Abstract: A heat storage device includes a heat storage, a first flow passage, a second flow passage and a flow rate regulator. The heat storage stores heat released from coolant. The first flow passage is placed in a circulation path that conducts the coolant. The heat storage is installed in the first flow passage. The second flow passage conducts the coolant and bypasses the heat storage. The flow rate regulator adjusts a flow rate ratio that is a ratio of a second flow rate of the coolant, which flows in the second flow passage, relative to a first flow rate of the coolant, which flows in the first flow passage. The flow rate regulator reduces the first flow rate when a temperature of the coolant is decreased.

Abstract: A magneto-caloric-effect element has a plurality of element units. The element units have lengths, respectively. The element units have different Curie temperatures, respectively. The element units demonstrate magneto-caloric effects. Two adjoining performance distribution crosses at a cross temperature. A temperature in the rated operational status between two adjoining element units is called a boundary temperature. The lengths and/or Curie temperatures are set so that the boundary temperatures and the cross temperatures coincide each other. Thereby, a plurality of element units can function at high effectiveness in the rated operational status.

Abstract: A vehicle thermal management system includes a vehicle driving battery that generates heat during charging and discharging and a liquid heat transfer medium that transfers the heat received from the battery. The system further includes a heat receiver that causes the heat transfer medium to receive the heat and a refrigerant heat exchanger that causes the heat transfer medium to release the heat. The heat transfer medium includes a liquid base material including water and an orthosilicic acid ester compatible with the liquid base material and does not include an ionic rust inhibitor. The orthosilicic acid ester is present, as a concentration of silicon, relative to a total mass of the heat transfer medium within a range between 1 mass ppm, inclusive, and 2000 mass ppm, inclusive or within a range between 2000 mass ppm, non-inclusive, and 10000 mass ppm, inclusive.

Abstract: During a normal operation, a refrigeration cycle device is switched to a refrigerant circuit in which heat contained in a high-pressure refrigerant flowing out of an interior radiator is stored in a heat storage member. When frost is formed on an evaporator, the refrigeration cycle device is switched to another refrigerant circuit in which the exterior heat exchanger is heated and defrosted using heat stored in the heat storage member as a heat source. The heat storage member uses a material formed by adding W (tungsten) as an additive to VO2 (vanadium dioxide) which is a transition metal oxide having a property of a phase transition between a metal and an insulator. The heat storage member effectively stores or dissipates heat depending on a temperature zone of the refrigerant, thereby suppressing an increase in energy consumption of a compressor.

Abstract: A heat transfer system has an energy converter, a heat transfer medium, a transfer part, and a heat exchanger. The energy converter converts an energy of an energy source into an energy in a different state and generates a heat while converting the energy. The heat transfer medium is in a liquid state and receives the heat from the energy converter. The heat exchanger dissipates the heat from the heat transfer medium to an outside of the heat transfer system. The heat transfer medium contains H2O and a solute compatible with the H2O. The solute has a molecular structure including two hydroxyl groups. A length of a binding chain between an oxygen atom of one of the two hydroxyl groups and an oxygen atom of an other of the two hydroxyl groups is shorter than a length of a binding chain between two hydroxyl groups of an ethylene glycol molecule.

Abstract: A heat storage system has a heat source that generates heat and radiates the heat to a first heat medium and a heat storage body that stores heat. The heat storage body changes to a first phase in a solid state when a temperature of the heat storage body is lower than or equal to a phase transition temperature, and changes to a second phase in a solid state when a temperature of the heat storage body exceeds the phase transition temperature. The heat storage body stores or radiates heat due to a phase transition between the first phase and the second phase. A heat storage mode in which the heat storage body stores heat of the first heat medium and a heat radiation mode in which the heat storage body radiates the heat stored in the heat storage body to a heat transfer target are switchable.

Abstract: A heat transfer medium is used for a heat transfer system including a refrigerant cycle device through which a refrigerant circulates and a heat transfer medium circuit having a cooling target device. The heat transfer medium is cooled through heat exchange with the refrigerant and absorbs heat from the cooling target device while circulating through the heat transfer medium circuit. The heat transfer medium includes a carboxylate aqueous solution formed by dissolving carboxylate in water. Accordingly, by using the carboxylate aqueous solution as the heat transfer medium, a low viscosity at a low temperature can be secured. Further, since the carboxylate aqueous solution has a high heat exchange efficiency, the cooling capacity of the heat transfer medium can be improved.
