Abstract
The utility model provides an energy-saving heat radiating tube with low cost. The energy-saving heat radiating tube comprises an inner tube and an outer tube which are fixed to each other, wherein the inner tube is made of copper, and a plurality of heat radiating fins which are longitudinally arranged are arranged on the inner wall of the inner tube; and the outer tube is made of aluminum alloy, and a plurality of spiral fins are arranged on the outer wall of the outer tube along the axial direction. The utility model has the beneficial effect that the energy-saving heat radiating tube is formed by compounding the inner tube and the outer tube which are fixed to each other, is strong in corrosion resistance because the inner tube is made of copper as well as is light in weight and low in cost because the outer tube is made of aluminum alloy; because the heat radiating fins are arranged on the inner wall of the inner tube and the spiral fins are arranged on the outer wall of the outer tube, the heat radiating area is increased, the heat radiating effect is good and the energy sources are saved; and the energy-saving heat radiating tube has the advantages of simple structure, low cost, high strength, corrosion resistance and the like.
Description
Technical field
The utility model relates to a kind of hardware of heat transmission, especially relates to the low energy-saving radiating pipe of a kind of cost.
Background technology
In the equipment of many heat exchanges, need to adopt radiating tube to carry out heat exchange, usually inside and outside pipe, pass to different media, carry out heat exchange by the temperature of medium.At present, the radiating tube of being made by homogenous material such as the radiator of aluminum radiating tube, though have light and the low characteristics of price, can not be taken into account not only anticorrosive but also requirement that price is low; Also existing the radiating tube that China uses in heat abstractor mostly is that cross section is circular, oblate, square, deltiod, these radiating tube external surface areas are all less, increased the volume of heat dissipation equipment, limited radiating effect, wasted heat energy, make heat all not be absorbed conversion, affected the life-span of equipment, increased cost.
Summary of the invention
Problem to be solved in the utility model provides that a kind of cost is low, good heat dissipation effect, the low energy-saving radiating pipe of a kind of cost that resistance to corrosion is strong, especially is fit to use on the heat abstractor.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the energy-saving radiating pipe that a kind of cost is low, comprise the inner and outer tubes that interfix, and the material of described inner tube is copper, described inner tube wall is provided with the radiating fin of some longitudinal arrangements; The material of described outer tube is aluminium alloy, is provided with vertically some helical fins on the outer wall of described outer tube.
Further, the quantity of described radiating fin is 5.
Further, the quantity of described helical fin is two, and the distance between two described helical fins is 1.5mm.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, be composited by the inner and outer tubes that interfix, because inner tube is copper material, corrosion resistance is strong, and outer tube is aluminium alloy, and not only quality is light, and cost is low; Inner tube wall is provided with radiating fin and outer tube outer wall is provided with helical fin, has increased area of dissipation, good heat dissipation effect, energy savings; Have simple in structure, cost is low, intensity is high, the advantage such as anticorrosive.
