Baiwu, with a width of 239mm or less, can be used. The amount of splicing plate can be changed freely according to the size of the plateIt is light and does not block your hand. When you connect , you can down. High semiconductor black technology specially sets an conditioner for your favorite machine.So that the heat of the mobile phone can escape 35mm contact areaExquisite cold conduction process, electroplating process, embedded scratch resistant layer and pattern, aluminum sheet with electric heating coefficient of 237w / (m.k) can quickly gather cold and evenly diffuse to absorb the heat of mobile phone, and the thermal conductivity of liquid water (about 0.59w / (m.k))The materials and details of the product are strictly controlled, and cold and hot partitions are used on both sides of the semiconductor to block consumption. The 9-blade fan is optimized and upgraded, with a speed of up to 7000 rpm. The daily fan speed is about 4000-5000 rpm. The strong speed supplies to the heat dissipation aluminum column and brings out the semiconductor heat from multiple heat dissipation sealsRated of fan: 5WCharging input: 5V / 1.7VCharging interface: type-CApplicable model: width below 239mmFeature 1: radiatorFeature 2:Mobile phone radiatorFeature 3: Cooling back Feature 4:Mobile phone cooling fanColour:blackMaterial:ABS Size:23.9 x 6.5 x 3.4cmPackage Contents:1 x radiator1 x charging cableOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
