Spade Tooth Heat Sink & Integrated Production Of Heat Sink Copper

Customization Pure Copper Heatsink.We provide customers with radiators of various materials, diversified designs and diversified processes, to meet the various needs of customers.

The shovel tooth is the shovel tooth process. The profile is processed into a specific model, such as a radiator fin, with a shovel tooth machine, and the finished product is the shovel tooth radiator.

The shovel-tooth radiator is a long-striped plate profile (aluminum, copper) through mechanical action to cut the material into a sheet shape at a certain angle and straight, and repeated cutting to form a consistent gap structure, which is used to solve the problem under the condition of air cooling and heat dissipation. The heat dissipation of high-power devices can improve the heat dissipation efficiency by 8~15% compared with the plug-in radiator.

Spade tooth heat sinks/radiators are widely used due to their superior performance. With the large-scale application, Tongyu spade tooth heat sink technology and technology are more mature, the degree of automation is gradually improved, and the cost and reliability advantages are obvious. 5G communication, UPS, base stations, charging piles, frequency converters, controllers, wind power converters, SVG, LED lights and other domestic and foreign customers.

The shovel tooth radiator has the following advantages:

        (1) The shovel tooth heat dissipation plate is a whole profile without any connection points, which can give full play to the heat dissipation characteristics of the profile.

        (2) Tongyu's shovel tooth process can make the shovel tooth piece thinner/higher in density, with higher heat dissipation efficiency.
        (3) The processing technology is simpler than Winxuan's other water-cooled liquid-cooled radiators, and the weight is lighter and the cost is lower.
        (4) Compared with processes such as aluminum extrusion, there are fewer restrictions on size and so on, and it can be made wider and can be used for heat dissipation of machines with higher power.

Rslsr-Wx01 Spade Tooth Heat Sink & Integrated Production Of Heat Sink


     Using high thermal conductivity copper material C1100, specification: 2.9*35*52 (mm), a heat sink with 0.1 thickness * 0.22 pitch * 218 teeth is processed, and the accuracy is within 0.01.

        The integrated production of the heat sink has stable heat transfer performance, greatly improved heat dissipation area, heat dissipation efficiency and longer life of heating elements. Products are used in military industry, new energy, communications, servers, industrial computers, large equipment, LEDs and other places that require rapid heat dissipation.

Designers of embedded systems–from boards and modules used in the latest telecom and networking equipment to a variety of cutting-edge designs–face a growing thermal-management challenge. Newer semiconductor devices are dissipating higher amounts of power, so that they run ever hotter and give off more heat within the system.

Because copper has nearly double the thermal conductivity than aluminum, copper heat sinks are much more effective at heat spreading. Copper also has 40% higher heat capacity, meaning devices with transient heat loads or spikes will have better temperature regulation when mated with a copper heat sink.

Nevertheless, copper heat sinks have two notable drawbacks–they're significantly heavier and more expensive than aluminum heat sinks. Fortunately, there is a third option that provides the heat spreading of copper heat sinks, yet is less expensive and significantly lighter. Hybrid heat sinks employ a hybrid copper-and-aluminum construction that combines the advantages of copper and aluminum, providing a superior cooling solution for a wide array of embedded applications.

Product Description

The Skived fin, also known as skiving technology, simply takes an entire piece of aluminum or copper and use special skived machine to cut out fins with standard spacing and a certain thickness and height. Because of using high precision cutting technology, the integration of the forming, relative to other processing technology, the same volume of raw materials can be cut out more heat dissipation area, the heat transfer performance is more stable, in the same condition,the cooling performance is more than 1.5~2 times of the efficiency of traditional bonded fin or soldering heat sink, thus greatly improve heat dissipation efficiency and extend the service life of heating components.

Skived fin heat sink are mainly suitable for industries with high thermal density and high power dissipation requirements, which are widely used in power, medical, communication, industrial control and server industries. With the large-scale applications, skived fins technique becomes more mature and the coverage of this technique has been increased. With the gradual enhancement of the degree of automation, we demonstrate the apparent advantage from the aspects of cost and reliability. We have received the endorsement from various domestic and overseas customers.

The characteristics and advantages:

1. Heat flow analysis, design and development.
2. The optimized combination of copper, aluminum and heat pipe has good heat dissipation effect, which not only satisfies the maximum heat dissipation effect but also fully reduces the cost and has high cost performance.
3. To solve the heat dissipation problem of heat source dispersion and difficult heat conduction.


1. How soon can I get the quotation?

A: Please offer us 2D or 3D drawings (with material, dimension, tolerance, surface treatment and other technical requirement etc.) ,quantity, application or samples. Then we will quote the best price within 24h.

2. What is the MOQ?

A. Usually, we don’t set MOQ, but the more, the cheaper. Besides, we are happy to make prototype or sample for clients to ensure quality standard.

3. DO you provide samples? Is it free or extra?
