Abstract
The invention relates to a novel parallel flow heat exchanger with a flow separating structure. The heat exchanger comprises a pair of flow collecting pipes which is parallel to and separated from each other, and a plurality of flat pipes which are parallel to one another, wherein the flow collecting pipe on one side is used as a liquid separating pipe, and the flow collecting pipe on the other side is used as a liquid collecting pipe; the two ends of each flat pipe are respectively communicated with inner cavities of the liquid separating pipe and the liquid collecting pipe; fins are arranged among adjacent flat pipes; at least one medium inlet is formed on the wall of the liquid separating pipe; clapboards are arranged on the two sides of the medium inlet in the liquid separating pipe; a jet cavity is formed between the two clapboards; expansion cavities are formed on the two sides of the two clapboards; the span length of the jet cavity is smaller than that of the expansion cavities; and the jet cavity and the expansion cavities are communicated through overflow holes in the clapboards. The two clapboards with the overflow holes separate the liquid separating pipe into the jet cavity and the expansion cavities, so that the flow separating structure and a production process of the flow collecting pipes are greatly simplified, the requirement on a production technology is reduced, rejection rate and production cost are reduced, and the popularization and application of a product are facilitated.
Description
Technical field
The invention belongs to the parallel-flow heat exchanger technical field, specifically relate to a kind of parallel-flow heat exchanger of novel flow dividing structure.
Background technology
Parallel-flow heat exchanger is an equipment of realizing that heat transmits between cold fluid and hot fluid, is widely used in fields such as HVAC.Parallel-flow heat exchanger generally comprises two headers that are parallel to each other, and is provided with some parallel substantially heat radiating flat tubes between two headers, and soldering has the heat transmission fin between adjacent flat tube.During work, medium is pressed design direction along flat tube and is flowed between header, when flowing; Carry out heat exchange with the air of blowing over fin; In order to improve heat exchanger effectiveness, the medium every heat radiating flat tube of must uniform distribution flowing through, this just need be provided with flow dividing structure in header.In the prior art; Flow dividing structure in the header has a variety of forms; Patent " parallel flow heat exchanger of novel uniform distribution structure " (application number: 201010246554.1 such as the applicant; The applying date: 2010-08-05) with " the header structure of heat exchanger " (application number: 201010298093.2, the applying date: 2010-09-29), all be that the flow dividing structure in the header is improved.These flow dividing structures can play the effect of all joining medium, but structure is still very complicated, and are also very high to manufacturing requirements, go out waste product easily, cause production cost to be difficult to descend, and are unfavorable for applying of product.
Summary of the invention
The present invention solves above-mentioned existing in prior technology technical problem, and a kind of parallel-flow heat exchanger of novel flow dividing structure is provided.
Above-mentioned technical problem of the present invention mainly is able to solve through following technical proposals: a kind of parallel-flow heat exchanger of novel flow dividing structure; Comprise a pair of header that is parallel to each other and is separated from each other, the header of a side is done separating tube, and the header of opposite side is made collector tube; The flat tube that some two ends are communicated with and are parallel to each other with the inner chamber of separating tube and collector tube respectively; Be provided with fin between the adjacent flat tube, the tube wall of said separating tube is provided with at least one medium inlet, and the both sides of medium inlet are provided with dividing plate in separating tube; Be spray chamber between two dividing plates; Two dividing plate both sides are expansion chamber, and the span length of spray chamber is less than the span length of expansion chamber, and the spout hole on the dividing plate is communicated with spray chamber and expansion chamber.
As preferably, the span length of said spray chamber is 1～2 flat tube, and the span length of expansion chamber is 10～15 flat tubes.Can consider to become big according to actual conditions.
During use; Medium with certain pressure gets into the spray chamber of separating tube through the medium inlet, the spout hole on dividing plate gets into expansion chamber again, gets into the flat tube heat exchange at last and is cooled; Medium is after the spout hole on the dividing plate sprays the entering expansion chamber; The gas-liquid two-phase of medium mixes the generation flow-disturbing each other in expansion chamber, makes that medium gas phase and liquid-phase mixing are more even, and every flat tube all joined better effects if.The present invention intercepts into spray chamber and expansion chamber by two dividing plates that have spout hole with separating tube; The flow dividing structure and the production technology of header have been simplified greatly; And then having reduced requirement to production technology, percent defective is minimized, and has also reduced production cost; Help applying of product, so the present invention have the ingenious characteristics such as rationally of simple in structure, design.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically technical scheme of the present invention.
Embodiment: referring to Fig. 1, parallel-flow heat exchanger of the present invention comprises a pair of header that is parallel to each other and is separated from each other, and the header of a side is done separating tube 1; The header of opposite side is made collector tube; The flat tube 2 that some two ends are communicated with and are parallel to each other with the inner chamber of separating tube 1 and collector tube respectively is provided with fin 3 between the adjacent flat tube 2, and wherein the tube wall of separating tube 1 is provided with a medium inlet 8; The both sides of medium inlet 8 are provided with dividing plate 4 in separating tube; Be that 5, two dividing plate 4 both sides of spray chamber are expansion chamber 6 between two dividing plates 4, the span length of spray chamber 5 is 1～2 flat tube usually; The span length of expansion chamber 6 is 10～15 flat tubes, and the spout hole on the dividing plate 47 is communicated with spray chamber 5 and expansion chamber 6.If separating tube longer dimension flat tube number is more, consider that medium injection is not enough apart from possibility, the medium gas-liquid two-phase mixes even inadequately, and medium also can get into separating tube by demultiplexing, promptly on the tube wall of separating tube, is provided with organize medium inlets and dividing plate combinations more.
During use; Medium with certain pressure gets into the spray chamber of separating tube through the medium inlet, the spout hole on dividing plate gets into expansion chamber again, gets into the flat tube heat exchange at last and is cooled; Medium is after the spout hole on the dividing plate sprays the entering expansion chamber; The gas-liquid two-phase of medium mixes the generation flow-disturbing each other in expansion chamber, and it is more even to make the medium phase mix, and every flat tube all joined better effects if.The present invention intercepts into spray chamber and expansion chamber by two dividing plates that have spout hole with separating tube; The throttle structure and the production technology of header have been simplified greatly; And then having reduced requirement to production technology, percent defective is minimized, and has also reduced production cost; Help applying of product, so the present invention have the ingenious characteristics such as rationally of simple in structure, design.
At last, should be pointed out that above embodiment only is the more representational example of the present invention.Obviously, the invention is not restricted to the foregoing description, many distortion can also be arranged.Every foundation technical spirit of the present invention all should be thought to belong to protection scope of the present invention to any simple modification, equivalent variations and modification that above embodiment did.
