Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cold boxes, in particular to a horizontal vacuum cold box. Background Technique

[0002] A cold box is a group of highly efficient and adiabatic low-temperature heat exchange equipment, which can be applied to various occasions. Under low air pressure, the boiling point of water decreases and the latent heat of evaporation increases. The free water on the surface of the object to be cooled vaporizes, taking away its own and environmental heat. The vacuum cold box facilitates the use of this principle to achieve the cooling effect.

[0003] A vacuum cold box is a cooling processing equipment that uses a vacuum pump to extract air and water vapor in a vacuum tank to reduce the air pressure in the vacuum box body. However, most of the current vacuum cold boxes are vertical cold boxes. When placing or moving them, the occupied space of the cold box needs to be considered. At the same time, the box door is usually hinged by a hinge, and a large space is occupied when opening the box door. For this reason, we propose a horizontal vacuum cold box.
