Simotec Natural Cooling Unit (C-type Pipe Type)

Manufacturer: Shimonishi Giken Kogyo Co., Ltd
Product name: Natural Cooling Unit (C-type Pipe Type)
Overview
This heat sink has fins with unique cross-sectional shapes fixed to a base plate.
It is possible to design the optimum size of the base plate, fin height, number, pitch, etc. depending on the usage environment.
Features
- ・High performance design is possible because tall fins can be created
- – The unique cross-sectional shape of the fins makes them highly rigid and suitable for use in a variety of environments.
- – The main components are made entirely of aluminum, making them resistant to rust and corrosion and suitable for use outdoors or in high humidity environments.
Purpose of use
- Suitable for applications requiring high heat dissipation performance through natural air cooling.
- ・LEDs, communication devices, etc.
