The utility model content
The purpose of this utility model is the deficiency that overcomes prior art products, provide a kind of simple in structure, heat exchange area is big, heat exchange efficiency is high, and the low plate type heat interchanger of use cost.
The utility model is achieved through the following technical solutions technical goal.
Plate type heat interchanger, it comprises bilateral lid, left flange, housing, dividing plate, right flange, bottom and bundle pipes.Its improvements are: the axially even 2.0～3.5mm at interval of the heat exchanger tube outer wall in the described bundle pipes wears the conducting strip of 0.12～0.20mm thin-slab structure.Described conducting strip axially is the lotus root sheet, and the plate face is bent into wavy, and the plate face is provided with the hole of matching with heat exchanger tube in the bundle pipes, and conducting strip and heat exchanger tube link into an integrated entity by swelling.
Conducting strip in the said structure is the thin plate that non-ferrous metal is rolled into, and its thickness is at 0.12～0.20mm, and the conducting strip surface is bent into the wavy rigidity that had both increased thin-plate element, effectively increases heat exchange area again, helps improving heat exchanger effectiveness.Conducting strip is the lotus root sheet, and regularly arranged axial hole cooperates with heat exchanger tube outer wall in the bundle pipes and realizes being connected by swelling on the plate face.The hole that conducting strip plate face the is worn heat exchanger tube arrangement of embarking on journey, up hole and the descending hole pitch-row that staggers mutually half, neighbouring three holes are isosceles triangle.A pitch of fins 2.0～3.5mm between the conducting strip.
The utility model compared with prior art has following good effect:
1, the conducting strip of axially evenly distributed and swelling on the heat exchanger tube outer wall significantly increases the heat exchange area of heat exchanger tube, has improved heat exchange efficiency.Under same size, identical working condition, heat exchanger tube quantity is lacked more than 3/5 than prior art, has both saved non-ferrous metal tubing, has reduced manufacturing cost again, and pipe layer medium consumption also falls on a year-on-year basis.
2, a pitch of fins is between 2.0～3.5mm between the conducting strip of swelling on the heat exchanger tube outer wall, and the pitch of fins in this size range has been improved the shell medium trafficability performance of viscosity≤N460.
3, the hole dislocation of up-downgoing is opened pitch-row half, and neighbouring three holes are isosceles triangle, effectively eliminate the heat exchange blind area, further improve heat exchange efficiency.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Be the embodiment of the utility model plate type heat interchanger shown in the accompanying drawing, it comprises bilateral lid 1, left flange 2, housing 3, dividing plate 4, right flange 5, bottom 6 and bundle pipes 7.Housing 3 shown in the accompanying drawing 1 is cylindrical shapes, and housing 3 two ends are respectively equipped with the be tightly connected left flange 2 of bilateral lid 1 and the right flange 5 of the bottom 6 that is tightly connected.Housing 3 left end outer walls are provided with radial inlet pipe 3.1, and the right-hand member outer wall is provided with radially outlet 3.2.The axially even fixedly connected dividing plate 4 that staggers mutually at interval, up and down of housing 3 inwalls.Present embodiment heat exchange area 6m
2, housing 3 inwalls are provided with 7 dividing plates 4, and fixedly connected 4 dividing plates 4 of interior upper wall, fixedly connected 3 dividing plates 4 of lower inner wall, dividing plate 4 cooperate 6 little cavitys that are interconnected of formation with bundle pipes 7.Described bundle pipes 7 is by being parallel to each other and the regular isometric heat exchanger tube 7.1 that is spaced is formed, and heat exchanger tube 7.1 is a copper pipe.The axially even 2.0～3.5mm at interval of heat exchanger tube 7.1 outer walls of the utility model in bundle pipes 7 string cover conducting strip 7.2, aluminium matter conducting strip 7.2 thickness 0.12～0.20mm, conducting strip 7.2 every row are provided with 4～16 holes, and every row is provided with 5～20 holes and heat exchanger tube 7.1 and is connected by swelling.Conducting strip 7.2 thickness 0.14mm in the present embodiment, between a pitch of fins be 3mm.Conducting strip 7.2 plate faces are made waveform, and the plate face is provided with the hole that cooperates with heat exchanger tube 7.1 and becomes column-row arrangement, the position, hole of the up-downgoing pitch-row that staggers mutually half, and neighbouring three holes are isosceles triangle.Isosceles triangle is arranged, and effectively eliminates the heat exchange blind area, has improved heat exchange efficiency.Leave the working media circulation that big pitch of fins helps viscosity≤N460 between the conducting strip 7.2.Bundle pipes 7 left ends cooperate with bilateral lid 1, and the heat exchanger tube 7.1 that is in bundle pipes 7 first halves communicates with the outlet 1.1 of bilateral lid 1, and the pipeline 7.1 of left end Lower Half communicates with the import 1.2 of bilateral lid 1.Bundle pipes 7 right-hand members and bottom 6 connect and compose the loop of heat exchanger tube 7.1.
