Abstract
The utility model relates to a circular microchannel heat-exchange aluminum member extrusion die. The extrusion die comprises a front die core, a rear die core, channel columns and an intermediate die core, wherein during production, the rear end of the intermediate die core is placed at a through hole in a groove of the rear die core, then, the front die core and the rear die core are arranged in a matched manner, then, the shape of a circular microchannel heat-exchange aluminum member is formed by the intermediate die core, the channel columns and a through hole in the front die core, liquid aluminum flows into the extrusion die from a channel in the rear end of the intermediate die core, and then, the circular microchannel heat-exchange aluminum member is extruded from the front end of the front die core. The extrusion die has the advantages that the continuity of microchannel heat-exchange aluminum member production can be well guaranteed, and during the extrusion production of relatively-small-size microchannels, the integrity of the relatively-small-size microchannels can be very conveniently controlled through adjusting the size of the channel columns; the extrusion die is simple in structure, low in cost and convenient to use.
Description
Technical field
The utility model relates to heat transmission equipment production field, and specifically circular micro channel heat exchange aluminum component extrusion die, is applicable to produce micro channel heat exchange aluminum component.
Background technology
Heat exchanger (being also called heat exchanger or heat-exchange apparatus) is for making heat be delivered to cold fluid from hot fluid, to meet the device of technological requirement of regulation, is convection heat transfer' heat-transfer by convection and heat conducting a kind of commercial Application.Heat exchanger is the common apparatus of chemical industry, oil, power, food and other many industrial departments, occupies aborning critical role.In Chemical Manufacture, heat exchanger can be used as heater, cooler, condenser, evaporimeter and reboiler etc., applies more extensive.Heat exchanger kind is a lot, but substantially can divide three major types according to the principle of cold and hot fluid exchange heat and mode: dividing wall type, hybrid and heat accumulating type.In three class heat exchangers, dividing wall type heat exchanger application at most.The type of dividing wall type heat exchanger.
Microchannel, also referred to as micro-channel heat exchanger, is exactly the heat exchanger of passage equivalent diameter at 1 0-1000 μ m.In the flat tube of this heat exchanger, there are tens of trickle runners, are connected at two ends and the circular collector of flat tube.Dividing plate is set in collector, heat exchanger runner is separated into several flow processs.Microchannel aluminium flat conduit (claiming again " concurrent flow aluminium flat conduit ") is that one adopts refining aluminium bar, sprays zinc preservative treatment by hot extrusion, through surface; thin-walled porous flat tubular material; be mainly used in the air-conditioning system of various cryogens; as the pipeline parts of carrying novel environment-friendly refrigerant, the novel environment friendly system of employing is the critical material of concurrent flow of new generation microchannel air-condition heat exchanger.
Because wall thickness between microchannel aluminum component internal holes and hole is thinner, therefore in the time using extrusion die to produce, than the situation that is easier to occur that Kong Yukong communicates, particularly in the time producing circular micro channel heat exchange aluminum component, also there is no a kind of extrusion die that is specifically designed to circular micro channel heat exchange aluminum component of simple in structure, convenience and high-efficiency at present.
Utility model content
The utility model is just for above technical problem, and a kind of extrusion die that is specifically designed to circular micro channel heat exchange aluminum component of simple in structure, convenience and high-efficiency is provided.
The utility model is achieved through the following technical solutions:
Circular micro channel heat exchange aluminum component extrusion die, comprise front core rod, rear core rod, channel post, middle core rod, it is characterized in that front core rod, rear core rod, middle core rod coupling arranges, front mould in-core is provided with manhole, rear mold in-core is provided with groove, on groove, be provided with multiple channel post, channel post is radial arrangement, the groove middle part of rear mold in-core is provided with through hole, middle die core back end is back taper platform, middle die core back end middle part external diameter equates with the through hole internal diameter at rear mold in-core groove middle part, middle core rod is arranged in the through hole at groove middle part of rear mold in-core, middle die core back end is provided with multiple tracks passage, front core rod, when rear core rod coupling arranges, channel post on rear core rod and middle core rod stretch in the through hole of front mould in-core.The passage of middle die core back end is even number bar, and in edge, core rod axis direction is symmetrical.The passage of middle die core back end is odd number bar, and in edge, core rod axis direction is radial arrangement.The channel post of rear mold in-core is even number bar.
In production, middle die core back end is put into the through hole of rear core rod groove, again by front core rod, rear core rod coupling arranges, now, middle core rod, channel post is combined with the through hole of front mould in-core and is surrounded the shape of circular micro channel heat exchange aluminum component, liquid aluminium is interior the inflow in extrusion die of passage of die core back end therefrom, in the past die core front end is extruded circular micro channel heat exchange aluminum component again, the utility model can ensure the continuity that micro channel heat exchange aluminum component is produced preferably, carrying out in the extrusion process of reduced size microchannel, can be by regulating the size of channel post, control easily the integrity degree of the microchannel of reduced size.
The utility model is simple in structure, with low cost, easy to use.
