Abstract
The invention discloses an instrument panel cooling system. The system comprises an instrument panel and a transparent window. An electronic device is disposed on the instrument panel, which is further provided with an air inlet, a ventilation duct and an air outlet. The air inlet is arranged at the bottom end of the instrument panel and is used to introduce air into the interior of the instrument panel. The air outlet is arranged at the top end of the instrument panel. The ventilation duct is located between the air inlet and the air outlet, and a part of the ventilation duct close to the air outlet shrinks gradually. The transparent window is arranged on the top end of the instrument panel so that light can pass through the transparent window and irradiate the ventilation duct. The ventilation duct receives external light through the transparent window, so that the temperature rises and air inside the instrument panel is driven to flow through the electronic device towards the air outlet to cool the electronic device.
Description
Technical field
The present invention relates to a kind of instrument board cooling system, particularly a kind of instrument board cooling system that utilizes light to heat to come improving heat radiation efficiency.
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 and make the rapid rising of vehicle interior temperature of the sun, and during due to storing cycle normally in sealing state, make vehicle just as persistently overheating and difficult heat radiation as baking box, cause electronic installation in car useful life because having reduced electronic installation in the long-time environment in high temperature, even make electronic installation damage because of overheated.On the other hand, in the time of vehicle startup, conventionally user can drive cold air and regulate the temperature in car, but vehicle still can make because being subject to tanning by the sun of the sun temperature rise, relative increase the consumption of cold air.
Overheated and cause electronic installation impaired for fear of instrument board, in existing technology, can be divided into four kinds of prevention methods, be first aspect radiant heat, normally utilize sheathing paper or car cover to reduce tanning by the sun of the sun; And aspect thermal convection, 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; Aspect heat conduction, can utilize heat pipe to assist instrument board heat radiation in addition; Finally aspect phase change, the form that can spray, utilizes evaporation of water latent heat to absorb 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 and is necessary to develop a kind of new instrument board cooling system, makes it can utilize the sun to tan by the sun produced heat with the flowing of moving air flow, and then increases the radiating efficiency of instrument board, and do not need additional power, effectively reduces 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 cooling system, 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 increase rate 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 the heat radiation of an electronic installation, and electronic installation is installed in a vehicle, and instrument board cooling system comprises an instrument board and a transparency window.Instrument board offers an air intake vent, an air duct and an air outlet, and air intake vent is positioned at the bottom of instrument board, and air outlet is positioned at the top of instrument board, and air duct is between air intake vent and air outlet, and the contiguous air outlet of air duct place is gradually-reducing shape; Wherein, above-mentioned electronic installation is arranged on instrument board.Transparency window is arranged at the top of instrument board, and transparency window also perceives the part of air duct, uses and makes light expose to air duct via transparency window.Wherein, air duct receives outside light by transparency window, and makes the temperature rise of air duct, and then drives the air in instrument board to be flowed to air outlet by air intake vent, uses electronic installation is dispelled the heat.
In a preferred embodiment of the present invention, air 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, and it is arranged on air outlet.
In a preferred embodiment of the present invention, instrument board cooling system also comprises a fan, and fan is arranged on air outlet, uses the cross-ventilation speed making in instrument board and promotes.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 is exposed between a front windshield and a bonnet of vehicle.
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 is an 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 in instrument board cooling system provided by the present invention, it is the principle of utilizing stack effect, the used heat that solar radiation is produced is used for driving the Air Flow of instrument board inside, and then electronic installation is dispelled the heat, compared to the cooling method of prior art, the present invention can effectively increase the rate of heat dispation of electronic installation really, and what arrange is with low cost, more do not need to expend other energy and drive running, only utilize the radiation of the sun to reach.
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 the wind speed of outside vehicle comparatively fast makes outside air pressure little with respect to the air pressure of instrument board inside, make the air of instrument board inside accelerate to flow out from air outlet, effectively help electronic installation heat radiation.
Specific embodiment of the present invention, by the embodiment by following and graphic being further described.
