Features This product is a cold plate to cool down, and contains semiconductor cooling fins, which are dissipated by a fan, and the cold plate to cool The drop temperature of small products can be directly placed on the cold plate, or holes can be made on the heat sink aluminum, and the cold surface can be directly attached to the surface that needs to be cooled. The contact temperature of the cold sur The heat dissipation method blows from the outside to the inside, and the radiator has air on both sides. If it is placed flat, the bottom needs to be suspended, if used on the side, it needs to keep a good vent This is an advanced semiconductor cooler, come with super power and long-term durability The large-area cooling block has a larger contact area with the air, and the heat dissipation effect is good Specification: Item Type: Refrigeration Cooling System Kit Model: XD-7082 Material: Heat-dissipating aluminum Purpose: Heat dissipation and cooling Power Supply Voltage: 12V Jack Type: Bare wire Cooling Method: Fan cooling Product Size(LxWxH): Approx. 90 x 90 x 75mm / 3.5 x 3.5 x 3in Package List: 1 x Refrigeration Cooling System Kit Note: Remember that this product cannot be directly connected to 220v voltage. If it is connected to the wrong voltage or damaged, please handle it by yourself. No refund or replacement. Package List 1 x Refrigeration Cooling System Kit
