Abstract

The utility model discloses a plate-shell type heat exchanger comprising a housing, tube plates, a plate bundle, support plates, seal liner plates and seal bars. A tube bundle of the heat exchanger adopts the plate bundle formed by welding of mutually-overlapping plate sheets with convex and concave ridges in a convex ridge-to-convex ridge and concave ridge-to-concave ridge manner. Straight edges are arranged around every plate sheet in order to be convenient for welding. Based on length of the plate bundle, a plurality of support plates and seal liner plates are used to support and fix the plate bundle, connection positions of the straight edges and the seal liner plates are sealed by the seal bars, and two ends of the plate bundle are welded with the seal liner plates and then are welded with the tube plates. Tube and casing pass mediums respective move in respective channels, flow states change all the time, heat exchange is sufficient and a heat transfer effect is raised.

Description

A kind of lamella heat exchanger

One, technical field

The utility model belongs to heat exchanger manufacturing technology field, is specifically related to a kind of heat exchanger as petrochemical equipment.

Two, background technology

Heat exchanger is used very extensive at petroleum chemical industry, common concern be how energy-conservation and improve heat exchange efficiency, the shell-and-tube heat exchanger form has experienced segmental baffle formula heat exchanger, the deflection bar type heat exchanger, helical baffles formula heat exchanger, helically twisted heat exchange of heat pipe, supporting construction has experienced from supporting to unbraced structure, heat exchanger tube has experienced common light pipe, elliptical tube, bellows, various enhanced tubes such as helically twisted pipe, main problem all is to improve the heat-transfer effect of heat exchanger, improve heat transfer coefficient, these versions respectively have advantage, but still await further raising.

Three, summary of the invention

The utility model provides a kind of lamella heat exchanger, based on the conventional tube shell heat exchanger, housing is the housing of conventional tube shell heat exchanger, and tube bank is to have the plate bundle that the plate of concavo-convex ripple overlaps each other and forms dimpled grain burr, dimpled grain with burr, pipe, shell side medium are respectively in the motion of separately passage, flow regime changes constantly, improves heat-transfer effect.

A kind of lamella heat exchanger comprises: housing, tube sheet, plate bundle, support plate, sealed liner and sealing strip.The technical scheme that its technical problem that solves the utility model adopts is: what a kind of tube bank of lamella heat exchanger was adopted is the plate bundle, the plate bundle is burr, dimpled grain to be overlapped each other to dimpled grain with burr by the plate that has concavo-convex ripple to be welded to form, all straight flange is arranged around the every plate so that weld, the concavo-convex ripple of plate has different shapes; According to the length of plate bundle, adopt a plurality of support plates, sealed liner with support fixation plate bundle, straight flange and sealed liner junction seal with sealing strip, and plate bundle two ends and sealed liner welding are welded with tube sheet again.
