A heat transfer method uses a heat transfer system including: a heat source unit in which heat is exchanged between a heat transfer medium and a heat source; a utilization unit in which heat is exchanged between the heat transfer medium and a temperature adjustment target; and a first flow path and a second flow path that connect the heat source unit and the utilization unit. The heat transfer medium flows through the first flow path from the heat source unit to the utilization unit, and flows through the second flow path from the utilization unit to the heat source unit. In the heat transfer method, inorganic hydrate slurry, in which an inorganic hydrate that absorbs heat when dissolved in water is mixed with water, is used as the heat transfer medium.

A system for reducing evaporative cooling water losses using an electric and magnetic field inducing device is disclosed. The device influences a liquid's properties including evaporation rate, diffusion, vapor, heat transfer rate, and/or fluid properties. The device comprises a malleable core with notches and electrically conductive windings wrapped around the flexible core around the notches. An insulative coating isolates the windings from the core.

A heat pipe is provided for cooling an electronic component of a printed circuit board. The heat pipe includes a tube having an inner diameter surface defining a bore, with the tube having first and second ends along the bore. The heat pipe further includes a sorbent material coated onto the inner diameter surface of the tube, a first liquid contained within the bore, and a second liquid adsorbed by the sorbent material. The second liquid has a second boiling temperature that is higher than a first boiling temperature of the first liquid. The first liquid vaporizes into a first vapor, in response to the tube receiving heat from the electronic component and the first liquid reaching the first boiling temperature. The second liquid is desorbed from the sorbent material and vaporizes into a second vapor in response to the second liquid reaching the second boiling temperature.

A heat exchanger device provides refrigeration in refrigerated vehicles operated by liquefied natural gas (LNG) which must first be regasified. The great temperature difference between heat-discharging cooling chamber air and heat-absorbing LNG evaporating at up to −161° C. conducts the heat flow via an introduced intermediate medium circulating in a closed circuit to avert the risk of combustible natural gas leaking. The intermediate medium is non-combustible, environmentally-benign liquid heat exchange media having low viscosity. The liquid heat exchange media operating temperature is kept above −85° C. using an additional thermal resistance in the heat exchanger which evaporates the LNG, so that the heat flow flows with sufficient temperature drop. A thin protective dry gas layer formed using sheathing tubes enclosing a tubular heat exchanger's tubes coaxially serves as this thermal resistance. Possibly escaping natural gas is determined by monitoring pressure in the layer, and the LNG supply interrupted.

A water-cooling radiator structure with pump includes a pump having a water outlet and a water inlet; and a water-cooling radiator including a first chamber that has a water-receiving room and a plurality of mutually communicable water passages therein. The water-receiving room is filled with a working fluid that reaches a level. The first chamber is externally provided with an outlet and an inlet as well as a pump mounting recess for mounting the pump therein. The water outlet and the water inlet are located corresponding to the outlet and the inlet, respectively, to be communicable with the water-receiving room and located lower than or flush with the level of the working fluid in the water-receiving room. And, the pump is detachably integrated into the water-cooling radiator. With these arrangements, it is able to overcome the problem of failed operation of the pump when the water-cooling radiator is laid horizontally.
