Water tank is an indispensable part of the whole liquid cooling system, its role is mainly to provide a storage space for water cooling liquid, there is such a space, whether for the addition or discharge of liquid are greatly helpful.
The water cooling heat sink uses the method that stream drives heat of the CPU or the graphics card.
A typical liquid cooling system must have the following components: water-cooled blocks, circulating fluids, pumps, pipes, and water tanks or heat exchangers.
A water-colded plate is a metal block with internal channels, made of copper or aluminum, that comes into contact with the CPU and dissipates the CPU's heat.
Generally speaking, heat pipe heatsink is mostly used for high power heat dissipation. For example, high power cooling panel is the technology that uses heat dissipation substrate buried copper heat pipe and relieving process. Using copper tube can take away heat greater, high-power heat dissipation is different from those often-seen computer heatsinks with 3 tubes and fins.
High-power heat pipe heatsink is generally in the large inlaid copper heat pipe heatsink substrate, and the main technical points on the welding of heat pipe should be paid attention to whether it’s true heat pipe since some of them will be replaced with solid brass, whose performance is comparatively worse than the true one.
Stamping is cold extrusion forming of thin plate, cold forging is below the recrystallization temperature of material forming, hot forging is above the recrystallization temperature of forming for the material. Die casting and injection molding is more like, liquid cooling metal in the mould forming. Aluminum extrusion is the flow of metal through the metal mold when the split extrusion.
The lifespan of the mold is indirectly related to the design of the material used, which can not be generalized. Aluminum extrusion and forging die life is shorter, because the working conditions are terrible.
Generally speaking, aluminum extrusion processing accuracy is higher, while die casting and cold forging are less higher.
High power cooling, Alternative, Greater design flexibility
Skived Fin Heat Sink
· Skived heatsink is a kind of heat dissipation device for electronic components in electrical appliances, mostly made of aluminum alloy, brass or bronze plate,multi-sheet, etc. If it is a side - blown heatsink, then take the chassis internal duct structure into consideration. Or let it blow heat sink directly if you have no idea about it, because general chassis in the level backboard position of CPU heatsinks can have heat sink hole position.
Installation of Skived
· Heatsinks should have a certain mechanical strength and pressure capacity,easy to install and combined into the required cooling area; Size should be small, less take up room area and space; Not easy to damage during installation; The manufacturing process is simple and suitable for mass production.
Zipper fin heat sink features & Materials
Simple mechanical locking structure, fewer procedures; The interface impedance generated by the subsequent connection between the fin and the heat-absorbing base can be compensated; Process quality is relatively stable, suitable for mass production.In order to ensure the stability and tidiness of the combination, the design requirements for the single fin stamping are relatively high.
The importance of heat sink management system
The thermal-related problem of batteries is a key factor of its usage performance, safety, lifespan and cost. First of all, the temperature level of lithium ion battery directly affects its energy and power performance.
When the temperature is low, the available capacity of the battery will decay rapidly. Charging the battery at a too low temperature (less than 0°C) may cause an instantaneous overcharge of the voltage, which will result in internal lithium discharges and a short circuit.
Methods of heat sink
1. Conduction: the transfer of heat from the hotter part of an object to the cooler part.
2. Convection: the transfer of heat by the flow of a liquid or gas.
3. Radiation: Heat released from an object along a straight line.
Heat sink of vehicle batteries
1. Natural Cooling:
In the natural environment, heat was sent into the air by the way of convection and radiation.For example, the previous generation of smart phones were all released into the air by conduction and radiation. Eg. Bga heat sink.
2. Led Cooling:
Eg. Led sunflower heat sink & LED Active Cooling Solutions
3. Air Cooling:
Air convection by fan, eg. Cpu heat sink
4. Liquid Cooling:
Eg. Cold Plate Simulation & Liquid cooling for IGBT&Automotive engine cooling
5. Heat pipe heat sink:
Eg.Desktop CPU heat pipe heat sink& laptop CPU heat sink.
