Design of the Lubricating Oil Cooler

ABSTRACT

Heat exchanger is one of the most common heat exchange equipment in industrial; it is one of the equipments used for heat transfer from high temperature flow to the low one. This kind of equipment can make fluid reach specified temperature in order to meet the process requirements. Tube and shell heat exchanger is the most widely used and indispensable equipment in chemical energy field because it has a simple structure, high in thermal efficiency, easy to clean, etc.

The design of the lubricating oil cooler is the use of shell and tube heat exchanger structure. The design mainly includes the working principle , classification and some problems often encountered in the design process of shell and tube heat exchanger, The second part is the thermodynamic calculation，content of structure calculation and thermal compensation, etc. Heat exchanger design manual is referring to national standard or other authority, to ensure the rationality of the design and accuracy. And drawing equipment drawings equivalent to 1 drawings total 6 rose.

Keywords: Lubricating oil cooler; Tube and shell heat exchanger; Design
