Description

Non-welded heat exchanger with excellent corrosion resistance

The present invention relates to a heat exchanger, and more particularly, to a non-welded heat exchanger having excellent corrosion resistance by installing without welding between pipes, and improving heat exchange efficiency by smooth and rapid flow of fluid in the pipe.

A general heat exchanger heat-exchanges a heating medium and a refrigerant to recover a heat source of a heating medium thrown to the outside or a heating medium introduced from the outside. The heat source is recovered by exchanging heat with the refrigerant through the wastewater (high-temperature wastewater).

However, in the case of a heat exchanger for cooling seawater containing salt or the like, there is a problem in that the pipe is rapidly corroded by salt or the like.

In other words, there is a disadvantage in that it requires workers to put the ice loaded from the land when transporting the catches worked on the fishing boats in the sea to the fishing docks of the carriers and transporting them to the land, and also delays the operation time.

Also, since the salt concentration is lowered by adding ice, salt must also be added, and when the salt concentration of seawater and salt concentration are different, the freshness is affected.

To solve this problem, it is necessary to install a seawater cooling system for fishing rods in the carrier itself to directly cool the seawater stored in the fishing rods to maintain the freshness of the catches, and to develop a seawater cooling system that can solve all the problems that occur during transportation to land. And the need for a heat exchanger, which is the most essential part of the cooling system, is emerging.

Specifically, there is a task to create an optimal environment for fish and shellfish by preventing metal ions that affect the survival of fish and shellfish from eluting into the seawater as it has semi-permanent corrosion resistance to seawater, and the inner shaft of the pipe through which seawater flows is corrosive to seawater Corrosiveness due to welding exists when a material without problems and a pipe that is in contact with the refrigerant and the pipe are combined, and the need to solve this problem is increasing.
