Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to a cooling device for a glass tempering furnace. Background Art

[0002] During the operation of a glass tempering furnace, ordinary flat glass needs to be heated to form compressive stress on the surface of the cooled glass and tensile stress inside the glass, thereby increasing the strength of the glass and turning ordinary annealed glass into tempered glass. Since the tempering furnace has a heating step in the tempering process of the glass, the tempering furnace needs to be cooled. The existing cooling device of the glass tempering furnace generally uses a fan to dissipate the temperature. However, the effect of using only a fan to transfer internal heat is not ideal, and the cooling efficiency is also low.

[0003] In order to solve the above problems, application number CN202022307212.8 discloses a glass tempering furnace cooling device, in which cooling water is introduced into the water trough through a water inlet pipe, and the cooling water flows into the cooling trough through the water trough. The good heat collection performance of the heat-conducting aluminum plate is utilized to transfer the heat in the box to the heat-conducting copper tube, and the heat-conducting copper tube is cooled by the cooling water, thereby achieving a good heat conversion process to reduce the internal temperature of the box. With the assistance of the cooling fan, the excess heat in the box is discharged, forming a good heat dissipation and cooling process, further improving the cooling efficiency; the cooling water is facilitated to flow to the water outlet for recovery through the drainage block, and the heat-conducting copper tube is inclined to promote the flow of cooling water and prevent it from being retained in the box; a water distribution plate is provided to facilitate the cooling water to spread and flow in the water trough, achieving a more uniform cooling effect; ventilation holes are provided to maintain the air pressure stability in the box, a dust net is provided to prevent excessive dust from falling into the box, and a moisture-absorbing sponge is provided to collect the water vapor generated inside the box.

[0004] The cooling device for the glass tempering furnace disclosed in the above patent absorbs heat by injecting flowing cold water into the interlayer of the furnace shell. However, due to the metal furnace shell, the cooling effect is poor. Utility Model Content

[0005] The purpose of the utility model is to provide a cooling device for a glass tempering furnace. The cooling device for a glass tempering furnace disclosed in the utility model cools the glass tempering furnace by means of a cooling assembly consisting of a top water trough, a top water distribution ring trough, a water diversion chain and a bottom water connection ring trough. Water is pumped from a water tank into the top water trough. When the cold water flows downward along a number of water diversion chains, the water evaporates and absorbs heat on the inner wall of the furnace shell. The cooling effect is good when combined with a fan and the cold water can be recycled, thereby solving the problems raised in the above-mentioned background technology.
