A high-efficiency non-magnetic temperature control device based on heat conduction and heat convection

Abstract

An efficient non-magnetic temperature control device based on heat conduction and thermal convection consists of a convection temperature adjustment cabin, an experimental cabin, a radiation temperature adjustment cabinet, and a cooling compressor. The cooling liquid produced by the cooling compressor through the change of state is introduced into the cooling exchange box of the convection temperature adjustment cabin via a main cooling pipe, and flows into a cooling net via a cooling pipe. The air blown by a circulation fan is cooled, then passes through a heating net, and enters the magneticshielding cabin in the experimental cabin via an air hose in order that air flow with adjusted temperature adjust and control the temperature in the experimental cabin rapidly. Another part of the cooling liquid produced by the cooling compressor is introduced into a radiation temperature control box through a secondary cooling pipe. A heating plate and PT1000 thermal resistors are installed in the radiation control temperature box. After the temperature adjustment and control, a submersible pump is used to transfer the liquid with adjusted temperature to a radiant tube through a cold pipe, and the temperature in the experimental cabin is precisely controlled by the temperature radiation. The device uses a dynamic balance method to adjust temperature in combination with convection and radiation, and improves the accuracy and speed of the temperature control of the system.
