Description

A solar miniature heat dissipation system for a car compartment

technical field

The utility model belongs to the technical field of special ventilation for car compartments or other air treatment equipment.

Background technique

In summer, when the sun is exposed to the sun and the ambient temperature is above 30°C, the air temperature in the car will rise by about 10°C about 15 minutes after the vehicle is turned off, and after two hours of exposure, it will basically reach a peak value of about 60-68°C, and the seat surface temperature will be about 75°C , The surface temperature of the dashboard console is about 85°C or even higher. The indoor thermal environment of the vehicle directly affects the mental state of the drivers and passengers; and there are many plastic products in the interior of the car, which will produce formaldehyde, benzene and other pollutants after long-term exposure to the sun, which will have a negative impact on human health; if you want to open it in advance before entering the car Air-conditioning is time-consuming and fuel-intensive, which is very uneconomical; a comfortable cabin environment can reduce fatigue and make people feel better, thereby improving work efficiency and driving safety. Therefore, how to ensure that the temperature in the car compartment parked outdoors will not be too high and how to improve the comfort of the car is a problem worth exploring.

The main problems existing in the existing solar radiators for vehicles: the existing solar heat dissipation products on the market all use the principle of converting solar radiation energy into electric energy to drive the fan to rotate, and discharge the air inside the car to the outside of the car. The latest product is a set of The solar panel and the fan are integrated into one body, and the shape is small and compact, as long as it is placed on the window of the car. Although this kind of radiator uses a sealing strip to seal the other gaps of the car window except where the radiator is placed, it cannot guarantee the airtightness of the car. When it rains heavily, the sealing strip may completely lose its effect; Too small, the air volume of the fan is not large, and the cooling effect is not significant. Therefore, general solar radiator products cannot effectively solve the problem of high temperature in the compartment.

Contents of the invention

The technical problem solved by the utility model is to provide a solar heat dissipation system for a car compartment, which is used for a stationary vehicle, and supplies power to a micro fan installed in the car through a solar panel, so that the micro fan device can be used without starting the engine. The hot air in the car is drawn out, so that the air in the airtight car can form a convective exchange with the outside world, so as to ensure that the temperature of the car is maintained at a normal temperature suitable for the human body.

The technical scheme adopted by the utility model is: a solar miniature heat dissipation system for a car compartment is composed of a solar panel (1), a fan heat dissipation device (2) and a power cord (3), and the main body of the fan heat dissipation device (2) is A box structure, the air inlet and outlet are located on both sides of the box. A fan box body (4), a battery power supply (5), a temperature sensor and a circuit board (6) are arranged inside it, wherein a motor (9) and a fan (10) are arranged inside the fan box body (4); the battery power supply ( 5) A power socket is provided on the top, connected to the solar panel (1) through a power cord (3), and the solar panel (1) supplies power to the battery (5) to drive the fan (10); the circuit board (6) The car is equipped with a temperature sensor, a shift switch, and an indicator light, among which the indicator light and the shift switch are set on the front of the box body, and a display screen shows the ambient temperature detected by the sensor: if the temperature in the car exceeds the set value, the fan will be activated. (10), and automatically adjust the fan (10) air volume according to the difference between the detected temperature and the set temperature, or manually adjust the air volume, so that the hot air in the car is discharged.

Compared with the prior art, the present invention has the beneficial effects of: using the bracket to place the solar panel as a baffle at the position of the front windshield in the car, on the one hand, it can effectively block sunlight and reduce heat transfer, and at the same time, it can maximize Use solar energy to convert it into electrical energy; use exhaust fan, double-sided air intake, large and rapid air volume, oblique air inlet minimizes the friction between wind and air duct, while reducing noise, it can increase the natural speed of the fan . The fan is arranged in the external ventilation system of the car, and the hot air in the car is sent out of the car through the air-conditioning duct, so that the car does not need to open the window or start the engine, and the cabin temperature is still maintained at a normal temperature suitable for the human body.
