Abstract
The utility model discloses an improved aluminum extruding thin-wall flat tube, wherein an aluminum rod is heated and then is subjected to extrusion molding. The flat tube is characterized in that a plurality of mutually isolated and parallel cold-hot preparation channels are arranged inside the flat tube. The cold-hot preparation channels extend along the length direction of the flat tube. The upper and lower surfaces of each cold-hot preparation channel are provided with a plurality of convex teeth arranged at intervals. The improved aluminum extruding thin-wall flat tube can replace a traditional electrolytic copper tube so as to effectively reduce the energy consumption, lower the environmental pollution and improve the effective utilization of resources.
Description
Technical field
The utility model is about a kind of aluminium section; Particularly a kind of modified form aluminium-made extrusion slender flat tube that is used to assemble cool-heat-exchanger; This flat tube can be assembled into cool-heat-exchanger by the random length intercepting as required; And easy to assembly, radiance is good, makes it reach the purpose that promotes hot transfer efficiency.
Background technology
At present, the cold and hot preparation passage of cool-heat-exchanger adopts circular electrolysis copper pipe (proportion is 8.9) mostly, but the cost that is to use the cathode copper pipe is than higher, and the heat exchanger weight of making is also heavy, and a large amount of use copper has caused the scarcity of copper resource.The electrolysis copper pipe needs to consume more energy in manufacture process in addition, and environmental pollution is also heavy, makes resource can not get effective utilization.
In addition; The cool-heat-exchanger that uses at present, the heat exchanger special-purpose like known freezer, the iron comb cooling heat exchange that is roughly a hollow is with (it is shaped as circle); The material of this iron comb is generally phosphorus content below 0.25%, and tensile strength is 38kg/cm
2, and 31-45Kcal/m ℃ of hr of its pyroconductivity.After permanent the use, has the shortcoming of the low difference of pyroconductivity.
China is the very abundant country of bauxite resource in the world, and under the promotion of original national industrial policies, the aluminium ingot of annual outlet has tons up to a million.Because the thermal conductivity values of aluminium is preferable, so the cold and hot preparation passage of at present general cool-heat-exchanger begins to adopt aluminium to make.
Making of aluminium aspect the heat-exchange tube; The manufacturing approach that is the disclosed flat heat exchange tubes of CN1153041C just like Chinese utility model patent notification number just discloses a kind of flat aluminum heat exchange tube that adopts this method to make; But the structure more complicated of this flat aluminum heat exchange tube needs special-purpose milling train ability roll forming.
Be the disclosed heat exchanger of CN2762029Y also just like Chinese utility model patent notification number; This heat exchanger is a polygonal body with the direct extrusion modling of aluminum pipe, and this polygonal body then includes the extension plate body that a long straight hollow circular tube and plural pieces are molded over the hollow circular tube outer rim.But this aluminum pipe exists the combination difficulty, is difficult to be designed to the compact efficient cool-heat-exchanger.
At present the flat tube used of the heat exchanger of some aluminium matter generally has following several kinds in addition; A kind of is the high-frequency welding water pipe, and this high-frequency welding water pipe is applicable to full aluminium welding type water tank of automobile-use or warm braw core body water pipe, and it is to be smelted into the aluminium blank through aluminium ingot; Through being rolled into aluminium sheet; Pass through cold rolling one-tenth aluminium foil again, aluminium foil becomes the seam pipe is arranged through mould molding, has the seam pipe to process flat tube through high-frequency welding, after flattening.
Because the production of aluminium foil at present is specialized, add that present ratio-frequency welding tubulation production efficiency is high, this flat tube is large-scale application.But owing to receive structure and production technology prevention, be actually a seamed pipe, therefore can only be used for the product development under the environment under low pressure, like full aluminium welding type water tank of automobile-use or warm braw core body water pipe like this flat tube.
Another kind is the Type B water pipe, also is to be only applicable to full aluminium welding type water tank of automobile-use or full aluminium welded type warm braw core body, and it is the Type B water pipe that seam is arranged through mould molding with aluminium foil.But, also can only be used for the product development under the environment under low pressure owing to receive structure and production technology prevention.
The band internal tooth flat tube that also has a kind of HFC134a of use refrigerant heat exchanger, this flat tube are to pass through the half-formed flat tube of mould with aluminium foil, and the half-formed flat tube of the soldering flux of annotating again is inboard, assembles half-formed flat tube and internal gear then, at last through mould molding band internal tooth flat tube.But this flat tube configuration is complicated, and soldering point is wide, and quality stability requires high, and other structures are higher relatively relatively for the product hot property, and the cost control difficulty is bigger, and the product application surface is narrow.
Though in recent years, also have some flat tubes that adopt the extrusion process moulding to occur, the body wall thickness of these flat tubes generally can only be accomplished 0.45mm.
The utility model content
The utility model technical problem to be solved be to provide a kind of environment-friendly type, high heat exchange efficiency, small size, tube wall less than below the 0.45mm, the modified form aluminium-made extrusion slender flat tube that is used to assemble cool-heat-exchanger of lightweight and ultralow input.This flat tube can be assembled into cool-heat-exchanger by the random length intercepting as required, and easy to assembly, radiance is good, makes it reach the purpose that promotes hot transfer efficiency.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of modified form aluminium-made extrusion slender flat tube adopts aluminium bar extrusion modling after heating, and it is characterized in that, is provided with some mutual isolation and parallel cold and hot preparation passage in the said flat tube; Said cold and hot preparation passage extends along the length direction of flat tube, on the above and below of each cold and hot preparation passage, is arranged at intervals with some lobes.
The wall thickness of said flat tube is 0.15mm.
The utility model compared with prior art has following advantage:
The utility model can substitute traditional electrolysis copper pipe, thereby cuts down the consumption of energy effectively, the pollution of environment and improve the resources effective utilization.Have with its development product to alleviate product weight and raw-material consumption greatly, more can design the environment-friendly type of the high heat exchanger efficiency of full aluminium welded type, high heat exchange efficiency, small size, lightweight and ultralow input get final product seriation, in, the energy-efficient compact product of small lot batch manufacture; Simultaneously also be to solve the preferred material that alternative chlorofluoro carbon is promoted the use of, and for adopting CO from now on
2Deng cold-producing medium the support on the material is provided.In the recovery and reuse to the full aluminium welded type cool-heat-exchanger product scrapped, its recovery utilization rate can reach 100%, and it is low to have a cost recovery, and industry is utilized advantages such as wide.The utility model can be used for different cool-heat-exchanger preparations, like cooling water, cold oil, fluorine Lyons preparation, HFC134a preparation or the like.Can generally be applicable on the cool-heat-exchanger in automobile, civilian air-conditioning, automatic vending machine, aviation, military affairs and the various equipment.Like water tank, warm braw core body, oil cooling gas, evaporator core, computer radiator, the ventilation of domestic air conditioning heat, automatic vending machine radiator etc.
