Marine condenser with carbon steel and polyethylene hot-melted combined pipe box

Abstract

The invention relates to the field of refrigeration and especially relates to a marine condenser with a carbon steel and polyethylene hot-melted combined pipe box. The marine condenser is mainly used for solving the technical problems of the prior art that a zinc block is corroded when the zinc block is adopted by the condenser for protecting a pipe box, the pipe box is detached and overhauled, a gasket is manufactured again, the operation is troublesome, the position and the construction of the zinc block are specially designed, the parts of the pipe box are increased, the structure of the equipment is more complex, and the like. The marine condenser comprises a cylinder, wherein a front pipe plate and a rear pipe plate are respectively arranged at front and rear two ends of the cylinder; a front pipe box and a rear pipe box are respectively connected with the front and rear pipe plates; a water inlet and a water outlet are arranged on the front pipe box; a plurality of heat exchange pipes are arranged in the cylinder; a refrigerant inlet and a refrigerant outlet are connected with the exterior of the cylinder; plastic lining layers are arranged inside the front pipe box and the rear pipe box; and the plastic lining layers are plastic and steel substrate hot-melted combined layers.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to a marine condenser with a carbon steel and polyethylene hot-melt joint tube box. Background technique [0002] Ocean-going fishing vessels have been operating on the ocean for more than half a year. If there is a problem with the refrigeration system during the operation, the economic loss will be huge. Therefore, it is very important to ensure the reliability of the refrigeration system. The Chinese patent discloses a marine Freon condenser (authorized announcement number: CN 101576335A), which includes a cylinder, the two ends of the cylinder are respectively welded with tube sheets, the outer ends of the tube sheets are connected with heads, and the inside of the cylinder is installed There are heat exchange tubes, and the two ends of the heat exchange tubes are respectively expanded and connected to the tube plates at both ends of the cylinder. A gas baffle is installed in the c...

Problems solved by technology

[0003] The present invention provides a marine condenser with a carbon steel and polyethylene hot-melt joint pipe box, which mainly solves the problem in the prior art that the zinc block will be corroded when the condenser uses zinc blocks to preserve the pipe box, and the pipe box needs to be corroded. Disassemble and overhaul, the gasket needs to be remade, the operation is troublesome, the position and structure of the zinc block need special design, and at the same time, the parts of the pipe box are added, which makes the equipment structure more complicated and other technical problems
