High Power IGBT Aluminium Heat Sink
High Power IGBT Aluminium Heat Sink
Motor controller Insulated Gate Bipolar Transistor (Insulated Gate Bipolar Transistor, the IGBT) heat dissipation performance increasingly become motor IGBT now entering the industrial power electronics market, such as (welding) heat sink, traction inverter, motor drive, etc. Ruiqifeng provides IGBT heat sink assembly products that allow IGBT to work at a higher temperature enclosure while keeping the working junction temperature within a safe range by combining low thermal resistance with Vce(on) silicon.
IGBT in most cases works with a high power device, high power means higher heat dissipation, IGBT is toward large capacity, high frequency, easy to drive, low loss, modular, points out the direction of development, compared with other power electronic devices, IGBT heat sink has high reliability, simple drive, easy to protect, there is no buffer circuit and switching frequency is high, so the IGBT heat sink in the electronic market becomes very necessary. In order to achieve these high performances, many processes are used in integrated circuits, such as epitaxy, ion implantation, fine lithography, etc. In recent years, the performance of the power IGBT module heat sink has been improved rapidly, the rated current has reached hundreds of amperes, the withstand voltage of more than 1500V, and is still improving. Since IGBT devices have positive characteristics of the PIN diode, the characteristics of the p-channel power IGBT module heat sink are not much different from that of n-channel IGBT, which is very conducive to adopting a complementary structure in the application, thus expanding its application in the field of ac and digital control technology. The biggest advantage of IGBT is that it can withstand current shock in either an on or short circuit state. Its parallel connection is not a problem and its series connection is easy due to its short shutdown delay.
IGBT heat transfer modes usually include air cooling, water cooling, copper heat sink or aluminium heat sink. Its heat dissipation is based on the basic principle of heat transfer, a heat flow path with the lowest thermal resistance is designed for the device so that the heat emitted by the device can be emitted as soon as possible, so as to ensure that the internal junction temperature of the device is always kept within the allowable junction temperature.
At present, the existing IGBT heat pipe heat sink in the market mainly includes heat dissipation fin, heat pipe and substrate, on which the substrate is provided with a number of parallel grooves, and then the groove is welded with solder to the evaporating section of the heat pipe. In the existing IGBT heat pipe heat sink technology, the evaporating section of the heat pipe is buried in the groove of the substrate and does not directly fit the IGBT surface. In the working process, the heat from the IGBT surface is firstly exported through the substrate and then transferred to the heat pipe and heat sink. Finally, the heat from the heat sink is transferred to the air by convection. Because the substrate itself has thermal resistance, and the thermal conductivity coefficient of the heat pipe is much higher than that of the base, the thermal conductivity efficiency of the heat pipe heat sink is limited, and the heat dissipation performance is reduced. IGBT heat sink can transfer the heat evenly from the substrate to the fin, which can effectively solve the heat dissipation problem of high heat flux, not only with high efficiency but also with a compact structure and no moving parts, which can truly realize maintenance-free.

IGBT heat sink with heat pipe
Product Details
This IGBT heat sink with heat pipe mainly included heat sink fin, heat pipe and base, wherein the base is provided with a number of mutually parallel grooves, the grooves are then soldered with solder to the evaporating section of the heat pipe
In the existing IGBT heat sink with heat pipe technology, the evaporating section of the heat pipe is buried in the base groove, which does not directly fit with the base of IGBT. During the IGBT working process, the heat on the surface of IGBT is firstly dissipated through the base, and the heat then transferred to the heat pipe and heat sink fin. Finally, the heat is transferred to the air by convection through the heat sink fins.

Surface Treatment For Aluminum Profile
Aluminum has various features such as being strong, and easy to process. Aluminum is a metal that is used in many fields, and its performance can be further enhanced by surface treatment.
A surface treatment consists of a coating or a process in which a coating is applied to or in the material. There are various surface treatments available for aluminum, each with its own purposes and practical use, such as to be more aesthetic, better adhesive, corrosion resistant, and so on.

The common use package of aluminum profiles
1. Ruiqifeng Standard Packing:
Stick the PE protective film on the surface. Then the aluminium profiles will be wrapped into a bundle by the shrink film. Sometimes, the customer asks to add a pearl foam inside cover the aluminium profiles. Shrink film can have your logo.
2. Paper Packing:
Stick the PE protective film on the surface. Then the number of aluminium profiles will be wrapped into a bundle by the paper. You can add your logo to the paper. There have two options for paper. Roll of Kraft paper and straight Kraft paper. The way of using of two kinds of paper is different. Check the picture below you will know it.
Roll Kraft Paper Straght Kraft Paper
3. Standard packing + Cardboard box
The aluminium profiles will be packed with the standard packing. And then pack in the carton. Last, add the wooden board around the carton. Or let the carton load the Wooden pallets. 
With Wooden Board With Wooden Pallets
4. Standard Packing + Wooden Board
First, it will be packed in standard packing. And then add the wooden board around as the bracket. In this way, the customer can use the forklift to unload the aluminium profiles. That can help them save the cost. However, they will change the standard packing to reduce the cost. For example, they just need to stick to the PE protective film. Cancel the shrink film.
Here are a few points to note:
a. Every wooden strip is the same size and length in the same bundle.
b. The distance between the wooden strips must be equal.
c. The wooden strip must be stacked on the wooden strip when loading. It cannot be directly pressed over the aluminium profile. This will crush and smear the aluminium profile.
d. Before the packing and loading, the packing department should calculate the CBM and weight first. If not it will waste much space.
Below is the picture of the correct packing.
5. Standard Packing + Wooden Box
First, it will be packed with standard packing. And then pack in the wooden box. There also will have a wooden board around the wooden box for the forklift. The cost of this packing is higher than the other one. Please notice that there must have foam inside the wooden box to prevent the crash.
The above is just the common packing. Of course, there are many different packing ways. We appreciate hearing your requirement. Contact us now.
