The specific embodiment
An exemplary heat exchanger of the present disclosure is by describing with reference to following Fig. 1-3.
Fig. 1 has shown a heat exchanger 10, heat exchanger 10 comprise a top branch manifold case 30, bottom branch manifold case 40 and a plurality of in the middle of branch manifold case 20, for example branch manifold casees 20 in the middle of 4 as shown in Figure 1.Also branch manifold case 20 can only arrange between top branch manifold case 30 and bottom branch manifold case 40 in the middle of.One entry port 50 and one discharge the two ends that port 60 is formed at heat exchanger 10.
As shown in Figure 2, each top branch manifold case 30, bottom branch manifold case 40 and middle branch manifold case 20 comprise a paired plate, and each paired plate has a positive plate 21 and a cloudy plate 22.Sun plate 21 and cloudy plate 22 can anyly have the thin plate of good heat conductive characteristic material to process by stainless steel, aluminium, brass, copper, bronze or other.In addition, although positive plate 21 and cloudy plate 22 are shown as the bar shaped that both ends are semicircle, other shapes can be used equally.Each positive plate 21 and cloudy plate 22 have an import 201, one by opening 202 and an outlet 203, and each piece sun plate 21 has a planar wall 211 and an outward extending compartment 212 of the extension around planar wall 211.The cloudy plate 22 of each piece has a planar wall 221 and one around the outward extending bonding part 222 of planar wall 221.Sun plate 21 and cloudy plate 22 can be by prior art as processing such as punching press, laser cutting, water torch cutting and erosions.In other structures can adopted situation, the bonding part 222 that positive plate 21 fastens cloudy plate 22 by compartment 212 covers cloudy plate 22 to form branch manifold case.All branch manifold casees 30,20,40 by all imports 201, by opening 202 with to export 203 stacking after being connected.
As shown in Figures 2 and 3, between the positive plate 21 of each top branch manifold case 30, middle branch manifold case 20 and bottom branch manifold case 40 and cloudy plate 22, be provided with semiorbicular the first guiding piece 204, the first guiding piece 204 parts around import 201.The the second annular guiding piece 205 that has and export 203 onesize openings is arranged between the positive plate 21 and cloudy plate 22 of each top branch manifold case 30 and middle branch manifold case 20, and the second guiding piece 205 is around outlet 203.The second guiding piece 205 of annular will export 203 isolates with top branch manifold case 30 and middle branch manifold case 20, and all outlets 203 are connected to form through top branch manifold case 30, middle branch manifold case 20 and bottom branch manifold case 40, are the exit passageway 200 of heat exchanger 10.A plurality of the first packing rings 206 are placed between adjacent branch manifold case and around import 201, a plurality of the second packing rings 207 are placed between adjacent branch manifold case and around passing through opening 202, and a plurality of the 3rd packing rings 208 are placed between adjacent branch manifold case and around outlet 203.The second packing ring 207 and the 3rd packing ring 208 are processed by a slice plate.If a compartment forms and extends to adjacent branch manifold case in the distribution of import 201, between adjacent branch manifold case, the first packing ring 206 can be set.If the distribution by opening 202 and outlet 203 also adopts the compartment similarly extending with import 201, the second packing ring 207 and the 3rd packing ring 208 also can.
A first unsteady flow part 209 is placed between the import 201 of first pair of adjacent branch manifold case 400.A second unsteady flow part 210 is placed on passing through between opening 202 of second pair of adjacent branch manifold case 500, second pair of branch manifold case 500 is different from first pair of branch manifold case 400, to make the first unsteady flow part 209 be offset from the second unsteady flow part 210, in heat exchanger 10, form thus sinuous stream 100, as dotted line shows.Two the 3rd guiding pieces 301 are separately positioned between the paired plate of branch manifold case, one of them the 3rd guiding piece 301 is arranged between the cloudy plate 22 and positive plate 21 of bottom branch manifold case 40, another the 3rd guiding piece 301 is arranged between the cloudy plate 22 and positive plate 21 of the middle branch manifold case 20 adjacent with bottom branch manifold case 40, guiding piece 301 parts are around outlet 203, directed 301 part around two outlets 203 be connected with outlet 305 fluids by opening 202, the outlet 305 by opening 202 is further connected with exit passageway 200.On the planar wall 221 of the cloudy plate 22 of paired plate and the planar wall 211 of positive plate 21, form, as stamped out projection 303.
Further as shown in Figure 3, heat exchanger 10 originates in the cloudy plate 22 of top branch manifold case 30.The opening 202 that passes through of the cloudy plate 22 of top branch manifold case 30 is sealed by the first sealing plate 231.Packing ring 206 ' can be by being fixed to such as welding or the mode of high temperature brazing on the opening 201 of cloudy plate 22 of top branch manifold case 30, and packing ring 208 ' can be fixed to by the mode such as welding or high temperature brazing in the outlet 203 of cloudy plate 22 of top branch manifold case 30.The first sealing plate 231 and packing ring 208 ' are processed by single piece of sheet metal, and heat exchanger 10 ends at the positive plate 21 of bottom branch manifold case 40.The import 201 of the positive plate of bottom branch manifold case 40 is by the second sealing plate 232 sealings, and the opening 202 that passes through of the positive plate of bottom branch manifold case 40 is sealed by the 3rd sealing plate 233 with outlet 203.
In actual applications, in heat exchanger 10, form a sinuous fluid flowing path 100.Fluid is flow through stream 100 enter connected import 201 of heated engine oil for example.Next step is placed on fluid the first unsteady flow part 209 guiding elongated channel 304 between the import 201 of first pair of adjacent branch manifold case 400 and enters by opening 202.Stream 100 continues to be placed on the second unsteady flow part 210 guiding elongated channel 304 that are offset with the first unsteady flow part 209 between second pair of adjacent branch manifold case 500 and arrives the import 201 being connected.Stream 100 continues through the elongated channel 304 of a middle branch manifold case 20 and bottom branch manifold case 40, to lead to the outlet 305 by opening 202 from connected import 201.Fluid finally flows into exit passageway 200, and will be by medium as water or the cooled fluid expulsion heat exchanger 10 of air at this.
The first unsteady flow part 209 is placed between the import 201 of first pair of adjacent branch manifold case 400, the second unsteady flow part 210 is placed on passing through between opening 202 of second pair of adjacent branch manifold case 500, has formed thus a relatively long sinuous stream 100 in heat exchanger 10.Long sinuous stream 100 can increase the heat exchange between heat exchanger 10 internal flows and external agency.Certainly unsteady flow part can be more than two.Heat exchanger 10 can only include branch manifold case 20 and bottom branch manifold case 40 in the middle of top branch manifold case 30, one.The first unsteady flow part 209 can be placed between top branch manifold case 30 and a middle branch manifold case 20, and the second unsteady flow part 210 can be placed between bottom branch manifold case 40 and middle branch manifold case 20.
Can make multiple change and modification to the embodiment of heat exchanger of the present invention, this is apparent for a person skilled in the art.For example, paired plate comprises two identical plates, and plate has planar wall and along the outer of planar wall, compartment is set, or paired plate comprises two identical cover plates, along the distribution between cover plate, interval box is set.It is only exemplary that described description and example should be considered to, and true scope is limited by claims and equivalent thereof.
