[0002] In the production of substrate glass, the platinum channel needs to be heated by a direct heating circuit.

[0028] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0029] This embodiment provides a device for cooling a heating flange of a platinum channel of a liquid crystal substrate glass, comprising a cooling water pipe 1, a flange 5, a reinforcing rib 7, a return water thermometer 3 and a water inlet flow valve 4; the cooling water pipe 1 is composed of a cooling coil 2 and a cooling straight pipe 8.

[0030] The cooling water pipe 1 is hollow inside and is welded to the outer edge of the flange 5. One end of the cooling water pipe 1 is connected to the water inlet, and the other end is connected to the water return port. The cooling water pipe 1 cools the flange 5 through cooling water. The cooling water pipe 1 is also welded to the surface of the flange 5, which can effectively increase the cooling area to cool the flange 5.

[0031] Specifically, the cooling coil 2 is arranged on the outer edge and surface of the flange 5, and the two ends of the cooling coil 2 are respectively connected to different cooling straight pipes 8, and the different cooling straight pipes 8 are connected through the cooling coil 2, one cooling straight pipe 8 is connected to the water inlet, and the other cooling straight pipe 8 is connected to the water return port, and a reinforcing rib 7 is provided on the contact surface between the cooling water pipe 1 and the flange 5;

[0032] Specifically, the cooling coil 2 includes a first cooling coil and a second cooling coil, the first cooling coil is arranged on the outer edge of the flange 5, the second cooling coil is arranged on the surface of the flange 5, one end of the first cooling coil and the second cooling coil are connected to the water inlet, and the other end is connected to the water return port. The cooling straight pipe 8 connected to the water inlet includes a first cooling straight pipe and a second cooling straight pipe, one end of the first cooling straight pipe is connected to the first cooling coil, and the other end is connected to the water inlet, and one end of the second cooling straight pipe is connected to the second cooling coil, and the other end is connected to the water inlet. The cooling straight pipe 8 connected to the return water port includes a third cooling straight pipe and a fourth cooling straight pipe. One end of the third cooling straight pipe is connected to the first cooling coil, and the other end is connected to the return water port. One end of the fourth cooling straight pipe is connected to the second cooling coil, and the other end is connected to the return water port. The reinforcing rib 7 is arranged at the connecting corner of the cooling coil 2 and the cooling straight pipe 8 and is used to strengthen the connection between the cooling water pipe 1 and the flange 5. Since there is a large temperature difference between the cooling water pipe 1 and the flange 5, desoldering is likely to occur at the corner, which affects the service life of the flange. Therefore, the reinforcing rib is arranged here to effectively enhance the physical strength of the connection, prevent desoldering and increase the service life of the flange 5.

[0033] Specifically, the inlet flow valve 4 is arranged at the water inlet of the cooling water pipe 1, and the return water thermometer 3 is arranged at the return water outlet of the cooling water pipe 1. The inlet flow valve 4 controls the return water temperature by controlling the inlet flow. When the return water thermometer 3 monitors that the return water temperature increases, the opening of the inlet flow valve 4 is increased; when the return water thermometer 3 monitors that the return water temperature decreases, the opening of the inlet flow valve 4 is reduced. In this embodiment, the inlet flow valve 4 and the return water thermometer 3 are used to monitor the return water temperature, which can effectively evaluate the cooling state of the flange.
