Feature
Splayed pin heatsinks are relatively new derivatives of the standard pin fin heatsinks. Unlike standard pin fin heatsinks, which contain an array of vertically oriented pins, splayed pin fins features pins that gradually bend outward. Curving the pins in this way increases the spacing between the pins and allows surrounding air streams to enter and exit the pin array more efficiently without sacrificing surface areaThe impact of increased pin spacing on heatsink performance is magnified at lower air speeds because weak air streams have less power to penetrate the array of pins. In low air speed environments and in natural convection, the increased spacing between the pins reduces the heatsinks’ thermal resistance by up to thirty percent versus a standard pin fin heatsink. As a result, splayed pin fins are recommended for low and moderate airspeed environments and for natural convection cooling

Thermal Parameters
The measurements quoted in the heatsink were obtained in Renxin.Thermal laboratories under the following conditionsm,Heatsink anodised matt black and arranged vertically,One heat source(CXB3590) in the centre of heatsink, Temperature measured between the adjacent ,
surface of LED Source and heatsink,
Surrounding temperature measured at a distance of 1 metre (cabinet 1m ) from object , The measurements are stated as temperature increases resulting from power input for different watts . The thermal resistance for the relevant power input is calculated and summarised in an
adjoining curveThese curve demonstrate how the thermal resistance depends on the level of power input.

Installation Instructions
Application
Good grow light modules can be assembled with the best COB chip CXB3590,CXM22,Vero 29, CLU-048 , Heatsinks (95-100 watts) and some standard optical accessories(holder、reflector adapter、reflector or glass lens) . Combined with our special driver bracket, heatsink brackets and hanging kit, those grow light modules can be assembled into a set of professional greenhouse grow lighting projects. This is a smart choice both in terms of costs and time. You won't have to worry about the heating of the grow light at all. Full spectrum will have unexpected benefits to plant growth. We are a professional factory that can help you pre-assemble the kit or provide all the materials you need when assemble by yourself. If you have used some QB288 Quantum board led plant grow light or other lamps that produce a lot of heat, you can throw them all away.
About the performance of the LED Grow lightening products, besides the LED source chip , the heatsink count most. Heatsink of superior quality must be specially designed by the thermal engineers who are responsible for thermal technology and fabricated according to advanced procedures, as well as strictly controlled within quality system requirements and tested according to relevant procedures, so as to ensure superior quality and customer satisfaction. We have accumulated lots of data and Solutions for all of our heatsink during various Solutions, from design to CFD simulating calculation, thermal analysis and optimization. The products can be verified and tested in our own laboratory. All processes including manufacture, testing, packing, and delivering are controlled according to quality system ISO9001:2015,
At present, suppliers on B2B have many small business workshops and Traders , causing malicious competition and bad product quality. Now our products are sold online to ensure the customers can order goods from professional and standard factory. Besides, customers are welcomed to visit our factory
Product packaging
Pin Heatsink Series are packaged in small carton of 1Pieces , 20 pieces samll carton placed inside a big carton, for a total of 20 per carton. Each carton contains 20 Pin Heatsink from the same performance .

Quality
According to the statistics and fault analysis of the LED light industrial association, 63% of the quality issues with lights are related to improper cooling. Choosing a reliable LED chip and Heatsink therefore provides the best guarantee for the service life of LED lights， and also requires discretion of product engineers or product managers. Our professional thermal engineers have more than 10 years' experience in thermal analysis and design, using the world's most advanced LED chips to design and manufacture reasonably priced Heatsink products with the best quality, which have over the years won good reputation and brand image among global customers. Our mission is to enable customers around the world to purchase the best heatsinks directly from our factory via e-commerce platforms, so that their lights will no longer have cooling problems. Customers from all over the world are welcome to visit and inspect our factory.
