Heat preservation method and heat preservation equipment of instrument applied to low-temperature environment

Abstract

The invention relates to a heat preservation method and heat preservation equipment of an instrument applied to the low-temperature environment. A control circuit is used for controlling heating and refrigeration according to the detection results of a temperature detector and simultaneously detecting the working current of the instrument in a cabinet and correcting the detection results of the temperature detector according to the calorific value of the working current, thereby controlling the working processes of heating and refrigeration in advance. An automatic adjusting instrument heat preservation box is provided with a temperature detector, a heating mechanism, a refrigerating mechanism and a control circuit; a power supply is connected with a variable multiple-path output power supply part; and a current detector for detecting the working current of electrical equipment required to be subjected to temperature protection is also arranged in a box body, and the output end of the current detector is connected with a calculation function adjustment and control component on the circuit. The heat preservation method and the heat preservation equipment have the beneficial effects that the effect of electrical equipment heating is considered, the calorific value is controlled, the temperature can be adjusted in advance by using a method for detecting the input current of the electrical equipment, the temperature fluctuation is small, and the temperature gradient is small. The heat preservation method and the heat preservation equipment are suitable for the temperature adjustment of the electrical equipment working in the extreme low temperature environment.

Description

technical field [0001] The present invention relates to a heat preservation method and equipment, in particular to a heat preservation method for instruments used in low temperature environments and its heat preservation equipment—an automatic adjustment instrument heat preservation box used in low temperature environments, especially one that can only work at room temperature An incubator for electrical equipment that can work in a low-temperature environment, especially for occasions where the electrical equipment generates heat during operation and the incubator can automatically stabilize the temperature of the incubator with high precision. Background technique [0002] At present, the field of human exploration has penetrated into the harsh environments such as high mountains and polar regions. Especially with the deepening of China’s polar investigations, more and more equipment is installed and operated in the low-temperature environment of the polar regions. ...

Problems solved by technology

However, because the protected electrical equipment will generate heat during operation, and the inertia of heating is large, there is a lag time from the equipment heating to the temperature change, so the temperature in the incubator fluctuates around the set value
