Description

Technical Field

[0001] The utility model relates to the technical field of automobile heat dissipation, in particular to a structure for accelerating the flow of air inside a vehicle and a vehicle. Background Art

[0002] As users' requirements for automobile comfort, appearance, lighting, etc. increase, more and more OEMs prefer skylight glass and low-slung designs. While providing users with a high-end experience, OEMs also bring new troubles to users. For example, the temperature inside the car is high in summer, especially in the skylight glass area. Hot air gathers in the upper space of the car, and the air circulation above the head is poor. The human head is extremely sensitive to temperature, and overheating of the head has become one of the main complaints of users.

[0003] Based on the above problems, OEMs currently generally use the following methods to indirectly reduce customer complaints. The first method is to add a medium between the skylight glass and the user's head to block external heat. For example, patent document CN219505585U discloses an adjustable heat-insulating film for skylight glass. This method is limited by cost and space layout, and is contrary to the original intention of developing skylight glass. Customers' lighting quality is directly reduced. The second method is to use skylight glass with good physical properties. For example, patent document CN220146870U discloses a high-insulation, noise-reducing, radiation-proof vacuum glass and its manufacturing method, but the manufacturing and maintenance costs of this type of glass are high, and the cost performance is low. The third way is to improve the heat accumulation in the user's head area by accelerating the air flow in the head area, such as the vehicle skylight glass temperature control method disclosed in patent document CN116373537A, in which the temperature regulating device includes a skylight air outlet arranged on the ceiling and facing the skylight glass, and the temperature regulating device and the skylight air outlet are controlled to open and close by obtaining the glass temperature of the skylight glass and the light intensity of the light irradiating the skylight glass to control the temperature of the skylight glass; however, this method does not explain the specific structural layout of the heat exchanger, and needs to add a device similar to an air conditioner in the car, which will be limited by the space layout and increase the cost.

[0004] In summary, the existing cooling air outlet designs cannot solve the problem of "perming hair" in summer for users of vehicles with small headroom in an economical and environmentally friendly way. Therefore, it is necessary to develop a new structure for accelerating the air flow in the vehicle and a vehicle. Summary of the invention
