Heat-dissipating device and heat-dissipating system

Abstract

A heat-dissipating device and a heat-dissipating system are provided. The heat-dissipating system includes a driver, a heat-exchanger and a heat-dissipating device. The heat-exchanger is communicated to the driver and includes a body, a hydrophobic membrane and a cover. The body has an inlet, an outlet and a channel. Both ends of the channel exposed on a body's surface are respectively communicated to the inlet and the outlet, the inlet and outlet are communicated respectively to the driver and heat-exchanger. The membrane is disposed on the body's surface and covers the channel. The cover combines with the body and has a chamber and an exhaust port. The membrane separates the channel from the chamber communicated to the exhaust port communicated to the heat-exchanger. The driver drives a working fluid to the heat-dissipating device, and the fluid further goes to the heat-exchanger from the heat-dissipating device and then back to the driver.
