Description

A kind of heat exchanger of multi-path parallel split-flow

Technical field

The design is related to a kind of heat exchanger, especially internal heat exchanger with outside using the air-liquid flowed as medium reality Apply the heat exchanger of internal-external heat exchange.

Background technology

At present, known heat exchanger；Such as the heat exchanger of radiator type, it with a plurality of section is rectangle that it, which is, Mozzle respectively turned in parallel in room of confluxing, being connected with multiple rooms of confluxing with multi beam mozzle can be achieved fluid and turns to and fluid Into with output.It is welded with metal fin between adjacent two water conservancy diversion pipe outer wall, being the advantages of this mode can be by larger Fluid flow, shortcoming is the Fluid pressure very little that can bear, and is not suitable in mesohigh scope（0.5-3Mpa）Use.

Another representational structure is the tube coil type heat exchanger used on air-conditioning, and its structure is a plurality of circle Shape pipeline is arranged in parallel, and pipeline is welded into a fluid passage, metallic conduit outside nothing by dedicated elbow by pipe ends successively Gap string hangs multi-disc and is used to increase heat exchange area perpendicular to pipeline and the fin that is parallel to each other, and fin spacing relies on fin Controlled with the flange height on tube fit hole.The advantages of this mode is pressure-bearing height.Shortcoming is；In order to ensure enough fluids Metal tube is relatively large in diameter used in flow, and due to the laminar flow effect of tube fluid, heat can be realized rapidly by only pressing close to the fluid of tube wall Exchange, the fluid heat transfer efficiency of the thicker closer pipeline center of pipeline is lower, and the long fluid resistance of pipeline is big, and fluid flow is limited System.

The content of the invention

The purpose of the design is to provide a kind of heat exchanger of multi-path parallel split-flow, and it can not only can apply to big flow Mesohigh occasion and also can effectively overcome the laminar flow effect of internal flow to realize higher heat exchanger effectiveness.

What the purpose of the design was realized in：Replaced with the shunting of a plurality of minor diameter pipe in-parallel in air-conditioning class heat exchanger Single tube, be sequentially connected in series a fluid passage using multibeam tube and several rooms of confluxing, gapless string hangs multi-disc outside pipeline Perpendicular to pipeline and the fin that is parallel to each other.Multiple and radiating plate plane particularly also is provided with fin arranged in parallel In the small fin at 100-120 degree angle, the spacing between the height control fin of small fin is utilized.Different water conservancy diversion pipe ranges is set Degree, mozzle quantity, the length and width of fin and quantity and the quantity for the hydroecium that confluxes, can meet different heat exchange areas.

There is parallel point of big flow due to taking above-mentioned design heat exchanger is obtained radiator type heat exchangers The advantages of stream, also achieve the resistance to mesohigh of air-conditioning class heat exchanger and can effectively overcome the laminar flow effect of pipeline.Minor diameter is led Flow tube makes heat transfer efficiency very high with fin blind-mate.Compared with radiator and air-conditioning class coil heat exchanger；Same Heat-exchange capacity can be reduced significantly volume, and exchange rate can be increased substantially with hot exchange power during same volume.Therefore It is especially suitable for requiring the field that heat exchange efficiency is very high；Such as the application such as electronic system, laser system.

Embodiment

In Fig. 1；Conflux room（1）（2）, be weldingly fixed on top and conflux room pallet（3）On, two rooms of confluxing form mutually only Vertical fluid input and output cavity.Conflux room pallet（3）Bottom be provided with the mounting hole that can coordinate mozzle, see Fig. 2. Conflux room pallet up and down（3）Between be vertically installed with the more metal being parallel to each other mozzles（6）, mozzle（6）It is divided into left and right Two beam tops are respectively turned on two rooms of confluxing, and catheter lower guide passes through bottom and confluxed room pallet（3）With room of confluxing（4）Formed Cavity.The cavity can realize that fluid turns to.

Conflux room（1）、（2）Opening be buckled in the room pallet that confluxes（3）Cavity position, edge and the room pallet that confluxes（3） Sealing bottom surface welding.In room of confluxing（1）、（2）Housing upper face is respectively welded a pipe joint（8）, pipe joint endoporus is with converging Flow chamber inner chamber turns on.

Conflux room（4）With the room pallet that confluxes（3）Sealing bottom surface welding, make the room pallet that confluxes（3）With room of confluxing（4）Between The cavity of formation turns into the cavity that confluxes, and the cavity is used for the steering for realizing fluid.In mozzle（6）It is cylindrical upper by certain Interval, gapless are provided with a number of rectangular metal fin（7）, fin（7）Plane it is vertical with mozzle.

Heat-conducting fluid is filled with by the hydroecium any of the above pipe joint that confluxes, by mozzle（6）, in room of confluxing（4）Converge Another room of confluxing is flowed to after stream again, and is exported through pipe joint, this just forms the structure of U-shaped runner heat exchanger.When setting 5 Conflux room when can realize W type flow passage structures.

In the embodiment shown in fig. 4, conflux up and down room（4）Respectively with the room pallet that confluxes up and down（3）Welding, makes room of confluxing Pallet forms an independent cavity with the room of confluxing, in room of confluxing up and down（4）Housing upper face is respectively welded a pipe joint （8）, pipe joint endoporus and conflux hydroecium（4）Inner chamber turns on.
