A laptop computer heat pipe system. A heat pipe is a heat-transfer device that employs phase transition to transfer heat between two solid interfaces. [1]At the hot interface of a heat pipe, a volatile liquid in contact with a thermally conductive solid surface turns into a vapor by absorbing heat from that surface.
The heat sink thermal resistance model consists of two resistances, namely the resistance in the heat sink base, , and the resistance in the fins, . The heat sink base thermal resistance, , can be written as follows if the source is a uniformly applied the heat sink base. If it is not, then the base resistance is primarily spreading resistance:
A finned air cooled heatsink with fan clipped onto a CPU, with a smaller passive heatsink without fan in the background A 3-fan heatsink mounted on a video card to maximize cooling efficiency of the GPU and surrounding components Commodore 128DCR computer's switch-mode power supply, with a user-installed 60 mm cooling fan.
A multi-surface cooler is a sub-type of passive cooler. It allows airflow both between the laptop base and cooler, and between the base of the cooler and the user's lap. These laptop coolers are suitable for laptops that have vents on the underside. The multi-surface cooling design typically works on any surface without blocking any vents.
Microsoft has released service guides for Surface Laptop 7 and Surface Pro 11. [18] iFixit has given both the Surface Laptop 7 and Surface Pro 11 an overall rating of 8/10 on the repairability scale. Noting the improvements over previous Surface devices, the user-removable SSD, and (for the Surface Laptop) the ease of removing the bottom cover ...
The Surface Laptop is a line of laptops marketed by Microsoft, as a sub-brand of their Surface devices. Several models have been produced: Several models have been produced: Surface Laptop (1st generation) , released in 2017
Thermal paste (also called thermal compound, thermal grease, thermal interface material (TIM), thermal gel, heat paste, heat sink compound, heat sink paste or CPU grease) is a thermally conductive (but usually not electrically conductive) chemical compound, which is commonly used as an interface between heat sinks and heat sources such as high ...
Two-phase immersion uses fluorocarbons which boil at low temperatures, transferring heat from the components as a gas. This gas is recovered, condensed by a heat exchanger, and returned to the components. This technique has achieved a PUE of 1.01 [1] and can cool up to 225 kw of heat per rack of servers. [2]
