Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to a multi-stage cooling modular glass substrate rapid cooling device. Background Art

[0002] A glass substrate is a thin sheet of glass with an extremely flat surface. There are three production methods: float glass, overflow downdraw, and slit downdraw. Immediately after production, the substrate glass undergoes cooling to improve its physical properties before undergoing a series of processing steps. Glass substrates are essential components of liquid crystal display devices. During production and processing, temperature control equipment is required to precisely control the ambient temperature to ensure high quality. Rapid cooling devices are also required to achieve this.

[0003] Existing cooling devices can only cool down a single side of the glass substrate at a time, resulting in uneven cooling of the glass substrate, which can easily cause deformation of the glass substrate and further affect the quality of the finished glass substrate. Utility Model Content

[0009] As a further improvement of the present technical solution, an air inlet is provided on one side of the fan, and a filter is provided inside the air inlet of the fan.

[0010] As a further improvement of the present technical solution, multiple first air injection tubes are arranged above the installation frame, multiple second air injection tubes are arranged below the installation frame, and air injection holes are opened on opposite sides of the multiple first air injection tubes and the second air injection tubes.

[0011] Compared with the prior art, the present invention has the following beneficial effects:
