Description
Technical field
What the present invention relates to is a kind of non-seal stainless steel plate-fin heat exchanger, is applicable to fields such as petrochemical industry, dynamic power machine.
Background technology
Plate-fin heat exchanger is common a kind of compact heat exchanger, and it mainly is made up of core body, end socket, adapter and bearing.The core body that carries out heat exchange be made up of a series of construction units of the position of most critical wherein, each construction unit all are made up of upper spacer, lower clapboard, the strip of paper used for sealing that is clipped in the thermofin between the dividing plate and is enclosed in the thermofin both sides.The thickness of strip of paper used for sealing is according to the height decision of fin, and generally between 6mm～12mm, the proportion of strip of paper used for sealing in heat exchanger is bigger.High temperature resistant in order to satisfy, high pressure resistant, anticorrosive this class specific (special) requirements; in fields such as petrochemical industry, refrigeration, medicine, atomic energy, Aero-Space, use fine-type stainless steel plate heat exchanger through regular meeting; because stainless density is big and cost an arm and a leg; in order to meet the demands; the fine-type stainless steel plate heat exchanger volume that generally designs is big, and cost height and space are arranged also very difficult.
Summary of the invention
The present invention is exactly at the problems referred to above, structure to traditional heat exchangers is improved, proposed a kind of non-seal stainless steel plate-fin heat exchanger, this non-seal stainless steel plate-fin heat exchanger is a kind of heat exchanger of high-efficiency compact, good seal performance, has the heat exchange efficiency height, high temperature resistant, advantage such as high pressure resistant is compared with traditional fine-type stainless steel plate heat exchanger, simple in structure, cost significantly descends.
Non-seal stainless steel plate-fin heat exchanger is to adopt following scheme to realize: non-seal stainless steel plate-fin heat exchanger comprises cover plate, dividing plate, fin, stifled circle and takes over, dividing plate four limits are provided with the flanging of certain angle, the hole, angle is arranged on the fin, place, hole, angle on fin seals with stifled circle, several dividing plates interconnect be sealed and fin constituted heat exchange core body, the cover plate for sealing of both sides up and down of heat exchange core body is taken over setting on the cover board.Core body when assembling cold fluid pass and zone of heat liberation are stacked at interval, and whole heat exchanger comprises that adapter all connects with soldering and seals.
Good sealing effect of the present invention, integral body all adopt soldering to connect, and phenomenon can not take place to scurry mutually cold fluid and hot fluid, and good seal performance can not revealed, and is high temperature resistant, high pressure resistant.Compare with traditional fine-type stainless steel plate heat exchanger, the present invention only is made up of cover plate, dividing plate, fin, stifled circle and adapter, and structure is simpler, and cost significantly descends, and is fit to produce in batches, has better economic and social benefit.
