Abstract

The invention provides a gas-liquid combined temperature control device, aims to overcome the defects of a heat dissipation technology in a main machine chamber of a geotechnical centrifuge in the prior art, and fully utilizes an inner side liquid cooling wall and outer side air heat exchange fins of a heat exchange device to exchange heat with air in the main machine chamber on the premise of ensuring the smoothness of the inner side wall surface of the main machine chamber. Meanwhile, the temperature control device can operate in a vacuum state, the current situation that a side wall heat exchanger can only utilize the inner side to exchange heat with air and cannot utilize air cooling in the vacuum state is solved, and the heat exchange capacity of the temperature control device is integrally improved. The gas-liquid combined temperature control device is arranged in the main machine chamber of the geotechnical centrifuge and comprises an air inlet channel formed in the top of the inner side wall of the main machine chamber, an air outlet channel formed in the bottom of the main machine chamber of the centrifuge and a side wall heat exchanger, and the lower end of the air inletchannel communicates with the end, close to the inner side wall of the main machine chamber, of the air outlet channel through heat exchange fins.

Description

technical field [0001] The invention relates to the technical field of heat dissipation temperature control equipment, in particular to a heat dissipation temperature control device suitable for the field of geotechnical centrifuge engineering. Background technique [0002] During the high-speed operation of the geotechnical centrifuge, parts such as the rotating arm and the hanging basket rotate, which drives the air in the engine room to flow, causing relative motion between the rotating arm and the support, the rotating arm and the air, and the air and the wall of the machine room to generate heat. These heats accumulate in the machine room, causing the temperature in the machine room to rise, which in turn affects the performance of electronic components such as measurement sensors in the machine room. In order to reduce or even avoid such effects, in order to control the temperature rise of the machine room, a temperature control system must be designed to control the t...
