CCI02

## CCIC BGA heat sinks 

- Aluminium BGA and compact crosscut heat sinking for a variety of applications requiring simple extension of surface area for cooling. 

- - Typically used with DSP, FPGAs, and other electronics packages. 

- - Double sided adhesive provides simple and effective attachment

## CCI Heat Pipes 

- Copper heat pipes, pure water filled for operation between +5 degC and 110 degC. 

- Various wick structures offered, Screen mesh, Grooved, Sintered and composite (G+S) 

- Low thermal resistance for transportation of heat from hot source to exchanger.  Heat pipe can be incorporate into a block and fix a finned structure (or heat sink) to allow effective heat removal. 

- Thermal resistance of pipe taken at 70degC working temperature (adiabatic), under horizontal orientation, evaporator section 15mm, and condensation section 60mm

## Design Guidelines 

**==> picture [363 x 105] intentionally omitted <==**

**----- Start of picture text -----**<br>
(1) Groove heatpipe<br>condenser<br>heatpipe<br>condenser<br>ev aporator<br>- 90 deg  0 deg<br>evaporator<br>Heat source<br>**----- End of picture text -----**<br>


   - The heatpipe performance is without change from -90 deg to 0 deg. Larger than 0 deg (i.e. evaporator is 

   - higher than condenser), the performance of grooved pipe will degrade 50%. 

- (2) Mesh heatpipe 

**==> picture [303 x 93] intentionally omitted <==**

**----- Start of picture text -----**<br>
condenser<br>heatpipe  evaporator<br>30 deg<br>- 90 deg<br>condenser<br>evaporator<br>Heat source<br>**----- End of picture text -----**<br>


   - Larger than 30 deg, the performance of mesh pipe will degrade 50%. 

- (3) Sintered Powder heatpipe 

      - The orientation has no impact on the sintered powder heatpipe performance.
