heat exchanger comprises shell and tube heat exchanger, heat-exchangers of the plate type or tube-in-tube heat exchanger, and the shell-tube heat exchanger volume is big, and cost is high; Plate type heat exchanger costs an arm and a leg, and manufacturing process is complicated; The double pipe heat exchanger pressure drop is big, and the heat exchange effect is undesirable.
Summary of the invention
The objective of the invention is that existing heat exchanger volume is big in order to overcome, expensive, defective that pressure drop is big, invent the flat tube heat exchanger that a plurality of flat tubes that micro-channel arranged of a kind of usefulness fit tightly.
The objective of the invention is to realize as follows: said flat tube heat exchanger, comprise header and flat tube, header is provided with imports and exports pipe, is provided with a plurality of micro-channels in the flat tube; Between two headers; Parallelly vertically be connected with many flat tubes equally spacedly; It constitutes a fluid passage, comprises two fluid passages altogether, and the flat tube on one of them fluid passage outwards protrudes; Projection is inserted in the flat tube spacing on another fluid passage, two flat tubes on the fluid passage self is superposeed fit tightly.
Said fluid passage can be plural a plurality of fluid passage, and the flat tube on these a plurality of fluid passages self superposes and fits tightly.
Between the flat tube of fitting each other on said two or more fluid passage, be provided with aluminium foil.
Said many flat tubes are through in the punching of header equal intervals, and insert respectively in the punching on the header at the flat tube two ends again, then through the fine one that is welded in.
Good effect of the present invention is following: because the heat transfer coefficient of fluid in the flat tube micro-channel is higher than conventional yardstick, so improved the heat transfer property of heat exchanger greatly; Because the flat tube bearing capacity is very high, so improved the withstand voltage properties of heat exchanger greatly; The raw material flat tube of this heat exchanger is easy to obtain, and welding method is identical with conventional continuous fine brazier, so with low cost; This heat exchanger can be used for the compact occasion in heat transfer property height, fluid pressure height and space.
Description of drawings
Fig. 1 is a structure chart of the present invention
Fig. 2 is the flat tube cross-section structure
Among the figure: 1 header, 2 flat tubes 3 are imported and exported pipe
4 micro-channels, 5 aluminium foils
The specific embodiment
Said flat tube heat exchanger comprises header 1 and flat tube 2, and header 1 is provided with imports and exports pipe 3, is provided with a plurality of micro-channels 4 in the flat tube 2; Between two headers 1; The parallel many flat tubes 2 that vertically are connected with equally spacedly; It constitutes a fluid passage, comprises two fluid passages altogether, and the flat tube 2 on one of them fluid passage outwards protrudes; Projection is inserted in the flat tube spacing on another fluid passage, two flat tubes 2 on the fluid passage self is superposeed fit tightly.
Said fluid passage can be plural a plurality of fluid passage, and the flat tube 2 on these a plurality of fluid passages self superposes and fits tightly, and realizes the heat exchange of multiple fluid.
2 of the flat tubes of fitting each other on said two or more fluid passage have been provided with aluminium foil 5.The effect of aluminium foil 5 is auxiliary welding.
Said many flat tubes 2 are through in header 1 equal intervals punching, and insert respectively in the punching on the header 1 at flat tube 2 two ends again, then through the fine one that is welded in.
During use, two fluid passages flow into two kinds of different fluids of temperature respectively, and these two kinds of fluids flow through from adjacent flat tube respectively, and the heat of high temperature fluid will be through flat tube to the cryogen transmission.Because the heat transfer coefficient of fluid in micro-channel is higher than conventional yardstick, so the heat transfer property of heat exchanger improves greatly; In addition, because the flat tube bearing capacity is very high, so the heat exchanger withstand voltage properties improves greatly.This heat exchanger can be used for the compact occasion in heat transfer property height, fluid pressure height and space.
