1、 Purpose of Heat Sink selection
The Heat Sink shall be selected by proper and reliable methods to control the temperature of all the electronic components inside the product, so that it does not exceed the max temperature required for stable operation under the working environment conditions, so as to ensure the reliability of normal operation and long-term operation of the product, and avoid the deterioration of the insulation performance of the electronic products; component damage; heat aging of materials; low melting point welds A series of problems such as cracking, solder joint falling off, etc.
2、 Type of Heat Sink
In the fields of wind power converter, power station excitation, locomotive traction, frequency conversion, frequency conversion explosion-proof and photovoltaic inverter, there are many types of Heat Sink used, and manufacturers can also tailor them according to the needs of users.
There are four kinds of Heat Sink in common use: aluminum profile Heat Sink, gravity heat pipe Heat Sink, loop heat pipe Heat Sinkand water-cooled Heat Sink.
The above four types of Heat Sink can also be divided into directional loop heat pipe Heat Sink, loop heat pipe Heat Sink, loop parallel heat pipe Heat Sink, loop profile parallel Heat Sink, gravity heat pipe Heat Sink, profile uniform heat plate Heat Sink, solid profile Heat Sinkand water-cooled Heat Sink.
At present, gravity tube Heat Sink has been widely used in the field of industrial Heat Sink; siphon is mainly distributed in the field of computer heat dissipation due to its capillary structure and high manufacturing cost, which is dominated by miniaturized and integrated products; while loop heat pipe and soaking plate process manufacturing are more complex, so they still stay in experimental research and high equipment.
Up to now, the directional loop heat pipe technology is a cost-effective, effective and economical loop heat pipe technology. The appearance of directional loop heat pipe technology has changed the pattern of heat pipe technology. This technology adopts a more concise and direct way to realize the characteristics of loop heat pipe, and at the same time reduces the production cost. It can reach the price of gravity pipe and the capacity of loop heat pipe, and really bring loop heat pipe technology into our life.
