Inner-finned heat exchange tube, condenser and moving cold store

Abstract

The invention provides an inner-finned heat exchange tube, a condenser and a moving cold store; the inner-finned heat exchange tube comprises a center rod arranged along the axis of the heat exchange tube, and a plurality of radial rods extended radially along the center rod; each radial rod is provided with a plurality of triangular fins extended out from the radial rod. A novel inner-finned structural condensing tube is designed herein; the triangular fins on the novel structural condensing tube provide increased heat exchange area and improved fluid disturbance and improved heat exchange effect.

Description

technical field [0001] The invention relates to the field of heat exchange, in particular to an inner-fin heat exchange tube, a condenser and an assembling mobile cold storage thereof. Background technique [0002] The development of my country's cold chain logistics is still in its infancy, and there is a huge gap with developed countries. A large number of fresh products are wasted every year because they are not transported by cold chain. At present, my country is vigorously promoting the development of cold chain logistics. Cold storage is a very important part of cold chain transportation. Its construction scale and technological development directly affect the development of the entire cold chain logistics. At present, my country mainly uses fixed large-scale cold storage. Its small-scale capacity and limited use have affected the development of cold chains in my country, especially in the transportation of the first and last kilometers of the cold chain. Traditional c...

AI Technical Summary

Problems solved by technology

At present, my country mainly uses fixed large-scale cold storage. Its small-scale capacity and limited use have affected the development of cold chains in my country, especially in the transportation of the first and last kilometers of the cold chain. Traditional cold storage is the solution No, although there are some small mobile cold storages in use, but their thermal insulation effect is poor, the cold and heat bridge treatment technology is not good enough, the structure is unstable, etc., it is difficult to guarantee a good use effect

[0003] The condenser of the cold storage is equipped with a condensing tube, but the heat exchange capacity of the condensing tube is insufficient, resulting in poor cooling effect, so it is necessary to develop a new heat exchange tube
