Non-stop tunneling cooling system and non-stop tunneling cooling method for tunneling machine

The invention belongs to the technical field of heading machine cooling systems, and particularly relates to a non-stop heading cooling system and a non-stop heading cooling method for a heading machine. The non-stop tunneling cooling system of the heading machine comprises an internal circulation cooling system, an external circulation cooling system and a main heat exchanger, and further comprises a cold storage system, the cold storage system can exchange heat with the main heat exchanger when the external circulation cooling system stops, and then the heading machine can still work normally; and the external circulation cooling system exchanges heat with the main heat exchanger again. In the whole process, the heading machine cannot be stopped due to the continuous pipe section, so that the heading efficiency is higher. According to the non-stop tunneling cooling method of the tunneling machine, when the tunneling machine is connected with the pipe section, the cooling system of the tunneling machine can
