Abstract

The invention provides a self-energy-driven portable type parking ventilation and cooling system, and belongs to the technical field of automobile ventilation. The self-energy-driven portable parking ventilation and cooling system comprises a solar cell panel, a storage battery, a measurement and control element and a ventilation device, wherein the solar cell panel is arranged in a cab platform in a vehicle; the measurement and control element detects the temperature in the vehicle and detects whether passengers are in the vehicle or not and controls the ventilation device; the ventilation device comprises a fan and an air exhaust device shaped like a Chinese character 'jie', and the ventilation device is installed on a vehicle window; and the storage battery is charged through the solar cell panel, and power is supplied to the measurement and control element and the ventilation device. According to the self-energy-driven portable type parking ventilation and cooling system, the vehicle is not modified, a circuit is not added, installation is convenient, and install-and-use effect can be realized; batch production is easy to realize, and raw materials are low in cost and green and environment-friendly; the design of a temperature field and an organizing flow field in the vehicle can be scientifically utilized, so that the cooling effect is obvious; and the safety performance, the anti-theft performance and the like of the device can be ensured.

Description

technical field [0001] The invention relates to the technical field of automobile ventilation, in particular to a self-energy-driven portable parking ventilation and cooling system. Background technique [0002] The strong solar radiation in summer, the heat conduction of the car body and the greenhouse effect of the car make the interior temperature of the car rise rapidly. This phenomenon of parking high temperature firstly leads to the load of the air-conditioning system when starting the car; secondly, it leads to the aging of the car body materials and the volatilization of toxic substances at high temperatures, which not only seriously deviates from the passenger's demand for thermal comfort, but also affects Their health; if there are children and elderly people left in the car, it may cause tragedy. [0003] In response to this problem, the currently disclosed technology is mentioned in the "Summary of the Application of Solar Parking Ventilation Technology" in the ...
