Abstract: A method for measuring the temperature of a heat pipe includes the steps of: firstly preparing a thermal couple wire formed at one end thereof with a temperature-sensing head, pressing the temperature-sensing head on the surface of the heat pipe to be measured, and a proper amount of a fluid medium is filled between the temperature-sensing head and the surface of the heat pipe. The fluid medium can be water, oil or flowable paste having lower viscosity. Due to the cohesion of the fluid medium, it can fill the gap between the temperature-sensing head and the surface of the heat pipe. As a result, the stability of the thermal contact resistance between the point-contact of the temperature-sensing head and the heat pipe is increased due to the filling of the fluid medium. Also, the contact effect is greatly enhanced to reduce the thermal contact resistance.

Abstract: A bubble cycling heat exchanger includes a closed fluid loop in contact with a heat absorbing source through a heat conducting block. The loop has a bubble generator. An expanding area for generating bubbles is installed at the loop. The loop is also formed with a radiator and a guide region from which bubbles are easily separable. The heat conducting block is connected to the heat absorbing source. Since the overheating of the heat absorbing source will cause the loop to generate bubbles by an unequilibrium formed at the guide region of the loop, the bubbles will separate from the guide region so that the liquid in the loop flows for transferring heat and so that heat is radiated by the fins or other elements of the radiator from the primary element of a computer at the heat absorbing source. The loop operates continuously until a thermal equilibrium is achieved.
