Description
Technical field
The present invention relates in general to heat exchanger tube and heat exchanger, relates in particular to heat exchanger tube and the heat exchanger with cylindrical tubular part, and described cylindrical tubular part has a plurality of mobile change parts in each tube-like piece.Described mobile change part is paired with the chamber combination of outer surface that is attached to described cylindrical tubular part respectively.
Background technology
Heat exchanger is generally used for the system that expectation removes heat.Common basal heat interchanger is made by straight tube roughly, in described straight tube roughly, guides heat-exchange medium.Collector or manifold are typically attached to each end of pipe.These collectors and manifold serve as the receiver for heat-exchange medium.The efficiency of tubing heat exchanger be can be used in the surface area size restriction of transferring heat.In pipe cavity type heat exchanger, a plurality of tube chamber assemblies tie up between a pair of collector or manifold and extend with isolated pass, thereby form the core of heat exchanger.The heat exchange performance of heat exchanger is determined according to the total surface area being provided by described a plurality of tube chamber assemblies.
In order to increase surface area to improve heat exchange performance, common heat exchanger (such as condenser) comprises that the flat tube conventionally being formed by the tubular material with the extrusion modling of extensional surface designs, described extensional surface is provided by corrugated fin material, and described corrugated fin material is embedded between the tubular material of a pair of extrusion modling conventionally.The heat exchanger of the type generally includes flat tube, and fluid extends between described pipe through described flat tube and a plurality of corrugated fin.Fin is attached to pipe, to effectively increase the surface area of pipe, improves thus the thermal heat transfer capability of pipe.A plurality of pipes and fin can be stacking each other, leave little opening so that air can therefrom pass through.In order further to improve heat transference efficiency, can make the wall thickness of pipe thinner.Therefore, these parts are lighter in weight, and then make whole heat exchanger weight lighter.Yet this has reduced resistance to pressure, and thinner pipe more easily damages.And assembling process is because the fragile character of parts becomes complicated.In addition, the pipe of extrusion modling is easy to stop up in manufacture process, especially in the situation that carrying out brazing process.The complexity of extrusion modling process causes higher cost and higher ratio of defects.In addition, because using extruding metal process conventionally, flat tube is extruded, therefore conventionally with the material that can easily be extruded, make flat tube, thereby make the material that can be used for flat tube conventionally be limited to aluminium well known in the prior art and various aluminium alloy.
Because the powerful compressor of needs moves through heat-exchange medium the smaller opening of pipe, so the totle drilling cost of flat tube heat-exchange system is higher.On the contrary, if do not use the compressor of high power, just need extra pipe to obtain the heat exchange performance of expectation, because less pipe has obviously reduced flowing of heat-exchange medium.The increase of pipe has improved the totle drilling cost of heat-exchange system.At present, the heat exchanger of the type is for the application of the high heat-exchange capacity of needs, such as automotive air-conditioning condenser.
In another pipe type design, pipe can be the formula design of wriggling, and does not therefore need collector or manifold, crooked back and forth because pipe is serpentine, to produce similar effect.Typical case's application of the heat exchanger of the type also has evaporimeter, oil cooler and heater core except condenser.The design of this pipe type is also for the radiator of automobile.Outside automotive field, pipe type design is applied to industry oil cooler, compressor oil cooling machine and needs in other similar applications of greater efficiency heat exchanger.The formula of wriggling design is the single long tube material with single chamber substantially, for heat-exchange medium is passed to outlet from the import of the formula design heat exchanger that wriggles, has improved thus by the pressure drag of the heat-exchange medium of heat exchanger.This is unfavorable for the performance of heat exchanger, and especially, in the purposes such as evaporimeter, for example wherein, pressure drop has obviously reduced the performance of compressor.
A kind of modification of tubing heat exchanger comprises stacking flat floor.When stacking each other, these floors are formed for transmitting the chamber of heat-exchange medium.In fact, the heat exchanger of the type is substantially identical with pipe type type heat exchanger, but is differently assembled.The heat exchanger of the type is generally embodied as modern evaporimeter.
In another modification of tubing heat exchanger, a beam tube is arranged to form the heat exchanger that is commonly called in the art shell-and-tube exchanger.In shell-and-tube exchanger, a plurality of roughly straight tubes are got up by harness, leave sufficient space so that the first heat-exchange medium can be around the flows outside of each pipe between pipe, and make the second heat-exchange medium can be mobile in each pipe.Each pipe flows outside heat-exchange medium and each pipe in mobile heat-exchange medium can be heat-exchange medium same type or dissimilar.The heat exchanger of the type makes the first end of tube bank be attached to the first manifold conventionally, and makes the second end of tube bank be attached to the second manifold.Whole tube bank is enclosed in waterproof vessel conventionally.Shell-and-tube exchanger is generally used in the purposes of high pressure extremely, and conventionally adopts two kinds of heat-exchange mediums, and wherein a kind of heat-exchange medium flows in tube bank, and the second heat-exchange medium is mobile around tube bank in waterproof vessel.Shell-and-tube exchanger is conventionally also for large-scale heat-exchange device, for the commercial and industrial purposes of the large heat-exchange capacity of needs.Shell-and-tube exchanger does not all have the roughly straight tube harness of surface amplification by the inner side at pipe or outside conventionally, thereby causes limited heat exchange performance feature.This makes shell-and-tube exchanger must amplify to meet the desired heat exchange performance, thereby needs the large face that takies for object is installed.
Another modification of heat exchanger is the design of tube chamber formula, and it has the medium guiding piece embedding in chamber combination.Tube chamber formula design heat exchanger moves in the following manner: stop heat-exchange medium along streamlined flow, and by first by medium guiding piece and then force heat-exchange medium constantly to change direction in heat exchanger and produce eddy current in heat exchanger by chamber combination.When heat-exchange medium enters tube chamber formula design heat exchanger, heat-exchange medium passes through straight length along streamlined flow.Medium guiding piece is in the end of straight length.The function of medium guiding piece is that the mobile direction of heat-exchange medium is changed over to almost vertical flowing from streamlined flow roughly, heat-exchange medium is guided in the chamber portion of heat exchanger simultaneously.Chamber portion is communicated to pipeline section, and compares with pipeline section and conventionally have larger diameter.When heat-exchange medium is introduced into chamber combination, heat-exchange medium mobile follows two semicircle paths.End in semicircle path, heat-exchange medium runs into medium guiding piece again.Along with heat-exchange medium runs into medium guiding piece again, this flows along with heat-exchange medium is directed to another pipeline section of heat exchanger and reverts to roughly streamlined flow.This process repeats voluntarily in the length of tube chamber formula design heat exchanger.
