Abstract
The utility model provides a helical plate heat exchanger specially used for the low voltage industry, wherein the inner helical ends of two helical heat exchange plates that are arranged at the interval are connected with each other by a central clapboard; the central clapboard is used for dividing the clearance between the two helical heat exchange plates into two helical coolant and heating medium channels; the upper ends and the lower ends of the coolant and heating medium channels are closed by plugs; the inner helical ends and the outer helical ends of the coolant and heating medium channels are respectively connected with a cold medium and heating medium inlet/outlet; the two sides of the central clapboard are respectively provided with a semi-circle end plate; the end surfaces of the semi-circle end plates are welded with the central clapboard; the other ends of the semi-circle end plates are welded with cushion plates; and the outlines of the cushion plates are consistent with the outlines of the helical heat exchange plates. The helical plate heat exchanger has the main benefits of effectively protecting the central clapboard of the helical heat exchange plates and effectively controlling the problem due to the nonuniform stress of base metal as the central aperture of the helical heat exchange plate is oversized after the whole plates are coiled, so as to prolong the service lives of the helical heat exchange plates.
Description
Technical field
The utility model relates to a kind of spiral-plate heat exchanger, belongs to technical field of heat exchange device.
Background technology
The application of heat exchanger in industrial production is very general, for example all occupies very consequence at each industrial departments such as petrochemical industry, light industry, medicine, food processing, medicine and Aero-Space.
In the existing spiral-plate heat exchanger, the inside spin end of the helical form heat exchanger plates that two is intervally arranged joins by a central partition plate, central partition plate is divided into two spiral helicine refrigerants, heating agent passage with the gap between the two helical form heat exchanger plates, the upper and lower side of this refrigerant, heating agent passage is by shutoff, and the inside and outside spiral end of refrigerant, heating agent passage connects the import and export of hot and cold medium respectively.
The special-purpose spiral-plate heat exchanger of low pressure industry commonly used generally can produce the problem that makes the mother metal unbalance stress owing to center bore is bigger than normal after whole coiled sheet system.If but directly on mother metal, welding, crackle may appear in the heat affected area of generation, influences the use of heat exchanger.
The utility model content
The purpose of this utility model is to solve above-mentioned technical problem, provides long low pressure industry in a kind of service life special-purpose spiral-plate heat exchanger.
The purpose of this utility model is achieved through the following technical solutions:
The special-purpose spiral-plate heat exchanger of a kind of low pressure industry, the inside spin end of the helical form heat exchanger plates that two is intervally arranged joins by a central partition plate, described central partition plate is divided into two spiral helicine refrigerants with the gap between the two helical form heat exchanger plates, the heating agent passage, described refrigerant, the upper and lower side of heating agent passage is by the end socket shutoff, described refrigerant, in the heating agent passage, the external spiral end connects cold respectively, the import and export of thermal medium, the both sides of described central partition plate are respectively equipped with a semicircle end plate, the end face of described semicircle end plate is welded in described central partition plate, the other end of described semicircle end plate is welded with backing plate, and the outline of described backing plate is consistent with the profile of described helical form heat exchanger plates.
Further, an end of described backing plate is welded in described helical form heat exchanger plates.

The specific embodiment
About addressing other technologies content, characteristics and effect before the utility model, in the following detailed description that cooperates with reference to one of graphic preferred embodiment, can clearly present.
Consult illustrated in figures 1 and 2ly, the spiral-plate heat exchanger of the utility model preferred embodiment mainly is exclusively used in the low pressure industry, is meant that its internal pressure generally is lower than 0.6MPa.
The same with prior art, the inside spin end of two helical form heat exchanger plates that are intervally arranged of this spiral-plate heat exchanger joins by a central partition plate 2, and described central partition plate 2 is divided into two spiral helicine refrigerant passages and heating agent passage with the gap between two helical form heat exchanger plates 1.
The upper and lower side of described refrigerant, heating agent passage is by the end socket shutoff, and this end socket refers generally to be located at the shell in the helical form heat exchanger plates outside.The inside and outside spiral end of described refrigerant, heating agent passage connects the import and export of hot and cold medium respectively.
Characteristics of the present utility model are, the both sides of described central partition plate 2 are respectively equipped with a semicircle end plate 4, the end face of described semicircle end plate 4 is welded in described central partition plate 2, the other end of described semicircle end plate 4 is welded with backing plate 3, and the outline of described backing plate 3 is consistent with the profile of described helical form heat exchanger plates 1.One end of described backing plate 3 is welded in described helical form heat exchanger plates 1.
Further, the thickness of described backing plate 3 equals the thickness of described helical form heat exchanger plates 1.The width of described backing plate 3 is 70～90 millimeters.
Structure of the present utility model has been protected the central partition plate of spiral-plate heat exchanger effectively, and effectively control is put in order after the coiled sheet system because the center bore mother metal unbalance stress problem that causes bigger than normal.
Although be the example purpose, preferred implementation of the present utility model is disclosed, but those of ordinary skill in the art will recognize that under situation about not breaking away from by the disclosed scope and spirit of the present utility model of appending claims, various improvement, increase and replacement are possible.
