The utility model solves the technical scheme that its technical problem adopts:
A kind of gilled radiator, comprise super thin metal pipe, be serially connected with multiple radiating fin outside described super thin metal pipe, the outer wall of super thin metal pipe is combined with radiating fin interference by expand tube, is provided with electric heater unit in described super thin metal pipe.
As the further improved procedure of such scheme, described super thin metal thickness of pipe wall is 0.06 ~ 0.18mm.Because tube wall is very thin, make super thin metal pipe for good heat conductivility, heat transfer coefficient is higher than 300, and heat dispersion is very good; And its stress is little, certain expansion deformation can be born, interference can be formed with radiating fin and be combined after expand tube, and interference wire casing has good ripple elasticity, guarantee radiating fin and tube wall good contact, thermal conduction resistance between the two can not increase in time, and thermal diffusivity is unattenuated.
As the further improved procedure of such scheme, the magnitude of interference of described super thin metal pipe and radiating fin is 0.05 ~ 0.20mm.
As the further improved procedure of such scheme, described super thin metal pipe is steel pipe, aluminum pipe or copper pipe.
As the further improved procedure of such scheme, described radiating fin is aluminium foil or Copper Foil material.
As the further improved procedure of such scheme, described electric heater unit comprises and being arranged in super thin metal pipe and the heating wire of tube wall dielectric separation with super thin metal pipe.
As the further improved procedure of such scheme, in described super thin metal pipe, be filled with magnesium oxide powder.
The beneficial effects of the utility model are:
Gilled radiator of the present utility model adopts super thin metal pipe and radiating fin interference to be combined into, effectively reduce the situation about being separated from each other caused because of thermal deformation between tubing and radiating fin, make overall thermal resistance can not passing in time and increasing, extend the service life of equipment, also reduce potential safety hazard.
