Description

Technical Field

[0001] The present application relates to the technical field of water vapor capture pumps, and in particular to a low-temperature condensation protection structure for water vapor capture pumps. Background Art

[0002] A water vapor capture pump is a device used to extract water vapor from the air. Currently, the domestic low-temperature condensation water vapor capture pump is mainly used to extract water vapor in a vacuum chamber when vacuum coating products such as semiconductors, optical fibers, and flat panel displays.

[0003] In the prior art, an ultra-low temperature water vapor capture pump is connected in series with a water cooler at the exhaust end of the compressor, and the dry filter enters the heat exchanger. After five stages of refrigeration, the temperature reaches minus 120 degrees Celsius, and the refrigerant is then sent into the vacuum coating chamber to capture water vapor.

[0004] The water vapor capture pump generally adopts mechanical compression and cooling technology. Due to the operation of the compressor and cooler, a large amount of heat will be generated. This heat needs to be dissipated in time to ensure that the operating temperature of the cooling system is controlled within an appropriate range. In order to meet the heat dissipation requirements of the water vapor capture pump, a heat dissipation port is usually opened on its shell.

[0005] However, the heat dissipation holes of the water vapor capture pump are mostly exposed to the air, and impurities such as dust can easily enter the interior of the pump body through the heat dissipation holes, which can easily affect the working components inside the pump body.
