  • Publication number: 20090114876
    Abstract: An antifreeze composition comprising one or more metal chlorides, in particular, calcium chloride and magnesium chloride, and a solution having an alkaline pH in which at least one of the following ions is dissolved: Bromide (Br?), Bicarbonate (HCO3?), Borate (BO33?), Silicate (SiO3?), Fluoride (F?), Iodine (I?). this composition is capable of providing an effective antifreeze action, for example on roads, airstrips and vehicle windows, also in conditions of extremely cool temperatures. In fact, the composition remains in the liquid state even at very low temperature reducing, in particular, the environmental impact with respect to the solutions of prior art. This is possible because the interaction existing between a metal bivalent ion 10, such as Ca2+, or Mg2+, and a chloride ion (Cl?) 20, in the antifreeze composition brings the ions at a high balancing distance “R”. This is due to the presence of at least one weak ion 15, for example Bicarbonate (HCO3?), Borate (BO33?), Iodine (I?), Fluoride (F?), etc.

  • Patent number: 7381346
    Abstract: A thermal interface material is for being applied to the contact surfaces to eliminate the air interstices between the heat dissipating apparatus and the electronic component in order to improve heat dissipation of the electronic component. The thermal interface material includes pentaerythritol oleate as base oil and fillers filled in the pentaerythritol oleate for improving the heat conductivity of the thermal interface material. The pentaerythritol oleate is used for holding the fillers therein and filling the air interstices to achieve an intimate contact between the heat dissipating apparatus and the electronic component. The fillers include aluminum powders, zinc oxide powders and zinc oxide nano-particles.

  • Patent number: 7374698
    Abstract: A nanometer heat-conducting water solution for use in a car cooling system is disclosed. The nanometer heat-conducting water solution is formed by mixing a AlO2 solution (1.1 vol %) having 3-10 nanometer scale materials with a TiO2 solution (1.1 vol %) having 3-10 nanometer scale materials, wherein the obtained solution is then mixed with a diluent (93 vol %), and dispersing agents (3.43 vol %) and an emulsifying agent (1.37 vol %) are thereafter added so as to disperse the AlO2 solution and the TiO2 solution in the diluent uniformly. When the obtained stable nanometer heat-conducting water solution is added to a water tank of the car, the TiO2 cleans limescale and the emulsifying agent adheres to wall surfaces of water jackets to allow AlO2 to release energy continuously. Moreover, the nanometer scale materials speed up the micro-explosion of the cooling water so as to optimum the cooling effect and increase the heat-dispersing efficacy significantly.

  • Patent number: 7320770
    Abstract: The process according to the invention includes the combination, with a liquid phase change material (PCM), of a texturing agent chosen so as to greatly reduce the thermal convection and whose viscosity is decreased reversibly under shearing. The material formed has a gelled consistency when at rest, and fluidized under shearing. The PCM comprises a mixture of chemical compounds from the alkane family: paraffins, waxes, fatty alcohols, fatty acids etc., and the texturing agent is a high mass polymer (hydrocarbonate polymers, ester or ether polymers, mixed ester-hydrocarbon polymers), an ionomer polymer or a di, tri or multi-block styrene copolymer (SBS: styrene-butadiene-styrene, SEBS: styrene-ethylene-butadiene-styrene). Applications: thermal insulation of vessels or lines, and more especially, for hydrocarbon transport lines.

  • Patent number: 7309453
    Abstract: A coolant capable of enhancing corrosion inhibition includes a potassium formate solution having a first concentration of a polyphosphate salt and a second concentration of dicyandiamide. In one embodiment, such a coolant may provide corrosion inhibition that is especially effective for silicon and aluminum, among other materials. The corrosion protection may be enhanced for certain materials by adding benzotriazole in a third concentration to the potassium formate solution.

  • Patent number: 7309451
    Abstract: A deicer comprises a mixture of a deicing agent and a radiation absorber. The radiation absorber results in an increased ice-melting capacity than using the deicing agent alone. The deicer can include a deicing salt such as sodium chloride, and the radiation absorber can include a dye, which can be water soluble. The deicer can also include a corrosion inhibitor and/or wetting agent. Further, a method of making a deicer includes mixing a deicing agent and a radiation absorber. The radiation absorber can be dissolved in a liquid, such as bittern, which can be sprayed on a solid deicing salt.
