Therefore, when the cold-heat exchanger stops operating in winter and the ambient temperature is low, the liquid medium in the heat exchange tube must be evacuated to avoid frost cracking and frostbite on the cold-heat exchanger.
At present, the emptying mode of a cold-heat exchanger in the market is mainly to enable a heat exchange liquid medium in the heat exchanger to freely flow out under the action of gravity through the arrangement of horizontal heat exchange pipelines. However, the pipe diameter that should be for the heat exchange tube in the interchanger is less, and heat transfer liquid all has certain viscosity, and there is certain resistance when flowing in the heat exchange tube, leads to the heat transfer liquid medium in the heat exchange tube to hardly realize effectual evacuation under natural state: especially, when the heat exchange tube is long and the installation is not smooth, the viscous resistance of the heat exchange liquid medium is increased and the gravity guide deviation is caused, so that the evacuation of the heat exchange liquid medium is very difficult. If the heat exchange liquid medium in the heat exchange tube cannot be effectively emptied, and the surrounding environment is lower than the freezing point of the liquid medium, the cold air can cause solidification and expansion of the heat exchange liquid medium retained in the heat exchange tube, so that the cold-heat exchanger is broken and damaged, and the loss is caused to a user. In addition, under the condition that the cold-heat exchanger does not operate in winter, in order to ensure that the heat exchange liquid medium in the cold-heat exchanger can be thoroughly emptied and discharged, only manual water drainage and forced emptying by using high-pressure air purging and the like can be performed, so that the labor cost is increased, the manual influence condition is large, the process stability is poor, certain difficulty exists in management in work, the maintenance and management are difficult, and the cost is increased.
Therefore, it is desirable to provide an anti-freeze heat exchanger capable of solving the above problems.
