Abstract
A heat storage device for an automobile engine is designed according to the problems of being difficult and time-consuming to start engine, polluting environment and being harmful to the engine when starting the automobile engine in the case of low temperature. The storage device is mainly a cooling medium loop which comprises a circulating pump, a heater, a three-way control valve and a heat accumulator. The recycling of the cooling medium and the heat storage and heat emission of the heat accumulator can be controlled via a temperature sensor and a temperature control relay, therefore making the engine instantly start up in the case of low temperature and making the temperature inside the automobile rapidly raised. The heat storage device can be widely used for various automobile engines which run in open air in cold area and can be used in other projects and transport machinery of outdoor work.
Description
The utility model belongs to the motor car engine heat-stored device of the improved engine cold-start performance of using on the motor.
The cold start-up of motor car engine is a difficult problem at outdoor operation motor always.Because under the environment of cold,,, exist still that temperature rise is slow, starting time is long because the temperature of motor is lower though used antifreeze liquid and non-congealable oil; Fuel combustion is incomplete, befouling environment; The wearing and tearing of engine cylinder-body are bigger, reduce the shortcomings such as working life of motor.If in the low especially occasion of temperature, the startup of motor is just more difficult.
The utility model is the motor car engine heat-stored device of developing at the problem that exists in the existing motor car engine cold start-up.
The utility model is realized by following measure.Mainly form, it is characterized in that: by a motor car engine cooling medium loop of forming by recycle pump, distributing T-pipe control valve and thermal accumulator by motor, recycle pump, control valve and thermal accumulator; The cooling medium outlet of motor is connected with recycle pump, and outlet of circulating pump is connected with the cooling medium inlet of distributing T-pipe control valve; A cooling medium outlet of three-way valve is connected with the cooling medium inlet of thermal accumulator, and the cooling medium outlet of another cooling medium outlet and thermal accumulator is connected with the cooling medium inlet of motor together; On the cooling medium input circuit of thermal accumulator and output loop a temperature transducer is set respectively, two temperature transducers are connected with thermorelay, and the output terminal of thermorelay is connected with the distributing T-pipe control valve.In the housing of thermal accumulator thermal insulation layer, be a cooling medium heat exchange chamber, adorn the heat accumulation sheet of solid-state heat-storage medium in being arranged at intervals with in the chamber; Heat exchange chamber is divided into two chambers by dividing plate, and an end of two chambers communicates, and the other end is equipped with cooling medium supplying tube and cooling medium output tube respectively.The accumulation of heat loop of engine cooling medium is provided with warm-air drier.
When engine operating temperature raises, make the cooling medium of high temperature flow through thermal accumulator by recycle pump, the solid-state heat storage medium heat absorption in the thermal accumulator is melted, and finishes accumulation of heat.When motor needs cold start-up, make recycle pump work by connecting ignition switch (car key).Three-way valve is connected cooling medium major cycle loop (motor, recycle pump, control valve, thermal accumulator, motor), and thermal accumulator begins heat release.Low-temperature cooling media in the motor is replaced by the high temperature cooling medium in the thermal accumulator, and the temperature of motor raises, and can normally start.After the heat-stored device heat release was finished, cooling medium short circle loop (motor, recycle pump, control valve, motor) was connected in the closed major cycle of three-way valve loop.When motor reached operating temperature, the low-temperature cooling media in the thermal accumulator was blended in the cooling medium in the circulation discontinuously by the control of control valve.Playing cooling medium this moment flows through from thermal accumulator all the time.The conversion of three-way valve medium circulation is to realize by the temperature signal of temperature transducer and thermorelay.Behind tail-off, heat-stored device worked on about 15 seconds, under the control of thermorelay, made thermal accumulator obtain maximum heat.Warm-air drier can improve the temperature in the vehicle chamber fast.
The utility model has the advantages that, effectively stored on the motor heat in the cooling medium when travelling, the consumption of fuel and exhaust gas discharging when having reduced cold start-up; Reduced pollution, prolonged the working life of motor environment.Can be widely used in cold area outdoor operation motor car engine, and other engineering, the Transport Machinery of outdoor work.
Fig. 1 is a structural representation of the present utility model, and (1) is motor among the figure; (2) be radiator; (3) be thermorelay; (4) be the distributing T-pipe control valve; (5) be thermal accumulator; (6) be recycle pump; (7) be warm-air drier; A, b are temperature transducer; Arrow is the cooling medium flow direction.
Fig. 2 is the structural representation of thermal accumulator, and (8) are the cooling medium inlet among the figure; (9) be the cooling medium outlet; (10) be thermal insulation layer; (11) be the heat accumulation sheet; (12) be dividing plate; (13) be shell; (14) be the cooling medium heat exchange chamber.
An existing accompanying drawings embodiment of the present utility model.Heat-stored device is that a cooling medium circulation loop of being made up of warm-air drier (7), recycle pump (6), distributing T-pipe control valve (4), thermal accumulator (5) and thermorelay (3) is set on the motor of automobile.During engine operation, by radiator (2) heat radiation, cooling medium flow back into motor (1) by recycle pump (6) through three-way valve (4) and thermal accumulator (5) except that normal.The high temperature cooling medium of process thermal accumulator (5) contacts with heat accumulation sheet (11) and carries out heat exchange, and the heat storage medium solid salt heat absorption in the heat accumulation sheet (11) is melted, and finishes accumulation of heat.Because the effect of the thermal insulation layer (10) of thermal accumulator, when outdoor temperature was-20 ℃, the temperature of cooling medium still can keep about 75 ℃ after 48 hours in the thermal accumulator.During engine start, with the input of the high temperature cooling medium in the thermal accumulator (5) motor (1), improve the temperature of motor, guarantee the normal startup of motor by recycle pump (6).
