Application number is disclose a kind of heat exchanger in the patent of 200580032906.0, by inserting the metallic plate of fan-folded in heat exchanging body, by alternately installing formation first and second laminar flow road, each first flow two ends are blocked by a pair comb member, are arranged on by fin in the second runner.This heat exchanger effectively can realize heat exchange, but its complex structure, first flow is platy structure, to the more difficult realization of the heat exchange of hot conditions.Application number is the casting method disclosing a kind of honeycomb heat exchanger in the patent of 201110164783.3, the casting of this honeycomb heat exchanger is according to heat exchanger large little makings framework, bushing pipe identical with honeycomb hole size for internal diameter is arranged ordering according to the arrangement mode of cold pipe and heat pipe in framework, and two of bushing pipe is fixed on tube sheet; Heat-conducting metal powder is inserted between bushing pipe; Framework is put into pot arch, is warmed up to the melting point of heat-conducting metal powder; Heat-conducting metal powder and shaping body are combined together; Cool to room temperature and namely form integral honeycomb formula component.But it is too little that the subject matter of this heat exchanger is contact area.
Utility model content
The utility model provides a kind of high efficient heat exchanging, structure is simple, workable Integral heat-exchange device.
The technical solution of the utility model is as follows:
A kind of Integral heat-exchange device, comprise the heat exchange core body of monolithic construction, this core body is made up of the straight channels of both direction.Divide some layers according to two vertical directions, the wall thickness between every layer is 1-5mm; The direction of adjacent two layers is 90 degree of angles; Every layer of some identical duct that is arranged side by side, each duct hydraulic diameter is 1-4mm.Between between duct, wall thickness is 1-2mm, and the distance of the duct distance outer edge at most edge is greater than 5mm, forms core body wall thickness.
The processing method of described Integral heat-exchange core body is as follows:
First method: with the center, duct of every layer of centre for the center of circle is radius with 1-3mm, utilizes the method every layer of deep hole machining to get through a circular duct.Again the spark cutting line of Wire EDM lathe is passed this circular duct, according to the pore passage structure of above-mentioned division, workpiece is cut, form duct.According to this method, all will get through a hole for every layer, recycling Wire EDM completes the processing in hole, thus forms an all-in-one-piece heat exchanger core body.
Second method: the mode using Wire EDM from the edge of every layer from outside to inside, cuts open a gap and forms Wire EDM line, then cut workpiece according to the pore passage structure of above-mentioned division, form duct.According to this method, every layer all will be cut a gap from the mode of edge ecto-entad Wire EDM, form Wire EDM line, recycling Wire EDM completes the processing in duct, utilize the line of cut gap of method to the face of every layer of outer wall of welding to weld, thus form an all-in-one-piece heat exchanger core body.
The Integral heat-exchange core body formed, is made up of the straight channels of both direction, and the vertical angle of both direction is 90 degree.Mutually completely cut off between upper and lower duct; Have gusset to isolate side by side between duct, but gusset is separated due to the reason of Wire EDM with the lower wall in duct, upper strata, is separated the diameter that thickness is not more than line of cut.This core body wall and outer cage welded seal.
There is the temperature difference in fluid A and fluid B, fluid A flows out from first direction through heat exchange core body, and fluid B flows out from second direction through heat exchange core body simultaneously, thus completes the heat exchange of two media.
Described stacked heat exchanger device, the material of central layer can be metal material, also can be plastics, ceramic nonmetallic.
Integral heat-exchange wall face of the present utility model is thin, and heat-exchange performance is good, and monoblock type is processed, compact conformation, between layers good airproof performance, wide market.

Detailed description of the invention
Below by embodiment and accompanying drawing, the technical solution of the utility model is described in further detail.
Integral heat-exchange core of the present utility model and fluid media (medium) flowing schematic diagram shown in Fig. 1 and Fig. 3.As shown in the figure, heat exchange core body 3 is monolithic construction, and this heat exchange core body 3 is made up of the straight channels 1 of both direction.Be divided into some layers according to two vertical directions, the wall thickness between every layer is 1-5mm; The direction of adjacent two layers is 90 degree of angles; Every layer of some identical duct that is arranged side by side, each duct hydraulic diameter is 1-4mm.Between between duct, wall thickness is 1-2mm, and the distance of the duct distance outer edge at most edge is greater than 5mm, forms core body wall thickness.
Adding man-hour, with the center, duct of every layer of centre for the center of circle, is radius with 1-3mm, utilizes the method for deep hole machining to get through a circular duct 2.Again the line of cut of Wire EDM lathe is passed this circular duct, according to the pore passage structure of above-mentioned division, workpiece is cut, form duct 1.According to this method, all will get through a circular duct 2 for every layer, recycling Wire EDM completes the processing in duct 1, thus forms all-in-one-piece heat exchanger core body 3.
Or from the edge of every layer, use the mode of Wire EDM from outside to inside, cut open a gap and form Wire EDM line 4, then according to the pore passage structure of above-mentioned division, workpiece is cut, form duct 1.According to this method, every layer all will be cut a gap from the mode of edge ecto-entad Wire EDM, form Wire EDM line 4, recycling Wire EDM completes the processing in duct 1, utilize line of cut 4 gap of method to the face of every layer of outer wall of welding to weld, thus form an all-in-one-piece heat exchanger core body.
The Integral heat-exchange core body 3 formed, completely cuts off between neighbouring duct mutually; Have gusset to isolate side by side between duct, but due to Wire EDM, gusset is separated with top wall, is separated the diameter that thickness is not more than line of cut.Flowing in the duct that fluid media (medium) enters both direction, two kinds of fluid media (medium)s, respectively in adjacent duct interflow, do not mix mutually.As Figure 1-4, the peripheral edge of this heat exchange core body 3 and casing 5 welded seal, realize the independence of the fluid media (medium) flowing of both direction.Fluid media (medium) A flows into heat exchange core body 3 by first import 6 of described casing 5, flows out through the first outlet 7.Fluid media (medium) B flows into heat exchange core body 3 via second import 8, flows out through second outlet 9.There is temperature difference between fluid media (medium) A and fluid media (medium) B, after flowing through heat exchange core body, complete heat transfer process.
Described Integral heat-exchange device, the cross section in duct 1 can be square, circular or other shapes.The hydraulic diameter size in duct 1 is between 1-4mm.
Described Integral heat-exchange device, the material of central layer can be metal material, also can be plastics, ceramic nonmetallic.
