Abstract

A plate heat exchanger plate bundle is characterized in that: each plate sheet is provided with a pressed concave platform at a distance; two plate sheets are welded to form one set at both ends and the concave platform during assembly; and the plate sheet sets are piled up and then are welded with the end plates at both ends of a plate bundle and a filled insert block to form the plate bundle, thereby completing the two-phase separation of the plate bundle. The heat exchanger plate bundle adopting the structure separates each plate sheet set into a plurality of independent plate pass spaces through increasing the vertical welding seam inside the plate sheet, thereby increasing the strength of the plate bundle, completing the treatment of local leakage of the plate bundle through local plugging and ensuring convenient cleaning of the plate bundle.

Description

A kind of plate type heat exchanger plate bundle

Technical field

The utility model relates to the heat-exchange apparatus field, particularly a kind of manufacture method of full welded plate formula heat exchanger plate bundle.

Background technology

Plate type heat exchanger is a kind of efficient and compact heat transmission equipment.Have plurality of advantages such as heat transfer coefficient height, the pressure loss are little, compact conformation, and along with the improvement of structure and the raising of maximization manufacturing technology, the application of plate type heat exchanger is subject to people's attention day by day.Along with the research of full welded plate formula heat exchanger is used, improved the serviceability temperature and the pressure of plate type heat exchanger, enlarge its scope of application.These welded plate type heat exchangers have been used for the processes such as heating, cooling, condensation, evaporation and recuperation of heat in fields such as chemical industry, oil, power, metallurgy more and more.

At present, the subject matter that exists during full welded plate formula heat exchanger uses is that plate bundle bearing capacity is low, plate Shu Qingjie difficulty, the processing complexity after leaking appears in the plate bundle.

Summary of the invention

The utility model provides a kind of plate type heat exchanger plate bundle, pressing certain distance on every plate increases the concave station of compacting, during assembling by two plates at two ends and the concave station place form one group by welding is fixing, with after the plate groups stack combinations and the end plate at plate bundle two ends, fill the welding of inserting and form the plate bundle, finish two journeys of plate bundle and separate.The shape of end plate can be that rectangle also can be circular.

The heat exchanger plate bundle of this structure, by the vertical portion weld seam that increases plate groups inside each plate groups is divided into a plurality of independently plate journeys space, first has increased the intensity of plate bundle, and second can handle by local shutoff when the local appearance of plate bundle is leaked, and the third party is the cleaning of plate bundle just.

The specific embodiment

The utility model heat exchanger plate bundle is made and is achieved in that

When the compacting plate, cut apart concave station in the flat limit, vertical compacting both sides and the centre of plate as required, plate, the central longitudinal weld seam of plate groups is welded with the technology of Contact welding or pressure welding in the combination of the plate up and down back that cooperates, then with technology mode welding plate groups both sides weld seam with Laser Welding, TIG or MIG weldering.

Plate groups quantity as required is with the plate groups of the making composing plate bundle body (1) that superposes up and down, then with the attachment weld with the technology mode welding plate groups of Laser Welding, TIG or MIG weldering.

Determine the quantity of plate bundle stiffener (2) according to the length of plate bundle, installing plate bundle stiffener is then with the welding of finishing plate bundle group and plate bundle stiffener with the technology mode of Laser Welding, TIG or MIG weldering.

At the two ends of plate bundle body end plate (3) is installed, in plate bundle end of body hole, is installed to fill and insert (4), finish plate bundle group with the technology mode that welds with Laser Welding, TIG or MIG then and filling is inserted, the welding of end plate.Consider that welding procedure can be at the end processing featheredge that filling is inserted.

Claims

1, a kind of plate type heat exchanger plate bundle is characterized in that: the plate bundle is to insert and be welded to form in plate bundle end plate, the end at after being superposeed by the plate groups that the wavy metal plate is welded to form and two ends.

2, a kind of plate type heat exchanger plate bundle as claimed in claim 1, it is characterized in that: every corrugated cardboard sheet of plate groups all is suppressed with the convex-concave platform that matches, and forms one group of plate by welding, and the plate journey of plate groups is split into the several separate space.

3, a kind of plate type heat exchanger plate bundle as claimed in claim 1 is characterized in that: inserted by filling in plate bundle group end and the end plate welding is finished.
