Efficient heat exchanger

Abstract

The invention relates to the industrial field and discloses a large-diameter pipeline for an efficient heat exchanger. A plurality of turbulence devices are arranged inside the pipeline. The outer wall of the pipeline is provided with axial protrusions for increasing radiating area, and the protrusions can be in any shape. The pipeline is made of high thermal conductivity material, such as stainless steel and aluminum alloy. The cross section of the pipeline can be in any regular or irregular shapes, such as round, square, diamond and trapezoid, and the longitudinal section can also be in any shapes. The turbulence devices are connected with the inner wall of the pipeline and are arranged optionally. The turbulence devices are planar sheets or curved-surface sheets in any shape, and the included angle between the turbulence devices and the waterflow direction is smaller than 90 DEG. The turbulence devices occupy less than two thirds of the diametric section. The pipeline high in thermal conductivity and specific surface area quickly exchanges heat with outside to allow heat carrier in the pipeline to fully contact with the inner surface of the pipeline, so that higher heat exchange efficiency is achieved. The efficient heat exchanger is simple in structure, low in pipeline pressure loss and attractive in appearance.

Description

technical field [0001] The invention relates to the industrial field, in particular to a high-efficiency heat exchanger for public places and households. Background technique [0002] Traditional radiators use a continuous hollow tubular flow path, in which heat carriers such as water, steam, antifreeze, etc. are used in the middle to increase or decrease the surface temperature of the radiator and exchange heat with the external space, so as to achieve a complete cooling of the space. Heating and cooling purposes. [0003] Although this heat dissipation technology has simple structure, low cost and flexible use scale, it is mostly used in central heating projects, but the heating process is long and the internal pressure is high. For a separate process space, it is necessary to increase the number of pipelines to improve heat exchange efficiency, such as geothermal heating, and other capillary heat exchangers hidden in the wall. [0004] The problem with this technology i...

Problems solved by technology

[0004] The problem with this technology is that if the heat pipe is used, the diameter of the pipe is thinner and the pressure loss is larger; if the diameter of the pipe is thicker, the inner surface of the pipe only exchanges heat with the carrier in the inner contact part of the pipe, while the center of the pipe Part of the carrier has left the heat dissipation pipeline before the heat exchange occurs, the heat carrier is not fully utilized, and the heat transfer efficiency is low
