Heat Pipe Assemblies

Heat Pipe Assemblies are highly efficient heat transfer devices. Heat Pipe Assemblies use the phase change process of the working fluid inside the heat pipe (liquid to gas, and then back to liquid) to transfer heat, and have the advantages of high thermal conductivity, low thermal resistance, compact structure, and high reliability. Heat pipe assemblies are widely used in electronic equipment heat dissipation, solar thermal collection, aerospace and other fields.

Kingka Tech Industrial Limited specializes in the supply and production of heat pipe assemblies. Kingka has advanced production equipment and technology, and can customize various specifications and types of heat pipe assemblies according to customer needs. During the production process, Kingka will strictly control the quality of raw materials, use precise processing technology and strict quality inspection to ensure the performance and reliability of heat pipe assemblies.

Heat Pipe Assemblies Processing and Manufacturing Technology

Choose suitable metal materials (such as copper and aluminum) to make the heat pipe shell. Cut the pipe according to the design requirements and clean the surface to remove impurities, ensure that the inner and outer surfaces of the metal pipe are clean, and improve the thermal conductivity.

In order to promote the reflux of the working liquid, a capillary structure is made on the inner wall of the heat pipe. Common methods include:

Metal mesh fixing: attach a fine metal mesh to the inner wall.

Mechanical grooving: a groove-like structure is machined on the inner wall by mechanical processing.

Sintered powder: the metal powder is fixed to the inner wall by a sintering process to form a porous structure and enhance the liquid reflux capacity.

Filling working liquid and sealing

The air inside the heat pipe is evacuated through a vacuum device to form a vacuum environment.

Precisely inject the appropriate amount of working liquid (such as water, ammonia, ethanol) and fill it according to the design requirements.

Use argon arc welding, laser welding or electron beam welding for sealing welding to ensure that the weld is seamless and firm.

Shape Processing and Forming

According to the application requirements, the heat pipe assembly is bent, flattened and other shape processing to meet the equipment installation requirements.

Strictly control the shape change during the processing to ensure that the heat transfer efficiency is not affected.

Tightness Testing

Use airtightness testing (such as helium testing or water pressure testing) to detect the tightness of welds and joints to ensure that there is no leakage.

Use high-precision leak detection equipment to detect the internal vacuum of the heat pipe to meet the design requirements.

Thickness Testing

Use ultrasonic thickness gauges to measure the wall thickness of the heat pipe to ensure that the wall thickness is uniform and meets the design standards.

For components that require high precision, laser thickness gauges can be used to scan different areas to detect thickness consistency.

Finished Product Testing

After completing the above processes, comprehensive tests are carried out, including thermal conductivity testing, durability testing, and stability testing at different temperatures to ensure that the finished product is stable under various environmental conditions.

Through the above processing technology and strict testing methods, Heat Pipe Assemblies can meet the requirements of efficient heat transfer while ensuring that the component structure is tight and the wall thickness is accurate to meet the use requirements of different fields.

The surface treatment of heat pipe components has an important impact on their performance and life. Common surface treatment methods include electroplating, chemical treatment and physical vapor deposition.

Electroplating: A layer of metal (such as chromium, nickel, etc.) is plated on the surface of the heat pipe component to improve its corrosion resistance and surface finish. The electroplating layer can protect the heat pipe component from environmental corrosion, while reducing the adhesion of dirt and improving the heat conduction efficiency.

Chemical treatment: A dense oxide film or passivation film is formed on the surface of the heat pipe component through chemical reaction to enhance its anti-oxidation and anti-corrosion ability. This treatment method is particularly suitable for easily corrosive materials such as aluminum heat pipes.

Physical vapor deposition: High-performance materials (such as titanium carbide, diamond, etc.) are deposited on the surface of the heat pipe component in the form of atoms or molecules to improve its hardness, wear resistance and thermal conductivity. Physical vapor deposition technology can accurately control the thickness and composition of the deposited layer to obtain a surface coating with specific properties.

Heat pipe assemblies have been widely used in many fields due to their efficient and reliable thermal conductivity:

Electronic equipment heat dissipation: Heat pipe assemblies can quickly conduct the heat generated by electronic equipment, maintain the normal operating temperature of the equipment, and improve the stability and reliability of the equipment.

Solar heat collection: Heat pipe assemblies can convert solar energy into thermal energy for heating, hot water and other fields. Its efficient and reliable performance makes the solar heat collection system more stable and efficient.

Aerospace: In the aerospace field, heat pipe assemblies are used for heat dissipation and temperature control to ensure the normal operation and safety of aircraft.

Other fields: Heat pipe assemblies are also widely used in automobiles, ships, chemicals and other fields for heat dissipation, temperature control and heat recovery.

In order to ensure the long-term stable operation of heat pipe assemblies, regular maintenance and care are required:

Cleaning: Clean the surface and interior of the heat pipe assembly regularly to remove impurities such as dirt and dust. You can use a soft cloth or brush for cleaning, and avoid using hard objects or corrosive cleaning agents.

Inspection: Regularly check whether the joints and seals of the heat pipe assembly are intact to ensure that there is no leakage or looseness. At the same time, check whether the exterior of the heat pipe assembly is damaged or deformed.

Replacement: If the heat pipe assembly is found to be damaged or performance degraded, it should be replaced in time. Choose a new assembly with the same specifications and performance as the original heat pipe assembly for replacement to ensure the stability and reliability of the system.

Record: Establish a maintenance and servicing record for the heat pipe assembly, and record the time, content, results and other information of each maintenance and servicing. This helps to timely discover and solve potential problems and ensure the long-term stable operation of the heat pipe assembly.

When using the heat pipe assembly, pay attention to the following matters:

Avoid overheating: Ensure that the heat pipe assembly operates within the allowable operating temperature range to avoid performance degradation or damage caused by overheating.

Avoid corrosion: Select suitable heat pipe assembly materials and surface treatment methods to avoid erosion of the heat pipe assembly by corrosive media.

Correct installation: Install the heat pipe assembly correctly according to the KingKa manufacturer's installation guide to ensure the integrity and reliability of the joints and seals.

Regular inspection: Regularly inspect and maintain the heat pipe assembly to promptly discover and solve potential problems.

Professional repair: If the heat pipe assembly fails or needs repair, please contact a professional repairman or manufacturer for repair. Do not disassemble or repair the heat pipe assembly by yourself to avoid damage or safety hazards.
