Water cooling device of vacuum evaporation equipment for optical filter

Abstract

The invention relates to a water cooling device of vacuum evaporation equipment for an optical filter. A rotating shaft is connected to a mounting and fixing plate in a penetrating manner. One end of the rotating shaft is driven by a motor and is connected with the motor, and the other end of the rotating shaft is fixed together with the bottom end of a water cooling coil. An inner cavity of the water cooling coil is partitioned into an upper cavity layer and a lower cavity layer by a partition plate, and the upper cavity layer is communicated with the lower cavity layer. A water outlet pipe is connected to the inner cavity of the rotating shaft in an inserting manner. One end of the water outlet pipe extends into the upper cavity layer of the water cooling coil and is communicated with the upper cavity layer while the other end of the water outlet pipe is communicated to a water outlet of the water outlet pipe. The rotating shaft is sleeved by a water inlet pipe. One end of the water inlet pipe is communicated with the lower cavity layer of the water cooling coil and the other end of the water inlet pipe is communicated to a water inlet of the water inlet pipe. According to the water cooling device, the rotating shaft is internally provided with the water outlet pipe, the outside of the rotating shaft is sleeved by the water inlet pipe, one end of the water outlet pipe is communicated with the upper cavity layer, and one end of the water inlet pipe is communicated with the lower cavity layer, so that high temperature generated because an electrode bar works for a long term is effectively relieved, the service life of the electrode bar is prolonged, and furthermore the work efficiency is increased.

Description

technical field [0001] The invention relates to a water cooling device, in particular to a water cooling device used in vacuum evaporation equipment for optical filters. Background technique [0002] Water cooling devices are widely used in various fields of industry and agriculture, and cooling equipment can be seen everywhere in people's lives, and it is one of the indispensable process equipment. Especially in the industry, the research on water-cooling devices has been paid much attention. In the industry, the devices will generate heat, and when the heat is too large, it is necessary to discharge or cool the heat without affecting these devices. Otherwise, these devices may There will be damage, which will cause the device to fail to work, and also increase the cost. The general device uses a heat release device to discharge the heat generated by the device to achieve continuous and long-term work. However, for the vacuum evaporation equipment for optical filters, The ...

Especially in the industry, the research of water-cooling devices has been paid much attention. In the industry, the devices will generate heat, and when the heat is too large, it is necessary to discharge or cool the heat without affecting these devices. Otherwise, these devices may There will be damage, which will cause the device to fail to work, and also increase the cost. The general device uses a heat release device to discharge the heat generated by the device to achieve continuous and long-term work. However, for the filter vacuum evaporation equipment, The equipment needs to work continuously and uninterruptedly, and the heat generated by the electrode rods in the equipment needs to be discharged urgently, but the general radiator cannot work for a long time, and the exhaust device can only relatively slow down the increase of the heat, so as to Fundamentally, it is impossible to cool down quickly, resulting in low work efficiency.
