Title: Composite plate heat pipe
Inventor: AKACHI HISATERU
IPC: F28D15/02
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To provide satisfactory thermal diffusivity and reduce dependence on posture by compositely integrating with a zigzag small-diameter tunnel plate heat pipe having extremely small posture dependence, and mutually interpolating functions of two types of plate heat pipes with one another. SOLUTION: A zigzag small-diameter tunnel heat pipe 2 has satisfactory temperature uniformity to transport heat quantity by an axial vibration of working liquid 5-1. Accordingly, transporting ability is attenuated due to pressure loss in the tube. Then, the pipe 2 lowers its dynamic viscosity coefficient of the liquid 5-1 by heating a temperature lowered part, lowers its pressure loss, and improves heat transporting ability. Particularly, heating of the bent part of the zigzag pipe is extremely effective to largely improve the heat transporting ability. Therefore, the transporting ability is improved by heating the pipe integrated with it by sharp temperature averaging operation of a normal heat pipe 1.

Abstract: PURPOSE:To prevent a blower from shifting and make it safe during its rocking movement with a simple constitution by arranging multiple rollers rotatably under a tail part of a main body and a supporting base at a middle point of the rollers for setting a rocking center point for positioning. CONSTITUTION:With a middle point of multiple rollers 2 arranged rotatably under a tail part 1 of a main body being a rocking center point of a blower, a flange-shaped supporting base 4 is engaged with the lower part of the tail part 1 of the said center point, with the base freely rotatably in horizontal direction. Regarding contact of the supporting base 4 as a rocking center point of the blower with a floor surface 5, the supporting base 4 is set on the floor surface 5 in a manner not to obstruct the rocking movement of the blower but to prevent the blower itself from shifting along the floor surface.
