Problems solved by technology

Due to the presence of fins and the large size and heavy weight of the metal tubes used, the size and weight of the heat exchanger are too large and heavy
As a result, more space needs to be arranged in the entire steam generation system to place the heat exchanger, resulting in a decrease in the hot water storage capacity of the heat exchanger
On the other hand, the weight of the heat exchanger also has a great impact on the overall installation and transportation.

Abstract

The invention discloses a built-in type combined heat tube. The built-in type combined heat tube comprises a U-shaped shell, a support and multiple minisize micro-channel metal heat dissipation roundtubes, wherein the support is fixedly connected to the opened position of the U-shaped shell. Each minisize micro-channel metal heat dissipation round tube comprises a condensation section, a heat insulation section and an evaporation section. The support is used for fixedly supporting the condensation sections of the multiple minisize micro-channel metal heat dissipation round tubes. The inner diameter of each minisize micro-channel metal heat dissipation round tube ranges from 0.05 mm to 0.6 mm; the wall thickness of each minisize micro-channel metal heat dissipation round tube ranges from 0.15 mm to 0.25 mm; and the outer diameter of each minisize micro-channel metal heat dissipation round tube is below 0.9 mm. A closed space is formed between the U-shaped shell and the support (2). Theheat insulation sections and the evaporation sections of the minisize micro-channel metal heat dissipation round tubes are arranged in the closed space. The tail ends of the evaporation sections areclose to the bottom of the U-shaped shell.

Description

technical field [0001] The invention designs a micro-microchannel heat exchange technology, in particular a built-in combined heat pipe. Background technique [0002] Low-temperature waste heat is waste heat below 350°C, and the quantity is extremely large, including hot water, low-grade flue gas and steam generated in the production process of metallurgy, building materials, petrochemical and other industries. At present, low-temperature waste heat is mainly used in heating, hot water and other fields. At present, domestic and civil low-temperature waste heat steam generation systems are rare, and there are only some extruded aluminum alloy metal tubes or flat tubes with fins, and the inner hole size of the tubes is greater than 0.6mm. And compared with the traditional tube-fin type, tube-belt type, parallel flow type, plate-fin type, stacked type and other heat exchangers, the heat exchange efficiency is not particularly significantly improved. Due to the presence of fin...
