 We have tried our best to make plate type heat exchanger bread n butter for you, after going through this article u will not only understand the topic about also u can explain it to others too (Don't forget to mention us;) Plate type exchanger consists of variable number of  thin corrugated plates joined parallel together, creating a cavity for fluid flow inside it. Alternate sides of the plate carry two different fluids, between which heat transfer is carried out. These are gasketed Titanium plates,clamped together between a closing pressure plate and a frame plate,these plates are clamped together with the help of clamping bolts.The inlet and outlet branches for each liquid is attached to the frame plate. The arrangement of gasket between the plates provides passage between adjacent plates for the cooling liquid and hot liquid.Neoprene rubber gasket is stack with adhesive to the plate in addition to this a tell tale hole arrangement is also provided at each branch point to ...

Heat exchangers are the machinery in which heat transfer takes place, one of its type used on ship is shell and tube type. Heat transfer takes place in mix flow pattern in this heat exchanger (cross flow, counter flow and parallel flow).The coolant flows through the tubes while the fluid to be cooled surrounds the tubes (Intercooler of compressors is exception). Shell is made up of cast iron with end covers on either side and bundle of tubes is held inside the shell.The tubes are made up of aluminum brass and these tubes are sealed into the naval brass tube plates at both ends,one plate is fixed while other is free to allow for expansion & contration of the tubes.The tube bundle has baffles fitted which supports the stack and also serves to direct the liquid to be cooled up and down over the tubes for better cooling. The fixed end plate is sandwiched between the shell and the end cover with gaskets on either side.The movable plate is provided with synthetic rubber 'o' rings...
