Special aluminum cooler for passive air cooling of electronic components. This cooler is commonly used for cooling machines as well as electrical and electronic devices. This type of cooling reduces the risk of hardware damage due to overheating. The heat sink features a high number of cooling fins, creating a large surface area that allows for optimal dissipation of generated heat. The principle is simple: the larger the surface area of the cooler, the more heat can be dissipated. This effect is further enhanced by the choice of material, as the high-quality aluminum has good thermal conductivity. The thickness of the cooler base has been chosen to ensure that the heat generated can be quickly dissipated from the component through the cooler. It is recommended to use self-adhesive thermal pads placed between the component and the cooler to enable fast and effective heat transfer. Thermal adhesive achieves the same effect. Since the passive cooler is made of aluminum, it is extremely lightweight and therefore well-suited for applications where weight is a critical factor. Important: It must be noted that the heat sink is made of conductive material and should not come into direct contact with voltage sources. Technical specifications: L x W x H 200 x 120 x 25 mm, material aluminum, number of fins 27, base thickness 6.2 mm, weight 700 g, color matte silver.
