A high-precision constant temperature box

Abstract

The invention discloses a high-accuracy incubator. The high-accuracy incubator comprises an outer incubator body layer, heat preserving layers and temperature control layers, wherein gaps are arranged above and below a third heat preserving layer of the incubator. According to the principle that heat transfer speed of solid is faster than heat transfer speed of air, the heat transfer speed is reduced, heat bridge transfer can be blocked, the heat loss is reduced and the heat preserving performance is better; since multiple heat preserving layers and temperature control layers are arranged at intervals in a socket manner and a design structure of different temperature control components is adopted, the temperature control accuracy is guaranteed to be plus or minus 0.03DEG C; since the incubator is fixed through run-through studs after the incubator is assembled and connecting columns are arranged between every two layers, the seismic performance is improved, the overall structure firmness is guaranteed, and the precision of an appliance preserved inside is prevented from being damaged during handling or transportation.

Description

technical field [0001] The invention relates to the technical field of constant temperature boxes, in particular to a high-precision constant temperature box. Background technique [0002] The constant temperature box, also known as the blast drying box, is the necessary test equipment in the fields of aviation, automobiles, home appliances, scientific research, etc. The high-precision constant temperature box is used to control the ambient temperature of electronic modules that require high ambient temperature. High-precision temperature control is of fundamental importance to modern precision systems. [0003] Most of the incubators are used in laboratories, industries, and medicine. Most of the incubators are electric heating, equipped with electric heaters and temperature regulators, and are boxes or cabinets with insulating materials on the outer walls. [0004] In the laboratory, the incubator will have a great impact on the experimental research process and research ...

AI Technical Summary

Problems solved by technology

The temperature control accuracy of the existing incubator is ±0.1°C, and the anti-seismic performance is average, which cannot fully meet the anti-seismic requirements in the process of handling or transportation. Therefore, the existing incubator still has some defects and cannot well meet the requirements of use.
