Embodiment Construction

[0021] Traditional tubular heat exchangers are generally composed of heat exchange tubes, enhanced heat exchange elements and auxiliary heat exchange devices. Enhanced heat exchange elements can be arranged inside and / or outside the heat exchange tubes, such as aluminum foil, fins, etc. , the role of the turbulence core arranged in the heat exchange tube is to enhance the heat exchange, and the auxiliary heat exchange device is used to accelerate the flow of the fluid medium, and the function is also to enhance the heat exchange effect, such as the commonly used auxiliary heat exchange devices such as fans and water pumps .

[0022] figure 1 One embodiment of the invention is shown. The heat exchanger consists of a heat exchange tube 1 and a metal foam 3 covering the surface of the heat exchange tube 1. The metal foam 3 is burnt on the outer surface of the heat exchange tube 1. Of course, the metal foam 3 can also be bonded. , welding and other methods to connect with the he...

Abstract

A heat exchanger of tubular type consists of heat exchange tube, heat exchange component set on external surface of said tube and auxiliary heat exchange unit for assisting heat exchange. It is featured as using metal foam as heat exchange component covered on external of said tube and forming metal foam holes at internal of metal foam to let gas or liquid pass through.

Description

technical field [0001] The invention relates to a heat exchanger for industrial equipment, especially a tube heat exchanger. Background technique [0002] Heat exchanger is a kind of heat exchange equipment commonly used in industry. It is widely used in air conditioners, ships, automobiles and other fields to transfer heat from high temperature fluid medium to low temperature fluid medium. For example, the seawater / freshwater heat exchanger commonly used on ships, the entire cooling system is composed of an open seawater system and a closed freshwater system. Lower temperature seawater and higher temperature freshwater flow through the heat exchanger at the same time, and the seawater converts the freshwater Part of the heat is taken away, and the cooled fresh water is sent back to the engine to cool the engine. [0003] According to the structural form, heat exchangers are generally divided into tubular heat exchangers and plate heat exchangers. D...
