- More than ten times higher thermal conductivity than solid copper - Homogenization of the temperature over the entire surface - Due to the special construction, there is no surface curvature / no puffing and therefore no additional stress on the contacted components. - Temperature range from >0°C – 150°C - Ideal for cooling hot spots
3-D Heat diffuser:
The heat pipe has established itself on the market as a heat conductor for several years. However, heat pipes only conduct heat in an axial direction and can therefore only conduct heat selectively or one-dimensionally without aids such as heat coupling elements. This is where the new 3-D heat diffuser from QUICK-OHM comes in. It enables heat to be conducted in two or three dimensions. The 3-D heat diffuser works like a heat pipe with a two-phase cycle. When a working medium, usually water, evaporates, heat is absorbed by a heat source and given off again by condensation at the heat sink. While a heat pipe has a cylindrical shape and a relatively small diameter, heat can only be transported in the axial direction. Heat diffusers, however, are "surface heat pipes" that can absorb heat at any point and release it to the colder areas.
Due to the more than ten times better thermal conductivity than pure copper, the heat diffuser is very suitable for dissipating heat from hot spots to neighboring components or to other cooling elements such as heat sinks.
The maximum operating temperature must be limited to 150 ° C. Temperatures below 0 ° C should also be avoided, as the heat pipe process cannot start due to the freezing of the water.
The maximum output is basically dependent on the geometry and the temperature level.
For example, a 56x56x3mm heat diffuser can transmit an output of 130W at 70°C.
For individual designs, besides precise calculations, special dies and forms are required, which are usually in the five-digit range. An adaptation of existing forms is not possible.
