Abstract
The utility model relates to a device for ventilation and refrigeration for parking cars by using solar energy, which relates to ventilation and refrigeration techniques. A solar cell is arranged at a position which can receive sunshine on a body of a car, and the solar cell is mutually connected with an exhaust fan and/or a refrigerating device through a conducting wire. A switch is arranged on the conducting wire among the solar cell and the exhaust fan and/or the refrigerating device, and the exhaust fan and/or the refrigerating device is arranged on the body of a car. The utility model uses energy produced by the solar cell to drive the exhaust fan and/or the refrigerating device, when the car stops under the sunshine of the blazing sun, power produced by the solar cell can be used for conducting the ventilation, heat removal and refrigeration for the inner part of the car. When an owner of a car reenters the car, the temperature in the car is comfortable relatively and no loss can be produced to the cell life of the car.
Description
Technical field
This practicality newly relates to the ventilation Refrigeration Technique, ventilates, dispels the heat in specifically a kind of car that utilizes solar power to give to have stopped/device that freezes.
Background technology
When automobile is parked in the following long period of sunlight, it is awfully hot that car inside can become.So in the time of in the car owner reenters car, often think that high heat unbearably.Continue to open exhaust fan or cooling blower after if engine stopped, battery will exhaust very soon.
Summary of the invention
The purpose of this utility model is to design a kind of device of giving parking ventilation refrigeration with solar power, the energy that utilizes solar cell to produce promotes exhaust fan and/or refrigeration device, make automobile be parked in the following time of sunlight of burning sun, the power that can utilize solar cell to produce, to automotive interior ventilate, heat extraction, refrigeration.In the time of in the car owner reenters car, vehicle interior temperature is pleasant comparatively speaking, and the battery life of car itself is not had any loss.
According to design plan provided by the utility model, the position that can accept sunlight on auto body is provided with solar cell, solar cell and exhaust fan and/or refrigeration device utilize lead to interconnect, and on the lead between solar cell and exhaust fan and/or refrigeration device, switch being set, exhaust fan and/or refrigeration device are installed on the vehicle body.
Solar cell is positioned at vehicle dormer window or/and the inboard of glass for vehicle window or the outside.Solar cell is installed on the sun shield in automotive window or skylight, and is positioned on the outside face of sun shield.On the lead between solar cell and exhaust fan and/or refrigeration device, temperature responsive switch is set.
Usually the vehicle dormer window size is about 35cm * 80cm, is about 2800cm
2If on the interior window sun shield of vehicle dormer window, settle solar cell, perhaps in skylight glass, settle solar cell, with at present in the world preferably 20% photoelectric transformation efficiency calculate, can produce and surpass 50 watts electric power.So power enough drives exhaust fan or/and air conditioning for automobiles.Make automobile keep inner ventilation refrigeration under dead ship condition, Wen Buhui is too high in making.The car owner can be too not hot when reentering in the car.And new-type two sun-roof automobile can be with the sky window ara, just abovely can get solar-electricity power and is enhanced about more than once.
Description of drawings
Figure 1A is a kind of mounting means of the present utility model.
Figure 1B is an another kind of mounting means of the present utility model.
Fig. 2 is control circuit figure
The specific embodiment
As shown in the figure: the position that can accept sunlight on auto body 2 is provided with solar cell 3, solar cell and exhaust fan 7 and/or refrigeration device 8 utilize lead to interconnect, and on the lead of 8 of solar cell 3 and exhaust fan 7 and/or refrigeration devices, switch 5 being set, exhaust fan 7 and/or refrigeration device 8 are installed on the vehicle body 2.
Figure 1A is installed on the sun shield 4 in automotive window or skylight 1 for solar cell 3, and is positioned at the scheme drawing on the outside face of sun shield 4.When stopping, sun shield 4 to be pulled out, solar cell 1 exposes in the sun fully.The method does not have new requirement to skylight 1 and solar cell 3, implements simpler.This method is also economical a lot of on the skylight glass plate with solar cell 3 devices than following simultaneously.
The scheme drawing of Figure 1B when solar cell 3 being placed below the glass in skylight 1 when this scheme of use, requires solar cell 3 thinner, so that most of light can see through, and skylight 1 is still more transparent.Note simultaneously also it to be installed on automobile side-window and the rear window when solar cell 3 is more transparent, increase effective daylighting area, raising can utilize solar-electricity power.
On the lead of 8 of solar cell 3 and exhaust fan 7 and/or refrigeration devices, temperature responsive switch 6 is set.As shown in Figure 2, after automobile key took off, gang switch 5 was the circuit UNICOM between solar cell 3 and exhaust fan 7 or the A/C 8, exhaust fan 7 and A/C 8 or the refrigeration of air discharging and radiating at the beginning of the two.Make vehicle interior temperature be unlikely to too high.
When vehicle interior temperature was lower than uniform temperature, temperature responsive switch 6 can be cut off air draft/refrigeration circuit automatically, to prolong the life-span of solar cell 3.
In control circuit, also can add the simple logic system, with control exhaust air rate and air-conditioning power.So regulate the load and the requirement of air discharging and radiating refrigeration of solar cell 3 most effectively.
It should be noted that when the efficient of solar cell 3 is low the power that produces on 1 area of skylight may be not enough to promote simultaneously exhaust fan 7 and air conditioner 8 simultaneously with maximum power operation, at this moment only with both one of or both simultaneously low power turn round.Even so still heat extraction reduces vehicle interior temperature in a large number.When high performance solar batteries 3 occurs in the future, the solar cell 3 with day window ara will produce enough power, can promote the operation of exhaust fan 7 and air conditioner 8 full powers simultaneously.
In addition, this method also can be applicable in other similar air discharging and radiating refrigeration application, for example house window formula air discharging and radiating refrigeration etc.Among Fig. 29 is automobile storage battery.
