Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum furnace cooling, in particular to a high-temperature furnace cooling water channel structure. Background Art

[0002] The working principle of the vacuum furnace is: the gas in the furnace cavity is discharged by the vacuum system so that the pressure in the furnace is less than a standard atmospheric pressure, thereby realizing the process flow under a certain vacuum state. In order to achieve this process flow, the vacuum furnace needs to be cooled and cooled down at the same time as the high-temperature heating. In the existing high-temperature furnace, the cooling system adopts the form of one water inlet and two water returns, both of which are independent structures; but for large-scale high-temperature vacuum furnaces, the independent cooling water system has the following problems: (1) The independent cooling water system is difficult to disassemble and reinstall, which is very time-consuming. (2) The independent cooling water system is generally around the furnace body and occupies a large area. (3) The independent cooling water system needs to be disassembled and packaged separately for transportation, which not only increases the risk of damage during transportation, but also increases the packaging labor and transportation costs.
