Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, from the figure as can be seen, plate type heat exchanger of the present utility model mainly by heat exchanger body 1, two pressure strips, take over 2 and flange 3 form.Heat exchanger body 1 has the metal sheet of wave groove to arrange at regular intervals by many punching presses, passes through gasket seal around the adjacent plate.The hole, four angles of plate and pad setting has formed the distributing pipe and the manifold trunk of liquid, and justice is reasonably separated cold fluid and hot fluid simultaneously, and it is flowed in the runner of every plate both sides respectively, carries out heat exchange by plate.Pressure strip is positioned at heat exchanger body 1 two ends, wherein one is fixed pressure plate 4, do not contact with fluid, another piece is a movable pressure plate 5, position in fixed pressure plate 4 and 5 liang of vertical edge correspondences of movable pressure plate has the hole, fishbolt 6 passes top perforate fixedlys connected fixed pressure plate 4 with movable pressure plate 5, simultaneously heat exchanger body 1 is clamped between fixed pressure plate 4 and the movable pressure plate 5 tightly.The user can unload movable pressure plate 5 as required, thus the quantity of increase and decrease plate.By regulating the nut on the fishbolt 6, can adjust the tightness of pad between metal sheet.But nut can not be twisted De Taisong, and synthetic or leakage takes place when fluid flows between plate so easily, can not twist too tightly, otherwise gasket seal is easily aging.On fixed pressure plate 4, be provided with cooling liquid inlet and take over and need the liquid outlet adapter of heat exchange, on movable pressure plate 5, be provided with the liquid-inlet adapter that heat exchange was taken over and needed to cooling liquid outlet.Cooling liquid inlet take over and discharge connection between and need the liquid-inlet of heat exchange take over and discharge connection between be communicated with by separately runner in the heat exchanger body.Take over termination at each root and be provided with flange 3, be used for outside cooling fluid or need the fluid pipeline of heat exchange to connect.
