| <Circulation Pump> |
|
|
| Eamex has developed a diaphragm pump based on
the powerful PPy actuator. |
|
|
| <Characteristics> |
・A pair of diaphragms itself actuates (No need
for electric motors)
・No vibration or noise
・Contamination of bubbles does not obstruct circulation
・Capable of sucking
・Small and/or light
・Low drive voltage (1.5V)
・Small number of parts and low cost

| <Principle of pumping mechanism> |
| The diaphragm pump repeats
alternate suck and discharge by applying alternate voltage to the two
CP actuator films, and liquid continuously circulates in the circuit.

<Oscillation Pump> |
| Combination between the heat pipe and the EAMEX diaphragm type oscillation pump (oscillator) improves considerably the heat transportation of the heat pipe. Three times larger the maximum heat transportation is achieved by using a small oscillator to move water in the heat pipe back and forth. The massive improvement in the heat transportation of the heat pipe enable to solvethe heat problem of portable PC's. |
<Characteristics>
*Three times higher cooling ability than that of conventional heat pipes
*No vivration / Noiseless
*Small and light
*Low drive voltage (1.5V)
*Small number of parts / Low cost
