It the utility model is related to heat exchanger field, disclose a kind of diagonal stream welded plate type heat exchanger, the plate heat exchanger is included by the compressing heat exchange plate core of hexagon plate, end socket, and two parallel short sides are open in the hexagon plate, remaining four edges is using the sealing of metal insert;Adjacent hexagon plate positive and negative alternate arrangement, the heat exchange plate core upper and lower ends are respectively equipped with two bearing plates.The problem of the utility model solves welded plate heat exchanger and is chronically at thermal stress fatigue work, and heat exchanger service life is short.The utility model plate ripple struction is simple, easily molded;Plate groups conjunction contact rate is high, enhances turbulence effects;Cold and hot inlet and outlet nozzle flexible arrangement;Media of both sides can completely countercurrently.

Description

A kind of diagonal stream welded plate type heat exchanger
Technical field
The utility model is specifically related to heat exchanger field, relates more specifically to a kind of diagonal stream welded plate type heat exchanger.
Background technology
Traditional dismountable plate type heat exchanger is by rubber seal, by certain way group by compressing corrugated sheet After conjunction with pressure strip compress form, plate is equipped with four corner apertures, make its cold and hot medium flowed in the runner of plate both sides into Row heat exchange, its advantage is compact-sized, heat exchange efficiency is high, but due to the use of sealing rubber pad, causes traditional dismountable plate type to change Hot device cannot bear high-temperature and high-pressure conditions and corrode in more serious operating mode.
Welded plate heat exchanger overcomes the above problem, has the advantages that high temperature resistant, high pressure compared with removable, due to The advantages of combining Conventional plate-type and pipe heat exchanger so that welded plate heat exchanger can be widely applied for oil, chemical industry, The industries such as electric power, metallurgy and new energy.But the welded plate heat exchanger of existing processing and manufacturing technology, due to being transported in worst hot case There is larger thermal stress deformation to produce in row, being chronically at thermal stress fatigue work reduces the service life of equipment.
Utility model content
Thermal stress fatigue work is chronically to solve welded plate heat exchanger, the problem of heat exchanger service life is short, The utility model provides a kind of diagonal stream welded plate type heat exchanger.
The utility model adopts the following technical solution:A kind of diagonal stream welded plate type heat exchanger, the plate heat exchanger include By the compressing heat exchange plate core of hexagon plate, end socket, two parallel short sides are open in the hexagon plate, remaining Four edges are sealed using metal insert;Adjacent hexagon plate positive and negative alternate arrangement, the heat exchange plate core upper and lower ends difference Equipped with two bearing plates.
Material collecting region is formed between the heat exchange plate core and end socket.
Connected between the heat exchange plate core and end socket by the connecting plate with expansion joint.
Welded in the utility model between plate and end socket by the connecting plate with expansion joint, make heat exchange plate core and housing Between thermal stress deformation reduce, improve the thermal distortion compensation ability of heat exchanger, be effectively applied to big specific of difference variation Operating mode.The utility model plate ripple struction is simple, easily molded;Plate groups conjunction contact rate is high, enhances turbulence effects;It is cold and hot into Outlet spout flexible arrangement;Media of both sides can completely countercurrently.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Referring to attached drawing 1-3, the utility model oblique ripple full-welding plate-type heat exchanger, including two pieces of clamping plates, 2, four envelopes First 6 and the housing of 8 welding fabrication of bearing plate, heat exchange plate core 9 is equipped with the housing, and heat exchange plate core 9 is by multiple oblique ripples six Side shape plate 7 forms, and two parallel short sides are open in the hexagon plate, remaining four edges is close using metal insert 10 Envelope;Adjacent 7 positive and negative alternate of hexagon plate arrangement.Adjacent plate is set to form right-angled intersection circulation road.The opening 14 and envelope First 6 cavity connection, and import 101 hot with end socket 6, heat outlet 102 communicate respectively, import 201 cold with end socket, cold outlet 202 connect It is logical;Cold and hot side medium flows in plate both sides and can realize complete adverse current respectively.End socket 6 described in the utility model, clamping plate 2nd, bearing plate 8 forms closed hexahedron housing all using welded seal form.Wherein front and rear clamping plate first bolts cooperation, uses Bolt, which is exchanged heat after plate core clamps, can improve its bearing capacity, it is ensured that the normal operation in each high-low pressure operating mode.
In order to improve heat transfer efficiency and bearing capacity in the utility model, upper and lower ends are equipped with two described in the plate core 9 that exchanges heat Bearing plate 8, bearing plate 8 are similarly welded seal with metal sealing insert 10.
The inlet and outlet pipe connecting flange of different directions can be equipped with the utility model at end socket, can in operating mode is actually used The flexible arrangement nozzle position in the environment of limited space.
It is described heat exchange plate core 9 be connected with end socket 6 by using the connecting plate 12 with expansion joint 15 so that heat exchange plate core and There is preferable thermal stress compensation performance between housing.
Form material collecting region 13 between the heat exchange plate core 9 and end socket 6, material collection area 13 can as medium buffering simultaneously Fluid is set to be evenly distributed to each passage.
The combination of the utility model plate ripple is simple, easily molded;Plate contact rate is high, strengthens turbulence effects, improves biography The thermal efficiency;Heat exchange plate core uses the connecting plate with expansion joint to be connected with housing, has certain stretch between plate core and end socket Space, has good thermal stress compensation performance, substantially increases service life of the plate heat exchanger in hot environment;It is cold and hot Inlet and outlet nozzle is disposed with larger flexibility, and the arrangement of different azimuth can be achieved in the application of limited space;And cold and hot both sides Medium can realize complete adverse current.The utility model structure is novel, due to that can bear high temperature and high pressure condition, has expanded board-like heat exchange Device application range, and may replace traditional shell-and-tube heat exchanger of part.
