Many people think of the heat sinks used in computer CPUs and graphics cards. This is a radiator that only some high-end players can use, because it is more expensive. In the field of industrial electronics, water cold plate or liquid cold plate has also been widely used, but the public does not know much about it, and many high-power equipment will choose water-cooled heat dissipation solutions.
SVG, inverters, inverters, IGBTs, APFs and other high-power devices that are widely used in many industries. These devices can use water cold plate for heat dissipation, and the heat dissipation effect is very good. winshare thermal has long-term research and design. The water-cooling solution of such equipment radiators provides users with high-quality water-cooled flat-plate radiators.
The water cold plate and the air-cooled heat sink are essentially the same, but the principle of the water cold plate is to use a circulating fluid to transfer the heat of the equipment from the water-cooled module to the heat exchanger, and then perform the heat dissipation air-cooled homogeneous metal or heat pipe , The heat exchanger part is almost a replica of an air-cooled radiator.
The water cold plate can be effectively divided into active water cooling and passive water cooling during use. In addition to all the accessories of the water-cooled heat sink, active water cooling also needs to install a cooling fan to assist in heat dissipation, which can greatly improve the heat dissipation effect. Passive water cooling does not install any cooling fans, and only relies on the liquid cold plate itself to dissipate heat. Some heat sinks are added to assist the heat dissipation. This water cooling method is less effective than active water cooling, but it can achieve a completely silent effect.
1. Look at the material. Most of the water-cooled heat sinks of the radiator on the market are designed with aluminum plates buried in copper pipes. This type of water-cooled plates using aluminum and copper alloys is cost-effective and relatively low in cost. It is not difficult for everyone to look at the quality of aluminum and copper, whether there are impurities, that is, the quality of the raw materials.
2. Look at the craftsmanship. The material can be the same but the process is different, but the effect of the radiator is completely different. The process must be started from two aspects. On the one hand, whether the production is carried out according to the design drawing. The parameters indicated in the drawing are checked with a vernier caliper. The error is It can be regarded as qualified if it is within 0.05 mm, and the accuracy can be up to 0.02 mm if the requirement is high.
