Normal-temperature humidity control storage cabinet

Abstract

The invention discloses a normal-temperature humidity control storage cabinet which comprises an enclosed cabinet body; the enclosed cabinet body is provided with a U-shaped refrigeration cycle air channel; one side of the U-shaped refrigeration cycle air channel is provided with an air cooler, a spiral refrigeration pipeline and a drain pipe sequentially from top to bottom; the refrigeration pipeline is connected with a refrigeration compressor; the lower end of the drain pipe is connected with a water tank; the other side of the U-shaped refrigeration cycle air channel is communicated with the enclosed cabinet body through a cold air opening; the enclosed cabinet is also provided with a heating cycle air channel; the heating cycle air channel is sequentially provided with an air heater, a heating block and a hot air opening from top to bottom; and the heating cycle air channel is communicated with the enclosed cabinet body through the hot air opening. The refrigeration cycle air channel is arranged in a U shape, the cold air opening is arranged on the left side, the air cooler is arranged on the right side; by adoption of the U-shaped arrangement, the refrigeration is more uniform, accumulated water in the refrigeration cycle air channel can be discharged in time, but can not flow back to the cabinet body, thus the refrigeration cycle air channel is ensured to be more stable.

Description

technical field [0001] The invention relates to a storage cabinet, in particular to a humidity control cabinet. Background technique [0002] With the development of science and technology, the storage of precision components has higher and higher requirements for temperature and humidity control. The ordinary moisture-proof boxes and drying boxes on the market today are increasingly unable to meet the demand. Ordinary moisture-proof drying ovens use PTC heating to regenerate hygroscopic materials. This has a great design flaw, because during the heating and regeneration process, the temperature of the entire storage space rises by about 5°C compared to the ambient temperature. The position temperature of the dehumidification host is as high as 40°C-55°C, which will have an adverse effect on raw materials. [0003] Although ordinary dehumidifiers will not increase the ambient temperature, they can only work on the ambient humidity in large airspaces such as warehouses, and...

Today's ordinary moisture-proof boxes and drying boxes on the market are increasingly unable to meet the needs

Ordinary moisture-proof drying ovens use PTC heating to regenerate hygroscopic materials. This has a great design flaw, because during the heating and regeneration process, the temperature of the entire storage space rises by about 5°C compared to the ambient temperature. The position temperature of the dehumidification host is as high as 40°C-55°C, which will cause adverse effects on raw materials

[0003] Although ordinary dehumidifiers will not increase the ambient temperature, they can only work on the ambient humidity in large airspaces such as warehouses, and there will be some dehumidification dead ends; the humidity can only be controlled at about 45% RH, which cannot reach Higher humidity requirements, and the accuracy of humidity control is not high
