Heat exchanger

Abstract

The invention discloses a heat exchanger. The heat exchanger comprises a circulating pipeline for allowing low-temperature fluid to pass through and a mesh-shaped pipeline which is arranged in the circulating pipeline for allowing high-temperature fluid to pass through; the mesh-shaped pipeline comprises a first heat exchange mesh pipe and a second heat exchange mesh tube which are arranged in parallel and communicate with each other; first mesh holes for allowing the low-temperature fluid to pass through in the first heat exchange mesh tube and second mesh holes for allowing the low-temperature fluid to pass through in the second heat exchange mesh tube are alternatively formed; and the mesh-shaped pipeline comprises an inlet for allowing low-temperature fluid to flow into the first heatexchange mesh tube and the second heat exchange mesh tube, and an outlet for enabling heat-exchanged low-temperature fluid to flow out from the first heat exchange mesh tube and the second heat exchange mesh tube. The heat exchanger disclosed by the invention can provide resistance for low-temperature fluid which flows through from the circulating pipeline, has effects of reducing flow speed and disturbing flow for low-temperature fluid, increases a contact heat-exchange area between low-temperature fluid and high-temperature fluid; and moreover, flow of high-temperature fluid is increased, sothat heat exchange efficiency of the heat exchanger is finally improved.

Description

technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a heat exchanger. Background technique [0002] A heat exchanger is a kind of heat transfer between two or more types of fluids at different temperatures, so that the heat is transferred from the high-temperature fluid to the low-temperature fluid, so that the low-temperature fluid reaches the required target temperature or cools the high-temperature fluid, and finally reaches the process. need. Heat exchanger is a kind of equipment that develops and utilizes secondary energy, realizes waste heat recovery, saves energy and improves energy utilization rate. It has a large market demand and is widely used in ships, petroleum, chemical industry, refrigeration machinery and other fields. [0003] The existing seawater desalination system is generally equipped with a multi-effect distillation device, the last effect of the multi-effect distillation device will generate ...
