Zulu Nylon Strap

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.

What is Skived fin heatsink?

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.

 As we all know, high temperature is the enemy of integrated circuits.The high temperature will not only cause the system to run unstably, the service lifespan to shorten, but also cause some parts to burn out.The heat that causes high temperatures does not come from the outside , but inside.The role of the heat sink is to absorb this heat keeping the temperature of the computer components normal.

The kind of heat sink is various, CPU, video card, power supply and so on, among which Cpu heat sink can be the most frequently touched .Subdivision of heat dissipation, can be divided into air cooling, heat pipe, water cooling and so on.

Cpu heat sink is one of the necessary accessories in the computer, and plays an inportant role in the system , the current mainstream of the CPU heat sink mode is mainly divided into two categories, one is liquid cold plate, another is air-cooling heat sink. Liquid cold plate includes water cooling, oil cooling, etc., mainly water cooling, and air cooling is a common heat sink with a fan embedded in the heat dissipation, which is the most various and the most commonly used. Water cooling using liquid in the pump driven by forced circulation can take away the heat of the heat sink. Compared to air cooling, it has cooling stability, less dependence on the environment and other advantages.

Generally speaking, water cooling has a better ability than air cooling, but the price is more expensive. And the performance of integrated water cooling heat sink is equivalent to the top air cooling. 

Fan cooling is the addition of a small fan in the led heatsinks. When the LED is lit up, the small fan in the tail also works with the LED. Through the fan, the heat of the aluminum seat is released into the air in the form of air convection.

LED headlight is sensitive to temperature changes. If the LED is continuously lit at high temperature, it will generate more heat. If there is no heat dissipation, it is easy to reduce the power and its lifespan. To some extent, the lifespan of a headlight is directly based on its heat dissipation.

Fan cooling: fan is the active cooling, when the light is lit, the fan of the headlight starts to operate. In terms of structure, the LED headlights of the fan have a compact structure, which can be installed in many vehicles. There is no need to punch holes, and the original structure will not be damaged. Since LED heat sink is generally longer, many vehicle models need to be punched holes on the back cover.

Heat sink cooling: When heat sink cooling works, it needs to reach a certain temperature relying on the natural convection of the air, through the heat sink to the air. Due to the lack of space, the heat sink can not be opened, after the heat sink is installed. And then the cooling system will be effected.
