Patent ID: 7054548

Claim:
A heating body cooling device comprising: tubes provided with a plurality of channels in parallel through which fluids flow; and a pump, connected to both ends of the tubes, for causing vibration flows to occur in the fluids, wherein: the tubes have heat absorbing sections for transferring heat of at least a heating body to the fluids and heat radiating sections located on both sides of the heat absorbing section for radiating heat of the fluids to an outside; the fluids vibrate with an amplitude S within the channels so as to transport heat; at least the heating body is arranged at one place in a fluid flow direction; and when a central position of the heating body in a fluid flow direction is referred to as a heating body central position, an end of the heat radiating section on an opposite side of the heat absorbing section is referred to as a heat radiating section front, distances along the fluid flows from the heating body central positions to the heat radiating section fronts are referred to as heat transport distances, and the longer one of the two heat transport distances is referred to as a maximum heat transport distance Lmax, then S>=Lmax holds.
