Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
Embodiment one:
Consult Fig. 1, in the present embodiment, this automobile-used cooling structure comprises the instrument desk be arranged on below windshield, the hollow member 100 that the surface of described instrument desk is made up of a transparent insulate material is formed, described hollow member 100 is provided with the liquid crystal ink layer 200 of heat colour killing type on the inwall of the side of described instrument desk, liquid crystal ink layer 200 colour killing after reaching design discoloring temperature of described heat colour killing type becomes transparent, described hollow member 100 is just provided with optical reflecting layer 120 between the inwall of described instrument desk side and described liquid crystal ink layer 200, described hollow member 100 is provided with infrared reflection coating 110 back to a side surface of described instrument desk.
The colouration mechanism of liquid crystal ink: liquid crystal entirety forms helical structure, when light is incident from the helical axis directions being parallel to planar alignment, is just divided into left-handed rotation and right-handed rotation two kinds of circularly polarized lights.Wherein a kind of light of composition is transmitted, and the light of another kind of composition is then reflected entirely.This phenomenon is called circular-dichroism.In the wavelength region of cholesteric crystal selective light scatter band both sides, there is very strong rotatory, and different in the DL-direction of light scattering frequency band.Because the pitch of most of cholesteric crystal has very strong dependence to temperature, so as long as temperature slightly changes, the wavelength (color) of selective scattering light will change a lot.Generally, the coloring mechanism of liquid crystal is exactly: utilize it to be formed special wavelength light selective reflecting.Liquid crystal ink make use of this characteristic of liquid crystal just, and make liquid crystal under the impact of weak current and temperature, lattice changes and demonstrates LO-pattern and color, and the temperature of reaction of liquid crystal is-100 ~ 700 DEG C.Thermosensitive liquid crystal ink has colour developing, colour killing, variable color three kinds.
Described infrared reflection coating 110, after described hollow member 100 can be made when temperature is high, reflects the infrared thermal radiation that it is launched.
Be provided with radiating component in described hollow member 100, described radiating component is controlled by a temperature control module, and described temperature control module starts described radiating component after car engine.
Described radiating component comprises and is arranged on inlet channel 310 in described hollow member 100 and water outlet 320, and described inlet channel 310 is connected the water-cooling circulating system of automobile with water outlet 320.
Described radiating component directly uses the water-cooling circulating system of automobile, can reduce manufacturing cost, and meanwhile, described water-cooling circulating system only just runs after automobile starting, can replace the function of described temperature control module.
Above-mentioned automobile-used cooling structure, described temperature control module comprises one and is arranged on temperature sensor in described hollow member 100, under automobile is in and does not start state or car locking state, after described temperature control module detects that in described hollow member, temperature reaches warning temperature, the setting of described warning temperature, adopt the principle lower than material the upper limit temperature of heat tolerance to arrange, start described radiating component, make the temperature in described hollow member between described warning temperature and described design discoloring temperature.
Due in the present embodiment, employ water-cooling circulating system as described radiating component, therefore, under automobile is in and does not start state or car locking state, an electronic pump housing 330 should be adopted to drive water-cooling circulating system slowly, make, in described hollow member 100, overheated situation to occur, simultaneously, due in the described water-cooling circulating system of automobile, there is the such thermal source of hollow member 100, after automobile starting, the automobile that temperature in its water-cooling circulating system is more general is high, therefore, after cold-starting automobile, the temperature of driving engine reaches best combustion temperature sooner, make automobile more fuel-economizing.
In the present embodiment, the policy setting (in the water-cooling circulating system of automobile, the temperature constant of refrigerant fluid is 90 degree) be set as higher than cooling-liquid temperature in water-cooling circulating system of design discoloring temperature, namely higher than 90 degree.
Above-mentioned automobile-used cooling structure, described hollow member 100 just to described instrument desk one side wall surface and described hollow member 100 back to described instrument desk a side wall surface between distance be 2mm.
Under the distance reducing described hollow member 100 two sides can make automobile be in not start state or car locking state, by liquid crystal ink layer described in illumination 200, temperature in hollow member 100 described in Fast Heating, make the colour killing fast of described liquid crystal ink layer 200, play the effect of described optical reflecting layer 120, make the light-absorbing energy of instrument desk drop to minimum.
Above-mentioned automobile-used cooling structure, automobile is provided with solar panel, and described solar panel drives described radiating component, and the setting of solar panel can make automobile not starting, under state, not use the electricity of storage battery, effectively prevents storage battery power shortage.
Embodiment two:
Consult Fig. 2 and Fig. 3, in the present embodiment, only the described inlet channel 310 in embodiment one and water outlet 320 being disposed on the wall of described hollow member 100 just to described instrument desk side uniformly, the temperature of described hollow member 100 when dispelling the heat can being made to be consistent evenly.
In sum, fundamental mode of the present invention:
During the broiling summer, after the car locking that kills engine, the described water-cooling circulating system of automobile shuts down, temperature now in water-cooling circulating system is 90 degree, liquid crystal ink layer true qualities in described hollow member 100 are black, liquid crystal ink layer described in solar radiation, by described hollow member 100 inside heating, temperature raises rear described liquid crystal ink layer colour killing gradually, optical reflecting layer 120 in incident described hollow member 100, instrument desk is made to have light reflection ability, reduce the heat absorption of instrument desk, and then reduce the gathering of automotive interior heat, when after car engine, water-cooling circulating system works, temperature return to 90 in described hollow member 100 is spent, described liquid crystal ink layer colour developing, instrument desk is reflected light rays no longer, do not affect driving, the setting of described temperature sensor simultaneously can make the temperature in described hollow member 100 be no more than warning temperature.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
