Abstract
The utility model relates to an aluminium flat pipe for the heat exchange which is used for an evaporator and a condenser. The utility model belongs to the shaping part of a job class. The utility model is characterized in that the utility model is manufactured by the aluminium or aluminium alloys. The flat pipe is separated from 4-22 holes by a vertical reinforcing rib. The contact face of the fluid in a pipe wall and a pipeline is enlarged. The heat conduction is accelerated. The utility model has the advantages of good radiating performance, light weight, low cost and high compression strength.
Description
A kind of porous heat transfer aluminium flat conduit is used for evaporimeter and condenser, belongs to the class of jobs moulding section.
At present, haulage vehicle, engineering machinery etc. are used the heat exchanger of evaporimeter and condenser, and with copper single hole flat tube, its weak point is: 1, single hole heat exchange weak effect; 2, copper material resource anxiety, weight is big; 3, compression strength is low.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and a kind of in light weight, good heat dissipation effect, cost is low, compression strength is high porous heat transfer aluminium flat conduit is provided.
The purpose of this utility model can reach by following measure: Fig. 1 is a porous heat transfer aluminium flat conduit cross-sectional view, it is characterized in that: with vertical strengthening ribs 3 flat tube is separated out 4～22 holes between two cross walls 1.Cross wall 1, perpendicular wall 2, vertical strengthening ribs thickness are 0.6～1.5mm, and material can be aluminum or aluminum alloy.As reinforcement, increased the gas of circulation in tube wall and the pipeline or the contact area of liquid, strengthened hot conduction.Radiator is the porous heat transfer aluminium flat conduit to be bent to snakelike, and the space between the tube and tube becomes fin with 0.12mm aluminium foil wrinkle, and the heat that the porous heat transfer aluminium flat conduit contains passes to fin, and fin distributes to the space again, plays the effect of enhance heat.Reinforcement is supported between two cross walls 1, has increased the compression strength of flat tube, the wide 20～100mm that can be of cross wall, and perpendicular wall height can be 5～6mm.
Of the present utility model being characterised in that: with aluminium is raw material, between two cross wall pipes reinforcement is housed.
Fig. 1 porous heat transfer aluminium flat conduit cross-sectional view
Below in conjunction with embodiment the utility model is further specified: to make wall thickness is 1.2mm, the wide 76mm of cross wall, the perpendicular high 5.4mm of wall, the heat exchange aluminium flat conduit in 10 holes is an example: the aluminium bar of aluminium ingot being cast Φ 100 * 380mm, the cast temperature of casting rod is 700 ℃, and aluminium bar is bright and clean, non-scale, no slag inclusion.Then aluminium bar is sent into extruder, must heat aluminium bar and compression tool before the extruding, the aluminium bar heating and temperature control is at 450 ℃; Temperature is grasped at 410 ℃ during the aluminium bar extruding; Compression tool also should heat in advance, and heating-up temperature is at 300 ℃, and must not be less than one hour heat time heating time.Extrusion equipment is 650 tons of fluid pressure type extruders that Tianjin forging press factory produces, recipient Φ 105 * 400mm, mold material 3cr2w8v, adopt the shunting assembling die, extrusion ratio is 39, extrusion speed 10mm/s, and extruding force is 200kg for every square centimeter, not not with lubricator, finished product cools off naturally during extruding.The extruder back cuts into the desired length of user then with 40 tons of hydraulic straightening machines, guarantees that the hole inner fluid is unimpeded, and operating pressure can reach 3Mpa.
According to product requirement, can design different moulds by different hole counts, wall thickness, wide, the perpendicular wall height of cross wall, once be squeezed into the porous heat transfer aluminium flat conduit with aluminium bar or aluminium alloy bars.The wide 22mm in general 4 holes, high 5mm, the wide 52mm in 12 holes, high 6mm, the wide 100mm in 22 holes, high 5.7mm.
The utility model compared with prior art has following advantage:
1, thermal conductive surface enlarges, and thermal diffusivity is good;
2, weight ratio copper flat heat exchange pipe alleviates 2/3rds;
3, cost is 1/2nd of a copper flat heat exchange pipe;
4, compression strength height.
