[detailed description of the invention]
Below in conjunction with accompanying drawing, to being originally described further, the structure of this device and principle are very clearly concerning this professional people.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of temperature-adjusting device in the utility model city, comprise housing, solar panel, battery pack, circuit controller and phase-change material container, case top is provided with solar panel, housing periphery is provided with air inlet and air outlet, in housing, be provided with phase-change material container, phase-change material container is closed container, in phase-change material container, establish ventilation shaft, ventilation shaft outside is provided with phase-change material and is full of phase-change material container, air inlet and air outlet place are respectively equipped with fan, realize heat exchange by forced-convection heat transfer in pipeline.
Solar panel connects controller by electric wire, and controller connects battery pack by electric wire, and battery pack connects fan governor by electric wire, and fan governor connects the fan at air inlet and air outlet place by holding wire; Ventilation shaft in phase-change material container is snakelike reciprocal arrangement, described phase-change material adopts the phase-change material of specific latent heat value >=150KJ/Kg, phase-change material is the inorganic chemical combination phase-change materials such as crystalline hydrate salt, fuse salt, phase change paraffin or fatty acid and polyethylene glycol system; Phase-change material is arranged in phase-change material container by microcapsules or coated processing, and phase-change material container adopts the non-closed container of metal grill; In controller, be provided with electric weight sensor, timer, receiver of remote-control sytem, mobile radio network sensing receiver or whistle control system.
Solar panel is accumulative total generating under the daily solar radiation of vehicle, is filled with in the battery pack of over-charge protective, to supply whole device running by voltage stabilization and current stabilization circuit controller.
This device is applicable to being placed on the dividing plate platform of vehicle front and rear windshield below, leaves vehicle driver, after air-conditioning is closed, under the environment that causes vehicle interior temperature to rise because of reasons such as sunshines, plays a role.In normal vehicle operation and stop, ventilation equipment operate with lower-wattage, increase Air Flow in car, improve passenger inside the vehicle's comfort level; When vehicle interior temperature raise and start higher than phase-change material set phase transition temperature (phase transition temperature is set to conventionally higher than air conditioner refrigerating temperature) time, temperature sensor conducted signal increases ventilation equipment power, electric energy is converted into aerodynamic energy by ventilation equipment, makes air in car be blown into through internal tank, becomes snakelike reciprocal arrangement, wrapped up completely by phase-change material and it is moulded between pipe outer wall and inner surface of container the ventilation heat pipe that homogeneous quality distributes; Air has longer time and larger surface area that Surface Contact occurs with it while flowing in ventilation heat pipe, flow and contact with the surface of ventilation heat pipe by air, air is higher than the part sensible heat of phase-change material phase transition temperature, by by ventilation heat pipe Direct Uniform conduct to the phase-change material in container; Airborne a part of sensible heat is absorbed as after latent heat of phase change by phase-change material, just gets back in car to be slightly higher than the temperature of phase transition temperature lower than original temperature, moves in circles, and can reduce air themperature or slow down air rate of rise in temperature; Due to the characteristic of phase-change material, this heat exchange will last till that unit phase-change material absorption is not less than the heat energy of its latent heat of phase change and becomes liquid phase completely from solid phase.
If phase transformation finishes the air themperature of rear automotive interior still higher than phase-change material, because ventilation equipment work on, the heat exchange of phase-change material and Che Nei air is conducted into phase-change material sensible heat by the process that is latent heat of phase change from the conduction of air sensible heat to air sensible heat and changes; Because the specific heat capacity of phase-change material is greater than the specific heat capacity of air, so the heat conduction between both sensible heats still can reduce the speed that air themperature or the air themperature that slows down rise; When air conditioning for automobiles reopens, or at nightfall vehicle interior temperature reduces, and in car, air, by ventilation heat pipe and phase-change material, reverse hot conduction occurs, and phase-change material sensible heat is conducted into air sensible heat and reduces the temperature of phase-change material.
When the temperature of phase-change material is reduced to when extremely approaching phase transition temperature, phase-change material just will start reverse transformation, now the latent heat of phase change of phase-change material is discharged into and in air, is become sensible heat by ventilation heat pipe, the speed of transferring to improve air themperature or slowing down mercury dropped, until phase-change material has discharged enough heat energy and has become solid phase completely again from liquid phase.
After phase transformation finishes, the temperature of phase-change material starts lower than phase transition temperature, and temperature-sensitive conduction device sends this signal to controller, and controller reduces the power of ventilation equipment automatically, reduces battery pack power consumption; If now the air themperature of automotive interior is still lower than phase transition temperature, the heat exchange of phase-change material and Che Nei air will be that air sensible heat is that air sensible heat changes to conducting from phase-change material sensible heat from latent heat of phase change conduction.
Second day identical situation gone round and begun again to realize for a long time and recycled.
