Abstract
The utility model provides a porous tubular heat exchanger which comprises a heat exchange tube (13); and the porous tubular heat exchanger is characterized in that an inner tube cavity (14) and an outer tube cavity (15) for the flowing of heat exchange mediums are coaxially arranged in the heat exchange tube (13), the outer tube cavity (15) is provided with a plurality of partition walls (16) along the radial direction of the heat exchange tube (13) so as to divide the outer tube cavity into a porous tube cavity, and the partition walls (16) convexly extend to the inside of the inner tube cavity (14). According to the utility model, two heat exchange mediums reversely flow in respective flow channels thereof, and carry out heat exchange through the wall surface of a public flow channel; and because the outer tube cavity is divided into the porous tube cavity, and the partition walls convexly extend to the inside of the inner tube cavity, the mediums in the two flow channels also can carry out heat exchange through the partition walls, thereby greatly improving the heat exchange efficiency.
Description
Technical field
The present invention relates to a kind of heat-exchange device, particularly relate to heat exchange medium carries out exchange heat through the wall of the lumen of antipriming pipe cast heat-exchange device.
Background technology
Heat exchanger is a kind of common apparatus that is widely used in industries such as chemical industry, power, medicine, metallurgy, refrigeration, light industry.Heat exchanger of a great variety, classifying by the shape of its heat-transfer area and structure can be divided into cast, template and other pattern heat exchanger.Wherein the cast heat exchanger is to use the most a kind of heat transmission equipment type.Existing cast heat exchanger can be divided into coil heat exchanger, double pipe heat exchanger, shell and tube exchanger again.And in medium and small refrigeration plant, double pipe heat exchanger is to use the most a kind of heat transmission equipment type.
Existing double pipe heat exchanger is broadly divided into two kinds of coaxial-type and multi beam tubular types by version.
The structure of coaxial-type double-tube heat exchanger such as accompanying drawing 1 and shown in Figure 4; Two different pipes of thickness are pressed the coaxial manner assembling; Coaxial sleeve 3 outside; Coaxial spiral heat-transfer pipe 1 is interior, and coaxial spiral heat-transfer pipe inner chamber forms a flow channel, and coaxial sleeve 3 internal faces, coaxial spiral heat-transfer pipe 1 outside wall surface and coaxial sleeve end socket 2 and coaxial sleeve import/export are taken over 4 and formed another flow channel.Coaxial spiral heat-transfer pipe wall is public heat exchange wall, and for increasing heat exchange area, coaxial spiral tube surface generally is processed into complicated shape, so tube wall is thicker, thermal resistance is big, cost is higher; Pipe spreader 3 is because caliber is bigger, and tube wall is also thicker.So the whole cost of heat exchanger is higher, heat exchange efficiency is lower.When heat exchanger need curve complicated shape, be difficult to guarantee that in the knee two pipes are coaxial, the fluidised form of intraductal heat exchange medium there is certain influence.
The structure of multi beam tubular type double-tube heat exchanger such as accompanying drawing 2 and shown in Figure 5; Forming a multibeam tube 9 by much thinner heat-transfer pipes is through in the thicker multibeam tube sleeve pipe 8; The internal face of the outside wall surface of multibeam tube 9 and multibeam tube sleeve pipe 8 and multibeam tube cover channel closure 6, multibeam tube sleeve pipe import/export are taken over 7 and are formed a runner; Multibeam tube 9 is taken over 5 through parallel connection and multibeam tube import/export and is formed another passage, and two kinds of heat transferring mediums carry out heat exchange through tubule bundle wall.Because the caliber of every tubule is less, tube wall can be very thin, so cost is lower; But this structure also has disadvantageous one side: one, the tube wall between the two media is very thin; Flat easily flat, leakage when curving complicated shape, when using water as medium, resistance to frost is bad during low temperature.When two, multibeam tube was parallelly connected, solder joint was many, leak detection, maintenance complicacy, and the scrappage in the process is higher; Solder joint all contacts with two kinds of heat transfer mediums, is corroded easily, influences service life.
Summary of the invention
The present invention is in order to solve the weak point that prior art exists, to provide a kind of manufacturing process simple, the high pipe heat exchanger of heat exchange efficiency that can an extrusion modling.
Technical solution problem of the present invention adopts following technical scheme:
A kind of porous pipe heat exchanger; Comprise heat exchanger tube; Its design feature is: the inner coaxial heat exchanging medium flow that is provided with of said heat exchanger tube is employed the interior tube chamber outer lumen outer with being positioned at tube chamber; Said outer lumen is provided with many partition walls along the heat exchanger tube radial direction outer lumen is separated into a porous tube chamber, and said partition wall protrudes out in the interior tube chamber; Advancing of being connected with its two ends of tube chamber in said/go out to take over one to form heat transferring medium runner one, said outer lumen and antipriming pipe end socket and enter/go out adapter two formation heat exchanging medium flow roads two; Wall of the lumen and partition wall are the public heat-transfer surface of heat transferring medium runner one and heat transferring medium runner two in said.
Design feature of the present invention also is:
Wall of the lumen thickness is 0.5～1.2mm in said.
The wall of the lumen cross section of tube chamber is ripple wire or spoke wire or gear wire or zigzag shape in said.
Said heat exchanger tube is processed for the metal or the plastics Heat Conduction Material that are prone to extrusion modling.
Compared with present technology, beneficial effect of the present invention is embodied in:
1, heat exchanger tube of the present invention inside is formed into two fluid passages by two tube chambers; Two kinds of heat transferring medium reverse flows in runner are separately carried out exchange heat through publicly-owned runner wall (wall of the lumen promptly), because outer lumen is separated wall and is separated into an antipriming pipe; And partition wall is protruded out to interior tube chamber; Make the heat-transfer surface of medium not only be confined on the interior wall of the lumen, two interior media of runner can also carry out exchange heat through partition wall, thereby improve heat exchange efficiency greatly.
2, the present invention is simple in structure; Whole heat exchanger has only a heat-transfer pipe to form; Its manufacturing process is simple, gets final product one-shot forming through manufacturing process such as extruding, and interior tube chamber cross section of fluid channel can be designed to arbitrary shape to increase heat exchange area, augmentation of heat transfer, raising structural strength.Inner-cavity structure of the present invention even interior wall of the lumen design is very thin, can not occur phenomenons such as flat flat, distortion (because complicated inner-cavity structure plays the effect of similar bend pipe plug during at pipe bending, supporting not flat flat, the distortion of book tube wall) at the pipe bending place yet.
3, the whole heat exchanger of the present invention has only a heat-transfer pipe to form, and gets final product one-shot forming through manufacturing process such as extruding, so the heat exchanger solder joint is few, convenient leak detection, maintenance.
4, the present invention draws materials conveniently, can be cheap metal such as aluminium, or common plastics such as PE, and cost is low.
