Automobile phase-change sun protection film

Abstract

The invention discloses an automobile phase-change sun protection film. The automobile phase-change sun protection film comprises a sun protection film and a winding rod connected with the sun protection film; bases connected with a roof are arranged on the two sides of the winding rod; driving devices are arranged on the bases; the driving devices are connected with the sun protection film; the sun protection film comprises a light shielding heat collecting layer on the external side and a heat absorbing layer on the internal side; a phase change layer is arranged between the heat absorbing layer and the light shielding heat collecting layer; the phase change layer comprises a phase change material and a film coating on the phase change material; the light shielding heat collecting layercomprises a transparent film and a light collecting film; a shutter blind and a supporting pad are arranged between the light collecting film and the transparent film; and the supporting pad is positioned around the shutter blind. The automobile phase-change sun protection film disclosed by the invention has the advantages that the structure is simple, the use is convenient, heat insulation and sun protection can be effectively realized, and by using the phase change material, heat in an automobile is absorbed during phase changing so that the temperature in the automobile is reduced.

Description

technical field [0001] The invention relates to the field of cooling, in particular to a phase-change sunscreen film for automobiles. Background technique [0002] With the development of science and technology and the continuous growth of the national economy, cars are now common in every family. Due to urban planning and tight parking, most vehicles are parked in the open. The high temperature weather in summer makes the car parked in the open air easy to absorb heat and difficult to release heat, so the temperature inside the car is much higher than the ambient temperature, which poses a great hidden danger to the safety of the car. However, due to the fact that the parked cars do not have an effective temperature regulation system that can work, it cannot effectively solve the problem of excessive temperature in the car. Therefore, when the car is parked for a long time in summer, it is generally necessary to cool the interior of the car through the air conditioner to ...

AI Technical Summary

Problems solved by technology

The high temperature in summer makes the car parked in the open air, because it is easy to absorb heat and difficult to release heat, so the temperature inside the car is much higher than the ambient temperature, which poses a great hidden danger to the safety of the car

However, due to the fact that the cars parked under normal circumstances do not have an effective temperature regulation system that can work, the problem of excessive temperature inside the car cannot be effectively solved.

Therefore, when the car is parked for a long time in summer, it is generally necessary to cool the interior of the car through the air conditioner to reduce the temperature inside the car quickly. This will not only greatly increase the energy consumption of the car, but also cause toxic gases to more harmful to the human body
