Abstract

The embodiment of the invention provides a vacuum superconducting electric heater and a manufacturing method thereof. The vacuum superconducting electric heater comprises a heating rod and radiating fins, wherein each radiating fin is in a flaky shape; each radiating fin comprises two cover plates which are buckled together and in welding connection; and grooves on the two cover plates form heat conducting cavities after the two cover plates are buckled together. The manufacturing method comprises: making the cover plates by using a stamping process, and forming a plurality of grooves on the cover plates; buckling the two cover plates and welding the edges of the two cover plates to form a flaky radiating fin, wherein the plurality of grooves on the two cover plates form a plurality of heat conducting cavities after the two cover plates are buckled, and the plurality of heat conducting cavities in one radiating fin are communicated through a gap between the cover plates; and welding the interfaces of the radiating fins to connect the adjacent radiating fins. The radiating fins are arranged in a flaky shape, so that the heat dissipating areas of the radiating fins are increased and the heat dissipating efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to vacuum superconducting heat heating technology, in particular to a vacuum superconducting heater and a manufacturing method thereof. Background technique [0002] In the past, electric heaters used for heating mainly used heating elements such as electric heating tubes or heating films, and used water and oil as heat transfer carriers for heating. At present, with the development of vacuum superconducting technology, vacuum superconducting heaters emerge as the times require. [0003] figure 1 It is a structural schematic diagram of a vacuum superconducting heater in the prior art. like figure 1 As shown, the vacuum superconducting heater generally consists of heat sinks 101 and heating rods 103 . Radiating fins 101 are generally cylindrical tubes made of cast iron. Interfaces 102 are formed on both sides of each cooling fin 101. The interfaces 102 of adjacent cooling fins 101 are connected by internal...
