Class / Patent application number | Description | Number of patent applications / Date published |
123410140 | System drained and/or heat-storing | 9 |
20080245319 | Heat storage tank - A heat storage tank | 10-09-2008 |
20090205590 | Engine cooling system with overload handling capability - A cooling system for an internal combustion engine incorporating a heat accumulator to temporarily store heat during peak heat loads. In automotive vehicles, the heat accumulator may store excess heat generated during vehicle acceleration or hill climbing and it may dissipate stored heat during vehicle cruise, deceleration, or engine idle. The heat accumulator contains phase change material with a solid-to-liquid transition temperature higher than the normal operating temperature of the cooling system. The invention enables reducing the size and weight of engine cooling system without compromising its performance. This is particularly important for improving fuel economy and reduction of emission in automotive vehicles. In addition, the invention enables reducing the coolant inventory in the system thereby allowing for faster engine warm-up and reduced emissions of harmful pollutants during a cold engine start. The invention may be also used for thermal management of engine oil, transmission fluid, or hydraulic fluid. | 08-20-2009 |
20090288617 | HEAT STORAGE SYSTEM FOR VEHICLE - In a heat storage system for a vehicle including a heat accumulator S, in which engine coolant is stored and allowed to flow, in an engine coolant circulation circuit connecting an engine ENG and a heater core | 11-26-2009 |
20100126437 | HEAT RECOVERY SYSTEM - The present invention is directed towards methods and systems for heating an engine, particularly during initial start-up of the engine. In one exemplary embodiment, a heat storage and release system for an engine is provided. The system may include a material capable of super cooling within an operating temperature range of the engine. The material is in thermal communication with the engine and may include an energy input device associated with the material. The energy input device may be configured to input energy to the material causing the material to undergo an exothermic phase change. During the phase change the material releases heat to the engine. | 05-27-2010 |
20100162972 | Heat Storage Apparatus and Engine Including the Same - In the cylinder block of an engine including a heat storage apparatus, a water jacket is formed between a cylinder bore wall that forms a cylinder bore and a cylinder block outer wall. An actuator is installed on the cylinder block outer wall. A container is housed in the water jacket. A coolant temperature sensor is installed on the upper portion of the container. An ECU determines the state of a heat storage agent in the container and the state of the container, based on information on the temperature of coolant determined by the coolant temperature sensor. | 07-01-2010 |
20130146000 | Heat Storage Device of Vehicle - A heat storage device of a vehicle may include an insulation container, a coolant passage connected to an engine, a heat exchanger having a fin formed on the coolant passage inside the insulation container, a phase change material charged in the insulation container to exchange heat with flowing coolant, a phase change material temperature sensor, a pressure sensor, an engine coolant temperature sensor, and a control portion that circulates the coolant according to the driving condition of the engine and the coolant temperature such that the coolant exchanges heat with the phase change material. Accordingly, fuel for warming an engine or heating an interior room is reduced, a separate heating device or a warm up device such as a PTC heater can be replaced, quality of the exhaust gas is quickly improved, and there is a merit in overcoming environmental regulations. | 06-13-2013 |
20130255602 | FLEXIBLE HEAT ACCUMULATOR FOR ENGINE COOLANT - A heat accumulator for a vehicle engine, comprising storing coolant in a flexible storage container with an inner body and an outer body, with an insulation device arranged between the bodies, and an inflow and an outflow for the coolant wherein the storage container can expand and deflate in response to the amount of coolant stored. The flexible storage container allows for the heat accumulator to conform to various under hood space constraints. | 10-03-2013 |
20140331946 | HEAT ACCUMULATOR - A heat accumulator for use in a motor vehicle having a heat accumulator container which can be integrated into the motor oil circuit, through which motor oil flows when the motor is running, and which is disconnected from the circuit when the motor is switched off. The oil pan of the motor, in particular the lower part of the oil pan, is provided as the heat accumulator container, and the oil pan is provided with heat-insulating container walls. Also, an element for increasing the heat capacity of the heat accumulator is provided. | 11-13-2014 |
