Description
Technical Field
The invention belongs to auxiliary equipment for glass coating, and particularly relates to a constant-temperature heating device for coating working gas.
Background
The coating working gas is argon, nitrogen and oxygen. The three gases are indispensable for glass coating, and the quality of the three gases also seriously affects the qualification of the coated glass film layer, so that the control of the states of the three gases is very important. However, in northern climates, winter is cold and summer, the temperature difference between winter and summer can reach more than 40 degrees, and in the practical production process, the fact that even if the parameters of glass of the same film system are completely the same, the uniformity and the transmittance of the glass plated in winter and summer have some differences is found, and more seriously, the glass plated in winter occasionally has small white spots, which seriously influences the quality of products. In continuous groping, the temperature of the working gas is found to be problematic because the high-pressure gas cylinder of the working gas is placed outdoors, the temperature of the gas cylinder is 5-10 ℃ below zero in winter, and the temperature of the gas cylinder reaches 30-40 ℃ in summer. Such a large temperature difference has already seriously affected the film quality of the coated glass.

Detailed Description
In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
The invention provides a constant-temperature heating device for a coating working gas, which is arranged between a coating cavity and a gas cylinder 5 and comprises a heat exchanger 1, a connecting water pipe 2 and a copper thin pipe 3, wherein the heat exchanger 1 is connected with a water outlet pipe 4 of the coating cavity through the connecting water pipe 2, the heat exchanger 1 is arranged below the gas cylinder 5, one end of the copper thin pipe 3 is connected with the heat exchanger 1, the other end of the copper thin pipe is connected with a cooling room through the connecting water pipe 2, and the copper thin pipe 3 is wound on the gas cylinder 5.
The principle of the novel constant-temperature heating device for the coating working gas is that equipment in a coating cavity is cooled by water, and the water which absorbs the equipment in the cavity returns to a cooling room for cooling and then is recycled. Meanwhile, the temperature of water for cooling equipment in the cavity is always kept at about 30 ℃, so that the constant temperature of the water is utilized to keep the temperature of the high-pressure gas cylinders 5 of the three working gases before the water returns to a cooling room, the external temperature is lower than the temperature of the water in winter, the water heats the high-pressure gas cylinders 5, the external temperature is higher than the temperature of the water in summer, and the water cools the high-pressure gas cylinders 5, so that the temperature of the high-pressure gas cylinders 5 is effectively kept at about 30 ℃.
Specifically, will carry to heat exchanger 1 for the water after the equipment cooling in the coating film cavity through connecting water pipe 2, heat exchanger 1 is put in gas cylinder 5 below, heat exchanger 1 directly takes place the heat transfer with gas cylinder 5, later water flows through copper tubule 3, because copper tubule 3 is the winding on gas cylinder 5, consequently hydroenergy carries out even heat transfer to whole gas cylinder 5, water after the heat transfer continues to flow and links to each other with the cooling room through connecting water pipe 2, the water that flows back to the cooling room just can continue to recycle.
The constant temperature heating device with the novel structure has the advantages that the temperature of the gas cylinders 5 of the three working gases is constant at about 30 ℃, the uniformity and the permeation of the film layer of the plated glass are also obviously improved, and white spots do not exist. This substantially improves product quality and yield, and reduces unnecessary waste for the company.
In this embodiment, the heat exchanger 1 is a stainless steel heat exchanger 1, and the stainless steel heat exchanger 1 has high strength and long service life.
