High-efficiency low-resistance lubricating oil cooler

Abstract

The invention discloses a high-efficiency low-resistance lubricating oil cooler. The high-efficiency low-resistance lubricating oil cooler comprises a shell and a cooling core body; a left tube plateand a left tube box connected with the left tube plate are arranged at the left end of the shell, and a right tube plate and a right tube box connected with the right tube plate are arranged at the right end of the shell; a tube pass cooling water inlet and a tube pass cooling water outlet are formed in the left tube box; a shell-pass lubricating oil inlet is tangentially formed in the upper sideface of the shell, and a shell-pass lubricating oil outlet is tangentially formed in the lower side face of the shell; the cooling core body comprises a diversion fastening cylinder and a plurality ofheat exchange tubes arranged in parallel, the two ends of each heat exchange tube are correspondingly connected with the left tube plate and the right tube plate, and the diversion fastening tube iswrapped outside the heat exchange tube; the diversion fastening cylinder is welded with an annular support baffle which is welded and fixedly arranged on the left tube plate through a pull rod; and the shell is provided with a drain port and an exhaust port. The high-efficiency low-resistance lubricating oil cooler has the advantages of being high in heat exchange efficiency, small in flowing resistance, compact in size, light in weight, low in cost, safe, reliable and the like; and the high-efficiency low-resistance lubricating oil cooler is very suitable for efficient heat exchange in limited space of moving tools such as ships, airplanes and automobiles.

Description

technical field [0001] The invention relates to the technical field of heat exchanger manufacture, in particular to a lubricating oil cooler with high efficiency and low resistance. Background technique [0002] The lubricating oil cooler is an important part of the marine diesel engine cooling system, and there are two types of shell-and-tube type and plate type commonly used at present. The plate heat exchanger has the advantages of high efficiency and compact structure. However, since seawater is commonly used as the cooling medium for ship heat exchange equipment, it is highly corrosive. Therefore, when a plate oil cooler is used, the plate must be made of titanium alloy. As a result, the manufacturing cost of the equipment is high, and the sealing periphery of the plate heat exchanger is too long, the chance of leakage is large, there are hidden dangers, and it is difficult to ensure the safe navigation of the ship at sea. The shell-and-tube lubricating oil cooler has ...

AI Technical Summary

Problems solved by technology

At present, the cooling system of marine diesel engines tends to be more efficient, compact and lightweight, which puts forward higher restrictions on installation space and overall weight. However, the traditional baffle-tube shell-and-tube lubricating oil cooler has low heat transfer efficiency. , large flow resistance, many consumables, large volume and other defects limit the rapid development of marine diesel engine cooling systems
