Product Brief of 3D Heat Pipe Heat Exchanger
I. Product Overview
The 3D heat pipe heat exchanger is a high-efficiency heat exchange device independently developed by Beijing Detiandixing Technology Development Co., Ltd. It breaks through the limitations of traditional 2D heat transfer and achieves multi-directional and multi-dimensional heat transfer through 3D spatial heat transfer technology. Its core adopts gravity or capillary force to drive the circulation of working fluid, featuring both high heat exchange efficiency and flexible installation characteristics, and is suitable for scenarios such as commercial building ventilation systems and industrial waste heat recovery.
II. Core Characteristics
Two Modes for Driving Working Fluid Circulation
- Vertical installation: Realizes working fluid reflux and evaporation phase change relying on gravity, without external power.
- Horizontal/Inclined installation: The special groove structure on the inner wall generates capillary force to ensure stable circulation of the working fluid.
3D Spatial Heat Transfer
Heat transfer covers radial, axial and spatial heat dissipation, improving heat exchange efficiency.
Diverse Material Options
Features:
Copper tubes: High thermal conductivity (about 385 W/(m·K)), good ductility, and easy to process and form.
Hydrophilic aluminum fins: The surface is treated with hydrophilic process to enhance the diffusion capacity of condensed water, reduce liquid film thermal resistance and improve heat exchange efficiency.
Comprehensive performance: Integrating high thermal conductivity and good corrosion resistance with moderate cost.
Applicable scenarios:
Fresh air systems of commercial buildings under conventional environments, waste heat recovery of hotel air conditioners, etc.
Copper Tubes with Copper Fins
Features:

Applicable scenarios:
Waste heat recovery in humid coastal areas and industrial ventilation systems.
Stainless Steel Tubes with Stainless Steel Plates
Features:
- Stainless steel material: High temperature resistance (up to more than 600℃), corrosion resistance (especially acid, alkali and salt resistance), and high mechanical strength.
- All-stainless steel structure: Avoiding electrochemical corrosion caused by contact between different metals.
- Long service life: Suitable for harsh working conditions, but with relatively low thermal conductivity (about 15 W/(m·K)).
Applicable scenarios:
Waste heat recovery of chemical tail gas, flue gas desulfurization and denitrification and other highly corrosive and high-temperature environments.
