First Claim
Patent Images
1. An apparatus, comprising:
- an electronically operated device;
a fluid filled conduit, thermally in contact with at least a portion of said heat producing device, and includes a fluid therein;
a pump, of a type that pumps said fluid through the conduit, but does not extend through any outer walls of the conduit to the inside of the conduit; and
wherein said fluid filled conduit includes a first portion forming said thermally contact, and includes a second portion which releases heat.

Abstract
A heat producing device is placed in contact with a heat exchanger that is fluidically coupled to a fluid pump. The fluid pump operates to pumps fluid through a closed fluidic system between the heat exchanger and a spot where the heat can be dissipated. In an aspect, an actuator forces fluid to be pumped without passing through a wall of the pump. One aspect uses an impedance pump as the pumping element.

10. An apparatus, comprising:
-
a chip formed of a substrate with at least one electronically operated device thereon;
a fluid filled conduit, also formed on said chip, and having a first portion which is thermally in contact with at least one portion of said electronically operated device, and at least another portion forming a heat releasing portion; and
a pumping part, operating to pump fluid in the chip without having any portion extending inside walls of said fluid filled conduit. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method, comprising:
-
forming a fluid filled conduit having at least one portion in contact with a heat producing device;
pumping fluid through the conduit without using any part that extends inside walls of the conduit, to draw heat from said at least one portion, and to pump said heat to at least a second portion; and
cooling said fluid at said second portion. - View Dependent Claims (17, 18, 19, 20)
