Product Introduction of Detian Dixing 4D Heat Pipe Heat Exchanger

I. Product Overview

Detian Dixing 4D Heat Pipe Heat Exchanger is a high-end heat exchange equipment upgraded on the basis of the company’s 2D and 3D heat pipe technologies, specially developed for high energy consumption scenarios such as commercial building air conditioning, clean fresh air and industrial ventilation. With 4D reversible heat transfer, zero cross-contamination and non-powered operation as core features, it can efficiently recover cold/heat from air conditioning and ventilation systems and significantly reduce system energy consumption. It is the core equipment for energy saving, carbon reduction and air safety in commercial buildings, data centers, laboratories and medical clean places.
As a core product of a national high-tech enterprise, the 4D heat pipe heat exchanger realizes 4D heat transfer (axial + radial inside and outside the tube) relying on independent patented capillary structure and integrated fin process. The heat exchange efficiency is increased by more than 30% compared with traditional equipment, and the volume is reduced by 20%–30%, balancing high-efficiency energy saving and space adaptation.

II. Core Technical Principles

1

4D Reversible Heat Transfer: Strong capillary force is generated through the special capillary groove structure inside the tube, realizing heat transfer in four directions (axial/radial outside the tube, axial/radial inside the tube). The evaporation section and condensation section can be switched freely, suitable for both winter and summer without reversing mechanism.

3

Phase Change Heat Transfer Cycle: Driven by the temperature difference of cold and hot air flow, the working medium inside the tube completes the closed loop of evaporation → transmission → condensation → capillary backflow. It has no moving parts and no additional energy consumption, with stable and reliable physical heat exchange.

2

Zero-Gap Thermal Resistance Structure: Adopting industrial pure aluminum integrated spiral fin heat pipe, formed inside and outside as a whole, eliminating contact thermal resistance and greatly improving heat exchange efficiency under low temperature difference.

4

Zero Cross-Contamination Isolation: The middle sealing partition and independent flow channel design ensure complete isolation of fresh air and exhaust air, eliminating air cross-flow and cross-contamination, meeting the requirements of high-clean scenes.

III. Core Advantages

Ultra-High Efficiency Heat Exchange

Waste heat/cold recovery efficiency up to 85%, maintaining efficient operation even in low temperature difference environment, reducing air conditioning system load by more than 40%.

Non-Powered & Zero Energy Consumption

Driven only by temperature difference for phase change cycle, no motor or external power supply required, with remarkable annual power saving benefits, and investment can be recovered in 1–2 years.

Long Life & Maintenance-Free

No moving parts and no wear faults. The main body is made of anti-corrosion stainless steel/aluminum alloy, with stable operation for 15–20 years and operation and maintenance cost reduced by 50%.

4D Horizontal Adaptation

Breaking through the installation limitations of traditional heat pipes, supporting horizontal/bedside installation, adapting to narrow spaces such as ceilings and pipe shafts, with flexible installation and convenient construction.

Stable Operation in Full Temperature Range

Operating temperature -40℃~120℃, resisting severe cold and high temperature conditions, with stable and efficient operation in northern winter and southern summer.

Clean, Safe & Compliant

Zero cross-flow and zero pollution, complying with air safety specifications for GMP clean rooms, laboratories, hospitals, animal rooms and other places.
