LED lights with its energy saving, environmental protection, long life and many other advantages gradually replaced the traditional lighting source. However, LED lights will also produce a certain amount of heat during the working process. If it can not be effectively distributed in a timely manner, it will seriously affect its luminous efficiency, life and reliability. LED heat pipe radiator as an efficient cooling solution came into being, it can effectively solve the heat dissipation problem of LED lights, ensure its stable and efficient operation, for our life and work to bring more bright and lasting lighting experience.

Structural characteristics

Heat pipe structure: The heat pipe of the LED lamp heat pipe radiator is usually made of metal materials with good thermal conductivity such as copper or aluminum, and its shape and size are determined according to the specific heat dissipation requirements. Common heat pipe shapes are round, flat, etc., flat heat pipe has a larger contact area when in contact with the LED lamp board, and can conduct heat more effectively. The parameters of the tube wall thickness, inner diameter and capillary structure of the heat pipe are also carefully designed to ensure that the working medium can smoothly carry out evaporation, condensation and return circulation, and improve the heat transfer efficiency of the heat pipe.

Heat fin: Heat fin is an important part of the radiator. Its material is generally aluminum alloy, with good thermal conductivity and lightweight characteristics. Fins have a variety of shapes, common flakes, wavy, etc. These shapes are designed to increase the contact area between the fins and the air and enhance the heat convection effect. The spacing between the fins is optimized to ensure sufficient air circulation channels, and more fins can be placed in a limited space to improve heat dissipation efficiency. At the same time, the surface of the fin is usually treated, such as anodizing, electrophoretic coating, etc., to improve its corrosion resistance and heat dissipation performance, and make its appearance more beautiful.

Base design: The radiator base is the part that is in direct contact with the LED lamp, and its role is to evenly conduct the heat generated by the LED lamp to the heat pipe. The material of the base is usually a metal with high thermal conductivity, such as copper, and its surface has been precision machined to have a high flatness and finish to ensure good thermal contact with the LED lamp and reduce the contact thermal resistance. The base may also be designed with some fixed structures, such as screw holes, clasps, etc., to facilitate installation and fixing with LED lights to ensure the stability of the radiator during use.

Overall structure compactness: Considering that the application scenarios of LED lights often have certain limitations on space, LED heat pipe radiators pay attention to the compactness of the overall structure in the design. Through the reasonable layout of heat pipes, heat fins and bases and other components, under the premise of meeting the heat dissipation needs, as far as possible to reduce the volume and occupy space, in order to facilitate the installation and use of various types of LED lamps, but also help to reduce the overall weight of the lamp, improve its portability and installation convenience.

Manufacturing process

Heat pipe manufacturing process:

Pipe processing: First choose the appropriate specifications of copper or aluminum pipe, through cutting, stretching, bending and other processes to process it into the required shape and size. In the process of processing, the wall thickness uniformity and inner diameter accuracy of the pipe should be strictly controlled to ensure the stable performance of the heat pipe.

Vacuum and perfusion: the interior of the processed heat pipe is vacuumed to remove impurities such as air and water in the pipe, and then an appropriate amount of working medium is injected in accordance with a certain proportion. The vacuum and perfusion process needs to be carried out in a clean environment, and the purity and perfusion amount of the working medium should be strictly controlled to ensure the normal operation and heat conduction performance of the heat pipe.

Sealing and detection: After the perfusion is completed, the open end of the heat pipe is sealed, usually by welding or special sealing process, to ensure that the working medium will not leak. After sealing, it is necessary to carry out a series of performance tests on the heat pipe, such as thermal resistance test, pressure resistance test, etc., to ensure that the quality of the heat pipe meets the requirements.

Heat fin manufacturing process:

Stamping: The heat fin is generally manufactured by stamping process, and the aluminum alloy sheet is stamped into the desired shape and size by a precision stamping die. During the stamping process, parameters such as stamping pressure, speed and die clearance should be controlled to ensure the shape accuracy, dimensional accuracy and surface quality of the fins.

Surface treatment: The stamped fins require surface treatment, such as anodizing. In the process of anodizing, the fin is used as the anode, and a dense oxide film is formed on its surface through electrolysis in a specific electrolyte. This layer of oxide film can not only improve the corrosion resistance of the fin, but also increase its surface roughness, which is conducive to improving the efficiency of heat radiation and heat convection.

Radiator assembly process:

The fabricated heat pipe and the heat dissipation fin are assembled by welding, riveting or fastening, etc., to ensure a tight connection between the two to ensure that heat can be smoothly transmitted from the heat pipe to the fin. During the assembly process, attention should be paid to controlling the quality of the connection parts to avoid problems such as virtual welding and loosening, which will affect the heat dissipation performance of the radiator.

Assemble the assembled heat pipe fin assembly with the radiator base, and also ensure good thermal contact between the base and the heat pipe. Materials such as thermal conductive silicone grease can be used to reduce the contact thermal resistance. Finally, the overall appearance inspection and performance test of the entire radiator are carried out to ensure that its quality meets the design requirements and use standards.

Performance advantage

Efficient heat dissipation performance: The heat pipe radiator of the LED lamp can quickly conduct the heat generated by the LED lamp and dissipate the heat into the air through the large area of the cooling fin, effectively reducing the working temperature of the LED lamp. Compared with traditional heat dissipation methods, such as natural convection heat dissipation or simple aluminum heat dissipation, the heat pipe radiator has a higher heat dissipation efficiency, which can significantly improve the luminous efficiency and life of LED lamps. For example, in some high-power LED street lamp applications, the heat pipe radiator can control the temperature of the LED chip within a reasonable range, ensuring that the street lamp maintains a stable brightness and color reducibility in the long-term night lighting, reducing the occurrence of light decay, thus extending the maintenance cycle and service life of the street lamp.

Good temperature uniformity: The working principle of the heat pipe enables the heat to be transferred quickly and evenly inside it, thus ensuring the overall temperature uniformity of the radiator. This is very important for LED lights, because LED lights are more sensitive to the uniformity of temperature, if the local temperature is too high, it will lead to the LED chip's luminous efficiency being inconsistent, and even local overheating damage. The heat pipe radiator can effectively avoid this situation, so that all parts of the LED lamp can work at a relatively uniform temperature, and improve the luminous quality and stability of the LED lamp.

High reliability: LED lamp heat pipe radiator after strict manufacturing process and quality testing, with high reliability and stability. Its structure design is reasonable, can withstand a certain degree of mechanical vibration and impact, is not easy to loosen, deformation or damage and other problems, suitable for a variety of complex working environments. For example, in outdoor lighting applications, LED heat pipe radiators can resist the impact of harsh natural conditions such as wind, rain, and sun exposure to ensure the normal operation of LED lights, reduce the incidence of failure caused by heat dissipation problems, and reduce maintenance costs and repair workload.

Strong adaptability: Due to its compact structure and efficient heat dissipation performance, the LED lamp heat pipe radiator can adapt to the heat dissipation requirements of different powers, different sizes and different shapes of LED lamps. Whether it is a small indoor LED spot light, bulb light, or a large outdoor LED display, street lamp, etc., you can choose the appropriate heat pipe radiator model and specification according to the specific heat dissipation requirements, to achieve personalized heat dissipation solutions, and provide strong support for the diversified applications of LED lights.
