Computer Processor Fins

They also found that smaller Aluminum fins, tightly packed radiate heat faster than larger fins, due to energy retention of the larger fins. The only stipulation for a heatsink design is that it must be able to cool a CPU with a certain wattage dissapation and keep it within temperature specs.

continuous and discontinuous heat sink installed at North Bridge and at CPU main processor in computer system and discontinuous heat sink proposed for geometrical and cost effective material optimization. It has been observed that the interrupted fins exhibit a thermal boundary layer interruption which helps increase the heat transfer rate.

Computers and Laptops In computer processors outside the thermal envelope, computer chips regularly use heat sinks to cool them. LED Lighting Heat sinks in LED lighting are used to dissipate heat produced by the LEDs which would otherwise shorten the life of the light.

Heat pipes are made to move the heat quickly away from the cpuGPU and to the fins. As it passes through the fins they take the heat and pass that onto the air at a speed based on surface area. Yes the pipes give off heat, but if tue heat is spread out it can go faster. Think of it like evaporating water.

last few years, as the processors got more and more powerful, it has become mandatory that a CPU requires a multi-fin heat sink as well as a fan that ensures reasonable air flow through the cooling fins as the overheated processors exhibit a shorter maximum life span and often results in problems like system freezes or crashes.

computer processors and power supplies and industrial applications such as heat exchangers and substation transformers Fins Extended surfaces or Fins are generally used to enhance convective heat transfer rate between a solid and the surrounding fluid. Simply put A fin extends the surface area of heat transfer. Micro processor fin fan

A fan-cooled heat sink on the processor of a personal computer. To the right is a smaller heat sink cooling another integrated circuit of the motherboard. Typical heatsink-fan combination found on a consumer laptop. The heatpipes which contain a working fluid make direct contact with the CPU and GPU, conducting heat away from the component and transferring it to the fin-stack mounted on the

Initial temperature of the fin and the base was kept at 100C, which is usually a thermal threshold for daily use microprocessors. The boundary condition at the base was 100C., with the fins subjected to convection with either of the fluids. Figure 1 Schematics of four fin design variations used in the study. All the designs have the same

Internal temperature The CPU itself surface area of 10mm x 10mm reaches a max of 80 degrees. Surface area of the enclosure 0,05735 m2. Enclosure material Aluminium sheet metal 1mm thickness Space between CPU and inside of the enclosure 14mm. Maximum Volume of the Heatsink 60cm3

However, for the last few years, as the processors got more and more powerful, it has become mandatory that a CPU requires a multi-fin heat sink as well as a fan that ensures reasonable air flow through the cooling fins as the overheated processors exhibit a shorter maximum life span and often results in problems like system freezes or crashes.
