Aluminum Skived Fin Inverter Heat Sink With Heat Pipes

    Power inverters are essential components in a variety of applications, including renewable energy systems, electric vehicles and data centers. These devices convert direct current (DC) to alternating current (AC) to power various devices. Due to their high power capacity, power inverters generate a lot of heat during operation, thermal management is critical to ensure the inverters work in high performance. Inverter heat sinks play a vital role in thermal management of inverters, while heat pipe heat sinks are the preferred thermal solutions due to their great thermal  performance.

 

  The inverter heat sink is used to remove the heat from the electronic components of the inverter, a heat sink consists of a metal part with multiple fins attached to the electronic part to increase the contact area. Inverter heat sinks transfer heat to the environment by conduction, convection or radiation. In order to improve heat transfer efficiency, the heat sink should have high thermal conductivity. The heat sink design should be based on the conditions of the inverter and the surrounding environment, there are some factors should be considered when design a good inverter heat sink:

- Rated output power
- ambient air temperature
- Airflow rate
- Thermal resistance of electronic components

   

  To optimize the heat sink design, the thermal analysis should be performed to determine the proper size, shape, material, and TIM of the heat sink.

   

  Heat pipe heat sinks offer significant advantages over traditional heat sink designs. A heat pipe is a hollow cylindrical tube with a vacuum inside, which is hermetically sealed to ensure that no air can enter the tube. Heat pipes work on the principle of phase change, the working fluid is water or other coolant, evaporates at one end and condenses at the other end, the heat absorption of the working fluid at the evaporating end and the heat removal at the condensing end cause a large amount of heat transfer.

   

  Heat pipes allow for more heat transfer than traditional heat sinks because they have an excellent thermal conductivity, with a thermal conductivity of up to 100,000 W/mK, heat pipes are the most efficient way to transfer heat.

   

  The high performance of the heat pipe heatsink comes from its unique design. Heat pipes are made of copper, aluminum or nickel known for their high thermal conductivity. The inside of the pipe is filled with working fluid, which is selected to match its working temperature, pressure and other parameters.

   

  When the temperature of the electronic components rises, the working fluid at the evaporator end evaporates and takes away the heat. The steam transfers heat to the condenser end where it condenses and releases heat. The condensed working fluid then flows back to the evaporator end by capillary in the wick structure.

   

  Heat pipe heat sinks are highly customizable to allow for various configurations including flat, round or triangular. It can be integrated into a power inverter design or installed as a separate component. Heatpipe radiators are lightweight and the ideal solution for applications requiring high thermal performance.

 

Benefits of heat pipe heatsink for power inverters

Heat pipe heat sinks offer several advantages over traditional inverter heat sink designs. These benefits include:

1. High thermal conductivity: Heat pipes have high thermal conductivity and can transfer a large amount of heat from electronic components to the surrounding environment.

2. Lightweight: The light weight of the heat pipe radiator is an excellent solution for applications requiring high mobility.

3. Strong customizability: the heat pipe radiator can be customized according to the output conditions of the inverter and other environmental factors to optimize heat dissipation.
