Described coolant entrance and outlet can be exchanged.
Described cooling medium is water or organic conduction oil,
Described organic conduction oil is glycerine or hydrogenated terphenyl.
Described lead bismuth alloy flow channel adopts stainless steel AISI304 or AISI316 material to make, and other mechanical part materials are comprised of materials such as aluminium alloy, austenitic steel or potteries.
The beneficial effects of the utility model are that this device is a kind of device of realizing flowing heat transfer at bilateral, comprise two kinds of heat transfer flow modes of forced circulation and Natural Circulation; Wherein the lead bismuth alloy fluid is walked inner tube, and chilled water is walked outside annular space passage.The lead bismuth alloy cooling medium heat exchange in this device and the annular space passage of flowing through is conducted heat to the cooling medium of secondary circuit by the liquid lead bismuth alloy through this device, takes away thus the heat of plumbous bismuth fluid; It is simple in structure that outstanding advantages is that this device has, low cost of manufacture, and heat exchange property is good, and plumbous bismuth fluid-pressure drop loss is little, to characteristics such as the type of cooling medium are unrestricted, easily realizes promoting.
