Low-temperature workbench

Abstract

This article is a low-temperature workbench used, for example, when handling chemicals or specimens at low temperatures. The low-temperature workbench consists of a table body formed by a heat-insulating box body with an open upper part, and a pedestal that supports the table body from below and has a machine room inside. The peripheral side surface of the table body is covered by a first cover that forms the front and rear side surfaces, and a second cover that forms the left and right side surfaces and the ends of the front and rear side surfaces. The joint part of the first and second covers is connected in a substantially flush manner without unevenness, making the appearance of the table body neat. The inside of the table body is divided into an upper working area and a lower cooling area by a plurality of table boards. In the cooling area, an evaporator that constitutes a refrigeration device is installed, and a condensing unit that constitutes the refrigeration device together with the evaporator is installed in the machine room. The table board is provided with a group of blow holes consisting of a group of small-diameter holes that penetrate the table board vertically, and a group of suction holes that lead the air in the working area to the cooling area are provided on the inner surface of the table body facing the left and right of the working area. The air cooled in the cooling area circulates between the two areas through these blow holes and suction holes. On the upper edge of the table body, an indicator light, a display unit that displays the temperature of the working area, and an operation unit that sets the driving state of the refrigeration device are installed. The set state of the refrigeration device can be visually confirmed by the lighting state of the indicator light.
