Liquid cooling cooling-down type thermostatic bath system and intelligent temperature control method

Abstract

The invention relates to a liquid cooling temperature thermostatic bath system and an intelligent temperature control method thereof, comprising a cooling water tank and a cooling liquid, a liquid bath and a working liquid, and an intelligent temperature controller. The cooling water tank is provided with a water tank temperature sensor and a refrigerator, an electrical heater connected with an electrical heating executor, and a water cooler, a stirrer, a liquid bath temperature sensor, and a water inlet pipe and a water outlet pipe of the water cooler that are connected with the cooling water tank; the other end of the water inlet pipe is connected with a cooling water pump, a signal input end of the intelligent temperature controller is respectively connected with the temperature sensor of the cooling water tank and the temperature sensor of the liquid bath, while the output end is respectively connected with the electrical heating executor, a stirrer engine, the cooling water pump and the refrigerator. The system and the method can drop the temperature at a speed higher than the natural cooling by near 20 times through forced liquid cooling, and can effectively avoid the over regulating of temperature and reduce the negative impact of thermal inertia, thus greatly shortening the precision temperature controlling process and cutting down power consumption.

Description

technical field [0001] The invention relates to a temperature measurement system and a temperature control method, which is a precision temperature control constant temperature tank verification system with fast dynamic characteristics. Background technique [0002] The qualification verification of temperature measuring components has always been an effective means for enterprises and metrology supervision departments to ensure the safe production of enterprises. This type of verification requires a high-performance thermostatic bath with fast response. The traditional constant temperature bath generally uses electric heating elements to heat the liquid medium, and the temperature rise response can be very fast, but the cooling process only depends on natural heat dissipation and cannot be controlled artificially. As a result, the transition process required to reach the temperature required by the verification is very long. As a result, the verification of the temperature...

Problems solved by technology

However, the constant temperature bath using liquid cooling or air cooling means of forced cooling increases the complexity of the equipment and increases the difficulty of temperature control, making it difficult to see reports on the successful development of such devices in China so far.
