Detailed description of the invention
With detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.
The structure of the single crystal growing furnace cooling alarm device that this utility model provides as depicted in figs. 1 and 2, is used for monitoring single crystal growing furnace
Cooling piece 1 in the state of cooling medium.Cooling medium flows in or out cooling piece 1 via cooling pipe 2.Single crystal growing furnace cooling report
Alarm device includes pressure gauge 3, effusion meter 4, controls box 5 and alarm 6.
Pressure gauge 3 is installed on cooling pipe 2, and signal is connected to control box 5.In the present embodiment, pressure gauge 3 is electric contact
Pressure gauge, the normal pressure scope that sets of electric contact pressure gauge is as P1＜ P ＜ P2.Specifically, P1With P2Value can be according to cooling
The practical situation such as position that part 1 needs the cooling effect that reaches, pressure gauge 3 to be installed on cooling pipe 2 is configured.
Effusion meter 4 is installed on cooling pipe 2, and signal is connected to control box 5.In the present embodiment, effusion meter 4 leaves for flow
Closing, the normal discharge scope that sets of flow switch is as Q1＜ Q ＜ Q2.Specifically, Q1With Q2Value can be according to cooling piece 1 needs
The practical situations such as the cooling effect that reaches, pressure gauge 3 position being installed on cooling pipe 2 are configured.
