Description
Technical field
The present invention relates to a kind of instrument board cooling system, particularly a kind ofly utilize light to heat to come improving heat radiation efficiencyInstrument board cooling system.
Background technology
In general,, in the local time that storing cycle is unsheltered out of doors, now vehicle can be subject to strong the tanning by the sun of the sunAnd make the rapid rising of vehicle interior temperature, and the state in sealing normally during due to storing cycle, vehicle is held as baking boxTemperature of continuing rising and be difficult for heat radiation, causes electronic installation in car because having reduced electronic installation in the long-time environment in high temperatureIn service life, even make electronic installation damage because of overheated. On the other hand, in the time of vehicle startup, user can hold cold air conventionallyRegulate the temperature in car, but vehicle still can make because being subject to tanning by the sun of the sun temperature rise, relative increase coldThe consumption of gas.
Overheated and cause electronic installation impaired for fear of instrument board, in existing technology, can be divided into four kinds of strick precautions rightPlan, is first aspect radiant heat, normally utilizes sheathing paper or car cover to reduce tanning by the sun of the sun; And aspect thermal convection current,Be mainly to utilize the mode of solar energy to carry out flowing of the interior air of drive fan band motor-car, and then assist instrument board heat radiation; Exist in additionHot conduction aspect can utilize heat pipe to assist instrument board heat radiation; Finally aspect phase change, the form that can spray, profitThe evaporation latent heat of water absorbs the heat in car, and steam is derived outside car.
From the above, avoiding in the overheated technology of instrument board, existing technology not only effect is limited, and cost is high,And cannot popularize in general masses. Edge this, this case inventor thinks real a kind of new instrument board cooling system that is necessary to develop,Make it can utilize the sun to tan by the sun produced heat with the flowing of moving air flow, and then increase the radiating efficiency of instrument board, and notNeed additional power, effectively reduce cost.
Summary of the invention
The defect and the deficiency that exist for prior art, main purpose of the present invention is to provide a kind of instrument board heat radiation to beSystem, its heat transmitting can utilize the sun to tan by the sun time drives the convection current of instrument board internal gas flow, uses effective increaseRate of heat dispation, and can effectively reduce cost.
For achieving the above object, the present invention by the following technical solutions: a kind of instrument board cooling system, it is applied in an electricityThe heat radiation of sub-device, and electronic installation is installed in a vehicle, and instrument board cooling system comprises an instrument board and transparentWindow. Instrument board offers an air intake vent, a ventilating duct and an air outlet, and air intake vent is positioned at the bottom of instrument board, and air outlet is positioned atThe top of instrument board, and ventilating duct is between air intake vent and air outlet, and the contiguous air outlet of ventilating duct place is gradually-reducing shape; ItsIn, above-mentioned electronic installation is arranged on instrument board. Transparency window is arranged at the top of instrument board, and transparency window also perceives ventilationThe part in road, uses and makes light expose to ventilating duct via transparency window. Wherein, ventilating duct receives outside light by transparency windowLine, and make the temperature rise of ventilating duct, and then drive the air in instrument board to be flowed to air outlet by air intake vent, use electronicsDevice dispels the heat.
In a preferred embodiment of the present invention, ventilating duct also has a black endothermic section, in order to absorb outside light.Preferably, black endothermic section is arranged at transparency window below accordingly.
In a preferred embodiment of the present invention, instrument board also offers a discharge outlet, and it is arranged at air outlet below.
In a preferred embodiment of the present invention, instrument board cooling system also comprises a miniature natural ventilator, its settingOn air outlet.
In a preferred embodiment of the present invention, instrument board cooling system also comprises a fan, and fan is arranged at air outletUpper, use the cross-ventilation speed making in instrument board and promote. Preferably, instrument board cooling system also comprises a solar cell,Solar cell is arranged on a roof of vehicle, and solar cell is electrically connected at fan.
In a preferred embodiment of the present invention, air outlet be exposed to a front windshield of vehicle and a bonnet itBetween.
In a preferred embodiment of the present invention, air intake vent is exposed to a chassis place of vehicle.
In a preferred embodiment of the present invention, electronic installation is removable installed on instrument board, and electronic installation isOne external hanging type panel.
The present invention contrasts effect of prior art:
From with above-mentioned, compared to cooling method in the car described in prior art, due at instrument provided by the present inventionIn dash board cooling system, be the principle of utilizing stack effect, the used heat that solar radiation is produced is used for driving instrument board insideAir Flow, and then electronic installation is dispelled the heat, compared to the cooling method of prior art, the present invention really can be effectiveIncrease the rate of heat dispation of electronic installation, and arrange with low cost, more do not need to expend other energy and drive running, only utilize tooThe radiation of sun can be reached.
In addition, the Bai Nuli law that the present invention is more inversely proportional to by pressure and flow velocity, in the time that vehicle is advanced, because of outside vehicleWind speed very fast and make outside air pressure little with respect to the air pressure of instrument board inside, make the air of instrument board inside can be from air-outMouth accelerates to flow out, and effectively helps electronic installation heat radiation.
