Problems solved by technology

[0003] However, the traditional arcuate baffle heat exchanger also has some shortcomings, such as large flow resistance, a large number of flow dead zones, and low heat transfer efficiency.
Therefore, under the new situation of energy conservation and emission reduction, its development has been greatly restricted.

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiment is only an illustration of the gist of the present invention, rather than limiting the protection scope of the present invention.

[0022] Such as figure 1 As shown, a baffle plate 11 provided by the present invention includes a body 1 provided with a tube hole 2, which is installed in a cylindrical shell of a heat exchanger, wherein one side of the edge surface of the body is a mounting surface, so The mounting surface is attached to the inner wall of the housing, and the other side of the edge surface of the body is a circulation notch surface 3, and the circulation notch surface and the inner wall 5 of the housing form a circulation notch 4 for the medium to pass through. The body is made of foam metal material.

[0023] The baffle of the present invention is made of foam metal material. Compared with ...

Abstract

The invention provides a baffle plate and a shell-and-tube heat exchanger. The baffle plate comprises a body provided with a pipe hole and is installed in a cylindrical shell of the heat exchanger. One side of the edge face of the body is an installing face. The installing face is attached to the inner wall of the shell. The other side of the edge face of the body is a circulation notch face. Thecirculation notch face and the inner wall of the shell form a circulation notch in a surrounding mode, and a medium passes through the circulation notch. The body is made of foam metal material. The turbulence degree of flowing can be improved effectively, the influence caused by a common baffle plate on flowing form change is lowered, then the flowing dead zone of a traditional shell-and-tube heat exchanger is avoided effectively, and the effects that heat exchange efficiency of the heat exchanger is promoted effectively and pressure drop is lowered are achieved.

Description

technical field [0001] The invention relates to the technical field of thermal energy, in particular to a baffle plate and a shell-and-tube heat exchanger. Background technique [0002] Shell-and-tube heat exchangers, also known as shell-and-tube heat exchangers, have the advantages of simple structure, mature design and manufacturing process, and high safety, so they are widely used in petrochemical and other fields. In shell-and-tube heat exchangers, traditional bow-shaped baffle heat exchangers account for 70% to 80% of the total. [0003] However, the traditional bow-shaped baffle heat exchanger also has some shortcomings, such as large flow resistance, a large number of flow dead zones, and low heat transfer efficiency. Therefore, under the new situation of energy saving and emission reduction, its development has been greatly restricted. Therefore, in response to these shortcomings, a baffle and shell-and-tube heat exchanger with simple structure and mature technolog...
