Temperature adjusting device

Abstract

The invention discloses a temperature adjusting device, and belongs to the technical field of temperature control. The temperature adjusting device comprises a casing 1, a controller 2, a power supply3, temperature sensors 4, a superhigh temperature protection unit 9 and a superlow temperature protection unit 10 are arranged in the casing, heating elements 6 are uniformly distributed in the internal surface of the casing 1, heat radiation elements 5 are uniformly distributed in the external surface of the casing 1, and the temperature in the casing 1 is adjusted via combined effect of the heating elements 6, heat radiation elements 5, superhigh temperature protection unit 9 and superlow temperature protection unit 10, and kept within a present range; positions where the heat radiation elements 5 and heating elements 6 make contact with the surfaces of the casing are provided with heat-conducting silicone grease layers respectively, and the heat-conducting silicone grease layers accelerate heat transfer between the elements and the casing; and the casing 1 further comprises a temperature display unit 11, and used to display preset upper and lower limits as well as the temperature in the casing 1 in real time.

Description

technical field [0001] The invention relates to the technical field of temperature control, in particular to a temperature regulating device. Background technique [0002] At present, the operating temperature range of most instruments and meters is between 0 and 50°C. For the harsh outdoor environment where some special industries are located, these instruments will not work normally and must be placed in a room with a suitable temperature. For example, in oil well logging operations, the temperature around the oil well is often as low as tens of degrees below zero in winter, while the temperature around the oil well in summer is likely to be higher than 50°C. Coupled with the heat generated by the instrument when it is working, it leads to the surrounding temperature of the oil well. The temperature is far outside the temperature range in which the instrument can operate normally. In view of the above situation, the heat dissipation and cooling of the general instrument i...

Problems solved by technology

However, when the external temperature is too high or too low, the fan not only cannot meet the requirements of the normal operation of the instrument, but also the efficiency is too low and the cooling speed is too slow

However, the constant temperature devices or high and low temperature test chambers currently on the market are either too small to be applied to the above-mentioned instruments, or are too large and heavy to be suitable for outdoor work.
